65f9735b95 Stop calling gdk_input_add() with a zero flags word. If we don't
want to know about any input events on a socket, it's simpler not to
call gdk_input_add() on it at all.

I hesitate to say `fixes', but ... this change _causes to go away_
the weird problem I had with blank host key dialogs. I have no
understanding of the chain of cause and effect between gdk_input_add
with zero flags and missing redraw events, but it seems like a
change I should make anyway, so I'm going to do so and hope the
problem doesn't come back :-/

174bb7f1fd Fold up the `SSH' branch of the treeview by default; it's getting
quite big and tends to hide the existence of the `Serial' config
panel.

This is implemented by folding up every branch of depth 2 or more,
which with any luck might turn out to be general enough to carry
over unchanged if other branches start expanding. Then again, we may
have to fiddle with it again when that time comes; who knows?

32b25c13da Remove the loops that close all open fds before running a
subprocess. They were intended to make sure the child process didn't
inherit anything embarrassing or inconvenient from us, such as the
master end of its own pty, but now we instead do this by making sure
to set all our own fds to not-FD_CLOEXEC on creation. This should
fix Debian bug #357520.

(This doesn't seem to work _quite_ right in uxproxy.c's invocation
of a local proxy command: both ends of a GTK internal pipe end up in
the child process's fd space. This appears to be another GTK 1 bug,
inasmuch as it goes away when I build with Colin's preliminary GTK 2
patch; for the moment I think leaving that pipe lying around is
probably less harmful than hampering the proxy process's ability to
use extra fds by prior arrangement with PuTTY's parent process.)

4fa9564c90 Fix `puttygen-unix-perms': f_open(), PuTTY's wrapper on fopen, now
takes a third argument which is TRUE if the file is being opened for
writing and wants to be created in such a way that it's readable
only to the owner. This is used when saving private keys.

While I'm here, I also use this option when writing session logs, on
the general principle that they probably contain _something_
sensitive.

The new argument is only supported on Unix, for the moment. (I think
writing owner-accessible-only files is the default on Windows.)

fd6d9bd677 I've just discovered that using the saved sessions menu from Unix
PuTTY causes the child process to inherit a lot of socket fds from
its parent, which is a pain if one of them then ends up holding open
a listening socket which the parent was using for port forwarding
after the parent itself is dead.

Therefore, this checkin sprinkles FD_CLOEXEC throughout the Unix
platform directory wherever there looks like being a long-lived fd.

16510bf3b9 Support for an alternative mechanism for displaying wide characters
under X: instead of having two separate fixed-width fonts one of
which is twice the width of the other, you can instead have a single
font in which some characters are twice as wide as others.

This is implemented very simply: if you specify a wide font, it will
be used for wide characters, and if you don't then the normal font
will be used for wide characters (so they'd better _be_ wide in that
font, or there'll be trouble).

I got this idea from Jed, whose latest version supports UTF-8 and
requires a font of this type. If there are going to be X fonts like
that kicking around, there will doubtless be people who want to use
them.

631b494807 New command-line option in Plink (and PuTTY, though it's less useful
there): `plink host -nc host2:port' causes the SSH connection's main
channel to be replaced with a direct-tcpip connection to the
specified destination. This feature is mainly designed for use as a
local proxy: setting your local proxy command to `plink %proxyhost
-nc %host:%port' lets you tunnel SSH over SSH with a minimum of
fuss. Works on all platforms.

8c26b44ce6 Serial back end for Unix. Due to hardware limitations (no Linux box
I own has both an X display and a working serial port) I have been
unable to give this the full testing it deserves; I've managed to
demonstrate the basic functionality of Unix Plink talking to a
serial port, but I haven't been able to test the GTK front end. I
have no reason to think it will fail, but I'll be more comfortable
once somebody has actually tested it.

