Andrew Kelley 66c7d1b1ac add symbol versioning 
closes #40

Andrew Kelley f61acfd953 ALSA: fix potential cleanup deadlock 
The main ALSA poll now includes another file descriptor which we
write to when cleaning up, to ensure that the poll terminates
when soundio_outstream_destroy is invoked.

closes #36

Andrew Kelley d168a7d192 ALSA: better device detection 
* Don't suppress sysdefault.
 * If default and sysdefault are missing, use the first device as
   the default device.
 * In sio_record example, don't segfault when device not found or
   probe error.
 * Workaround for Raspberry Pi driver that incorrectly reports
   itself as Output when it is actually Input.

See #44.

Andrew Kelley ee7c0d3e11 convert source code to pure C 
List<T> is now a really ugly macro.

Added a workaround for jack.h not putting `void` in function
prototypes for functions that take no arguments. I made upstream
pull requests to jack1 and jack2 but I don't have high hopes
about them getting merged.

I removed the lock-free atomic asserts. clang reports
non-lock-free atomics when in fact it does have lock-free
atomics. I inspected the generated code for gcc and clang
for fetch_add, load, and store, on x86_64 and armhf, and
it's all lock free.

Closes #45.

Andrew Kelley 8e30053962 JACK: delete broken pause implementation 
Previously, calling soundio_outstream_pause or soundio_instream_pause
during the write_callback or read_callback would cause a deadlock. Now,
attempting to pause always results in SoundIoErrorBackendIncompatible.

Closes #39

Andrew Kelley 2f14aa569e ALSA: use period size to calculate buffer size 
determining the buffer size before the period size sometimes results
in EINVAL.

closes #33

Andrew Kelley db0e3d136c fix double clean up corruption when opening stream fails 
affects ALSA, CoreAudio, JACK, WASAPI, and Dummy.

Andrew Kelley 277bb3106b dummy: fix deadlock when pause called from write_callback 2015-10-06 19:36:57 -07:00
Andrew Kelley a3c4f85489 ALSA: fix deadlock under some circumstances 
If the write_callback came upon an error during the prepare
phase, and never wrote any frames to the hardware buffer,
and another thread tried to soundio_outstream_destroy, this
would cause a deadlock.

This is now fixed.

Andrew Kelley 918183adc6 ALSA: be ready for /dev/snd to not be available 
If this occurs, the system has no ALSA support in the kernel,
and it is appropriate for the backend to fail.
