Fri, 21 Oct 2011 17:14:19 -0700	Eric Wing	Workaround for terrible iOS 5.0 regression bug in Apple's OpenAL implementation with regards to resetting streaming sources. The fix uses a version check to determine if the workaround is employed. Once Apple fixes the problem, an upper bounds version check should be added.
Fri, 30 Sep 2011 17:48:23 -0700	Eric Wing	Fixed bug with seeking channels with predecoded samples. The OpenAL 1.1 spec specifies that a playing source should automatically jump when already playing. The code was unnecessarily recalling alPlaySource again which is not necessarily the correct thing to do. I think the previous code is another remnant of the Open 1.0 era. Also fixed bugs in the return codes for seek and rewind. For single channels, the return code was 0 channels processed in ALmixer which resulted in returning false to Lua. The implementation now should return 1/true for single channels, but 0/false for no channels. Errors will return -1/false.
Fri, 30 Sep 2011 16:44:08 -0700	Eric Wing	Workaround: There is a terrible OpenAL regression bug in iOS 5 dealing with streaming sources. alSourcei(source_id, AL_BUFFER, AL_NONE); fails to clear queued buffer queues on a streaming source. The workaround involves manually dequeuing the individual buffers before calling alSourcei(source_id, AL_BUFFER, AL_NONE);. But there is an additional race condition bug where the unqueue fails to take, so the included workaround keeps looping until the buffers finally report as cleared.
Thu, 29 Sep 2011 11:33:34 -0700	Eric Wing	Added addition query to get the current number of buffers processed in the new inner buffer decoupling loop because I've been seeing a lot of 59TestingError warnings. I think it is possible the value may become stale after the first iteration of the loop resulting in assumption failures which result in triggering this error.

Tue, 13 Sep 2011 18:03:21 -0700	Eric Wing	Split off background thread (threads only) termination and creation into separate functions from Interruption handling to make it easier to avoid race condition bug with Apple rdar://10081775 w.r.t. setting the OpenAL context. New APIs to suspend and resume update threads. Interruption handling calls these automatically.