34f747421d Support for Windows PuTTY connecting straight to a local serial port
in place of making a network connection. This has involved a couple
of minor infrastructure changes:
 - New dlg_label_change() function in the dialog.h interface, which
   alters the label on a control. Only used, at present, to switch
   the Host Name and Port boxes into Serial Line and Speed, which
   means that any platform not implementing serial connections (i.e.
   currently all but Windows) does not need to actually do anything
   in this function. Yet.
 - New small piece of infrastructure: cfg_launchable() determines
   whether a Config structure describes a session ready to be
   launched. This was previously determined by seeing if it had a
   non-empty host name, but it has to check the serial line as well
   so there's a centralised function for it. I haven't gone through
   all front ends and arranged for this function to be used
   everywhere it needs to be; so far I've only checked Windows.
 - Similarly, cfg_dest() returns the destination of a connection
   (host name or serial line) in a text format suitable for putting
   into messages such as `Unable to connect to %s'.

c353c3cc97 The `socket' function in the backends is only ever checked to see if
it's NULL. Since we already have one back end (uxpty) which doesn't
in fact talk to a network socket, and may well have more soon, I'm
replacing this TCP/IP-centric function with a nice neutral
`connected' function returning a boolean. Nothing else about its
semantics has currently changed.

92e75acbb5 Shifts left and right by 32 were tripping a gcc warning (fatal with
-Werror, of course) about shifting by more than the range of a data
type. They only appeared in `if' statements testing sizeof(off_t),
but gcc warns even when the code is unreachable. I've removed the
conditional code (the general case should still work even on 32-bit
machines), and hacked each shift by 32 into a pair of shifts by 16.

Note that the gcc warning is not just a helpful indication that you
may be using the wrong data type; it's actually pointing out ANSI-
undefined behaviour in shifting a signed integer beyond the size of
its type.

Shift-hjklyubn for batch movement in NetHack, because they have

more useful. Unfortunately, PuTTY's NetHack keypad mode doesn't
support Ctrl-moves. Therefore, it does now :-)

8719f92c14 Revamp SSH authentication code so that user interaction is more
abstracted out; replace loops structured around a single interaction
per loop with less tortuous code (fixes: `ki-multiprompt-crash',
`ssh1-bad-passphrase-crash'; makes `ssh2-password-expiry' and
`proxy-password-prompt' easier).

The new interaction abstraction has a lot of fields that are unused in
the current code (things like window captions); this is groundwork for
`gui-auth'. However, ssh.c still writes directly to stderr; that may
want to be fixed.

In the GUI apps, user interaction is moved to terminal.c. This should
make it easier to fix things like UTF-8 username entry, although I
haven't attempted to do so. 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.)

fb581ac625 First crack at `terminal-modes' in SSH. PuTTY now sends ERASE by default,
Unix Plink sends everything sensible it can find, and it's fully configurable
from the GUI.

I'm not entirely sure about the precise set of modes that Unix Plink should
look at; informed tweaks are welcome.

Also the Mac bits are guesses (but trivial).

52a17ab04a 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.)

d0beed9aba Render timing.c robust in the face of strangeness. The strangenesses
in question vary per OS: on Windows the problem is that WM_TIMER
sometimes goes off too early, so that GetTickCount() is right and
the callback time is wrong, whereas on Unix the problem is that my
GETTICKCOUNT implementation comes from the system clock which means
it can change suddenly and non-monotonically if the sysadmin is
messing about (meaning that the timing of callbacks from GTK or
select timeouts is _more_ likely to be right than GETTICKCOUNT).
This checkin provides band-aid workarounds for both problems, which
aren't pretty but ought to at least prevent catastrophic assertion
failure.

   a new "-pgpfp" command-line option. (Except Unix PuTTYgen, which takes
   "--pgpfp" just to be awkward.)

 * Move the key policy discussion from putty-website/keys.html to

   Also tweak the text somewhat and include the fingerprints of the
   Master Keys themselves.
   (I've merged the existing autogeneration scripts into a single new

   as the webmonster reviews the changes and plumbs in the new script;

f73fcb0424 Add asynchronous callback capability to the askappend() alert box.
This was harder than verify_ssh_host_key() and askalg() put
together, because:
 (a) askappend() can be called at any time, since it's a side effect
     of data-logging functions. Therefore there can be an unfinished
     askappend() alert at any time, and hence the OS X front end has
     to be prepared to _queue_ other alerts which occur during that
     time.
 (b) logging.c has to do something with data that comes in while
     it's waiting for an answer to askappend(). It buffers it until
     it knows what the user wants done with it. This involved
     something of a reorganisation of logging.c.

means `front end has set an asynchronous alert box in motion, please
wait to be called back with the result', and each one is passed a
callback function pointer and context for this purpose.

