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.
[originally from svn r2613]
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.

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.

Windows. One day I want to replace all these fixed-size buffers with

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().
[originally from svn r2242]
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.

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

into the Config structure, though they won't stay there forever
since they will need to be moved out into platform-dependent config.

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...

beginning of a Unix port. It's nowhere near done, and currently it
won't even compile on Unix. But this represents the start of the
process of separating out platform-specific code, and also contains
the mkfiles.pl changes required to support a Unix makefile and a
non-flat source tree.

Bump username storage from 32 to 100 chars. Also replaced a couple of magic

(well, not Pageant or PuTTYgen). This should mean we get to
standardise almost all options across almost all tools. Also one
major change: `-load' is now the preferred option for loading a
saved session in PuTTY proper. `@session' still works but is
deprecated.

CONNECT, but contains an extensible framework to allow other

of scp.c, psftp.c and plink.c into it. Additionally, add `batch
mode', in which all the interactive prompts (bad host key, log file
exists, insecure cipher, password prompt) are disabled and safe
responses are assumed. (The idea being that if you run PSCP, for
example, in a cron job then you'd probably rather it failed and
exited instead of leaving the cron job wedged while it waits for
user input that will never arrive.)

^M instead of the Telnet New Line code. Unix-type telnetds don't

NL; and now someone has found one that can't deal with Telnet NL and
prefers ^M. Sigh.

sick of recompiling to enable packet dumps. SSH packet dumping is
now provided as a logging option, and dumps to putty.log like all
the other logging options. While I'm at it I cleaned up the format
so that packet types are translated into strings for easy browsing.
POSSIBLE SIDE EFFECT: in the course of this work I had to re-enable
the SSH1 packet length checks which it turns out hadn't actually
been active for some time, so it's possible things might break as a
result. If need be I can always disable those checks for the 0.52
release and think about it more carefully later.

and ESC[19;X;Yt (report size of _screen_ in _characters_, which it
isn't even obvious how to do when you've got a variable font size).

wraparound, not referencing vbell_timeout if in_vbell==FALSE, that

anyway.

multi-monitor aware and make the scrollbar separately configurable
in and out of full-screen mode. Also (not Wez's patch, this bit) fix
the case where the user reconfigures _while_ the window is
full-screen, and disables full-screening. (In this case the window
should return gracefully to normal, rather than losing all its title
bars and getting confused.)

term_out() can in turn call ldisc_send() which calls back to
from_backend() when local echo is enabled. This was giving rise to
crazy re-entrancy stuff and stack overflows. Instead from_backend()
deposits its data in a bufchain which term_out() empties the next
time it's called.

sanely on US keyboards - but it's no worse than it was in 0.51.
After 0.52 maybe I should fix it properly.

fiddle with the widths of characters in DBCS screen fonts, and (the
big one) one to enable a mode in which resizing the window locks the
terminal size and lets the font change, instead of vice versa. That

soon as it completed a successful recursive copy in both directions.
Also, one known bug: you can't specify a remote wildcard, because by
the nature of SFTP we'll need to implement the wildcard engine on
the client side. I do intend to do this (and use the same wildcard
engine in PSFTP as well) but I haven't got round to it yet.

Return -> Telnet End Of Line is _always_ enabled irrespective of the

introduce another layer of abstraction in SSH2 ciphers, such that a
single `logical cipher' (as desired by a user) can equate to more
than one `physical cipher'. This is because AES comes in several key
lengths (PuTTY will pick the highest supported by the remote end)
and several different SSH2-protocol-level names (aes*-cbc,
rijndael*-cbc, and an unofficial one rijndael-cbc@lysator.liu.se).

multiple switchable line disciplines, we now have a single unified

options.

advantages:
- protocol modules can call sk_write() without having to worry
about writes blocking, because blocking writes are handled in the
abstraction layer and retried later.
- `Lost connection while sending' is a thing of the past.
- <winsock.h> is no longer needed in most modules, because
"putty.h" doesn't have to declare `SOCKET' variables any more,
only the abstracted `Socket' type.
- select()-equivalent between multiple sockets will now be handled
sensibly, which opens the way for things like SSH port
forwarding.
[originally from svn r744]
- Robert de Bath's Compose key is now off by default and configurable on

use when they have data from the network. Replaces the utterly daft
inbuf / inbuf_head / term_out() interface, which only made sense
when feeding to terminal.c. (terminal.c now implements
from_backend() as a small function that gateways to the old
interface.)
As a side effect, from_backend() also has an `is_stderr' parameter,
so scp can once again separate the server's pronouncements on stderr
from the actual protocol progress on stdout.

- Try to deal with the problems where incoming data gets dropped
after decoding but before display.
- Scrollback behaviour has changed: instead of keying it off
`scroll' versus `delete top line', things now go into the
scrollback from _either_ of those but only if the primary screen
is selected. Should fix problems with `less' and talkers.
