* Call waitpid on SIGCHLD even if client not attached, it is possible (onnicm2014-10-011-9/+5

* lockf is entirely useless and it was a mistake to change to it, go backnicm2014-07-211-13/+37

* Three small changes from Tiago Cunha:nicm2014-01-091-2/+3
| | | | | | - Check for truncation when copying path. - Don't need to use a temporary buffer in screen_set_title. - Include strerror in output when connecting to server fails.

* Alter how tmux handles the working directory to internally use filenicm2013-10-101-34/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | descriptors rather than strings. - Each session still has a current working directory. - New sessions still get their working directory from the client that created them or its attached session if any. - New windows are created by default in the session working directory. - The -c flag to new, neww, splitw allows the working directory to be overridden. - The -c flag to attach let's the session working directory be changed. - The default-path option has been removed. To get the equivalent to default-path '.', do: bind c neww -c $PWD To get the equivalent of default-path '~', do: bind c neww -c ~ This also changes the client identify protocol to be a set of messages rather than one as well as some other changes that should make it easier to make backwards-compatible protocol changes in future.

* Add a command queue to standardize and simplify commands that call othernicm2013-03-241-2/+3
| | | | | | | | | | | | | | | | | | | | | | 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.

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

* Send all three of stdin, stdout, stderr from the client to the server, so thatnicm2010-06-281-3/+10
| | | | | | | | 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 whennicm2010-06-051-1/+8
| | | | | | | | | | | | | | | | | | 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.
