Fixes for winelib building (used by our Coverity build). Avoided referring to some functions and header files that aren't there in the winelib world (_vsnprintf, _stricmp, SecureZeroMemory, multimon.h), and worked around a really amazingly annoying issue in which Winelib objects to you using the type 'fd_set' unless you included winsock2.h before stdlib.h.

Major destabilisation, phase 1. In this phase I've moved (I think) all the global and function-static variables out of terminal.c into a dynamically allocated data structure. Note that this does not yet confer the ability to run more than one of them in the same process, because other things (the line discipline, the back end) are still global, and also in particular the address of the dynamically allocated terminal-data structure is held in a global variable `term'. But what I've got here represents a reasonable stopping point at which to check things in. In _theory_ this should all still work happily, on both Unix and Windows. In practice, who knows?

Make our process's ACL more restrictive. By default Windows processes have wide open ACLs which allow interference by other processes running as the same user. Adjust our ACL to make this a bit harder. Because it's useful to protect PuTTYtel as well, carve winsecur.c into advapi functions and wincapi.c for crypt32 functions.

GUI PuTTY: stop using the global 'hwnd'. This was the difficult part of cleaning up that global variable. The main Windows PuTTY GUI is split between source files, so that _does_ actually need to refer to the main window from multiple places. But all the places where windlg.c needed to use 'hwnd' are seat methods, so they were already receiving a Seat pointer as a parameter. In other words, the methods of the Windows GUI Seat were already split between source files. So it seems only fair that they should be able to share knowledge of the seat's data as well. Hence, I've created a small 'WinGuiSeat' structure which both window.c and windlg.c can see the layout of, and put the main terminal window handle in there. Then the seat methods implemented in windlg.c, like win_seat_verify_ssh_host_key, can use container_of to turn the Seat pointer parameter back into the address of that structure, just as the methods in window.c can do (even though they currently don't need to). (Who knows: now that it _exists_, perhaps that structure can be gradually expanded in future to turn it into a proper encapsulation of all the Windows frontend's state, like we should have had all along...) I've also moved the Windows GUI LogPolicy implementation into the same object (i.e. WinGuiSeat implements both traits at once). That allows win_gui_logging_error to recover the same WinGuiSeat from its input LogPolicy pointer, which means it can get from there to the Seat facet of the same object, so that I don't need the extern variable 'win_seat' any more either.

The WinSock library is now loaded at run-time, which means we can attempt to load WS2 and then fall back to WS1 if that fails. This should allow us to use WS2-specific functionality to find out the local system's list of IP addresses, thus fixing winnet-if2lo, while degrading gracefully back to the previous behaviour if that functionality is unavailable. (I haven't yet actually done this; I've just laid the groundwork.) This checkin _may_ cause instability; it seemed fine to me on initial testing, but it's a bit of an upheaval and I wouldn't like to make bets on it just yet. [originally from svn r3502]

Add GUI configuration for choice of clipboards. On all platforms, you can now configure which clipboard the mouse pastes from, which clipboard Ctrl-Ins and Shift-Ins access, and which Ctrl-Shift-C and Ctrl-Shift-V access. In each case, the options are: - nothing at all - a clipboard which is implicitly written by the act of mouse selection (the PRIMARY selection on X, CLIP_LOCAL everywhere else) - the standard clipboard written by explicit copy/paste UI actions (CLIPBOARD on X, the unique system clipboard elsewhere). Also, you can control whether selecting text with the mouse _also_ writes to the explicitly accessed clipboard. The wording of the various messages changes between platforms, but the basic UI shape is the same everywhere.

I can't find any documentation that puts an upper limit on the number of menu items, and it seems to work on Win98, which is where I'd expect it to break if anywhere.

Remove agent_schedule_callback(). This is another piece of the old 2003 attempt at async agent requests. Nothing ever calls this function (in particular, the new working version of async-agent doesn't need it). Remove it completely, and all its special-window-message implementations too. (If we _were_ still using this function, then it would surely be possible to fold it into the more recently introduced general toplevel-callback system, and get rid of all this single-use special code. But we're not, so removing it completely is even easier.) In particular, this system was the only reason why Windows Plink paid any attention to its message queue. So now I can make it call plain WaitForMultipleObjects instead of MsgWaitForMultipleObjects.

Handle the VK_PACKET virtual key code. This is generated in response to the SendInput() Windows API call, if that in turn is passed an KEYBDINPUT structure with KEYEVENTF_UNICODE set. That method of input generation is used by programs such as 'WinCompose' to send an arbitrary Unicode character as if it had been typed at the keyboard, even if the keyboard doesn't actually provide a key for it. Like VK_PROCESSKEY, this key code is an exception to our usual policy of manually translating keystrokes: we handle it by calling TranslateMessage, to get back the Unicode character it contains as a WM_CHAR message. (If that Unicode character in turn is outside the BMP, it may come back as a pair of WM_CHARs in succession containing UTF-16 surrogates; if so, that's OK, because the new Unicode WM_CHAR handler can cope.)

Fixed (on all platforms). Therefore, since the global sesslist didn't seem to be useful, I've got rid of it; config.c creates one as needed, as do the frontends. (Not tried compiling Mac changes.)

Convert a lot of 'int' variables to 'bool'. My normal habit these days, in new code, is to treat int and bool as _almost_ completely separate types. I'm still willing to use C's implicit test for zero on an integer (e.g. 'if (!blob.len)' is fine, no need to spell it out as blob.len != 0), but generally, if a variable is going to be conceptually a boolean, I like to declare it bool and assign to it using 'true' or 'false' rather than 0 or 1. PuTTY is an exception, because it predates the C99 bool, and I've stuck to its existing coding style even when adding new code to it. But it's been annoying me more and more, so now that I've decided C99 bool is an acceptable thing to require from our toolchain in the first place, here's a quite thorough trawl through the source doing 'boolification'. Many variables and function parameters are now typed as bool rather than int; many assignments of 0 or 1 to those variables are now spelled 'true' or 'false'. I managed this thorough conversion with the help of a custom clang plugin that I wrote to trawl the AST and apply heuristics to point out where things might want changing. So I've even managed to do a decent job on parts of the code I haven't looked at in years! To make the plugin's work easier, I pushed platform front ends generally in the direction of using standard 'bool' in preference to platform-specific boolean types like Windows BOOL or GTK's gboolean; I've left the platform booleans in places they _have_ to be for the platform APIs to work right, but variables only used by my own code have been converted wherever I found them. In a few places there are int values that look very like booleans in _most_ of the places they're used, but have a rarely-used third value, or a distinction between different nonzero values that most users don't care about. In these cases, I've _removed_ uses of 'true' and 'false' for the return values, to emphasise that there's something more subtle going on than a simple boolean answer: - the 'multisel' field in dialog.h's list box structure, for which the GTK front end in particular recognises a difference between 1 and 2 but nearly everything else treats as boolean - the 'urgent' parameter to plug_receive, where 1 vs 2 tells you something about the specific location of the urgent pointer, but most clients only care about 0 vs 'something nonzero' - the return value of wc_match, where -1 indicates a syntax error in the wildcard. - the return values from SSH-1 RSA-key loading functions, which use -1 for 'wrong passphrase' and 0 for all other failures (so any caller which already knows it's not loading an _encrypted private_ key can treat them as boolean) - term->esc_query, and the 'query' parameter in toggle_mode in terminal.c, which _usually_ hold 0 for ESC[123h or 1 for ESC[?123h, but can also hold -1 for some other intervening character that we don't support. In a few places there's an integer that I haven't turned into a bool even though it really _can_ only take values 0 or 1 (and, as above, tried to make the call sites consistent in not calling those values true and false), on the grounds that I thought it would make it more confusing to imply that the 0 value was in some sense 'negative' or bad and the 1 positive or good: - the return value of plug_accepting uses the POSIXish convention of 0=success and nonzero=error; I think if I made it bool then I'd also want to reverse its sense, and that's a job for a separate piece of work. - the 'screen' parameter to lineptr() in terminal.c, where 0 and 1 represent the default and alternate screens. There's no obvious reason why one of those should be considered 'true' or 'positive' or 'success' - they're just indices - so I've left it as int. ssh_scp_recv had particularly confusing semantics for its previous int return value: its call sites used '<= 0' to check for error, but it never actually returned a negative number, just 0 or 1. Now the function and its call sites agree that it's a bool. In a couple of places I've renamed variables called 'ret', because I don't like that name any more - it's unclear whether it means the return value (in preparation) for the _containing_ function or the return value received from a subroutine call, and occasionally I've accidentally used the same variable for both and introduced a bug. So where one of those got in my way, I've renamed it to 'toret' or 'retd' (the latter short for 'returned') in line with my usual modern practice, but I haven't done a thorough job of finding all of them. Finally, one amusing side effect of doing this is that I've had to separate quite a few chained assignments. It used to be perfectly fine to write 'a = b = c = TRUE' when a,b,c were int and TRUE was just a the 'true' defined by stdbool.h, that idiom provokes a warning from gcc: 'suggest parentheses around assignment used as truth value'!

Convert a lot of 'int' variables to 'bool'. My normal habit these days, in new code, is to treat int and bool as _almost_ completely separate types. I'm still willing to use C's implicit test for zero on an integer (e.g. 'if (!blob.len)' is fine, no need to spell it out as blob.len != 0), but generally, if a variable is going to be conceptually a boolean, I like to declare it bool and assign to it using 'true' or 'false' rather than 0 or 1. PuTTY is an exception, because it predates the C99 bool, and I've stuck to its existing coding style even when adding new code to it. But it's been annoying me more and more, so now that I've decided C99 bool is an acceptable thing to require from our toolchain in the first place, here's a quite thorough trawl through the source doing 'boolification'. Many variables and function parameters are now typed as bool rather than int; many assignments of 0 or 1 to those variables are now spelled 'true' or 'false'. I managed this thorough conversion with the help of a custom clang plugin that I wrote to trawl the AST and apply heuristics to point out where things might want changing. So I've even managed to do a decent job on parts of the code I haven't looked at in years! To make the plugin's work easier, I pushed platform front ends generally in the direction of using standard 'bool' in preference to platform-specific boolean types like Windows BOOL or GTK's gboolean; I've left the platform booleans in places they _have_ to be for the platform APIs to work right, but variables only used by my own code have been converted wherever I found them. In a few places there are int values that look very like booleans in _most_ of the places they're used, but have a rarely-used third value, or a distinction between different nonzero values that most users don't care about. In these cases, I've _removed_ uses of 'true' and 'false' for the return values, to emphasise that there's something more subtle going on than a simple boolean answer: - the 'multisel' field in dialog.h's list box structure, for which the GTK front end in particular recognises a difference between 1 and 2 but nearly everything else treats as boolean - the 'urgent' parameter to plug_receive, where 1 vs 2 tells you something about the specific location of the urgent pointer, but most clients only care about 0 vs 'something nonzero' - the return value of wc_match, where -1 indicates a syntax error in the wildcard. - the return values from SSH-1 RSA-key loading functions, which use -1 for 'wrong passphrase' and 0 for all other failures (so any caller which already knows it's not loading an _encrypted private_ key can treat them as boolean) - term->esc_query, and the 'query' parameter in toggle_mode in terminal.c, which _usually_ hold 0 for ESC[123h or 1 for ESC[?123h, but can also hold -1 for some other intervening character that we don't support.

static void process_clipdata(HGLOBAL clipdata, bool unicode);
Add GUI configuration for choice of clipboards. On all platforms, you can now configure which clipboard the mouse pastes from, which clipboard Ctrl-Ins and Shift-Ins access, and which Ctrl-Shift-C and Ctrl-Shift-V access. In each case, the options are: - nothing at all - a clipboard which is implicitly written by the act of mouse selection (the PRIMARY selection on X, CLIP_LOCAL everywhere else) - the standard clipboard written by explicit copy/paste UI actions (CLIPBOARD on X, the unique system clipboard elsewhere). Also, you can control whether selecting text with the mouse _also_ writes to the explicitly accessed clipboard. The wording of the various messages changes between platforms, but the basic UI shape is the same everywhere.

Whitespace rationalisation of entire code base. The number of people has been steadily increasing who read our source code with an editor that thinks tab stops are 4 spaces apart, as opposed to the traditional tty-derived 8 that the PuTTY code expects. So I've been wondering for ages about just fixing it, and switching to a spaces-only policy throughout the code. And I recently found out about 'git blame -w', which should make this change not too disruptive for the purposes of source-control archaeology; so perhaps now is the time. While I'm at it, I've also taken the opportunity to remove all the trailing spaces from source lines (on the basis that git dislikes them, and is the only thing that seems to have a strong opinion one way or the other). Apologies to anyone downstream of this code who has complicated patch sets to rebase past this change. I don't intend it to be needed again.

Expose the Ldisc structure tag throughout the code. That's one fewer anonymous 'void *' which might be accidentally confused with some other pointer type if I misremember the order of function arguments. While I'm here, I've made its pointer-nature explicit - that is, 'Ldisc' is now a typedef for the structure type itself rather than a pointer to it. A stylistic change only, but it feels more natural to me these days for a thing you're going to eventually pass to a 'free' function.

Turn Backend into a sensible classoid. Nearly every part of the code that ever handles a full backend structure has historically done it using a pair of pointer variables, one pointing at a constant struct full of function pointers, and the other pointing to a 'void *' state object that's passed to each of those. While I'm modernising the rest of the code, this seems like a good time to turn that into the same more or less type-safe and less cumbersome system as I'm using for other parts of the code, such as Socket, Plug, BinaryPacketProtocol and so forth: the Backend structure contains a vtable pointer, and a system of macro wrappers handles dispatching through that vtable.

PuTTY is an exception, because it predates the C99 bool, and I've stuck to its existing coding style even when adding new code to it. But it's been annoying me more and more, so now that I've decided C99 bool is an acceptable thing to require from our toolchain in the first place, here's a quite thorough trawl through the source doing 'boolification'. Many variables and function parameters are now typed as bool rather than int; many assignments of 0 or 1 to those variables are now spelled 'true' or 'false'. I managed this thorough conversion with the help of a custom clang plugin that I wrote to trawl the AST and apply heuristics to point out where things might want changing. So I've even managed to do a decent job on parts of the code I haven't looked at in years! To make the plugin's work easier, I pushed platform front ends generally in the direction of using standard 'bool' in preference to platform-specific boolean types like Windows BOOL or GTK's gboolean; I've left the platform booleans in places they _have_ to be for the platform APIs to work right, but variables only used by my own code have been converted wherever I found them. In a few places there are int values that look very like booleans in _most_ of the places they're used, but have a rarely-used third value, or a distinction between different nonzero values that most users don't care about. In these cases, I've _removed_ uses of 'true' and 'false' for the return values, to emphasise that there's something more subtle going on than a simple boolean answer: - the 'multisel' field in dialog.h's list box structure, for which the GTK front end in particular recognises a difference between 1 and 2 but nearly everything else treats as boolean - the 'urgent' parameter to plug_receive, where 1 vs 2 tells you something about the specific location of the urgent pointer, but most clients only care about 0 vs 'something nonzero' - the return value of wc_match, where -1 indicates a syntax error in the wildcard. - the return values from SSH-1 RSA-key loading functions, which use -1 for 'wrong passphrase' and 0 for all other failures (so any caller which already knows it's not loading an _encrypted private_ key can treat them as boolean) - term->esc_query, and the 'query' parameter in toggle_mode in terminal.c, which _usually_ hold 0 for ESC[123h or 1 for ESC[?123h, but can also hold -1 for some other intervening character that we don't support. In a few places there's an integer that I haven't turned into a bool even though it really _can_ only take values 0 or 1 (and, as above, tried to make the call sites consistent in not calling those values true and false), on the grounds that I thought it would make it more confusing to imply that the 0 value was in some sense 'negative' or bad and the 1 positive or good: - the return value of plug_accepting uses the POSIXish convention of 0=success and nonzero=error; I think if I made it bool then I'd also want to reverse its sense, and that's a job for a separate piece of work. - the 'screen' parameter to lineptr() in terminal.c, where 0 and 1 represent the default and alternate screens. There's no obvious reason why one of those should be considered 'true' or 'positive' or 'success' - they're just indices - so I've left it as int. ssh_scp_recv had particularly confusing semantics for its previous int return value: its call sites used '<= 0' to check for error, but it never actually returned a negative number, just 0 or 1. Now the function and its call sites agree that it's a bool. In a couple of places I've renamed variables called 'ret', because I don't like that name any more - it's unclear whether it means the return value (in preparation) for the _containing_ function or the return value received from a subroutine call, and occasionally I've accidentally used the same variable for both and introduced a bug. So where one of those got in my way, I've renamed it to 'toret' or 'retd' (the latter short for 'returned') in line with my usual modern practice, but I haven't done a thorough job of finding all of them. Finally, one amusing side effect of doing this is that I've had to separate quite a few chained assignments. It used to be perfectly fine to write 'a = b = c = TRUE' when a,b,c were int and TRUE was just a the 'true' defined by stdbool.h, that idiom provokes a warning from gcc: 'suggest parentheses around assignment used as truth value'!

Rework special-commands system to add an integer argument. In order to list cross-certifiable host keys in the GUI specials menu, the SSH backend has been inventing new values on the end of the Telnet_Special enumeration, starting from the value TS_LOCALSTART. This is inelegant, and also makes it awkward to break up special handlers (e.g. to dispatch different specials to different SSH layers), since if all you know about a special is that it's somewhere in the TS_LOCALSTART+n space, you can't tell what _general kind_ of thing it is. Also, if I ever need another open-ended set of specials in future, I'll have to remember which TS_LOCALSTART+n codes are in which set. So here's a revamp that causes every special to take an extra integer argument. For all previously numbered specials, this argument is passed as zero and ignored, but there's a new main special code for SSH host key cross-certification, in which the integer argument is an index into the backend's list of available keys. TS_LOCALSTART is now a thing of the past: if I need any other open-ended sets of specials in future, I can add a new top-level code with a nicely separated space of arguments. While I'm at it, I've removed the legacy misnomer 'Telnet_Special' from the code completely; the enum is now SessionSpecialCode, the struct containing full details of a menu entry is SessionSpecial, and the enum values now start SS_ rather than TS_.

Turned the old `Telnet Command' System-submenu into a more general `Special Command' menu, in which any backend can place its own list of magical things the user might want to ask the backend to do. In particular I've implemented the recently proposed "break" extension in SSH2 using this mechanism. NB this checkin slightly breaks the Mac build, since it needs to provide at least a stub form of update_specials_menu(). [originally from svn r3054]

New timing infrastructure. There's a new function schedule_timer() which pretty much any module can call to request a call-back in the future. So terminal.c can do its own handling of blinking, visual bells and deferred screen updates, without having to rely on term_update() being called 50 times a second (fixes: pterm-timer); and ssh.c and telnet.c both invoke a new module pinger.c which takes care of sending keepalives, so they get sent uniformly in all front ends (fixes: plink-keepalives, unix-keepalives).

If a new session was saved from Change Settings, a side-effect on Windows was that the global `sesslist' got out of sync with the saved-sessions submenu, causing the latter to launch the wrong sessions. Also, Change Settings wasn't getting a fresh session list, so if the set of sessions had changed since session startup it wouldn't reflect that (at least until a session was saved). Fixed (on all platforms). Therefore, since the global sesslist didn't seem to be useful, I've got rid of it; config.c creates one as needed, as do the frontends. (Not tried compiling Mac changes.) Also, we now build the saved-sessions submenu on demand on Windows and Unix. (This should probably also be done on the Mac.) [originally from svn r5609]

Stop having a global Conf. It's now a static in the main source file of each application that uses it, and isn't accessible from any other source file unless the main one passes it by reference. In fact, there were almost no instances of the latter: only the config-box functions in windlg.c were using 'conf' by virtue of its globalness, and it's easy to make those take it as a parameter.

Remove remaining uses of the GLOBAL macro. We now have no remaining things in header files that switch from being a declaration to a definition depending on an awkward #define at the point of including that header. There are still a few mutable variables with external linkage, but at least now each one is defined in a specific source file file appropriate to its purpose and context. The remaining globals as of this commit were: - 'logctx' and 'term', which never needed to be globals in the first place, because they were never actually shared between source files. Now 'term' is just a static in window.c, and 'logctx' is a static in each of that and winplink.c. - 'hinst', which still has external linkage, but is now defined separately in each source file that sets it up (i.e. those with a WinMain) - osMajorVersion, osMinorVersion and osPlatformId, whose definitions now live in winmisc.c alongside the code which sets them up. (Actually they were defined there all along, it turns out, but every toolchain I've built with has commoned them together with the version defined by the GLOBAL in the header.) - 'hwnd', which nothing was actually _using_ any more after previous commits, so all this commit had to do was delete it.

Post-release destabilisation! Completely remove the struct type 'Config' in putty.h, which stores all PuTTY's settings and includes an arbitrary length limit on every single one of those settings which is stored in string form. In place of it is 'Conf', an opaque data type everywhere outside the new file conf.c, which stores a list of (key, value) pairs in which every key contains an integer identifying a configuration setting, and for some of those integers the key also contains extra parts (so that, for instance, CONF_environmt is a string-to-string mapping). Everywhere that a Config was previously used, a Conf is now; everywhere there was a Config structure copy, conf_copy() is called; every lookup, adjustment, load and save operation on a Config has been rewritten; and there's a mechanism for serialising a Conf into a binary blob and back for use with Duplicate Session. User-visible effects of this change _should_ be minimal, though I don't doubt I've introduced one or two bugs here and there which will eventually be found. The _intended_ visible effects of this change are that all arbitrary limits on configuration strings and lists (e.g. limit on number of port forwardings) should now disappear; that list boxes in the configuration will now be displayed in a sorted order rather than the arbitrary order in which they were added to the list (since the underlying data structure is now a sorted tree234 rather than an ad-hoc comma-separated string); and one more specific change, which is that local and dynamic port forwardings on the same port number are now mutually exclusive in the configuration (putting 'D' in the key rather than the value was a mistake in the first place). One other reorganisation as a result of this is that I've moved all the dialog.c standard handlers (dlg_stdeditbox_handler and friends) out into config.c, because I can't really justify calling them generic any more. When they took a pointer to an arbitrary structure type and the offset of a field within that structure, they were independent of whether that structure was a Config or something completely different, but now they really do expect to talk to a Conf, which can _only_ be used for PuTTY configuration, so I've renamed them all things like conf_editbox_handler and moved them out of the nominally independent dialog-box management module into the PuTTY-specific config.c.

Make more file-scope variables static. In the previous trawl of this, I didn't bother with the statics in main-program modules, on the grounds that my main aim was to avoid 'library' objects (shared between multiple programs) from polluting the global namespace. But I think it's worth being more strict after all, so this commit adds 'static' to a lot more file-scope variables that aren't needed outside their own module.

Having laid all the groundwork, we can now remove the global `cfg' completely from putty.h. It's now static in each of the command-line front ends, shared only between window.c and windlg.c in PuTTY proper (I've tested this by doing #define cfg cfgsillyname in those two files only, and it still links so nobody else is using that symbol!), and part of the `inst' structure in pterm. I think that only leaves the Unicode module as the last stubborn holdout in the anti-global-variables campaign. [originally from svn r2568]

In a few places there's an integer that I haven't turned into a bool even though it really _can_ only take values 0 or 1 (and, as above, tried to make the call sites consistent in not calling those values true and false), on the grounds that I thought it would make it more confusing to imply that the 0 value was in some sense 'negative' or bad and the 1 positive or good: - the return value of plug_accepting uses the POSIXish convention of 0=success and nonzero=error; I think if I made it bool then I'd also want to reverse its sense, and that's a job for a separate piece of work. - the 'screen' parameter to lineptr() in terminal.c, where 0 and 1 represent the default and alternate screens. There's no obvious reason why one of those should be considered 'true' or 'positive' or 'success' - they're just indices - so I've left it as int. ssh_scp_recv had particularly confusing semantics for its previous int return value: its call sites used '<= 0' to check for error, but it never actually returned a negative number, just 0 or 1. Now the function and its call sites agree that it's a bool. In a couple of places I've renamed variables called 'ret', because I don't like that name any more - it's unclear whether it means the return value (in preparation) for the _containing_ function or the return value received from a subroutine call, and occasionally I've accidentally used the same variable for both and introduced a bug. So where one of those got in my way, I've renamed it to 'toret' or 'retd' (the latter short for 'returned') in line with my usual modern practice, but I haven't done a thorough job of finding all of them. Finally, one amusing side effect of doing this is that I've had to separate quite a few chained assignments. It used to be perfectly fine to write 'a = b = c = TRUE' when a,b,c were int and TRUE was just a the 'true' defined by stdbool.h, that idiom provokes a warning from gcc: 'suggest parentheses around assignment used as truth value'!

Bring some order to colour palette indexing. There are three separate indexing schemes in use by various bits of the PuTTY front ends, and _none_ of them was clearly documented, let alone all in the same place. Worse, functions that looked obviously related, like win_palette_set and win_palette_get, used different encodings. Now all the encodings are defined together in putty.h, with explanation of why there are three in the first place and clear documentation of where each one is used; terminal.c provides mapping tables that convert between them; the terminology is consistent throughout; and win_palette_set has been converted to use the sensible encoding.

Centralise palette setup into terminal.c. Now terminal.c makes nearly all the decisions about what the colour palette should actually contain: it does the job of reading the GUI-configurable colours out of Conf, and also the job of making up the rest of the xterm-256 palette. The only exception is that TermWin can provide a method to override some of the default colours, which on Windows is used to implement the 'Use system colours' config option. This saves code overall, partly because the front ends don't have to be able to send palette data back to the Terminal any more (the Terminal keeps the master copy and can answer palette-query escape sequences from its own knowledge), and also because now there's only one copy of the xterm-256 palette setup code (previously gtkwin.c and window.c each had their own version of it). In this rewrite, I've also introduced a multi-layered storage system for the palette data in Terminal. One layer contains the palette information derived from Conf; the next contains platform overrides (currently just Windows's 'Use system colours'); the last one contains overrides set by escape sequences in the middle of the session. The topmost two layers can each _conditionally_ override the ones below. As a result, if a server-side application manually resets (say) the default fg and bg colours in mid-session to something that works well in a particular application, those changes won't be wiped out by a change in the Windows system colours or the Conf, which they would have been before. Instead, changes in Conf or the system colours alter the lower layers of the structure, but then when palette_rebuild is called, the upper layer continues to override them, until a palette reset (ESC]R) or terminal reset (e.g. ESC c) removes those upper-layer changes. This seems like a more consistent strategy, in that the same set of configuration settings will produce the same end result regardless of what order they were applied in. The palette-related methods in TermWin have had a total rework. palette_get and palette_reset are both gone; palette_set can now set a contiguous range of colours in one go; and the new palette_get_overrides replaces window.c's old systopalette().

/* this allows xterm-style mouse handling. */
Convert a lot of 'int' variables to 'bool'. My normal habit these days, in new code, is to treat int and bool as _almost_ completely separate types. I'm still willing to use C's implicit test for zero on an integer (e.g. 'if (!blob.len)' is fine, no need to spell it out as blob.len != 0), but generally, if a variable is going to be conceptually a boolean, I like to declare it bool and assign to it using 'true' or 'false' rather than 0 or 1. PuTTY is an exception, because it predates the C99 bool, and I've stuck to its existing coding style even when adding new code to it. But it's been annoying me more and more, so now that I've decided C99 bool is an acceptable thing to require from our toolchain in the first place, here's a quite thorough trawl through the source doing 'boolification'. Many variables and function parameters are now typed as bool rather than int; many assignments of 0 or 1 to those variables are now spelled 'true' or 'false'. I managed this thorough conversion with the help of a custom clang plugin that I wrote to trawl the AST and apply heuristics to point out where things might want changing. So I've even managed to do a decent job on parts of the code I haven't looked at in years! To make the plugin's work easier, I pushed platform front ends generally in the direction of using standard 'bool' in preference to platform-specific boolean types like Windows BOOL or GTK's gboolean; I've left the platform booleans in places they _have_ to be for the platform APIs to work right, but variables only used by my own code have been converted wherever I found them. In a few places there are int values that look very like booleans in _most_ of the places they're used, but have a rarely-used third value, or a distinction between different nonzero values that most users don't care about. In these cases, I've _removed_ uses of 'true' and 'false' for the return values, to emphasise that there's something more subtle going on than a simple boolean answer: - the 'multisel' field in dialog.h's list box structure, for which the GTK front end in particular recognises a difference between 1 and 2 but nearly everything else treats as boolean - the 'urgent' parameter to plug_receive, where 1 vs 2 tells you something about the specific location of the urgent pointer, but most clients only care about 0 vs 'something nonzero' - the return value of wc_match, where -1 indicates a syntax error in the wildcard. - the return values from SSH-1 RSA-key loading functions, which use -1 for 'wrong passphrase' and 0 for all other failures (so any caller which already knows it's not loading an _encrypted private_ key can treat them as boolean) - term->esc_query, and the 'query' parameter in toggle_mode in terminal.c, which _usually_ hold 0 for ESC[123h or 1 for ESC[?123h, but can also hold -1 for some other intervening character that we don't support.

New abstraction 'Seat', to pass to backends. This is a new vtable-based abstraction which is passed to a backend in place of Frontend, and it implements only the subset of the Frontend functions needed by a backend. (Many other Frontend functions still exist, notably the wide range of things called by terminal.c providing platform-independent operations on the GUI terminal window.) The purpose of making it a vtable is that this opens up the possibility of creating a backend as an internal implementation detail of some other activity, by providing just that one backend with a custom Seat that implements the methods differently. For example, this refactoring should make it feasible to directly implement an SSH proxy type, aka the 'jump host' feature supported by OpenSSH, aka 'open a secondary SSH session in MAINCHAN_DIRECT_TCP mode, and then expose the main channel of that as the Socket for the primary connection'. (Which of course you can already do by spawning 'plink -nc' as a separate proxy process, but this would permit it in the _same_ process without anything getting confused.) I've centralised a full set of stub methods in misc.c for the new abstraction, which allows me to get rid of several annoying stubs in the previous code. Also, while I'm here, I've moved a lot of duplicated modalfatalbox() type functions from application main program files into wincons.c / uxcons.c, which I think saves duplication overall. (A minor visible effect is that the prefixes on those console-based fatal error messages will now be more consistent between applications.)

Remove the 'Frontend' type and replace it with a vtable. After the recent Seat and LogContext revamps, _nearly_ all the remaining uses of the type 'Frontend' were in terminal.c, which needs all sorts of interactions with the GUI window the terminal lives in, from the obvious (actually drawing text on the window, reading and writing the clipboard) to the obscure (minimising, maximising and moving the window in response to particular escape sequences). All of those functions are now provided by an abstraction called TermWin. The few remaining uses of Frontend after _that_ are internal to a particular platform directory, so as to spread the implementation of that particular kind of Frontend between multiple source files; so I've renamed all of those so that they take a more specifically named type that refers to the particular implementation rather than the general abstraction. So now the name 'Frontend' no longer exists in the code base at all, and everywhere one used to be used, it's completely clear whether it was operating in one of Frontend's three abstract roles (and if so, which), or whether it was specific to a particular implementation. Another type that's disappeared is 'Context', which used to be a typedef defined to something different on each platform, describing whatever short-lived resources were necessary to draw on the terminal window: the front end would provide a ready-made one when calling term_paint, and the terminal could request one with get_ctx/free_ctx if it wanted to do proactive window updates. Now that drawing context lives inside the TermWin itself, because there was never any need to have two of those contexts live at the same time. (Another minor API change is that the window-title functions - both reading and writing - have had a missing 'const' added to their char * parameters / return values.) I don't expect this change to enable any particularly interesting new functionality (in particular, I have no plans that need more than one implementation of TermWin in the same application).

Add a TermWin method to draw a 'trust sigil'. This is not yet used by anything, but the idea is that it'll be a graphic in the terminal window that can't be replicated by a server sending escape sequences, and hence can be used as a reliable indication that the text on a particular terminal line is generated by PuTTY itself and not passed through from the server. This will make it possible to detect a malicious server trying to mimic local prompts to trick you out of information that shouldn't be sent over the wire (such as private-key passphrases). The trust sigil I've picked is a small copy of the PuTTY icon, which is thematically nice (it can be read as if the PuTTY icon is the name of the speaker in a dialogue) and also convenient because we had that graphic available already on all platforms. (Though the contortions I had to go through to make the GTK 1 code draw it were quite annoying.) The trust sigil has the same dimensions as a CJK double-width character, i.e. it's 2 character cells wide by 1 high.

There's no obvious reason why one of those should be considered 'true' or 'positive' or 'success' - they're just indices - so I've left it as int. ssh_scp_recv had particularly confusing semantics for its previous int return value: its call sites used '<= 0' to check for error, but it never actually returned a negative number, just 0 or 1. Now the function and its call sites agree that it's a bool. In a couple of places I've renamed variables called 'ret', because I don't like that name any more - it's unclear whether it means the return value (in preparation) for the _containing_ function or the return value received from a subroutine call, and occasionally I've accidentally used the same variable for both and introduced a bug. So where one of those got in my way, I've renamed it to 'toret' or 'retd' (the latter short for 'returned') in line with my usual modern practice, but I haven't done a thorough job of finding all of them. Finally, one amusing side effect of doing this is that I've had to separate quite a few chained assignments. It used to be perfectly fine to write 'a = b = c = TRUE' when a,b,c were int and TRUE was just a the 'true' defined by stdbool.h, that idiom provokes a warning from gcc: 'suggest parentheses around assignment used as truth value'!

Remove the 'Frontend' type and replace it with a vtable. After the recent Seat and LogContext revamps, _nearly_ all the remaining uses of the type 'Frontend' were in terminal.c, which needs all sorts of interactions with the GUI window the terminal lives in, from the obvious (actually drawing text on the window, reading and writing the clipboard) to the obscure (minimising, maximising and moving the window in response to particular escape sequences). All of those functions are now provided by an abstraction called TermWin. The few remaining uses of Frontend after _that_ are internal to a particular platform directory, so as to spread the implementation of that particular kind of Frontend between multiple source files; so I've renamed all of those so that they take a more specifically named type that refers to the particular implementation rather than the general abstraction. So now the name 'Frontend' no longer exists in the code base at all, and everywhere one used to be used, it's completely clear whether it was operating in one of Frontend's three abstract roles (and if so, which), or whether it was specific to a particular implementation. Another type that's disappeared is 'Context', which used to be a typedef defined to something different on each platform, describing whatever short-lived resources were necessary to draw on the terminal window: the front end would provide a ready-made one when calling term_paint, and the terminal could request one with get_ctx/free_ctx if it wanted to do proactive window updates. Now that drawing context lives inside the TermWin itself, because there was never any need to have two of those contexts live at the same time. (Another minor API change is that the window-title functions - both reading and writing - have had a missing 'const' added to their char * parameters / return values.) I don't expect this change to enable any particularly interesting new functionality (in particular, I have no plans that need more than one implementation of TermWin in the same application).

Convert a lot of 'int' variables to 'bool'. My normal habit these days, in new code, is to treat int and bool as _almost_ completely separate types. I'm still willing to use C's implicit test for zero on an integer (e.g. 'if (!blob.len)' is fine, no need to spell it out as blob.len != 0), but generally, if a variable is going to be conceptually a boolean, I like to declare it bool and assign to it using 'true' or 'false' rather than 0 or 1. PuTTY is an exception, because it predates the C99 bool, and I've stuck to its existing coding style even when adding new code to it. But it's been annoying me more and more, so now that I've decided C99 bool is an acceptable thing to require from our toolchain in the first place, here's a quite thorough trawl through the source doing 'boolification'. Many variables and function parameters are now typed as bool rather than int; many assignments of 0 or 1 to those variables are now spelled 'true' or 'false'. I managed this thorough conversion with the help of a custom clang plugin that I wrote to trawl the AST and apply heuristics to point out where things might want changing. So I've even managed to do a decent job on parts of the code I haven't looked at in years! To make the plugin's work easier, I pushed platform front ends generally in the direction of using standard 'bool' in preference to platform-specific boolean types like Windows BOOL or GTK's gboolean; I've left the platform booleans in places they _have_ to be for the platform APIs to work right, but variables only used by my own code have been converted wherever I found them. In a few places there are int values that look very like booleans in _most_ of the places they're used, but have a rarely-used third value, or a distinction between different nonzero values that most users don't care about. In these cases, I've _removed_ uses of 'true' and 'false' for the return values, to emphasise that there's something more subtle going on than a simple boolean answer: - the 'multisel' field in dialog.h's list box structure, for which the GTK front end in particular recognises a difference between 1 and 2 but nearly everything else treats as boolean - the 'urgent' parameter to plug_receive, where 1 vs 2 tells you something about the specific location of the urgent pointer, but most clients only care about 0 vs 'something nonzero' - the return value of wc_match, where -1 indicates a syntax error in the wildcard. - the return values from SSH-1 RSA-key loading functions, which use -1 for 'wrong passphrase' and 0 for all other failures (so any caller which already knows it's not loading an _encrypted private_ key can treat them as boolean) - term->esc_query, and the 'query' parameter in toggle_mode in terminal.c, which _usually_ hold 0 for ESC[123h or 1 for ESC[?123h, but can also hold -1 for some other intervening character that we don't support.

static void wintw_set_zorder(TermWin *, bool top);
Centralise palette setup into terminal.c. Now terminal.c makes nearly all the decisions about what the colour palette should actually contain: it does the job of reading the GUI-configurable colours out of Conf, and also the job of making up the rest of the xterm-256 palette. The only exception is that TermWin can provide a method to override some of the default colours, which on Windows is used to implement the 'Use system colours' config option. This saves code overall, partly because the front ends don't have to be able to send palette data back to the Terminal any more (the Terminal keeps the master copy and can answer palette-query escape sequences from its own knowledge), and also because now there's only one copy of the xterm-256 palette setup code (previously gtkwin.c and window.c each had their own version of it). In this rewrite, I've also introduced a multi-layered storage system for the palette data in Terminal. One layer contains the palette information derived from Conf; the next contains platform overrides (currently just Windows's 'Use system colours'); the last one contains overrides set by escape sequences in the middle of the session. The topmost two layers can each _conditionally_ override the ones below. As a result, if a server-side application manually resets (say) the default fg and bg colours in mid-session to something that works well in a particular application, those changes won't be wiped out by a change in the Windows system colours or the Conf, which they would have been before. Instead, changes in Conf or the system colours alter the lower layers of the structure, but then when palette_rebuild is called, the upper layer continues to override them, until a palette reset (ESC]R) or terminal reset (e.g. ESC c) removes those upper-layer changes. This seems like a more consistent strategy, in that the same set of configuration settings will produce the same end result regardless of what order they were applied in. The palette-related methods in TermWin have had a total rework. palette_get and palette_reset are both gone; palette_set can now set a contiguous range of colours in one go; and the new palette_get_overrides replaces window.c's old systopalette().

Change vtable defs to use C99 designated initialisers. This is a sweeping change applied across the whole code base by a spot of Emacs Lisp. Now, everywhere I declare a vtable filled with function pointers (and the occasional const data member), all the members of the vtable structure are initialised by name using the '.fieldname = value' syntax introduced in C99. We were already using this syntax for a handful of things in the new key-generation progress report system, so it's not new to the code base as a whole. The advantage is that now, when a vtable only declares a subset of the available fields, I can initialise the rest to NULL or zero just by leaving them out. This is most dramatic in a couple of the outlying vtables in things like psocks (which has a ConnectionLayerVtable containing only one non-NULL method), but less dramatically, it means that the new 'flags' field in BackendVtable can be completely left out of every backend definition except for the SUPDUP one which defines it to a nonzero value. Similarly, the test_for_upstream method only used by SSH doesn't have to be mentioned in the rest of the backends; network Plugs for listening sockets don't have to explicitly null out 'receive' and 'sent', and vice versa for 'accepting', and so on. While I'm at it, I've normalised the declarations so they don't use the unnecessarily verbose 'struct' keyword. Also a handful of them weren't const; now they are.

This is most dramatic in a couple of the outlying vtables in things like psocks (which has a ConnectionLayerVtable containing only one non-NULL method), but less dramatically, it means that the new 'flags' field in BackendVtable can be completely left out of every backend definition except for the SUPDUP one which defines it to a nonzero value. Similarly, the test_for_upstream method only used by SSH doesn't have to be mentioned in the rest of the backends; network Plugs for listening sockets don't have to explicitly null out 'receive' and 'sent', and vice versa for 'accepting', and so on. While I'm at it, I've normalised the declarations so they don't use the unnecessarily verbose 'struct' keyword. Also a handful of them weren't const; now they are.

Centralise palette setup into terminal.c. Now terminal.c makes nearly all the decisions about what the colour palette should actually contain: it does the job of reading the GUI-configurable colours out of Conf, and also the job of making up the rest of the xterm-256 palette. The only exception is that TermWin can provide a method to override some of the default colours, which on Windows is used to implement the 'Use system colours' config option. This saves code overall, partly because the front ends don't have to be able to send palette data back to the Terminal any more (the Terminal keeps the master copy and can answer palette-query escape sequences from its own knowledge), and also because now there's only one copy of the xterm-256 palette setup code (previously gtkwin.c and window.c each had their own version of it). In this rewrite, I've also introduced a multi-layered storage system for the palette data in Terminal. One layer contains the palette information derived from Conf; the next contains platform overrides (currently just Windows's 'Use system colours'); the last one contains overrides set by escape sequences in the middle of the session. The topmost two layers can each _conditionally_ override the ones below. As a result, if a server-side application manually resets (say) the default fg and bg colours in mid-session to something that works well in a particular application, those changes won't be wiped out by a change in the Windows system colours or the Conf, which they would have been before. Instead, changes in Conf or the system colours alter the lower layers of the structure, but then when palette_rebuild is called, the upper layer continues to override them, until a palette reset (ESC]R) or terminal reset (e.g. ESC c) removes those upper-layer changes. This seems like a more consistent strategy, in that the same set of configuration settings will produce the same end result regardless of what order they were applied in. The palette-related methods in TermWin have had a total rework. palette_get and palette_reset are both gone; palette_set can now set a contiguous range of colours in one go; and the new palette_get_overrides replaces window.c's old systopalette().

Remove the 'Frontend' type and replace it with a vtable. After the recent Seat and LogContext revamps, _nearly_ all the remaining uses of the type 'Frontend' were in terminal.c, which needs all sorts of interactions with the GUI window the terminal lives in, from the obvious (actually drawing text on the window, reading and writing the clipboard) to the obscure (minimising, maximising and moving the window in response to particular escape sequences). All of those functions are now provided by an abstraction called TermWin. The few remaining uses of Frontend after _that_ are internal to a particular platform directory, so as to spread the implementation of that particular kind of Frontend between multiple source files; so I've renamed all of those so that they take a more specifically named type that refers to the particular implementation rather than the general abstraction. So now the name 'Frontend' no longer exists in the code base at all, and everywhere one used to be used, it's completely clear whether it was operating in one of Frontend's three abstract roles (and if so, which), or whether it was specific to a particular implementation. Another type that's disappeared is 'Context', which used to be a typedef defined to something different on each platform, describing whatever short-lived resources were necessary to draw on the terminal window: the front end would provide a ready-made one when calling term_paint, and the terminal could request one with get_ctx/free_ctx if it wanted to do proactive window updates. Now that drawing context lives inside the TermWin itself, because there was never any need to have two of those contexts live at the same time. (Another minor API change is that the window-title functions - both reading and writing - have had a missing 'const' added to their char * parameters / return values.) I don't expect this change to enable any particularly interesting new functionality (in particular, I have no plans that need more than one implementation of TermWin in the same application). But it completes the tidying-up that began with the Seat and LogContext rework.

Add a TermWin method to draw a 'trust sigil'. This is not yet used by anything, but the idea is that it'll be a graphic in the terminal window that can't be replicated by a server sending escape sequences, and hence can be used as a reliable indication that the text on a particular terminal line is generated by PuTTY itself and not passed through from the server. This will make it possible to detect a malicious server trying to mimic local prompts to trick you out of information that shouldn't be sent over the wire (such as private-key passphrases). The trust sigil I've picked is a small copy of the PuTTY icon, which is thematically nice (it can be read as if the PuTTY icon is the name of the speaker in a dialogue) and also convenient because we had that graphic available already on all platforms. (Though the contortions I had to go through to make the GTK 1 code draw it were quite annoying.) The trust sigil has the same dimensions as a CJK double-width character, i.e. it's 2 character cells wide by 1 high.

Convert a lot of 'int' variables to 'bool'. My normal habit these days, in new code, is to treat int and bool as _almost_ completely separate types. I'm still willing to use C's implicit test for zero on an integer (e.g. 'if (!blob.len)' is fine, no need to spell it out as blob.len != 0), but generally, if a variable is going to be conceptually a boolean, I like to declare it bool and assign to it using 'true' or 'false' rather than 0 or 1. PuTTY is an exception, because it predates the C99 bool, and I've stuck to its existing coding style even when adding new code to it. But it's been annoying me more and more, so now that I've decided C99 bool is an acceptable thing to require from our toolchain in the first place, here's a quite thorough trawl through the source doing 'boolification'. Many variables and function parameters are now typed as bool rather than int; many assignments of 0 or 1 to those variables are now spelled 'true' or 'false'. I managed this thorough conversion with the help of a custom clang plugin that I wrote to trawl the AST and apply heuristics to point out where things might want changing. So I've even managed to do a decent job on parts of the code I haven't looked at in years! To make the plugin's work easier, I pushed platform front ends generally in the direction of using standard 'bool' in preference to platform-specific boolean types like Windows BOOL or GTK's gboolean; I've left the platform booleans in places they _have_ to be for the platform APIs to work right, but variables only used by my own code have been converted wherever I found them. In a few places there are int values that look very like booleans in _most_ of the places they're used, but have a rarely-used third value, or a distinction between different nonzero values that most users don't care about. In these cases, I've _removed_ uses of 'true' and 'false' for the return values, to emphasise that there's something more subtle going on than a simple boolean answer: - the 'multisel' field in dialog.h's list box structure, for which the GTK front end in particular recognises a difference between 1 and 2 but nearly everything else treats as boolean - the 'urgent' parameter to plug_receive, where 1 vs 2 tells you something about the specific location of the urgent pointer, but most clients only care about 0 vs 'something nonzero' - the return value of wc_match, where -1 indicates a syntax error in the wildcard. - the return values from SSH-1 RSA-key loading functions, which use -1 for 'wrong passphrase' and 0 for all other failures (so any caller which already knows it's not loading an _encrypted private_ key can treat them as boolean) - term->esc_query, and the 'query' parameter in toggle_mode in terminal.c, which _usually_ hold 0 for ESC[123h or 1 for ESC[?123h, but can also hold -1 for some other intervening character that we don't support. In a few places there's an integer that I haven't turned into a bool even though it really _can_ only take values 0 or 1 (and, as above, tried to make the call sites consistent in not calling those values true and false), on the grounds that I thought it would make it more confusing to imply that the 0 value was in some sense 'negative' or bad and the 1 positive or good: - the return value of plug_accepting uses the POSIXish convention of 0=success and nonzero=error; I think if I made it bool then I'd also want to reverse its sense, and that's a job for a separate piece of work. - the 'screen' parameter to lineptr() in terminal.c, where 0 and 1 represent the default and alternate screens. There's no obvious reason why one of those should be considered 'true' or 'positive' or 'success' - they're just indices - so I've left it as int. ssh_scp_recv had particularly confusing semantics for its previous int return value: its call sites used '<= 0' to check for error, but it never actually returned a negative number, just 0 or 1. Now the function and its call sites agree that it's a bool. In a couple of places I've renamed variables called 'ret', because I don't like that name any more - it's unclear whether it means the return value (in preparation) for the _containing_ function or the return value received from a subroutine call, and occasionally I've accidentally used the same variable for both and introduced a bug. So where one of those got in my way, I've renamed it to 'toret' or 'retd' (the latter short for 'returned') in line with my usual modern practice, but I haven't done a thorough job of finding all of them. Finally, one amusing side effect of doing this is that I've had to separate quite a few chained assignments. It used to be perfectly fine to write 'a = b = c = TRUE' when a,b,c were int and TRUE was just a the 'true' defined by stdbool.h, that idiom provokes a warning from gcc: 'suggest parentheses around assignment used as truth value'!

