received our communication once it had forgotten about the channel.

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!

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.
The wrapper itself is a (vestigial) subclass of unifont, to minimise
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.

makefile) as a side effect of running mkfiles.pl.
The automake docs observe that the BUILT_SOURCES list is only
automatically built by plain 'make' or 'make all' or a couple of other
targets, so the sequence './configure && make plink' from a freshly
unpacked tar file would previously fail for lack of empty.h.
If empty.h had important _content_ that needed to be built at compile
time, of course, I wouldn't be able to fix it like this; but since the
only important thing is the timestamp, I can just make sure it already
exists at the time of first build.

from forwarding data sources which will be good enough to last until
we close the socket, in the form of the override_throttle() functions.
So this finishes up the work in r9283, by manufacturing outgoing EOF
in response to incoming CLOSE on all channel types.

incoming CHANNEL_CLOSE, if it's the main session channel. The idea is
that invocations such as 'plink -T hostname sh' (running a shell
without a remote pty) can be exited by typing 'exit' to the remote
shell, without plink blocking forever waiting for outgoing EOF.
I think it would be better to do the same for all other channel types
too, but that would need an extra API call which I haven't
implemented yet.
[originally from svn r9283]
backend should unilaterally assume outgoing EOF when it sees incoming
EOF, if and only if the main session channel is talking to a pty.
(Because ptys don't have a strong concept of EOF in the first place,
that seems like a sensible place to draw the line.) This fixes a bug
introduced by today's revamp in which if you used Unix Plink to run a
console session it would hang after you hit ^D - because the server
had sent EOF, but it was waiting for a client-side EOF too.

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).

of preference so that the later ones overwrite the configured stuff
from the older ones, test in decreasing order of preference and stop
as soon as one is successful. Fixes a problem in which
autoconfiguration on a system containing only GTK 1 would go wrong
because the _failed_ test for GTK 2 would overwrite some but not all
of the variables set by the successful test for v1.

runs configure at the top level rather than the unix subdirectory. I'm
getting into the idea of even doing it that way myself, because then I
can do VPATH builds from the same source tree elsewhere.
(Autoconf seems to be fine with doing multiple VPATH builds from the
same source tree in different build directories, but gets upset if you
try to do a VPATH build when you've done a normal build in the real
configure directory. So this way I do what autoconf sees as _only_
VPATH builds.)

0.60-like and 0.61-like clients.

/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

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

port existed, and referred to the ability to configure the permissions

nonstandard port number when loading a saved session.
Occurs because those tools include be_none.c which defines no entries
in backends[] at all, as a result of which settings.c doesn't
recognise the word 'ssh' in the saved session's protocol field and
instead sets the protocol to something idiotic - which _then_ means
that when pscp.c forces the protocol to PROT_SSH, it also resets the
port number as it would when overriding a saved session specifying a
protocol other than SSH.
The immediate solution is to define a new be_ssh.c citing only
ssh_backend, and include that in the SSH-only tools. However, I wonder
if a better approach (perhaps when I redesign session loading and
saving) would be not to be so clever, and just have all the tools
contain a complete list of known protocol names for purposes of
understanding what's in the saved session data, and complain if you
try to use one they don't know how to actually speak.

'mkfiles.pl -u', it will do its normal processing, then run mkauto.sh
to regenerate configure and Makefile.in, then run configure in the
Unix subdirectory to regenerate unix/Makefile. So it's a handy
one-stop shop for going all the way from a modified Recipe to the
end-product Unix makefile, if you're adding source files during
development.

unchanged so that you end up doing a VPATH build in the top-level

--without-gtk as a means of manually overriding the makefile into one
building the command-line tools only (as it would if GTK were not
found at all at configure time).
[originally from svn r9240]
mkfiles.pl no longer generates a Makefile.in, but instead generates a
Makefile.am on which mkauto.sh runs automake. This means that the
autoconfigured makefile now does build-time dependency tracking (a
standard feature of automake-generated makefiles), and is generally
more like what Unix people will expect.
Some of the old-style make command-line settings (VER=-DRELEASE=foo,
XFLAGS=-DDEBUG) will still work; the COMPAT settings are better done
by autoconfiguration, and my habitual 'XFLAGS="-g -O0"' for an easily
debuggable build will actually not work any more because CFLAGS is
specified _after_ XFLAGS, so I should instead write 'make CFLAGS=-O0'
(-g is the default in automake, removed at 'make install' time).
The new makefile will automatically degrade into one that builds the
command-line tools only, in the case where GTK could not be found. In
principle, therefore, it should be an adequate replacement for _both_
the static Unix makefiles, Makefile.gtk and Makefile.ux. I haven't
actually retired those in this commit, but I'm pretty tempted.
