2012-11-17build-sys: Drop ChangeLog generationArun Raghavan1-5/+0
This drops ChangeLog generation from git. It does not make sense to distribute 500 kB of ChangeLog given how easy it is these days to browse history with git. We might replace this with a release-annoucement-esque high-level summary of changes.

2012-11-16build-sys: Bump BlueZ dependency to 4.99Arun Raghavan1-1/+1
Since the old UNIX fd IPC mechanism was removed and we rely on the D-Bus based API, this is the oldest version that is known to reliably work.
2012-11-16modules: Micro-optimisation for rewind_requested pathsArun Raghavan12-12/+12
Since some devices can be chatty with regards to how often they return from poll(), this adds a PA_UNLIKELY() to all the the rewind_requested checks in our sink modules to make the general case (no rewind was requested) the fast path.
2012-11-16sink: Process rewind requests also when suspended.Tanu Kaskinen14-60/+57
When a rewind is requested on a sink input, the request parameters are stored in the pa_sink_input struct. The parameters are reset during rewind processing, and if the sink decides to ignore the rewind request due to being suspended, stale parameters are left in pa_sink_input. It's particularly problematic if the rewrite_bytes parameter is left at -1, because that will prevent all future rewind processing on that sink input. So, in order to avoid stale parameters, every rewind request needs to be processed, even if the sink is suspended. Reported-by: Uoti Urpala
2012-11-16sink, source: Prevent unnecessary rate update attemptsArun Raghavan4-18/+10
We don't need to try a rate update if the desired sample rate is the same as the one the sink or source is already using.

2012-11-15mainloop: Don't care about the mainloop state variable when waking up the ↵Tanu Kaskinen1-1/+1
mainloop. If the mainloop is just about to enter polling, but m->state is not POLLING yet when some other thread calls pa_mainloop_wakeup(), the mainloop will not be woken up. It's safe to write to the wakeup pipe at any time, so let's just remove the check.

2012-11-08pulse: Fix hole handling in pa_stream_peek().Tanu Kaskinen2-9/+31
Previously, if there was a hole in a recording stream, pa_stream_peek() would crash. Holes could be handled silently inside pa_stream_peek() by generating silence (wouldn't work for compressed streams, though) or by skipping any holes. However, I think it's better to let the caller decide how the holes should be handled, so in case of holes, pa_stream_peek() will return NULL data pointer and the length of the hole in the nbytes argument. This change is technically an interface break, because previously the documentation didn't mention the possibility of holes that need special handling. However, since holes caused crashing anyway in the past, it's not a regression if applications keep misbehaving due to not handing holes properly. Some words about when holes can appear in recording streams: I think it would be reasonable behavior if overruns due to the application reading data too slowly would cause holes. Currently that's not the case - overruns will just cause audio to be skipped. But the point is that this might change some day. I'm not sure how holes can occur with the current code, but as the linked bug shows, they can happen. It's most likely due to recording from a monitor source where the thing being monitored has holes in its playback stream. BugLink: http://bugs.launchpad.net/bugs/1058200

This reverts commit 1569601864af375c3788fbce429b6773bd48072e. Rethinking this, it makes more sense to not add this to the check framework. This is mostly useful for exposing ALSA driver issues, and it's handy to be able to build this as a standalone executable.

2012-11-03Revert "core: adjust playing_for and underrun_for at rewind"Arun Raghavan1-22/+4
This reverts commit 5bc6cadcb2e7255fd333ed88cc80b61a7673ddd9. I wasn't meaning to push this out - just merged for review / testing.
2012-10-31core: adjust playing_for and underrun_for at rewindUoti Urpala1-4/+22
A rewind may erase data that sink_input counted in playing_for or underrun_for earlier. Add code adjusting those values after a rewind. One visible symptom of this bug was problems recovering from an underrun. When a client calls pa_stream_write() with a large block of memory, the function can split that into smaller pieces before sending it to the server. When receiving new data for a stream that had silence queued due to underrun, the server would do a rewind to replace the queued-but-not-played silence with the new data. Because of the bug, this rewind itself would not change underrun_for. It's possible for multiple rewinds to be done without filling the sink buffer in between (which is what would eventually reset underrun_for). In this case, the server rapidly processing the split packets would rewind the stream for _each_ of them (as underrun_for would stay set), erasing valid audio as a result.
2012-10-30svolume: Fix ARM alignment issuesArun Raghavan1-41/+60
As Peter Meerwald <p.meerwald@bct-electronic.com> discovered, our ARM svolume code performance is quite terrible when the incoming samples are not word-aligned. This can very easily be the case, since the architecture only requires that the samples be 16-bit aligned, and we might end up running the innermost loop after processing modulo-4 samples. The performance degradation was ~50x on a Cortex A9 (Pandaboard). This reworks the svolume logic to first consume enough samples to make sure the rest is word aligned, and reordering the processing to work with 4 samples at a time first, and then finally deal with the remainder. With this, performance is comparable for arbitrary alignments (~3x faster than the C code).