Implement connection sharing between instances of PuTTY. The basic strategy is described at the top of the new source file sshshare.c. In very brief: an 'upstream' PuTTY opens a Unix-domain socket or Windows named pipe, and listens for connections from other PuTTYs wanting to run sessions on the same server. The protocol spoken down that socket/pipe is essentially the bare ssh-connection protocol, using a trivial binary packet protocol with no encryption, and the upstream has to do some fiddly transformations that I've been referring to as 'channel-number NAT' to avoid resource clashes between the sessions it's managing. This is quite different from OpenSSH's approach of using the Unix- domain socket as a means of passing file descriptors around; the main reason for that is that fd-passing is Unix-specific but this system has to work on Windows too. However, there are additional advantages, such as making it easy for each downstream PuTTY to run its own independent set of port and X11 forwardings (though the method for making the latter work is quite painful). Sharing is off by default, but configuration is intended to be very easy in the normal case - just tick one box in the SSH config panel and everything else happens automatically.

{
New abstraction 'Seat', to pass to backends. This is a new vtable-based abstraction which is passed to a backend in place of Frontend, and it implements only the subset of the Frontend functions needed by a backend. (Many other Frontend functions still exist, notably the wide range of things called by terminal.c providing platform-independent operations on the GUI terminal window.) The purpose of making it a vtable is that this opens up the possibility of creating a backend as an internal implementation detail of some other activity, by providing just that one backend with a custom Seat that implements the methods differently. For example, this refactoring should make it feasible to directly implement an SSH proxy type, aka the 'jump host' feature supported by OpenSSH, aka 'open a secondary SSH session in MAINCHAN_DIRECT_TCP mode, and then expose the main channel of that as the Socket for the primary connection'. (Which of course you can already do by spawning 'plink -nc' as a separate proxy process, but this would permit it in the _same_ process without anything getting confused.) I've centralised a full set of stub methods in misc.c for the new abstraction, which allows me to get rid of several annoying stubs in the previous code. Also, while I'm here, I've moved a lot of duplicated modalfatalbox() type functions from application main program files into wincons.c / uxcons.c, which I think saves duplication overall. (A minor visible effect is that the prefixes on those console-based fatal error messages will now be more consistent between applications.)

All the other changes of behaviour needed between those two contexts are handled by providing reconfigurable methods in the Seat vtable; this one is no different.

Convert a lot of 'int' variables to 'bool'. My normal habit these days, in new code, is to treat int and bool as _almost_ completely separate types. I'm still willing to use C's implicit test for zero on an integer (e.g. 'if (!blob.len)' is fine, no need to spell it out as blob.len != 0), but generally, if a variable is going to be conceptually a boolean, I like to declare it bool and assign to it using 'true' or 'false' rather than 0 or 1. PuTTY is an exception, because it predates the C99 bool, and I've stuck to its existing coding style even when adding new code to it. But it's been annoying me more and more, so now that I've decided C99 bool is an acceptable thing to require from our toolchain in the first place, here's a quite thorough trawl through the source doing 'boolification'. Many variables and function parameters are now typed as bool rather than int; many assignments of 0 or 1 to those variables are now spelled 'true' or 'false'. I managed this thorough conversion with the help of a custom clang plugin that I wrote to trawl the AST and apply heuristics to point out where things might want changing. So I've even managed to do a decent job on parts of the code I haven't looked at in years! To make the plugin's work easier, I pushed platform front ends generally in the direction of using standard 'bool' in preference to platform-specific boolean types like Windows BOOL or GTK's gboolean; I've left the platform booleans in places they _have_ to be for the platform APIs to work right, but variables only used by my own code have been converted wherever I found them. In a few places there are int values that look very like booleans in _most_ of the places they're used, but have a rarely-used third value, or a distinction between different nonzero values that most users don't care about. In these cases, I've _removed_ uses of 'true' and 'false' for the return values, to emphasise that there's something more subtle going on than a simple boolean answer: - the 'multisel' field in dialog.h's list box structure, for which the GTK front end in particular recognises a difference between 1 and 2 but nearly everything else treats as boolean - the 'urgent' parameter to plug_receive, where 1 vs 2 tells you something about the specific location of the urgent pointer, but most clients only care about 0 vs 'something nonzero' - the return value of wc_match, where -1 indicates a syntax error in the wildcard. - the return values from SSH-1 RSA-key loading functions, which use -1 for 'wrong passphrase' and 0 for all other failures (so any caller which already knows it's not loading an _encrypted private_ key can treat them as boolean) - term->esc_query, and the 'query' parameter in toggle_mode in terminal.c, which _usually_ hold 0 for ESC[123h or 1 for ESC[?123h, but can also hold -1 for some other intervening character that we don't support. In a few places there's an integer that I haven't turned into a bool even though it really _can_ only take values 0 or 1 (and, as above, tried to make the call sites consistent in not calling those values true and false), on the grounds that I thought it would make it more confusing to imply that the 0 value was in some sense 'negative' or bad and the 1 positive or good: - the return value of plug_accepting uses the POSIXish convention of 0=success and nonzero=error; I think if I made it bool then I'd also want to reverse its sense, and that's a job for a separate piece of work. - the 'screen' parameter to lineptr() in terminal.c, where 0 and 1 represent the default and alternate screens. There's no obvious reason why one of those should be considered 'true' or 'positive' or 'success' - they're just indices - so I've left it as int. ssh_scp_recv had particularly confusing semantics for its previous int return value: its call sites used '<= 0' to check for error, but it never actually returned a negative number, just 0 or 1. Now the function and its call sites agree that it's a bool. In a couple of places I've renamed variables called 'ret', because I don't like that name any more - it's unclear whether it means the return value (in preparation) for the _containing_ function or the return value received from a subroutine call, and occasionally I've accidentally used the same variable for both and introduced a bug. So where one of those got in my way, I've renamed it to 'toret' or 'retd' (the latter short for 'returned') in line with my usual modern practice, but I haven't done a thorough job of finding all of them. Finally, one amusing side effect of doing this is that I've had to separate quite a few chained assignments. It used to be perfectly fine to write 'a = b = c = TRUE' when a,b,c were int and TRUE was just a the 'true' defined by stdbool.h, that idiom provokes a warning from gcc: 'suggest parentheses around assignment used as truth value'!

New abstraction 'Seat', to pass to backends. This is a new vtable-based abstraction which is passed to a backend in place of Frontend, and it implements only the subset of the Frontend functions needed by a backend. (Many other Frontend functions still exist, notably the wide range of things called by terminal.c providing platform-independent operations on the GUI terminal window.) The purpose of making it a vtable is that this opens up the possibility of creating a backend as an internal implementation detail of some other activity, by providing just that one backend with a custom Seat that implements the methods differently. For example, this refactoring should make it feasible to directly implement an SSH proxy type, aka the 'jump host' feature supported by OpenSSH, aka 'open a secondary SSH session in MAINCHAN_DIRECT_TCP mode, and then expose the main channel of that as the Socket for the primary connection'. (Which of course you can already do by spawning 'plink -nc' as a separate proxy process, but this would permit it in the _same_ process without anything getting confused.) I've centralised a full set of stub methods in misc.c for the new abstraction, which allows me to get rid of several annoying stubs in the previous code. Also, while I'm here, I've moved a lot of duplicated modalfatalbox() type functions from application main program files into wincons.c / uxcons.c, which I think saves duplication overall.

Flip direction of window pos/size queries. Similarly to other recent changes, the frontend now proactively keeps Terminal up to date with the current position and size of the terminal window, so that escape-sequence queries can be answered immediately from the Terminal's own internal data structures without needing a call back to the frontend. Mostly this has let me remove explicit window-system API calls that retrieve the window position and size, in favour of having the front ends listen for WM_MOVE / WM_SIZE / ConfigureNotify events and track the position and size that way. One exception is that the window pixel size is still requested by Seat via a callback, to put in the wire-encoded termios settings. That won't be happening very much, so I'm leaving it this way round for the moment.

static const SeatVtable win_seat_vt = {
Change vtable defs to use C99 designated initialisers. This is a sweeping change applied across the whole code base by a spot of Emacs Lisp. Now, everywhere I declare a vtable filled with function pointers (and the occasional const data member), all the members of the vtable structure are initialised by name using the '.fieldname = value' syntax introduced in C99. We were already using this syntax for a handful of things in the new key-generation progress report system, so it's not new to the code base as a whole. The advantage is that now, when a vtable only declares a subset of the available fields, I can initialise the rest to NULL or zero just by leaving them out. This is most dramatic in a couple of the outlying vtables in things like psocks (which has a ConnectionLayerVtable containing only one non-NULL method), but less dramatically, it means that the new 'flags' field in BackendVtable can be completely left out of every backend definition except for the SUPDUP one which defines it to a nonzero value. Similarly, the test_for_upstream method only used by SSH doesn't have to be mentioned in the rest of the backends; network Plugs for listening sockets don't have to explicitly null out 'receive' and 'sent', and vice versa for 'accepting', and so on. While I'm at it, I've normalised the declarations so they don't use the unnecessarily verbose 'struct' keyword. Also a handful of them weren't const; now they are.

GUI PuTTY: stop using the global 'hwnd'. This was the difficult part of cleaning up that global variable. The main Windows PuTTY GUI is split between source files, so that _does_ actually need to refer to the main window from multiple places. But all the places where windlg.c needed to use 'hwnd' are seat methods, so they were already receiving a Seat pointer as a parameter. In other words, the methods of the Windows GUI Seat were already split between source files. So it seems only fair that they should be able to share knowledge of the seat's data as well. Hence, I've created a small 'WinGuiSeat' structure which both window.c and windlg.c can see the layout of, and put the main terminal window handle in there. Then the seat methods implemented in windlg.c, like win_seat_verify_ssh_host_key, can use container_of to turn the Seat pointer parameter back into the address of that structure, just as the methods in window.c can do (even though they currently don't need to). (Who knows: now that it _exists_, perhaps that structure can be gradually expanded in future to turn it into a proper encapsulation of all the Windows frontend's state, like we should have had all along...) I've also moved the Windows GUI LogPolicy implementation into the same object (i.e. WinGuiSeat implements both traits at once). That allows win_gui_logging_error to recover the same WinGuiSeat from its input LogPolicy pointer, which means it can get from there to the Seat facet of the same object, so that I don't need the extern variable 'win_seat' any more either.

Move all window-title management into Terminal. Previously, window title management happened in a bipartisan sort of way: front ends would choose their initial window title once they knew what host name they were connecting to, but then Terminal would override that later if the server set the window title by escape sequences. Now it's all done the same way round: the Terminal object is always where titles are invented, and they only propagate in one direction, from the Terminal to the TermWin. This allows us to avoid duplicating in multiple front ends the logic for what the initial window title should be. The frontend just has to make one initial call to term_setup_window_titles, to tell the terminal what hostname should go in the default title (if the Conf doesn't override even that). Thereafter, all it has to do is respond to the TermWin title-setting methods. Similarly, the logic that handles window-title changes as a result of the Change Settings dialog is also centralised into terminal.c. This involved introducing an extra term_pre_reconfig() call that each frontend can call to modify the Conf that will be used for the GUI configurer; that's where the code now lives that copies the current window title into there. (This also means that GTK PuTTY now behaves consistently with Windows PuTTY on that point; GTK's previous behaviour was less well thought out.) It also means there's no longer any need for Terminal to talk to the front end when a remote query wants to _find out_ the window title: the Terminal knows the answer already. So TermWin's get_title method can go.

While I'm modernising the rest of the code, this seems like a good time to turn that into the same more or less type-safe and less cumbersome system as I'm using for other parts of the code, such as Socket, Plug, BinaryPacketProtocol and so forth: the Backend structure contains a vtable pointer, and a system of macro wrappers handles dispatching through that vtable.

GUI PuTTY: stop using the global 'hwnd'. This was the difficult part of cleaning up that global variable. The main Windows PuTTY GUI is split between source files, so that _does_ actually need to refer to the main window from multiple places. But all the places where windlg.c needed to use 'hwnd' are seat methods, so they were already receiving a Seat pointer as a parameter. In other words, the methods of the Windows GUI Seat were already split between source files. So it seems only fair that they should be able to share knowledge of the seat's data as well. Hence, I've created a small 'WinGuiSeat' structure which both window.c and windlg.c can see the layout of, and put the main terminal window handle in there. Then the seat methods implemented in windlg.c, like win_seat_verify_ssh_host_key, can use container_of to turn the Seat pointer parameter back into the address of that structure, just as the methods in window.c can do (even though they currently don't need to). (Who knows: now that it _exists_, perhaps that structure can be gradually expanded in future to turn it into a proper encapsulation of all the Windows frontend's state, like we should have had all along...) I've also moved the Windows GUI LogPolicy implementation into the same object (i.e. WinGuiSeat implements both traits at once). That allows win_gui_logging_error to recover the same WinGuiSeat from its input LogPolicy pointer, which means it can get from there to the Seat facet of the same object, so that I don't need the extern variable 'win_seat' any more either.

Make cmdline_tooltype a const int. Another ugly mutable global variable gone: now, instead of this variable being defined in cmdline.c and written to by everyone's main(), it's defined _alongside_ everyone's main() as a constant, and cmdline.c just refers to it. A bonus is that now nocmdline.c doesn't have to define it anyway for tools that don't use cmdline.c. But mostly, it didn't need to be mutable, so better for it not to be. While I'm at it, I've also fiddled with the bit flags that go in it, to define their values automatically using a list macro instead of manually specifying each one to be a different power of 2.

Remove remaining uses of the GLOBAL macro. We now have no remaining things in header files that switch from being a declaration to a definition depending on an awkward #define at the point of including that header. There are still a few mutable variables with external linkage, but at least now each one is defined in a specific source file file appropriate to its purpose and context. The remaining globals as of this commit were: - 'logctx' and 'term', which never needed to be globals in the first place, because they were never actually shared between source files. Now 'term' is just a static in window.c, and 'logctx' is a static in each of that and winplink.c. - 'hinst', which still has external linkage, but is now defined separately in each source file that sets it up (i.e. those with a WinMain) - osMajorVersion, osMinorVersion and osPlatformId, whose definitions now live in winmisc.c alongside the code which sets them up. (Actually they were defined there all along, it turns out, but every toolchain I've built with has commoned them together with the version defined by the GLOBAL in the header.) - 'hwnd', which nothing was actually _using_ any more after previous commits, so all this commit had to do was delete it.

Lock down the search path for Windows DLL loading. At least on systems providing SetDefaultDllDirectories, this should stop PuTTY from being willing to load DLLs from its containing directory - which makes no difference when it's been properly installed (in which case the application dir contains no DLLs anyway), but does if it's being run from somewhere uncontrolled like a browser downloads directory. Preliminary testing suggests that this shouldn't break any existing deliberate use of DLLs, including GSSAPI providers.

Created a shiny new abstraction for the socket handling. Has many advantages: - protocol modules can call sk_write() without having to worry about writes blocking, because blocking writes are handled in the abstraction layer and retried later. - `Lost connection while sending' is a thing of the past. - <winsock.h> is no longer needed in most modules, because "putty.h" doesn't have to declare `SOCKET' variables any more, only the abstracted `Socket' type. - select()-equivalent between multiple sockets will now be handled sensibly, which opens the way for things like SSH port forwarding.

Now the entire list of remaining DLLs that PuTTY links against at load time is a subset of the Win10 known DLLs list, so that _should_ mean that everything we load before we've deployed our own defence (SetDefaultDllDirectories) is defended against for us by Windows itself.

It explicitly tries to load HHCTRL.OCX and use GetProcAddress, meaning that it _should_ still work correctly on pre-HTML-Help platforms, falling gracefully back to WinHelp, but although I tested this by temporarily renaming my own HHCTRL.OCX I haven't yet been able to test it on a real HTML-Help-free platform. Also in this checkin: a new .but file and docs makefile changes to make it convenient to build the sources for a .CHM.

Post-release destabilisation! Completely remove the struct type 'Config' in putty.h, which stores all PuTTY's settings and includes an arbitrary length limit on every single one of those settings which is stored in string form. In place of it is 'Conf', an opaque data type everywhere outside the new file conf.c, which stores a list of (key, value) pairs in which every key contains an integer identifying a configuration setting, and for some of those integers the key also contains extra parts (so that, for instance, CONF_environmt is a string-to-string mapping). Everywhere that a Config was previously used, a Conf is now; everywhere there was a Config structure copy, conf_copy() is called; every lookup, adjustment, load and save operation on a Config has been rewritten; and there's a mechanism for serialising a Conf into a binary blob and back for use with Duplicate Session. User-visible effects of this change _should_ be minimal, though I don't doubt I've introduced one or two bugs here and there which will eventually be found. The _intended_ visible effects of this change are that all arbitrary limits on configuration strings and lists (e.g. limit on number of port forwardings) should now disappear; that list boxes in the configuration will now be displayed in a sorted order rather than the arbitrary order in which they were added to the list (since the underlying data structure is now a sorted tree234 rather than an ad-hoc comma-separated string); and one more specific change, which is that local and dynamic port forwardings on the same port number are now mutually exclusive in the configuration (putting 'D' in the key rather than the value was a mistake in the first place). One other reorganisation as a result of this is that I've moved all the dialog.c standard handlers (dlg_stdeditbox_handler and friends) out into config.c, because I can't really justify calling them generic any more. When they took a pointer to an arbitrary structure type and the offset of a field within that structure, they were independent of whether that structure was a Config or something completely different, but now they really do expect to talk to a Conf, which can _only_ be used for PuTTY configuration, so I've renamed them all things like conf_editbox_handler and moved them out of the nominally independent dialog-box management module into the PuTTY-specific config.c.

char *p;
Convert a lot of 'int' variables to 'bool'. My normal habit these days, in new code, is to treat int and bool as _almost_ completely separate types. I'm still willing to use C's implicit test for zero on an integer (e.g. 'if (!blob.len)' is fine, no need to spell it out as blob.len != 0), but generally, if a variable is going to be conceptually a boolean, I like to declare it bool and assign to it using 'true' or 'false' rather than 0 or 1. PuTTY is an exception, because it predates the C99 bool, and I've stuck to its existing coding style even when adding new code to it. But it's been annoying me more and more, so now that I've decided C99 bool is an acceptable thing to require from our toolchain in the first place, here's a quite thorough trawl through the source doing 'boolification'. Many variables and function parameters are now typed as bool rather than int; many assignments of 0 or 1 to those variables are now spelled 'true' or 'false'. I managed this thorough conversion with the help of a custom clang plugin that I wrote to trawl the AST and apply heuristics to point out where things might want changing. So I've even managed to do a decent job on parts of the code I haven't looked at in years! To make the plugin's work easier, I pushed platform front ends generally in the direction of using standard 'bool' in preference to platform-specific boolean types like Windows BOOL or GTK's gboolean; I've left the platform booleans in places they _have_ to be for the platform APIs to work right, but variables only used by my own code have been converted wherever I found them. In a few places there are int values that look very like booleans in _most_ of the places they're used, but have a rarely-used third value, or a distinction between different nonzero values that most users don't care about. In these cases, I've _removed_ uses of 'true' and 'false' for the return values, to emphasise that there's something more subtle going on than a simple boolean answer: - the 'multisel' field in dialog.h's list box structure, for which the GTK front end in particular recognises a difference between 1 and 2 but nearly everything else treats as boolean - the 'urgent' parameter to plug_receive, where 1 vs 2 tells you something about the specific location of the urgent pointer, but most clients only care about 0 vs 'something nonzero' - the return value of wc_match, where -1 indicates a syntax error in the wildcard. - the return values from SSH-1 RSA-key loading functions, which use -1 for 'wrong passphrase' and 0 for all other failures (so any caller which already knows it's not loading an _encrypted private_ key can treat them as boolean) - term->esc_query, and the 'query' parameter in toggle_mode in terminal.c, which _usually_ hold 0 for ESC[123h or 1 for ESC[?123h, but can also hold -1 for some other intervening character that we don't support. In a few places there's an integer that I haven't turned into a bool even though it really _can_ only take values 0 or 1 (and, as above, tried to make the call sites consistent in not calling those values true and false), on the grounds that I thought it would make it more confusing to imply that the 0 value was in some sense 'negative' or bad and the 1 positive or good: - the return value of plug_accepting uses the POSIXish convention of 0=success and nonzero=error; I think if I made it bool then I'd also want to reverse its sense, and that's a job for a separate piece of work. - the 'screen' parameter to lineptr() in terminal.c, where 0 and 1 represent the default and alternate screens. There's no obvious reason why one of those should be considered 'true' or 'positive' or 'success' - they're just indices - so I've left it as int. ssh_scp_recv had particularly confusing semantics for its previous int return value: its call sites used '<= 0' to check for error, but it never actually returned a negative number, just 0 or 1. Now the function and its call sites agree that it's a bool. In a couple of places I've renamed variables called 'ret', because I don't like that name any more - it's unclear whether it means the return value (in preparation) for the _containing_ function or the return value received from a subroutine call, and occasionally I've accidentally used the same variable for both and introduced a bug. So where one of those got in my way, I've renamed it to 'toret' or 'retd' (the latter short for 'returned') in line with my usual modern practice, but I haven't done a thorough job of finding all of them. Finally, one amusing side effect of doing this is that I've had to separate quite a few chained assignments. It used to be perfectly fine to write 'a = b = c = TRUE' when a,b,c were int and TRUE was just a the 'true' defined by stdbool.h, that idiom provokes a warning from gcc: 'suggest parentheses around assignment used as truth value'!

So there's no real need for them to be universally accessible via the awkward GLOBAL mechanism: they can be statics inside settings.c, with accessor functions that can set them. That was the last GLOBAL in putty.h, so I've removed the definition of the macro GLOBAL itself as well. There are still some GLOBALs in the Windows subdirectory, though.

Turn Backend into a sensible classoid. Nearly every part of the code that ever handles a full backend structure has historically done it using a pair of pointer variables, one pointing at a constant struct full of function pointers, and the other pointing to a 'void *' state object that's passed to each of those. While I'm modernising the rest of the code, this seems like a good time to turn that into the same more or less type-safe and less cumbersome system as I'm using for other parts of the code, such as Socket, Plug, BinaryPacketProtocol and so forth: the Backend structure contains a vtable pointer, and a system of macro wrappers handles dispatching through that vtable.

(Literally speaking, what we actually pass through to the sub-PuTTY's command line is not the "-restrict-acl" option itself, but a special prefix "&R", which has the same meaning but which lives in the special pre-argv-splitting command-line namespace like the magic options used for Duplicate Session and the old '@sessionname' prefix which the Saved Sessions submenu still uses. Otherwise, by the time we split up argv and recognised -restrict-acl, it would be too late to parse those other options.) One case in which PuTTY spawns a subprocess and this change _doesn't_ apply is when the subprocess is a proxy command which happens to be a Plink. Recognising Plink commands in that situation would be fragile and unreliable, and in any case if the user wants a proxy Plink to be ACL-restricted, they are in control of its exact command line so they can add -restrict-acl themselves.

While I'm at it, I've also taken the opportunity to remove all the trailing spaces from source lines (on the basis that git dislikes them, and is the only thing that seems to have a strong opinion one way or the other).

Centralise PuTTY and Plink's non-option argument handling. This is another piece of long-overdue refactoring similar to the recent commit e3796cb77. But where that one dealt with normalisation of stuff already stored _in_ a Conf by whatever means (including, in particular, handling a user typing 'username@host.name' into the Hostname box of the GUI session dialog box), this one deals with handling argv entries and putting them into the Conf. This isn't exactly a pure no-functional-change-at-all refactoring. On the other hand, it isn't a full-on cleanup that completely rationalises all the user-visible behaviour as well as the code structure. It's somewhere in between: I've preserved all the behaviour quirks that I could imagine a reason for having intended, but taken the opportunity to _not_ faithfully replicate anything I thought was clearly just a bug. So, for example, the following inconsistency is carefully preserved: the command 'plink -load session nextword' treats 'nextword' as a host name if the loaded session hasn't provided a hostname already, and otherwise treats 'nextword' as the remote command to execute on the already-specified remote host, but the same combination of arguments to GUI PuTTY will _always_ treat 'nextword' as a hostname, overriding a hostname (if any) in the saved session. That makes some sense to me because of the different shapes of the overall command lines. On the other hand, there are two behaviour changes I know of as a result of this commit: a third argument to GUI PuTTY (after a hostname and port) now provokes an error message instead of being silently ignored, and in Plink, if you combine a -P option (specifying a port number) with the historical comma-separated protocol selection prefix on the hostname argument (which I'd completely forgotten even existed until this piece of work), then the -P will now override the selected protocol's default port number, whereas previously the default port would win. For example, 'plink -P 12345 telnet,hostname' will now connect via Telnet to port 12345 instead of to port 23. There may be scope for removing or rethinking some of the command- line syntax quirks in the wake of this change. If we do decide to do anything like that, then hopefully having it all in one place will make it easier to remove or change things consistently across the tools.

Stop having a global Conf. It's now a static in the main source file of each application that uses it, and isn't accessible from any other source file unless the main one passes it by reference. In fact, there were almost no instances of the latter: only the config-box functions in windlg.c were using 'conf' by virtue of its globalness, and it's easy to make those take it as a parameter.

Revamp of command-line handling. Most command line options should now be processed in cmdline.c, which is called from all utilities (well, not Pageant or PuTTYgen). This should mean we get to standardise almost all options across almost all tools. Also one major change: `-load' is now the preferred option for loading a saved session in PuTTY proper. `@session' still works but is deprecated. [originally from svn r1799]

Factor out common pre-session-launch preparation. A more or less identical piece of code to sanitise the CONF_host string prior to session launch existed in Windows PuTTY and both Windows and Unix Plink. It's long past time it was centralised. While I'm here, I've added a couple of extra comments in the centralised version, including one that - unfortunately - tries _but fails_ to explain why a string of the form "host.name:1234" doesn't get the suffix moved into CONF_port the way "user@host" moves the prefix into CONF_username. Commit c1c1bc471 is the one I'm referring to in the comment, and unfortunately it has an unexplained one-liner log message from before I got into the habit of being usefully verbose.

Deglobalise the Unicode module. Despite all my grand plans, I've just done this the very simple way - bundle all the globals into a data structure and pass pointers around. One particularly ugly wart is that wc_to_mb now takes a pointer to this structure as an argument (optional, may be NULL, and unused in any Unicode layer that's even marginally less of a mess than the Windows one). I do need to do this properly at some point, but for now this should just about be adequate. As usual, the Mac port has not been updated. [originally from svn r2592]

Post-release destabilisation! Completely remove the struct type 'Config' in putty.h, which stores all PuTTY's settings and includes an arbitrary length limit on every single one of those settings which is stored in string form. In place of it is 'Conf', an opaque data type everywhere outside the new file conf.c, which stores a list of (key, value) pairs in which every key contains an integer identifying a configuration setting, and for some of those integers the key also contains extra parts (so that, for instance, CONF_environmt is a string-to-string mapping). Everywhere that a Config was previously used, a Conf is now; everywhere there was a Config structure copy, conf_copy() is called; every lookup, adjustment, load and save operation on a Config has been rewritten; and there's a mechanism for serialising a Conf into a binary blob and back for use with Duplicate Session. User-visible effects of this change _should_ be minimal, though I don't doubt I've introduced one or two bugs here and there which will eventually be found. The _intended_ visible effects of this change are that all arbitrary limits on configuration strings and lists (e.g. limit on number of port forwardings) should now disappear; that list boxes in the configuration will now be displayed in a sorted order rather than the arbitrary order in which they were added to the list (since the underlying data structure is now a sorted tree234 rather than an ad-hoc comma-separated string); and one more specific change, which is that local and dynamic port forwardings on the same port number are now mutually exclusive in the configuration (putting 'D' in the key rather than the value was a mistake in the first place). One other reorganisation as a result of this is that I've moved all the dialog.c standard handlers (dlg_stdeditbox_handler and friends) out into config.c, because I can't really justify calling them generic any more. When they took a pointer to an arbitrary structure type and the offset of a field within that structure, they were independent of whether that structure was a Config or something completely different, but now they really do expect to talk to a Conf, which can _only_ be used for PuTTY configuration, so I've renamed them all things like conf_editbox_handler and moved them out of the nominally independent dialog-box management module into the PuTTY-specific config.c.

GUI PuTTY: stop using the global 'hwnd'. This was the difficult part of cleaning up that global variable. The main Windows PuTTY GUI is split between source files, so that _does_ actually need to refer to the main window from multiple places. But all the places where windlg.c needed to use 'hwnd' are seat methods, so they were already receiving a Seat pointer as a parameter. In other words, the methods of the Windows GUI Seat were already split between source files. So it seems only fair that they should be able to share knowledge of the seat's data as well. Hence, I've created a small 'WinGuiSeat' structure which both window.c and windlg.c can see the layout of, and put the main terminal window handle in there. Then the seat methods implemented in windlg.c, like win_seat_verify_ssh_host_key, can use container_of to turn the Seat pointer parameter back into the address of that structure, just as the methods in window.c can do (even though they currently don't need to). (Who knows: now that it _exists_, perhaps that structure can be gradually expanded in future to turn it into a proper encapsulation of all the Windows frontend's state, like we should have had all along...) I've also moved the Windows GUI LogPolicy implementation into the same object (i.e. WinGuiSeat implements both traits at once). That allows win_gui_logging_error to recover the same WinGuiSeat from its input LogPolicy pointer, which means it can get from there to the Seat facet of the same object, so that I don't need the extern variable 'win_seat' any more either.

Centralise palette setup into terminal.c. Now terminal.c makes nearly all the decisions about what the colour palette should actually contain: it does the job of reading the GUI-configurable colours out of Conf, and also the job of making up the rest of the xterm-256 palette. The only exception is that TermWin can provide a method to override some of the default colours, which on Windows is used to implement the 'Use system colours' config option. This saves code overall, partly because the front ends don't have to be able to send palette data back to the Terminal any more (the Terminal keeps the master copy and can answer palette-query escape sequences from its own knowledge), and also because now there's only one copy of the xterm-256 palette setup code (previously gtkwin.c and window.c each had their own version of it). In this rewrite, I've also introduced a multi-layered storage system for the palette data in Terminal. One layer contains the palette information derived from Conf; the next contains platform overrides (currently just Windows's 'Use system colours'); the last one contains overrides set by escape sequences in the middle of the session. The topmost two layers can each _conditionally_ override the ones below. As a result, if a server-side application manually resets (say) the default fg and bg colours in mid-session to something that works well in a particular application, those changes won't be wiped out by a change in the Windows system colours or the Conf, which they would have been before. Instead, changes in Conf or the system colours alter the lower layers of the structure, but then when palette_rebuild is called, the upper layer continues to override them, until a palette reset (ESC]R) or terminal reset (e.g. ESC c) removes those upper-layer changes. This seems like a more consistent strategy, in that the same set of configuration settings will produce the same end result regardless of what order they were applied in. The palette-related methods in TermWin have had a total rework. palette_get and palette_reset are both gone; palette_set can now set a contiguous range of colours in one go; and the new palette_get_overrides replaces window.c's old systopalette().

Remove the 'Frontend' type and replace it with a vtable. After the recent Seat and LogContext revamps, _nearly_ all the remaining uses of the type 'Frontend' were in terminal.c, which needs all sorts of interactions with the GUI window the terminal lives in, from the obvious (actually drawing text on the window, reading and writing the clipboard) to the obscure (minimising, maximising and moving the window in response to particular escape sequences). All of those functions are now provided by an abstraction called TermWin. The few remaining uses of Frontend after _that_ are internal to a particular platform directory, so as to spread the implementation of that particular kind of Frontend between multiple source files; so I've renamed all of those so that they take a more specifically named type that refers to the particular implementation rather than the general abstraction. So now the name 'Frontend' no longer exists in the code base at all, and everywhere one used to be used, it's completely clear whether it was operating in one of Frontend's three abstract roles (and if so, which), or whether it was specific to a particular implementation. Another type that's disappeared is 'Context', which used to be a typedef defined to something different on each platform, describing whatever short-lived resources were necessary to draw on the terminal window: the front end would provide a ready-made one when calling term_paint, and the terminal could request one with get_ctx/free_ctx if it wanted to do proactive window updates. Now that drawing context lives inside the TermWin itself, because there was never any need to have two of those contexts live at the same time. (Another minor API change is that the window-title functions - both reading and writing - have had a missing 'const' added to their char * parameters / return values.) I don't expect this change to enable any particularly interesting new functionality (in particular, I have no plans that need more than one implementation of TermWin in the same application). But it completes the tidying-up that began with the Seat and LogContext rework.

Add GUI configuration for choice of clipboards. On all platforms, you can now configure which clipboard the mouse pastes from, which clipboard Ctrl-Ins and Shift-Ins access, and which Ctrl-Shift-C and Ctrl-Shift-V access. In each case, the options are: - nothing at all - a clipboard which is implicitly written by the act of mouse selection (the PRIMARY selection on X, CLIP_LOCAL everywhere else) - the standard clipboard written by explicit copy/paste UI actions (CLIPBOARD on X, the unique system clipboard elsewhere). Also, you can control whether selecting text with the mouse _also_ writes to the explicitly accessed clipboard. The wording of the various messages changes between platforms, but the basic UI shape is the same everywhere.

GUI PuTTY: stop using the global 'hwnd'. This was the difficult part of cleaning up that global variable. The main Windows PuTTY GUI is split between source files, so that _does_ actually need to refer to the main window from multiple places. But all the places where windlg.c needed to use 'hwnd' are seat methods, so they were already receiving a Seat pointer as a parameter. In other words, the methods of the Windows GUI Seat were already split between source files. So it seems only fair that they should be able to share knowledge of the seat's data as well. Hence, I've created a small 'WinGuiSeat' structure which both window.c and windlg.c can see the layout of, and put the main terminal window handle in there. Then the seat methods implemented in windlg.c, like win_seat_verify_ssh_host_key, can use container_of to turn the Seat pointer parameter back into the address of that structure, just as the methods in window.c can do (even though they currently don't need to). (Who knows: now that it _exists_, perhaps that structure can be gradually expanded in future to turn it into a proper encapsulation of all the Windows frontend's state, like we should have had all along...) I've also moved the Windows GUI LogPolicy implementation into the same object (i.e. WinGuiSeat implements both traits at once). That allows win_gui_logging_error to recover the same WinGuiSeat from its input LogPolicy pointer, which means it can get from there to the Seat facet of the same object, so that I don't need the extern variable 'win_seat' any more either.

Post-release destabilisation! Completely remove the struct type 'Config' in putty.h, which stores all PuTTY's settings and includes an arbitrary length limit on every single one of those settings which is stored in string form. In place of it is 'Conf', an opaque data type everywhere outside the new file conf.c, which stores a list of (key, value) pairs in which every key contains an integer identifying a configuration setting, and for some of those integers the key also contains extra parts (so that, for instance, CONF_environmt is a string-to-string mapping). Everywhere that a Config was previously used, a Conf is now; everywhere there was a Config structure copy, conf_copy() is called; every lookup, adjustment, load and save operation on a Config has been rewritten; and there's a mechanism for serialising a Conf into a binary blob and back for use with Duplicate Session. User-visible effects of this change _should_ be minimal, though I don't doubt I've introduced one or two bugs here and there which will eventually be found. The _intended_ visible effects of this change are that all arbitrary limits on configuration strings and lists (e.g. limit on number of port forwardings) should now disappear; that list boxes in the configuration will now be displayed in a sorted order rather than the arbitrary order in which they were added to the list (since the underlying data structure is now a sorted tree234 rather than an ad-hoc comma-separated string); and one more specific change, which is that local and dynamic port forwardings on the same port number are now mutually exclusive in the configuration (putting 'D' in the key rather than the value was a mistake in the first place). One other reorganisation as a result of this is that I've moved all the dialog.c standard handlers (dlg_stdeditbox_handler and friends) out into config.c, because I can't really justify calling them generic any more. When they took a pointer to an arbitrary structure type and the offset of a field within that structure, they were independent of whether that structure was a Config or something completely different, but now they really do expect to talk to a Conf, which can _only_ be used for PuTTY configuration, so I've renamed them all things like conf_editbox_handler and moved them out of the nominally independent dialog-box management module into the PuTTY-specific config.c.

Major destabilisation, phase 1. In this phase I've moved (I think) all the global and function-static variables out of terminal.c into a dynamically allocated data structure. Note that this does not yet confer the ability to run more than one of them in the same process, because other things (the line discipline, the back end) are still global, and also in particular the address of the dynamically allocated terminal-data structure is held in a global variable `term'. But what I've got here represents a reasonable stopping point at which to check things in. In _theory_ this should all still work happily, on both Unix and Windows. In practice, who knows?

Move the restricted_acl flag into winsecur.c. It's silly to set it at each call site of restrict_process_acl() if that function returns success!

lp_eventlog(&wgs.logpolicy, "Running with restricted process ACL");
Log when -restrict-acl is in use. Partly to reassure the user that they got what they asked for, and partly so that's a clue for us in the logs when we get bug reports. This involved repurposing platform_psftp_post_option_setup() (no longer used since e22120fe) as platform_psftp_pre_conn_setup(), and moving it to after logging is set up.

GUI PuTTY: stop using the global 'hwnd'. This was the difficult part of cleaning up that global variable. The main Windows PuTTY GUI is split between source files, so that _does_ actually need to refer to the main window from multiple places. But all the places where windlg.c needed to use 'hwnd' are seat methods, so they were already receiving a Seat pointer as a parameter. In other words, the methods of the Windows GUI Seat were already split between source files. So it seems only fair that they should be able to share knowledge of the seat's data as well. Hence, I've created a small 'WinGuiSeat' structure which both window.c and windlg.c can see the layout of, and put the main terminal window handle in there. Then the seat methods implemented in windlg.c, like win_seat_verify_ssh_host_key, can use container_of to turn the Seat pointer parameter back into the address of that structure, just as the methods in window.c can do (even though they currently don't need to). (Who knows: now that it _exists_, perhaps that structure can be gradually expanded in future to turn it into a proper encapsulation of all the Windows frontend's state, like we should have had all along...) I've also moved the Windows GUI LogPolicy implementation into the same object (i.e. WinGuiSeat implements both traits at once).

Telnet specials menu was not being reinstated after a session was restarted in the same window (Windows version only). Policy change: it's now the backend's responsibility to call update_specials_menu() at the start of a session (or whenever it feels ready), if it has any special commands. Otherwise the menu won't be displayed. [originally from svn r4649]

start_backend();
Turned the old `Telnet Command' System-submenu into a more general `Special Command' menu, in which any backend can place its own list of magical things the user might want to ask the backend to do. In particular I've implemented the recently proposed "break" extension in SSH2 using this mechanism. NB this checkin slightly breaks the Mac build, since it needs to provide at least a stub form of update_specials_menu(). [originally from svn r3054]

Retired the #ifdef DUMP_PACKETS stuff in ssh.c because I'm utterly sick of recompiling to enable packet dumps. SSH packet dumping is now provided as a logging option, and dumps to putty.log like all the other logging options. While I'm at it I cleaned up the format so that packet types are translated into strings for easy browsing. POSSIBLE SIDE EFFECT: in the course of this work I had to re-enable the SSH1 packet length checks which it turns out hadn't actually been active for some time, so it's possible things might break as a result.

Replace GetQueueStatus with PeekMessage(PM_NOREMOVE). A couple of users report that my recent reworking of the Windows top-level message loop has led to messages occasionally being lost, and MsgWaitForMultipleObjects blocking when it ought to have been called with a zero timeout. I haven't been able to reproduce this myself, but according to one reporter, PeekMessage(PM_NOREMOVE) is effective at checking for a non-empty message queue in a way that GetQueueStatus is not. Switch to using that instead. Thanks to Eric Flumerfelt for debugging and testing help. [originally from svn r10057]

Avoid leaving unread Windows messages in the queue. Jochen Erwied points out that once you've used PeekMessage to remove _one_ message from the message queue, MsgWaitForMultipleObjects will consider the whole queue to have been 'read', or at least looked at and deemed uninteresting, and so it will block until a further message comes in. Hence, my change in r10040 which stops us from looping on PeekMessage until the queue is empty has the effect of causing the rest of the message queue not to be acted on until a new message comes in to unblock it. Fix by checking if the queue is nonempty in advance of calling MsgWaitForMultipleObjects, and if so, giving it a zero timeout just as we do if there's a pending toplevel callback.

Stop Windows PuTTY becoming unresponsive if server floods us. This was an old bug, fixed around 0.59, which apparently regressed when I rewrote the main event loop using the toplevel_callback mechanism. Investigation just now suggests that it has to do with my faulty assumption that Windows PeekMessage would deliver messages in its message queue in FIFO order (i.e. that the thing calling itself a message queue is actually a _queue_). In fact my WM_NETEVENT seems to like to jump the queue, so that once a steady stream of them starts arriving, we never do anything else in the main event loop (except deal with handles). Worked around in a simple and slightly bodgy way, namely, we don't stop looping on PeekMessage and run our toplevel callbacks until we've either run out of messages completely or else seen at least one that _isn't_ a WM_NETEVENT. That way we should reliably interleave NETEVENT processing with processing of other stuff.

/*
* WM_NETEVENT messages seem to jump ahead of others in
* the message queue. I'm not sure why; the docs for
* PeekMessage mention that messages are prioritised in
* some way, but I'm unclear on which priorities go where.
*
* Anyway, in practice I observe that WM_NETEVENT seems to
* jump to the head of the queue, which means that if we
* were to only process one message every time round this
* loop, we'd get nothing but NETEVENTs if the server
* flooded us with data, and stop responding to any other
* kind of window message. So instead, we keep on round
* this loop until we've consumed at least one message
* that _isn't_ a NETEVENT, or run out of messages
* completely (whichever comes first). And we don't go to
* run_toplevel_callbacks (which is where the netevents
* are actually processed, causing fresh NETEVENT messages
* to appear) until we've done this.

Add GUI configuration for choice of clipboards. On all platforms, you can now configure which clipboard the mouse pastes from, which clipboard Ctrl-Ins and Shift-Ins access, and which Ctrl-Shift-C and Ctrl-Shift-V access. In each case, the options are: - nothing at all - a clipboard which is implicitly written by the act of mouse selection (the PRIMARY selection on X, CLIP_LOCAL everywhere else) - the standard clipboard written by explicit copy/paste UI actions (CLIPBOARD on X, the unique system clipboard elsewhere). Also, you can control whether selecting text with the mouse _also_ writes to the explicitly accessed clipboard. The wording of the various messages changes between platforms, but the basic UI shape is the same everywhere.

Switch some Conf settings over to being bool. I think this is the full set of things that ought logically to be boolean. One annoyance is that quite a few radio-button controls in config.c address Conf fields that are now bool rather than int, which means that the shared handler function can't just access them all with conf_{get,set}_int. Rather than back out the rigorous separation of int and bool in conf.c itself, I've just added a similar alternative handler function for the bool-typed ones.

Post-release destabilisation! Completely remove the struct type 'Config' in putty.h, which stores all PuTTY's settings and includes an arbitrary length limit on every single one of those settings which is stored in string form. In place of it is 'Conf', an opaque data type everywhere outside the new file conf.c, which stores a list of (key, value) pairs in which every key contains an integer identifying a configuration setting, and for some of those integers the key also contains extra parts (so that, for instance, CONF_environmt is a string-to-string mapping). Everywhere that a Config was previously used, a Conf is now; everywhere there was a Config structure copy, conf_copy() is called; every lookup, adjustment, load and save operation on a Config has been rewritten; and there's a mechanism for serialising a Conf into a binary blob and back for use with Duplicate Session. User-visible effects of this change _should_ be minimal, though I don't doubt I've introduced one or two bugs here and there which will eventually be found. The _intended_ visible effects of this change are that all arbitrary limits on configuration strings and lists (e.g. limit on number of port forwardings) should now disappear; that list boxes in the configuration will now be displayed in a sorted order rather than the arbitrary order in which they were added to the list (since the underlying data structure is now a sorted tree234 rather than an ad-hoc comma-separated string); and one more specific change, which is that local and dynamic port forwardings on the same port number are now mutually exclusive in the configuration (putting 'D' in the key rather than the value was a mistake in the first place). One other reorganisation as a result of this is that I've moved all the dialog.c standard handlers (dlg_stdeditbox_handler and friends) out into config.c, because I can't really justify calling them generic any more. When they took a pointer to an arbitrary structure type and the offset of a field within that structure, they were independent of whether that structure was a Config or something completely different, but now they really do expect to talk to a Conf, which can _only_ be used for PuTTY configuration, so I've renamed them all things like conf_editbox_handler and moved them out of the nominally independent dialog-box management module into the PuTTY-specific config.c.

Initial support for HTML Help. All the ad-hoc help-file finding code and various calls to WinHelp() have been centralised into a new file winhelp.c, which in turn has been modified to detect a .CHM file as well as .HLP and select between them as appropriate. It explicitly tries to load HHCTRL.OCX and use GetProcAddress, meaning that it _should_ still work correctly on pre-HTML-Help platforms, falling gracefully back to WinHelp, but although I tested this by temporarily renaming my own HHCTRL.OCX I haven't yet been able to test it on a real HTML-Help-free platform. Also in this checkin: a new .but file and docs makefile changes to make it convenient to build the sources for a .CHM. As yet, owing to limitations of Halibut's CHM support, I'm not able to write a .CHM directly, more's the pity. [originally from svn r7000]

New abstraction 'Seat', to pass to backends. This is a new vtable-based abstraction which is passed to a backend in place of Frontend, and it implements only the subset of the Frontend functions needed by a backend. (Many other Frontend functions still exist, notably the wide range of things called by terminal.c providing platform-independent operations on the GUI terminal window.) The purpose of making it a vtable is that this opens up the possibility of creating a backend as an internal implementation detail of some other activity, by providing just that one backend with a custom Seat that implements the methods differently. For example, this refactoring should make it feasible to directly implement an SSH proxy type, aka the 'jump host' feature supported by OpenSSH, aka 'open a secondary SSH session in MAINCHAN_DIRECT_TCP mode, and then expose the main channel of that as the Socket for the primary connection'. (Which of course you can already do by spawning 'plink -nc' as a separate proxy process, but this would permit it in the _same_ process without anything getting confused.) I've centralised a full set of stub methods in misc.c for the new abstraction, which allows me to get rid of several annoying stubs in the previous code. Also, while I'm here, I've moved a lot of duplicated modalfatalbox() type functions from application main program files into wincons.c / uxcons.c, which I think saves duplication overall. (A minor visible effect is that the prefixes on those console-based fatal error messages will now be more consistent between applications.)

