From 3c9f218d411024f3dfaff15b0b39b7a689a87c2f Mon Sep 17 00:00:00 2001 From: nicm Date: Sun, 11 Jul 2010 17:06:45 +0000 Subject: Return the command client return code with MSG_EXIT now that MSG_ERROR and MSG_PRINT are unused. New clients should be compatible with old tmux servers but vice versa may print an error. --- usr.bin/tmux/tmux.c | 16 +++++++++------- 1 file changed, 9 insertions(+), 7 deletions(-) (limited to 'usr.bin/tmux/tmux.c') diff --git a/usr.bin/tmux/tmux.c b/usr.bin/tmux/tmux.c index 9f80e5a0b7d..644412deaf9 100644 --- a/usr.bin/tmux/tmux.c +++ b/usr.bin/tmux/tmux.c @@ -1,4 +1,4 @@ -/* $OpenBSD: tmux.c,v 1.83 2010/06/28 22:10:42 nicm Exp $ */ +/* $OpenBSD: tmux.c,v 1.84 2010/07/11 17:06:45 nicm Exp $ */ /* * Copyright (c) 2007 Nicholas Marriott @@ -61,7 +61,6 @@ char *makesockpath(const char *); __dead void shell_exec(const char *, const char *); struct imsgbuf *main_ibuf; -int main_exitval; void main_signal(int, short, unused void *); void main_callback(int, short, void *); @@ -548,7 +547,6 @@ main(int argc, char **argv) events |= EV_WRITE; event_once(main_ibuf->fd, events, main_callback, shellcmd, NULL); - main_exitval = 0; event_dispatch(); clear_signals(); @@ -597,6 +595,7 @@ main_dispatch(const char *shellcmd) struct imsg imsg; ssize_t n, datalen; struct msg_shell_data shelldata; + struct msg_exit_data exitdata; if ((n = imsg_read(main_ibuf)) == -1 || n == 0) fatalx("imsg_read failed"); @@ -611,10 +610,13 @@ main_dispatch(const char *shellcmd) switch (imsg.hdr.type) { case MSG_EXIT: case MSG_SHUTDOWN: - if (datalen != 0) - fatalx("bad MSG_EXIT size"); - - exit(main_exitval); + if (datalen != sizeof exitdata) { + if (datalen != 0) + fatalx("bad MSG_EXIT size"); + exit(0); + } + memcpy(&exitdata, imsg.data, sizeof exitdata); + exit(exitdata.retcode); case MSG_READY: if (datalen != 0) fatalx("bad MSG_READY size"); -- cgit v1.2.3-59-g8ed1b
