Stick line length to what is actually used (removing an optimization that
allowed it to be bigger), and use clear line/EOL sequences rather than spaces
in copy/scroll mode.
This fixes xterm copy/paste from tmux which treats trailing spaces differently
from clearing a line with the escape sequences. Reported by martynas@.
Fix a race condition when asking a client to take over the terminal (switching
to a different poll loop):
If a MSG_READY was followed very quickly by a MSG_EXIT (for example if doing
"tmux new 'exit'"), both messages could be read as part of the same imsg_read
in the first client poll loop. The MSG_READY would then cause a switch to the
second client loop, which would immediately call poll(2) again, causing the
client to hang forever waiting for an exit message that it already had.
Change to call imsg_get to process any existing messages before polling.
use the error and exit on MSG_EXIT (it was being handled in the default
case). Undo the last change, move the errstr check into the MSG_EXIT case, and
add a comment.
When using tmux as a login shell, there is currently no way to specify a shell
to be used as a login shell inside tmux, so add a default-shell session option.
This sets the shell invoked as a login shell when the default-command option is
empty.
The default option value is whichever of $SHELL, getpwuid(getuid())'s pw_shell
or /bin/sh is valid first.
Based on a diff from martynas@, changed by me to be a session option rather
than a window option.
Use "Password:" with no space for password prompts and don't display a *s for
the password, like pretty much everything else. From martynas@ with minor
tweaks by me.
Add a new display-panes command, with two options (display-panes-colour and
display-panes-time), which displays a visual indication of the number of each
pane.
Don't call tty_free unless the client is a terminal, otherwise tty_init hasn't
been called and it may end up doing close(0). From Kalle Olavi Niemitalo.
Add a choose-client command and extend choose-{session,window} to accept a
template. After a choice is made, %% (or %1) in the template is replaced by the
name of the session, window or client suitable for -t and the result executed
as a command. So, for example, "choose-window "killw -t '%%'"" will kill the
selected window.
The defaults if no template is given are (as now) select-window for
choose-window, switch-client for choose-session, and detach-client for
choose-client (now bound to D).