Turn Backend into a sensible classoid. Nearly every part of the code that ever handles a full backend structure has historically done it using a pair of pointer variables, one pointing at a constant struct full of function pointers, and the other pointing to a 'void *' state object that's passed to each of those. While I'm modernising the rest of the code, this seems like a good time to turn that into the same more or less type-safe and less cumbersome system as I'm using for other parts of the code, such as Socket, Plug, BinaryPacketProtocol and so forth: the Backend structure contains a vtable pointer, and a system of macro wrappers handles dispatching through that vtable.

Convert a lot of 'int' variables to 'bool'. My normal habit these days, in new code, is to treat int and bool as _almost_ completely separate types. I'm still willing to use C's implicit test for zero on an integer (e.g. 'if (!blob.len)' is fine, no need to spell it out as blob.len != 0), but generally, if a variable is going to be conceptually a boolean, I like to declare it bool and assign to it using 'true' or 'false' rather than 0 or 1. PuTTY is an exception, because it predates the C99 bool, and I've stuck to its existing coding style even when adding new code to it. But it's been annoying me more and more, so now that I've decided C99 bool is an acceptable thing to require from our toolchain in the first place, here's a quite thorough trawl through the source doing 'boolification'. Many variables and function parameters are now typed as bool rather than int; many assignments of 0 or 1 to those variables are now spelled 'true' or 'false'. I managed this thorough conversion with the help of a custom clang plugin that I wrote to trawl the AST and apply heuristics to point out where things might want changing. So I've even managed to do a decent job on parts of the code I haven't looked at in years! To make the plugin's work easier, I pushed platform front ends generally in the direction of using standard 'bool' in preference to platform-specific boolean types like Windows BOOL or GTK's gboolean; I've left the platform booleans in places they _have_ to be for the platform APIs to work right, but variables only used by my own code have been converted wherever I found them. In a few places there are int values that look very like booleans in _most_ of the places they're used, but have a rarely-used third value, or a distinction between different nonzero values that most users don't care about. In these cases, I've _removed_ uses of 'true' and 'false' for the return values, to emphasise that there's something more subtle going on than a simple boolean answer: - the 'multisel' field in dialog.h's list box structure, for which the GTK front end in particular recognises a difference between 1 and 2 but nearly everything else treats as boolean - the 'urgent' parameter to plug_receive, where 1 vs 2 tells you something about the specific location of the urgent pointer, but most clients only care about 0 vs 'something nonzero' - the return value of wc_match, where -1 indicates a syntax error in the wildcard. - the return values from SSH-1 RSA-key loading functions, which use -1 for 'wrong passphrase' and 0 for all other failures (so any caller which already knows it's not loading an _encrypted private_ key can treat them as boolean) - term->esc_query, and the 'query' parameter in toggle_mode in terminal.c, which _usually_ hold 0 for ESC[123h or 1 for ESC[?123h, but can also hold -1 for some other intervening character that we don't support. In a few places there's an integer that I haven't turned into a bool even though it really _can_ only take values 0 or 1 (and, as above, tried to make the call sites consistent in not calling those values true and false), on the grounds that I thought it would make it more confusing to imply that the 0 value was in some sense 'negative' or bad and the 1 positive or good: - the return value of plug_accepting uses the POSIXish convention of 0=success and nonzero=error; I think if I made it bool then I'd also want to reverse its sense, and that's a job for a separate piece of work. - the 'screen' parameter to lineptr() in terminal.c, where 0 and 1 represent the default and alternate screens. There's no obvious reason why one of those should be considered 'true' or 'positive' or 'success' - they're just indices - so I've left it as int. ssh_scp_recv had particularly confusing semantics for its previous int return value: its call sites used '<= 0' to check for error, but it never actually returned a negative number, just 0 or 1. Now the function and its call sites agree that it's a bool. In a couple of places I've renamed variables called 'ret', because I don't like that name any more - it's unclear whether it means the return value (in preparation) for the _containing_ function or the return value received from a subroutine call, and occasionally I've accidentally used the same variable for both and introduced a bug. So where one of those got in my way, I've renamed it to 'toret' or 'retd' (the latter short for 'returned') in line with my usual modern practice, but I haven't done a thorough job of finding all of them. Finally, one amusing side effect of doing this is that I've had to separate quite a few chained assignments. It used to be perfectly fine to write 'a = b = c = TRUE' when a,b,c were int and TRUE was just a the 'true' defined by stdbool.h, that idiom provokes a warning from gcc: 'suggest parentheses around assignment used as truth value'!

GUI PuTTY: stop using the global 'hwnd'. This was the difficult part of cleaning up that global variable. The main Windows PuTTY GUI is split between source files, so that _does_ actually need to refer to the main window from multiple places. But all the places where windlg.c needed to use 'hwnd' are seat methods, so they were already receiving a Seat pointer as a parameter. In other words, the methods of the Windows GUI Seat were already split between source files. So it seems only fair that they should be able to share knowledge of the seat's data as well. Hence, I've created a small 'WinGuiSeat' structure which both window.c and windlg.c can see the layout of, and put the main terminal window handle in there. Then the seat methods implemented in windlg.c, like win_seat_verify_ssh_host_key, can use container_of to turn the Seat pointer parameter back into the address of that structure, just as the methods in window.c can do (even though they currently don't need to). (Who knows: now that it _exists_, perhaps that structure can be gradually expanded in future to turn it into a proper encapsulation of all the Windows frontend's state, like we should have had all along...) I've also moved the Windows GUI LogPolicy implementation into the same object (i.e. WinGuiSeat implements both traits at once). That allows win_gui_logging_error to recover the same WinGuiSeat from its input LogPolicy pointer, which means it can get from there to the Seat facet of the same object, so that I don't need the extern variable 'win_seat' any more either.

New abstraction 'Seat', to pass to backends. This is a new vtable-based abstraction which is passed to a backend in place of Frontend, and it implements only the subset of the Frontend functions needed by a backend. (Many other Frontend functions still exist, notably the wide range of things called by terminal.c providing platform-independent operations on the GUI terminal window.) The purpose of making it a vtable is that this opens up the possibility of creating a backend as an internal implementation detail of some other activity, by providing just that one backend with a custom Seat that implements the methods differently. For example, this refactoring should make it feasible to directly implement an SSH proxy type, aka the 'jump host' feature supported by OpenSSH, aka 'open a secondary SSH session in MAINCHAN_DIRECT_TCP mode, and then expose the main channel of that as the Socket for the primary connection'. (Which of course you can already do by spawning 'plink -nc' as a separate proxy process, but this would permit it in the _same_ process without anything getting confused.) I've centralised a full set of stub methods in misc.c for the new abstraction, which allows me to get rid of several annoying stubs in the previous code. Also, while I'm here, I've moved a lot of duplicated modalfatalbox() type functions from application main program files into wincons.c / uxcons.c, which I think saves duplication overall. (A minor visible effect is that the prefixes on those console-based fatal error messages will now be more consistent between applications.)

Remove a load of obsolete printf string limits. In the previous commit I happened to notice a %.150s in a ppl_logevent call, which was probably an important safety precaution a couple of decades ago when that format string was being used for an sprintf into a fixed-size buffer, but now it's just pointless cruft. This commit removes all printf string formatting directives with a compile-time fixed size, with the one exception of a %.3s used to cut out a 3-letter month name in scpserver.c. In cases where the format string in question was already going to an arbitrary-length function like dupprintf or ppl_logevent, that's all I've done; in cases where there was still a fixed-size buffer, I've replaced it with a dynamic buffer and dupprintf.

On Windows, show hidden mouse pointer on error. If a terminal window closed with a popup (due to a network error, for instance) while the mouse pointer was hidden by 'Hide mouse pointer when typing in window', the mouse pointer could remain hidden while over the terminal window, making it hard to navigate to the popup.

GUI PuTTY: stop using the global 'hwnd'. This was the difficult part of cleaning up that global variable. The main Windows PuTTY GUI is split between source files, so that _does_ actually need to refer to the main window from multiple places. But all the places where windlg.c needed to use 'hwnd' are seat methods, so they were already receiving a Seat pointer as a parameter. In other words, the methods of the Windows GUI Seat were already split between source files. So it seems only fair that they should be able to share knowledge of the seat's data as well. Hence, I've created a small 'WinGuiSeat' structure which both window.c and windlg.c can see the layout of, and put the main terminal window handle in there. Then the seat methods implemented in windlg.c, like win_seat_verify_ssh_host_key, can use container_of to turn the Seat pointer parameter back into the address of that structure, just as the methods in window.c can do (even though they currently don't need to). (Who knows: now that it _exists_, perhaps that structure can be gradually expanded in future to turn it into a proper encapsulation of all the Windows frontend's state, like we should have had all along...) I've also moved the Windows GUI LogPolicy implementation into the same object (i.e. WinGuiSeat implements both traits at once). That allows win_gui_logging_error to recover the same WinGuiSeat from its input LogPolicy pointer, which means it can get from there to the Seat facet of the same object, so that I don't need the extern variable 'win_seat' any more either.

Post-release destabilisation! Completely remove the struct type 'Config' in putty.h, which stores all PuTTY's settings and includes an arbitrary length limit on every single one of those settings which is stored in string form. In place of it is 'Conf', an opaque data type everywhere outside the new file conf.c, which stores a list of (key, value) pairs in which every key contains an integer identifying a configuration setting, and for some of those integers the key also contains extra parts (so that, for instance, CONF_environmt is a string-to-string mapping). Everywhere that a Config was previously used, a Conf is now; everywhere there was a Config structure copy, conf_copy() is called; every lookup, adjustment, load and save operation on a Config has been rewritten; and there's a mechanism for serialising a Conf into a binary blob and back for use with Duplicate Session. User-visible effects of this change _should_ be minimal, though I don't doubt I've introduced one or two bugs here and there which will eventually be found. The _intended_ visible effects of this change are that all arbitrary limits on configuration strings and lists (e.g. limit on number of port forwardings) should now disappear; that list boxes in the configuration will now be displayed in a sorted order rather than the arbitrary order in which they were added to the list (since the underlying data structure is now a sorted tree234 rather than an ad-hoc comma-separated string); and one more specific change, which is that local and dynamic port forwardings on the same port number are now mutually exclusive in the configuration (putting 'D' in the key rather than the value was a mistake in the first place). One other reorganisation as a result of this is that I've moved all the dialog.c standard handlers (dlg_stdeditbox_handler and friends) out into config.c, because I can't really justify calling them generic any more. When they took a pointer to an arbitrary structure type and the offset of a field within that structure, they were independent of whether that structure was a Config or something completely different, but now they really do expect to talk to a Conf, which can _only_ be used for PuTTY configuration, so I've renamed them all things like conf_editbox_handler and moved them out of the nominally independent dialog-box management module into the PuTTY-specific config.c.

Whitespace rationalisation of entire code base. The number of people has been steadily increasing who read our source code with an editor that thinks tab stops are 4 spaces apart, as opposed to the traditional tty-derived 8 that the PuTTY code expects. So I've been wondering for ages about just fixing it, and switching to a spaces-only policy throughout the code. And I recently found out about 'git blame -w', which should make this change not too disruptive for the purposes of source-control archaeology; so perhaps now is the time. While I'm at it, I've also taken the opportunity to remove all the trailing spaces from source lines (on the basis that git dislikes them, and is the only thing that seems to have a strong opinion one way or the other). Apologies to anyone downstream of this code who has complicated patch sets to rebase past this change. I don't intend it to be needed again.

Giant const-correctness patch of doom! Having found a lot of unfixed constness issues in recent development, I thought perhaps it was time to get proactive, so I compiled the whole codebase with -Wwrite-strings. That turned up a huge load of const problems, which I've fixed in this commit: the Unix build now goes cleanly through with -Wwrite-strings, and the Windows build is as close as I could get it (there are some lingering issues due to occasional Windows API functions like AcquireCredentialsHandle not having the right constness). Notable fallout beyond the purely mechanical changing of types: - the stuff saved by cmdline_save_param() is now explicitly dupstr()ed, and freed in cmdline_run_saved. - I couldn't make both string arguments to cmdline_process_param() const, because it intentionally writes to one of them in the case where it's the argument to -pw (in the vain hope of being at least slightly friendly to 'ps'), so elsewhere I had to temporarily dupstr() something for the sake of passing it to that function - I had to invent a silly parallel version of const_cmp() so I could pass const string literals in to lookup functions. - stripslashes() in pscp.c and psftp.c has the annoying strchr nature

Centralise palette setup into terminal.c. Now terminal.c makes nearly all the decisions about what the colour palette should actually contain: it does the job of reading the GUI-configurable colours out of Conf, and also the job of making up the rest of the xterm-256 palette. The only exception is that TermWin can provide a method to override some of the default colours, which on Windows is used to implement the 'Use system colours' config option. This saves code overall, partly because the front ends don't have to be able to send palette data back to the Terminal any more (the Terminal keeps the master copy and can answer palette-query escape sequences from its own knowledge), and also because now there's only one copy of the xterm-256 palette setup code (previously gtkwin.c and window.c each had their own version of it). In this rewrite, I've also introduced a multi-layered storage system for the palette data in Terminal. One layer contains the palette information derived from Conf; the next contains platform overrides (currently just Windows's 'Use system colours'); the last one contains overrides set by escape sequences in the middle of the session. The topmost two layers can each _conditionally_ override the ones below. As a result, if a server-side application manually resets (say) the default fg and bg colours in mid-session to something that works well in a particular application, those changes won't be wiped out by a change in the Windows system colours or the Conf, which they would have been before. Instead, changes in Conf or the system colours alter the lower layers of the structure, but then when palette_rebuild is called, the upper layer continues to override them, until a palette reset (ESC]R) or terminal reset (e.g. ESC c) removes those upper-layer changes. This seems like a more consistent strategy, in that the same set of configuration settings will produce the same end result regardless of what order they were applied in. The palette-related methods in TermWin have had a total rework. palette_get and palette_reset are both gone; palette_set can now set a contiguous range of colours in one go; and the new palette_get_overrides replaces window.c's old systopalette().

The palette-related methods in TermWin have had a total rework. palette_get and palette_reset are both gone; palette_set can now set a contiguous range of colours in one go; and the new palette_get_overrides replaces window.c's old systopalette().

Support OSC 4 terminal colour-palette queries. Markus Gans points out that some applications which (not at all unreasonably) don't trust $TERM to tell them the full capabilities of their terminal will use the sequence "OSC 4 ; nn ; ? BEL" to ask for the colour-palette value in position nn, and they may not particularly care _what_ the results are but they will use them to decide whether the right number of colour palette entries even exist.

Centralise palette setup into terminal.c. Now terminal.c makes nearly all the decisions about what the colour palette should actually contain: it does the job of reading the GUI-configurable colours out of Conf, and also the job of making up the rest of the xterm-256 palette. The only exception is that TermWin can provide a method to override some of the default colours, which on Windows is used to implement the 'Use system colours' config option. This saves code overall, partly because the front ends don't have to be able to send palette data back to the Terminal any more (the Terminal keeps the master copy and can answer palette-query escape sequences from its own knowledge), and also because now there's only one copy of the xterm-256 palette setup code (previously gtkwin.c and window.c each had their own version of it). In this rewrite, I've also introduced a multi-layered storage system for the palette data in Terminal. One layer contains the palette information derived from Conf; the next contains platform overrides (currently just Windows's 'Use system colours'); the last one contains overrides set by escape sequences in the middle of the session. The topmost two layers can each _conditionally_ override the ones below. As a result, if a server-side application manually resets (say) the default fg and bg colours in mid-session to something that works well in a particular application, those changes won't be wiped out by a change in the Windows system colours or the Conf, which they would have been before. Instead, changes in Conf or the system colours alter the lower layers of the structure, but then when palette_rebuild is called, the upper layer continues to override them, until a palette reset (ESC]R) or terminal reset (e.g. ESC c) removes those upper-layer changes. This seems like a more consistent strategy, in that the same set of configuration settings will produce the same end result regardless of what order they were applied in.

First-stage support for Unicode combining characters. The `chars' array of each `termline' structure now contains optional additional entries after the normal number of columns, which are used to chain a linked list of combining characters off any primary termchar that needs it. This means we support arbitrarily many combining characters per cell (unlike xterm's hard limit of 2). Cut and paste works correctly (selecting a character cell containing multiple code points causes all those code points to be cut and pasted). Display works by simply overlaying all the relevant characters on top of one another; this is good enough for Unix (xterm does the same thing), and mostly seems OK for Windows except that the Windows Unicode fonts have a nasty habit of not containing most of the combining characters and thus overlaying an unknown-code-point box on your perfectly good base glyph. I had no idea how to add support in the Mac do_text(), so I've simply stuck in an assertion that will trigger the first time a combining character is displayed, and hopefully this will bite someone with the clue to fix it.

Reinstate as much of the Windows font-linking behaviour as I can easily manage, by adopting a hybrid approach to Unicode text display. The old approach of simply calling ExtTextOutW provided font linking without us having to lift a finger, but didn't do the right thing when it came to bidirectional or Arabic-shaped text. Arabeyes' replacement exact_textout() supported the latter, but turned out to break the former (with no warning from the Windows API documentation, so it's not their fault). So now I've got a second wrapper layer called general_textout(), which splits the input string into substrings based on bidi character class. Any character liable to cause bidi or shaping behaviour if fed straight to ExtTextOutW is instead fed through Arabeyes' exact_textout(), but the rest is fed straight to ExtTextOutW as it used to be. The effect appears to be that font linking is restored for all characters _except_ Arabic and other bidi scripts, which means in particular that we are no longer in a state of regression over 0.57. (0.57 would have done font linking on Arabic as well, but would also have misbidied it, so we've merely exchanged one failure mode for another slightly less harmful one in that situation.)

Convert a lot of 'int' variables to 'bool'. My normal habit these days, in new code, is to treat int and bool as _almost_ completely separate types. I'm still willing to use C's implicit test for zero on an integer (e.g. 'if (!blob.len)' is fine, no need to spell it out as blob.len != 0), but generally, if a variable is going to be conceptually a boolean, I like to declare it bool and assign to it using 'true' or 'false' rather than 0 or 1. PuTTY is an exception, because it predates the C99 bool, and I've stuck to its existing coding style even when adding new code to it. But it's been annoying me more and more, so now that I've decided C99 bool is an acceptable thing to require from our toolchain in the first place, here's a quite thorough trawl through the source doing 'boolification'. Many variables and function parameters are now typed as bool rather than int; many assignments of 0 or 1 to those variables are now spelled 'true' or 'false'. I managed this thorough conversion with the help of a custom clang plugin that I wrote to trawl the AST and apply heuristics to point out where things might want changing. So I've even managed to do a decent job on parts of the code I haven't looked at in years! To make the plugin's work easier, I pushed platform front ends generally in the direction of using standard 'bool' in preference to platform-specific boolean types like Windows BOOL or GTK's gboolean; I've left the platform booleans in places they _have_ to be for the platform APIs to work right, but variables only used by my own code have been converted wherever I found them. In a few places there are int values that look very like booleans in _most_ of the places they're used, but have a rarely-used third value, or a distinction between different nonzero values that most users don't care about. In these cases, I've _removed_ uses of 'true' and 'false' for the return values, to emphasise that there's something more subtle going on than a simple boolean answer: - the 'multisel' field in dialog.h's list box structure, for which the GTK front end in particular recognises a difference between 1 and 2 but nearly everything else treats as boolean - the 'urgent' parameter to plug_receive, where 1 vs 2 tells you something about the specific location of the urgent pointer, but most clients only care about 0 vs 'something nonzero' - the return value of wc_match, where -1 indicates a syntax error in the wildcard. - the return values from SSH-1 RSA-key loading functions, which use -1 for 'wrong passphrase' and 0 for all other failures (so any caller which already knows it's not loading an _encrypted private_ key can treat them as boolean) - term->esc_query, and the 'query' parameter in toggle_mode in terminal.c, which _usually_ hold 0 for ESC[123h or 1 for ESC[?123h, but can also hold -1 for some other intervening character that we don't support. In a few places there's an integer that I haven't turned into a bool even though it really _can_ only take values 0 or 1 (and, as above, tried to make the call sites consistent in not calling those values true and false), on the grounds that I thought it would make it more confusing to imply that the 0 value was in some sense 'negative' or bad and the 1 positive or good: - the return value of plug_accepting uses the POSIXish convention of 0=success and nonzero=error; I think if I made it bool then I'd also want to reverse its sense, and that's a job for a separate piece of work. - the 'screen' parameter to lineptr() in terminal.c, where 0 and 1 represent the default and alternate screens. There's no obvious reason why one of those should be considered 'true' or 'positive' or 'success' - they're just indices - so I've left it as int. ssh_scp_recv had particularly confusing semantics for its previous int return value: its call sites used '<= 0' to check for error, but it never actually returned a negative number, just 0 or 1. Now the function and its call sites agree that it's a bool. In a couple of places I've renamed variables called 'ret', because I don't like that name any more - it's unclear whether it means the return value (in preparation) for the _containing_ function or the return value received from a subroutine call, and occasionally I've accidentally used the same variable for both and introduced a bug. So where one of those got in my way, I've renamed it to 'toret' or 'retd' (the latter short for 'returned') in line with my usual modern practice, but I haven't done a thorough job of finding all of them. Finally, one amusing side effect of doing this is that I've had to separate quite a few chained assignments. It used to be perfectly fine to write 'a = b = c = TRUE' when a,b,c were int and TRUE was just a the 'true' defined by stdbool.h, that idiom provokes a warning from gcc: 'suggest parentheses around assignment used as truth value'!

Stop general_textout() from trying to slice up the input clipping rectangle into smaller ones: it doesn't work any more, since the new variable-pitch code can now call general_textout() with a larger clipping rectangle than the text it's meant to be displaying. Instead, general_textout() now uses the same semantics as the next loop up in do_text_internal(): the first piece of text it displays uses the opacity setting passed in, which blanks the entire clipping rectangle if necessary, and then subsequent overlays are non-opaque.

Stop general_textout() from trying to slice up the input clipping rectangle into smaller ones: it doesn't work any more, since the new variable-pitch code can now call general_textout() with a larger clipping rectangle than the text it's meant to be displaying. Instead, general_textout() now uses the same semantics as the next loop up in do_text_internal(): the first piece of text it displays uses the opacity setting passed in, which blanks the entire clipping rectangle if necessary, and then subsequent overlays are non-opaque. And the same clipping rectangle is used throughout. [originally from svn r9067]

Reinstate as much of the Windows font-linking behaviour as I can easily manage, by adopting a hybrid approach to Unicode text display. The old approach of simply calling ExtTextOutW provided font linking without us having to lift a finger, but didn't do the right thing when it came to bidirectional or Arabic-shaped text. Arabeyes' replacement exact_textout() supported the latter, but turned out to break the former (with no warning from the Windows API documentation, so it's not their fault). So now I've got a second wrapper layer called general_textout(), which splits the input string into substrings based on bidi character class. Any character liable to cause bidi or shaping behaviour if fed straight to ExtTextOutW is instead fed through Arabeyes' exact_textout(), but the rest is fed straight to ExtTextOutW as it used to be. The effect appears to be that font linking is restored for all characters _except_ Arabic and other bidi scripts, which means in particular that we are no longer in a state of regression over 0.57. (0.57 would have done font linking on Arabic as well, but would also have misbidied it, so we've merely exchanged one failure mode for another slightly less harmful one in that situation.)

Support for using variable-pitch fonts for the terminal on Windows. Done in much the same way as it is in the GTK front end: the character cell width is determined using the font's digits (which seems to give generally not-too-offensive spacing in most cases, at the expense of Ms and Ws typically overhanging a bit into adjacent cells) and each character is centred in its cell. Overhangs never leave permanent droppings on the window, because the existing work done in r5003 handles them just fine even in this stressful scenario. There's a hacky new checkbox in the Appearance panel to make variable-pitch fonts appear in the font selector (they still don't by default, because I still think it's _usually_ not What You Want); the checkbox state is not actually stored as part of a saved session, but it should be automatically ticked when reloading a session that's got a variable pitch font selected.

Support SGR 9 for strikethrough effect on text. This is mostly easy: it's just like drawing an underline, except that you put it at a different height in the character cell. The only question is _where_ in the character cell. Pango, and Windows GetOutlineTextMetrics, will tell you exactly where the font wants to have it. Following xterm, I fall back to 3/8 of the font's ascent (above the baseline) if either of those is unavailable.

Post-release destabilisation! Completely remove the struct type 'Config' in putty.h, which stores all PuTTY's settings and includes an arbitrary length limit on every single one of those settings which is stored in string form. In place of it is 'Conf', an opaque data type everywhere outside the new file conf.c, which stores a list of (key, value) pairs in which every key contains an integer identifying a configuration setting, and for some of those integers the key also contains extra parts (so that, for instance, CONF_environmt is a string-to-string mapping). Everywhere that a Config was previously used, a Conf is now; everywhere there was a Config structure copy, conf_copy() is called; every lookup, adjustment, load and save operation on a Config has been rewritten; and there's a mechanism for serialising a Conf into a binary blob and back for use with Duplicate Session. User-visible effects of this change _should_ be minimal, though I don't doubt I've introduced one or two bugs here and there which will eventually be found. The _intended_ visible effects of this change are that all arbitrary limits on configuration strings and lists (e.g. limit on number of port forwardings) should now disappear; that list boxes in the configuration will now be displayed in a sorted order rather than the arbitrary order in which they were added to the list (since the underlying data structure is now a sorted tree234 rather than an ad-hoc comma-separated string); and one more specific change, which is that local and dynamic port forwardings on the same port number are now mutually exclusive in the configuration (putting 'D' in the key rather than the value was a mistake in the first place). One other reorganisation as a result of this is that I've moved all the dialog.c standard handlers (dlg_stdeditbox_handler and friends) out into config.c, because I can't really justify calling them generic any more. When they took a pointer to an arbitrary structure type and the offset of a field within that structure, they were independent of whether that structure was a Config or something completely different, but now they really do expect to talk to a Conf, which can _only_ be used for PuTTY configuration, so I've renamed them all things like conf_editbox_handler and moved them out of the nominally independent dialog-box management module into the PuTTY-specific config.c.

GUI PuTTY: stop using the global 'hwnd'. This was the difficult part of cleaning up that global variable. The main Windows PuTTY GUI is split between source files, so that _does_ actually need to refer to the main window from multiple places. But all the places where windlg.c needed to use 'hwnd' are seat methods, so they were already receiving a Seat pointer as a parameter. In other words, the methods of the Windows GUI Seat were already split between source files. So it seems only fair that they should be able to share knowledge of the seat's data as well. Hence, I've created a small 'WinGuiSeat' structure which both window.c and windlg.c can see the layout of, and put the main terminal window handle in there. Then the seat methods implemented in windlg.c, like win_seat_verify_ssh_host_key, can use container_of to turn the Seat pointer parameter back into the address of that structure, just as the methods in window.c can do (even though they currently don't need to). (Who knows: now that it _exists_, perhaps that structure can be gradually expanded in future to turn it into a proper encapsulation of all the Windows frontend's state, like we should have had all along...) I've also moved the Windows GUI LogPolicy implementation into the same object (i.e. WinGuiSeat implements both traits at once). That allows win_gui_logging_error to recover the same WinGuiSeat from its input LogPolicy pointer, which means it can get from there to the Seat facet of the same object, so that I don't need the extern variable 'win_seat' any more either.

The number of people has been steadily increasing who read our source code with an editor that thinks tab stops are 4 spaces apart, as opposed to the traditional tty-derived 8 that the PuTTY code expects. So I've been wondering for ages about just fixing it, and switching to a spaces-only policy throughout the code. And I recently found out about 'git blame -w', which should make this change not too disruptive for the purposes of source-control archaeology; so perhaps now is the time. While I'm at it, I've also taken the opportunity to remove all the trailing spaces from source lines (on the basis that git dislikes them, and is the only thing that seems to have a strong opinion one way or the other). Apologies to anyone downstream of this code who has complicated patch sets to rebase past this change. I don't intend it to be needed again.

All font sizes should now be measured in points, and everything should be consistent, and (with any luck) old Registry settings should adapt gracefully too. [originally from svn r992]

RDB's patch: - use WM_TIMER for various things (blinking cursor; updates while moving/sizing; coping with overloading influx of netevents) - clip text output to avoid underlines outside character cell - even more careful font selection (we can now do OEMANSI by default) - a few extra keyboard mappings from the VTxxx terminals [originally from svn r418]

Post-release destabilisation! Completely remove the struct type 'Config' in putty.h, which stores all PuTTY's settings and includes an arbitrary length limit on every single one of those settings which is stored in string form. In place of it is 'Conf', an opaque data type everywhere outside the new file conf.c, which stores a list of (key, value) pairs in which every key contains an integer identifying a configuration setting, and for some of those integers the key also contains extra parts (so that, for instance, CONF_environmt is a string-to-string mapping). Everywhere that a Config was previously used, a Conf is now; everywhere there was a Config structure copy, conf_copy() is called; every lookup, adjustment, load and save operation on a Config has been rewritten; and there's a mechanism for serialising a Conf into a binary blob and back for use with Duplicate Session. User-visible effects of this change _should_ be minimal, though I don't doubt I've introduced one or two bugs here and there which will eventually be found. The _intended_ visible effects of this change are that all arbitrary limits on configuration strings and lists (e.g. limit on number of port forwardings) should now disappear; that list boxes in the configuration will now be displayed in a sorted order rather than the arbitrary order in which they were added to the list (since the underlying data structure is now a sorted tree234 rather than an ad-hoc comma-separated string); and one more specific change, which is that local and dynamic port forwardings on the same port number are now mutually exclusive in the configuration (putting 'D' in the key rather than the value was a mistake in the first place). One other reorganisation as a result of this is that I've moved all the dialog.c standard handlers (dlg_stdeditbox_handler and friends) out into config.c, because I can't really justify calling them generic any more. When they took a pointer to an arbitrary structure type and the offset of a field within that structure, they were independent of whether that structure was a Config or something completely different, but now they really do expect to talk to a Conf, which can _only_ be used for PuTTY configuration, so I've renamed them all things like conf_editbox_handler and moved them out of the nominally independent dialog-box management module into the PuTTY-specific config.c.

Support SGR 9 for strikethrough effect on text. This is mostly easy: it's just like drawing an underline, except that you put it at a different height in the character cell. The only question is _where_ in the character cell. Pango, and Windows GetOutlineTextMetrics, will tell you exactly where the font wants to have it. Following xterm, I fall back to 3/8 of the font's ascent (above the baseline) if either of those is unavailable.

Support for using variable-pitch fonts for the terminal on Windows. Done in much the same way as it is in the GTK front end: the character cell width is determined using the font's digits (which seems to give generally not-too-offensive spacing in most cases, at the expense of Ms and Ws typically overhanging a bit into adjacent cells) and each character is centred in its cell. Overhangs never leave permanent droppings on the window, because the existing work done in r5003 handles them just fine even in this stressful scenario. There's a hacky new checkbox in the Appearance panel to make variable-pitch fonts appear in the font selector (they still don't by default, because I still think it's _usually_ not What You Want); the checkbox state is not actually stored as part of a saved session, but it should be automatically ticked when reloading a session that's got a variable pitch font selected.

#ifdef RDB_DEBUG_PATCH
Start using C99 variadic macros. In the past, I've had a lot of macros which you call with double parentheses, along the lines of debug(("format string", params)), so that the inner parens protect the commas and permit the macro to treat the whole printf-style argument list as one macro argument. That's all very well, but it's a bit inconvenient (it doesn't leave you any way to implement such a macro by prepending another argument to the list), and now this code base's rules allow C99isms, I can switch all those macros to using a single pair of parens, using the C99 ability to say '...' in the parameter list of the #define and get at the corresponding suffix of the arguments as __VA_ARGS__. So I'm doing it. I've made the following printf-style macros variadic: bpp_logevent, ppl_logevent, ppl_printf and debug. While I'm here, I've also fixed up a collection of conditioned-out calls to debug() in the Windows front end which were clearly expecting a macro with a different calling syntax, because they had an integer parameter first. If I ever have a need to condition those back in, they should actually work now.

Convert a lot of 'int' variables to 'bool'. My normal habit these days, in new code, is to treat int and bool as _almost_ completely separate types. I'm still willing to use C's implicit test for zero on an integer (e.g. 'if (!blob.len)' is fine, no need to spell it out as blob.len != 0), but generally, if a variable is going to be conceptually a boolean, I like to declare it bool and assign to it using 'true' or 'false' rather than 0 or 1. PuTTY is an exception, because it predates the C99 bool, and I've stuck to its existing coding style even when adding new code to it. But it's been annoying me more and more, so now that I've decided C99 bool is an acceptable thing to require from our toolchain in the first place, here's a quite thorough trawl through the source doing 'boolification'. Many variables and function parameters are now typed as bool rather than int; many assignments of 0 or 1 to those variables are now spelled 'true' or 'false'. I managed this thorough conversion with the help of a custom clang plugin that I wrote to trawl the AST and apply heuristics to point out where things might want changing. So I've even managed to do a decent job on parts of the code I haven't looked at in years! To make the plugin's work easier, I pushed platform front ends generally in the direction of using standard 'bool' in preference to platform-specific boolean types like Windows BOOL or GTK's gboolean; I've left the platform booleans in places they _have_ to be for the platform APIs to work right, but variables only used by my own code have been converted wherever I found them. In a few places there are int values that look very like booleans in _most_ of the places they're used, but have a rarely-used third value, or a distinction between different nonzero values that most users don't care about. In these cases, I've _removed_ uses of 'true' and 'false' for the return values, to emphasise that there's something more subtle going on than a simple boolean answer: - the 'multisel' field in dialog.h's list box structure, for which the GTK front end in particular recognises a difference between 1 and 2 but nearly everything else treats as boolean - the 'urgent' parameter to plug_receive, where 1 vs 2 tells you something about the specific location of the urgent pointer, but most clients only care about 0 vs 'something nonzero' - the return value of wc_match, where -1 indicates a syntax error in the wildcard. - the return values from SSH-1 RSA-key loading functions, which use -1 for 'wrong passphrase' and 0 for all other failures (so any caller which already knows it's not loading an _encrypted private_ key can treat them as boolean) - term->esc_query, and the 'query' parameter in toggle_mode in terminal.c, which _usually_ hold 0 for ESC[123h or 1 for ESC[?123h, but can also hold -1 for some other intervening character that we don't support. In a few places there's an integer that I haven't turned into a bool even though it really _can_ only take values 0 or 1 (and, as above, tried to make the call sites consistent in not calling those values true and false), on the grounds that I thought it would make it more confusing to imply that the 0 value was in some sense 'negative' or bad and the 1 positive or good: - the return value of plug_accepting uses the POSIXish convention of 0=success and nonzero=error; I think if I made it bool then I'd also want to reverse its sense, and that's a job for a separate piece of work. - the 'screen' parameter to lineptr() in terminal.c, where 0 and 1 represent the default and alternate screens. There's no obvious reason why one of those should be considered 'true' or 'positive' or 'success' - they're just indices - so I've left it as int. ssh_scp_recv had particularly confusing semantics for its previous int return value: its call sites used '<= 0' to check for error, but it never actually returned a negative number, just 0 or 1. Now the function and its call sites agree that it's a bool. In a couple of places I've renamed variables called 'ret', because I don't like that name any more - it's unclear whether it means the return value (in preparation) for the _containing_ function or the return value received from a subroutine call, and occasionally I've accidentally used the same variable for both and introduced a bug. So where one of those got in my way, I've renamed it to 'toret' or 'retd' (the latter short for 'returned') in line with my usual modern practice, but I haven't done a thorough job of finding all of them. Finally, one amusing side effect of doing this is that I've had to separate quite a few chained assignments. It used to be perfectly fine to write 'a = b = c = TRUE' when a,b,c were int and TRUE was just a the 'true' defined by stdbool.h, that idiom provokes a warning from gcc: 'suggest parentheses around assignment used as truth value'!

GUI PuTTY: stop using the global 'hwnd'. This was the difficult part of cleaning up that global variable. The main Windows PuTTY GUI is split between source files, so that _does_ actually need to refer to the main window from multiple places. But all the places where windlg.c needed to use 'hwnd' are seat methods, so they were already receiving a Seat pointer as a parameter. In other words, the methods of the Windows GUI Seat were already split between source files. So it seems only fair that they should be able to share knowledge of the seat's data as well. Hence, I've created a small 'WinGuiSeat' structure which both window.c and windlg.c can see the layout of, and put the main terminal window handle in there. Then the seat methods implemented in windlg.c, like win_seat_verify_ssh_host_key, can use container_of to turn the Seat pointer parameter back into the address of that structure, just as the methods in window.c can do (even though they currently don't need to). (Who knows: now that it _exists_, perhaps that structure can be gradually expanded in future to turn it into a proper encapsulation of all the Windows frontend's state, like we should have had all along...) I've also moved the Windows GUI LogPolicy implementation into the same object (i.e. WinGuiSeat implements both traits at once). That allows win_gui_logging_error to recover the same WinGuiSeat from its input LogPolicy pointer, which means it can get from there to the Seat facet of the same object, so that I don't need the extern variable 'win_seat' any more either.

Convert a lot of 'int' variables to 'bool'. My normal habit these days, in new code, is to treat int and bool as _almost_ completely separate types. I'm still willing to use C's implicit test for zero on an integer (e.g. 'if (!blob.len)' is fine, no need to spell it out as blob.len != 0), but generally, if a variable is going to be conceptually a boolean, I like to declare it bool and assign to it using 'true' or 'false' rather than 0 or 1. PuTTY is an exception, because it predates the C99 bool, and I've stuck to its existing coding style even when adding new code to it.

Post-release destabilisation! Completely remove the struct type 'Config' in putty.h, which stores all PuTTY's settings and includes an arbitrary length limit on every single one of those settings which is stored in string form. In place of it is 'Conf', an opaque data type everywhere outside the new file conf.c, which stores a list of (key, value) pairs in which every key contains an integer identifying a configuration setting, and for some of those integers the key also contains extra parts (so that, for instance, CONF_environmt is a string-to-string mapping). Everywhere that a Config was previously used, a Conf is now; everywhere there was a Config structure copy, conf_copy() is called; every lookup, adjustment, load and save operation on a Config has been rewritten; and there's a mechanism for serialising a Conf into a binary blob and back for use with Duplicate Session. User-visible effects of this change _should_ be minimal, though I don't doubt I've introduced one or two bugs here and there which will eventually be found. The _intended_ visible effects of this change are that all arbitrary limits on configuration strings and lists (e.g. limit on number of port forwardings) should now disappear; that list boxes in the configuration will now be displayed in a sorted order rather than the arbitrary order in which they were added to the list (since the underlying data structure is now a sorted tree234 rather than an ad-hoc comma-separated string); and one more specific change, which is that local and dynamic port forwardings on the same port number are now mutually exclusive in the configuration (putting 'D' in the key rather than the value was a mistake in the first place). One other reorganisation as a result of this is that I've moved all the dialog.c standard handlers (dlg_stdeditbox_handler and friends) out into config.c, because I can't really justify calling them generic any more. When they took a pointer to an arbitrary structure type and the offset of a field within that structure, they were independent of whether that structure was a Config or something completely different, but now they really do expect to talk to a Conf, which can _only_ be used for PuTTY configuration, so I've renamed them all things like conf_editbox_handler and moved them out of the nominally independent dialog-box management module into the PuTTY-specific config.c.

I'm still willing to use C's implicit test for zero on an integer (e.g. 'if (!blob.len)' is fine, no need to spell it out as blob.len != 0), but generally, if a variable is going to be conceptually a boolean, I like to declare it bool and assign to it using 'true' or 'false' rather than 0 or 1. PuTTY is an exception, because it predates the C99 bool, and I've stuck to its existing coding style even when adding new code to it. But it's been annoying me more and more, so now that I've decided C99 bool is an acceptable thing to require from our toolchain in the first place, here's a quite thorough trawl through the source doing 'boolification'. Many variables and function parameters are now typed as bool rather than int; many assignments of 0 or 1 to those variables are now spelled 'true' or 'false'. I managed this thorough conversion with the help of a custom clang plugin that I wrote to trawl the AST and apply heuristics to point out where things might want changing. So I've even managed to do a decent job on parts of the code I haven't looked at in years! To make the plugin's work easier, I pushed platform front ends generally in the direction of using standard 'bool' in preference to platform-specific boolean types like Windows BOOL or GTK's gboolean; I've left the platform booleans in places they _have_ to be for the platform APIs to work right, but variables only used by my own code have been converted wherever I found them. In a few places there are int values that look very like booleans in _most_ of the places they're used, but have a rarely-used third value, or a distinction between different nonzero values that most users don't care about. In these cases, I've _removed_ uses of 'true' and 'false' for the return values, to emphasise that there's something more subtle going on than a simple boolean answer: - the 'multisel' field in dialog.h's list box structure, for which the GTK front end in particular recognises a difference between 1 and 2 but nearly everything else treats as boolean - the 'urgent' parameter to plug_receive, where 1 vs 2 tells you something about the specific location of the urgent pointer, but most clients only care about 0 vs 'something nonzero' - the return value of wc_match, where -1 indicates a syntax error in the wildcard. - the return values from SSH-1 RSA-key loading functions, which use -1 for 'wrong passphrase' and 0 for all other failures (so any caller which already knows it's not loading an _encrypted private_ key can treat them as boolean) - term->esc_query, and the 'query' parameter in toggle_mode in terminal.c, which _usually_ hold 0 for ESC[123h or 1 for ESC[?123h, but can also hold -1 for some other intervening character that we don't support. In a few places there's an integer that I haven't turned into a bool even though it really _can_ only take values 0 or 1 (and, as above, tried to make the call sites consistent in not calling those values true and false), on the grounds that I thought it would make it more confusing to imply that the 0 value was in some sense 'negative' or bad and the 1 positive or good: - the return value of plug_accepting uses the POSIXish convention of 0=success and nonzero=error; I think if I made it bool then I'd also want to reverse its sense, and that's a job for a separate piece of work. - the 'screen' parameter to lineptr() in terminal.c, where 0 and 1 represent the default and alternate screens. There's no obvious reason why one of those should be considered 'true' or 'positive' or 'success' - they're just indices - so I've left it as int. ssh_scp_recv had particularly confusing semantics for its previous int return value: its call sites used '<= 0' to check for error, but it never actually returned a negative number, just 0 or 1. Now the function and its call sites agree that it's a bool. In a couple of places I've renamed variables called 'ret', because I don't like that name any more - it's unclear whether it means the return value (in preparation) for the _containing_ function or the return value received from a subroutine call, and occasionally I've accidentally used the same variable for both and introduced a bug. So where one of those got in my way, I've renamed it to 'toret' or 'retd' (the latter short for 'returned') in line with my usual modern practice, but I haven't done a thorough job of finding all of them. Finally, one amusing side effect of doing this is that I've had to separate quite a few chained assignments. It used to be perfectly fine to write 'a = b = c = TRUE' when a,b,c were int and TRUE was just a the 'true' defined by stdbool.h, that idiom provokes a warning from gcc: 'suggest parentheses around assignment used as truth value'!

RDB's Unicode patch. Fonts are now used in Unicode mode where possible and we have a single unified means of trying to display any Unicode code point.

Post-release destabilisation! Completely remove the struct type 'Config' in putty.h, which stores all PuTTY's settings and includes an arbitrary length limit on every single one of those settings which is stored in string form. In place of it is 'Conf', an opaque data type everywhere outside the new file conf.c, which stores a list of (key, value) pairs in which every key contains an integer identifying a configuration setting, and for some of those integers the key also contains extra parts (so that, for instance, CONF_environmt is a string-to-string mapping). Everywhere that a Config was previously used, a Conf is now; everywhere there was a Config structure copy, conf_copy() is called; every lookup, adjustment, load and save operation on a Config has been rewritten; and there's a mechanism for serialising a Conf into a binary blob and back for use with Duplicate Session. User-visible effects of this change _should_ be minimal, though I don't doubt I've introduced one or two bugs here and there which will eventually be found. The _intended_ visible effects of this change are that all arbitrary limits on configuration strings and lists (e.g. limit on number of port forwardings) should now disappear; that list boxes in the configuration will now be displayed in a sorted order rather than the arbitrary order in which they were added to the list (since the underlying data structure is now a sorted tree234 rather than an ad-hoc comma-separated string); and one more specific change, which is that local and dynamic port forwardings on the same port number are now mutually exclusive in the configuration (putting 'D' in the key rather than the value was a mistake in the first place). One other reorganisation as a result of this is that I've moved all the dialog.c standard handlers (dlg_stdeditbox_handler and friends) out into config.c, because I can't really justify calling them generic any more. When they took a pointer to an arbitrary structure type and the offset of a field within that structure, they were independent of whether that structure was a Config or something completely different, but now they really do expect to talk to a Conf, which can _only_ be used for PuTTY configuration, so I've renamed them all things like conf_editbox_handler and moved them out of the nominally independent dialog-box management module into the PuTTY-specific config.c.

Whitespace rationalisation of entire code base. The number of people has been steadily increasing who read our source code with an editor that thinks tab stops are 4 spaces apart, as opposed to the traditional tty-derived 8 that the PuTTY code expects. So I've been wondering for ages about just fixing it, and switching to a spaces-only policy throughout the code. And I recently found out about 'git blame -w', which should make this change not too disruptive for the purposes of source-control archaeology; so perhaps now is the time. While I'm at it, I've also taken the opportunity to remove all the trailing spaces from source lines (on the basis that git dislikes them, and is the only thing that seems to have a strong opinion one way or the other). Apologies to anyone downstream of this code who has complicated patch sets to rebase past this change. I don't intend it to be needed again.

When they took a pointer to an arbitrary structure type and the offset of a field within that structure, they were independent of whether that structure was a Config or something completely different, but now they really do expect to talk to a Conf, which can _only_ be used for PuTTY configuration, so I've renamed them all things like conf_editbox_handler and moved them out of the nominally independent dialog-box management module into the PuTTY-specific config.c.

