3e22c99c9a Fix another error-reporting bug, in which sk_newlistener would fail to
capture the error code if listen() returned an error, and instead pass
0 (saved from the previous successful bind) to winsock_error_string.

69113b16b1 Add a fallback case to winsock_error_string() which makes it call
FormatMessage to get the OS's text for any error not in our own
translation table. Should eliminate the frustrating 'unknown error'.

(I haven't chosen to use FormatMessage unconditionally, because it
comes out with enormous messages along the lines of "No connection
could be made because the target machine actively refused it" in place
of "Connection refused" and I'm Unixy enough to prefer the latter.
Also, on older Windowses, Winsock error codes are in a separate API
segment and don't work with FormatMessage anyway.)

251876b594 Windows's sk_address_is_local() was returning the wrong answers for
IPv6 addresses, because I'd mistakenly cast an ai_addr to the low-

58870f60e4 If you configure Unix PuTTY to use a proxy, tell it to even proxy
localhost connections, and also enable X forwarding in such a way that
it will attempt to connect to a Unix-domain X server socket, an
assertion will fail when proxy_for_destination() tries to call
sk_getaddr(). Fix by ensuring that Unix-domain sockets are _never_
proxied, since they fundamentally can't be.

d5836982e2 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.

aba05b7180 Patch from Robert de Bath to substantially simplify timing.c.
The previous platform-dependent ifdefs, switching between a system
which tried to cope with spurious callbacks (which I'd observed on
Windows) and one which tried to cope with system clock jumps (which
can happen on Unix, if you use gettimeofday) have been completely
removed, and replaced with a much simpler approach which just copes
with system clock jumps by triggering any timers immediately.

None of the resulting effects should be catastrophic (the worst thing
might be the waste of CPU in a spurious rekey, but as long as the
system clock isn't jumping around _all_ the time that's hardly
critical) and in any case the Unix port has had a long-standing oddity
involving occasional lockups if pterm or PuTTY runs for too long,
which hopefully this should replace with a much less bad failure mode.
And the code is much simpler, which is not to be sneezed at.

UTF-16 string for display. Meanwhile, accidental uses of wchar_t have

e350ca2b4e WM_SIZE/SIZE_MAXIMIZED can show up even during an interactive resize,
so we should ensure we treat it the same way as other WM_SIZEs that
show up during that time: set the width and height in conf, and set
the flag to have that width and height enacted on WM_EXITSIZEMOVE.

Fixes a bug in which dragging a PuTTY window directly from the Win7
snapped-to-half-screen position to the snapped-to-maximised state
would leave the terminal in the pre-snapped size.

9c75fe9a3f Change the semantics of 'FontSpec' so that it's a dynamically
allocated type.

The main reason for this is to stop it from taking up a fixed large
amount of space in every 'struct value' subunion in conf.c, although
that makes little difference so far because Filename is still doing
the same thing (and is therefore next on my list). However, the
removal of its arbitrary length limit is not to be sneezed at.

947962e0b9 Revamp of EOF handling in all network connections, pipes and other
data channels. Should comprehensively fix 'half-closed', in principle,
though it's a big and complicated change and so there's a good chance
I've made at least one mistake somewhere.

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. (May help fix 'portfwd-corrupt', and also I
noticed recently that the ssh main session channel can accidentally
have MSG_EOF sent before the output bufchain is clear, leading to
embarrassment when it subsequently does send the output).

a1f3b7a358 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.

af78191a9c Make Pageant use the same SID-selection logic as the Pageant client
code (as introduced in r9043), so that it uses the user SID rather
than the default SID.

This does change the access-control model, in that a Pageant running
with administrator privilege will now serve keys to an unprivileged
PuTTY running as the same user who started Pageant. Owen and I think
this isn't a problem (in particular, it will still not serve keys to a
_different_ user).

More importantly, making the Pageant client and server code work the
same way means that PuTTY and Pageant can still talk to each other
when UAC is turned off, which we've had several reports of r9043
having broken.

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

00b32eda3c 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 :-)

0adb957784 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.

1a03fa9292 Support for Windows 7 jump lists (right-click on a program's taskbar
icon, even if the program isn't running at the time, to be presented
with an application-defined collection of helpful links). The current
jump list is updated every time a saved session is loaded, and shows
the last few launchable saved sessions (i.e. not those like Default
Settings) that were loaded. Also, if Pageant or PuTTYgen or both is in
the same directory as the PuTTY binary, the jump list will present
links to launch those too.