2012-10-30match: Use the SINK_INPUT_FIXATE hook instead of NEW.Tanu Kaskinen1-5/+5
The callback relies on the sample spec being finalized, which is not true with the NEW hook. In case you're wondering about the "hook EARLY - 1, to match before stream-restore" comment that was not changed even though the code that the comment concerned was changed: the comment was apparently written at a time when module-stream-restore used the NEW hook too, and later stream-restore has been changed to use the FIXATE hook. So, the comment was wrong/nonsensical before this patch. Since these two modules now use the same hook again, the comment makes sense again. BugLink: https://bugs.freedesktop.org/show_bug.cgi?id=55135
2012-10-30combine: Keep the timer active in the null mode only when running.Tanu Kaskinen1-5/+3
Previously thread_func() used PA_SINK_IS_OPENED() to check whether some data should be rendered. process_render_null() used a different check: it would return immediately if the sink was not in the RUNNING state. This caused a busy loop when the sink was in the IDLE state, because process_render_null() didn't update the timestamp, and thread_func() still kept the timer active using the old timestamp. pa_rtpoll_run() would return immediately because of the old timestamp. This is fixed by using the same check in both thread_func() and process_render_null(). Since the checks are the same, it's actually redundant to have the check in process_render_null(), so it is now an assertion. BugLink: https://bugs.freedesktop.org/show_bug.cgi?id=54779
2012-10-30virtual-surround-sink: Fix setting max_request and max_rewind.Tanu Kaskinen1-2/+2
The sink has different frame size than the sink input, so the max_request and max_rewind values of the sink input need to be converted when setting the sink max_request and max_rewind values. The conversion is already done correctly in sink_input_update_max_request_cb() and sink_input_update_max_rewind_cb().
2012-10-30loopback: Don't fix the source output format/rate/channels.Tanu Kaskinen1-9/+0
Once the sink input has been routed in pa_sink_input_new(), the sample spec and channel map have already become fixed. The sink input and source output must use the same stream format, because the data is copied as-is.
2012-10-30loopback: Use the real sample spec once it's known.Tanu Kaskinen1-0/+5
When module-loopback is loaded without arguments, the ss and map variables are initialized with dummy values. This caused a problem, because also pa_memblockq_new() was called with the dummy values, making it work incorrectly. The base was set to 1 instead of the real frame size, which in turn caused alignment related crashes.
2012-10-30resampler: Make sure that there are no overflows when multiplying ↵Tanu Kaskinen1-6/+6
potentially big numbers. This fixes at least one crash that has been observed. The multiplication in trivial_resample() overflowed when resampling from 96 kHz to 48 kHz, causing an assertion error: Assertion 'o_index * fz < pa_memblock_get_length(output->memblock)' failed at pulsecore/resampler.c:1521, function trivial_resample(). Aborting. Without the assertion, the memcpy() after the assertion would have overwritten some random heap memory.
2012-10-30memblockq: Fix the order of setting minreq and prebuf.Tanu Kaskinen2-3/+3
2012-10-30core-util: Don't error out on existing runtime directory.Thomas Martitz1-2/+3
When compiling without HAVE_SYMLINK the runtime dir is a real directory, which is attempted to be created. In the case it already exists we shouldn't error out. The HAVE_SYMLINK-enabled code already does this.
2012-10-30core: Proper poll() emulation to fix pacat and friends on WindowsThomas Martitz4-19/+645
Currently, Windows versions of pacat and friends fail because the current poll emulation is not sufficient (it only works for socket fds). Luckily Gnulib has a much better emulation that seems to work good enough. The implementation has been largely copied (except a few bug fix regarding timeout handling, to be pushed upstream) and works on pipes and files as well. The copy has been obtained through their gnulib-tool utility, which gives a LGPLv2.1+ licensed file. This fixes the "Assertion (!e->dead) failed" error coming and lets pacat and friends stream happily to/from a server (I didn't actually test parec).
2012-10-30build-sys: Drop -Wvla from compiler flagsArun Raghavan1-1/+1
Since we mandate C99 support, not reason to keep this around.
2012-10-30tests: Fix a cpu-test debug messageArun Raghavan1-3/+3
We align at sample granularity and not byte granularity (which might violate arch alignment requirements).
2012-10-30tests: Run svolume on different channel countsArun Raghavan1-46/+43
This adds checks to run svolume tests with 1, 2 and 3 channels (we don't run Orc with 3 channels since only 1/2-ch are implemented there).
2012-10-30tests: Make cpu-test less verboseArun Raghavan1-7/+4
Drops the correctness debug output since we want to run this several times, and the output becomes much more verbose than required.
2012-10-30tests: Run svolume test for various sample alignmentsArun Raghavan1-29/+77
Allows us to make sure that svolume works independently of sample alignment, and that performance doesn't degrade based on this.
