* Rename global configuration define.Nicholas Marriott2013-04-24

* Add a command queue to standardize and simplify commands that call otherNicholas Marriott2013-03-24
| | | | | | | | | | | | | | | | | | | | | | commands and allow a command to block execution of subsequent commands. This allows run-shell and if-shell to be synchronous which has been much requested. Each client has a default command queue and commands are consumed one at a time from it. A command may suspend execution from the queue by returning CMD_RETURN_WAIT and then resume it by calling cmd_continue() - for example run-shell does this from the callback that is fired after the job is freed. When the command queue becomes empty, command clients are automatically exited (unless attaching). A callback is also fired - this is used for nested commands in, for example, if-shell which can block execution of the client's cmdq until a new cmdq becomes empty. Also merge all the old error/info/print functions together and lose the old curclient/cmdclient distinction - a cmdq is bound to one client (or none if in the configuration file), this is a command client if c->session is NULL otherwise an attached client.

* xfree is not particularly helpful, remove it. From Thomas Adam.Nicholas Marriott2012-07-10

* Stop accepting new clients for 1 second on EMFILE/ENFILE. Based onNicholas Marriott2012-04-11
| | | | ongoing fixes to other daemons by Theo.
* Use a lock file and flock() to serialize server start, avoids problemsNicholas Marriott2012-03-09
| | | | | when running a bunch of tmux from cron at the same time. Based on a diff from Tim Ruehsen.
* Give each pane created in a tmux server a unique id (starting from 0),Nicholas Marriott2011-03-27
| | | | | put it in the TMUX_PANE environment variable and accept it as a target. Suggested by and with testing and tweaks from Ben Boeckel.
* Use LIST_* not SLIST_*.Nicholas Marriott2011-01-26
|
* Move all calls to fcntl(...O_NONBLOCK) into a function and clear theNicholas Marriott2011-01-08
| | | | | flag on the stdio file descriptors before closing them (fixes things like "tmux ls && cat").
* Don't reset the activity timer for unattached sessions every second,Nicholas Marriott2011-01-01
| | | | | | | this screws up the choice of most-recently-used. Instead, break the time update into a little function and do it when the session is attached. Pointed out by joshe@.
* Change from a per-session stack of buffers to one global stack which isNicholas Marriott2010-12-30
| | | | | | | much more convenient and also simplifies lot of code. This renders copy-buffer useless and makes buffer-limit now a server option. By Tiago Cunha.
* Store sessions in an RB tree by name rather than a list, this is tidierNicholas Marriott2010-12-21
| | | | | | | | | and allows them to easily be shown sorted in various lists (list-sessions/choose-sessions). Keep a session index which is used in a couple of places internally but make it an ever-increasing number rather than filling in gaps with new sessions.
* Merge the before and after attach client code into one in client.cNicholas Marriott2010-10-18
| | | | (instead of two in tmux.c and client.c).
* Trying to set FD_CLOEXEC on every fd is a lost cause, just useNicholas Marriott2010-10-16
| | | | closefrom() before exec.
* Two new options:Nicholas Marriott2010-09-26
| | | | | | | | | | | | - server option "exit-unattached" makes the server exit when no clients are attached, even if sessions are present; - session option "destroy-unattached" destroys a session once no clients are attached to it. These are useful for preventing tmux remaining in the background where it is undesirable and when using tmux as a login shell to keep a limit on new sessions.
* Modify the permissions on the socket when adding or removing +x to showNicholas Marriott2010-09-26
| | | | attached sessions, rather than replacing them.
* Do not call event_del() for signals after fork(), just use sigaction()Nicholas Marriott2010-08-19
| | | | | directly instead - calling libevent functions after fork() w/o event_reinit() is a bad idea, even if in this case it was harmless.
* switch back to kqueue for now, since (a) kqueue has been fixed to dealTheo Deraadt2010-08-04