Based on a patch sent last year by Daniel B. Roy, though it's barely
recognisable any more...

17f6ca0360 Pay attention to the width and height provided in WM_SIZE even when
restoring a maximised window.

Failure to do this was noticeable in the following scenario (again
using Aero UI enhancements):
 1. resize window using topmost resize handle, and move pointer to top
    of screen which 'maximises' the window vertically
 2. now maximise the window properly using the maximise button in top
    right
 3. now restore. Notepad restores to its position before step 1,
    because Aero remembers that position for the purpose, but PuTTY
    thinks it knows better. Only now it doesn't any more.

0b6407878a Reorganise handling of WM_SIZE to fix two generality problems.
Firstly, maximise and restore events were expected never to occur
during an interactive resize process (i.e. between WM_ENTERSIZEMOVE
and WM_EXITSIZEMOVE), but in fact Aero now allows this to happen if
you move the pointer to the top of the screen while dragging the
window.

Secondly, plain old WM_SIZE events were expected never to occur
_outside_ interactive resizes, but Aero permits that too (e.g.
Windows-left and Windows-right), and also third-party window
repositioning tools will send these.

406e62f77b Cleanups of the GSSAPI support. On Windows, standard GSS libraries
are now loaded from standard locations (system32 for SSPI, the
registry-stored MIT KfW install location for KfW) rather than using
the risky default DLL search path; I've therefore also added an
option to manually specify a GSS DLL we haven't heard of (which
should in principle Just Work provided it supports proper GSS-API as
specified in the RFC). The same option exists on Unix too, because
it seemed like too useful an idea to reserve to Windows. In
addition, GSSAPI is now documented, and also (unfortunately) its GUI
configuration has been moved out into a sub-subpanel on the grounds
that it was too big to fit in Auth.

SSPI. I don't know for sure whether further tweaking will be needed

d992932e1e Since r7266, it's been possible to get a hostname into Default Settings; but
plink did not cope gracefully with this -- it was not possible to override that
hostname on the command line (attempts at doing so would be treated as part of
the remote command).
Fix this by applying the principle of r7265: if the user didn't explicitly
specify that they wanted to launch the hostname in the default (for instance
with '-load "Default Settings"', we assume they don't want to, and such a
hostname doesn't count when deciding whether to treat a non-option argument as
hostname or command.

d699530e4c Since r8305, Unix PuTTY has always "upgraded" an X11 display like "localhost:0"
to a Unix-domain socket. This typically works fine when PuTTY is run on the
same machine as the X server, but it's broken multi-hop X forwarding through
OpenSSH; when OpenSSH creates a proxy X server "localhost:10", it only listens
on TCP, not on a Unix-domain socket.

Instead, when deciding on the details of the display, we actively probe to see
if there's a Unix-domain socket we can use instead, and only use it if it's
there, falling back to the specified IP "localhost" if not.

Independently, when looking for local auth details in Xauthority for a
"localhost" TCP display, we prefer a matching Unix-domain entry, but will fall
back to an IP "localhost" entry (which would be unusual, but we don't trust a
Windows X server not to do it) -- this is a generalisation of the special case
added in r2538 (but removed in r8305, as the automatic upgrade masked the need
for it).
(This is now done in platform-independent code, so a side-effect is that
get_hostname() is now part of the networking abstraction on all platforms.)

added that control to Connection/SSH/X11 when the parent panel
Connection/SSH didn't exist. Making the control conditional on the

but I now realise that the setting should never have been presented
in mid-session in any case.)

201c2c295b Patch from Gert-Jan Vons: create an event handle to go in the
OVERLAPPED structure in output threads, as we already do for input
threads. This apparently sorts out a hanging issue with serial ports
when trying to do simultaneous read and write, because (GJV says,
and it sounds plausible to me) in the absence of that event object
Windows signals the file handle itself to notify GetOverlappedResult
that it can return - and since the file handle might be being
signalled by a read operation instead, that leads to ambiguity.
Using an explicit event object in both directions means Windows
always knows which way the data is going.

Also a trivial fix in handle_output_new(), which was referencing the
wrong element of a union due to a copy and paste error. (Since the
result was address-taken and cast to void *, this wasn't a
functional error, but it was conceptually wrong.)

