| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * If stdin in the client is enable immediately, tmux will eat anythingNicholas Marriott2012-09-03
| | | | | | | | | | | | | | sent to stdin before it is needed, which can be inconvenient (eg pasting commands). Instead, start with stdin disabled and reuse MSG_STDIN from server->client to mean that stdin should be enabled. Based on a diff from Chris Johnsen.

| * Add a skeleton mode to tmux (called "control mode") that let's tmuxNicholas Marriott2012-06-18
| | | | | | | | | | | | | | commands be sent and output received on stdout. This can be used to integrate with other terminal emulators and should allow some other things to be made simpler later. More to come so doesn't do much yet and deliberately not documented.
| * Simplify logging and just fprintf(stderr, ...) for early errors.Nicholas Marriott2012-05-25

| * Instead of passing stdin/stdout/stderr file descriptors over imsg andNicholas Marriott2012-05-21
| | | | | | | | | | | | | | | | | | | | | | handling them in the server, handle them in the client and pass buffers over imsg. This is much tidier for some upcoming changes and the performance hit isn't critical. The tty fd is still passed to the server as before. This bumps the tmux protocol version so new clients and old servers are incompatible.

| * 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.
| * Add a -P option to detach to HUP the client's parent process (usuallyNicholas Marriott2011-03-03
| | | | | | | | causing it to exit as well).
| * 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").
| * 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.
| * Can't call event_del() without event_set() first - so call event_set()Nicholas Marriott2010-08-23
| | | | | | | | when setting up the client.
| * MSG_EXIT can now have a return code in the message, so check for thatNicholas Marriott2010-08-22
| | | | | | | | size as well. Stops the client fatal()ing on exit.
| * Send all three of stdin, stdout, stderr from the client to the server, so thatNicholas Marriott2010-06-28
| | | | | | | | | | | | | | | | commands can directly make use of them. This means that load-buffer and save-buffer can have "-" as the file to read from stdin or write to stdout. This is a protocol version bump so the tmux server will need to be restarted after upgrade (or an older client used).
| * Fix problems with window sizing seen by Raghavendra D Prabhu whenNicholas Marriott2010-06-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | starting tmux from .xinitrc. One of the very few things the server relies on the client for now is to pass through a message on SIGWINCH, but there is a condition where potentially a SIGWINCH may be lost during the transition from unattached (main.c) to attached (client.c). So trigger a size change immediately after the client installs its SIGWINCH handler. Also, when the terminal is resized, reset the scroll region and cursor position. Previously, we were clearing our saved idea of these, but in fact some terminals do not reset them on resize, so this caused problems during redraw. While here make a resize to the same size not cause a redraw and rename the tmux.out output log file to include the tmux PID.
| * This ioctl(TIOCGWINSZ) call is no longer necessary, the result is neverNicholas Marriott2010-06-05
| | | | | | | | used and the server now does it later on the tty fd directly.
| * Catch SIGHUP and terminate if running as a client. This prevents clientsJoel Sing2010-05-12
| | | | | | | | | | | | | | from being left hanging around when, for example, a SSH session is disconnected. ok nicm@
| * 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.
| * 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...
| * Remove a couple of unused arguments where possible, and add /* ARGSUSED */ toNicholas Marriott2009-11-26
| | | | | | | | the rest to reduce lint output.
| * imsg_read returns ssize_t not int, pointed out by lint via deraadt.Nicholas Marriott2009-11-13
| |
| * Don't return 1 unless there was actually a problem (signal/lost server) ratherNicholas Marriott2009-11-10
| | | | | | | | than for all events (normal exit/detach/etc).
| * Move some common code into a function.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.
| * Leftover unused variable :-/.Nicholas Marriott2009-11-02
| |
| * There isn't much point in doing lstat before connect so instead just do connectNicholas Marriott2009-11-02
| | | | | | | | and handle ENOENT from it which is a little tidier.
| * Clear signal flags /before/ taking action and continue afterwards to reduceNicholas Marriott2009-10-26
| | | | | | | | chance of dropping signals. Pointed out by deraadt@.
| * Tidy identify message send into a separate function.Nicholas Marriott2009-10-21
| |
| * Client tidying: get rid of client_ctx struct in favour of two variables inNicholas Marriott2009-10-21
| | | | | | | | client.c, and move the functions in client-fn.c into other files.
| * Do this in a better way - print messages when exiting with nonzero.Nicholas Marriott2009-10-13
| | | | | | | | | | Also remove the login shell information from server-info, only the client should care about it.
| * Don't print exit messages when used as a login shell, requested by martynas@ aNicholas Marriott2009-10-13
| | | | | | | | while back.
| * Support -c like sh(1) to execute a command, useful when tmux is a loginNicholas Marriott2009-09-23
| | | | | | | | | | | | | | shell. Suggested by halex@. This includes another protocol version increase (the last for now) so again restart the tmux server before upgrading.
| * Remove the internal tmux locking and instead detach each client and run theNicholas Marriott2009-09-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | command specified by a new option "lock-command" (by default "lock -np") in each client. This means each terminal has to be unlocked individually but simplifies the code and allows the system password to be used to unlock. Note that the set-password command is gone, so it will need to be removed from configuration files, and the -U command line flag has been removed. This is the third protocol version change so again it is best to stop the tmux server before upgrading.
| * Trim some code by moving the ioctl(TIOCGWINSZ) after SIGWINCH from the clientNicholas Marriott2009-09-23
| | | | | | | | | | | | | | into the server. This is another (the second of four) protocol version changes coming this morning, so again the server should be killed before upgrading.
| * Don't attempt to open() the tty path, rely on the client sending its stdin fdNicholas Marriott2009-09-23
| | | | | | | | | | | | | | | | | | with imsg and fatal if it doesn't, then set the FD_CLOEXEC flag in tty_init instead of tty_open to prevent them leaking into child processes if any are created between the two calls. This bumps the protocol version, so the tmux server should be killed before upgrading.
| * Regularise some fatal messages.Nicholas Marriott2009-09-20
