2372b0fdc6 Add a flag to make a client wait for an empty line before exiting in 
control mode to avoid stray commands ending up in the shell.

a54a88edd6 Instead of sending all data to control mode clients as fast as possible, 
add a limit of how much data will be sent to the client and try to use
it for panes with some degree of fairness. GitHub issue 2217, with
George Nachman.

dceb6a15d0 Add a -D flag to ask tmux not to daemonize, useful both for running a 
debugger (lldb does not have follow-fork-mode) and for running with a
managed supervisor init system. GitHub issue 2190.

every command that is run.

2a5702a936 When the server socket is given by the user with -S, create it with 
umask 177 instead of 117 because it may not be in a safe directory like
the default directory in /tmp. The user can chmod it more open after it
is created if they want.

ae541287d3 Expand command formats in %if and move the config file loading later (to 
when the first client has identified) so all the client formats are
available, fixes problems reported by Thomas Sattler.

e37f34facc Do not load the config file if the server is exiting because it failed 
to start, otherwise commands like lsk which start the server again can
end up looping infinitely. Also make the first client exit
correctly. Problem reported by Wael M Nasreddine.

19f3a5c612 Add a missing client-detached hook when the server shuts down, and do 
not exit until jobs started from run-shell/if-shell have finished (add a
job flags member and a flag to indicate other jobs). GitHub issue 1245.

932f6cfbfc Because ignore SIGCHLD early, letting signal_del restore it doesn't work 
correctly, so set it explicitly back to default (and the others for good
measure).

51112221ee Block signals between forking and clearing signal handlers (or calling 
event_reinit) - if the child gets a signal and fires the libevent signal
handler during this period it could write a signal into the parent's
signal pipe. GitHub issue 1001 from Aaron van Geffen.

adf5628087 Support SIGUSR2 to stop and start logging for an existing server. Also 
we currently only have two log levels so just use -v and -vv rather than
-v and -vvvv, and clarify the man page entry for -v.

efaf4c16cf Make the cmd_find_* functions more obvious when looking for a client, 
rather than having it inside other functions. Should be no change to the
way targets are resolved just yet.

428be9803c History needs to be loaded after config parsing is done - now that 
commands are queued, that's in cfg_done not after start_cfg finishes.

0b44ad99b5 If a #() command doesn't exit, use its most recent line of output (it 
must be a full line). Don't let it redraw the status line more than once
a second.

c6a3446398 Instead of numbering session groups, give them a name which may be given 
to -t instead of a target session. Also allow them to contain only one
session.

026ad08b56 Notifys can go via the command queue instead of using their own queue. 2016-10-16 19:15:02 +00:00
nicm
ddc4512d2e Rewrite command queue handling. Each client still has a command queue, 
but there is also now a global command queue. Instead of command queues
being dispatched on demand from wherever the command happens to be
added, they are now all dispatched from the top level server
loop. Command queues may now also include callbacks as well as commands,
and items may be inserted after the current command as well as at the end.

This all makes command queues significantly more predictable and easier
to use, and avoids the complex multiple nested command queues used by
source-file, if-shell and friends.

A mass rename of struct cmdq to a better name (cmdq_item probably) is
coming.

9b3ae84993 Drain notifys once at the end of the server loop instead of doing it 
from the end of every command queue (which could be nested).

fc118e13a9 tmux: only consider ACCESSPERMS for setting mode on socket_path. 
it explicitly removes any S_ISUID|S_ISGID|S_ISTXT bits, instead of letting
pledge(2) silenciously remove them.

1e2df2d464 Remove the -I part of show-messages which isn't really that useful; the 
server start time can now be accessed with a new start_time format (use:
tmux display -p '#{t:start_time}')

d6daf37df4 Tidy utf8.c a little: build table on first use, and make utf8_width take 
a u_int rather than splitting and then combining again in utf8_split.

abb4e9e2fa The output log is only useful once and it means creating a file, so open 
it once at startup instead of in every call to tty_open.

07b0ea03c3 Break the common process set up, event loop and imsg dispatch code 
between server and client out into a separate internal API. This will
make it easier to add another process.

5383b047d1 tmux can call pledge() in main with large set and then reduce it 
slightly in the server to "stdio rpath wpath cpath fattr unix recvfd
proc exec tty ps".
