absent, and also (I think) all the frontend request functions (such
as request_resize) take a context pointer, so that multiple windows
can be handled sensibly. I wouldn't swear to this, but I _think_
that only leaves the Unicode stuff as the last stubborn holdout.

lpage_send out into the line discipline, making them _clients_ of
the Unicode layer rather than part of it. This means they can access
ldisc->term, which in turn means I've been able to remove the
temporary global variable `term'. We're slowly getting there.
[originally from svn r2143]
As a result I've now been able to turn the global variables `back'
and `backhandle' into module-level statics in the individual front
ends. Now _that's_ progress!
[originally from svn r2142]
now compiles and runs again after the major destabilisation.
Unfortunately it wasn't feasible to actually encapsulate all of the
pty backend's data, since the utmp helper and the need to fork and
drop privileges before doing anything else at all rather confuses
matters. So the data handle passed around to the pty backend is a
null pointer, and the pty backend is just as global-ridden as it
always has been. Shame, but such is life.
[originally from svn r2128]
each backend now stores all its internal variables in a big struct,
and each backend function gets a pointer to this struct passed to
it. This still isn't the end of the work - lots of subsidiary things
still use globals, notably all the cipher and compressor modules and
the X11 forwarding authentication stuff. But ssh.c itself has now
been transformed, and that was the really painful bit, so from here
on it all ought to be a sequence of much smaller and simpler pieces
of work.
[originally from svn r2127]
- use smalloc/sfree, not malloc/free
- include <ctype.h>
- include <string.h> (although this doesn't shut the compiler up about
non-ANSI stricmp/strnicmp)
[originally from svn r2121]
only on clean exit, which is a departure from most xterm-alikes but
Ian reckons people will love me for it. If this turns out to be
wrong, we can always change the default for Unix.
[originally from svn r2120]
terminal.c was apparently relying on implicit initialisation to
zero, and also I've removed the backends' dependency on terminal.h
by having terminal sizes explicitly passed in to back->size().
[originally from svn r2117]
all the global and function-static variables out of terminal.c into
a dynamically allocated data structure. Note that this does not yet
confer the ability to run more than one of them in the same process,
because other things (the line discipline, the back end) are still
global, and also in particular the address of the dynamically
allocated terminal-data structure is held in a global variable
`term'. But what I've got here represents a reasonable stopping
point at which to check things in. In _theory_ this should all still
work happily, on both Unix and Windows. In practice, who knows?
[originally from svn r2115]
of the alternate-screen and save-cursor control sequences, with
subtly different semantics and entertaining interactions with the
usual ones. No thanks to xterm for doing so in the first place :-(
This checkin should sort it all out.
[originally from svn r2112]
it's automatically deactivated by any keypress, so that command-line
beeps from (e.g.) filename completion don't suddenly stop occurring,
but it still provides a rapid response to an accidental spewing of a
binary to your terminal.
[originally from svn r2107]
the latest release. This is so that .tar.gz snapshots for the Unix
port can be versioned as `0.53-20021016' or similar, meaning that
(e.g.) Debian version numbering can be monotonic between releases
and snapshots.
[originally from svn r2083]
set[ug]id. All privs-requiring pty operations are done at the very
start of the run, then privs are dropped before initialising GTK.
Utmp is handled by forking a still-privileged subprocess at this
point, and later asking it (through a pipe) to stamp utmp. The
subprocess cleans up utmp on exit, which has the additional
advantage that if the main pterm process suffers some sort of
unexpected termination (up to and including SIGKILL) the subprocess
can still mop up utmp.