Convert a lot of 'int' variables to 'bool'. My normal habit these days, in new code, is to treat int and bool as _almost_ completely separate types. I'm still willing to use C's implicit test for zero on an integer (e.g. 'if (!blob.len)' is fine, no need to spell it out as blob.len != 0), but generally, if a variable is going to be conceptually a boolean, I like to declare it bool and assign to it using 'true' or 'false' rather than 0 or 1. PuTTY is an exception, because it predates the C99 bool, and I've stuck to its existing coding style even when adding new code to it. But it's been annoying me more and more, so now that I've decided C99 bool is an acceptable thing to require from our toolchain in the first place, here's a quite thorough trawl through the source doing 'boolification'. Many variables and function parameters are now typed as bool rather than int; many assignments of 0 or 1 to those variables are now spelled 'true' or 'false'. I managed this thorough conversion with the help of a custom clang plugin that I wrote to trawl the AST and apply heuristics to point out where things might want changing. So I've even managed to do a decent job on parts of the code I haven't looked at in years! To make the plugin's work easier, I pushed platform front ends generally in the direction of using standard 'bool' in preference to platform-specific boolean types like Windows BOOL or GTK's gboolean; I've left the platform booleans in places they _have_ to be for the platform APIs to work right, but variables only used by my own code have been converted wherever I found them. In a few places there are int values that look very like booleans in _most_ of the places they're used, but have a rarely-used third value, or a distinction between different nonzero values that most users don't care about. In these cases, I've _removed_ uses of 'true' and 'false' for the return values, to emphasise that there's something more subtle going on than a simple boolean answer: - the 'multisel' field in dialog.h's list box structure, for which the GTK front end in particular recognises a difference between 1 and 2 but nearly everything else treats as boolean - the 'urgent' parameter to plug_receive, where 1 vs 2 tells you something about the specific location of the urgent pointer, but most clients only care about 0 vs 'something nonzero' - the return value of wc_match, where -1 indicates a syntax error in the wildcard. - the return values from SSH-1 RSA-key loading functions, which use -1 for 'wrong passphrase' and 0 for all other failures (so any caller which already knows it's not loading an _encrypted private_ key can treat them as boolean) - term->esc_query, and the 'query' parameter in toggle_mode in terminal.c, which _usually_ hold 0 for ESC[123h or 1 for ESC[?123h, but can also hold -1 for some other intervening character that we don't support. In a few places there's an integer that I haven't turned into a bool even though it really _can_ only take values 0 or 1 (and, as above, tried to make the call sites consistent in not calling those values true and false), on the grounds that I thought it would make it more confusing to imply that the 0 value was in some sense 'negative' or bad and the 1 positive or good: - the return value of plug_accepting uses the POSIXish convention of 0=success and nonzero=error; I think if I made it bool then I'd also want to reverse its sense, and that's a job for a separate piece of work. - the 'screen' parameter to lineptr() in terminal.c, where 0 and 1 represent the default and alternate screens. There's no obvious reason why one of those should be considered 'true' or 'positive' or 'success' - they're just indices - so I've left it as int. ssh_scp_recv had particularly confusing semantics for its previous int return value: its call sites used '<= 0' to check for error, but it never actually returned a negative number, just 0 or 1. Now the function and its call sites agree that it's a bool. In a couple of places I've renamed variables called 'ret', because I don't like that name any more - it's unclear whether it means the return value (in preparation) for the _containing_ function or the return value received from a subroutine call, and occasionally I've accidentally used the same variable for both and introduced a bug. So where one of those got in my way, I've renamed it to 'toret' or 'retd' (the latter short for 'returned') in line with my usual modern practice, but I haven't done a thorough job of finding all of them. Finally, one amusing side effect of doing this is that I've had to separate quite a few chained assignments. It used to be perfectly fine to write 'a = b = c = TRUE' when a,b,c were int and TRUE was just a the 'true' defined by stdbool.h, that idiom provokes a warning from gcc: 'suggest parentheses around assignment used as truth value'!

Remove the 'Frontend' type and replace it with a vtable. After the recent Seat and LogContext revamps, _nearly_ all the remaining uses of the type 'Frontend' were in terminal.c, which needs all sorts of interactions with the GUI window the terminal lives in, from the obvious (actually drawing text on the window, reading and writing the clipboard) to the obscure (minimising, maximising and moving the window in response to particular escape sequences). All of those functions are now provided by an abstraction called TermWin. The few remaining uses of Frontend after _that_ are internal to a particular platform directory, so as to spread the implementation of that particular kind of Frontend between multiple source files; so I've renamed all of those so that they take a more specifically named type that refers to the particular implementation rather than the general abstraction. So now the name 'Frontend' no longer exists in the code base at all, and everywhere one used to be used, it's completely clear whether it was operating in one of Frontend's three abstract roles (and if so, which), or whether it was specific to a particular implementation. Another type that's disappeared is 'Context', which used to be a typedef defined to something different on each platform, describing whatever short-lived resources were necessary to draw on the terminal window: the front end would provide a ready-made one when calling term_paint, and the terminal could request one with get_ctx/free_ctx if it wanted to do proactive window updates. Now that drawing context lives inside the TermWin itself, because there was never any need to have two of those contexts live at the same time. (Another minor API change is that the window-title functions - both reading and writing - have had a missing 'const' added to their char * parameters / return values.) I don't expect this change to enable any particularly interesting new functionality (in particular, I have no plans that need more than one implementation of TermWin in the same application). But it completes the tidying-up that began with the Seat and LogContext rework.

GUI PuTTY: stop using the global 'hwnd'. This was the difficult part of cleaning up that global variable. The main Windows PuTTY GUI is split between source files, so that _does_ actually need to refer to the main window from multiple places. But all the places where windlg.c needed to use 'hwnd' are seat methods, so they were already receiving a Seat pointer as a parameter. In other words, the methods of the Windows GUI Seat were already split between source files. So it seems only fair that they should be able to share knowledge of the seat's data as well. Hence, I've created a small 'WinGuiSeat' structure which both window.c and windlg.c can see the layout of, and put the main terminal window handle in there. Then the seat methods implemented in windlg.c, like win_seat_verify_ssh_host_key, can use container_of to turn the Seat pointer parameter back into the address of that structure, just as the methods in window.c can do (even though they currently don't need to). (Who knows: now that it _exists_, perhaps that structure can be gradually expanded in future to turn it into a proper encapsulation of all the Windows frontend's state, like we should have had all along...) I've also moved the Windows GUI LogPolicy implementation into the same object (i.e. WinGuiSeat implements both traits at once). That allows win_gui_logging_error to recover the same WinGuiSeat from its input LogPolicy pointer, which means it can get from there to the Seat facet of the same object, so that I don't need the extern variable 'win_seat' any more either.

Post-release destabilisation! Completely remove the struct type 'Config' in putty.h, which stores all PuTTY's settings and includes an arbitrary length limit on every single one of those settings which is stored in string form. In place of it is 'Conf', an opaque data type everywhere outside the new file conf.c, which stores a list of (key, value) pairs in which every key contains an integer identifying a configuration setting, and for some of those integers the key also contains extra parts (so that, for instance, CONF_environmt is a string-to-string mapping). Everywhere that a Config was previously used, a Conf is now; everywhere there was a Config structure copy, conf_copy() is called; every lookup, adjustment, load and save operation on a Config has been rewritten; and there's a mechanism for serialising a Conf into a binary blob and back for use with Duplicate Session. User-visible effects of this change _should_ be minimal, though I don't doubt I've introduced one or two bugs here and there which will eventually be found. The _intended_ visible effects of this change are that all arbitrary limits on configuration strings and lists (e.g. limit on number of port forwardings) should now disappear; that list boxes in the configuration will now be displayed in a sorted order rather than the arbitrary order in which they were added to the list (since the underlying data structure is now a sorted tree234 rather than an ad-hoc comma-separated string); and one more specific change, which is that local and dynamic port forwardings on the same port number are now mutually exclusive in the configuration (putting 'D' in the key rather than the value was a mistake in the first place).

Major destabilisation, phase 1. In this phase I've moved (I think) all the global and function-static variables out of terminal.c into a dynamically allocated data structure.

But what I've got here represents a reasonable stopping point at which to check things in. In _theory_ this should all still work happily, on both Unix and Windows. In practice, who knows?

(Who knows: now that it _exists_, perhaps that structure can be gradually expanded in future to turn it into a proper encapsulation of all the Windows frontend's state, like we should have had all along...) I've also moved the Windows GUI LogPolicy implementation into the same object (i.e. WinGuiSeat implements both traits at once). That allows win_gui_logging_error to recover the same WinGuiSeat from its input LogPolicy pointer, which means it can get from there to the Seat facet of the same object, so that I don't need the extern variable 'win_seat' any more either.

Fix missing recalculation of window border. If you open a Windows PuTTY session and press Win+Right, Windows auto-sizes the terminal window to cover the right-hand half of the screen. Then if you press Win+Up it will be auto-sized again, this time to the top right quadrant. In the second resize (if you don't have font-based resize handling turned on), the WM_SIZE handler code will find a path through the twisty maze of ifs on which the border between the text and the client-area edges is not recomputed, or invalidated, or redrawn. So you can end up with half a line of text from the previous window size still visible at the bottom of the new window. Fixed by factoring out the offset-recomputation code from the large and complicated reset_window(), so that I can call just that snippet on the dangerous code path.

Post-release destabilisation! Completely remove the struct type 'Config' in putty.h, which stores all PuTTY's settings and includes an arbitrary length limit on every single one of those settings which is stored in string form. In place of it is 'Conf', an opaque data type everywhere outside the new file conf.c, which stores a list of (key, value) pairs in which every key contains an integer identifying a configuration setting, and for some of those integers the key also contains extra parts (so that, for instance, CONF_environmt is a string-to-string mapping). Everywhere that a Config was previously used, a Conf is now; everywhere there was a Config structure copy, conf_copy() is called; every lookup, adjustment, load and save operation on a Config has been rewritten; and there's a mechanism for serialising a Conf into a binary blob and back for use with Duplicate Session. User-visible effects of this change _should_ be minimal, though I don't doubt I've introduced one or two bugs here and there which will eventually be found. The _intended_ visible effects of this change are that all arbitrary limits on configuration strings and lists (e.g. limit on number of port forwardings) should now disappear; that list boxes in the configuration will now be displayed in a sorted order rather than the arbitrary order in which they were added to the list (since the underlying data structure is now a sorted tree234 rather than an ad-hoc comma-separated string); and one more specific change, which is that local and dynamic port forwardings on the same port number are now mutually exclusive in the configuration (putting 'D' in the key rather than the value was a mistake in the first place). One other reorganisation as a result of this is that I've moved all the dialog.c standard handlers (dlg_stdeditbox_handler and friends) out into config.c, because I can't really justify calling them generic any more. When they took a pointer to an arbitrary structure type and the offset of a field within that structure, they were independent of whether that structure was a Config or something completely different, but now they really do expect to talk to a Conf, which can _only_ be used for PuTTY configuration, so I've renamed them all things like conf_editbox_handler and moved them out of the nominally independent dialog-box management module into the PuTTY-specific config.c.

Start using C99 variadic macros. In the past, I've had a lot of macros which you call with double parentheses, along the lines of debug(("format string", params)), so that the inner parens protect the commas and permit the macro to treat the whole printf-style argument list as one macro argument. That's all very well, but it's a bit inconvenient (it doesn't leave you any way to implement such a macro by prepending another argument to the list), and now this code base's rules allow C99isms, I can switch all those macros to using a single pair of parens, using the C99 ability to say '...' in the parameter list of the #define and get at the corresponding suffix of the arguments as __VA_ARGS__. So I'm doing it. I've made the following printf-style macros variadic: bpp_logevent, ppl_logevent, ppl_printf and debug. While I'm here, I've also fixed up a collection of conditioned-out calls to debug() in the Windows front end which were clearly expecting a macro with a different calling syntax, because they had an integer parameter first. If I ever have a need to condition those back in, they should actually work now.

GUI PuTTY: stop using the global 'hwnd'. This was the difficult part of cleaning up that global variable. The main Windows PuTTY GUI is split between source files, so that _does_ actually need to refer to the main window from multiple places. But all the places where windlg.c needed to use 'hwnd' are seat methods, so they were already receiving a Seat pointer as a parameter. In other words, the methods of the Windows GUI Seat were already split between source files. So it seems only fair that they should be able to share knowledge of the seat's data as well. Hence, I've created a small 'WinGuiSeat' structure which both window.c and windlg.c can see the layout of, and put the main terminal window handle in there.

GUI PuTTY: stop using the global 'hwnd'. This was the difficult part of cleaning up that global variable. The main Windows PuTTY GUI is split between source files, so that _does_ actually need to refer to the main window from multiple places. But all the places where windlg.c needed to use 'hwnd' are seat methods, so they were already receiving a Seat pointer as a parameter. In other words, the methods of the Windows GUI Seat were already split between source files. So it seems only fair that they should be able to share knowledge of the seat's data as well. Hence, I've created a small 'WinGuiSeat' structure which both window.c and windlg.c can see the layout of, and put the main terminal window handle in there. Then the seat methods implemented in windlg.c, like win_seat_verify_ssh_host_key, can use container_of to turn the Seat pointer parameter back into the address of that structure, just as the methods in window.c can do (even though they currently don't need to).

Post-release destabilisation! Completely remove the struct type 'Config' in putty.h, which stores all PuTTY's settings and includes an arbitrary length limit on every single one of those settings which is stored in string form. In place of it is 'Conf', an opaque data type everywhere outside the new file conf.c, which stores a list of (key, value) pairs in which every key contains an integer identifying a configuration setting, and for some of those integers the key also contains extra parts (so that, for instance, CONF_environmt is a string-to-string mapping). Everywhere that a Config was previously used, a Conf is now; everywhere there was a Config structure copy, conf_copy() is called; every lookup, adjustment, load and save operation on a Config has been rewritten; and there's a mechanism for serialising a Conf into a binary blob and back for use with Duplicate Session. User-visible effects of this change _should_ be minimal, though I don't doubt I've introduced one or two bugs here and there which will eventually be found. The _intended_ visible effects of this change are that all arbitrary limits on configuration strings and lists (e.g. limit on number of port forwardings) should now disappear; that list boxes in the configuration will now be displayed in a sorted order rather than the arbitrary order in which they were added to the list (since the underlying data structure is now a sorted tree234 rather than an ad-hoc comma-separated string); and one more specific change, which is that local and dynamic port forwardings on the same port number are now mutually exclusive in the configuration (putting 'D' in the key rather than the value was a mistake in the first place). One other reorganisation as a result of this is that I've moved all the dialog.c standard handlers (dlg_stdeditbox_handler and friends) out into config.c, because I can't really justify calling them generic any more. When they took a pointer to an arbitrary structure type and the offset of a field within that structure, they were independent of whether that structure was a Config or something completely different, but now they really do expect to talk to a Conf, which can _only_ be used for PuTTY configuration, so I've renamed them all things like conf_editbox_handler and moved them out of the nominally independent dialog-box management module into the PuTTY-specific config.c.

GUI PuTTY: stop using the global 'hwnd'. This was the difficult part of cleaning up that global variable. The main Windows PuTTY GUI is split between source files, so that _does_ actually need to refer to the main window from multiple places. But all the places where windlg.c needed to use 'hwnd' are seat methods, so they were already receiving a Seat pointer as a parameter. In other words, the methods of the Windows GUI Seat were already split between source files. So it seems only fair that they should be able to share knowledge of the seat's data as well. Hence, I've created a small 'WinGuiSeat' structure which both window.c and windlg.c can see the layout of, and put the main terminal window handle in there. Then the seat methods implemented in windlg.c, like win_seat_verify_ssh_host_key, can use container_of to turn the Seat pointer parameter back into the address of that structure, just as the methods in window.c can do (even though they currently don't need to). (Who knows: now that it _exists_, perhaps that structure can be gradually expanded in future to turn it into a proper encapsulation of all the Windows frontend's state, like we should have had all along...) I've also moved the Windows GUI LogPolicy implementation into the same object (i.e. WinGuiSeat implements both traits at once). That allows win_gui_logging_error to recover the same WinGuiSeat from its input LogPolicy pointer, which means it can get from there to the Seat facet of the same object, so that I don't need the extern variable 'win_seat' any more either.

Start using C99 variadic macros. In the past, I've had a lot of macros which you call with double parentheses, along the lines of debug(("format string", params)), so that the inner parens protect the commas and permit the macro to treat the whole printf-style argument list as one macro argument. That's all very well, but it's a bit inconvenient (it doesn't leave you any way to implement such a macro by prepending another argument to the list), and now this code base's rules allow C99isms, I can switch all those macros to using a single pair of parens, using the C99 ability to say '...' in the parameter list of the #define and get at the corresponding suffix of the arguments as __VA_ARGS__. So I'm doing it. I've made the following printf-style macros variadic: bpp_logevent, ppl_logevent, ppl_printf and debug. While I'm here, I've also fixed up a collection of conditioned-out calls to debug() in the Windows front end which were clearly expecting a macro with a different calling syntax, because they had an integer parameter first.

Convert a lot of 'int' variables to 'bool'. My normal habit these days, in new code, is to treat int and bool as _almost_ completely separate types. I'm still willing to use C's implicit test for zero on an integer (e.g. 'if (!blob.len)' is fine, no need to spell it out as blob.len != 0), but generally, if a variable is going to be conceptually a boolean, I like to declare it bool and assign to it using 'true' or 'false' rather than 0 or 1. PuTTY is an exception, because it predates the C99 bool, and I've stuck to its existing coding style even when adding new code to it. But it's been annoying me more and more, so now that I've decided C99 bool is an acceptable thing to require from our toolchain in the first place, here's a quite thorough trawl through the source doing 'boolification'. Many variables and function parameters are now typed as bool rather than int; many assignments of 0 or 1 to those variables are now spelled 'true' or 'false'. I managed this thorough conversion with the help of a custom clang plugin that I wrote to trawl the AST and apply heuristics to point out where things might want changing. So I've even managed to do a decent job on parts of the code I haven't looked at in years! To make the plugin's work easier, I pushed platform front ends generally in the direction of using standard 'bool' in preference to platform-specific boolean types like Windows BOOL or GTK's gboolean; I've left the platform booleans in places they _have_ to be for the platform APIs to work right, but variables only used by my own code have been converted wherever I found them. In a few places there are int values that look very like booleans in _most_ of the places they're used, but have a rarely-used third value, or a distinction between different nonzero values that most users don't care about. In these cases, I've _removed_ uses of 'true' and 'false' for the return values, to emphasise that there's something more subtle going on than a simple boolean answer: - the 'multisel' field in dialog.h's list box structure, for which the GTK front end in particular recognises a difference between 1 and 2 but nearly everything else treats as boolean - the 'urgent' parameter to plug_receive, where 1 vs 2 tells you something about the specific location of the urgent pointer, but most clients only care about 0 vs 'something nonzero' - the return value of wc_match, where -1 indicates a syntax error in the wildcard. - the return values from SSH-1 RSA-key loading functions, which use -1 for 'wrong passphrase' and 0 for all other failures (so any caller which already knows it's not loading an _encrypted private_ key can treat them as boolean) - term->esc_query, and the 'query' parameter in toggle_mode in terminal.c, which _usually_ hold 0 for ESC[123h or 1 for ESC[?123h, but can also hold -1 for some other intervening character that we don't support. In a few places there's an integer that I haven't turned into a bool even though it really _can_ only take values 0 or 1 (and, as above, tried to make the call sites consistent in not calling those values true and false), on the grounds that I thought it would make it more confusing to imply that the 0 value was in some sense 'negative' or bad and the 1 positive or good: - the return value of plug_accepting uses the POSIXish convention of 0=success and nonzero=error; I think if I made it bool then I'd also want to reverse its sense, and that's a job for a separate piece of work. - the 'screen' parameter to lineptr() in terminal.c, where 0 and 1 represent the default and alternate screens. There's no obvious reason why one of those should be considered 'true' or 'positive' or 'success' - they're just indices - so I've left it as int. ssh_scp_recv had particularly confusing semantics for its previous int return value: its call sites used '<= 0' to check for error, but it never actually returned a negative number, just 0 or 1. Now the function and its call sites agree that it's a bool. In a couple of places I've renamed variables called 'ret', because I don't like that name any more - it's unclear whether it means the return value (in preparation) for the _containing_ function or the return value received from a subroutine call, and occasionally I've accidentally used the same variable for both and introduced a bug. So where one of those got in my way, I've renamed it to 'toret' or 'retd' (the latter short for 'returned') in line with my usual modern practice, but I haven't done a thorough job of finding all of them. Finally, one amusing side effect of doing this is that I've had to separate quite a few chained assignments. It used to be perfectly fine to write 'a = b = c = TRUE' when a,b,c were int and TRUE was just a the 'true' defined by stdbool.h, that idiom provokes a warning from gcc: 'suggest parentheses around assignment used as truth value'!

Post-release destabilisation! Completely remove the struct type 'Config' in putty.h, which stores all PuTTY's settings and includes an arbitrary length limit on every single one of those settings which is stored in string form. In place of it is 'Conf', an opaque data type everywhere outside the new file conf.c, which stores a list of (key, value) pairs in which every key contains an integer identifying a configuration setting, and for some of those integers the key also contains extra parts (so that, for instance, CONF_environmt is a string-to-string mapping). Everywhere that a Config was previously used, a Conf is now; everywhere there was a Config structure copy, conf_copy() is called; every lookup, adjustment, load and save operation on a Config has been rewritten; and there's a mechanism for serialising a Conf into a binary blob and back for use with Duplicate Session. User-visible effects of this change _should_ be minimal, though I don't doubt I've introduced one or two bugs here and there which will eventually be found. The _intended_ visible effects of this change are that all arbitrary limits on configuration strings and lists (e.g. limit on number of port forwardings) should now disappear; that list boxes in the configuration will now be displayed in a sorted order rather than the arbitrary order in which they were added to the list (since the underlying data structure is now a sorted tree234 rather than an ad-hoc comma-separated string); and one more specific change, which is that local and dynamic port forwardings on the same port number are now mutually exclusive in the configuration (putting 'D' in the key rather than the value was a mistake in the first place). One other reorganisation as a result of this is that I've moved all the dialog.c standard handlers (dlg_stdeditbox_handler and friends) out into config.c, because I can't really justify calling them generic any more. When they took a pointer to an arbitrary structure type and the offset of a field within that structure, they were independent of whether that structure was a Config or something completely different, but now they really do expect to talk to a Conf, which can _only_ be used for PuTTY configuration, so I've renamed them all things like conf_editbox_handler and moved them out of the nominally independent dialog-box management module into the PuTTY-specific config.c.

Convert a lot of 'int' variables to 'bool'. My normal habit these days, in new code, is to treat int and bool as _almost_ completely separate types. I'm still willing to use C's implicit test for zero on an integer (e.g. 'if (!blob.len)' is fine, no need to spell it out as blob.len != 0), but generally, if a variable is going to be conceptually a boolean, I like to declare it bool and assign to it using 'true' or 'false' rather than 0 or 1. PuTTY is an exception, because it predates the C99 bool, and I've stuck to its existing coding style even when adding new code to it. But it's been annoying me more and more, so now that I've decided C99 bool is an acceptable thing to require from our toolchain in the first place, here's a quite thorough trawl through the source doing 'boolification'. Many variables and function parameters are now typed as bool rather than int; many assignments of 0 or 1 to those variables are now spelled 'true' or 'false'. I managed this thorough conversion with the help of a custom clang plugin that I wrote to trawl the AST and apply heuristics to point out where things might want changing. So I've even managed to do a decent job on parts of the code I haven't looked at in years! To make the plugin's work easier, I pushed platform front ends generally in the direction of using standard 'bool' in preference to platform-specific boolean types like Windows BOOL or GTK's gboolean; I've left the platform booleans in places they _have_ to be for the platform APIs to work right, but variables only used by my own code have been converted wherever I found them. In a few places there are int values that look very like booleans in _most_ of the places they're used, but have a rarely-used third value, or a distinction between different nonzero values that most users don't care about. In these cases, I've _removed_ uses of 'true' and 'false' for the return values, to emphasise that there's something more subtle going on than a simple boolean answer: - the 'multisel' field in dialog.h's list box structure, for which the GTK front end in particular recognises a difference between 1 and 2 but nearly everything else treats as boolean - the 'urgent' parameter to plug_receive, where 1 vs 2 tells you something about the specific location of the urgent pointer, but most clients only care about 0 vs 'something nonzero' - the return value of wc_match, where -1 indicates a syntax error in the wildcard. - the return values from SSH-1 RSA-key loading functions, which use -1 for 'wrong passphrase' and 0 for all other failures (so any caller which already knows it's not loading an _encrypted private_ key can treat them as boolean) - term->esc_query, and the 'query' parameter in toggle_mode in terminal.c, which _usually_ hold 0 for ESC[123h or 1 for ESC[?123h, but can also hold -1 for some other intervening character that we don't support. In a few places there's an integer that I haven't turned into a bool even though it really _can_ only take values 0 or 1 (and, as above, tried to make the call sites consistent in not calling those values true and false), on the grounds that I thought it would make it more confusing to imply that the 0 value was in some sense 'negative' or bad and the 1 positive or good: - the return value of plug_accepting uses the POSIXish convention of 0=success and nonzero=error; I think if I made it bool then I'd also want to reverse its sense, and that's a job for a separate piece of work. - the 'screen' parameter to lineptr() in terminal.c, where 0 and 1 represent the default and alternate screens. There's no obvious reason why one of those should be considered 'true' or 'positive' or 'success' - they're just indices - so I've left it as int. ssh_scp_recv had particularly confusing semantics for its previous int return value: its call sites used '<= 0' to check for error, but it never actually returned a negative number, just 0 or 1. Now the function and its call sites agree that it's a bool. In a couple of places I've renamed variables called 'ret', because I don't like that name any more - it's unclear whether it means the return value (in preparation) for the _containing_ function or the return value received from a subroutine call, and occasionally I've accidentally used the same variable for both and introduced a bug. So where one of those got in my way, I've renamed it to 'toret' or 'retd' (the latter short for 'returned') in line with my usual modern practice, but I haven't done a thorough job of finding all of them. Finally, one amusing side effect of doing this is that I've had to separate quite a few chained assignments. It used to be perfectly fine to write 'a = b = c = TRUE' when a,b,c were int and TRUE was just a the 'true' defined by stdbool.h, that idiom provokes a warning from gcc: 'suggest parentheses around assignment used as truth value'!

The terminal window can now indicate that PuTTY is busy in various ways, by changing its mouse pointer. Currently this is only used in the (slightly- arbitrarily-defined) "heavy" bits of SSH-2 key exchange. We override pointer hiding while PuTTY is busy, but preserve pointer-hiding state.

Switch some Conf settings over to being bool. I think this is the full set of things that ought logically to be boolean. One annoyance is that quite a few radio-button controls in config.c address Conf fields that are now bool rather than int, which means that the shared handler function can't just access them all with conf_{get,set}_int. Rather than back out the rigorous separation of int and bool in conf.c itself, I've just added a similar alternative handler function for the bool-typed ones.

The number of people has been steadily increasing who read our source code with an editor that thinks tab stops are 4 spaces apart, as opposed to the traditional tty-derived 8 that the PuTTY code expects. So I've been wondering for ages about just fixing it, and switching to a spaces-only policy throughout the code. And I recently found out about 'git blame -w', which should make this change not too disruptive for the purposes of source-control archaeology; so perhaps now is the time. While I'm at it, I've also taken the opportunity to remove all the trailing spaces from source lines (on the basis that git dislikes them, and is the only thing that seems to have a strong opinion one way or the other). Apologies to anyone downstream of this code who has complicated patch sets to rebase past this change. I don't intend it to be needed again.

Adopt C99 <stdbool.h>'s true/false. This commit includes <stdbool.h> from defs.h and deletes my traditional definitions of TRUE and FALSE, but other than that, it's a 100% mechanical search-and-replace transforming all uses of TRUE and FALSE into the C99-standardised lowercase spellings. No actual types are changed in this commit; that will come next. This is just getting the noise out of the way, so that subsequent commits can have a higher proportion of signal.

Convert a lot of 'int' variables to 'bool'. My normal habit these days, in new code, is to treat int and bool as _almost_ completely separate types. I'm still willing to use C's implicit test for zero on an integer (e.g. 'if (!blob.len)' is fine, no need to spell it out as blob.len != 0), but generally, if a variable is going to be conceptually a boolean, I like to declare it bool and assign to it using 'true' or 'false' rather than 0 or 1. PuTTY is an exception, because it predates the C99 bool, and I've stuck to its existing coding style even when adding new code to it. But it's been annoying me more and more, so now that I've decided C99 bool is an acceptable thing to require from our toolchain in the first place, here's a quite thorough trawl through the source doing 'boolification'. Many variables and function parameters are now typed as bool rather than int; many assignments of 0 or 1 to those variables are now spelled 'true' or 'false'. I managed this thorough conversion with the help of a custom clang plugin that I wrote to trawl the AST and apply heuristics to point out where things might want changing. So I've even managed to do a decent job on parts of the code I haven't looked at in years! To make the plugin's work easier, I pushed platform front ends generally in the direction of using standard 'bool' in preference to platform-specific boolean types like Windows BOOL or GTK's gboolean; I've left the platform booleans in places they _have_ to be for the platform APIs to work right, but variables only used by my own code have been converted wherever I found them. In a few places there are int values that look very like booleans in _most_ of the places they're used, but have a rarely-used third value, or a distinction between different nonzero values that most users don't care about. In these cases, I've _removed_ uses of 'true' and 'false' for the return values, to emphasise that there's something more subtle going on than a simple boolean answer: - the 'multisel' field in dialog.h's list box structure, for which the GTK front end in particular recognises a difference between 1 and 2 but nearly everything else treats as boolean - the 'urgent' parameter to plug_receive, where 1 vs 2 tells you something about the specific location of the urgent pointer, but most clients only care about 0 vs 'something nonzero' - the return value of wc_match, where -1 indicates a syntax error in the wildcard. - the return values from SSH-1 RSA-key loading functions, which use -1 for 'wrong passphrase' and 0 for all other failures (so any caller which already knows it's not loading an _encrypted private_ key can treat them as boolean) - term->esc_query, and the 'query' parameter in toggle_mode in terminal.c, which _usually_ hold 0 for ESC[123h or 1 for ESC[?123h, but can also hold -1 for some other intervening character that we don't support. In a few places there's an integer that I haven't turned into a bool even though it really _can_ only take values 0 or 1 (and, as above, tried to make the call sites consistent in not calling those values true and false), on the grounds that I thought it would make it more confusing to imply that the 0 value was in some sense 'negative' or bad and the 1 positive or good: - the return value of plug_accepting uses the POSIXish convention of 0=success and nonzero=error; I think if I made it bool then I'd also want to reverse its sense, and that's a job for a separate piece of work. - the 'screen' parameter to lineptr() in terminal.c, where 0 and 1 represent the default and alternate screens. There's no obvious reason why one of those should be considered 'true' or 'positive' or 'success' - they're just indices - so I've left it as int. ssh_scp_recv had particularly confusing semantics for its previous int return value: its call sites used '<= 0' to check for error, but it never actually returned a negative number, just 0 or 1. Now the function and its call sites agree that it's a bool. In a couple of places I've renamed variables called 'ret', because I don't like that name any more - it's unclear whether it means the return value (in preparation) for the _containing_ function or the return value received from a subroutine call, and occasionally I've accidentally used the same variable for both and introduced a bug. So where one of those got in my way, I've renamed it to 'toret' or 'retd' (the latter short for 'returned') in line with my usual modern practice, but I haven't done a thorough job of finding all of them. Finally, one amusing side effect of doing this is that I've had to separate quite a few chained assignments. It used to be perfectly fine to write 'a = b = c = TRUE' when a,b,c were int and TRUE was just a the 'true' defined by stdbool.h, that idiom provokes a warning from gcc: 'suggest parentheses around assignment used as truth value'!

Missing are ESC[4;X;Yt (resize to a specified pixel size; our resize code doesn't like it) and ESC[19;X;Yt (report size of _screen_ in _characters_, which it isn't even obvious how to do when you've got a variable font size).

New abstraction 'Seat', to pass to backends. This is a new vtable-based abstraction which is passed to a backend in place of Frontend, and it implements only the subset of the Frontend functions needed by a backend. (Many other Frontend functions still exist, notably the wide range of things called by terminal.c providing platform-independent operations on the GUI terminal window.) The purpose of making it a vtable is that this opens up the possibility of creating a backend as an internal implementation detail of some other activity, by providing just that one backend with a custom Seat that implements the methods differently. For example, this refactoring should make it feasible to directly implement an SSH proxy type, aka the 'jump host' feature supported by OpenSSH, aka 'open a secondary SSH session in MAINCHAN_DIRECT_TCP mode, and then expose the main channel of that as the Socket for the primary connection'. (Which of course you can already do by spawning 'plink -nc' as a separate proxy process, but this would permit it in the _same_ process without anything getting confused.) I've centralised a full set of stub methods in misc.c for the new abstraction, which allows me to get rid of several annoying stubs in the previous code. Also, while I'm here, I've moved a lot of duplicated modalfatalbox() type functions from application main program files into wincons.c / uxcons.c, which I think saves duplication overall. (A minor visible effect is that the prefixes on those console-based fatal error messages will now be more consistent between applications.)

Post-release destabilisation! Completely remove the struct type 'Config' in putty.h, which stores all PuTTY's settings and includes an arbitrary length limit on every single one of those settings which is stored in string form. In place of it is 'Conf', an opaque data type everywhere outside the new file conf.c, which stores a list of (key, value) pairs in which every key contains an integer identifying a configuration setting, and for some of those integers the key also contains extra parts (so that, for instance, CONF_environmt is a string-to-string mapping). Everywhere that a Config was previously used, a Conf is now; everywhere there was a Config structure copy, conf_copy() is called; every lookup, adjustment, load and save operation on a Config has been rewritten; and there's a mechanism for serialising a Conf into a binary blob and back for use with Duplicate Session. User-visible effects of this change _should_ be minimal, though I don't doubt I've introduced one or two bugs here and there which will eventually be found. The _intended_ visible effects of this change are that all arbitrary limits on configuration strings and lists (e.g. limit on number of port forwardings) should now disappear; that list boxes in the configuration will now be displayed in a sorted order rather than the arbitrary order in which they were added to the list (since the underlying data structure is now a sorted tree234 rather than an ad-hoc comma-separated string); and one more specific change, which is that local and dynamic port forwardings on the same port number are now mutually exclusive in the configuration (putting 'D' in the key rather than the value was a mistake in the first place). One other reorganisation as a result of this is that I've moved all the dialog.c standard handlers (dlg_stdeditbox_handler and friends) out into config.c, because I can't really justify calling them generic any more. When they took a pointer to an arbitrary structure type and the offset of a field within that structure, they were independent of whether that structure was a Config or something completely different, but now they really do expect to talk to a Conf, which can _only_ be used for PuTTY configuration, so I've renamed them all things like conf_editbox_handler and moved them out of the nominally independent dialog-box management module into the PuTTY-specific config.c.

Turn Backend into a sensible classoid. Nearly every part of the code that ever handles a full backend structure has historically done it using a pair of pointer variables, one pointing at a constant struct full of function pointers, and the other pointing to a 'void *' state object that's passed to each of those. While I'm modernising the rest of the code, this seems like a good time to turn that into the same more or less type-safe and less cumbersome system as I'm using for other parts of the code, such as Socket, Plug, BinaryPacketProtocol and so forth: the Backend structure contains a vtable pointer, and a system of macro wrappers handles dispatching through that vtable.

GUI PuTTY: stop using the global 'hwnd'. This was the difficult part of cleaning up that global variable. The main Windows PuTTY GUI is split between source files, so that _does_ actually need to refer to the main window from multiple places. But all the places where windlg.c needed to use 'hwnd' are seat methods, so they were already receiving a Seat pointer as a parameter. In other words, the methods of the Windows GUI Seat were already split between source files. So it seems only fair that they should be able to share knowledge of the seat's data as well. Hence, I've created a small 'WinGuiSeat' structure which both window.c and windlg.c can see the layout of, and put the main terminal window handle in there. Then the seat methods implemented in windlg.c, like win_seat_verify_ssh_host_key, can use container_of to turn the Seat pointer parameter back into the address of that structure, just as the methods in window.c can do (even though they currently don't need to). (Who knows: now that it _exists_, perhaps that structure can be gradually expanded in future to turn it into a proper encapsulation of all the Windows frontend's state, like we should have had all along...) I've also moved the Windows GUI LogPolicy implementation into the same object (i.e. WinGuiSeat implements both traits at once). That allows win_gui_logging_error to recover the same WinGuiSeat from its input LogPolicy pointer, which means it can get from there to the Seat facet of the same object, so that I don't need the extern variable 'win_seat' any more either.

After the recent Seat and LogContext revamps, _nearly_ all the remaining uses of the type 'Frontend' were in terminal.c, which needs all sorts of interactions with the GUI window the terminal lives in, from the obvious (actually drawing text on the window, reading and writing the clipboard) to the obscure (minimising, maximising and moving the window in response to particular escape sequences). All of those functions are now provided by an abstraction called TermWin. The few remaining uses of Frontend after _that_ are internal to a particular platform directory, so as to spread the implementation of that particular kind of Frontend between multiple source files; so I've renamed all of those so that they take a more specifically named type that refers to the particular implementation rather than the general abstraction. So now the name 'Frontend' no longer exists in the code base at all, and everywhere one used to be used, it's completely clear whether it was operating in one of Frontend's three abstract roles (and if so, which), or whether it was specific to a particular implementation. Another type that's disappeared is 'Context', which used to be a typedef defined to something different on each platform, describing whatever short-lived resources were necessary to draw on the terminal window: the front end would provide a ready-made one when calling term_paint, and the terminal could request one with get_ctx/free_ctx if it wanted to do proactive window updates. Now that drawing context lives inside the TermWin itself, because there was never any need to have two of those contexts live at the same time.

GUI PuTTY: stop using the global 'hwnd'. This was the difficult part of cleaning up that global variable. The main Windows PuTTY GUI is split between source files, so that _does_ actually need to refer to the main window from multiple places. But all the places where windlg.c needed to use 'hwnd' are seat methods, so they were already receiving a Seat pointer as a parameter. In other words, the methods of the Windows GUI Seat were already split between source files. So it seems only fair that they should be able to share knowledge of the seat's data as well. Hence, I've created a small 'WinGuiSeat' structure which both window.c and windlg.c can see the layout of, and put the main terminal window handle in there. Then the seat methods implemented in windlg.c, like win_seat_verify_ssh_host_key, can use container_of to turn the Seat pointer parameter back into the address of that structure, just as the methods in window.c can do (even though they currently don't need to). (Who knows: now that it _exists_, perhaps that structure can be gradually expanded in future to turn it into a proper encapsulation of all the Windows frontend's state, like we should have had all along...) I've also moved the Windows GUI LogPolicy implementation into the same object (i.e. WinGuiSeat implements both traits at once). That allows win_gui_logging_error to recover the same WinGuiSeat from its input LogPolicy pointer, which means it can get from there to the Seat facet of the same object, so that I don't need the extern variable 'win_seat' any more either.

Windows: make the need_backend_resize mechanism consistent. There were three separate clauses in the WM_SIZE message handler which potentially called term_size() to resize the actual Terminal object. Two of them (for maximisation and normal non-maximised resizing drags) first checked if an interactive resize was in progress, and if so, instead set the need_backend_resize, to defer the term_size call to the end of the interactive operation. But the third, for _un_-maximising a window, didn't have that check. As a result, if you start with a maximised window, drag its title bar downward from the top of the screen (which unmaximises it), and without letting go, drag it back up again (which maximises it), the effect would be that you'd get one call to term_size in the middle of the drag, and a second at the end. This isn't what I intended, and it can also cause a redraw failure in full-screen applications on the server (such as a terminal-based text editor - I reproduced this with emacs), in which after the second term_size the terminal doesn't manage to redraw itself. Now I've pulled out the common logic that was in two of those three pieces of code (and should have been in all three) into a subroutine wm_size_resize_term, and arranged to call that in all three cases. This fixes the inconsistency, and also fixes the emacs redraw problem in the edge case I describe above.

Convert a lot of 'int' variables to 'bool'. My normal habit these days, in new code, is to treat int and bool as _almost_ completely separate types. I'm still willing to use C's implicit test for zero on an integer (e.g. 'if (!blob.len)' is fine, no need to spell it out as blob.len != 0), but generally, if a variable is going to be conceptually a boolean, I like to declare it bool and assign to it using 'true' or 'false' rather than 0 or 1. PuTTY is an exception, because it predates the C99 bool, and I've stuck to its existing coding style even when adding new code to it. But it's been annoying me more and more, so now that I've decided C99 bool is an acceptable thing to require from our toolchain in the first place, here's a quite thorough trawl through the source doing 'boolification'. Many variables and function parameters are now typed as bool rather than int; many assignments of 0 or 1 to those variables are now spelled 'true' or 'false'. I managed this thorough conversion with the help of a custom clang plugin that I wrote to trawl the AST and apply heuristics to point out where things might want changing. So I've even managed to do a decent job on parts of the code I haven't looked at in years! To make the plugin's work easier, I pushed platform front ends generally in the direction of using standard 'bool' in preference to platform-specific boolean types like Windows BOOL or GTK's gboolean; I've left the platform booleans in places they _have_ to be for the platform APIs to work right, but variables only used by my own code have been converted wherever I found them. In a few places there are int values that look very like booleans in _most_ of the places they're used, but have a rarely-used third value, or a distinction between different nonzero values that most users don't care about. In these cases, I've _removed_ uses of 'true' and 'false' for the return values, to emphasise that there's something more subtle going on than a simple boolean answer: - the 'multisel' field in dialog.h's list box structure, for which the GTK front end in particular recognises a difference between 1 and 2 but nearly everything else treats as boolean - the 'urgent' parameter to plug_receive, where 1 vs 2 tells you something about the specific location of the urgent pointer, but most clients only care about 0 vs 'something nonzero' - the return value of wc_match, where -1 indicates a syntax error in the wildcard. - the return values from SSH-1 RSA-key loading functions, which use -1 for 'wrong passphrase' and 0 for all other failures (so any caller which already knows it's not loading an _encrypted private_ key can treat them as boolean) - term->esc_query, and the 'query' parameter in toggle_mode in terminal.c, which _usually_ hold 0 for ESC[123h or 1 for ESC[?123h, but can also hold -1 for some other intervening character that we don't support. In a few places there's an integer that I haven't turned into a bool even though it really _can_ only take values 0 or 1 (and, as above, tried to make the call sites consistent in not calling those values true and false), on the grounds that I thought it would make it more confusing to imply that the 0 value was in some sense 'negative' or bad and the 1 positive or good: - the return value of plug_accepting uses the POSIXish convention of 0=success and nonzero=error; I think if I made it bool then I'd also want to reverse its sense, and that's a job for a separate piece of work. - the 'screen' parameter to lineptr() in terminal.c, where 0 and 1 represent the default and alternate screens. There's no obvious reason why one of those should be considered 'true' or 'positive' or 'success' - they're just indices - so I've left it as int. ssh_scp_recv had particularly confusing semantics for its previous int return value: its call sites used '<= 0' to check for error, but it never actually returned a negative number, just 0 or 1. Now the function and its call sites agree that it's a bool. In a couple of places I've renamed variables called 'ret', because I don't like that name any more - it's unclear whether it means the return value (in preparation) for the _containing_ function or the return value received from a subroutine call, and occasionally I've accidentally used the same variable for both and introduced a bug. So where one of those got in my way, I've renamed it to 'toret' or 'retd' (the latter short for 'returned') in line with my usual modern practice, but I haven't done a thorough job of finding all of them. Finally, one amusing side effect of doing this is that I've had to separate quite a few chained assignments. It used to be perfectly fine to write 'a = b = c = TRUE' when a,b,c were int and TRUE was just a the 'true' defined by stdbool.h, that idiom provokes a warning from gcc: 'suggest parentheses around assignment used as truth value'!

Post-release destabilisation! Completely remove the struct type 'Config' in putty.h, which stores all PuTTY's settings and includes an arbitrary length limit on every single one of those settings which is stored in string form. In place of it is 'Conf', an opaque data type everywhere outside the new file conf.c, which stores a list of (key, value) pairs in which every key contains an integer identifying a configuration setting, and for some of those integers the key also contains extra parts (so that, for instance, CONF_environmt is a string-to-string mapping). Everywhere that a Config was previously used, a Conf is now; everywhere there was a Config structure copy, conf_copy() is called; every lookup, adjustment, load and save operation on a Config has been rewritten; and there's a mechanism for serialising a Conf into a binary blob and back for use with Duplicate Session. User-visible effects of this change _should_ be minimal, though I don't doubt I've introduced one or two bugs here and there which will eventually be found. The _intended_ visible effects of this change are that all arbitrary limits on configuration strings and lists (e.g. limit on number of port forwardings) should now disappear; that list boxes in the configuration will now be displayed in a sorted order rather than the arbitrary order in which they were added to the list (since the underlying data structure is now a sorted tree234 rather than an ad-hoc comma-separated string); and one more specific change, which is that local and dynamic port forwardings on the same port number are now mutually exclusive in the configuration (putting 'D' in the key rather than the value was a mistake in the first place). One other reorganisation as a result of this is that I've moved all the dialog.c standard handlers (dlg_stdeditbox_handler and friends) out into config.c, because I can't really justify calling them generic any more. When they took a pointer to an arbitrary structure type and the offset of a field within that structure, they were independent of whether that structure was a Config or something completely different, but now they really do expect to talk to a Conf, which can _only_ be used for PuTTY configuration, so I've renamed them all things like conf_editbox_handler and moved them out of the nominally independent dialog-box management module into the PuTTY-specific config.c.

The number of people has been steadily increasing who read our source code with an editor that thinks tab stops are 4 spaces apart, as opposed to the traditional tty-derived 8 that the PuTTY code expects. So I've been wondering for ages about just fixing it, and switching to a spaces-only policy throughout the code. And I recently found out about 'git blame -w', which should make this change not too disruptive for the purposes of source-control archaeology; so perhaps now is the time. While I'm at it, I've also taken the opportunity to remove all the trailing spaces from source lines (on the basis that git dislikes them, and is the only thing that seems to have a strong opinion one way or the other). Apologies to anyone downstream of this code who has complicated patch sets to rebase past this change. I don't intend it to be needed again.

Formatting change to braces around one case of a switch. Sometimes, within a switch statement, you want to declare local variables specific to the handler for one particular case. Until now I've mostly been writing this in the form switch (discriminant) { case SIMPLE: do stuff; break; case COMPLICATED: { declare variables; do stuff; } break; } which is ugly because the two pieces of essentially similar code appear at different indent levels, and also inconvenient because you have less horizontal space available to write the complicated case handler in - particuarly undesirable because _complicated_ case handlers are the ones most likely to need all the space they can get! After encountering a rather nicer idiom in the LLVM source code, and after a bit of hackery this morning figuring out how to persuade Emacs's auto-indent to do what I wanted with it, I've decided to move to an idiom in which the open brace comes right after the case statement, and the code within it is indented the same as it would have been without the brace. Then the whole case handler (including the break) lives inside those braces, and you get something that looks more like this: switch (discriminant) { case SIMPLE: do stuff; break; case COMPLICATED: { declare variables; do stuff; break; } } This commit is a big-bang change that reformats all the complicated case handlers I could find into the new layout. This is particularly nice in the Pageant main function, in which almost _every_ case handler had a bundle of variables and was long and complicated. (In fact that's what motivated me to get round to this.) Some of the innermost parts of the terminal escape-sequence handling are also breathing a bit easier now the horizontal pressure on them is relieved. (Also, in a few cases, I was able to remove the extra braces completely, because the only variable local to the case handler was a loop variable which our new C99 policy allows me to move into the initialiser clause of its for statement.) Viewed with whitespace ignored, this is not too disruptive a change. Downstream patches that conflict with it may need to be reapplied using --ignore-whitespace or similar.

