From 52e3628c3edd98ae3402605e7f44a0fc4545dd0a Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Thu, 1 May 2008 19:51:05 +0000 Subject: Yes, yet another evil all-in-one commit of intervowen changes. I suck. * Drop "state" directory, fold that into "runtime directory" * No longer automatically rewind when a new stream connects * Rework sound file stream, to cause a rewind on initialisation, shorten _pop() code a bit * Fix reference counting of pa_socket_server in the protocol implementations * Rework daemon initialization code to be compatible with non-SUID-root setups where RLIMIT_RTPRIO is non-zero * Print warning if RT/HP is enabled in the config, but due to missing caps, rlimits, policy we cannot enable it. * Fix potential memory leak in pa_open_config_file() * Add pa_find_config_file() which works much like pa_open_config_file() but doesn't actually open the config file in question. Just searches for it. * Add portable pa_is_path_absolute() * Add pa_close_all() and use it on daemon startup to close leaking file descriptors (inspired from what I did for libdaemon) * Add pa_unblock_sigs() and use it on daemon startup to unblock all signals (inspired from libdaemon, too) * Add pa_reset_sigs() and use it on daemon startup to reset all signal handlers (inspired from libdaemon as well) * Implement pa_set_env() * Define RLIMIT_RTTIME and friends if not defined by glibc * Add pa_strempty() * rename state testing macros to include _IS_, to make clearer that they are no states, but testing macros * Implement pa_source_output_set_requested_latency_within_thread() to be able to forward latency info to sources from within the IO thread * Similar for sink inputs * generelize since_underrun counter in sink inputs to "playing_for" and "underrun_for". Use only this for ignore potential rewind requests over underruns * Add new native protocol message PLAYBACK_STREAM_MESSAGE_STARTED for notification about the end of an underrun * Port native protocol to use underrun_for/playing_for which is maintained by the sink input anyway * Pass underrun_for/playing_for in timing info to client * Drop pa_sink_skip() since it breaks underrun detection code * Move PID file and unix sockets to the runtime dir (i.e. ~/.pulse). This fixes a potention DoS attack from other users stealing dirs in /tmp from us so that we cannot take them anymore) * Allow setting of more resource limits from the config file. Set RTTIME by default * Streamline daemon startup code * Rework algorithm to find default configuration files * If run in system mode use "system.pa" instead of "default.pa" as default script file * Change ladspa sink to use pa_clamp_samples() for clamping samples * Teach module-null-sink how to deal with rewinding * Try to support ALSA devices with no implicit channel map. Synthesize one by padding with PA_CHANNEL_POSITION_AUX channels. This is not tested since I lack hardware with these problems. * Make use of time smoother in the client libraries. * Add new pa_stream_is_corked() and pa_stream_set_started_callback() functions to public API * Since our native socket moved, add some code for finding sockets created by old versions of PA. This should ease upgrades git-svn-id: file:///home/lennart/svn/public/pulseaudio/branches/glitch-free@2329 fefdeb5f-60dc-0310-8127-8f9354f1896f --- src/pulse/stream.h | 15 +++++++++++++-- 1 file changed, 13 insertions(+), 2 deletions(-) (limited to 'src/pulse/stream.h') diff --git a/src/pulse/stream.h b/src/pulse/stream.h index 69943a70..ebb45f2b 100644 --- a/src/pulse/stream.h +++ b/src/pulse/stream.h @@ -339,6 +339,10 @@ const char *pa_stream_get_device_name(pa_stream *s); * server is older than 0.9.8. \since 0.9.8 */ int pa_stream_is_suspended(pa_stream *s); +/** Return 1 if the this stream has been corked.