75913faf82 Weaken the assertion in general_textout(). It was failing in the
case of double-width text (ESC # 3, ESC # 4, ESC # 6), because the
string passed to it was not truncated to the same width as the
clipping rectangle. (In fact, it _can't_ reliably be, in the case
where the window width is odd.) So instead we just assert that we
managed to _at least_ fill the clipping rectangle, not that we
exactly filled it.

The problem is easily reproduced by sending ESC # 8 (fill the screen
with Es) followed by ESC # 3. It doesn't typically happen, though,
if you _manually_ fill the screen with Es, because in that case
PuTTY's terminal buffer ends up being filled with CSET_ACP | 'E' or
similar, which means that general_textout() never gets called
because one of the other branches of do_text_internal() does the
work instead. ESC # 8 will fill the terminal buffer with genuine
_Unicode_ 'E' characters, which exercises the failing code path.

81dafd906e Change how we handle the Ssh_gss_buf type. Previously, we defined it
ourselves, but on Unix then assumed it was compatible with the system's
gss_buffer_desc, which wasn't the case on LP64 systems.  Now, on Unix
we make Ssh_gss_buf into an alias for gss_buffer_desc, though we keep
something similar to the existing behaviour on Windows.  This requires
renaming a couple of the fields in Ssh_gss_buf, and hence fixing all
the references.

Tested on Linux (MIT Kerberos) and Solaris.  Compiled on NetBSD (Heimdal).
Not tested on Windows because neither mingw32 nor winegcc worked out of the
box for me.  I think the Windows changes are all syntactic, though, so
if this compiles it should work no worse than before.

that we can now support X authority lookups on Windows as well
provided the user points us at an appropriate X authority file in
the standard format. A new Windows-specific config option has been
added for this purpose.

6e2501be77 Move out of the SockAddr structure the mutable fields "ai" and
"curraddr", and turn "family" into a macro-derived property of the
other fields. The idea is that this renders SockAddrs immutable once
created, which should open up the possibility of duplicating and
reusing one without having to redo the actual DNS lookup.

I _hope_ I haven't broken anything. The new code architecture
contains several rather dubious-looking operations (namely the
arbitrary choice of the first returned address in functions like
sk_getaddr and sk_address_is_local - what if, for instance, a DNS
lookup returned a local and a non-local address?), but I think they
were functionally just as dubious beforehand and all this change has
done is to make them more obviously so to a reader.

4829802c43 Good grief. When I originally wrote the local proxy code two years
ago, I apparently caused all data received from local proxies to be
unconditionally tagged as TCP Urgent. Most network backends ignore
this, but it's critical to the Telnet backend, which will ignore all
Urgent-marked data in the assumption that there's a SYNCH on its way
that it should wait for. Nobody has noticed in two years, presumably
meaning that nobody has ever tried to do Telnet over a local proxy
in that time.

e81a8cf795 Been meaning to do this for years: introduce a configuration option
to manually tweak the host name and port number under which the SSH
host key is read and written.

I've put it in the cross-platform Connection panel. Partly under the
flimsy pretext that other backends _can_ use it if they so wish (and
in fact it overrides the host name for title-bar purposes in all
network backends, though it has no other effect in anything but
SSH); but mostly because the SSH panel was too full already :-)

represent a launchable session, unless the user can be construed to
have really meant it. This means:
 - starting up PuTTY when the Default Settings are launchable still
   brings up the config box, and you have to hit Open to actually
   launch that session
 - double-clicking on Default Settings from the config box will load
   them but not launch them.
On the other hand:
 - explicitly loading the Default Settings on the command line using
   `-load' _does_ still launch them.

ab795ba008 Version management updates for the new bob build script. There's now
a fourth class of PuTTY version tags in addition to release,
snapshot and unidentified: we now have `Custom build r1234',
indicating a build made from that SVN revision in a context other
than that of a dated snapshot. The build script generates these when
it doesn't know what else to do; `unidentified builds' will now only
occur when you run nmake from the command line.

Also, the build script now generates sensible version data in the
installer to match this. So I _think_ we should now be set to use
bob to generate installer builds of the nightly snapshots, although
of course I'll have to wait until tomorrow to test one.

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.

writing owner-accessible-only files is the default on Windows.)

dbbd6eb5ec Fix `win-randseed-location': use SHGetFolderPath() to find the
Application Data directory in preference to the old-fashioned
attempt to find the user's home directory, and use the _local-
machine_ Application Data directory in preference even to that.

SHGetFolderPath() is called via GetProcAddress, so this degrades
gracefully on old Windowses. (Tested myself on Win95.)