If a new session was saved from Change Settings, a side-effect on Windows was that the global `sesslist' got out of sync with the saved-sessions submenu, causing the latter to launch the wrong sessions. Also, Change Settings wasn't getting a fresh session list, so if the set of sessions had changed since session startup it wouldn't reflect that (at least until a session was saved). Fixed (on all platforms). Therefore, since the global sesslist didn't seem to be useful, I've got rid of it; config.c creates one as needed, as do the frontends. (Not tried compiling Mac changes.) Also, we now build the saved-sessions submenu on demand on Windows and Unix. (This should probably also be done on the Mac.) [originally from svn r5609]

And I recently found out about 'git blame -w', which should make this change not too disruptive for the purposes of source-control archaeology; so perhaps now is the time. While I'm at it, I've also taken the opportunity to remove all the trailing spaces from source lines (on the basis that git dislikes them, and is the only thing that seems to have a strong opinion one way or the other). Apologies to anyone downstream of this code who has complicated patch sets to rebase past this change. I don't intend it to be needed again.

case IDM_RESTART:
Turn Backend into a sensible classoid. Nearly every part of the code that ever handles a full backend structure has historically done it using a pair of pointer variables, one pointing at a constant struct full of function pointers, and the other pointing to a 'void *' state object that's passed to each of those. While I'm modernising the rest of the code, this seems like a good time to turn that into the same more or less type-safe and less cumbersome system as I'm using for other parts of the code, such as Socket, Plug, BinaryPacketProtocol and so forth: the Backend structure contains a vtable pointer, and a system of macro wrappers handles dispatching through that vtable.

GUI PuTTY: stop using the global 'hwnd'. This was the difficult part of cleaning up that global variable. The main Windows PuTTY GUI is split between source files, so that _does_ actually need to refer to the main window from multiple places. But all the places where windlg.c needed to use 'hwnd' are seat methods, so they were already receiving a Seat pointer as a parameter. In other words, the methods of the Windows GUI Seat were already split between source files. So it seems only fair that they should be able to share knowledge of the seat's data as well. Hence, I've created a small 'WinGuiSeat' structure which both window.c and windlg.c can see the layout of, and put the main terminal window handle in there. Then the seat methods implemented in windlg.c, like win_seat_verify_ssh_host_key, can use container_of to turn the Seat pointer parameter back into the address of that structure, just as the methods in window.c can do (even though they currently don't need to). (Who knows: now that it _exists_, perhaps that structure can be gradually expanded in future to turn it into a proper encapsulation of all the Windows frontend's state, like we should have had all along...) I've also moved the Windows GUI LogPolicy implementation into the same object (i.e. WinGuiSeat implements both traits at once). That allows win_gui_logging_error to recover the same WinGuiSeat from its input LogPolicy pointer, which means it can get from there to the Seat facet of the same object, so that I don't need the extern variable 'win_seat' any more either.

Formatting change to braces around one case of a switch. Sometimes, within a switch statement, you want to declare local variables specific to the handler for one particular case. Until now I've mostly been writing this in the form switch (discriminant) { case SIMPLE: do stuff; break; case COMPLICATED: { declare variables; do stuff; } break; } which is ugly because the two pieces of essentially similar code appear at different indent levels, and also inconvenient because you have less horizontal space available to write the complicated case handler in - particuarly undesirable because _complicated_ case handlers are the ones most likely to need all the space they can get! After encountering a rather nicer idiom in the LLVM source code, and after a bit of hackery this morning figuring out how to persuade Emacs's auto-indent to do what I wanted with it, I've decided to move to an idiom in which the open brace comes right after the case statement, and the code within it is indented the same as it would have been without the brace. Then the whole case handler (including the break) lives inside those braces, and you get something that looks more like this: switch (discriminant) { case SIMPLE: do stuff; break; case COMPLICATED: { declare variables; do stuff; break; } } This commit is a big-bang change that reformats all the complicated case handlers I could find into the new layout. This is particularly nice in the Pageant main function, in which almost _every_ case handler had a bundle of variables and was long and complicated.

Move all window-title management into Terminal. Previously, window title management happened in a bipartisan sort of way: front ends would choose their initial window title once they knew what host name they were connecting to, but then Terminal would override that later if the server set the window title by escape sequences. Now it's all done the same way round: the Terminal object is always where titles are invented, and they only propagate in one direction, from the Terminal to the TermWin. This allows us to avoid duplicating in multiple front ends the logic for what the initial window title should be. The frontend just has to make one initial call to term_setup_window_titles, to tell the terminal what hostname should go in the default title (if the Conf doesn't override even that). Thereafter, all it has to do is respond to the TermWin title-setting methods. Similarly, the logic that handles window-title changes as a result of the Change Settings dialog is also centralised into terminal.c. This involved introducing an extra term_pre_reconfig() call that each frontend can call to modify the Conf that will be used for the GUI configurer; that's where the code now lives that copies the current window title into there. (This also means that GTK PuTTY now behaves consistently with Windows PuTTY on that point; GTK's previous behaviour was less well thought out.) It also means there's no longer any need for Terminal to talk to the front end when a remote query wants to _find out_ the window title: the Terminal knows the answer already. So TermWin's get_title method can go.

Centralise palette setup into terminal.c. Now terminal.c makes nearly all the decisions about what the colour palette should actually contain: it does the job of reading the GUI-configurable colours out of Conf, and also the job of making up the rest of the xterm-256 palette. The only exception is that TermWin can provide a method to override some of the default colours, which on Windows is used to implement the 'Use system colours' config option. This saves code overall, partly because the front ends don't have to be able to send palette data back to the Terminal any more (the Terminal keeps the master copy and can answer palette-query escape sequences from its own knowledge), and also because now there's only one copy of the xterm-256 palette setup code (previously gtkwin.c and window.c each had their own version of it). In this rewrite, I've also introduced a multi-layered storage system for the palette data in Terminal. One layer contains the palette information derived from Conf; the next contains platform overrides (currently just Windows's 'Use system colours'); the last one contains overrides set by escape sequences in the middle of the session. The topmost two layers can each _conditionally_ override the ones below. As a result, if a server-side application manually resets (say) the default fg and bg colours in mid-session to something that works well in a particular application, those changes won't be wiped out by a change in the Windows system colours or the Conf, which they would have been before. Instead, changes in Conf or the system colours alter the lower layers of the structure, but then when palette_rebuild is called, the upper layer continues to override them, until a palette reset (ESC]R) or terminal reset (e.g. ESC c) removes those upper-layer changes. This seems like a more consistent strategy, in that the same set of configuration settings will produce the same end result regardless of what order they were applied in. The palette-related methods in TermWin have had a total rework. palette_get and palette_reset are both gone; palette_set can now set a contiguous range of colours in one go; and the new palette_get_overrides replaces window.c's old systopalette().

Then the whole case handler (including the break) lives inside those braces, and you get something that looks more like this: switch (discriminant) { case SIMPLE: do stuff; break; case COMPLICATED: { declare variables; do stuff; break; } } This commit is a big-bang change that reformats all the complicated case handlers I could find into the new layout. This is particularly nice in the Pageant main function, in which almost _every_ case handler had a bundle of variables and was long and complicated. (In fact that's what motivated me to get round to this.) Some of the innermost parts of the terminal escape-sequence handling are also breathing a bit easier now the horizontal pressure on them is relieved. (Also, in a few cases, I was able to remove the extra braces completely, because the only variable local to the case handler was a loop variable which our new C99 policy allows me to move into the initialiser clause of its for statement.)

Turn Backend into a sensible classoid. Nearly every part of the code that ever handles a full backend structure has historically done it using a pair of pointer variables, one pointing at a constant struct full of function pointers, and the other pointing to a 'void *' state object that's passed to each of those. While I'm modernising the rest of the code, this seems like a good time to turn that into the same more or less type-safe and less cumbersome system as I'm using for other parts of the code, such as Socket, Plug, BinaryPacketProtocol and so forth: the Backend structure contains a vtable pointer, and a system of macro wrappers handles dispatching through that vtable.

if (backend)
Rework special-commands system to add an integer argument. In order to list cross-certifiable host keys in the GUI specials menu, the SSH backend has been inventing new values on the end of the Telnet_Special enumeration, starting from the value TS_LOCALSTART. This is inelegant, and also makes it awkward to break up special handlers (e.g. to dispatch different specials to different SSH layers), since if all you know about a special is that it's somewhere in the TS_LOCALSTART+n space, you can't tell what _general kind_ of thing it is. Also, if I ever need another open-ended set of specials in future, I'll have to remember which TS_LOCALSTART+n codes are in which set. So here's a revamp that causes every special to take an extra integer argument. For all previously numbered specials, this argument is passed as zero and ignored, but there's a new main special code for SSH host key cross-certification, in which the integer argument is an index into the backend's list of available keys. TS_LOCALSTART is now a thing of the past: if I need any other open-ended sets of specials in future, I can add a new top-level code with a nicely separated space of arguments. While I'm at it, I've removed the legacy misnomer 'Telnet_Special' from the code completely; the enum is now SessionSpecialCode, the struct containing full details of a menu entry is SessionSpecial, and the enum values now start SS_ rather than TS_.

Convert a lot of 'int' variables to 'bool'. My normal habit these days, in new code, is to treat int and bool as _almost_ completely separate types. I'm still willing to use C's implicit test for zero on an integer (e.g. 'if (!blob.len)' is fine, no need to spell it out as blob.len != 0), but generally, if a variable is going to be conceptually a boolean, I like to declare it bool and assign to it using 'true' or 'false' rather than 0 or 1. PuTTY is an exception, because it predates the C99 bool, and I've stuck to its existing coding style even when adding new code to it. But it's been annoying me more and more, so now that I've decided C99 bool is an acceptable thing to require from our toolchain in the first place, here's a quite thorough trawl through the source doing 'boolification'. Many variables and function parameters are now typed as bool rather than int; many assignments of 0 or 1 to those variables are now spelled 'true' or 'false'. I managed this thorough conversion with the help of a custom clang plugin that I wrote to trawl the AST and apply heuristics to point out where things might want changing. So I've even managed to do a decent job on parts of the code I haven't looked at in years! To make the plugin's work easier, I pushed platform front ends generally in the direction of using standard 'bool' in preference to platform-specific boolean types like Windows BOOL or GTK's gboolean; I've left the platform booleans in places they _have_ to be for the platform APIs to work right, but variables only used by my own code have been converted wherever I found them. In a few places there are int values that look very like booleans in _most_ of the places they're used, but have a rarely-used third value, or a distinction between different nonzero values that most users don't care about. In these cases, I've _removed_ uses of 'true' and 'false' for the return values, to emphasise that there's something more subtle going on than a simple boolean answer: - the 'multisel' field in dialog.h's list box structure, for which the GTK front end in particular recognises a difference between 1 and 2 but nearly everything else treats as boolean - the 'urgent' parameter to plug_receive, where 1 vs 2 tells you something about the specific location of the urgent pointer, but most clients only care about 0 vs 'something nonzero' - the return value of wc_match, where -1 indicates a syntax error in the wildcard. - the return values from SSH-1 RSA-key loading functions, which use -1 for 'wrong passphrase' and 0 for all other failures (so any caller which already knows it's not loading an _encrypted private_ key can treat them as boolean) - term->esc_query, and the 'query' parameter in toggle_mode in terminal.c, which _usually_ hold 0 for ESC[123h or 1 for ESC[?123h, but can also hold -1 for some other intervening character that we don't support. In a few places there's an integer that I haven't turned into a bool even though it really _can_ only take values 0 or 1 (and, as above, tried to make the call sites consistent in not calling those values true and false), on the grounds that I thought it would make it more confusing to imply that the 0 value was in some sense 'negative' or bad and the 1 positive or good: - the return value of plug_accepting uses the POSIXish convention of 0=success and nonzero=error; I think if I made it bool then I'd also want to reverse its sense, and that's a job for a separate piece of work. - the 'screen' parameter to lineptr() in terminal.c, where 0 and 1 represent the default and alternate screens. There's no obvious reason why one of those should be considered 'true' or 'positive' or 'success' - they're just indices - so I've left it as int. ssh_scp_recv had particularly confusing semantics for its previous int return value: its call sites used '<= 0' to check for error, but it never actually returned a negative number, just 0 or 1. Now the function and its call sites agree that it's a bool. In a couple of places I've renamed variables called 'ret', because I don't like that name any more - it's unclear whether it means the return value (in preparation) for the _containing_ function or the return value received from a subroutine call, and occasionally I've accidentally used the same variable for both and introduced a bug. So where one of those got in my way, I've renamed it to 'toret' or 'retd' (the latter short for 'returned') in line with my usual modern practice, but I haven't done a thorough job of finding all of them. Finally, one amusing side effect of doing this is that I've had to separate quite a few chained assignments. It used to be perfectly fine to write 'a = b = c = TRUE' when a,b,c were int and TRUE was just a the 'true' defined by stdbool.h, that idiom provokes a warning from gcc: 'suggest parentheses around assignment used as truth value'!

Formatting change to braces around one case of a switch. Sometimes, within a switch statement, you want to declare local variables specific to the handler for one particular case. Until now I've mostly been writing this in the form switch (discriminant) { case SIMPLE: do stuff; break; case COMPLICATED: { declare variables; do stuff; } break; } which is ugly because the two pieces of essentially similar code appear at different indent levels, and also inconvenient because you have less horizontal space available to write the complicated case handler in - particuarly undesirable because _complicated_ case handlers are the ones most likely to need all the space they can get! After encountering a rather nicer idiom in the LLVM source code, and after a bit of hackery this morning figuring out how to persuade Emacs's auto-indent to do what I wanted with it, I've decided to move to an idiom in which the open brace comes right after the case statement, and the code within it is indented the same as it would have been without the brace. Then the whole case handler (including the break) lives inside those braces, and you get something that looks more like this: switch (discriminant) { case SIMPLE: do stuff; break; case COMPLICATED: { declare variables; do stuff; break; } } This commit is a big-bang change that reformats all the complicated case handlers I could find into the new layout. This is particularly nice in the Pageant main function, in which almost _every_ case handler had a bundle of variables and was long and complicated. (In fact that's what motivated me to get round to this.) Some of the innermost parts of the terminal escape-sequence handling are also breathing a bit easier now the horizontal pressure on them is relieved. (Also, in a few cases, I was able to remove the extra braces completely, because the only variable local to the case handler was a loop variable which our new C99 policy allows me to move into the initialiser clause of its for statement.) Viewed with whitespace ignored, this is not too disruptive a change. Downstream patches that conflict with it may need to be reapplied using --ignore-whitespace or similar.

Formatting change to braces around one case of a switch. Sometimes, within a switch statement, you want to declare local variables specific to the handler for one particular case. Until now I've mostly been writing this in the form switch (discriminant) { case SIMPLE: do stuff; break; case COMPLICATED: { declare variables; do stuff; } break; } which is ugly because the two pieces of essentially similar code appear at different indent levels, and also inconvenient because you have less horizontal space available to write the complicated case handler in - particuarly undesirable because _complicated_ case handlers are the ones most likely to need all the space they can get! After encountering a rather nicer idiom in the LLVM source code, and after a bit of hackery this morning figuring out how to persuade Emacs's auto-indent to do what I wanted with it, I've decided to move to an idiom in which the open brace comes right after the case statement, and the code within it is indented the same as it would have been without the brace. Then the whole case handler (including the break) lives inside those braces, and you get something that looks more like this: switch (discriminant) { case SIMPLE: do stuff; break; case COMPLICATED: { declare variables; do stuff; break; } } This commit is a big-bang change that reformats all the complicated case handlers I could find into the new layout. This is particularly nice in the Pageant main function, in which almost _every_ case handler had a bundle of variables and was long and complicated. (In fact that's what motivated me to get round to this.) Some of the innermost parts of the terminal escape-sequence handling are also breathing a bit easier now the horizontal pressure on them is relieved. (Also, in a few cases, I was able to remove the extra braces completely, because the only variable local to the case handler was a loop variable which our new C99 policy allows me to move into the initialiser clause of its for statement.) Viewed with whitespace ignored, this is not too disruptive a change. Downstream patches that conflict with it may need to be reapplied using --ignore-whitespace or similar.

/*
* We have to be careful about term_paint(). It will
* set a bunch of character cells to INVALID and then
* call do_paint(), which will redraw those cells and
* _then mark them as done_. This may not be accurate:
* when painting in WM_PAINT context we are restricted
* to the rectangle which has just been exposed - so if
* that only covers _part_ of a character cell and the
* rest of it was already visible, that remainder will
* not be redrawn at all. Accordingly, we must not
* paint any character cell in a WM_PAINT context which
* already has a pending update due to terminal output.
* The simplest solution to this - and many, many
* thanks to Hung-Te Lin for working all this out - is
* not to do any actual painting at _all_ if there's a
* pending terminal update: just mark the relevant
* character cells as INVALID and wait for the
* scheduled full update to sort it out.
*
* I have a suspicion this isn't the _right_ solution.
* An alternative approach would be to have terminal.c
* separately track what _should_ be on the terminal
* screen and what _is_ on the terminal screen, and
* have two completely different types of redraw (one
* for full updates, which syncs the former with the
* terminal itself, and one for WM_PAINT which syncs
* the latter with the former); yet another possibility
* would be to have the Windows front end do what the
* GTK one already does, and maintain a bitmap of the
* current terminal appearance so that WM_PAINT becomes
* completely trivial. However, this should do for now.

Add another missing window-border recalculation. This one is triggered by the following sequence: - fill up the terminal window with text ('ls -l /dev' or similar) - Win+Right then Win+Up to snap to the top right quadrant - interactively drag away from the top right quadrant with the title bar, which returns the window to its pre-snap size. After the snap, the window border will have been recomputed to take account of the window size not being an integer number of character cells. So it needs recomputing back again the next time the window size changes to something that _is_ an integer number - which happens (or rather, we process it in a deferred manner) at the EXITSIZEMOVE. So that's where we need to recompute the border (again).

Post-release destabilisation! Completely remove the struct type 'Config' in putty.h, which stores all PuTTY's settings and includes an arbitrary length limit on every single one of those settings which is stored in string form. In place of it is 'Conf', an opaque data type everywhere outside the new file conf.c, which stores a list of (key, value) pairs in which every key contains an integer identifying a configuration setting, and for some of those integers the key also contains extra parts (so that, for instance, CONF_environmt is a string-to-string mapping). Everywhere that a Config was previously used, a Conf is now; everywhere there was a Config structure copy, conf_copy() is called; every lookup, adjustment, load and save operation on a Config has been rewritten; and there's a mechanism for serialising a Conf into a binary blob and back for use with Duplicate Session. User-visible effects of this change _should_ be minimal, though I don't doubt I've introduced one or two bugs here and there which will eventually be found. The _intended_ visible effects of this change are that all arbitrary limits on configuration strings and lists (e.g. limit on number of port forwardings) should now disappear; that list boxes in the configuration will now be displayed in a sorted order rather than the arbitrary order in which they were added to the list (since the underlying data structure is now a sorted tree234 rather than an ad-hoc comma-separated string); and one more specific change, which is that local and dynamic port forwardings on the same port number are now mutually exclusive in the configuration (putting 'D' in the key rather than the value was a mistake in the first place). One other reorganisation as a result of this is that I've moved all the dialog.c standard handlers (dlg_stdeditbox_handler and friends) out into config.c, because I can't really justify calling them generic any more. When they took a pointer to an arbitrary structure type and the offset of a field within that structure, they were independent of whether that structure was a Config or something completely different, but now they really do expect to talk to a Conf, which can _only_ be used for PuTTY configuration, so I've renamed them all things like conf_editbox_handler and moved them out of the nominally independent dialog-box management module into the PuTTY-specific config.c.

Start using C99 variadic macros. In the past, I've had a lot of macros which you call with double parentheses, along the lines of debug(("format string", params)), so that the inner parens protect the commas and permit the macro to treat the whole printf-style argument list as one macro argument. That's all very well, but it's a bit inconvenient (it doesn't leave you any way to implement such a macro by prepending another argument to the list), and now this code base's rules allow C99isms, I can switch all those macros to using a single pair of parens, using the C99 ability to say '...' in the parameter list of the #define and get at the corresponding suffix of the arguments as __VA_ARGS__. So I'm doing it. I've made the following printf-style macros variadic: bpp_logevent, ppl_logevent, ppl_printf and debug. While I'm here, I've also fixed up a collection of conditioned-out calls to debug() in the Windows front end which were clearly expecting a macro with a different calling syntax, because they had an integer parameter first. If I ever have a need to condition those back in, they should actually work now.

Remove TermWin's is_minimised method. Again, I've replaced it with a push-based notification going in the other direction, so that when the terminal output stream includes a query for 'is the window minimised?', the Terminal doesn't have to consult the TermWin, because it already knows the answer. The GTK API I'm using here (getting a GdkEventWindowState via GtkWidget's window-state-event) is not present in GTK 1. The API I was previously using (gdk_window_is_viewable) _is_, but it turns out that that API doesn't reliably give the right answer: it only checks visibility of GDK window ancestors, not X window ancestors. So in fact GTK 1 PuTTY/pterm was only ever _pretending_ to reliably support the 'am I minimised' terminal query. Now it won't pretend any more.

Fix resize handling when enabling and disabling full-screen mode. I'm not sure whether I broke this in the recent revamp or whether it was always broken, but: transitions in and out of full-screen mode work by first maximising or restoring the window, which triggers a WM_SIZE, whose handler then fiddles with the window style to disable or re-enable all the furniture, which in turn triggers a recursive WM_SIZE. The trouble is, after returning from the handler for the inner WM_SIZE, the rest of the outer handler runs, and its client area size is now out of date. So I've added a flag which is set when a resize is handled 'properly', so that after returning from the inner WM_SIZE handler the outer one knows not to try to redo badly work that's already been done well.

Adopt C99 <stdbool.h>'s true/false. This commit includes <stdbool.h> from defs.h and deletes my traditional definitions of TRUE and FALSE, but other than that, it's a 100% mechanical search-and-replace transforming all uses of TRUE and FALSE into the C99-standardised lowercase spellings. No actual types are changed in this commit; that will come next. This is just getting the noise out of the way, so that subsequent commits can have a higher proportion of signal.

Fix resize handling when enabling and disabling full-screen mode. I'm not sure whether I broke this in the recent revamp or whether it was always broken, but: transitions in and out of full-screen mode work by first maximising or restoring the window, which triggers a WM_SIZE, whose handler then fiddles with the window style to disable or re-enable all the furniture, which in turn triggers a recursive WM_SIZE. The trouble is, after returning from the handler for the inner WM_SIZE, the rest of the outer handler runs, and its client area size is now out of date. So I've added a flag which is set when a resize is handled 'properly', so that after returning from the inner WM_SIZE handler the outer one knows not to try to redo badly work that's already been done well.

Whitespace rationalisation of entire code base. The number of people has been steadily increasing who read our source code with an editor that thinks tab stops are 4 spaces apart, as opposed to the traditional tty-derived 8 that the PuTTY code expects. So I've been wondering for ages about just fixing it, and switching to a spaces-only policy throughout the code. And I recently found out about 'git blame -w', which should make this change not too disruptive for the purposes of source-control archaeology; so perhaps now is the time. While I'm at it, I've also taken the opportunity to remove all the trailing spaces from source lines (on the basis that git dislikes them, and is the only thing that seems to have a strong opinion one way or the other). Apologies to anyone downstream of this code who has complicated patch sets to rebase past this change. I don't intend it to be needed again.

Windows: fix resizing of a maximised window. The RESIZE_EITHER resizing mode responds to a window resize by changing the logical terminal size if the window is shown normally, or by changing the font size to keep the terminal size the same if the resize is a transition between normal and maximised state. But a user pointed out that it's also possible for a window to receive a WM_SIZE message while _remaining_ in maximised state, and that PuTTY's resize logic didn't allow for that possibility. It occurs when there's a change in the amount of available screen space for the window to be maximised _in_: e.g. when the video resolution is reconfigured, or when you reconnect to a Remote Desktop session using a client window of a different size, or even when you toggle the 'Automatically hide the taskbar' option in the Windows taskbar settings. In that situation, the right thing seems to be for PuTTY to continue to go with the policy of changing the font size rather than the logical terminal size. In other words, we prefer to change the font size when the resize is _from_ maximised state, _to_ maximised state, _or both_. That's easily implemented by removing the check of the 'was_zoomed' flag, in the case where we've received a WM_SIZE message with the state SIZE_MAXIMIZED: once we know the transition is _to_ maximised state, it doesn't matter whether or not it was also _from_ it. (But we still set the was_zoomed flag to the most recent maximised status, so that we can recognise transitions _out_ of maximised mode.)

Convert a lot of 'int' variables to 'bool'. My normal habit these days, in new code, is to treat int and bool as _almost_ completely separate types. I'm still willing to use C's implicit test for zero on an integer (e.g. 'if (!blob.len)' is fine, no need to spell it out as blob.len != 0), but generally, if a variable is going to be conceptually a boolean, I like to declare it bool and assign to it using 'true' or 'false' rather than 0 or 1. PuTTY is an exception, because it predates the C99 bool, and I've stuck to its existing coding style even when adding new code to it. But it's been annoying me more and more, so now that I've decided C99 bool is an acceptable thing to require from our toolchain in the first place, here's a quite thorough trawl through the source doing 'boolification'. Many variables and function parameters are now typed as bool rather than int; many assignments of 0 or 1 to those variables are now spelled 'true' or 'false'. I managed this thorough conversion with the help of a custom clang plugin that I wrote to trawl the AST and apply heuristics to point out where things might want changing. So I've even managed to do a decent job on parts of the code I haven't looked at in years! To make the plugin's work easier, I pushed platform front ends generally in the direction of using standard 'bool' in preference to platform-specific boolean types like Windows BOOL or GTK's gboolean; I've left the platform booleans in places they _have_ to be for the platform APIs to work right, but variables only used by my own code have been converted wherever I found them. In a few places there are int values that look very like booleans in _most_ of the places they're used, but have a rarely-used third value, or a distinction between different nonzero values that most users don't care about. In these cases, I've _removed_ uses of 'true' and 'false' for the return values, to emphasise that there's something more subtle going on than a simple boolean answer: - the 'multisel' field in dialog.h's list box structure, for which the GTK front end in particular recognises a difference between 1 and 2 but nearly everything else treats as boolean - the 'urgent' parameter to plug_receive, where 1 vs 2 tells you something about the specific location of the urgent pointer, but most clients only care about 0 vs 'something nonzero' - the return value of wc_match, where -1 indicates a syntax error in the wildcard. - the return values from SSH-1 RSA-key loading functions, which use -1 for 'wrong passphrase' and 0 for all other failures (so any caller which already knows it's not loading an _encrypted private_ key can treat them as boolean) - term->esc_query, and the 'query' parameter in toggle_mode in terminal.c, which _usually_ hold 0 for ESC[123h or 1 for ESC[?123h, but can also hold -1 for some other intervening character that we don't support. In a few places there's an integer that I haven't turned into a bool even though it really _can_ only take values 0 or 1 (and, as above, tried to make the call sites consistent in not calling those values true and false), on the grounds that I thought it would make it more confusing to imply that the 0 value was in some sense 'negative' or bad and the 1 positive or good: - the return value of plug_accepting uses the POSIXish convention of 0=success and nonzero=error; I think if I made it bool then I'd also want to reverse its sense, and that's a job for a separate piece of work. - the 'screen' parameter to lineptr() in terminal.c, where 0 and 1 represent the default and alternate screens. There's no obvious reason why one of those should be considered 'true' or 'positive' or 'success' - they're just indices - so I've left it as int. ssh_scp_recv had particularly confusing semantics for its previous int return value: its call sites used '<= 0' to check for error, but it never actually returned a negative number, just 0 or 1. Now the function and its call sites agree that it's a bool. In a couple of places I've renamed variables called 'ret', because I don't like that name any more - it's unclear whether it means the return value (in preparation) for the _containing_ function or the return value received from a subroutine call, and occasionally I've accidentally used the same variable for both and introduced a bug. So where one of those got in my way, I've renamed it to 'toret' or 'retd' (the latter short for 'returned') in line with my usual modern practice, but I haven't done a thorough job of finding all of them. Finally, one amusing side effect of doing this is that I've had to separate quite a few chained assignments. It used to be perfectly fine to write 'a = b = c = TRUE' when a,b,c were int and TRUE was just a the 'true' defined by stdbool.h, that idiom provokes a warning from gcc: 'suggest parentheses around assignment used as truth value'!

Reorganise handling of WM_SIZE to fix two generality problems.

Windows: make the need_backend_resize mechanism consistent. There were three separate clauses in the WM_SIZE message handler which potentially called term_size() to resize the actual Terminal object. Two of them (for maximisation and normal non-maximised resizing drags) first checked if an interactive resize was in progress, and if so, instead set the need_backend_resize, to defer the term_size call to the end of the interactive operation. But the third, for _un_-maximising a window, didn't have that check. As a result, if you start with a maximised window, drag its title bar downward from the top of the screen (which unmaximises it), and without letting go, drag it back up again (which maximises it), the effect would be that you'd get one call to term_size in the middle of the drag, and a second at the end. This isn't what I intended, and it can also cause a redraw failure in full-screen applications on the server (such as a terminal-based text editor - I reproduced this with emacs), in which after the second term_size the terminal doesn't manage to redraw itself. Now I've pulled out the common logic that was in two of those three pieces of code (and should have been in all three) into a subroutine wm_size_resize_term, and arranged to call that in all three cases. This fixes the inconsistency, and also fixes the emacs redraw problem in the edge case I describe above.

The _intended_ visible effects of this change are that all arbitrary limits on configuration strings and lists (e.g. limit on number of port forwardings) should now disappear; that list boxes in the configuration will now be displayed in a sorted order rather than the arbitrary order in which they were added to the list (since the underlying data structure is now a sorted tree234 rather than an ad-hoc comma-separated string); and one more specific change, which is that local and dynamic port forwardings on the same port number are now mutually exclusive in the configuration (putting 'D' in the key rather than the value was a mistake in the first place).

Fix missing recalculation of window border. If you open a Windows PuTTY session and press Win+Right, Windows auto-sizes the terminal window to cover the right-hand half of the screen. Then if you press Win+Up it will be auto-sized again, this time to the top right quadrant. In the second resize (if you don't have font-based resize handling turned on), the WM_SIZE handler code will find a path through the twisty maze of ifs on which the border between the text and the client-area edges is not recomputed, or invalidated, or redrawn. So you can end up with half a line of text from the previous window size still visible at the bottom of the new window. Fixed by factoring out the offset-recomputation code from the large and complicated reset_window(), so that I can call just that snippet on the dangerous code path.

Formatting change to braces around one case of a switch. Sometimes, within a switch statement, you want to declare local variables specific to the handler for one particular case. Until now I've mostly been writing this in the form switch (discriminant) { case SIMPLE: do stuff; break; case COMPLICATED: { declare variables; do stuff; } break; } which is ugly because the two pieces of essentially similar code appear at different indent levels, and also inconvenient because you have less horizontal space available to write the complicated case handler in - particuarly undesirable because _complicated_ case handlers are the ones most likely to need all the space they can get! After encountering a rather nicer idiom in the LLVM source code, and after a bit of hackery this morning figuring out how to persuade Emacs's auto-indent to do what I wanted with it, I've decided to move to an idiom in which the open brace comes right after the case statement, and the code within it is indented the same as it would have been without the brace. Then the whole case handler (including the break) lives inside those braces, and you get something that looks more like this: switch (discriminant) { case SIMPLE: do stuff; break; case COMPLICATED: { declare variables; do stuff; break; } } This commit is a big-bang change that reformats all the complicated case handlers I could find into the new layout. This is particularly nice in the Pageant main function, in which almost _every_ case handler had a bundle of variables and was long and complicated. (In fact that's what motivated me to get round to this.) Some of the innermost parts of the terminal escape-sequence handling are also breathing a bit easier now the horizontal pressure on them is relieved. (Also, in a few cases, I was able to remove the extra braces completely, because the only variable local to the case handler was a loop variable which our new C99 policy allows me to move into the initialiser clause of its for statement.) Viewed with whitespace ignored, this is not too disruptive a change. Downstream patches that conflict with it may need to be reapplied using --ignore-whitespace or similar.

Formatting change to braces around one case of a switch. Sometimes, within a switch statement, you want to declare local variables specific to the handler for one particular case. Until now I've mostly been writing this in the form switch (discriminant) { case SIMPLE: do stuff; break; case COMPLICATED: { declare variables; do stuff; } break; } which is ugly because the two pieces of essentially similar code appear at different indent levels, and also inconvenient because you have less horizontal space available to write the complicated case handler in - particuarly undesirable because _complicated_ case handlers are the ones most likely to need all the space they can get! After encountering a rather nicer idiom in the LLVM source code, and after a bit of hackery this morning figuring out how to persuade Emacs's auto-indent to do what I wanted with it, I've decided to move to an idiom in which the open brace comes right after the case statement, and the code within it is indented the same as it would have been without the brace. Then the whole case handler (including the break) lives inside those braces, and you get something that looks more like this: switch (discriminant) { case SIMPLE: do stuff; break; case COMPLICATED: { declare variables; do stuff; break; } } This commit is a big-bang change that reformats all the complicated case handlers I could find into the new layout. This is particularly nice in the Pageant main function, in which almost _every_ case handler had a bundle of variables and was long and complicated. (In fact that's what motivated me to get round to this.) Some of the innermost parts of the terminal escape-sequence handling are also breathing a bit easier now the horizontal pressure on them is relieved. (Also, in a few cases, I was able to remove the extra braces completely, because the only variable local to the case handler was a loop variable which our new C99 policy allows me to move into the initialiser clause of its for statement.) Viewed with whitespace ignored, this is not too disruptive a change. Downstream patches that conflict with it may need to be reapplied using --ignore-whitespace or similar.

Refactor terminal input to remove ldiscucs.c. The functions that previously lived in it now live in terminal.c itself; they've been renamed term_keyinput and term_keyinputw, and their function is to add data to the terminal's user input buffer from a char or wchar_t string respectively. They sit more comfortably in terminal.c anyway, because their whole point is to translate into the character encoding that the terminal is currently configured to use. Also, making them part of the terminal code means they can also take care of calling term_seen_key_event(), which simplifies most of the call sites in the GTK and Windows front ends. Generation of text _inside_ terminal.c, from responses to query escape sequences, is therefore not done by calling those external entry points: we send those responses directly to the ldisc, so that they don't count as keypresses for all the user-facing purposes like bell overload handling and scrollback reset. To make _that_ convenient, I've arranged that most of the code that previously lived in lpage_send and luni_send is now in separate translation functions, so those can still be called from situations where you're not going to do the default thing with the translated data. (However, pasted data _does_ still count as close enough to a keypress to call term_seen_key_event - but it clears the 'interactive' flag when the data is passed on to the line discipline, which tweaks a minor detail of control-char handling in line ending mode but mostly just means pastes aren't interrupted.)

Centralise palette setup into terminal.c. Now terminal.c makes nearly all the decisions about what the colour palette should actually contain: it does the job of reading the GUI-configurable colours out of Conf, and also the job of making up the rest of the xterm-256 palette. The only exception is that TermWin can provide a method to override some of the default colours, which on Windows is used to implement the 'Use system colours' config option. This saves code overall, partly because the front ends don't have to be able to send palette data back to the Terminal any more (the Terminal keeps the master copy and can answer palette-query escape sequences from its own knowledge), and also because now there's only one copy of the xterm-256 palette setup code (previously gtkwin.c and window.c each had their own version of it). In this rewrite, I've also introduced a multi-layered storage system for the palette data in Terminal. One layer contains the palette information derived from Conf; the next contains platform overrides (currently just Windows's 'Use system colours'); the last one contains overrides set by escape sequences in the middle of the session. The topmost two layers can each _conditionally_ override the ones below. As a result, if a server-side application manually resets (say) the default fg and bg colours in mid-session to something that works well in a particular application, those changes won't be wiped out by a change in the Windows system colours or the Conf, which they would have been before. Instead, changes in Conf or the system colours alter the lower layers of the structure, but then when palette_rebuild is called, the upper layer continues to override them, until a palette reset (ESC]R) or terminal reset (e.g. ESC c) removes those upper-layer changes. This seems like a more consistent strategy, in that the same set of configuration settings will produce the same end result regardless of what order they were applied in. The palette-related methods in TermWin have had a total rework. palette_get and palette_reset are both gone; palette_set can now set a contiguous range of colours in one go; and the new palette_get_overrides replaces window.c's old systopalette().

Turn the Windows PuTTY main window into a Unicode window. This causes WM_CHAR messages sent to us to have a wParam containing a 16-bit value encoded in UTF-16, rather than an 8-bit value encoded in the system code page. As far as I can tell, there aren't many other knock-on effects - e.g. you can still interact with the window using ordinary char-based API functions such as SetWindowText, and the Windows API will do the necessary conversions behind the scenes. However, even so, I'm half expecting some sort of unforeseen bug to show up as a result of this.

Remove the 'Frontend' type and replace it with a vtable. After the recent Seat and LogContext revamps, _nearly_ all the remaining uses of the type 'Frontend' were in terminal.c, which needs all sorts of interactions with the GUI window the terminal lives in, from the obvious (actually drawing text on the window, reading and writing the clipboard) to the obscure (minimising, maximising and moving the window in response to particular escape sequences). All of those functions are now provided by an abstraction called TermWin. The few remaining uses of Frontend after _that_ are internal to a particular platform directory, so as to spread the implementation of that particular kind of Frontend between multiple source files; so I've renamed all of those so that they take a more specifically named type that refers to the particular implementation rather than the general abstraction. So now the name 'Frontend' no longer exists in the code base at all, and everywhere one used to be used, it's completely clear whether it was operating in one of Frontend's three abstract roles (and if so, which), or whether it was specific to a particular implementation. Another type that's disappeared is 'Context', which used to be a typedef defined to something different on each platform, describing whatever short-lived resources were necessary to draw on the terminal window: the front end would provide a ready-made one when calling term_paint, and the terminal could request one with get_ctx/free_ctx if it wanted to do proactive window updates. Now that drawing context lives inside the TermWin itself, because there was never any need to have two of those contexts live at the same time. (Another minor API change is that the window-title functions - both reading and writing - have had a missing 'const' added to their char * parameters / return values.) I don't expect this change to enable any particularly interesting new functionality (in particular, I have no plans that need more than one implementation of TermWin in the same application). But it completes the tidying-up that began with the Seat and LogContext rework.

/* we should have the IMM functions */
GUI PuTTY: stop using the global 'hwnd'. This was the difficult part of cleaning up that global variable. The main Windows PuTTY GUI is split between source files, so that _does_ actually need to refer to the main window from multiple places. But all the places where windlg.c needed to use 'hwnd' are seat methods, so they were already receiving a Seat pointer as a parameter. In other words, the methods of the Windows GUI Seat were already split between source files. So it seems only fair that they should be able to share knowledge of the seat's data as well. Hence, I've created a small 'WinGuiSeat' structure which both window.c and windlg.c can see the layout of, and put the main terminal window handle in there. Then the seat methods implemented in windlg.c, like win_seat_verify_ssh_host_key, can use container_of to turn the Seat pointer parameter back into the address of that structure, just as the methods in window.c can do (even though they currently don't need to). (Who knows: now that it _exists_, perhaps that structure can be gradually expanded in future to turn it into a proper encapsulation of all the Windows frontend's state, like we should have had all along...) I've also moved the Windows GUI LogPolicy implementation into the same object (i.e. WinGuiSeat implements both traits at once). That allows win_gui_logging_error to recover the same WinGuiSeat from its input LogPolicy pointer, which means it can get from there to the Seat facet of the same object, so that I don't need the extern variable 'win_seat' any more either.

Convert a lot of 'int' variables to 'bool'. My normal habit these days, in new code, is to treat int and bool as _almost_ completely separate types. I'm still willing to use C's implicit test for zero on an integer (e.g. 'if (!blob.len)' is fine, no need to spell it out as blob.len != 0), but generally, if a variable is going to be conceptually a boolean, I like to declare it bool and assign to it using 'true' or 'false' rather than 0 or 1. PuTTY is an exception, because it predates the C99 bool, and I've stuck to its existing coding style even when adding new code to it. But it's been annoying me more and more, so now that I've decided C99 bool is an acceptable thing to require from our toolchain in the first place, here's a quite thorough trawl through the source doing 'boolification'. Many variables and function parameters are now typed as bool rather than int; many assignments of 0 or 1 to those variables are now spelled 'true' or 'false'. I managed this thorough conversion with the help of a custom clang plugin that I wrote to trawl the AST and apply heuristics to point out where things might want changing. So I've even managed to do a decent job on parts of the code I haven't looked at in years! To make the plugin's work easier, I pushed platform front ends generally in the direction of using standard 'bool' in preference to platform-specific boolean types like Windows BOOL or GTK's gboolean; I've left the platform booleans in places they _have_ to be for the platform APIs to work right, but variables only used by my own code have been converted wherever I found them. In a few places there are int values that look very like booleans in _most_ of the places they're used, but have a rarely-used third value, or a distinction between different nonzero values that most users don't care about. In these cases, I've _removed_ uses of 'true' and 'false' for the return values, to emphasise that there's something more subtle going on than a simple boolean answer: - the 'multisel' field in dialog.h's list box structure, for which the GTK front end in particular recognises a difference between 1 and 2 but nearly everything else treats as boolean - the 'urgent' parameter to plug_receive, where 1 vs 2 tells you something about the specific location of the urgent pointer, but most clients only care about 0 vs 'something nonzero' - the return value of wc_match, where -1 indicates a syntax error in the wildcard. - the return values from SSH-1 RSA-key loading functions, which use -1 for 'wrong passphrase' and 0 for all other failures (so any caller which already knows it's not loading an _encrypted private_ key can treat them as boolean) - term->esc_query, and the 'query' parameter in toggle_mode in terminal.c, which _usually_ hold 0 for ESC[123h or 1 for ESC[?123h, but can also hold -1 for some other intervening character that we don't support. In a few places there's an integer that I haven't turned into a bool even though it really _can_ only take values 0 or 1 (and, as above, tried to make the call sites consistent in not calling those values true and false), on the grounds that I thought it would make it more confusing to imply that the 0 value was in some sense 'negative' or bad and the 1 positive or good: - the return value of plug_accepting uses the POSIXish convention of 0=success and nonzero=error; I think if I made it bool then I'd also want to reverse its sense, and that's a job for a separate piece of work. - the 'screen' parameter to lineptr() in terminal.c, where 0 and 1 represent the default and alternate screens. There's no obvious reason why one of those should be considered 'true' or 'positive' or 'success' - they're just indices - so I've left it as int. ssh_scp_recv had particularly confusing semantics for its previous int return value: its call sites used '<= 0' to check for error, but it never actually returned a negative number, just 0 or 1. Now the function and its call sites agree that it's a bool. In a couple of places I've renamed variables called 'ret', because I don't like that name any more - it's unclear whether it means the return value (in preparation) for the _containing_ function or the return value received from a subroutine call, and occasionally I've accidentally used the same variable for both and introduced a bug. So where one of those got in my way, I've renamed it to 'toret' or 'retd' (the latter short for 'returned') in line with my usual modern practice, but I haven't done a thorough job of finding all of them. Finally, one amusing side effect of doing this is that I've had to separate quite a few chained assignments. It used to be perfectly fine to write 'a = b = c = TRUE' when a,b,c were int and TRUE was just a the 'true' defined by stdbool.h, that idiom provokes a warning from gcc: 'suggest parentheses around assignment used as truth value'!

bool force_manual_underline = false;
Re-engineering of terminal emulator, phase 1. The active terminal screen is no longer an array of `unsigned long' encoding 16-bit Unicode plus 16 attribute bits. Now it's an array of `termchar' structures, which currently have 32-bit Unicode and 32 attribute bits but which will probably expand further in future. To prevent bloat of the memory footprint, I've introduced a mostly RLE-like compression scheme for storing scrollback: each line is compressed into a compact (but hard to modify) form when it moves into the term->scrollback tree, and is temporarily decompressed when the user wants to scroll back over it. My initial tests suggest that this compression averages about 1/4 of the previous (32 bits per character cell) data size in typical output, which means this is an improvement even without counting the new ability to extend the information stored in each character cell. Another beneficial side effect is that the insane format in which Unicode was passed to front ends through do_text() has now been rendered sane. Testing is incomplete; this _may_ still have instabilities. Windows and Unix front ends both seem to work as far as I've looked, but I haven't yet looked very hard. The Mac front end I've edited (it seemed obvious how to change it) but I can't compile or test it. As an immediate functional effect, the terminal emulator now supports full 32-bit Unicode to whatever extent the host platform allows it to. For example, if you output a 4-or-more-byte UTF-8 character in Unix pterm, it will not display it properly, but it will correctly paste it back out in a UTF8_STRING selection. Windows is more restricted, sadly. [originally from svn r4609]

Support for using variable-pitch fonts for the terminal on Windows. Done in much the same way as it is in the GTK front end: the character cell width is determined using the font's digits (which seems to give generally not-too-offensive spacing in most cases, at the expense of Ms and Ws typically overhanging a bit into adjacent cells) and each character is centred in its cell. Overhangs never leave permanent droppings on the window, because the existing work done in r5003 handles them just fine even in this stressful scenario. There's a hacky new checkbox in the Appearance panel to make variable-pitch fonts appear in the font selector (they still don't by default, because I still think it's _usually_ not What You Want); the checkbox state is not actually stored as part of a saved session, but it should be automatically ticked when reloading a session that's got a variable pitch font selected. (I'm half-expecting a potential flurry of requests for this feature in the wake of http://xkcd.com/840/ , so I thought I'd pre-empt them :-) [originally from svn r9063] [r5003 == ba470dec5e37ffbde05425f48e7e9a64219aec2e]

To make the plugin's work easier, I pushed platform front ends generally in the direction of using standard 'bool' in preference to platform-specific boolean types like Windows BOOL or GTK's gboolean; I've left the platform booleans in places they _have_ to be for the platform APIs to work right, but variables only used by my own code have been converted wherever I found them. In a few places there are int values that look very like booleans in _most_ of the places they're used, but have a rarely-used third value, or a distinction between different nonzero values that most users don't care about. In these cases, I've _removed_ uses of 'true' and 'false' for the return values, to emphasise that there's something more subtle going on than a simple boolean answer: - the 'multisel' field in dialog.h's list box structure, for which the GTK front end in particular recognises a difference between 1 and 2 but nearly everything else treats as boolean - the 'urgent' parameter to plug_receive, where 1 vs 2 tells you something about the specific location of the urgent pointer, but most clients only care about 0 vs 'something nonzero' - the return value of wc_match, where -1 indicates a syntax error in the wildcard. - the return values from SSH-1 RSA-key loading functions, which use -1 for 'wrong passphrase' and 0 for all other failures (so any caller which already knows it's not loading an _encrypted private_ key can treat them as boolean) - term->esc_query, and the 'query' parameter in toggle_mode in terminal.c, which _usually_ hold 0 for ESC[123h or 1 for ESC[?123h, but can also hold -1 for some other intervening character that we don't support. In a few places there's an integer that I haven't turned into a bool even though it really _can_ only take values 0 or 1 (and, as above, tried to make the call sites consistent in not calling those values true and false), on the grounds that I thought it would make it more confusing to imply that the 0 value was in some sense 'negative' or bad and the 1 positive or good: - the return value of plug_accepting uses the POSIXish convention of 0=success and nonzero=error; I think if I made it bool then I'd also want to reverse its sense, and that's a job for a separate piece of work. - the 'screen' parameter to lineptr() in terminal.c, where 0 and 1 represent the default and alternate screens. There's no obvious reason why one of those should be considered 'true' or 'positive' or 'success' - they're just indices - so I've left it as int. ssh_scp_recv had particularly confusing semantics for its previous int return value: its call sites used '<= 0' to check for error, but it never actually returned a negative number, just 0 or 1. Now the function and its call sites agree that it's a bool. In a couple of places I've renamed variables called 'ret', because I don't like that name any more - it's unclear whether it means the return value (in preparation) for the _containing_ function or the return value received from a subroutine call, and occasionally I've accidentally used the same variable for both and introduced a bug. So where one of those got in my way, I've renamed it to 'toret' or 'retd' (the latter short for 'returned') in line with my usual modern practice, but I haven't done a thorough job of finding all of them. Finally, one amusing side effect of doing this is that I've had to separate quite a few chained assignments. It used to be perfectly fine to write 'a = b = c = TRUE' when a,b,c were int and TRUE was just a the 'true' defined by stdbool.h, that idiom provokes a warning from gcc: 'suggest parentheses around assignment used as truth value'!