I have not yet done the same to askappend() yet, because it will
take a certain amount of reorganisation of logging.c.

f5442209d4 Encapsulated most of the pty backend's variables into a proper data
structure, in preparation for wanting more than one of them in a
single process. This can't be done cleanly, because the whole
business with pty_pre_init pre-allocating the pty rather assumes we
want a known number of the things before we drop privileges; so
there's a horrid hack to make pty_pre_init work on platforms that
have at most one pty instance per process, but at the same time
things ought to work sensibly with more than one per process _if_
pty_pre_init isn't required.

* On Unix, for PF_UNIX sockets, return a counter rather than a constant along

* On Unix, interpret AF_INET6 addresses like Xlib does, returning the

  otherwise.  The latter is silly, but if I'm going to do anything more sane

I have tested that this compiles on Visual C 7 (so the nightlies

don't have IPv6 set up myself I haven't actually tested that it

blink when the window doesn't have focus, we don't schedule blink
timers at that point either.

Infrastructure change: term->has_focus should now not be written
directly from outside terminal.c. Instead, use the function
term_set_focus, which will sort out the blink timers as well.

7ecf13564a 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).

739de21c6d console_get_line() returns failure iff console_batch_mode is set, whereas
before is would return success and the empty string. IMO this makes `-batch'
much more useful; before, utilities such as Plink in `-batch' mode would
attempt to plough on using empty strings for usernames, passwords, and so on.

17b0d8c58e Support the SSH-2 mechanism for sending signals to a running session. Neither
of the SSH servers I conveniently have access to (Debian stable OpenSSH --
3.4p1 -- and lshd) seem to take a blind bit of notice, but the channel
requests look fine to me in the packet log.

I've included all the signals explicitly defined by
draft-ietf-secsh-connect-19, but I've put the more obscure ones in a submenu
of the specials menu; there's therefore been some minor upheaval to support
such submenus.

1b3eb3e20d Markus Kuhn's UTF-8 page
http://www.cl.cam.ac.uk/~mgk25/unicode.html#activate
feels strongly that it should be easy to make _all_ your
applications work in UTF-8 mode, without having to remember a switch
for each one. Every application should simply note a UTF-8 locale
setting and switch into UTF-8 mode automatically.

Therefore, for the Unix port only, there's now a checkbox, enabled
by default, which causes the drop-down Translation box to be
overridden if the locale indicates UTF-8. Anyone who doesn't like
this, or doesn't like MGK, is welcome to turn it straight back off.

I'm not _completely_ convinced by MGK's argument myself; for
xterm/pterm to do _useful_ UTF-8 you also need to specify a decently
Unicode-capable font, and there's no way _that_ can be automagically
done on noticing a locale setting. But it's a de facto standard
(i.e. xterm does it :-) so I might as well at least be _able_ to
support it.

859d92a577 Moved the environment variables config block out of the Telnet panel
into the Connection panel, and implemented support for the SSH2
"env" request. (I haven't yet found a server which accepts this
request, so although I've visually checked the packet log and it
looks OK, I haven't yet been able to do a full end-to-end test.)
Also, the `pty' backend reads this data and does a series of
`putenv' commands before launching the shell or application.

This is mostly because in last week's UTF-8 faffings I got
thoroughly sick of typing `export LANG=en_GB.UTF-8' every time I
started a new testing pterm, and it suddenly occurred to me that
this would be precisely the sort of thing you'd want to have pterm
set up for you, particularly since you can configure it alongside
the translation settings and so you can ensure they match up
properly.

089775eb02 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.

709a94e5f2 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.

c2914f2191 Fix for `psftp-pscp-ignore-load': Default Settings is now loaded
before "-load" is processed so that it doesn't clobber it.

I've also changed the semantics of "-load" slightly for PSCP, PSFTP,
and Plink: if it's specified at all, it overrides (disables) the
implicit loading of session details based on a supplied hostname
elsewhere (on the grounds that the user is more likely to want the
"-load" session than the implicit session). (PuTTY itself doesn't do
implicit loading at all, so I haven't changed it.)

This means that all the PuTTY tools' behaviour is now consistent iff
"-load" is specified (otherwise, some tools have implicit-session, and
others don't).

However, I've not documented this behaviour, as there's a good chance
it will be swept away if and when we get round to sorting out how we
deal with settings from multiple sources. It's intended as a "do
something sensible" change.

92db92af5a Control of 'addr' is now handed over to {platform_,}new_connection() and
sk_new() on invocation; these functions become responsible for (eventually)
freeing it. The caller must not do anything with 'addr' after it's been passed
in. (Ick.)

