guenther 896c1da7da Use <fcntl.h> instead of <sys/file.h> for open() and friends. 
Delete a bunch of unnecessary #includes and sort to match style(9)
while doing the above cleanup.

nicm d17c90583a Prefer PWD for current directory if present in client, from Wei Zhao in 
GitHub issue 1183.
 2018-01-01 11:19:08 +00:00
nicm b20a00f93e Report better error from server when socket create fails, GitHub issue 
1201.
 2017-12-19 15:00:39 +00:00
nicm 62144b9f57 Do not try to put more in command message than will fit when sending 
(the server will treat as a fatal error). GitHub issue 1200.
 2017-12-18 22:13:36 +00:00
nicm 932f6cfbfc Because ignore SIGCHLD early, letting signal_del restore it doesn't work 
correctly, so set it explicitly back to default (and the others for good
measure).
 2017-07-14 18:49:07 +00:00
nicm 0453ad0146 Move signal code into proc.c. 2017-07-12 09:24:17 +00:00
nicm ed3cfaafb2 Make shell_command a global like other stuff rather than making it an 
exception and using callback argument.
 2017-07-12 09:21:25 +00:00
nicm 85338bb75f Add support for custom command aliases, this is an array option which 
contains items of the form "alias=command". This is consulted when an
unknown command is parsed.
 2017-01-24 19:53:37 +00:00
nicm 98e7fbb2ac Open /dev/ptm before pledge() and save it to be used for PTMGET later 
(this means inlining forkpty()).

nicm 46572ba904 Print error rather than fatal() if tcgetattr() fails, which is much more 
useful to user.

nicm ef15b4195f Revert WIP parts of previous I didn't mean to commit yet. 2017-01-16 14:52:25 +00:00
nicm 68db958477 getopt() has a struct option so just return to using options_entry. 2017-01-16 14:49:14 +00:00
nicm 95950bf668 Add -E to detach-client to exec a command to replace the client instead 
of exiting it, useful if tmux wasn't exec'd itself. From Jenna Magius.
 2017-01-13 10:12:12 +00:00
nicm 1b31d148c9 Remove some dead code in cmd-move-window.c and make a load of local 
functions static.

nicm 995af0e2b7 I no longer use my SourceForge address so replace it. 2016-01-19 15:59:12 +00:00
nicm ac8678aefe Don't print error if none to print. 2015-11-25 07:58:55 +00:00
nicm 3ff46b2e43 Shell command from -c doesn't have to be global, pass it as an argument. 2015-11-24 23:22:51 +00:00
nicm dca93c56e0 Do lock failures slightly better, return a special value so we don't 
unlink the wrong thing.
 2015-11-24 23:01:51 +00:00
nicm 73e30cbda8 Actually show something (even if it not that helpful) if the server 
fails to start (for example if it can't create the socket), rather than
hanging or showing nothing.
 2015-11-24 22:45:44 +00:00
nicm c913fb99b6 Tidy the code that works out the socket path, and just use the full path 
in the global socket_path rather than copying it.
 2015-11-24 22:27:22 +00:00
nicm bef217b241 Switch a fprintf to a fatal, and wrap some long lines. 2015-11-24 22:04:36 +00:00
nicm 577c0e3e5a Use __unused rather than rolling our own. 2015-11-18 14:27:44 +00:00
nicm a582b62287 Accidentally turned off pledge, turn it back on. 2015-11-15 14:32:48 +00:00
nicm c56b81a2ce Push stdout and stderr to clients more aggressively, and add an event to 
continue if the send fails.
 2015-11-14 09:41:06 +00:00
nicm b0a99e85b6 Don't shift version out of peerid, it is needed later. 2015-10-31 13:43:38 +00:00
nicm 01defc9f49 Because pledge(2) does not allow us to pass directory file descriptors 
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).
 2015-10-31 08:13:58 +00:00
nicm bf9c933cae Like options, move the environ struct into environ.c. 2015-10-28 09:51:55 +00:00
nicm 44657bf932 Move struct options into options.c. 2015-10-27 15:58:42 +00:00
nicm 07b0ea03c3 Break the common process set up, event loop and imsg dispatch code 
between server and client out into a separate internal API. This will
make it easier to add another process.
 2015-10-27 13:23:24 +00:00
nicm 174a2ad731 Pass current directory as a string rather than a file descriptor because 
pledge doesn't let us pass directory file descriptors.
 2015-10-18 20:42:42 +00:00
nicm 9c601ebde8 Add pledge "stdio unix sendfd proc exec tty" to tmux client process, 
"sendfd" is dropped after first message from the server.

guenther 241fd72f75 Userspace doesn't need to use SUN_LEN(): connect() and bind() must accept 
sizeof(struct sockaddr_un), so do the simple, portable thing

nicm 2a62917444 Don't leak fd and path on failure. 2015-09-24 12:06:20 +00:00
nicm 67ee995cc1 No need to keep global options around for client which doesn't use them. 2015-09-09 12:09:21 +00:00
nicm c6e9160c67 Login shell can be a client flag, and move the exec code into client.c. 2015-08-30 22:40:25 +00:00
nicm dd92b6e83d Event base does not need to be global. 2015-08-30 22:19:07 +00:00
nicm 4e637b1b61 Ignore environment variables that are too long to send to the server. 2015-07-13 18:10:26 +00:00
nicm 29c29e7717 Add a format for client PID (client_pid) and server PID (pid). Diff for 
client_pid from Thomas Adam.
 2015-06-14 10:07:44 +00:00
nicm 6b2129696f Move the nested check from client to server and compare the client tty 
name to all the pane pty names instead of comparing socket paths. This
means that "new -d" will work without unsetting $TMUX.

nicm a5a873dccc Set up signal handler earlier so that we don't get zombies, reported by 
sobrado@.

nicm 900f6fc17e Tidy up some includes. 2014-10-20 23:27:14 +00:00
nicm 045d0c3b9f Call waitpid on SIGCHLD even if client not attached, it is possible (on 
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.
 2014-10-01 23:23:19 +00:00
nicm 4e956d545a Various minor style and spacing nits. 2014-09-01 21:50:18 +00:00
nicm 8e4ae12b4d lockf is entirely useless and it was a mistake to change to it, go back 
to using flock which actually works sensibly. Also always retry the lock
to fix a potential race, and add some extra logging.
