From baf9b94ecf3872f35717c3236a0040160ec99aef Mon Sep 17 00:00:00 2001 From: Eric Wong Date: Sat, 12 Apr 2008 09:46:11 +0000 Subject: Fix the problem of songs not advancing without client activity The select() in the main event loop blocks now (saving us many unnecessary wakeups). This interacted badly with the threads that were trying to wakeup the main task via pthread_cond_signal() since the main task was not blocked on a condition variable, but on select(). So now if we detect a need to wakeup the player, we write to a pipe which select() is watching instead of blindly calling pthread_cond_signal(). git-svn-id: https://svn.musicpd.org/mpd/trunk@7347 09075e82-0dd4-0310-85a5-a0d7c8717e4f --- src/main_notify.h | 34 ++++++++++++++++++++++++++++++++++ 1 file changed, 34 insertions(+) create mode 100644 src/main_notify.h (limited to 'src/main_notify.h') diff --git a/src/main_notify.h b/src/main_notify.h new file mode 100644 index 000000000..c7bba4440 --- /dev/null +++ b/src/main_notify.h @@ -0,0 +1,34 @@ +/* the Music Player Daemon (MPD) + * Copyright (C) 2003-2007 Warren Dukes + * Copyright (C) 2008 Eric Wong + * + * This project's homepage is: http://www.musicpd.org + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; either version 2 of the License, or + * (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
