Wim Taymans 94054fc1b7 gst/gstsystemclock.c: Fix anoying regression that survived a few releases. When adding an async entry while blocking ...
Original commit message from CVS:
* gst/gstsystemclock.c: (gst_system_clock_id_wait_jitter_unlocked),
(gst_system_clock_id_wait_jitter),
(gst_system_clock_id_wait_async), (gst_system_clock_id_unschedule):
Fix anoying regression that survived a few releases. When adding an
async entry while blocking on a sync entry, the sync entry will unblock
but still be busy, so it should continue to wait instead of returning
_BUSY to the app.
Add some comments here and there.
* tests/check/gst/gstsystemclock.c: (mixed_thread),
(mixed_async_cb), (GST_START_TEST), (gst_systemclock_suite):
Add testcase for this.
