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/def.h | 35 ++++++++++++++++++++++++++++++++++- 1 file changed, 34 insertions(+), 1 deletion(-) (limited to 'src/pulse/def.h') diff --git a/src/pulse/def.h b/src/pulse/def.h index 8a83d7a9..1a0b9cb6 100644 --- a/src/pulse/def.h +++ b/src/pulse/def.h @@ -48,6 +48,15 @@ typedef enum pa_context_state { PA_CONTEXT_TERMINATED /**< The connection was terminated cleanly */ } pa_context_state_t; +/** Return non-zero if the passed state is one of the connected states */ +static inline int PA_CONTEXT_IS_GOOD(pa_context_state_t x) { + return + x == PA_CONTEXT_CONNECTING || + x == PA_CONTEXT_AUTHORIZING || + x == PA_CONTEXT_SETTING_NAME || + x == PA_CONTEXT_READY; +} + /** The state of a stream */ typedef enum pa_stream_state { PA_STREAM_UNCONNECTED, /**< The stream is not yet connected to any sink or source */ @@ -57,6 +66,13 @@ typedef enum pa_stream_state { PA_STREAM_TERMINATED /**< The stream has been terminated cleanly */ } pa_stream_state_t; +/** Return non-zero if the passed state is one of the connected states */ +static inline int PA_STREAM_IS_GOOD(pa_stream_state_t x) { + return + x == PA_STREAM_CREATING || + x == PA_STREAM_READY; +} + /** The state of an operation */ typedef enum pa_operation_state { PA_OPERATION_RUNNING, /**< The operation is still running */ @@ -296,6 +312,7 @@ enum { PA_ERR_VERSION, /**< Incompatible protocol version */ PA_ERR_TOOLARGE, /**< Data too large */ PA_ERR_NOTSUPPORTED, /**< Operation not supported \since 0.9.5 */ + PA_ERR_UNKNOWN, /**< The error code was unknown to the client */ PA_ERR_MAX /**< Not really an error but the first invalid error code */ }; @@ -368,7 +385,15 @@ typedef struct pa_timing_info { pa_usec_t source_usec; /**< Time in usecs a sample takes from being recorded to being delivered to the application.