Rationalise the mechanism in do_text_internal for providing the 'lpDx' array to ExtTextOut: - move it inside the new big loop (this should fix a potential bug whereby the DBCS handling altered some elements of it but the loop did not actually step along it) - initialise it more sensibly - rename it to lpDx rather than IpDx, since as far as I can tell the latter name was derived from a misreading of the former in the Windows API docs.

New array-growing macros: sgrowarray and sgrowarrayn. The idea of these is that they centralise the common idiom along the lines of if (logical_array_len >= physical_array_size) { physical_array_size = logical_array_len * 5 / 4 + 256; array = sresize(array, physical_array_size, ElementType); } which happens at a zillion call sites throughout this code base, with different random choices of the geometric factor and additive constant, sometimes forgetting them completely, and generally doing a lot of repeated work. The new macro sgrowarray(array,size,n) has the semantics: here are the array pointer and its physical size for you to modify, now please ensure that the nth element exists, so I can write into it. And sgrowarrayn(array,size,n,m) is the same except that it ensures that the array has size at least n+m (so sgrowarray is just the special case where m=1). Now that this is a single centralised implementation that will be used everywhere, I've also gone to more effort in the implementation, with careful overflow checks that would have been painful to put at all the previous call sites. This commit also switches over every use of sresize(), apart from a few where I really didn't think it would gain anything. A consequence of that is that a lot of array-size variables have to have their types changed to size_t, because the macros require that (they address-take the size to pass to the underlying function).

Patch from Yoshida Masato to fill in the missing pieces of Windows UTF-16 support. High Unicode characters in the terminal are now converted back into surrogates during copy and draw operations, and the Windows drawing code takes account of that when splitting up the UTF-16 string for display. Meanwhile, accidental uses of wchar_t have been replaced with 32-bit integers in parts of the cross-platform code which were expecting not to have to deal with UTF-16. [originally from svn r9409]

Re-engineering of terminal emulator, phase 1. The active terminal screen is no longer an array of `unsigned long' encoding 16-bit Unicode plus 16 attribute bits. Now it's an array of `termchar' structures, which currently have 32-bit Unicode and 32 attribute bits but which will probably expand further in future. To prevent bloat of the memory footprint, I've introduced a mostly RLE-like compression scheme for storing scrollback: each line is compressed into a compact (but hard to modify) form when it moves into the term->scrollback tree, and is temporarily decompressed when the user wants to scroll back over it. My initial tests suggest that this compression averages about 1/4 of the previous (32 bits per character cell) data size in typical output, which means this is an improvement even without counting the new ability to extend the information stored in each character cell. Another beneficial side effect is that the insane format in which Unicode was passed to front ends through do_text() has now been rendered sane. Testing is incomplete; this _may_ still have instabilities. Windows and Unix front ends both seem to work as far as I've looked, but I haven't yet looked very hard. The Mac front end I've edited (it seemed obvious how to change it) but I can't compile or test it. As an immediate functional effect, the terminal emulator now supports full 32-bit Unicode to whatever extent the host platform allows it to. For example, if you output a 4-or-more-byte UTF-8 character in Unix pterm, it will not display it properly, but it will correctly paste it back out in a UTF8_STRING selection. Windows is more restricted, sadly. [originally from svn r4609]

Major destabilisation, phase 1. In this phase I've moved (I think) all the global and function-static variables out of terminal.c into a dynamically allocated data structure. Note that this does not yet confer the ability to run more than one of them in the same process, because other things (the line discipline, the back end) are still global, and also in particular the address of the dynamically allocated terminal-data structure is held in a global variable `term'. But what I've got here represents a reasonable stopping point at which to check things in. In _theory_ this should all still work happily, on both Unix and Windows. In practice, who knows?

Post-release destabilisation! Completely remove the struct type 'Config' in putty.h, which stores all PuTTY's settings and includes an arbitrary length limit on every single one of those settings which is stored in string form. In place of it is 'Conf', an opaque data type everywhere outside the new file conf.c, which stores a list of (key, value) pairs in which every key contains an integer identifying a configuration setting, and for some of those integers the key also contains extra parts (so that, for instance, CONF_environmt is a string-to-string mapping). Everywhere that a Config was previously used, a Conf is now; everywhere there was a Config structure copy, conf_copy() is called; every lookup, adjustment, load and save operation on a Config has been rewritten; and there's a mechanism for serialising a Conf into a binary blob and back for use with Duplicate Session. User-visible effects of this change _should_ be minimal, though I don't doubt I've introduced one or two bugs here and there which will eventually be found. The _intended_ visible effects of this change are that all arbitrary limits on configuration strings and lists (e.g. limit on number of port forwardings) should now disappear; that list boxes in the configuration will now be displayed in a sorted order rather than the arbitrary order in which they were added to the list (since the underlying data structure is now a sorted tree234 rather than an ad-hoc comma-separated string); and one more specific change, which is that local and dynamic port forwardings on the same port number are now mutually exclusive in the configuration (putting 'D' in the key rather than the value was a mistake in the first place). One other reorganisation as a result of this is that I've moved all the dialog.c standard handlers (dlg_stdeditbox_handler and friends) out into config.c, because I can't really justify calling them generic any more. When they took a pointer to an arbitrary structure type and the offset of a field within that structure, they were independent of whether that structure was a Config or something completely different, but now they really do expect to talk to a Conf, which can _only_ be used for PuTTY configuration, so I've renamed them all things like conf_editbox_handler and moved them out of the nominally independent dialog-box management module into the PuTTY-specific config.c.

RDB's Unicode patch. Fonts are now used in Unicode mode where possible and we have a single unified means of trying to display any Unicode code point. Instead of the various ad-hoc translation modes we had before, we now have a single `codepage' option which allows us to treat the incoming (and outgoing) text as any given character set, and locally we map that to Unicode and back.

Patch from Yoshida Masato to fill in the missing pieces of Windows UTF-16 support. High Unicode characters in the terminal are now converted back into surrogates during copy and draw operations, and the Windows drawing code takes account of that when splitting up the UTF-16 string for display. Meanwhile, accidental uses of wchar_t have been replaced with 32-bit integers in parts of the cross-platform code which were expecting not to have to deal with UTF-16. [originally from svn r9409]

Re-engineering of terminal emulator, phase 1. The active terminal screen is no longer an array of `unsigned long' encoding 16-bit Unicode plus 16 attribute bits. Now it's an array of `termchar' structures, which currently have 32-bit Unicode and 32 attribute bits but which will probably expand further in future. To prevent bloat of the memory footprint, I've introduced a mostly RLE-like compression scheme for storing scrollback: each line is compressed into a compact (but hard to modify) form when it moves into the term->scrollback tree, and is temporarily decompressed when the user wants to scroll back over it. My initial tests suggest that this compression averages about 1/4 of the previous (32 bits per character cell) data size in typical output, which means this is an improvement even without counting the new ability to extend the information stored in each character cell. Another beneficial side effect is that the insane format in which Unicode was passed to front ends through do_text() has now been rendered sane. Testing is incomplete; this _may_ still have instabilities. Windows and Unix front ends both seem to work as far as I've looked, but I haven't yet looked very hard. The Mac front end I've edited (it seemed obvious how to change it) but I can't compile or test it. As an immediate functional effect, the terminal emulator now supports full 32-bit Unicode to whatever extent the host platform allows it to. For example, if you output a 4-or-more-byte UTF-8 character in Unix pterm, it will not display it properly, but it will correctly paste it back out in a UTF8_STRING selection. Windows is more restricted, sadly. [originally from svn r4609]

xterm apparently supports ESC[90m through ESC[97m to set bright foreground colours, and ESC[100m through ESC[107m to set bright background colours. Hence, so do we. Bright-foreground is distinguishable from bold, and bright-background distinguishable from blink, when it leaves terminal.c; the front end may then choose to display them in the same way if it's configured to do so. This change makes the xterm backend for Turbo Vision (!!!) work properly. Untested on Mac. [originally from svn r2734]

Remove the 'Frontend' type and replace it with a vtable. After the recent Seat and LogContext revamps, _nearly_ all the remaining uses of the type 'Frontend' were in terminal.c, which needs all sorts of interactions with the GUI window the terminal lives in, from the obvious (actually drawing text on the window, reading and writing the clipboard) to the obscure (minimising, maximising and moving the window in response to particular escape sequences). All of those functions are now provided by an abstraction called TermWin. The few remaining uses of Frontend after _that_ are internal to a particular platform directory, so as to spread the implementation of that particular kind of Frontend between multiple source files; so I've renamed all of those so that they take a more specifically named type that refers to the particular implementation rather than the general abstraction. So now the name 'Frontend' no longer exists in the code base at all, and everywhere one used to be used, it's completely clear whether it was operating in one of Frontend's three abstract roles (and if so, which), or whether it was specific to a particular implementation. Another type that's disappeared is 'Context', which used to be a typedef defined to something different on each platform, describing whatever short-lived resources were necessary to draw on the terminal window: the front end would provide a ready-made one when calling term_paint, and the terminal could request one with get_ctx/free_ctx if it wanted to do proactive window updates. Now that drawing context lives inside the TermWin itself, because there was never any need to have two of those contexts live at the same time. (Another minor API change is that the window-title functions - both reading and writing - have had a missing 'const' added to their char * parameters / return values.) I don't expect this change to enable any particularly interesting new functionality (in particular, I have no plans that need more than one implementation of TermWin in the same application). But it completes the tidying-up that began with the Seat and LogContext rework.

First-stage support for Unicode combining characters. The `chars' array of each `termline' structure now contains optional additional entries after the normal number of columns, which are used to chain a linked list of combining characters off any primary termchar that needs it. This means we support arbitrarily many combining characters per cell (unlike xterm's hard limit of 2). Cut and paste works correctly (selecting a character cell containing multiple code points causes all those code points to be cut and pasted). Display works by simply overlaying all the relevant characters on top of one another; this is good enough for Unix (xterm does the same thing), and mostly seems OK for Windows except that the Windows Unicode fonts have a nasty habit of not containing most of the combining characters and thus overlaying an unknown-code-point box on your perfectly good base glyph. I had no idea how to add support in the Mac do_text(), so I've simply stuck in an assertion that will trigger the first time a combining character is displayed, and hopefully this will bite someone with the clue to fix it.

Whitespace rationalisation of entire code base. The number of people has been steadily increasing who read our source code with an editor that thinks tab stops are 4 spaces apart, as opposed to the traditional tty-derived 8 that the PuTTY code expects. So I've been wondering for ages about just fixing it, and switching to a spaces-only policy throughout the code. And I recently found out about 'git blame -w', which should make this change not too disruptive for the purposes of source-control archaeology; so perhaps now is the time. While I'm at it, I've also taken the opportunity to remove all the trailing spaces from source lines (on the basis that git dislikes them, and is the only thing that seems to have a strong opinion one way or the other). Apologies to anyone downstream of this code who has complicated patch sets to rebase past this change. I don't intend it to be needed again.

Major destabilisation, phase 1. In this phase I've moved (I think) all the global and function-static variables out of terminal.c into a dynamically allocated data structure. Note that this does not yet confer the ability to run more than one of them in the same process, because other things (the line discipline, the back end) are still global, and also in particular the address of the dynamically allocated terminal-data structure is held in a global variable `term'. But what I've got here represents a reasonable stopping point at which to check things in. In _theory_ this should all still work happily, on both Unix and Windows. In practice, who knows?

Support for using variable-pitch fonts for the terminal on Windows. Done in much the same way as it is in the GTK front end: the character cell width is determined using the font's digits (which seems to give generally not-too-offensive spacing in most cases, at the expense of Ms and Ws typically overhanging a bit into adjacent cells) and each character is centred in its cell. Overhangs never leave permanent droppings on the window, because the existing work done in r5003 handles them just fine even in this stressful scenario. There's a hacky new checkbox in the Appearance panel to make variable-pitch fonts appear in the font selector (they still don't by default, because I still think it's _usually_ not What You Want); the checkbox state is not actually stored as part of a saved session, but it should be automatically ticked when reloading a session that's got a variable pitch font selected.

Whitespace rationalisation of entire code base. The number of people has been steadily increasing who read our source code with an editor that thinks tab stops are 4 spaces apart, as opposed to the traditional tty-derived 8 that the PuTTY code expects. So I've been wondering for ages about just fixing it, and switching to a spaces-only policy throughout the code. And I recently found out about 'git blame -w', which should make this change not too disruptive for the purposes of source-control archaeology; so perhaps now is the time. While I'm at it, I've also taken the opportunity to remove all the trailing spaces from source lines (on the basis that git dislikes them, and is the only thing that seems to have a strong opinion one way or the other). Apologies to anyone downstream of this code who has complicated patch sets to rebase past this change. I don't intend it to be needed again.

if (len > lpDx_len) {
New array-growing macros: sgrowarray and sgrowarrayn. The idea of these is that they centralise the common idiom along the lines of if (logical_array_len >= physical_array_size) { physical_array_size = logical_array_len * 5 / 4 + 256; array = sresize(array, physical_array_size, ElementType); } which happens at a zillion call sites throughout this code base, with different random choices of the geometric factor and additive constant, sometimes forgetting them completely, and generally doing a lot of repeated work. The new macro sgrowarray(array,size,n) has the semantics: here are the array pointer and its physical size for you to modify, now please ensure that the nth element exists, so I can write into it. And sgrowarrayn(array,size,n,m) is the same except that it ensures that the array has size at least n+m (so sgrowarray is just the special case where m=1). Now that this is a single centralised implementation that will be used everywhere, I've also gone to more effort in the implementation, with careful overflow checks that would have been painful to put at all the previous call sites. This commit also switches over every use of sresize(), apart from a few where I really didn't think it would gain anything. A consequence of that is that a lot of array-size variables have to have their types changed to size_t, because the macros require that (they address-take the size to pass to the underlying function).

Re-engineering of terminal emulator, phase 1. The active terminal screen is no longer an array of `unsigned long' encoding 16-bit Unicode plus 16 attribute bits. Now it's an array of `termchar' structures, which currently have 32-bit Unicode and 32 attribute bits but which will probably expand further in future. To prevent bloat of the memory footprint, I've introduced a mostly RLE-like compression scheme for storing scrollback: each line is compressed into a compact (but hard to modify) form when it moves into the term->scrollback tree, and is temporarily decompressed when the user wants to scroll back over it. My initial tests suggest that this compression averages about 1/4 of the previous (32 bits per character cell) data size in typical output, which means this is an improvement even without counting the new ability to extend the information stored in each character cell. Another beneficial side effect is that the insane format in which Unicode was passed to front ends through do_text() has now been rendered sane. Testing is incomplete; this _may_ still have instabilities. Windows and Unix front ends both seem to work as far as I've looked, but I haven't yet looked very hard. The Mac front end I've edited (it seemed obvious how to change it) but I can't compile or test it. As an immediate functional effect, the terminal emulator now supports full 32-bit Unicode to whatever extent the host platform allows it to. For example, if you output a 4-or-more-byte UTF-8 character in Unix pterm, it will not display it properly, but it will correctly paste it back out in a UTF8_STRING selection. Windows is more restricted, sadly. [originally from svn r4609]

Remove the 'Frontend' type and replace it with a vtable. After the recent Seat and LogContext revamps, _nearly_ all the remaining uses of the type 'Frontend' were in terminal.c, which needs all sorts of interactions with the GUI window the terminal lives in, from the obvious (actually drawing text on the window, reading and writing the clipboard) to the obscure (minimising, maximising and moving the window in response to particular escape sequences). All of those functions are now provided by an abstraction called TermWin. The few remaining uses of Frontend after _that_ are internal to a particular platform directory, so as to spread the implementation of that particular kind of Frontend between multiple source files; so I've renamed all of those so that they take a more specifically named type that refers to the particular implementation rather than the general abstraction. So now the name 'Frontend' no longer exists in the code base at all, and everywhere one used to be used, it's completely clear whether it was operating in one of Frontend's three abstract roles (and if so, which), or whether it was specific to a particular implementation. Another type that's disappeared is 'Context', which used to be a typedef defined to something different on each platform, describing whatever short-lived resources were necessary to draw on the terminal window: the front end would provide a ready-made one when calling term_paint, and the terminal could request one with get_ctx/free_ctx if it wanted to do proactive window updates. Now that drawing context lives inside the TermWin itself, because there was never any need to have two of those contexts live at the same time. (Another minor API change is that the window-title functions - both reading and writing - have had a missing 'const' added to their char * parameters / return values.) I don't expect this change to enable any particularly interesting new functionality (in particular, I have no plans that need more than one implementation of TermWin in the same application). But it completes the tidying-up that began with the Seat and LogContext rework.

New array-growing macros: sgrowarray and sgrowarrayn. The idea of these is that they centralise the common idiom along the lines of if (logical_array_len >= physical_array_size) { physical_array_size = logical_array_len * 5 / 4 + 256; array = sresize(array, physical_array_size, ElementType); } which happens at a zillion call sites throughout this code base, with different random choices of the geometric factor and additive constant, sometimes forgetting them completely, and generally doing a lot of repeated work. The new macro sgrowarray(array,size,n) has the semantics: here are the array pointer and its physical size for you to modify, now please ensure that the nth element exists, so I can write into it. And sgrowarrayn(array,size,n,m) is the same except that it ensures that the array has size at least n+m (so sgrowarray is just the special case where m=1). Now that this is a single centralised implementation that will be used everywhere, I've also gone to more effort in the implementation, with careful overflow checks that would have been painful to put at all the previous call sites. This commit also switches over every use of sresize(), apart from a few where I really didn't think it would gain anything. A consequence of that is that a lot of array-size variables have to have their types changed to size_t, because the macros require that (they address-take the size to pass to the underlying function).

RDB's Unicode patch. Fonts are now used in Unicode mode where possible and we have a single unified means of trying to display any Unicode code point. Instead of the various ad-hoc translation modes we had before, we now have a single `codepage' option which allows us to treat the incoming (and outgoing) text as any given character set, and locally we map that to Unicode and back.

Remove the 'Frontend' type and replace it with a vtable. After the recent Seat and LogContext revamps, _nearly_ all the remaining uses of the type 'Frontend' were in terminal.c, which needs all sorts of interactions with the GUI window the terminal lives in, from the obvious (actually drawing text on the window, reading and writing the clipboard) to the obscure (minimising, maximising and moving the window in response to particular escape sequences). All of those functions are now provided by an abstraction called TermWin. The few remaining uses of Frontend after _that_ are internal to a particular platform directory, so as to spread the implementation of that particular kind of Frontend between multiple source files; so I've renamed all of those so that they take a more specifically named type that refers to the particular implementation rather than the general abstraction. So now the name 'Frontend' no longer exists in the code base at all, and everywhere one used to be used, it's completely clear whether it was operating in one of Frontend's three abstract roles (and if so, which), or whether it was specific to a particular implementation. Another type that's disappeared is 'Context', which used to be a typedef defined to something different on each platform, describing whatever short-lived resources were necessary to draw on the terminal window: the front end would provide a ready-made one when calling term_paint, and the terminal could request one with get_ctx/free_ctx if it wanted to do proactive window updates. Now that drawing context lives inside the TermWin itself, because there was never any need to have two of those contexts live at the same time. (Another minor API change is that the window-title functions - both reading and writing - have had a missing 'const' added to their char * parameters / return values.) I don't expect this change to enable any particularly interesting new functionality (in particular, I have no plans that need more than one implementation of TermWin in the same application).

Whitespace rationalisation of entire code base. The number of people has been steadily increasing who read our source code with an editor that thinks tab stops are 4 spaces apart, as opposed to the traditional tty-derived 8 that the PuTTY code expects. So I've been wondering for ages about just fixing it, and switching to a spaces-only policy throughout the code. And I recently found out about 'git blame -w', which should make this change not too disruptive for the purposes of source-control archaeology; so perhaps now is the time. While I'm at it, I've also taken the opportunity to remove all the trailing spaces from source lines (on the basis that git dislikes them, and is the only thing that seems to have a strong opinion one way or the other). Apologies to anyone downstream of this code who has complicated patch sets to rebase past this change. I don't intend it to be needed again.

First-stage support for Unicode combining characters. The `chars' array of each `termline' structure now contains optional additional entries after the normal number of columns, which are used to chain a linked list of combining characters off any primary termchar that needs it. This means we support arbitrarily many combining characters per cell (unlike xterm's hard limit of 2). Cut and paste works correctly (selecting a character cell containing multiple code points causes all those code points to be cut and pasted). Display works by simply overlaying all the relevant characters on top of one another; this is good enough for Unix (xterm does the same thing), and mostly seems OK for Windows except that the Windows Unicode fonts have a nasty habit of not containing most of the combining characters and thus overlaying an unknown-code-point box on your perfectly good base glyph. I had no idea how to add support in the Mac do_text(), so I've simply stuck in an assertion that will trigger the first time a combining character is displayed, and hopefully this will bite someone with the clue to fix it.

Done in much the same way as it is in the GTK front end: the character cell width is determined using the font's digits (which seems to give generally not-too-offensive spacing in most cases, at the expense of Ms and Ws typically overhanging a bit into adjacent cells) and each character is centred in its cell. Overhangs never leave permanent droppings on the window, because the existing work done in r5003 handles them just fine even in this stressful scenario. There's a hacky new checkbox in the Appearance panel to make variable-pitch fonts appear in the font selector (they still don't by default, because I still think it's _usually_ not What You Want); the checkbox state is not actually stored as part of a saved session, but it should be automatically ticked when reloading a session that's got a variable pitch font selected. (I'm half-expecting a potential flurry of requests for this feature in the wake of http://xkcd.com/840/ , so I thought I'd pre-empt them :-) [originally from svn r9063] [r5003 == ba470dec5e37ffbde05425f48e7e9a64219aec2e]

Rationalise the mechanism in do_text_internal for providing the 'lpDx' array to ExtTextOut: - move it inside the new big loop (this should fix a potential bug whereby the DBCS handling altered some elements of it but the loop did not actually step along it) - initialise it more sensibly - rename it to lpDx rather than IpDx, since as far as I can tell the latter name was derived from a misreading of the former in the Windows API docs.

First-stage support for Unicode combining characters. The `chars' array of each `termline' structure now contains optional additional entries after the normal number of columns, which are used to chain a linked list of combining characters off any primary termchar that needs it. This means we support arbitrarily many combining characters per cell (unlike xterm's hard limit of 2). Cut and paste works correctly (selecting a character cell containing multiple code points causes all those code points to be cut and pasted). Display works by simply overlaying all the relevant characters on top of one another; this is good enough for Unix (xterm does the same thing), and mostly seems OK for Windows except that the Windows Unicode fonts have a nasty habit of not containing most of the combining characters and thus overlaying an unknown-code-point box on your perfectly good base glyph. I had no idea how to add support in the Mac do_text(), so I've simply stuck in an assertion that will trigger the first time a combining character is displayed, and hopefully this will bite someone with the clue to fix it.

Remove the 'Frontend' type and replace it with a vtable. After the recent Seat and LogContext revamps, _nearly_ all the remaining uses of the type 'Frontend' were in terminal.c, which needs all sorts of interactions with the GUI window the terminal lives in, from the obvious (actually drawing text on the window, reading and writing the clipboard) to the obscure (minimising, maximising and moving the window in response to particular escape sequences). All of those functions are now provided by an abstraction called TermWin. The few remaining uses of Frontend after _that_ are internal to a particular platform directory, so as to spread the implementation of that particular kind of Frontend between multiple source files; so I've renamed all of those so that they take a more specifically named type that refers to the particular implementation rather than the general abstraction. So now the name 'Frontend' no longer exists in the code base at all, and everywhere one used to be used, it's completely clear whether it was operating in one of Frontend's three abstract roles (and if so, which), or whether it was specific to a particular implementation. Another type that's disappeared is 'Context', which used to be a typedef defined to something different on each platform, describing whatever short-lived resources were necessary to draw on the terminal window: the front end would provide a ready-made one when calling term_paint, and the terminal could request one with get_ctx/free_ctx if it wanted to do proactive window updates. Now that drawing context lives inside the TermWin itself, because there was never any need to have two of those contexts live at the same time. (Another minor API change is that the window-title functions - both reading and writing - have had a missing 'const' added to their char * parameters / return values.) I don't expect this change to enable any particularly interesting new functionality (in particular, I have no plans that need more than one implementation of TermWin in the same application). But it completes the tidying-up that began with the Seat and LogContext rework.

Adopt C99 <stdbool.h>'s true/false. This commit includes <stdbool.h> from defs.h and deletes my traditional definitions of TRUE and FALSE, but other than that, it's a 100% mechanical search-and-replace transforming all uses of TRUE and FALSE into the C99-standardised lowercase spellings. No actual types are changed in this commit; that will come next. This is just getting the noise out of the way, so that subsequent commits can have a higher proportion of signal.

Support SGR 9 for strikethrough effect on text. This is mostly easy: it's just like drawing an underline, except that you put it at a different height in the character cell. The only question is _where_ in the character cell. Pango, and Windows GetOutlineTextMetrics, will tell you exactly where the font wants to have it.

Everywhere that a Config was previously used, a Conf is now; everywhere there was a Config structure copy, conf_copy() is called; every lookup, adjustment, load and save operation on a Config has been rewritten; and there's a mechanism for serialising a Conf into a binary blob and back for use with Duplicate Session. User-visible effects of this change _should_ be minimal, though I don't doubt I've introduced one or two bugs here and there which will eventually be found. The _intended_ visible effects of this change are that all arbitrary limits on configuration strings and lists (e.g. limit on number of port forwardings) should now disappear; that list boxes in the configuration will now be displayed in a sorted order rather than the arbitrary order in which they were added to the list (since the underlying data structure is now a sorted tree234 rather than an ad-hoc comma-separated string); and one more specific change, which is that local and dynamic port forwardings on the same port number are now mutually exclusive in the configuration (putting 'D' in the key rather than the value was a mistake in the first place). One other reorganisation as a result of this is that I've moved all the dialog.c standard handlers (dlg_stdeditbox_handler and friends) out into config.c, because I can't really justify calling them generic any more. When they took a pointer to an arbitrary structure type and the offset of a field within that structure, they were independent of whether that structure was a Config or something completely different, but now they really do expect to talk to a Conf, which can _only_ be used for PuTTY configuration, so I've renamed them all things like conf_editbox_handler and moved them out of the nominally independent dialog-box management module into the PuTTY-specific config.c.

Add a TermWin method to draw a 'trust sigil'. This is not yet used by anything, but the idea is that it'll be a graphic in the terminal window that can't be replicated by a server sending escape sequences, and hence can be used as a reliable indication that the text on a particular terminal line is generated by PuTTY itself and not passed through from the server. This will make it possible to detect a malicious server trying to mimic local prompts to trick you out of information that shouldn't be sent over the wire (such as private-key passphrases). The trust sigil I've picked is a small copy of the PuTTY icon, which is thematically nice (it can be read as if the PuTTY icon is the name of the speaker in a dialogue) and also convenient because we had that graphic available already on all platforms. (Though the contortions I had to go through to make the GTK 1 code draw it were quite annoying.) The trust sigil has the same dimensions as a CJK double-width character, i.e. it's 2 character cells wide by 1 high.

Remove the 'Frontend' type and replace it with a vtable. After the recent Seat and LogContext revamps, _nearly_ all the remaining uses of the type 'Frontend' were in terminal.c, which needs all sorts of interactions with the GUI window the terminal lives in, from the obvious (actually drawing text on the window, reading and writing the clipboard) to the obscure (minimising, maximising and moving the window in response to particular escape sequences). All of those functions are now provided by an abstraction called TermWin. The few remaining uses of Frontend after _that_ are internal to a particular platform directory, so as to spread the implementation of that particular kind of Frontend between multiple source files; so I've renamed all of those so that they take a more specifically named type that refers to the particular implementation rather than the general abstraction. So now the name 'Frontend' no longer exists in the code base at all, and everywhere one used to be used, it's completely clear whether it was operating in one of Frontend's three abstract roles (and if so, which), or whether it was specific to a particular implementation. Another type that's disappeared is 'Context', which used to be a typedef defined to something different on each platform, describing whatever short-lived resources were necessary to draw on the terminal window: the front end would provide a ready-made one when calling term_paint, and the terminal could request one with get_ctx/free_ctx if it wanted to do proactive window updates. Now that drawing context lives inside the TermWin itself, because there was never any need to have two of those contexts live at the same time. (Another minor API change is that the window-title functions - both reading and writing - have had a missing 'const' added to their char * parameters / return values.) I don't expect this change to enable any particularly interesting new functionality (in particular, I have no plans that need more than one implementation of TermWin in the same application). But it completes the tidying-up that began with the Seat and LogContext rework.

Re-engineering of terminal emulator, phase 1. The active terminal screen is no longer an array of `unsigned long' encoding 16-bit Unicode plus 16 attribute bits. Now it's an array of `termchar' structures, which currently have 32-bit Unicode and 32 attribute bits but which will probably expand further in future. To prevent bloat of the memory footprint, I've introduced a mostly RLE-like compression scheme for storing scrollback: each line is compressed into a compact (but hard to modify) form when it moves into the term->scrollback tree, and is temporarily decompressed when the user wants to scroll back over it. My initial tests suggest that this compression averages about 1/4 of the previous (32 bits per character cell) data size in typical output, which means this is an improvement even without counting the new ability to extend the information stored in each character cell. Another beneficial side effect is that the insane format in which Unicode was passed to front ends through do_text() has now been rendered sane. Testing is incomplete; this _may_ still have instabilities. Windows and Unix front ends both seem to work as far as I've looked, but I haven't yet looked very hard. The Mac front end I've edited (it seemed obvious how to change it) but I can't compile or test it. As an immediate functional effect, the terminal emulator now supports full 32-bit Unicode to whatever extent the host platform allows it to. For example, if you output a 4-or-more-byte UTF-8 character in Unix pterm, it will not display it properly, but it will correctly paste it back out in a UTF8_STRING selection.

BYTE keystate[256];
Convert a lot of 'int' variables to 'bool'. My normal habit these days, in new code, is to treat int and bool as _almost_ completely separate types. I'm still willing to use C's implicit test for zero on an integer (e.g. 'if (!blob.len)' is fine, no need to spell it out as blob.len != 0), but generally, if a variable is going to be conceptually a boolean, I like to declare it bool and assign to it using 'true' or 'false' rather than 0 or 1. PuTTY is an exception, because it predates the C99 bool, and I've stuck to its existing coding style even when adding new code to it. But it's been annoying me more and more, so now that I've decided C99 bool is an acceptable thing to require from our toolchain in the first place, here's a quite thorough trawl through the source doing 'boolification'. Many variables and function parameters are now typed as bool rather than int; many assignments of 0 or 1 to those variables are now spelled 'true' or 'false'. I managed this thorough conversion with the help of a custom clang plugin that I wrote to trawl the AST and apply heuristics to point out where things might want changing. So I've even managed to do a decent job on parts of the code I haven't looked at in years! To make the plugin's work easier, I pushed platform front ends generally in the direction of using standard 'bool' in preference to platform-specific boolean types like Windows BOOL or GTK's gboolean; I've left the platform booleans in places they _have_ to be for the platform APIs to work right, but variables only used by my own code have been converted wherever I found them. In a few places there are int values that look very like booleans in _most_ of the places they're used, but have a rarely-used third value, or a distinction between different nonzero values that most users don't care about. In these cases, I've _removed_ uses of 'true' and 'false' for the return values, to emphasise that there's something more subtle going on than a simple boolean answer: - the 'multisel' field in dialog.h's list box structure, for which the GTK front end in particular recognises a difference between 1 and 2 but nearly everything else treats as boolean - the 'urgent' parameter to plug_receive, where 1 vs 2 tells you something about the specific location of the urgent pointer, but most clients only care about 0 vs 'something nonzero' - the return value of wc_match, where -1 indicates a syntax error in the wildcard. - the return values from SSH-1 RSA-key loading functions, which use -1 for 'wrong passphrase' and 0 for all other failures (so any caller which already knows it's not loading an _encrypted private_ key can treat them as boolean) - term->esc_query, and the 'query' parameter in toggle_mode in terminal.c, which _usually_ hold 0 for ESC[123h or 1 for ESC[?123h, but can also hold -1 for some other intervening character that we don't support. In a few places there's an integer that I haven't turned into a bool even though it really _can_ only take values 0 or 1 (and, as above, tried to make the call sites consistent in not calling those values true and false), on the grounds that I thought it would make it more confusing to imply that the 0 value was in some sense 'negative' or bad and the 1 positive or good: - the return value of plug_accepting uses the POSIXish convention of 0=success and nonzero=error; I think if I made it bool then I'd also want to reverse its sense, and that's a job for a separate piece of work. - the 'screen' parameter to lineptr() in terminal.c, where 0 and 1 represent the default and alternate screens. There's no obvious reason why one of those should be considered 'true' or 'positive' or 'success' - they're just indices - so I've left it as int. ssh_scp_recv had particularly confusing semantics for its previous int return value: its call sites used '<= 0' to check for error, but it never actually returned a negative number, just 0 or 1. Now the function and its call sites agree that it's a bool. In a couple of places I've renamed variables called 'ret', because I don't like that name any more - it's unclear whether it means the return value (in preparation) for the _containing_ function or the return value received from a subroutine call, and occasionally I've accidentally used the same variable for both and introduced a bug. So where one of those got in my way, I've renamed it to 'toret' or 'retd' (the latter short for 'returned') in line with my usual modern practice, but I haven't done a thorough job of finding all of them. Finally, one amusing side effect of doing this is that I've had to separate quite a few chained assignments. It used to be perfectly fine to write 'a = b = c = TRUE' when a,b,c were int and TRUE was just a the 'true' defined by stdbool.h, that idiom provokes a warning from gcc: 'suggest parentheses around assignment used as truth value'!

Centralise key escape sequences into terminal.c. A long time ago, in commit 4d77b6567, I moved the generation of the arrow-key escape sequences into a function format_arrow_key(). Mostly the reason for that was a special purpose I had in mind at the time which involved auto-generating the same sequences in response to things other than a keypress, but I always thought it would be nice to centralise a lot more of PuTTY's complicated keyboard handling in the same way - at least the handling of the function keys and their numerous static and dynamic config options. In this year's general spirit of tidying up and refactoring, I think it's finally time. So here I introduce three more centralised functions for dealing with the numbered function keys, the small keypad (Ins, Home, PgUp etc) and the numeric keypad. Lots of horrible and duplicated code from the key handling functions in window.c and gtkwin.c is now more sensibly centralised: each platform keyboard handler concerns itself with the local format of a keyboard event and platform-specific enumeration of key codes, and once it's decided what the logical key press actually _is_, it hands off to the new functions in terminal.c to generate the appropriate escape code. Mostly this is intended to be a refactoring without functional change, leaving the keyboard handling how it's always been. But in cases where the Windows and GTK handlers were accidentally inconsistent, I've fixed the inconsistency rather than carefully keeping both sides how they were. Known consistency fixes: - swapping the arrow keys between normal (ESC [ A) and application (ESC O A) is now done by pressing Ctrl with them, and _not_ by pressing Shift. That was how it was always supposed to work, and how it's worked on GTK all along, but on Windows it's been done by Shift as well since 2010, due to a bug at the call site of format_arrow_key() introduced when I originally wrote that function. - in Xterm function key mode plus application keypad mode, the /*- keys on the numeric keypad now send ESC O {o,j,m} in place of ESC O {Q,R,S}. That's how the Windows keyboard handler has worked all along (it was a deliberate behaviour tweak for the Xterm-like function key mode, because in that mode ESC O {Q,R,S} are generated by F2-F4). But the GTK keyboard handler omitted that particular special case and was still sending ESC O {Q,R,S} for those keys in all application keypad modes. - also in Xterm function key mode plus app keypad mode, we only generates the app-keypad escape sequences if Num Lock is on; with Num Lock off, the numeric keypad becomes arrow keys and Home/End/etc, just as it would in non-app-keypad mode. Windows has done this all along, but again, GTK lacked that special case.

Post-release destabilisation! Completely remove the struct type 'Config' in putty.h, which stores all PuTTY's settings and includes an arbitrary length limit on every single one of those settings which is stored in string form. In place of it is 'Conf', an opaque data type everywhere outside the new file conf.c, which stores a list of (key, value) pairs in which every key contains an integer identifying a configuration setting, and for some of those integers the key also contains extra parts (so that, for instance, CONF_environmt is a string-to-string mapping). Everywhere that a Config was previously used, a Conf is now; everywhere there was a Config structure copy, conf_copy() is called; every lookup, adjustment, load and save operation on a Config has been rewritten; and there's a mechanism for serialising a Conf into a binary blob and back for use with Duplicate Session. User-visible effects of this change _should_ be minimal, though I don't doubt I've introduced one or two bugs here and there which will eventually be found. The _intended_ visible effects of this change are that all arbitrary limits on configuration strings and lists (e.g. limit on number of port forwardings) should now disappear; that list boxes in the configuration will now be displayed in a sorted order rather than the arbitrary order in which they were added to the list (since the underlying data structure is now a sorted tree234 rather than an ad-hoc comma-separated string); and one more specific change, which is that local and dynamic port forwardings on the same port number are now mutually exclusive in the configuration (putting 'D' in the key rather than the value was a mistake in the first place). One other reorganisation as a result of this is that I've moved all the dialog.c standard handlers (dlg_stdeditbox_handler and friends) out into config.c, because I can't really justify calling them generic any more. When they took a pointer to an arbitrary structure type and the offset of a field within that structure, they were independent of whether that structure was a Config or something completely different, but now they really do expect to talk to a Conf, which can _only_ be used for PuTTY configuration, so I've renamed them all things like conf_editbox_handler and moved them out of the nominally independent dialog-box management module into the PuTTY-specific config.c.

Switch some Conf settings over to being bool. I think this is the full set of things that ought logically to be boolean. One annoyance is that quite a few radio-button controls in config.c address Conf fields that are now bool rather than int, which means that the shared handler function can't just access them all with conf_{get,set}_int. Rather than back out the rigorous separation of int and bool in conf.c itself, I've just added a similar alternative handler function for the bool-typed ones.

Fix handling of Return and keypad Enter. The recent rewriting in both the GTK and Windows keyboard handlers left the keypad 'Enter' key in a bad state, when no override is enabled that causes it to generate an escape sequence. On Windows, a series of fallbacks was causing it to generate \r regardless of configuration, whereas in Telnet mode it should default to generating the special Telnet new-line sequence, and in response to ESC[20h (enabling term->cr_lf_return) it should generate \r\n. On GTK, it wasn't generating anything _at all_, and also, I can't see any evidence that the GTK keyboard handler had ever remembered to implement the cr_lf_return mode. Now Keypad Enter in non-escape-sequence mode should behave just like Return, on both platforms.

HKL kbd_layout = GetKeyboardLayout(0);
Switch to translating keystrokes using ToUnicodeEx rather than ToAsciiEx, where possible. This enables support for keys which generate Unicode characters that aren't in the system code page, which seems to me like a perverse way for Windows to have set up the system code page but apparently does happen, e.g. (I'm told) U+0219 and U+021B on Romanian keyboards. Patch mostly due to Andrei Damian-Fekete. [originally from svn r9942]

Post-release destabilisation! Completely remove the struct type 'Config' in putty.h, which stores all PuTTY's settings and includes an arbitrary length limit on every single one of those settings which is stored in string form. In place of it is 'Conf', an opaque data type everywhere outside the new file conf.c, which stores a list of (key, value) pairs in which every key contains an integer identifying a configuration setting, and for some of those integers the key also contains extra parts (so that, for instance, CONF_environmt is a string-to-string mapping). Everywhere that a Config was previously used, a Conf is now; everywhere there was a Config structure copy, conf_copy() is called; every lookup, adjustment, load and save operation on a Config has been rewritten; and there's a mechanism for serialising a Conf into a binary blob and back for use with Duplicate Session. User-visible effects of this change _should_ be minimal, though I don't doubt I've introduced one or two bugs here and there which will eventually be found. The _intended_ visible effects of this change are that all arbitrary limits on configuration strings and lists (e.g. limit on number of port forwardings) should now disappear; that list boxes in the configuration will now be displayed in a sorted order rather than the arbitrary order in which they were added to the list (since the underlying data structure is now a sorted tree234 rather than an ad-hoc comma-separated string); and one more specific change, which is that local and dynamic port forwardings on the same port number are now mutually exclusive in the configuration (putting 'D' in the key rather than the value was a mistake in the first place). One other reorganisation as a result of this is that I've moved all the dialog.c standard handlers (dlg_stdeditbox_handler and friends) out into config.c, because I can't really justify calling them generic any more. When they took a pointer to an arbitrary structure type and the offset of a field within that structure, they were independent of whether that structure was a Config or something completely different, but now they really do expect to talk to a Conf, which can _only_ be used for PuTTY configuration, so I've renamed them all things like conf_editbox_handler and moved them out of the nominally independent dialog-box management module into the PuTTY-specific config.c.

Major destabilisation, phase 1. In this phase I've moved (I think) all the global and function-static variables out of terminal.c into a dynamically allocated data structure. Note that this does not yet confer the ability to run more than one of them in the same process, because other things (the line discipline, the back end) are still global, and also in particular the address of the dynamically allocated terminal-data structure is held in a global variable `term'. But what I've got here represents a reasonable stopping point at which to check things in. In _theory_ this should all still work happily, on both Unix and Windows. In practice, who knows?

/* Sanitize the number pad if not using a PC NumPad */
Post-release destabilisation! Completely remove the struct type 'Config' in putty.h, which stores all PuTTY's settings and includes an arbitrary length limit on every single one of those settings which is stored in string form. In place of it is 'Conf', an opaque data type everywhere outside the new file conf.c, which stores a list of (key, value) pairs in which every key contains an integer identifying a configuration setting, and for some of those integers the key also contains extra parts (so that, for instance, CONF_environmt is a string-to-string mapping). Everywhere that a Config was previously used, a Conf is now; everywhere there was a Config structure copy, conf_copy() is called; every lookup, adjustment, load and save operation on a Config has been rewritten; and there's a mechanism for serialising a Conf into a binary blob and back for use with Duplicate Session. User-visible effects of this change _should_ be minimal, though I don't doubt I've introduced one or two bugs here and there which will eventually be found. The _intended_ visible effects of this change are that all arbitrary limits on configuration strings and lists (e.g. limit on number of port forwardings) should now disappear; that list boxes in the configuration will now be displayed in a sorted order rather than the arbitrary order in which they were added to the list (since the underlying data structure is now a sorted tree234 rather than an ad-hoc comma-separated string); and one more specific change, which is that local and dynamic port forwardings on the same port number are now mutually exclusive in the configuration (putting 'D' in the key rather than the value was a mistake in the first place). One other reorganisation as a result of this is that I've moved all the dialog.c standard handlers (dlg_stdeditbox_handler and friends) out into config.c, because I can't really justify calling them generic any more. When they took a pointer to an arbitrary structure type and the offset of a field within that structure, they were independent of whether that structure was a Config or something completely different, but now they really do expect to talk to a Conf, which can _only_ be used for PuTTY configuration, so I've renamed them all things like conf_editbox_handler and moved them out of the nominally independent dialog-box management module into the PuTTY-specific config.c.

GUI PuTTY: stop using the global 'hwnd'. This was the difficult part of cleaning up that global variable. The main Windows PuTTY GUI is split between source files, so that _does_ actually need to refer to the main window from multiple places. But all the places where windlg.c needed to use 'hwnd' are seat methods, so they were already receiving a Seat pointer as a parameter. In other words, the methods of the Windows GUI Seat were already split between source files. So it seems only fair that they should be able to share knowledge of the seat's data as well. Hence, I've created a small 'WinGuiSeat' structure which both window.c and windlg.c can see the layout of, and put the main terminal window handle in there. Then the seat methods implemented in windlg.c, like win_seat_verify_ssh_host_key, can use container_of to turn the Seat pointer parameter back into the address of that structure, just as the methods in window.c can do (even though they currently don't need to). (Who knows: now that it _exists_, perhaps that structure can be gradually expanded in future to turn it into a proper encapsulation of all the Windows frontend's state, like we should have had all along...) I've also moved the Windows GUI LogPolicy implementation into the same object (i.e. WinGuiSeat implements both traits at once). That allows win_gui_logging_error to recover the same WinGuiSeat from its input LogPolicy pointer, which means it can get from there to the Seat facet of the same object, so that I don't need the extern variable 'win_seat' any more either.

Add GUI configuration for choice of clipboards. On all platforms, you can now configure which clipboard the mouse pastes from, which clipboard Ctrl-Ins and Shift-Ins access, and which Ctrl-Shift-C and Ctrl-Shift-V access. In each case, the options are: - nothing at all - a clipboard which is implicitly written by the act of mouse selection (the PRIMARY selection on X, CLIP_LOCAL everywhere else) - the standard clipboard written by explicit copy/paste UI actions (CLIPBOARD on X, the unique system clipboard elsewhere). Also, you can control whether selecting text with the mouse _also_ writes to the explicitly accessed clipboard. The wording of the various messages changes between platforms, but the basic UI shape is the same everywhere.

