areas of the code. Not all back-ends have been tested, but Telnet and SSH
behave reasonably.
Incidentally, almost all of this patch was written through Mac PuTTY,
admittedly over a Telnet connection.

link-module const variable `be_default_protocol' which suggests a sensible
default to the front end (which can ignore it). (DEFAULT_PORT is replaced by a
lookup in the backend[] table.)
Still not pretty, but it does mean that the recent fix for `ssh-default'
doesn't break PuTTYtel.

holdout static I hadn't noticed; unicode.c had one too; and a large
number of statics that were perfectly OK due to being constants have
been made `const', with assorted `const' repercussions all over the
place. I now declare `remove-statics' to be fixed.
[originally from svn r2594]
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.
[originally from svn r2592]
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.

and have a function to pass in a new one. (Well, actually several
back ends don't actually bother to do this because they need nothing
out of Config after the initial setup phase, but they could if they
wanted to.)
[originally from svn r2561]
and term_reconfig() now passes in a new structure which is copied
over the top. This means that the old and new structures can be
compared, and the _current_ as well as default states of auto wrap
mode, DEC origin mode, BCE, blinking text and character classes can
be conveniently reconfigured in mid-session without requiring a
terminal reset.

the remote IP/port data provided by the server for forwarded
connections. Disabled by default, since it's incompatible with SSH2,
probably incompatible with some X clients, and tickles a bug in
at least one version of OpenSSH.
[originally from svn r2554]
we're going to be a security program, we can at least make a token
effort to use the most secure local X auth available! And I'm still
half-tempted to see if I can support it for remote X servers too...
[originally from svn r2537]
Windows and Mac backends have acquired auth-finding functions which
do nothing; Unix backend has acquired one which actually works, so
Plink can now do X forwarding believably.
(This checkin stretches into some unlikely parts of the code because
there have been one or two knock-on effects involving `const'. Bah.)
[originally from svn r2536]
and pterm need at least one default setting to be _different_ (pterm
needs the default term type to be `xterm', while plink needs it to
be taken from $TERM). So here's a completely new alternative
mechanism for platform- and app-specific default settings. Ben will
probably want to check the integrity of the Mac port, since I've
fiddled with it without testing that it still compiles.
[originally from svn r2513]
right-hand half of a CJK wide character; correct handling of cut and
paste when CJK text wraps between lines _irrespective of the parity
of the starting column_; correct handling of wordness values
irrespective of which half of a CJK character the user
double-clicked on; correct handling when any terminal activity
overwrites only one half of a CJK wide character. I think we now
behave marginally better than xterm in this respect (it has a redraw
problem when you overwrite the RH half of a CJK char), so I'm happy.
Also redefined the internal UCSWIDE marker to something in the
surrogate range, while I'm here, so that U+303F is available for use
by actual users.
[originally from svn r2426]
know what that encoding actually is, we can do our best to support
additional charsets (VT100 linedrawing, SCO ACS, UTF-8 mode) using
the available characters; if we don't, we fall back to a mode where
we disable all Unicode cut-and-paste and assume any Unicode
character is undisplayable.

open an existing saved session. This has entailed adding an extra hook to
settings.c to allow for loading settings other than by name.

SockAddr, which just contains an unresolved hostname and is created
by a stub function in *net.c. It's an error to pass this to most of
the real-meat functions in *net.c; these fake addresses should have
been dealt with by the time they get down that far. proxy.c now
contains name_lookup(), a wrapper on sk_namelookup() which decides
whether or not to do real DNS, and the individual proxy
implementations each deal sensibly with being handed an unresolved
address and avoid ever passing one down to *net.c.

the benefit of X font names which are rather more verbose than
Windows. One day I want to replace all these fixed-size buffers with
sensible dynamically allocated stuff, but not today.

This introduces a new front-end function, do_scroll(), which is expected to
scroll a part of the physical display and cause repaint events for any
areas that couldn't be scrolled (e.g. because they were hidden).
scroll_display() is a wrapper around this which also updates disptext to
match.
Currently, scroll_display is only used in response to user scrollback requests
(via term_scroll()), but extending scroll() to use it as well should be
easy.
All of this is conditional on the front end's defining OPTIMISE_SCROLL, since
only the Mac front end currently implements do_scroll().

This doesn't include any mkfiles.pl glue, and is missing one or two other
fixes. The terminal emulator is kind of working, though, as, I believe, is
the store module. Everything else is yet to be done.
[originally from svn r2226]
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.
[originally from svn r2147]
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]
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]
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]
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.

login shell or not. Also moved these new pieces of configuration
into the Config structure, though they won't stay there forever
since they will need to be moved out into platform-dependent config.
[originally from svn r2060]
The current pty.c backend is temporarily a loopback device for
terminal emulator testing, the display handling is only just enough
to show that terminal.c is functioning, the keyboard handling is
laughable, and most features are absent. Next step: bring output and
input up to a plausibly working state, and put a real pty on the
back to create a vaguely usable prototype. Oh, and a scrollbar would
be nice too.
In _theory_ the Windows builds should still work fine after this...
