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.

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.

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.

Visual Studio's debugger complained about it just now. CloseHandle()

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.

No very good reason, but I've occasionally wanted to frob it to see if it
makes any difference to problems I'm having, and it was easy.
Tested that it does actually cause keepalives on Windows (with tcpdump);
should also work on Unix. Not implemented on Mac (does nothing), but then
neither is TCP_NODELAY.
Quite a big checkin, much of which is adding `keepalive' alongside `nodelay'
in network function calls.

brings up the context menu (and you can then paste by selecting
`Paste'). Should be more friendly to Windows-oriented users as
opposed to expatriate X users; also has the effect of making it more
difficult to paste into PuTTY by a single misplaced mouse click,
which has been a common theme of complaint recently.
For the moment, `Compromise' (the X-like behaviour with the right
and middle buttons reversed so that two-button users still get the
two most important functions) is still the default. I'm uncertain
that it might not be better to make the new option the default,
though, since the compromise option is optimal for _nobody_.

should allow us to use WS2-specific functionality to find out the

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.

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.

particular, the config box uses it in place of the word `PuTTY',
which means mid-session reconfig in pterm will look less strange
once I implement it. Also, while I'm at it, I've personalised all
the dialog boxes and menu items and suchlike so that PuTTYtel
actually claims to be PuTTYtel rather than PuTTY.

`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

provide at least a stub form of update_specials_menu().

being able to be a PuTTY as well as a pterm. In the process I've
also moved icky things like actually reading from the pty fd and
printing the `terminated on signal' messages into pty.c where they
obviously should have been in the first place. Also there's been one
interesting repercussion in the terminal code: terminal.c's
from_backend now calls term_out() directly rather than expecting the
front end to call it afterwards. This has had the entertaining side
effect of fixing a Windows-specific bug whereby activity in a port
forwarding through a PuTTY with a blinking cursor caused the cursor
to blink to ON (!!!!). So, a surprisingly far-reaching checkin as it
turns out...

malloc functions, which automatically cast to the same type they're
allocating the size of. Should prevent any future errors involving
mallocing the size of the wrong structure type, and will also make
life easier if we ever need to turn the PuTTY core code from real C
into C++-friendly C. I haven't touched the Mac frontend in this
checkin because I couldn't compile or test it.

opaque to all platform-independent modules and only handled within
per-platform code. `Filename' is there because the Mac has a magic
way to store filenames (though currently this checkin doesn't
support it!); `FontSpec' is there so that all the auxiliary stuff
such as font height and charset and so on which is needed under
Windows but not Unix can be kept where it belongs, and so that I can
have a hope in hell of dealing with a font chooser in the forthcoming
cross-platform config box code, and best of all it gets the horrid
font height wart out of settings.c and into the Windows code where
it should be.
The Mac part of this checkin is a bunch of random guesses which will
probably not quite compile, but which look roughly right to me.
Sorry if I screwed it up, Ben :-)

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.

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.

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.
