* Because pledge(2) does not allow us to pass directory file descriptorsnicm2015-10-311-3/+5
| | | | | | | | | around, we can't use file descriptors for the working directory because we will be unable to pass it to a privileged process to tell it where to read or write files or spawn children. So move tmux back to using strings for the current working directory. We try to check it exists with access() when it is set but ultimately fall back to ~ if it fails at time of use (or / if that fails too).

* Call waitpid on SIGCHLD even if client not attached, it is possible (onnicm2014-10-011-9/+5
| | | | | very slow platforms) for the first daemon() child to still be running when client_attached is set so we end up with a zombie. From J Raynor.
* Various minor style and spacing nits.nicm2014-09-011-3/+3

* 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.
* from nicm: : handle msgbuf_write() returning EAGAINbenno2013-11-131-2/+2

* We accidentally haven't been using $TMUX to work out the session for anicm2013-10-101-5/+1
| | | | | | while and in fact it is less useful that using the client ttyname. So don't bother and don't pass it from the client. If we need it in future it is in c->environ.
* Show session name in detached message. Requested by somebody a fewnicm2013-10-101-4/+19

* 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.

* Rename session idx to session id throughout and add $ prefix to targetsnicm2013-03-251-2/+2

* Send DSC 1000p at the beginning of a -CC client's lifetime and ST andnicm2013-03-251-2/+10
| | | | the end, from George Nachman.
* 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.

* If stdin in the client is enable immediately, tmux will eat anythingnicm2012-09-031-2/+7
| | | | | | | 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.