Switch some Conf settings over to being bool. I think this is the full set of things that ought logically to be boolean. One annoyance is that quite a few radio-button controls in config.c address Conf fields that are now bool rather than int, which means that the shared handler function can't just access them all with conf_{get,set}_int. Rather than back out the rigorous separation of int and bool in conf.c itself, I've just added a similar alternative handler function for the bool-typed ones.

GUI PuTTY: stop using the global 'hwnd'. This was the difficult part of cleaning up that global variable. The main Windows PuTTY GUI is split between source files, so that _does_ actually need to refer to the main window from multiple places. But all the places where windlg.c needed to use 'hwnd' are seat methods, so they were already receiving a Seat pointer as a parameter. In other words, the methods of the Windows GUI Seat were already split between source files. So it seems only fair that they should be able to share knowledge of the seat's data as well. Hence, I've created a small 'WinGuiSeat' structure which both window.c and windlg.c can see the layout of, and put the main terminal window handle in there. Then the seat methods implemented in windlg.c, like win_seat_verify_ssh_host_key, can use container_of to turn the Seat pointer parameter back into the address of that structure, just as the methods in window.c can do (even though they currently don't need to). (Who knows: now that it _exists_, perhaps that structure can be gradually expanded in future to turn it into a proper encapsulation of all the Windows frontend's state, like we should have had all along...) I've also moved the Windows GUI LogPolicy implementation into the same object (i.e. WinGuiSeat implements both traits at once). That allows win_gui_logging_error to recover the same WinGuiSeat from its input LogPolicy pointer, which means it can get from there to the Seat facet of the same object, so that I don't need the extern variable 'win_seat' any more either.

Turn Backend into a sensible classoid. Nearly every part of the code that ever handles a full backend structure has historically done it using a pair of pointer variables, one pointing at a constant struct full of function pointers, and the other pointing to a 'void *' state object that's passed to each of those. While I'm modernising the rest of the code, this seems like a good time to turn that into the same more or less type-safe and less cumbersome system as I'm using for other parts of the code, such as Socket, Plug, BinaryPacketProtocol and so forth: the Backend structure contains a vtable pointer, and a system of macro wrappers handles dispatching through that vtable.

Rework special-commands system to add an integer argument. In order to list cross-certifiable host keys in the GUI specials menu, the SSH backend has been inventing new values on the end of the Telnet_Special enumeration, starting from the value TS_LOCALSTART. This is inelegant, and also makes it awkward to break up special handlers (e.g. to dispatch different specials to different SSH layers), since if all you know about a special is that it's somewhere in the TS_LOCALSTART+n space, you can't tell what _general kind_ of thing it is. Also, if I ever need another open-ended set of specials in future, I'll have to remember which TS_LOCALSTART+n codes are in which set. So here's a revamp that causes every special to take an extra integer argument. For all previously numbered specials, this argument is passed as zero and ignored, but there's a new main special code for SSH host key cross-certification, in which the integer argument is an index into the backend's list of available keys. TS_LOCALSTART is now a thing of the past: if I need any other open-ended sets of specials in future, I can add a new top-level code with a nicely separated space of arguments. While I'm at it, I've removed the legacy misnomer 'Telnet_Special' from the code completely; the enum is now SessionSpecialCode, the struct containing full details of a menu entry is SessionSpecial, and the enum values now start SS_ rather than TS_.

Centralise key escape sequences into terminal.c. A long time ago, in commit 4d77b6567, I moved the generation of the arrow-key escape sequences into a function format_arrow_key(). Mostly the reason for that was a special purpose I had in mind at the time which involved auto-generating the same sequences in response to things other than a keypress, but I always thought it would be nice to centralise a lot more of PuTTY's complicated keyboard handling in the same way - at least the handling of the function keys and their numerous static and dynamic config options. In this year's general spirit of tidying up and refactoring, I think it's finally time. So here I introduce three more centralised functions for dealing with the numbered function keys, the small keypad (Ins, Home, PgUp etc) and the numeric keypad. Lots of horrible and duplicated code from the key handling functions in window.c and gtkwin.c is now more sensibly centralised: each platform keyboard handler concerns itself with the local format of a keyboard event and platform-specific enumeration of key codes, and once it's decided what the logical key press actually _is_, it hands off to the new functions in terminal.c to generate the appropriate escape code. Mostly this is intended to be a refactoring without functional change, leaving the keyboard handling how it's always been. But in cases where the Windows and GTK handlers were accidentally inconsistent, I've fixed the inconsistency rather than carefully keeping both sides how they were. Known consistency fixes: - swapping the arrow keys between normal (ESC [ A) and application (ESC O A) is now done by pressing Ctrl with them, and _not_ by pressing Shift. That was how it was always supposed to work, and how it's worked on GTK all along, but on Windows it's been done by Shift as well since 2010, due to a bug at the call site of format_arrow_key() introduced when I originally wrote that function. - in Xterm function key mode plus application keypad mode, the /*- keys on the numeric keypad now send ESC O {o,j,m} in place of ESC O {Q,R,S}. That's how the Windows keyboard handler has worked all along (it was a deliberate behaviour tweak for the Xterm-like function key mode, because in that mode ESC O {Q,R,S} are generated by F2-F4). But the GTK keyboard handler omitted that particular special case and was still sending ESC O {Q,R,S} for those keys in all application keypad modes. - also in Xterm function key mode plus app keypad mode, we only generates the app-keypad escape sequences if Num Lock is on; with Num Lock off, the numeric keypad becomes arrow keys and Home/End/etc, just as it would in non-app-keypad mode. Windows has done this all along, but again, GTK lacked that special case.

Remove ASCII fallback in format_numeric_keypad_key(). TranslateKey() on Windows passed all numeric-keypad key events to this function in terminal.c, and accepted whatever it gave back. That included the handling for the trivial case of the numeric keypad, when Num Lock is on and application keypad mode hasn't overridden it, so that the keypad should be returning actual digits. In that case, format_numeric_keypad_key() itself was returning the same ASCII character I had passed in to it as a keypad identifier, and TranslateKey was returning that in turn as the final translation. Unfortunately, that means that with Num Lock on, the numeric keypad translates into what _I_ used as the logical keypad codes inside the source code, not what the local keyboard layout thinks are the right codes. In particular, the key I identified as keypad '.' would render as '.' even on a German keyboard where it ought to produce ','. Fixed by removing the fallback case in format_numeric_keypad_key() itself, so now it returns the empty string if it didn't produce an escape sequence as its translation. Instead, the special case is in window.c, which checks for a zero-length output string and handles it by falling through to the keyboard-layout specific ToUnicode code further down TranslateKey(). On the GTK side, no change is needed here: the GTK keyboard handler does things in the opposite order, by trying the local input method _first_ (unless it can see a reason up front to override it), and only calling format_numeric_keypad_key() if that didn't provide a translation. So the fallback ASCII translation in the latter was already not used.

Fix handling of Return and keypad Enter. The recent rewriting in both the GTK and Windows keyboard handlers left the keypad 'Enter' key in a bad state, when no override is enabled that causes it to generate an escape sequence. On Windows, a series of fallbacks was causing it to generate \r regardless of configuration, whereas in Telnet mode it should default to generating the special Telnet new-line sequence, and in response to ESC[20h (enabling term->cr_lf_return) it should generate \r\n. On GTK, it wasn't generating anything _at all_, and also, I can't see any evidence that the GTK keyboard handler had ever remembered to implement the cr_lf_return mode.

That was how it was always supposed to work, and how it's worked on GTK all along, but on Windows it's been done by Shift as well since 2010, due to a bug at the call site of format_arrow_key() introduced when I originally wrote that function. - in Xterm function key mode plus application keypad mode, the /*- keys on the numeric keypad now send ESC O {o,j,m} in place of ESC O {Q,R,S}. That's how the Windows keyboard handler has worked all along (it was a deliberate behaviour tweak for the Xterm-like function key mode, because in that mode ESC O {Q,R,S} are generated by F2-F4). But the GTK keyboard handler omitted that particular special case and was still sending ESC O {Q,R,S} for those keys in all application keypad modes. - also in Xterm function key mode plus app keypad mode, we only generates the app-keypad escape sequences if Num Lock is on; with Num Lock off, the numeric keypad becomes arrow keys and Home/End/etc, just as it would in non-app-keypad mode. Windows has done this all along, but again, GTK lacked that special case.

The number of people has been steadily increasing who read our source code with an editor that thinks tab stops are 4 spaces apart, as opposed to the traditional tty-derived 8 that the PuTTY code expects. So I've been wondering for ages about just fixing it, and switching to a spaces-only policy throughout the code. And I recently found out about 'git blame -w', which should make this change not too disruptive for the purposes of source-control archaeology; so perhaps now is the time. While I'm at it, I've also taken the opportunity to remove all the trailing spaces from source lines (on the basis that git dislikes them, and is the only thing that seems to have a strong opinion one way or the other).

Centralise key escape sequences into terminal.c. A long time ago, in commit 4d77b6567, I moved the generation of the arrow-key escape sequences into a function format_arrow_key(). Mostly the reason for that was a special purpose I had in mind at the time which involved auto-generating the same sequences in response to things other than a keypress, but I always thought it would be nice to centralise a lot more of PuTTY's complicated keyboard handling in the same way - at least the handling of the function keys and their numerous static and dynamic config options. In this year's general spirit of tidying up and refactoring, I think it's finally time. So here I introduce three more centralised functions for dealing with the numbered function keys, the small keypad (Ins, Home, PgUp etc) and the numeric keypad. Lots of horrible and duplicated code from the key handling functions in window.c and gtkwin.c is now more sensibly centralised: each platform keyboard handler concerns itself with the local format of a keyboard event and platform-specific enumeration of key codes, and once it's decided what the logical key press actually _is_, it hands off to the new functions in terminal.c to generate the appropriate escape code. Mostly this is intended to be a refactoring without functional change, leaving the keyboard handling how it's always been. But in cases where the Windows and GTK handlers were accidentally inconsistent, I've fixed the inconsistency rather than carefully keeping both sides how they were. Known consistency fixes: - swapping the arrow keys between normal (ESC [ A) and application (ESC O A) is now done by pressing Ctrl with them, and _not_ by pressing Shift. That was how it was always supposed to work, and how it's worked on GTK all along, but on Windows it's been done by Shift as well since 2010, due to a bug at the call site of format_arrow_key() introduced when I originally wrote that function. - in Xterm function key mode plus application keypad mode, the /*- keys on the numeric keypad now send ESC O {o,j,m} in place of ESC O {Q,R,S}.

Fix handling of Return and keypad Enter. The recent rewriting in both the GTK and Windows keyboard handlers left the keypad 'Enter' key in a bad state, when no override is enabled that causes it to generate an escape sequence. On Windows, a series of fallbacks was causing it to generate \r regardless of configuration, whereas in Telnet mode it should default to generating the special Telnet new-line sequence, and in response to ESC[20h (enabling term->cr_lf_return) it should generate \r\n. On GTK, it wasn't generating anything _at all_, and also, I can't see any evidence that the GTK keyboard handler had ever remembered to implement the cr_lf_return mode. Now Keypad Enter in non-escape-sequence mode should behave just like Return, on both platforms.

Refactor terminal input to remove ldiscucs.c. The functions that previously lived in it now live in terminal.c itself; they've been renamed term_keyinput and term_keyinputw, and their function is to add data to the terminal's user input buffer from a char or wchar_t string respectively. They sit more comfortably in terminal.c anyway, because their whole point is to translate into the character encoding that the terminal is currently configured to use. Also, making them part of the terminal code means they can also take care of calling term_seen_key_event(), which simplifies most of the call sites in the GTK and Windows front ends. Generation of text _inside_ terminal.c, from responses to query escape sequences, is therefore not done by calling those external entry points: we send those responses directly to the ldisc, so that they don't count as keypresses for all the user-facing purposes like bell overload handling and scrollback reset. To make _that_ convenient, I've arranged that most of the code that previously lived in lpage_send and luni_send is now in separate translation functions, so those can still be called from situations where you're not going to do the default thing with the translated data. (However, pasted data _does_ still count as close enough to a keypress to call term_seen_key_event - but it clears the 'interactive' flag when the data is passed on to the line discipline, which tweaks a minor detail of control-char handling in line ending mode but mostly just means pastes aren't interrupted.)

They sit more comfortably in terminal.c anyway, because their whole point is to translate into the character encoding that the terminal is currently configured to use. Also, making them part of the terminal code means they can also take care of calling term_seen_key_event(), which simplifies most of the call sites in the GTK and Windows front ends. Generation of text _inside_ terminal.c, from responses to query escape sequences, is therefore not done by calling those external entry points: we send those responses directly to the ldisc, so that they don't count as keypresses for all the user-facing purposes like bell overload handling and scrollback reset. To make _that_ convenient, I've arranged that most of the code that previously lived in lpage_send and luni_send is now in separate translation functions, so those can still be called from situations where you're not going to do the default thing with the translated data. (However, pasted data _does_ still count as close enough to a keypress to call term_seen_key_event - but it clears the 'interactive' flag when the data is passed on to the line discipline, which tweaks a minor detail of control-char handling in line ending mode but mostly just means pastes aren't interrupted.)

Whitespace rationalisation of entire code base. The number of people has been steadily increasing who read our source code with an editor that thinks tab stops are 4 spaces apart, as opposed to the traditional tty-derived 8 that the PuTTY code expects. So I've been wondering for ages about just fixing it, and switching to a spaces-only policy throughout the code. And I recently found out about 'git blame -w', which should make this change not too disruptive for the purposes of source-control archaeology; so perhaps now is the time. While I'm at it, I've also taken the opportunity to remove all the trailing spaces from source lines (on the basis that git dislikes them, and is the only thing that seems to have a strong opinion one way or the other).

Switch some Conf settings over to being bool. I think this is the full set of things that ought logically to be boolean. One annoyance is that quite a few radio-button controls in config.c address Conf fields that are now bool rather than int, which means that the shared handler function can't just access them all with conf_{get,set}_int. Rather than back out the rigorous separation of int and bool in conf.c itself, I've just added a similar alternative handler function for the bool-typed ones.

Remove the 'Frontend' type and replace it with a vtable. After the recent Seat and LogContext revamps, _nearly_ all the remaining uses of the type 'Frontend' were in terminal.c, which needs all sorts of interactions with the GUI window the terminal lives in, from the obvious (actually drawing text on the window, reading and writing the clipboard) to the obscure (minimising, maximising and moving the window in response to particular escape sequences).

So now the name 'Frontend' no longer exists in the code base at all, and everywhere one used to be used, it's completely clear whether it was operating in one of Frontend's three abstract roles (and if so, which), or whether it was specific to a particular implementation. Another type that's disappeared is 'Context', which used to be a typedef defined to something different on each platform, describing whatever short-lived resources were necessary to draw on the terminal window: the front end would provide a ready-made one when calling term_paint, and the terminal could request one with get_ctx/free_ctx if it wanted to do proactive window updates. Now that drawing context lives inside the TermWin itself, because there was never any need to have two of those contexts live at the same time.

GUI PuTTY: stop using the global 'hwnd'. This was the difficult part of cleaning up that global variable. The main Windows PuTTY GUI is split between source files, so that _does_ actually need to refer to the main window from multiple places. But all the places where windlg.c needed to use 'hwnd' are seat methods, so they were already receiving a Seat pointer as a parameter. In other words, the methods of the Windows GUI Seat were already split between source files. So it seems only fair that they should be able to share knowledge of the seat's data as well. Hence, I've created a small 'WinGuiSeat' structure which both window.c and windlg.c can see the layout of, and put the main terminal window handle in there. Then the seat methods implemented in windlg.c, like win_seat_verify_ssh_host_key, can use container_of to turn the Seat pointer parameter back into the address of that structure, just as the methods in window.c can do (even though they currently don't need to). (Who knows: now that it _exists_, perhaps that structure can be gradually expanded in future to turn it into a proper encapsulation of all the Windows frontend's state, like we should have had all along...) I've also moved the Windows GUI LogPolicy implementation into the same object (i.e. WinGuiSeat implements both traits at once). That allows win_gui_logging_error to recover the same WinGuiSeat from its input LogPolicy pointer, which means it can get from there to the Seat facet of the same object, so that I don't need the extern variable 'win_seat' any more either.

Convert a lot of 'int' variables to 'bool'. My normal habit these days, in new code, is to treat int and bool as _almost_ completely separate types. I'm still willing to use C's implicit test for zero on an integer (e.g. 'if (!blob.len)' is fine, no need to spell it out as blob.len != 0), but generally, if a variable is going to be conceptually a boolean, I like to declare it bool and assign to it using 'true' or 'false' rather than 0 or 1. PuTTY is an exception, because it predates the C99 bool, and I've stuck to its existing coding style even when adding new code to it. But it's been annoying me more and more, so now that I've decided C99 bool is an acceptable thing to require from our toolchain in the first place, here's a quite thorough trawl through the source doing 'boolification'. Many variables and function parameters are now typed as bool rather than int; many assignments of 0 or 1 to those variables are now spelled 'true' or 'false'. I managed this thorough conversion with the help of a custom clang plugin that I wrote to trawl the AST and apply heuristics to point out where things might want changing. So I've even managed to do a decent job on parts of the code I haven't looked at in years! To make the plugin's work easier, I pushed platform front ends generally in the direction of using standard 'bool' in preference to platform-specific boolean types like Windows BOOL or GTK's gboolean; I've left the platform booleans in places they _have_ to be for the platform APIs to work right, but variables only used by my own code have been converted wherever I found them. In a few places there are int values that look very like booleans in _most_ of the places they're used, but have a rarely-used third value, or a distinction between different nonzero values that most users don't care about. In these cases, I've _removed_ uses of 'true' and 'false' for the return values, to emphasise that there's something more subtle going on than a simple boolean answer: - the 'multisel' field in dialog.h's list box structure, for which the GTK front end in particular recognises a difference between 1 and 2 but nearly everything else treats as boolean - the 'urgent' parameter to plug_receive, where 1 vs 2 tells you something about the specific location of the urgent pointer, but most clients only care about 0 vs 'something nonzero' - the return value of wc_match, where -1 indicates a syntax error in the wildcard. - the return values from SSH-1 RSA-key loading functions, which use -1 for 'wrong passphrase' and 0 for all other failures (so any caller which already knows it's not loading an _encrypted private_ key can treat them as boolean) - term->esc_query, and the 'query' parameter in toggle_mode in terminal.c, which _usually_ hold 0 for ESC[123h or 1 for ESC[?123h, but can also hold -1 for some other intervening character that we don't support. In a few places there's an integer that I haven't turned into a bool even though it really _can_ only take values 0 or 1 (and, as above, tried to make the call sites consistent in not calling those values true and false), on the grounds that I thought it would make it more confusing to imply that the 0 value was in some sense 'negative' or bad and the 1 positive or good: - the return value of plug_accepting uses the POSIXish convention of 0=success and nonzero=error; I think if I made it bool then I'd also want to reverse its sense, and that's a job for a separate piece of work. - the 'screen' parameter to lineptr() in terminal.c, where 0 and 1 represent the default and alternate screens. There's no obvious reason why one of those should be considered 'true' or 'positive' or 'success' - they're just indices - so I've left it as int. ssh_scp_recv had particularly confusing semantics for its previous int return value: its call sites used '<= 0' to check for error, but it never actually returned a negative number, just 0 or 1. Now the function and its call sites agree that it's a bool. In a couple of places I've renamed variables called 'ret', because I don't like that name any more - it's unclear whether it means the return value (in preparation) for the _containing_ function or the return value received from a subroutine call, and occasionally I've accidentally used the same variable for both and introduced a bug. So where one of those got in my way, I've renamed it to 'toret' or 'retd' (the latter short for 'returned') in line with my usual modern practice, but I haven't done a thorough job of finding all of them. Finally, one amusing side effect of doing this is that I've had to separate quite a few chained assignments. It used to be perfectly fine to write 'a = b = c = TRUE' when a,b,c were int and TRUE was just a the 'true' defined by stdbool.h, that idiom provokes a warning from gcc: 'suggest parentheses around assignment used as truth value'!

So now the name 'Frontend' no longer exists in the code base at all, and everywhere one used to be used, it's completely clear whether it was operating in one of Frontend's three abstract roles (and if so, which), or whether it was specific to a particular implementation. Another type that's disappeared is 'Context', which used to be a typedef defined to something different on each platform, describing whatever short-lived resources were necessary to draw on the terminal window: the front end would provide a ready-made one when calling term_paint, and the terminal could request one with get_ctx/free_ctx if it wanted to do proactive window updates. Now that drawing context lives inside the TermWin itself, because there was never any need to have two of those contexts live at the same time. (Another minor API change is that the window-title functions - both reading and writing - have had a missing 'const' added to their char * parameters / return values.) I don't expect this change to enable any particularly interesting new functionality (in particular, I have no plans that need more than one implementation of TermWin in the same application). But it completes the tidying-up that began with the Seat and LogContext rework.

Remove the 'Frontend' type and replace it with a vtable. After the recent Seat and LogContext revamps, _nearly_ all the remaining uses of the type 'Frontend' were in terminal.c, which needs all sorts of interactions with the GUI window the terminal lives in, from the obvious (actually drawing text on the window, reading and writing the clipboard) to the obscure (minimising, maximising and moving the window in response to particular escape sequences). All of those functions are now provided by an abstraction called TermWin. The few remaining uses of Frontend after _that_ are internal to a particular platform directory, so as to spread the implementation of that particular kind of Frontend between multiple source files; so I've renamed all of those so that they take a more specifically named type that refers to the particular implementation rather than the general abstraction.

Centralise palette setup into terminal.c. Now terminal.c makes nearly all the decisions about what the colour palette should actually contain: it does the job of reading the GUI-configurable colours out of Conf, and also the job of making up the rest of the xterm-256 palette. The only exception is that TermWin can provide a method to override some of the default colours, which on Windows is used to implement the 'Use system colours' config option. This saves code overall, partly because the front ends don't have to be able to send palette data back to the Terminal any more (the Terminal keeps the master copy and can answer palette-query escape sequences from its own knowledge), and also because now there's only one copy of the xterm-256 palette setup code (previously gtkwin.c and window.c each had their own version of it). In this rewrite, I've also introduced a multi-layered storage system for the palette data in Terminal. One layer contains the palette information derived from Conf; the next contains platform overrides (currently just Windows's 'Use system colours'); the last one contains overrides set by escape sequences in the middle of the session. The topmost two layers can each _conditionally_ override the ones below. As a result, if a server-side application manually resets (say) the default fg and bg colours in mid-session to something that works well in a particular application, those changes won't be wiped out by a change in the Windows system colours or the Conf, which they would have been before. Instead, changes in Conf or the system colours alter the lower layers of the structure, but then when palette_rebuild is called, the upper layer continues to override them, until a palette reset (ESC]R) or terminal reset (e.g. ESC c) removes those upper-layer changes. This seems like a more consistent strategy, in that the same set of configuration settings will produce the same end result regardless of what order they were applied in. The palette-related methods in TermWin have had a total rework. palette_get and palette_reset are both gone; palette_set can now set a contiguous range of colours in one go; and the new palette_get_overrides replaces window.c's old systopalette().

Support OSC 4 terminal colour-palette queries. Markus Gans points out that some applications which (not at all unreasonably) don't trust $TERM to tell them the full capabilities of their terminal will use the sequence "OSC 4 ; nn ; ? BEL" to ask for the colour-palette value in position nn, and they may not particularly care _what_ the results are but they will use them to decide whether the right number of colour palette entries even exist.

GUI PuTTY: stop using the global 'hwnd'. This was the difficult part of cleaning up that global variable. The main Windows PuTTY GUI is split between source files, so that _does_ actually need to refer to the main window from multiple places. But all the places where windlg.c needed to use 'hwnd' are seat methods, so they were already receiving a Seat pointer as a parameter. In other words, the methods of the Windows GUI Seat were already split between source files. So it seems only fair that they should be able to share knowledge of the seat's data as well. Hence, I've created a small 'WinGuiSeat' structure which both window.c and windlg.c can see the layout of, and put the main terminal window handle in there. Then the seat methods implemented in windlg.c, like win_seat_verify_ssh_host_key, can use container_of to turn the Seat pointer parameter back into the address of that structure, just as the methods in window.c can do (even though they currently don't need to). (Who knows: now that it _exists_, perhaps that structure can be gradually expanded in future to turn it into a proper encapsulation of all the Windows frontend's state, like we should have had all along...) I've also moved the Windows GUI LogPolicy implementation into the same object (i.e. WinGuiSeat implements both traits at once). That allows win_gui_logging_error to recover the same WinGuiSeat from its input LogPolicy pointer, which means it can get from there to the Seat facet of the same object, so that I don't need the extern variable 'win_seat' any more either.

Convert a lot of 'int' variables to 'bool'. My normal habit these days, in new code, is to treat int and bool as _almost_ completely separate types. I'm still willing to use C's implicit test for zero on an integer (e.g. 'if (!blob.len)' is fine, no need to spell it out as blob.len != 0), but generally, if a variable is going to be conceptually a boolean, I like to declare it bool and assign to it using 'true' or 'false' rather than 0 or 1. PuTTY is an exception, because it predates the C99 bool, and I've stuck to its existing coding style even when adding new code to it. But it's been annoying me more and more, so now that I've decided C99 bool is an acceptable thing to require from our toolchain in the first place, here's a quite thorough trawl through the source doing 'boolification'. Many variables and function parameters are now typed as bool rather than int; many assignments of 0 or 1 to those variables are now spelled 'true' or 'false'. I managed this thorough conversion with the help of a custom clang plugin that I wrote to trawl the AST and apply heuristics to point out where things might want changing. So I've even managed to do a decent job on parts of the code I haven't looked at in years! To make the plugin's work easier, I pushed platform front ends generally in the direction of using standard 'bool' in preference to platform-specific boolean types like Windows BOOL or GTK's gboolean; I've left the platform booleans in places they _have_ to be for the platform APIs to work right, but variables only used by my own code have been converted wherever I found them. In a few places there are int values that look very like booleans in _most_ of the places they're used, but have a rarely-used third value, or a distinction between different nonzero values that most users don't care about. In these cases, I've _removed_ uses of 'true' and 'false' for the return values, to emphasise that there's something more subtle going on than a simple boolean answer: - the 'multisel' field in dialog.h's list box structure, for which the GTK front end in particular recognises a difference between 1 and 2 but nearly everything else treats as boolean - the 'urgent' parameter to plug_receive, where 1 vs 2 tells you something about the specific location of the urgent pointer, but most clients only care about 0 vs 'something nonzero' - the return value of wc_match, where -1 indicates a syntax error in the wildcard. - the return values from SSH-1 RSA-key loading functions, which use -1 for 'wrong passphrase' and 0 for all other failures (so any caller which already knows it's not loading an _encrypted private_ key can treat them as boolean) - term->esc_query, and the 'query' parameter in toggle_mode in terminal.c, which _usually_ hold 0 for ESC[123h or 1 for ESC[?123h, but can also hold -1 for some other intervening character that we don't support. In a few places there's an integer that I haven't turned into a bool even though it really _can_ only take values 0 or 1 (and, as above, tried to make the call sites consistent in not calling those values true and false), on the grounds that I thought it would make it more confusing to imply that the 0 value was in some sense 'negative' or bad and the 1 positive or good: - the return value of plug_accepting uses the POSIXish convention of 0=success and nonzero=error; I think if I made it bool then I'd also want to reverse its sense, and that's a job for a separate piece of work. - the 'screen' parameter to lineptr() in terminal.c, where 0 and 1 represent the default and alternate screens. There's no obvious reason why one of those should be considered 'true' or 'positive' or 'success' - they're just indices - so I've left it as int. ssh_scp_recv had particularly confusing semantics for its previous int return value: its call sites used '<= 0' to check for error, but it never actually returned a negative number, just 0 or 1. Now the function and its call sites agree that it's a bool. In a couple of places I've renamed variables called 'ret', because I don't like that name any more - it's unclear whether it means the return value (in preparation) for the _containing_ function or the return value received from a subroutine call, and occasionally I've accidentally used the same variable for both and introduced a bug. So where one of those got in my way, I've renamed it to 'toret' or 'retd' (the latter short for 'returned') in line with my usual modern practice, but I haven't done a thorough job of finding all of them. Finally, one amusing side effect of doing this is that I've had to separate quite a few chained assignments. It used to be perfectly fine to write 'a = b = c = TRUE' when a,b,c were int and TRUE was just a the 'true' defined by stdbool.h, that idiom provokes a warning from gcc: 'suggest parentheses around assignment used as truth value'!

GUI PuTTY: stop using the global 'hwnd'. This was the difficult part of cleaning up that global variable. The main Windows PuTTY GUI is split between source files, so that _does_ actually need to refer to the main window from multiple places. But all the places where windlg.c needed to use 'hwnd' are seat methods, so they were already receiving a Seat pointer as a parameter. In other words, the methods of the Windows GUI Seat were already split between source files. So it seems only fair that they should be able to share knowledge of the seat's data as well. Hence, I've created a small 'WinGuiSeat' structure which both window.c and windlg.c can see the layout of, and put the main terminal window handle in there. Then the seat methods implemented in windlg.c, like win_seat_verify_ssh_host_key, can use container_of to turn the Seat pointer parameter back into the address of that structure, just as the methods in window.c can do (even though they currently don't need to). (Who knows: now that it _exists_, perhaps that structure can be gradually expanded in future to turn it into a proper encapsulation of all the Windows frontend's state, like we should have had all along...) I've also moved the Windows GUI LogPolicy implementation into the same object (i.e. WinGuiSeat implements both traits at once). That allows win_gui_logging_error to recover the same WinGuiSeat from its input LogPolicy pointer, which means it can get from there to the Seat facet of the same object, so that I don't need the extern variable 'win_seat' any more either.

Remove the 'Frontend' type and replace it with a vtable. After the recent Seat and LogContext revamps, _nearly_ all the remaining uses of the type 'Frontend' were in terminal.c, which needs all sorts of interactions with the GUI window the terminal lives in, from the obvious (actually drawing text on the window, reading and writing the clipboard) to the obscure (minimising, maximising and moving the window in response to particular escape sequences). All of those functions are now provided by an abstraction called TermWin. The few remaining uses of Frontend after _that_ are internal to a particular platform directory, so as to spread the implementation of that particular kind of Frontend between multiple source files; so I've renamed all of those so that they take a more specifically named type that refers to the particular implementation rather than the general abstraction. So now the name 'Frontend' no longer exists in the code base at all, and everywhere one used to be used, it's completely clear whether it was operating in one of Frontend's three abstract roles (and if so, which), or whether it was specific to a particular implementation. Another type that's disappeared is 'Context', which used to be a typedef defined to something different on each platform, describing whatever short-lived resources were necessary to draw on the terminal window: the front end would provide a ready-made one when calling term_paint, and the terminal could request one with get_ctx/free_ctx if it wanted to do proactive window updates. Now that drawing context lives inside the TermWin itself, because there was never any need to have two of those contexts live at the same time. (Another minor API change is that the window-title functions - both reading and writing - have had a missing 'const' added to their char * parameters / return values.) I don't expect this change to enable any particularly interesting new functionality (in particular, I have no plans that need more than one implementation of TermWin in the same application). But it completes the tidying-up that began with the Seat and LogContext rework.

Convert a lot of 'int' variables to 'bool'. My normal habit these days, in new code, is to treat int and bool as _almost_ completely separate types. I'm still willing to use C's implicit test for zero on an integer (e.g. 'if (!blob.len)' is fine, no need to spell it out as blob.len != 0), but generally, if a variable is going to be conceptually a boolean, I like to declare it bool and assign to it using 'true' or 'false' rather than 0 or 1. PuTTY is an exception, because it predates the C99 bool, and I've stuck to its existing coding style even when adding new code to it. But it's been annoying me more and more, so now that I've decided C99 bool is an acceptable thing to require from our toolchain in the first place, here's a quite thorough trawl through the source doing 'boolification'. Many variables and function parameters are now typed as bool rather than int; many assignments of 0 or 1 to those variables are now spelled 'true' or 'false'. I managed this thorough conversion with the help of a custom clang plugin that I wrote to trawl the AST and apply heuristics to point out where things might want changing. So I've even managed to do a decent job on parts of the code I haven't looked at in years! To make the plugin's work easier, I pushed platform front ends generally in the direction of using standard 'bool' in preference to platform-specific boolean types like Windows BOOL or GTK's gboolean; I've left the platform booleans in places they _have_ to be for the platform APIs to work right, but variables only used by my own code have been converted wherever I found them. In a few places there are int values that look very like booleans in _most_ of the places they're used, but have a rarely-used third value, or a distinction between different nonzero values that most users don't care about. In these cases, I've _removed_ uses of 'true' and 'false' for the return values, to emphasise that there's something more subtle going on than a simple boolean answer: - the 'multisel' field in dialog.h's list box structure, for which the GTK front end in particular recognises a difference between 1 and 2 but nearly everything else treats as boolean - the 'urgent' parameter to plug_receive, where 1 vs 2 tells you something about the specific location of the urgent pointer, but most clients only care about 0 vs 'something nonzero' - the return value of wc_match, where -1 indicates a syntax error in the wildcard. - the return values from SSH-1 RSA-key loading functions, which use -1 for 'wrong passphrase' and 0 for all other failures (so any caller which already knows it's not loading an _encrypted private_ key can treat them as boolean) - term->esc_query, and the 'query' parameter in toggle_mode in terminal.c, which _usually_ hold 0 for ESC[123h or 1 for ESC[?123h, but can also hold -1 for some other intervening character that we don't support. In a few places there's an integer that I haven't turned into a bool even though it really _can_ only take values 0 or 1 (and, as above, tried to make the call sites consistent in not calling those values true and false), on the grounds that I thought it would make it more confusing to imply that the 0 value was in some sense 'negative' or bad and the 1 positive or good: - the return value of plug_accepting uses the POSIXish convention of 0=success and nonzero=error; I think if I made it bool then I'd also want to reverse its sense, and that's a job for a separate piece of work. - the 'screen' parameter to lineptr() in terminal.c, where 0 and 1 represent the default and alternate screens.

Switch some Conf settings over to being bool. I think this is the full set of things that ought logically to be boolean. One annoyance is that quite a few radio-button controls in config.c address Conf fields that are now bool rather than int, which means that the shared handler function can't just access them all with conf_{get,set}_int. Rather than back out the rigorous separation of int and bool in conf.c itself, I've just added a similar alternative handler function for the bool-typed ones.

Centralise palette setup into terminal.c. Now terminal.c makes nearly all the decisions about what the colour palette should actually contain: it does the job of reading the GUI-configurable colours out of Conf, and also the job of making up the rest of the xterm-256 palette. The only exception is that TermWin can provide a method to override some of the default colours, which on Windows is used to implement the 'Use system colours' config option. This saves code overall, partly because the front ends don't have to be able to send palette data back to the Terminal any more (the Terminal keeps the master copy and can answer palette-query escape sequences from its own knowledge), and also because now there's only one copy of the xterm-256 palette setup code (previously gtkwin.c and window.c each had their own version of it). In this rewrite, I've also introduced a multi-layered storage system for the palette data in Terminal. One layer contains the palette information derived from Conf; the next contains platform overrides (currently just Windows's 'Use system colours'); the last one contains overrides set by escape sequences in the middle of the session. The topmost two layers can each _conditionally_ override the ones below. As a result, if a server-side application manually resets (say) the default fg and bg colours in mid-session to something that works well in a particular application, those changes won't be wiped out by a change in the Windows system colours or the Conf, which they would have been before. Instead, changes in Conf or the system colours alter the lower layers of the structure, but then when palette_rebuild is called, the upper layer continues to override them, until a palette reset (ESC]R) or terminal reset (e.g. ESC c) removes those upper-layer changes. This seems like a more consistent strategy, in that the same set of configuration settings will produce the same end result regardless of what order they were applied in. The palette-related methods in TermWin have had a total rework. palette_get and palette_reset are both gone; palette_set can now set a contiguous range of colours in one go; and the new palette_get_overrides replaces window.c's old systopalette().

Whitespace rationalisation of entire code base. The number of people has been steadily increasing who read our source code with an editor that thinks tab stops are 4 spaces apart, as opposed to the traditional tty-derived 8 that the PuTTY code expects. So I've been wondering for ages about just fixing it, and switching to a spaces-only policy throughout the code. And I recently found out about 'git blame -w', which should make this change not too disruptive for the purposes of source-control archaeology; so perhaps now is the time. While I'm at it, I've also taken the opportunity to remove all the trailing spaces from source lines (on the basis that git dislikes them, and is the only thing that seems to have a strong opinion one way or the other).

Add missing cast in RTF paste data construction. udata[uindex] is a wchar_t, so if we pass it to sprintf("%d") we should cast it to int (because who knows what primitive integer type that might have corresponded to otherwise).

GUI PuTTY: stop using the global 'hwnd'. This was the difficult part of cleaning up that global variable. The main Windows PuTTY GUI is split between source files, so that _does_ actually need to refer to the main window from multiple places. But all the places where windlg.c needed to use 'hwnd' are seat methods, so they were already receiving a Seat pointer as a parameter. In other words, the methods of the Windows GUI Seat were already split between source files. So it seems only fair that they should be able to share knowledge of the seat's data as well. Hence, I've created a small 'WinGuiSeat' structure which both window.c and windlg.c can see the layout of, and put the main terminal window handle in there. Then the seat methods implemented in windlg.c, like win_seat_verify_ssh_host_key, can use container_of to turn the Seat pointer parameter back into the address of that structure, just as the methods in window.c can do (even though they currently don't need to). (Who knows: now that it _exists_, perhaps that structure can be gradually expanded in future to turn it into a proper encapsulation of all the Windows frontend's state, like we should have had all along...) I've also moved the Windows GUI LogPolicy implementation into the same object (i.e. WinGuiSeat implements both traits at once). That allows win_gui_logging_error to recover the same WinGuiSeat from its input LogPolicy pointer, which means it can get from there to the Seat facet of the same object, so that I don't need the extern variable 'win_seat' any more either.

Instead of the various ad-hoc translation modes we had before, we now have a single `codepage' option which allows us to treat the incoming (and outgoing) text as any given character set, and locally we map that to Unicode and back.

GUI PuTTY: stop using the global 'hwnd'. This was the difficult part of cleaning up that global variable. The main Windows PuTTY GUI is split between source files, so that _does_ actually need to refer to the main window from multiple places. But all the places where windlg.c needed to use 'hwnd' are seat methods, so they were already receiving a Seat pointer as a parameter. In other words, the methods of the Windows GUI Seat were already split between source files. So it seems only fair that they should be able to share knowledge of the seat's data as well. Hence, I've created a small 'WinGuiSeat' structure which both window.c and windlg.c can see the layout of, and put the main terminal window handle in there. Then the seat methods implemented in windlg.c, like win_seat_verify_ssh_host_key, can use container_of to turn the Seat pointer parameter back into the address of that structure, just as the methods in window.c can do (even though they currently don't need to). (Who knows: now that it _exists_, perhaps that structure can be gradually expanded in future to turn it into a proper encapsulation of all the Windows frontend's state, like we should have had all along...) I've also moved the Windows GUI LogPolicy implementation into the same object (i.e. WinGuiSeat implements both traits at once). That allows win_gui_logging_error to recover the same WinGuiSeat from its input LogPolicy pointer, which means it can get from there to the Seat facet of the same object, so that I don't need the extern variable 'win_seat' any more either.

Convert a lot of 'int' variables to 'bool'. My normal habit these days, in new code, is to treat int and bool as _almost_ completely separate types. I'm still willing to use C's implicit test for zero on an integer (e.g. 'if (!blob.len)' is fine, no need to spell it out as blob.len != 0), but generally, if a variable is going to be conceptually a boolean, I like to declare it bool and assign to it using 'true' or 'false' rather than 0 or 1. PuTTY is an exception, because it predates the C99 bool, and I've stuck to its existing coding style even when adding new code to it. But it's been annoying me more and more, so now that I've decided C99 bool is an acceptable thing to require from our toolchain in the first place, here's a quite thorough trawl through the source doing 'boolification'. Many variables and function parameters are now typed as bool rather than int; many assignments of 0 or 1 to those variables are now spelled 'true' or 'false'. I managed this thorough conversion with the help of a custom clang plugin that I wrote to trawl the AST and apply heuristics to point out where things might want changing. So I've even managed to do a decent job on parts of the code I haven't looked at in years! To make the plugin's work easier, I pushed platform front ends generally in the direction of using standard 'bool' in preference to platform-specific boolean types like Windows BOOL or GTK's gboolean; I've left the platform booleans in places they _have_ to be for the platform APIs to work right, but variables only used by my own code have been converted wherever I found them. In a few places there are int values that look very like booleans in _most_ of the places they're used, but have a rarely-used third value, or a distinction between different nonzero values that most users don't care about. In these cases, I've _removed_ uses of 'true' and 'false' for the return values, to emphasise that there's something more subtle going on than a simple boolean answer: - the 'multisel' field in dialog.h's list box structure, for which the GTK front end in particular recognises a difference between 1 and 2 but nearly everything else treats as boolean - the 'urgent' parameter to plug_receive, where 1 vs 2 tells you something about the specific location of the urgent pointer, but most clients only care about 0 vs 'something nonzero' - the return value of wc_match, where -1 indicates a syntax error in the wildcard. - the return values from SSH-1 RSA-key loading functions, which use -1 for 'wrong passphrase' and 0 for all other failures (so any caller which already knows it's not loading an _encrypted private_ key can treat them as boolean) - term->esc_query, and the 'query' parameter in toggle_mode in terminal.c, which _usually_ hold 0 for ESC[123h or 1 for ESC[?123h, but can also hold -1 for some other intervening character that we don't support. In a few places there's an integer that I haven't turned into a bool even though it really _can_ only take values 0 or 1 (and, as above, tried to make the call sites consistent in not calling those values true and false), on the grounds that I thought it would make it more confusing to imply that the 0 value was in some sense 'negative' or bad and the 1 positive or good: - the return value of plug_accepting uses the POSIXish convention of 0=success and nonzero=error; I think if I made it bool then I'd also want to reverse its sense, and that's a job for a separate piece of work. - the 'screen' parameter to lineptr() in terminal.c, where 0 and 1 represent the default and alternate screens. There's no obvious reason why one of those should be considered 'true' or 'positive' or 'success' - they're just indices - so I've left it as int. ssh_scp_recv had particularly confusing semantics for its previous int return value: its call sites used '<= 0' to check for error, but it never actually returned a negative number, just 0 or 1. Now the function and its call sites agree that it's a bool. In a couple of places I've renamed variables called 'ret', because I don't like that name any more - it's unclear whether it means the return value (in preparation) for the _containing_ function or the return value received from a subroutine call, and occasionally I've accidentally used the same variable for both and introduced a bug. So where one of those got in my way, I've renamed it to 'toret' or 'retd' (the latter short for 'returned') in line with my usual modern practice, but I haven't done a thorough job of finding all of them. Finally, one amusing side effect of doing this is that I've had to separate quite a few chained assignments. It used to be perfectly fine to write 'a = b = c = TRUE' when a,b,c were int and TRUE was just a the 'true' defined by stdbool.h, that idiom provokes a warning from gcc: 'suggest parentheses around assignment used as truth value'!

Stop front ends remembering the data of their last paste. Previously, both the Unix and Windows front ends would respond to a paste action by retrieving data from the system clipboard, converting it appropriately, _storing_ it in a persistent dynamic data block inside the front end, and then calling term_do_paste(term), which in turn would call back to the front end via get_clip() to retrieve the current contents of that stored data block. But, as far as I can tell, this was a completely pointless mechanism, because after a data block was written into this storage area, it would be immediately used for exactly one paste, and then never accessed again until the next paste action caused it to be freed and replaced with a new chunk of pasted data. So why on earth was it stored persistently at all, and why that callback mechanism from frontend to terminal back to frontend to retrieve it for the actual paste action? I have no idea. This change removes the entire system and replaces it with the completely obvious alternative: the character-set-converted version of paste data is allocated in a _local_ variable in the frontend paste functions, passed directly to term_do_paste which now takes (buffer,length) parameters, and freed immediately afterwards. get_clip() is gone.

Stop front ends remembering the data of their last paste. Previously, both the Unix and Windows front ends would respond to a paste action by retrieving data from the system clipboard, converting it appropriately, _storing_ it in a persistent dynamic data block inside the front end, and then calling term_do_paste(term), which in turn would call back to the front end via get_clip() to retrieve the current contents of that stored data block. But, as far as I can tell, this was a completely pointless mechanism, because after a data block was written into this storage area, it would be immediately used for exactly one paste, and then never accessed again until the next paste action caused it to be freed and replaced with a new chunk of pasted data. So why on earth was it stored persistently at all, and why that callback mechanism from frontend to terminal back to frontend to retrieve it for the actual paste action? I have no idea. This change removes the entire system and replaces it with the completely obvious alternative: the character-set-converted version of paste data is allocated in a _local_ variable in the frontend paste functions, passed directly to term_do_paste which now takes (buffer,length) parameters, and freed immediately afterwards. get_clip() is gone.

Remove the 'Frontend' type and replace it with a vtable. After the recent Seat and LogContext revamps, _nearly_ all the remaining uses of the type 'Frontend' were in terminal.c, which needs all sorts of interactions with the GUI window the terminal lives in, from the obvious (actually drawing text on the window, reading and writing the clipboard) to the obscure (minimising, maximising and moving the window in response to particular escape sequences). All of those functions are now provided by an abstraction called TermWin. The few remaining uses of Frontend after _that_ are internal to a particular platform directory, so as to spread the implementation of that particular kind of Frontend between multiple source files; so I've renamed all of those so that they take a more specifically named type that refers to the particular implementation rather than the general abstraction. So now the name 'Frontend' no longer exists in the code base at all, and everywhere one used to be used, it's completely clear whether it was operating in one of Frontend's three abstract roles (and if so, which), or whether it was specific to a particular implementation. Another type that's disappeared is 'Context', which used to be a typedef defined to something different on each platform, describing whatever short-lived resources were necessary to draw on the terminal window: the front end would provide a ready-made one when calling term_paint, and the terminal could request one with get_ctx/free_ctx if it wanted to do proactive window updates. Now that drawing context lives inside the TermWin itself, because there was never any need to have two of those contexts live at the same time. (Another minor API change is that the window-title functions - both reading and writing - have had a missing 'const' added to their char * parameters / return values.) I don't expect this change to enable any particularly interesting new functionality (in particular, I have no plans that need more than one implementation of TermWin in the same application). But it completes the tidying-up that began with the Seat and LogContext rework.

Add a system of clipboard identifiers. This lays some groundwork for making PuTTY's cut and paste handling more flexible in the area of which clipboard(s) it reads and writes, if more than one is available on the system. I've introduced a system of list macros which define an enumeration of integer clipboard ids, some defined centrally in putty.h (at present just a CLIP_NULL which never has any text in it, because that seems like the sort of thing that will come in useful for configuring a given copy or paste UI action to be ignored) and some defined per platform. All the front end functions that copy and paste take a clipboard id, and the Terminal structure is now configured at startup to tell it which clipboard id it should paste from on a mouse click, and which it should copy from on a selection. However, I haven't actually added _real_ support for multiple X11 clipboards, in that the Unix front end supports a single CLIP_SYSTEM regardless of whether it's in OS X or GTK mode. So this is currently a NFC refactoring which does nothing but prepare the way for real changes to come.