Why:
A SOCKS5 crash appears to have been caused by overzealous freeing of
a SockAddr (ssh.c:1.257 [r2492]), which for proxied connections is
squirreled away long-term (and this can't easily be avoided).

It would have been nice to make a copy of the SockAddr, in case the caller has
a use for it, but one of the implementations (uxnet.c) hides a "struct
addrinfo" in there, and we have no defined way to duplicate those. (None of the
current callers _do_ have a further use for the SockAddr.)

As far as I can tell, everything _except_ proxying only needs addr for the
duration of the call, so sk_addr_free()s immediately. If I'm mistaken, it
should at least be easier to find the offending free()...

ef2ccb56cf Allow pterm to receive selections in compound text format. Doesn't
actually _understand_ compound text yet - anything with
non-ASCII-or-8859-1 characters will fail miserably - but it will at
least successfully receive plain text if the pasting application
doesn't see fit to give it out in any other format.

99bef3d3cf Debian bug #193013 points out that the (default-)one-pixel border is
not redrawn when the window background colour is reconfigured mid-
session. In addition, the Official Window Background is not reset,
meaning that opaque resizes etc will flicker in the old background
colour. This checkin should fix both.

80c3a23abc I think I've just fixed Debian bug #166396. The +ut option was
causing pty_utmp_helper_pipe to be closed, but its fd was kept
around even when stale, and closed again when the main child process
terminated - by which time the fd number had been reused for a
rather more vital fd, which GTK didn't appreciate having closed
under its feet. Hence, spin on POLLNVAL. Should now be sorted.

4b5ce3f46f pterm will now attempt to guess suitable names for any missing fonts
from the ones given; so it'll ask for a font twice as wide as your
base one if you don't specify a wide font, it'll ask for a bolded
version of your base font if you don't specify a bold font, and
similarly for a wide/bold font. Should solve Debian bug #187389; at
least it works for me.

9a242f06ba Fixes for Debian bug #192701 (64-bit gccs warn about casts between
ptrs and ints of different size and -Werror makes this serious).
The GTK bits are done by Colin's patch to use GINT_TO_POINTER
(thanks); the uxnet bits are done by cleaning up the rest of the
code. In particular, network.h now typedefs `OSSocket' to be a type
capable of holding whatever the OS's socket data type is that
underlies our socket abstraction. Individual platforms can make this
typedef themselves if they define OSSOCKET_DEFINED to prevent
network.h redoing it; so the Unix OSSocket is now int. Default is
still void *, so other platforms should be unaffected.

8460ecd27d Yesterday's proxy enhancements also slightly nadgered the config
box, in that it started to expand under the weight of proxy options.
Now fixed, by folding the SOCKS version selector into the general
proxy type selector so there's one single 5- or 6-way radio button
set split over two lines. settings.c has of course grown a backwards
compatibility wart to deal with legacy config data.

f6a208fbdd First half of `pageant-async' work. agent_query() is now passed a
callback function; it may return 0 to indicate that it doesn't have
an answer _yet_, in which case it will call the callback later on
when it does, or it may return 1 to indicate that it's got an answer
right now. The Windows agent_query() implementation is functionally
unchanged and still synchronous, but the Unix one is async (since
that one was really easy to do via uxsel). ssh.c copes cheerfully
with either return value, so other ports are at liberty to be sync
or async as they choose.

a font with X-encoded line drawing glyphs.)

gtk_window_set_title() overwrote both titles at once. Icon title is

whole icon/window title separation _anyway_ they default to being
separate.

ec3595f7d4 Removing items from a list box using gtk_container_remove is nasty,
because when the selected item is removed the selection moves on to
another item. Thus, calling dlg_listbox_clear causes repeated
selchanges in the list, which in turn cause repeated valchanges if
the list is attached to a combo box. This has been completely
scuppering the Translation panel.

At the moment, we have to assume that getaddrinfo() will only return AF_INET

later.  Fixing this is probably best done by redesigning the PuTTY network

d93f7113d1 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.

fe666b2432 While writing gtkdlg.c I learned how to specify a window's initial
position in GTK, so I can now implement the other half of -geometry
which I'd previously believed to be impossible in GTK. It's still
not perfect, because GTK apparently provides no way for us to get
hold of the X reparent event in order to support negative geometries
in a manner which takes account of the WM borders; but for positive
position it's at least an improvement on the previous version!
