* set the close-on-exec flag on all file descriptorsMax Kellermann2009-11-071-5/+2
| | | | | | | | | | | Added the "fd_util" library, which attempts to use the new thread-safe Linux system calls pipe2(), accept4() and the options O_CLOEXEC, SOCK_CLOEXEC. Without these, it falls back to FD_CLOEXEC, which is not thread safe. This is particularly important for the "pipe" output plugin (and others, such as JACK/PulseAudio), because we were heavily leaking file descriptors to child processes.
* client, event_pipe: explicitly ignore the write() resultMax Kellermann2009-04-011-1/+1
| | | | | | | | | | On both locations, the result of write() can be ignored safely. In event_pipe_emit_fast(), that can only be "EAGAIN", which means that the pipe buffer is full - no further notification required. In client_init(), that would be a fatal connection error, which would be caught by the next event. This patch fixes gcc warnings.
* event_pipe can only be non-blocking if !WIN32Sean McNamara2009-03-271-0/+2

* all: Update copyright header.Avuton Olrich2009-03-131-8/+7
| | | | | | | | This updates the copyright header to all be the same, which is pretty much an update of where to mail request for a copy of the GPL and the years of the MPD project. This also puts all committers under 'The Music Player Project' umbrella. These entries should go individually in the AUTHORS file, for consistancy.
* added G_LOG_DOMAIN macros to several librariesMax Kellermann2009-02-191-0/+3
| | | | | Define the GLib logging domain in the following libraries: conf, daemon, event_pipe, log.
* event_pipe: remove the GLib source from the main contextMax Kellermann2009-01-101-1/+5
| | | | Free memory before exiting.
* event_pipe: removed the unused function event_pipe_wait()Max Kellermann2009-01-041-14/+4
|
* utils: removed unused functionsMax Kellermann2009-01-031-0/+3
| | | | | Removed all allocation functions, xwrite(), xread(), ARRAY_SIZE(). Those have been superseded by GLib.
* event_pipe: use GLib loggingMax Kellermann2009-01-031-2/+3
|
* event_pipe: use close() instead of xclose()Max Kellermann2009-01-031-3/+2
| | | | | xclose() aims to be the signal safe version of close(). However during cleanup, this isn't important.
* event_pipe: use _pipe() on WIN32Max Kellermann2009-01-031-2/+13
| | | | | Windows has no pipe(), it only has _pipe() with two additional parameters.
* event_pipe: moved variable "main_task" to main.cMax Kellermann2009-01-031-5/+0
|
* event_pipe: replaced PIPE_EVENT_SIGNAL with main_notifyMax Kellermann2009-01-021-14/+4
| | | | | | There is only one location using PIPE_EVENT_SIGNAL: to synchronize player_command() with player_command_finished(). Use the "notify" library instead of the event_pipe here.
* event_pipe: added event_pipe_emit_fast()Max Kellermann2009-01-011-0/+8
| | | | | | event_pipe_emit_fast() is aimed for use in signal handlers: it doesn't lock the mutex, and doesn't log on error. That makes it potentially lossy, but for its intended use, that does not matter.
* event_pipe: added pipe_event enum and callbacksMax Kellermann2009-01-011-4/+67
| | | | | | | | | Make the event_pipe (formerly main_notify) send/receive a set of events, with a callback for each one. The default event PIPE_EVENT_SIGNAL does not have a callback. It is still there for waking up the main thread, when it is waiting for the player thread.
* event_pipe: renamed functions from main_notify_* to event_pipe_*Max Kellermann2009-01-011-12/+12
| | | | Continuing the previous patch.
* main_notify: renamed source to event_pipe.cMax Kellermann2009-01-011-0/+85
We are going to migrate away from the concept of notifying the main thread. There should be events sent to it instead. This patch starts a series to implement that.
