From 57fbede61a07780ace8600ea11c09e2bdafb3612 Mon Sep 17 00:00:00 2001 From: nicm Date: Sat, 24 Jul 2010 19:25:31 +0000 Subject: [PATCH] kqueue(2) is currently broken when used with /dev/null and a few other devices. An upcoming fix for some problems with the client stdout/stderr handling relies on it working, so make tmux force libevent to use poll(2) via EVENT_NOKQUEUE, until we have fixed kqueue. --- usr.bin/tmux/server.c | 5 ++++- usr.bin/tmux/tmux.c | 5 ++++- 2 files changed, 8 insertions(+), 2 deletions(-) diff --git a/usr.bin/tmux/server.c b/usr.bin/tmux/server.c index 88d73d73a34..4d52b888d5b 100644 --- a/usr.bin/tmux/server.c +++ b/usr.bin/tmux/server.c @@ -1,4 +1,4 @@ -/* $OpenBSD: server.c,v 1.89 2010/06/21 00:18:57 nicm Exp $ */ +/* $OpenBSD: server.c,v 1.90 2010/07/24 19:25:32 nicm Exp $ */ /* * Copyright (c) 2007 Nicholas Marriott @@ -139,8 +139,11 @@ server_start(char *path) fatal("daemon failed"); /* event_init() was called in our parent, need to reinit. */ + if (setenv("EVENT_NOKQUEUE", "1", 1) != 0) + fatal("setenv"); if (event_reinit(ev_base) != 0) fatal("event_reinit failed"); + unsetenv("EVENT_NOKQUEUE"); clear_signals(); logfile("server"); diff --git a/usr.bin/tmux/tmux.c b/usr.bin/tmux/tmux.c index 644412deaf9..d34b03186de 100644 --- a/usr.bin/tmux/tmux.c +++ b/usr.bin/tmux/tmux.c @@ -1,4 +1,4 @@ -/* $OpenBSD: tmux.c,v 1.84 2010/07/11 17:06:45 nicm Exp $ */ +/* $OpenBSD: tmux.c,v 1.85 2010/07/24 19:25:31 nicm Exp $ */ /* * Copyright (c) 2007 Nicholas Marriott @@ -532,7 +532,10 @@ main(int argc, char **argv) exit(1); } + if (setenv("EVENT_NOKQUEUE", "1", 1) != 0) + fatal("setenv"); ev_base = event_init(); + unsetenv("EVENT_NOKQUEUE"); set_signals(main_signal); /* Initialise the client socket/start the server. */ -- 2.20.1
