Simplify the way jobs work and drop the persist type, so all jobs are
fire-and-forget.
Status jobs now managed with two trees of output (new and old), rather
than storing the output in the jobs themselves. When the status line is
processed any jobs which don't appear in the new tree are started and
the output from the old tree displayed. When a job finishes it updates
the new tree with its output and that is used for any subsequent
redraws. When the status interval expires, the new tree is moved to the
old so that all jobs are run again.
This fixes the "#(echo %H:%M:%S)" problem which would lead to thousands
of identical persistent jobs and high memory use (this can still be
achieved by adding "sleep 30" but that is much less likely to happen by
accident).

Use LIST_* not SLIST_*.

Set $TMUX without the session when background jobs are run.

Move all calls to fcntl(...O_NONBLOCK) into a function and clear the
flag on the stdio file descriptors before closing them (fixes things
like "tmux ls && cat").

Trying to set FD_CLOEXEC on every fd is a lost cause, just use
closefrom() before exec.

Do not call event_del() for signals after fork(), just use sigaction()
directly instead - calling libevent functions after fork() w/o
event_reinit() is a bad idea, even if in this case it was harmless.

Make signal handler setup/teardown two common functions instead of six,
and reset SIGCHLD after fork to fix problems with some shells. From
Romain Francoise.

modified with setenv -g) rather than with the environment tmux started
with.

Typo fix from Tim van der Molen.

Massive spaces->tabs and trailing whitespace cleanup, hopefully for the last
time now I've configured emacs to make them displayed in really annoying
colours...

Remove a couple of unused arguments where possible, and add /* ARGSUSED */ to
the rest to reduce lint output.
|

Add back JOB_PERSIST checks that got lost.

Switch jobs over to use a bufferevent.

Initial changes to move tmux to libevent.
This moves the client-side loops are pretty much fully over to event-based only
(tmux.c and client.c) but server-side (server.c and friends) treats libevent as
a sort of clever poll, waking up after every event to run various things.
Moving the server stuff over to bufferevents and timers and so on will come
later.

Add a flag for jobs that shouldn't be freed after they've died and use it for
status jobs, then only kill those jobs when status-left, status-right or
set-titles-string is changed.
Fixes problems with changing options from inside #().
|
| |
|
|
|
| |
Remove unused function.
|
| |
|

recommended. DOH.
|
| |
|
|
|
| |
Switch run-shell over to queue the command in the background like #().
|
| |
|
|
|
|
|
| |
There isn't much point in having a free function if it isn't used.
Also allow a NULL tree.
|

|

Collect status from dead jobs and don't invoke the callback until both
all input (the socket is closed) and status is available.
|
| |
|
|
|
|
| |
Put all jobs on a global all_jobs list and use that in server.c instead of
running through all the clients.
|

Rather than running status-left, status-right and window title #() with popen
immediately every redraw, queue them up and run them in the background,
starting each once every status-interval. The actual status line uses the
output from the last run.
This brings several advantages:
- tmux itself may be called from inside #() without causing the server to hang;
- likewise, sleep or similar doesn't cause the server to block;
- commands aren't run excessively often when redrawing;
- commands shared by status-left and status-right, or used multiple times, will
only be run once.
run-shell and if-shell still use system()/popen() but will be changed over to
use this too later.