| | | | | | with strange devices and (b) since there appears to be a bull in the poll code in libevent as well... requested by nicm who is away
* kqueue(2) is currently broken when used with /dev/null and a few otherNicholas Marriott2010-07-24
| | | | | | | | devices. An upcoming fix for some problems with the client stdout/stderr handling relies on it working, so make tmux force libevent to use poll(2) via EVENT_NOKQUEUE, until we have fixed kqueue.
* Give tmux sockets (but not the containing folder) groupNicholas Marriott2010-06-21
| | | | | permissions. This allows hardlinks to the sockets to be used more easily.
* Put this back in with the initialisation in the right order.Nicholas Marriott2010-05-04
|
* Revert last change, it appears to be broken somehow.Nicholas Marriott2010-05-04
|
* Make signal handler setup/teardown two common functions instead of six,Nicholas Marriott2010-05-03
| | | | | and reset SIGCHLD after fork to fix problems with some shells. From Romain Francois.
* Merge copy mode and output mode, dropping the latter. Idea and code fromNicholas Marriott2010-04-06
| | | | Micah Cowan.
* Nuke unused variable.Nicholas Marriott2010-03-22
|
* Use the array.h code for the causes list.Nicholas Marriott2010-02-06
|
* Instead of bailing out on the first configuration file error, carry on,Nicholas Marriott2010-02-06
| | | | | collecting all the errors, then start with the active window in more mode displaying them.
* Ignore SIGHUP as well.Nicholas Marriott2010-01-30
|
* Massive spaces->tabs and trailing whitespace cleanup, hopefully for the lastNicholas Marriott2009-12-03
| | | | | time now I've configured emacs to make them displayed in really annoying colours...
* Close the pane if the process died due to a signal, not just if it exitedNicholas Marriott2009-12-02
| | | | normally.
* Remove a couple of unused arguments where possible, and add /* ARGSUSED */ toNicholas Marriott2009-11-26
| | | | the rest to reduce lint output.
* Destroy panes immediately rather than checking them all every loop.Nicholas Marriott2009-11-13
|
* Free the pane bufferevent when the fd is closed (the signal could come beforeNicholas Marriott2009-11-11
| | | | the error callback).
* Only need to chmod +x or -x the socket when a client is created, lost orNicholas Marriott2009-11-11
| | | | attached, rather than every event loop.
* EVLOOP_ONCE takes care of the wakeup, so no need to call event_loopexit(NULL).Nicholas Marriott2009-11-05
|
* Now all timers are events, there is no longer any need to wake up every 50 ms -Nicholas Marriott2009-11-05
| | | | only wake up when an event happens.
* Move status timer check into the global once-per-second timer, this could maybeNicholas Marriott2009-11-04
| | | | be done better but one every second is better than once every 50 ms.
* Don't reenlist the client imsg event every loop, instead have a small functionNicholas Marriott2009-11-04
| | | | to it and call it after the event triggers or after a imsg is added.
* Tell the client to exit on configuration file error.Nicholas Marriott2009-11-04
|
* Convert the window pane (pty master side) fd over to use a bufferevent.Nicholas Marriott2009-11-04
| | | | | The evbuffer API is very similar to the existing tmux buffer API so this was remarkably painless. Not many possible ways to do it, I suppose.
* Call event_init() before loading the config file, since potentially it couldNicholas Marriott2009-11-04
| | | | set up events.
* Switch jobs over to use a bufferevent.Nicholas Marriott2009-11-04
|
* Initial changes to move tmux to libevent.Nicholas Marriott2009-11-04
| | | | | | | | | 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.
* Change session and client activity and creation time members to have moreNicholas Marriott2009-11-03
| | | | | | | | meaningful names. Also, remove the code to try and update the session activity time for the command client when a command message is received as is pointless because it des not have a session.
* Reorder slightly to tidy code.Nicholas Marriott2009-11-02
|
* Move the poll registration functions into the server-*.c files.Nicholas Marriott2009-10-27
|
* tabs are better; ok nicmTheo Deraadt2009-10-26
|
* Clear signal flags /before/ taking action and continue afterwards to reduceNicholas Marriott2009-10-26
| | | | chance of dropping signals. Pointed out by deraadt@.
