the bottom of the list like the special-purpose oddity it is).

privileges just before dying of a fatal signal. I'm not sure what I
intended it for in the first place; it certainly isn't doing its job
properly (no setgid), it's causing compiler warnings due to not
checking the setuid return code, and we can't think of any useful
purpose for it.

and returns its error message as a string, instead of actually
printing it on standard error and exiting. Now we can preserve the
previous error behaviour when we get a nonexistent font name at
startup time, but no longer rudely terminate in mid-session if the
user configures a bogus font name in Change Settings.

OS doesn't automatically assume it.
(It would seem faintly weird to me - surely opening the master end of
a given pty is a fairly good indication that you're _not_ a process
running inside it which wants to have it available as /dev/tty! But
you never know...)

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.

Well, at least across all command-line tools on both Windows and Unix,
and the GTK apps on Unix too. The Windows GUI apps fundamentally can't
write to standard output and it doesn't seem sensible to use message
boxes for these purposes :-)

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.

Unconditionally override the configured terminal size with the one

Default Settings had a terminal size set, Plink used this and thus
caused the server to use the wrong size.

won't helpfully optimise the call away if you do it just before
freeing something or letting it go out of scope. Use this for
(hopefully) every memset whose job is to destroy sensitive data that
might otherwise be left lying around in the process's memory.

and the argument list contains only one string, try again by passing
that single string to "$SHELL -c" to be parsed as a shell command.
This matches xterm's behaviour (as of xterm 261, at least), and means
in practice that users can do _either_ of 'pterm -e some command' and
'pterm -e "some command"'.
(A quick survey suggests that the majority of X terminal programs agree
with pterm's old behaviour of only supporting '-e some command',
except that gnome-terminal only supports the other behaviour and xterm
supports both. With that disagreement, I think supporting both is
probably the sensible thing.)

piece of keyboard handling: if Num Lock is on, numeric keypad keys are
eaten by the IM, so we must avoid passing them to the IM in the first
place if we're in any non-default numeric keypad mode (application or
Nethack).
This is a grubby way to do it, but the more obvious approach of just
moving the Nethack and app-keypad if statements up to above the IM
call doesn't work because those statements depend on the generic
Alt-prefix handling that happens just _below_ the IM call. So instead
I just repeat the list of keystrokes and modes in an if statement
conditionalising the IM call.

I've got this right so that it doesn't break any previous deliberate
keyboard-handling behaviour that's now _after_ the 'if (filter
keypress) return' statement.

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.

logevent(), which temporarily turn off the raw mode we've put stderr
into, so that they don't get called if the log_eventlog() call between
them is not _actually_ going to write to stderr.
Fixes a bug in which, if you define a Unix PuTTY saved session which
uses 'plink -nc' as a local proxy command and then run PuTTY
backgrounded from the shell with that session loaded, the subprocess
Plink would get SIGTTOU when it tried to muck about with stderr and
the whole thing would grind to a halt. I'm prepared to consider that
acceptable if Plink _really_ wants to write on standard error, but if
it doesn't, it should just carry on working in the background!

duplicate the strings they pass to gtk_entry_set_text. I was already
doing that in dlg_editbox_set, but forgot to add the same code when I
revamped FontSpec and Filename to contain dynamically allocated
strings (r9314 and r9316 respectively). This fixes a bug where, on
some versions of GTK (but apparently not up-to-date versions), loading
a saved session causes gibberish to appear in file-selector edit boxes
accompanied by a valgrind error.

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.

because (a) under that circumstance we won't be writing to utmp
anyway, and (b) if we aren't setuid, then we won't have created the
pty at the point we fork, so even if our subprocess _could_ have
written to utmp it wouldn't have done it right!
Spotted by valgrind (triggering on the access beyond the end of the
ttyname string in setup_utmp, clueing me in to it having been empty).

by introducing a wrapper around an individual unifont which falls back
to Pango (which already has built-in fallback) in the case where the
selected font doesn't support the glyph in question.

disturbance at the call sites.

font operations are now done directly using Xlib calls, and the only
interaction with GDK within the x11font mechanism is to get the X ids
for drawables, GCs and the X display itself.
This should remove an obstacle to porting to GTK3, and also makes the
XFontStruct for loaded fonts more readily available, which I hope will
come in handy for another plan I have in mind.

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).

from the older ones, test in decreasing order of preference and stop

of the variables set by the successful test for v1.

/dev/tty. That way, redirection of Plink's standard input will play
nicely with SSH sessions that need interactive login.

course. But we had no choice, due to the extra output part way through
keyboard-interactive.)

I think I have to consider this to be a separate but related change to