GUI PuTTY: stop using the global 'hwnd'. This was the difficult part of cleaning up that global variable. The main Windows PuTTY GUI is split between source files, so that _does_ actually need to refer to the main window from multiple places. But all the places where windlg.c needed to use 'hwnd' are seat methods, so they were already receiving a Seat pointer as a parameter. In other words, the methods of the Windows GUI Seat were already split between source files. So it seems only fair that they should be able to share knowledge of the seat's data as well. Hence, I've created a small 'WinGuiSeat' structure which both window.c and windlg.c can see the layout of, and put the main terminal window handle in there. Then the seat methods implemented in windlg.c, like win_seat_verify_ssh_host_key, can use container_of to turn the Seat pointer parameter back into the address of that structure, just as the methods in window.c can do (even though they currently don't need to). (Who knows: now that it _exists_, perhaps that structure can be gradually expanded in future to turn it into a proper encapsulation of all the Windows frontend's state, like we should have had all along...) I've also moved the Windows GUI LogPolicy implementation into the same object (i.e. WinGuiSeat implements both traits at once). That allows win_gui_logging_error to recover the same WinGuiSeat from its input LogPolicy pointer, which means it can get from there to the Seat facet of the same object, so that I don't need the extern variable 'win_seat' any more either.

Giant const-correctness patch of doom! Having found a lot of unfixed constness issues in recent development, I thought perhaps it was time to get proactive, so I compiled the whole codebase with -Wwrite-strings. That turned up a huge load of const problems, which I've fixed in this commit: the Unix build now goes cleanly through with -Wwrite-strings, and the Windows build is as close as I could get it (there are some lingering issues due to occasional Windows API functions like AcquireCredentialsHandle not having the right constness). Notable fallout beyond the purely mechanical changing of types: - the stuff saved by cmdline_save_param() is now explicitly dupstr()ed, and freed in cmdline_run_saved. - I couldn't make both string arguments to cmdline_process_param() const, because it intentionally writes to one of them in the case where it's the argument to -pw (in the vain hope of being at least slightly friendly to 'ps'), so elsewhere I had to temporarily dupstr() something for the sake of passing it to that function - I had to invent a silly parallel version of const_cmp() so I could pass const string literals in to lookup functions. - stripslashes() in pscp.c and psftp.c has the annoying strchr nature

Convert a lot of 'int' variables to 'bool'. My normal habit these days, in new code, is to treat int and bool as _almost_ completely separate types. I'm still willing to use C's implicit test for zero on an integer (e.g. 'if (!blob.len)' is fine, no need to spell it out as blob.len != 0), but generally, if a variable is going to be conceptually a boolean, I like to declare it bool and assign to it using 'true' or 'false' rather than 0 or 1. PuTTY is an exception, because it predates the C99 bool, and I've stuck to its existing coding style even when adding new code to it. But it's been annoying me more and more, so now that I've decided C99 bool is an acceptable thing to require from our toolchain in the first place, here's a quite thorough trawl through the source doing 'boolification'. Many variables and function parameters are now typed as bool rather than int; many assignments of 0 or 1 to those variables are now spelled 'true' or 'false'. I managed this thorough conversion with the help of a custom clang plugin that I wrote to trawl the AST and apply heuristics to point out where things might want changing. So I've even managed to do a decent job on parts of the code I haven't looked at in years! To make the plugin's work easier, I pushed platform front ends generally in the direction of using standard 'bool' in preference to platform-specific boolean types like Windows BOOL or GTK's gboolean; I've left the platform booleans in places they _have_ to be for the platform APIs to work right, but variables only used by my own code have been converted wherever I found them. In a few places there are int values that look very like booleans in _most_ of the places they're used, but have a rarely-used third value, or a distinction between different nonzero values that most users don't care about. In these cases, I've _removed_ uses of 'true' and 'false' for the return values, to emphasise that there's something more subtle going on than a simple boolean answer: - the 'multisel' field in dialog.h's list box structure, for which the GTK front end in particular recognises a difference between 1 and 2 but nearly everything else treats as boolean - the 'urgent' parameter to plug_receive, where 1 vs 2 tells you something about the specific location of the urgent pointer, but most clients only care about 0 vs 'something nonzero' - the return value of wc_match, where -1 indicates a syntax error in the wildcard. - the return values from SSH-1 RSA-key loading functions, which use -1 for 'wrong passphrase' and 0 for all other failures (so any caller which already knows it's not loading an _encrypted private_ key can treat them as boolean) - term->esc_query, and the 'query' parameter in toggle_mode in terminal.c, which _usually_ hold 0 for ESC[123h or 1 for ESC[?123h, but can also hold -1 for some other intervening character that we don't support. In a few places there's an integer that I haven't turned into a bool even though it really _can_ only take values 0 or 1 (and, as above, tried to make the call sites consistent in not calling those values true and false), on the grounds that I thought it would make it more confusing to imply that the 0 value was in some sense 'negative' or bad and the 1 positive or good: - the return value of plug_accepting uses the POSIXish convention of 0=success and nonzero=error; I think if I made it bool then I'd also want to reverse its sense, and that's a job for a separate piece of work. - the 'screen' parameter to lineptr() in terminal.c, where 0 and 1 represent the default and alternate screens. There's no obvious reason why one of those should be considered 'true' or 'positive' or 'success' - they're just indices - so I've left it as int. ssh_scp_recv had particularly confusing semantics for its previous int return value: its call sites used '<= 0' to check for error, but it never actually returned a negative number, just 0 or 1. Now the function and its call sites agree that it's a bool. In a couple of places I've renamed variables called 'ret', because I don't like that name any more - it's unclear whether it means the return value (in preparation) for the _containing_ function or the return value received from a subroutine call, and occasionally I've accidentally used the same variable for both and introduced a bug. So where one of those got in my way, I've renamed it to 'toret' or 'retd' (the latter short for 'returned') in line with my usual modern practice, but I haven't done a thorough job of finding all of them. Finally, one amusing side effect of doing this is that I've had to separate quite a few chained assignments. It used to be perfectly fine to write 'a = b = c = TRUE' when a,b,c were int and TRUE was just a the 'true' defined by stdbool.h, that idiom provokes a warning from gcc: 'suggest parentheses around assignment used as truth value'!

GUI PuTTY: stop using the global 'hwnd'. This was the difficult part of cleaning up that global variable. The main Windows PuTTY GUI is split between source files, so that _does_ actually need to refer to the main window from multiple places. But all the places where windlg.c needed to use 'hwnd' are seat methods, so they were already receiving a Seat pointer as a parameter. In other words, the methods of the Windows GUI Seat were already split between source files. So it seems only fair that they should be able to share knowledge of the seat's data as well. Hence, I've created a small 'WinGuiSeat' structure which both window.c and windlg.c can see the layout of, and put the main terminal window handle in there. Then the seat methods implemented in windlg.c, like win_seat_verify_ssh_host_key, can use container_of to turn the Seat pointer parameter back into the address of that structure, just as the methods in window.c can do (even though they currently don't need to). (Who knows: now that it _exists_, perhaps that structure can be gradually expanded in future to turn it into a proper encapsulation of all the Windows frontend's state, like we should have had all along...) I've also moved the Windows GUI LogPolicy implementation into the same object (i.e. WinGuiSeat implements both traits at once). That allows win_gui_logging_error to recover the same WinGuiSeat from its input LogPolicy pointer, which means it can get from there to the Seat facet of the same object, so that I don't need the extern variable 'win_seat' any more either.

Convert a lot of 'int' variables to 'bool'. My normal habit these days, in new code, is to treat int and bool as _almost_ completely separate types. I'm still willing to use C's implicit test for zero on an integer (e.g. 'if (!blob.len)' is fine, no need to spell it out as blob.len != 0), but generally, if a variable is going to be conceptually a boolean, I like to declare it bool and assign to it using 'true' or 'false' rather than 0 or 1. PuTTY is an exception, because it predates the C99 bool, and I've stuck to its existing coding style even when adding new code to it. But it's been annoying me more and more, so now that I've decided C99 bool is an acceptable thing to require from our toolchain in the first place, here's a quite thorough trawl through the source doing 'boolification'. Many variables and function parameters are now typed as bool rather than int; many assignments of 0 or 1 to those variables are now spelled 'true' or 'false'. I managed this thorough conversion with the help of a custom clang plugin that I wrote to trawl the AST and apply heuristics to point out where things might want changing. So I've even managed to do a decent job on parts of the code I haven't looked at in years! To make the plugin's work easier, I pushed platform front ends generally in the direction of using standard 'bool' in preference to platform-specific boolean types like Windows BOOL or GTK's gboolean; I've left the platform booleans in places they _have_ to be for the platform APIs to work right, but variables only used by my own code have been converted wherever I found them. In a few places there are int values that look very like booleans in _most_ of the places they're used, but have a rarely-used third value, or a distinction between different nonzero values that most users don't care about. In these cases, I've _removed_ uses of 'true' and 'false' for the return values, to emphasise that there's something more subtle going on than a simple boolean answer: - the 'multisel' field in dialog.h's list box structure, for which the GTK front end in particular recognises a difference between 1 and 2 but nearly everything else treats as boolean - the 'urgent' parameter to plug_receive, where 1 vs 2 tells you something about the specific location of the urgent pointer, but most clients only care about 0 vs 'something nonzero' - the return value of wc_match, where -1 indicates a syntax error in the wildcard. - the return values from SSH-1 RSA-key loading functions, which use -1 for 'wrong passphrase' and 0 for all other failures (so any caller which already knows it's not loading an _encrypted private_ key can treat them as boolean) - term->esc_query, and the 'query' parameter in toggle_mode in terminal.c, which _usually_ hold 0 for ESC[123h or 1 for ESC[?123h, but can also hold -1 for some other intervening character that we don't support.

Two related changes to timing code: First, make absolute times unsigned. This means that it's safe to depend on their overflow behaviour (which is undefined for signed integers). This requires a little extra care in handling comparisons, but I think I've correctly adjusted them all. Second, functions registered with schedule_timer() are guaranteed to be called with precisely the time that was returned by schedule_timer(). Thus, it's only necessary to check these values for equality rather than doing risky range checks, so do that. The timing code still does lots that's undefined, unnecessary, or just wrong, but this is a good start. [originally from svn r9667]

Post-release destabilisation! Completely remove the struct type 'Config' in putty.h, which stores all PuTTY's settings and includes an arbitrary length limit on every single one of those settings which is stored in string form. In place of it is 'Conf', an opaque data type everywhere outside the new file conf.c, which stores a list of (key, value) pairs in which every key contains an integer identifying a configuration setting, and for some of those integers the key also contains extra parts (so that, for instance, CONF_environmt is a string-to-string mapping). Everywhere that a Config was previously used, a Conf is now; everywhere there was a Config structure copy, conf_copy() is called; every lookup, adjustment, load and save operation on a Config has been rewritten; and there's a mechanism for serialising a Conf into a binary blob and back for use with Duplicate Session. User-visible effects of this change _should_ be minimal, though I don't doubt I've introduced one or two bugs here and there which will eventually be found. The _intended_ visible effects of this change are that all arbitrary limits on configuration strings and lists (e.g. limit on number of port forwardings) should now disappear; that list boxes in the configuration will now be displayed in a sorted order rather than the arbitrary order in which they were added to the list (since the underlying data structure is now a sorted tree234 rather than an ad-hoc comma-separated string); and one more specific change, which is that local and dynamic port forwardings on the same port number are now mutually exclusive in the configuration (putting 'D' in the key rather than the value was a mistake in the first place). One other reorganisation as a result of this is that I've moved all the dialog.c standard handlers (dlg_stdeditbox_handler and friends) out into config.c, because I can't really justify calling them generic any more. When they took a pointer to an arbitrary structure type and the offset of a field within that structure, they were independent of whether that structure was a Config or something completely different, but now they really do expect to talk to a Conf, which can _only_ be used for PuTTY configuration, so I've renamed them all things like conf_editbox_handler and moved them out of the nominally independent dialog-box management module into the PuTTY-specific config.c.

The _intended_ visible effects of this change are that all arbitrary limits on configuration strings and lists (e.g. limit on number of port forwardings) should now disappear; that list boxes in the configuration will now be displayed in a sorted order rather than the arbitrary order in which they were added to the list (since the underlying data structure is now a sorted tree234 rather than an ad-hoc comma-separated string); and one more specific change, which is that local and dynamic port forwardings on the same port number are now mutually exclusive in the configuration (putting 'D' in the key rather than the value was a mistake in the first place). One other reorganisation as a result of this is that I've moved all the dialog.c standard handlers (dlg_stdeditbox_handler and friends) out into config.c, because I can't really justify calling them generic any more. When they took a pointer to an arbitrary structure type and the offset of a field within that structure, they were independent of whether that structure was a Config or something completely different, but now they really do expect to talk to a Conf, which can _only_ be used for PuTTY configuration, so I've renamed them all things like conf_editbox_handler and moved them out of the nominally independent dialog-box management module into the PuTTY-specific config.c.

Remove the 'Frontend' type and replace it with a vtable. After the recent Seat and LogContext revamps, _nearly_ all the remaining uses of the type 'Frontend' were in terminal.c, which needs all sorts of interactions with the GUI window the terminal lives in, from the obvious (actually drawing text on the window, reading and writing the clipboard) to the obscure (minimising, maximising and moving the window in response to particular escape sequences). All of those functions are now provided by an abstraction called TermWin. The few remaining uses of Frontend after _that_ are internal to a particular platform directory, so as to spread the implementation of that particular kind of Frontend between multiple source files; so I've renamed all of those so that they take a more specifically named type that refers to the particular implementation rather than the general abstraction. So now the name 'Frontend' no longer exists in the code base at all, and everywhere one used to be used, it's completely clear whether it was operating in one of Frontend's three abstract roles (and if so, which), or whether it was specific to a particular implementation. Another type that's disappeared is 'Context', which used to be a typedef defined to something different on each platform, describing whatever short-lived resources were necessary to draw on the terminal window: the front end would provide a ready-made one when calling term_paint, and the terminal could request one with get_ctx/free_ctx if it wanted to do proactive window updates. Now that drawing context lives inside the TermWin itself, because there was never any need to have two of those contexts live at the same time. (Another minor API change is that the window-title functions - both reading and writing - have had a missing 'const' added to their char * parameters / return values.) I don't expect this change to enable any particularly interesting new functionality (in particular, I have no plans that need more than one implementation of TermWin in the same application). But it completes the tidying-up that began with the Seat and LogContext rework.

Major destabilisation, phase 1. In this phase I've moved (I think) all the global and function-static variables out of terminal.c into a dynamically allocated data structure. Note that this does not yet confer the ability to run more than one of them in the same process, because other things (the line discipline, the back end) are still global, and also in particular the address of the dynamically allocated terminal-data structure is held in a global variable `term'. But what I've got here represents a reasonable stopping point at which to check things in. In _theory_ this should all still work happily, on both Unix and Windows. In practice, who knows?

Convert a lot of 'int' variables to 'bool'. My normal habit these days, in new code, is to treat int and bool as _almost_ completely separate types. I'm still willing to use C's implicit test for zero on an integer (e.g. 'if (!blob.len)' is fine, no need to spell it out as blob.len != 0), but generally, if a variable is going to be conceptually a boolean, I like to declare it bool and assign to it using 'true' or 'false' rather than 0 or 1. PuTTY is an exception, because it predates the C99 bool, and I've stuck to its existing coding style even when adding new code to it. But it's been annoying me more and more, so now that I've decided C99 bool is an acceptable thing to require from our toolchain in the first place, here's a quite thorough trawl through the source doing 'boolification'. Many variables and function parameters are now typed as bool rather than int; many assignments of 0 or 1 to those variables are now spelled 'true' or 'false'. I managed this thorough conversion with the help of a custom clang plugin that I wrote to trawl the AST and apply heuristics to point out where things might want changing. So I've even managed to do a decent job on parts of the code I haven't looked at in years! To make the plugin's work easier, I pushed platform front ends generally in the direction of using standard 'bool' in preference to platform-specific boolean types like Windows BOOL or GTK's gboolean; I've left the platform booleans in places they _have_ to be for the platform APIs to work right, but variables only used by my own code have been converted wherever I found them. In a few places there are int values that look very like booleans in _most_ of the places they're used, but have a rarely-used third value, or a distinction between different nonzero values that most users don't care about. In these cases, I've _removed_ uses of 'true' and 'false' for the return values, to emphasise that there's something more subtle going on than a simple boolean answer: - the 'multisel' field in dialog.h's list box structure, for which the GTK front end in particular recognises a difference between 1 and 2 but nearly everything else treats as boolean - the 'urgent' parameter to plug_receive, where 1 vs 2 tells you something about the specific location of the urgent pointer, but most clients only care about 0 vs 'something nonzero' - the return value of wc_match, where -1 indicates a syntax error in the wildcard. - the return values from SSH-1 RSA-key loading functions, which use -1 for 'wrong passphrase' and 0 for all other failures (so any caller which already knows it's not loading an _encrypted private_ key can treat them as boolean) - term->esc_query, and the 'query' parameter in toggle_mode in terminal.c, which _usually_ hold 0 for ESC[123h or 1 for ESC[?123h, but can also hold -1 for some other intervening character that we don't support. In a few places there's an integer that I haven't turned into a bool even though it really _can_ only take values 0 or 1 (and, as above, tried to make the call sites consistent in not calling those values true and false), on the grounds that I thought it would make it more confusing to imply that the 0 value was in some sense 'negative' or bad and the 1 positive or good: - the return value of plug_accepting uses the POSIXish convention of 0=success and nonzero=error; I think if I made it bool then I'd also want to reverse its sense, and that's a job for a separate piece of work. - the 'screen' parameter to lineptr() in terminal.c, where 0 and 1 represent the default and alternate screens. There's no obvious reason why one of those should be considered 'true' or 'positive' or 'success' - they're just indices - so I've left it as int. ssh_scp_recv had particularly confusing semantics for its previous int return value: its call sites used '<= 0' to check for error, but it never actually returned a negative number, just 0 or 1. Now the function and its call sites agree that it's a bool. In a couple of places I've renamed variables called 'ret', because I don't like that name any more - it's unclear whether it means the return value (in preparation) for the _containing_ function or the return value received from a subroutine call, and occasionally I've accidentally used the same variable for both and introduced a bug. So where one of those got in my way, I've renamed it to 'toret' or 'retd' (the latter short for 'returned') in line with my usual modern practice, but I haven't done a thorough job of finding all of them. Finally, one amusing side effect of doing this is that I've had to separate quite a few chained assignments. It used to be perfectly fine to write 'a = b = c = TRUE' when a,b,c were int and TRUE was just a the 'true' defined by stdbool.h, that idiom provokes a warning from gcc: 'suggest parentheses around assignment used as truth value'!

GUI PuTTY: stop using the global 'hwnd'. This was the difficult part of cleaning up that global variable. The main Windows PuTTY GUI is split between source files, so that _does_ actually need to refer to the main window from multiple places. But all the places where windlg.c needed to use 'hwnd' are seat methods, so they were already receiving a Seat pointer as a parameter. In other words, the methods of the Windows GUI Seat were already split between source files. So it seems only fair that they should be able to share knowledge of the seat's data as well. Hence, I've created a small 'WinGuiSeat' structure which both window.c and windlg.c can see the layout of, and put the main terminal window handle in there. Then the seat methods implemented in windlg.c, like win_seat_verify_ssh_host_key, can use container_of to turn the Seat pointer parameter back into the address of that structure, just as the methods in window.c can do (even though they currently don't need to). (Who knows: now that it _exists_, perhaps that structure can be gradually expanded in future to turn it into a proper encapsulation of all the Windows frontend's state, like we should have had all along...) I've also moved the Windows GUI LogPolicy implementation into the same object (i.e. WinGuiSeat implements both traits at once). That allows win_gui_logging_error to recover the same WinGuiSeat from its input LogPolicy pointer, which means it can get from there to the Seat facet of the same object, so that I don't need the extern variable 'win_seat' any more either.

Remove the 'Frontend' type and replace it with a vtable. After the recent Seat and LogContext revamps, _nearly_ all the remaining uses of the type 'Frontend' were in terminal.c, which needs all sorts of interactions with the GUI window the terminal lives in, from the obvious (actually drawing text on the window, reading and writing the clipboard) to the obscure (minimising, maximising and moving the window in response to particular escape sequences). All of those functions are now provided by an abstraction called TermWin. The few remaining uses of Frontend after _that_ are internal to a particular platform directory, so as to spread the implementation of that particular kind of Frontend between multiple source files; so I've renamed all of those so that they take a more specifically named type that refers to the particular implementation rather than the general abstraction. So now the name 'Frontend' no longer exists in the code base at all, and everywhere one used to be used, it's completely clear whether it was operating in one of Frontend's three abstract roles (and if so, which), or whether it was specific to a particular implementation. Another type that's disappeared is 'Context', which used to be a typedef defined to something different on each platform, describing whatever short-lived resources were necessary to draw on the terminal window: the front end would provide a ready-made one when calling term_paint, and the terminal could request one with get_ctx/free_ctx if it wanted to do proactive window updates. Now that drawing context lives inside the TermWin itself, because there was never any need to have two of those contexts live at the same time. (Another minor API change is that the window-title functions - both reading and writing - have had a missing 'const' added to their char * parameters / return values.) I don't expect this change to enable any particularly interesting new functionality (in particular, I have no plans that need more than one implementation of TermWin in the same application). But it completes the tidying-up that began with the Seat and LogContext rework.

Post-release destabilisation! Completely remove the struct type 'Config' in putty.h, which stores all PuTTY's settings and includes an arbitrary length limit on every single one of those settings which is stored in string form. In place of it is 'Conf', an opaque data type everywhere outside the new file conf.c, which stores a list of (key, value) pairs in which every key contains an integer identifying a configuration setting, and for some of those integers the key also contains extra parts (so that, for instance, CONF_environmt is a string-to-string mapping). Everywhere that a Config was previously used, a Conf is now; everywhere there was a Config structure copy, conf_copy() is called; every lookup, adjustment, load and save operation on a Config has been rewritten; and there's a mechanism for serialising a Conf into a binary blob and back for use with Duplicate Session. User-visible effects of this change _should_ be minimal, though I don't doubt I've introduced one or two bugs here and there which will eventually be found. The _intended_ visible effects of this change are that all arbitrary limits on configuration strings and lists (e.g. limit on number of port forwardings) should now disappear; that list boxes in the configuration will now be displayed in a sorted order rather than the arbitrary order in which they were added to the list (since the underlying data structure is now a sorted tree234 rather than an ad-hoc comma-separated string); and one more specific change, which is that local and dynamic port forwardings on the same port number are now mutually exclusive in the configuration (putting 'D' in the key rather than the value was a mistake in the first place). One other reorganisation as a result of this is that I've moved all the dialog.c standard handlers (dlg_stdeditbox_handler and friends) out into config.c, because I can't really justify calling them generic any more. When they took a pointer to an arbitrary structure type and the offset of a field within that structure, they were independent of whether that structure was a Config or something completely different, but now they really do expect to talk to a Conf, which can _only_ be used for PuTTY configuration, so I've renamed them all things like conf_editbox_handler and moved them out of the nominally independent dialog-box management module into the PuTTY-specific config.c.

Convert a lot of 'int' variables to 'bool'. My normal habit these days, in new code, is to treat int and bool as _almost_ completely separate types. I'm still willing to use C's implicit test for zero on an integer (e.g. 'if (!blob.len)' is fine, no need to spell it out as blob.len != 0), but generally, if a variable is going to be conceptually a boolean, I like to declare it bool and assign to it using 'true' or 'false' rather than 0 or 1. PuTTY is an exception, because it predates the C99 bool, and I've stuck to its existing coding style even when adding new code to it. But it's been annoying me more and more, so now that I've decided C99 bool is an acceptable thing to require from our toolchain in the first place, here's a quite thorough trawl through the source doing 'boolification'. Many variables and function parameters are now typed as bool rather than int; many assignments of 0 or 1 to those variables are now spelled 'true' or 'false'. I managed this thorough conversion with the help of a custom clang plugin that I wrote to trawl the AST and apply heuristics to point out where things might want changing. So I've even managed to do a decent job on parts of the code I haven't looked at in years! To make the plugin's work easier, I pushed platform front ends generally in the direction of using standard 'bool' in preference to platform-specific boolean types like Windows BOOL or GTK's gboolean; I've left the platform booleans in places they _have_ to be for the platform APIs to work right, but variables only used by my own code have been converted wherever I found them. In a few places there are int values that look very like booleans in _most_ of the places they're used, but have a rarely-used third value, or a distinction between different nonzero values that most users don't care about. In these cases, I've _removed_ uses of 'true' and 'false' for the return values, to emphasise that there's something more subtle going on than a simple boolean answer: - the 'multisel' field in dialog.h's list box structure, for which the GTK front end in particular recognises a difference between 1 and 2 but nearly everything else treats as boolean - the 'urgent' parameter to plug_receive, where 1 vs 2 tells you something about the specific location of the urgent pointer, but most clients only care about 0 vs 'something nonzero' - the return value of wc_match, where -1 indicates a syntax error in the wildcard. - the return values from SSH-1 RSA-key loading functions, which use -1 for 'wrong passphrase' and 0 for all other failures (so any caller which already knows it's not loading an _encrypted private_ key can treat them as boolean) - term->esc_query, and the 'query' parameter in toggle_mode in terminal.c, which _usually_ hold 0 for ESC[123h or 1 for ESC[?123h, but can also hold -1 for some other intervening character that we don't support. In a few places there's an integer that I haven't turned into a bool even though it really _can_ only take values 0 or 1 (and, as above, tried to make the call sites consistent in not calling those values true and false), on the grounds that I thought it would make it more confusing to imply that the 0 value was in some sense 'negative' or bad and the 1 positive or good: - the return value of plug_accepting uses the POSIXish convention of 0=success and nonzero=error; I think if I made it bool then I'd also want to reverse its sense, and that's a job for a separate piece of work. - the 'screen' parameter to lineptr() in terminal.c, where 0 and 1 represent the default and alternate screens. There's no obvious reason why one of those should be considered 'true' or 'positive' or 'success' - they're just indices - so I've left it as int. ssh_scp_recv had particularly confusing semantics for its previous int return value: its call sites used '<= 0' to check for error, but it never actually returned a negative number, just 0 or 1. Now the function and its call sites agree that it's a bool. In a couple of places I've renamed variables called 'ret', because I don't like that name any more - it's unclear whether it means the return value (in preparation) for the _containing_ function or the return value received from a subroutine call, and occasionally I've accidentally used the same variable for both and introduced a bug. So where one of those got in my way, I've renamed it to 'toret' or 'retd' (the latter short for 'returned') in line with my usual modern practice, but I haven't done a thorough job of finding all of them. Finally, one amusing side effect of doing this is that I've had to separate quite a few chained assignments. It used to be perfectly fine to write 'a = b = c = TRUE' when a,b,c were int and TRUE was just a the 'true' defined by stdbool.h, that idiom provokes a warning from gcc: 'suggest parentheses around assignment used as truth value'!

Switch some Conf settings over to being bool. I think this is the full set of things that ought logically to be boolean. One annoyance is that quite a few radio-button controls in config.c address Conf fields that are now bool rather than int, which means that the shared handler function can't just access them all with conf_{get,set}_int. Rather than back out the rigorous separation of int and bool in conf.c itself, I've just added a similar alternative handler function for the bool-typed ones.

Convert a lot of 'int' variables to 'bool'. My normal habit these days, in new code, is to treat int and bool as _almost_ completely separate types. I'm still willing to use C's implicit test for zero on an integer (e.g. 'if (!blob.len)' is fine, no need to spell it out as blob.len != 0), but generally, if a variable is going to be conceptually a boolean, I like to declare it bool and assign to it using 'true' or 'false' rather than 0 or 1. PuTTY is an exception, because it predates the C99 bool, and I've stuck to its existing coding style even when adding new code to it. But it's been annoying me more and more, so now that I've decided C99 bool is an acceptable thing to require from our toolchain in the first place, here's a quite thorough trawl through the source doing 'boolification'. Many variables and function parameters are now typed as bool rather than int; many assignments of 0 or 1 to those variables are now spelled 'true' or 'false'. I managed this thorough conversion with the help of a custom clang plugin that I wrote to trawl the AST and apply heuristics to point out where things might want changing. So I've even managed to do a decent job on parts of the code I haven't looked at in years! To make the plugin's work easier, I pushed platform front ends generally in the direction of using standard 'bool' in preference to platform-specific boolean types like Windows BOOL or GTK's gboolean; I've left the platform booleans in places they _have_ to be for the platform APIs to work right, but variables only used by my own code have been converted wherever I found them. In a few places there are int values that look very like booleans in _most_ of the places they're used, but have a rarely-used third value, or a distinction between different nonzero values that most users don't care about. In these cases, I've _removed_ uses of 'true' and 'false' for the return values, to emphasise that there's something more subtle going on than a simple boolean answer: - the 'multisel' field in dialog.h's list box structure, for which the GTK front end in particular recognises a difference between 1 and 2 but nearly everything else treats as boolean - the 'urgent' parameter to plug_receive, where 1 vs 2 tells you something about the specific location of the urgent pointer, but most clients only care about 0 vs 'something nonzero' - the return value of wc_match, where -1 indicates a syntax error in the wildcard. - the return values from SSH-1 RSA-key loading functions, which use -1 for 'wrong passphrase' and 0 for all other failures (so any caller which already knows it's not loading an _encrypted private_ key can treat them as boolean) - term->esc_query, and the 'query' parameter in toggle_mode in terminal.c, which _usually_ hold 0 for ESC[123h or 1 for ESC[?123h, but can also hold -1 for some other intervening character that we don't support. In a few places there's an integer that I haven't turned into a bool even though it really _can_ only take values 0 or 1 (and, as above, tried to make the call sites consistent in not calling those values true and false), on the grounds that I thought it would make it more confusing to imply that the 0 value was in some sense 'negative' or bad and the 1 positive or good: - the return value of plug_accepting uses the POSIXish convention of 0=success and nonzero=error; I think if I made it bool then I'd also want to reverse its sense, and that's a job for a separate piece of work. - the 'screen' parameter to lineptr() in terminal.c, where 0 and 1 represent the default and alternate screens. There's no obvious reason why one of those should be considered 'true' or 'positive' or 'success' - they're just indices - so I've left it as int. ssh_scp_recv had particularly confusing semantics for its previous int return value: its call sites used '<= 0' to check for error, but it never actually returned a negative number, just 0 or 1. Now the function and its call sites agree that it's a bool. In a couple of places I've renamed variables called 'ret', because I don't like that name any more - it's unclear whether it means the return value (in preparation) for the _containing_ function or the return value received from a subroutine call, and occasionally I've accidentally used the same variable for both and introduced a bug. So where one of those got in my way, I've renamed it to 'toret' or 'retd' (the latter short for 'returned') in line with my usual modern practice, but I haven't done a thorough job of finding all of them. Finally, one amusing side effect of doing this is that I've had to separate quite a few chained assignments. It used to be perfectly fine to write 'a = b = c = TRUE' when a,b,c were int and TRUE was just a the 'true' defined by stdbool.h, that idiom provokes a warning from gcc: 'suggest parentheses around assignment used as truth value'!

GUI PuTTY: stop using the global 'hwnd'. This was the difficult part of cleaning up that global variable. The main Windows PuTTY GUI is split between source files, so that _does_ actually need to refer to the main window from multiple places. But all the places where windlg.c needed to use 'hwnd' are seat methods, so they were already receiving a Seat pointer as a parameter. In other words, the methods of the Windows GUI Seat were already split between source files. So it seems only fair that they should be able to share knowledge of the seat's data as well. Hence, I've created a small 'WinGuiSeat' structure which both window.c and windlg.c can see the layout of, and put the main terminal window handle in there. Then the seat methods implemented in windlg.c, like win_seat_verify_ssh_host_key, can use container_of to turn the Seat pointer parameter back into the address of that structure, just as the methods in window.c can do (even though they currently don't need to). (Who knows: now that it _exists_, perhaps that structure can be gradually expanded in future to turn it into a proper encapsulation of all the Windows frontend's state, like we should have had all along...) I've also moved the Windows GUI LogPolicy implementation into the same object (i.e. WinGuiSeat implements both traits at once). That allows win_gui_logging_error to recover the same WinGuiSeat from its input LogPolicy pointer, which means it can get from there to the Seat facet of the same object, so that I don't need the extern variable 'win_seat' any more either.

Remove the 'Frontend' type and replace it with a vtable. After the recent Seat and LogContext revamps, _nearly_ all the remaining uses of the type 'Frontend' were in terminal.c, which needs all sorts of interactions with the GUI window the terminal lives in, from the obvious (actually drawing text on the window, reading and writing the clipboard) to the obscure (minimising, maximising and moving the window in response to particular escape sequences). All of those functions are now provided by an abstraction called TermWin. The few remaining uses of Frontend after _that_ are internal to a particular platform directory, so as to spread the implementation of that particular kind of Frontend between multiple source files; so I've renamed all of those so that they take a more specifically named type that refers to the particular implementation rather than the general abstraction. So now the name 'Frontend' no longer exists in the code base at all, and everywhere one used to be used, it's completely clear whether it was operating in one of Frontend's three abstract roles (and if so, which), or whether it was specific to a particular implementation. Another type that's disappeared is 'Context', which used to be a typedef defined to something different on each platform, describing whatever short-lived resources were necessary to draw on the terminal window: the front end would provide a ready-made one when calling term_paint, and the terminal could request one with get_ctx/free_ctx if it wanted to do proactive window updates. Now that drawing context lives inside the TermWin itself, because there was never any need to have two of those contexts live at the same time. (Another minor API change is that the window-title functions - both reading and writing - have had a missing 'const' added to their char * parameters / return values.) I don't expect this change to enable any particularly interesting new functionality (in particular, I have no plans that need more than one implementation of TermWin in the same application). But it completes the tidying-up that began with the Seat and LogContext rework.

It used to be perfectly fine to write 'a = b = c = TRUE' when a,b,c were int and TRUE was just a the 'true' defined by stdbool.h, that idiom provokes a warning from gcc: 'suggest parentheses around assignment used as truth value'!

So I've been wondering for ages about just fixing it, and switching to a spaces-only policy throughout the code. And I recently found out about 'git blame -w', which should make this change not too disruptive for the purposes of source-control archaeology; so perhaps now is the time.

GUI PuTTY: stop using the global 'hwnd'. This was the difficult part of cleaning up that global variable. The main Windows PuTTY GUI is split between source files, so that _does_ actually need to refer to the main window from multiple places. But all the places where windlg.c needed to use 'hwnd' are seat methods, so they were already receiving a Seat pointer as a parameter. In other words, the methods of the Windows GUI Seat were already split between source files. So it seems only fair that they should be able to share knowledge of the seat's data as well. Hence, I've created a small 'WinGuiSeat' structure which both window.c and windlg.c can see the layout of, and put the main terminal window handle in there. Then the seat methods implemented in windlg.c, like win_seat_verify_ssh_host_key, can use container_of to turn the Seat pointer parameter back into the address of that structure, just as the methods in window.c can do (even though they currently don't need to). (Who knows: now that it _exists_, perhaps that structure can be gradually expanded in future to turn it into a proper encapsulation of all the Windows frontend's state, like we should have had all along...) I've also moved the Windows GUI LogPolicy implementation into the same object (i.e. WinGuiSeat implements both traits at once). That allows win_gui_logging_error to recover the same WinGuiSeat from its input LogPolicy pointer, which means it can get from there to the Seat facet of the same object, so that I don't need the extern variable 'win_seat' any more either.

Switch some Conf settings over to being bool. I think this is the full set of things that ought logically to be boolean. One annoyance is that quite a few radio-button controls in config.c address Conf fields that are now bool rather than int, which means that the shared handler function can't just access them all with conf_{get,set}_int. Rather than back out the rigorous separation of int and bool in conf.c itself, I've just added a similar alternative handler function for the bool-typed ones.

Post-release destabilisation! Completely remove the struct type 'Config' in putty.h, which stores all PuTTY's settings and includes an arbitrary length limit on every single one of those settings which is stored in string form. In place of it is 'Conf', an opaque data type everywhere outside the new file conf.c, which stores a list of (key, value) pairs in which every key contains an integer identifying a configuration setting, and for some of those integers the key also contains extra parts (so that, for instance, CONF_environmt is a string-to-string mapping). Everywhere that a Config was previously used, a Conf is now; everywhere there was a Config structure copy, conf_copy() is called; every lookup, adjustment, load and save operation on a Config has been rewritten; and there's a mechanism for serialising a Conf into a binary blob and back for use with Duplicate Session. User-visible effects of this change _should_ be minimal, though I don't doubt I've introduced one or two bugs here and there which will eventually be found. The _intended_ visible effects of this change are that all arbitrary limits on configuration strings and lists (e.g. limit on number of port forwardings) should now disappear; that list boxes in the configuration will now be displayed in a sorted order rather than the arbitrary order in which they were added to the list (since the underlying data structure is now a sorted tree234 rather than an ad-hoc comma-separated string); and one more specific change, which is that local and dynamic port forwardings on the same port number are now mutually exclusive in the configuration (putting 'D' in the key rather than the value was a mistake in the first place). One other reorganisation as a result of this is that I've moved all the dialog.c standard handlers (dlg_stdeditbox_handler and friends) out into config.c, because I can't really justify calling them generic any more. When they took a pointer to an arbitrary structure type and the offset of a field within that structure, they were independent of whether that structure was a Config or something completely different, but now they really do expect to talk to a Conf, which can _only_ be used for PuTTY configuration, so I've renamed them all things like conf_editbox_handler and moved them out of the nominally independent dialog-box management module into the PuTTY-specific config.c.

Switch some Conf settings over to being bool. I think this is the full set of things that ought logically to be boolean. One annoyance is that quite a few radio-button controls in config.c address Conf fields that are now bool rather than int, which means that the shared handler function can't just access them all with conf_{get,set}_int. Rather than back out the rigorous separation of int and bool in conf.c itself, I've just added a similar alternative handler function for the bool-typed ones.

GUI PuTTY: stop using the global 'hwnd'. This was the difficult part of cleaning up that global variable. The main Windows PuTTY GUI is split between source files, so that _does_ actually need to refer to the main window from multiple places. But all the places where windlg.c needed to use 'hwnd' are seat methods, so they were already receiving a Seat pointer as a parameter. In other words, the methods of the Windows GUI Seat were already split between source files. So it seems only fair that they should be able to share knowledge of the seat's data as well. Hence, I've created a small 'WinGuiSeat' structure which both window.c and windlg.c can see the layout of, and put the main terminal window handle in there. Then the seat methods implemented in windlg.c, like win_seat_verify_ssh_host_key, can use container_of to turn the Seat pointer parameter back into the address of that structure, just as the methods in window.c can do (even though they currently don't need to). (Who knows: now that it _exists_, perhaps that structure can be gradually expanded in future to turn it into a proper encapsulation of all the Windows frontend's state, like we should have had all along...) I've also moved the Windows GUI LogPolicy implementation into the same object (i.e. WinGuiSeat implements both traits at once). That allows win_gui_logging_error to recover the same WinGuiSeat from its input LogPolicy pointer, which means it can get from there to the Seat facet of the same object, so that I don't need the extern variable 'win_seat' any more either.

static size_t win_seat_output(Seat *seat, bool is_stderr,
const void *data, size_t len)
Rationalisation of the system of frontend handles. Most modular bits of PuTTY (terminal, backend, logctx etc) take a `void *' handle passed to them from the frontend, and used as a context for all their callbacks. Most of these point at the frontend structure itself (on platforms where this is meaningful), except that the handle passed to the backend has always pointed at the terminal because from_backend() was implemented in terminal.c. This has finally bitten Unix PuTTY, because both backend and logctx have been passing their respective and very different frontend handles to logevent(), so I've fixed it. from_backend() is now a function supplied by the _frontend_ itself, in all cases, and the frontend handle passed to backends must be the same as that passed to everything else. What was from_backend() in terminal.c is now called term_data(), and the typical implementation of from_backend() in a GUI frontend will just extract the terminal handle from the frontend structure and delegate to that. This appears to work on Unix and Windows, but has most likely broken the Mac build. [originally from svn r3100]

Convert a lot of 'int' variables to 'bool'. My normal habit these days, in new code, is to treat int and bool as _almost_ completely separate types. I'm still willing to use C's implicit test for zero on an integer (e.g. 'if (!blob.len)' is fine, no need to spell it out as blob.len != 0), but generally, if a variable is going to be conceptually a boolean, I like to declare it bool and assign to it using 'true' or 'false' rather than 0 or 1. PuTTY is an exception, because it predates the C99 bool, and I've stuck to its existing coding style even when adding new code to it. But it's been annoying me more and more, so now that I've decided C99 bool is an acceptable thing to require from our toolchain in the first place, here's a quite thorough trawl through the source doing 'boolification'. Many variables and function parameters are now typed as bool rather than int; many assignments of 0 or 1 to those variables are now spelled 'true' or 'false'. I managed this thorough conversion with the help of a custom clang plugin that I wrote to trawl the AST and apply heuristics to point out where things might want changing. So I've even managed to do a decent job on parts of the code I haven't looked at in years! To make the plugin's work easier, I pushed platform front ends generally in the direction of using standard 'bool' in preference to platform-specific boolean types like Windows BOOL or GTK's gboolean; I've left the platform booleans in places they _have_ to be for the platform APIs to work right, but variables only used by my own code have been converted wherever I found them. In a few places there are int values that look very like booleans in _most_ of the places they're used, but have a rarely-used third value, or a distinction between different nonzero values that most users don't care about. In these cases, I've _removed_ uses of 'true' and 'false' for the return values, to emphasise that there's something more subtle going on than a simple boolean answer: - the 'multisel' field in dialog.h's list box structure, for which the GTK front end in particular recognises a difference between 1 and 2 but nearly everything else treats as boolean - the 'urgent' parameter to plug_receive, where 1 vs 2 tells you something about the specific location of the urgent pointer, but most clients only care about 0 vs 'something nonzero' - the return value of wc_match, where -1 indicates a syntax error in the wildcard. - the return values from SSH-1 RSA-key loading functions, which use -1 for 'wrong passphrase' and 0 for all other failures (so any caller which already knows it's not loading an _encrypted private_ key can treat them as boolean) - term->esc_query, and the 'query' parameter in toggle_mode in terminal.c, which _usually_ hold 0 for ESC[123h or 1 for ESC[?123h, but can also hold -1 for some other intervening character that we don't support. In a few places there's an integer that I haven't turned into a bool even though it really _can_ only take values 0 or 1 (and, as above, tried to make the call sites consistent in not calling those values true and false), on the grounds that I thought it would make it more confusing to imply that the 0 value was in some sense 'negative' or bad and the 1 positive or good: - the return value of plug_accepting uses the POSIXish convention of 0=success and nonzero=error; I think if I made it bool then I'd also want to reverse its sense, and that's a job for a separate piece of work. - the 'screen' parameter to lineptr() in terminal.c, where 0 and 1 represent the default and alternate screens. There's no obvious reason why one of those should be considered 'true' or 'positive' or 'success' - they're just indices - so I've left it as int. ssh_scp_recv had particularly confusing semantics for its previous int return value: its call sites used '<= 0' to check for error, but it never actually returned a negative number, just 0 or 1. Now the function and its call sites agree that it's a bool. In a couple of places I've renamed variables called 'ret', because I don't like that name any more - it's unclear whether it means the return value (in preparation) for the _containing_ function or the return value received from a subroutine call, and occasionally I've accidentally used the same variable for both and introduced a bug. So where one of those got in my way, I've renamed it to 'toret' or 'retd' (the latter short for 'returned') in line with my usual modern practice, but I haven't done a thorough job of finding all of them. Finally, one amusing side effect of doing this is that I've had to separate quite a few chained assignments. It used to be perfectly fine to write 'a = b = c = TRUE' when a,b,c were int and TRUE was just a the 'true' defined by stdbool.h, that idiom provokes a warning from gcc: 'suggest parentheses around assignment used as truth value'!

All connections should now be rigorous about propagating end-of-file (or end-of-data-stream, or socket shutdown, or whatever) independently in both directions, except in frontends with no mechanism for sending explicit EOF (e.g. interactive terminal windows) or backends which are basically always used for interactive sessions so it's unlikely that an application would be depending on independent EOF (telnet, rlogin). EOF should now never accidentally be sent while there's still buffered data to go out before it.

New abstraction 'Seat', to pass to backends. This is a new vtable-based abstraction which is passed to a backend in place of Frontend, and it implements only the subset of the Frontend functions needed by a backend. (Many other Frontend functions still exist, notably the wide range of things called by terminal.c providing platform-independent operations on the GUI terminal window.) The purpose of making it a vtable is that this opens up the possibility of creating a backend as an internal implementation detail of some other activity, by providing just that one backend with a custom Seat that implements the methods differently. For example, this refactoring should make it feasible to directly implement an SSH proxy type, aka the 'jump host' feature supported by OpenSSH, aka 'open a secondary SSH session in MAINCHAN_DIRECT_TCP mode, and then expose the main channel of that as the Socket for the primary connection'. (Which of course you can already do by spawning 'plink -nc' as a separate proxy process, but this would permit it in the _same_ process without anything getting confused.) I've centralised a full set of stub methods in misc.c for the new abstraction, which allows me to get rid of several annoying stubs in the previous code. Also, while I'm here, I've moved a lot of duplicated modalfatalbox() type functions from application main program files into wincons.c / uxcons.c, which I think saves duplication overall. (A minor visible effect is that the prefixes on those console-based fatal error messages will now be more consistent between applications.)

Also, control character filtering can be tailored to be appropriate for individual front-ends; so far I don't promise anything other than not having made it any worse. I've tried to test this fairly exhaustively (although Mac stuff is untested, as usual). It all seems to basically work, but I bet there are new bugs. (One I know about is that you can no longer make the PuTTY window go away with a ^D at the password prompt; this should be fixed.)

Seat method to set the current trust status. In terminal-based GUI applications, this is passed through to term_set_trust_status, to toggle whether lines are prefixed with the new trust sigil. In console applications, the function returns false, indicating to the backend that it should employ some other technique for spoofing protection.

Add a new seat method to return the cursor position. The motivation is for the SUPDUP protocol. The server may send a signal for the terminal to reset any input buffers. After this, the server will not know the state of the terminal, so it is required to send its cursor position back.

Flip direction of window pos/size queries. Similarly to other recent changes, the frontend now proactively keeps Terminal up to date with the current position and size of the terminal window, so that escape-sequence queries can be answered immediately from the Terminal's own internal data structures without needing a call back to the frontend. Mostly this has let me remove explicit window-system API calls that retrieve the window position and size, in favour of having the front ends listen for WM_MOVE / WM_SIZE / ConfigureNotify events and track the position and size that way. One exception is that the window pixel size is still requested by Seat via a callback, to put in the wire-encoded termios settings. That won't be happening very much, so I'm leaving it this way round for the moment.