As part of this change, we now search for a location for the seed
file separately for reading and writing, so that installing the new
PuTTY should cause a seamless migration as the old seed file is read
from the old location and then a new one written to the new location.

`putty -cleanup' attempts to delete the seed file from _all_
affected locations.

Naturally, a user-specified seed file path in the Registry still
takes priority over all other means of finding the location.

6c3f4b3baa The remaining issue in `win-askappend-multi' appears to have been
caused by the MessageBox() internal message loop eating WinSock
FD_READ notifications, which then don't reappear afterwards because
you have to explicitly prod a socket in order to get a repeat
notification on it.

Hence, here's a piece of infrastructure which seems to sort it out:
a new winnet.c function called socket_reselect_all(), whose function
is to go through all currently active sockets and re-run
WSAAsyncSelect() on them, causing repeat notifications for anything
we might have missed. I call this after every call to MessageBox(),
and that seems to solve the problem.

(The problem was actually masked in very recent revisions, probably
by the reinstatement of pending_netevent in r7071. However, I don't
believe that was a complete fix. This should be.)

a8bdd536c8 Shiny new script which constructs the various icons for the PuTTY
suite. In a dramatic break with tradition, I'm actually checking in
the resulting icon files as well as the script that generates them,
because the script requires Python and ImageMagick and I don't think
it's reasonable to require that much extra infrastructure on
everyone checking out from Subversion.

The new icons should be _almost_ indistinguishable from the old
ones, at least at the 32x32 resolution. The immediately visible
change is that all the icons now come in 16x16, 32x32 and 48x48
formats, in both 16 colours and monochrome, instead of an ad-hoc
mixture of whichever ones I could be bothered to draw.

The same code can also be adapted to generate icons for the GTK port
(although icons for the running programs don't seem to be supported
by GTK 1 - another reason to upgrade to GTK 2!).

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.

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.)

a2338cb6f2 Fix breakage of `Restart Session' in r6802. When restarting the
session, we were clearing the new session_closed flag, but failing
to clear must_close_session; with that set, the session was being
opened but immediately re-closed.

33e827818a Add a mini-rant to the top comment explaining why threads are
required. (I just tried getting rid of them; it worked fine for
serial ports, but not for anything else. The Windows I/O API sucks.)

bb6482c35d Explicitly closing logctx on various kinds of error exit means that
the log file gets fclosed properly and the critical last few
messages might be recoverable from the log file more often...

f0a9c33f25 The Windows HANDLE type, despite being a `void *', does not actually
behave like a pointer. In particular, the right thing to set a
HANDLE to to indicate that it's invalid is INVALID_HANDLE_VALUE, not
NULL. Crack down on sloppy use of NULL HANDLEs across all Windows
code.

(There is one oddity, which is that {Create,Open}FileMapping are
documented to return a NULL HANDLE instead of INVALID_HANDLE_VALUE
on failure. Shrug. If MS want to be inconsistent, I suppose I have
to live with it.)

d38ea07616 Inhibit the Serial configuration panel in mid-session if the session
isn't a serial one. In particular, this causes pterm not to fail an
assertion if you select `Change Settings'. Ahem.

4c460326d9 Apparently MsgWaitForMultipleObjects doesn't always return the
values one might expect, which means that GetMessage() was
occasionally blocking the process. That appears to be the last of
the annoying data loss issues, so I think the Windows serial back
end actually looks vaguely reliable now. Phew.

32582f0fab Eep! Next bit flag after 1 and 2 is _4_, not 3. Perhaps it's time I

a485923ae4 Reading 4K at a time from a serial port turns out to be a bit
unfriendly in an interactive session, because at 19200 baud it takes
nearly two seconds to receive that much data, and as long as the
data is flowing continuously Windows waits until it has a full
buffer. So here's another annoying flag in the winhandl API, which
restricts reads to length 1 so that serial output shows up as it
appears.

(I tried this yesterday, but without the OVERLAPPED fix in r6826 it
behaved very erratically. It now seems solid.)

2aedc83f8d Apparently it helps for an OVERLAPPED structure to contain a valid
event handle. This seems to have fixed _some_, but not all, of the
curious data loss issues in the Windows serial backend.

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.

ae83801b28 Because not all OSes will support the same set of serial port
options, here's a slight change to the API of ser_setup_config_box()
to make it filter its parity and flow control options using
platform-supplied bit masks.
