Taking a readlock after a writelock in the same thread should result in a deadlock, yet pthread on Linux returns EDEADLK and continues. glib-2.42.0 ignores EDEADLK and assumes the lock was taken. Releasing the lock later causes issues: "Calling g_rw_lock_writer_unlock() on a lock that is not held by the current thread leads to undefined behaviour." The issue at hand: AudioStreamView::redisplay_track() -> foreach_region() #<< WriteLock -> add_region_view() ... -> AudioRegionView::create_one_wave() -> RegionView::update_coverage_frames -> Playlist::top_unmuted_region_at() #<< ReadLock All current users of Playlist::foreach_region() are in the GUI and AFAICT read-only (display regions, update visuals) |
