Jacob Nevins [Sun, 15 Jun 2008 12:39:09 +0000 (12:39 +0000)]
Exorcise beeps from the Colours pane in Gtk.

The colour list box beeped at the user whenever it found that
something other than exactly one colour was selected. This seems to
happen implicitly in Gtk when the pane is changed. In Gtk1, this gave
you a beep whenever you left the Colours dialog after having selected
a colour from the list; in Gtk2, you additionally got a beep _every_
time you subsequently re-entered the Colours dialog (for reasons I
haven't investigated). Windows was unaffected.

Also, in Gtk (unlike Windows), it's possible for the user to go back
to the state where no items in the list box are selected at all.

For these reasons, stop beeping at the user, and instead blank the RGB
edit boxes as a hint that edits to them would be futile. (Really we
should be disabling them entirely, but the cross-platform edit
controls aren't up to that yet.)

In the new unified font handling, my strategy so far for combining
client- and server-side fonts into a single namespace was mainly to
hope there would naturally be no collisions, and to provide
disambiguating "client:" and "server:" prefixes for manual use in
emergencies.

Jacob points out, however, that his system not only has a namespace
clash but worse still the clash is at the name "fixed", which is our
default font! So, modify my namespace policy to use the
disambiguating prefixes everywhere by default, and use _unprefixed_
names only if the user types one in by hand.

In particular, I've changed the keys used to store font names in
Unix saved session files. Font names read from the new keys will be
passed straight to the new unifont framework; font names read from
the old keys will have "server:" prepended. So any existing
configuration file for GTK1 PuTTY should now work reliably in GTK2
PuTTY and select the same font, even if that font is one on which
your system (rather, your client+server combination) has a font
namespace clash.

Refactor the font handling code: I've moved all the code that
explicitly deals with GdkFont out into a new module, behind a
polymorphic interface (done by ad-hoc explicit vtable management in
C). This should allow me to drop in a Pango font handling module in
parallel with the existing one, meaning that GTK2 PuTTY will be able
to seamlessly switch between X11 server-side fonts and Pango client-
side ones as the user chooses, or even use a mixture of the two
(e.g. an X11 font for narrow characters and a Pango one for wide
characters, or vice versa).

In the process, incidentally, I got to the bottom of the `weird bug'
mentioned in the old do_text_internal(). It's not a bug in
gdk_draw_text_wc() as I had thought: it's simply that GdkWChar is a
32-bit type rather than a 16-bit one, so no wonder you have to
specify twice the length to find all the characters in the string!
However, there _is_ a bug in GTK2's gdk_draw_text_wc(), which causes
it to strip off everything above the low byte of each GdkWChar,
sigh. Solution to both problems is to use an array of the underlying
Xlib type XChar2b instead, and pass it to gdk_draw_text() cast to
gchar *. Grotty, but it works. (And it'll become significantly less
grotty if and when we have to stop using the GDK font handling
wrappers in favour of going direct to Xlib.)

Fix a cursor positioning infelicity.

it, generating plenty of scrollback, and eventually I `less' a file.
`less' switches to the alt screen. Then I want more vertical space

the saved _cursor position_ is still at line 24, not at the bottom
of the new terminal where the prompt it goes with has moved to.

positions as well as the normal cursor position.

My changes in r7738 (O_NONBLOCK for Unix Plink) were half-arsed, and
completely broke interactive logins.  The problem, or at least one of the
problems, was that in interactive use stdin, stdout, and stderr tend to be
the same file, so setting O_NONBLOCK on the latter two also sets it on the
former.  Thus, we need to cope with all of them being non-blocking.

16 years agostdout and stderr should be made O_NONBLOCK so that we don't end up blocking
Ben Harris [Mon, 24 Sep 2007 19:26:08 +0000 (19:26 +0000)]
stdout and stderr should be made O_NONBLOCK so that we don't end up blocking
the entire process because stdout is busy.

Arguably, this shouldn't apply to stderr when we're printing our own error
messages to it, but I'll leave that fix for another time.

16 years agoAdd support for automatically tuning the SSH-2 window size for decent
Ben Harris [Mon, 24 Sep 2007 15:18:11 +0000 (15:18 +0000)]
Add support for automatically tuning the SSH-2 window size for decent
performance.  The theory behind this is fairly simple, though the
implementation turns out to be a little trickier than it looks.

The basic idea is that when the connection isn't being limited by our ability
to process data, we want to ensure that the window size _as seen by the server_
never drops to zero.  Measuring the server's view of the window size is done
by arranging for it to acknowledge every SSH_MSG_CHANNEL_WINDOW_ADJUST, or
rather an SSH_MSG_CHANNEL_REQUEST sent just before it.  That way we can tell
when it its outgoing data stream it received the window adjustment, and
thus how small the server's view of the window got.

At present, we only ever increase the window size.  In theory, we could
arrange to reduce it again if the server's view of it seemed to be persistently
too large, but my experiments suggest that getting this right will be tricky.

Don't try SSH-1 RSA authentication unless the server has advertised support
for it.  It's possible that this obsoletes BUG_CHOKES_ON_RSA.  Certainly
the one SSH-1.5-Cisco-1.25 server I found was correctly not advertising RSA
auth.  For now, leave it in, because I'm not feeling entirely confident.
