* pthread_frame: save the FF_DEBUG_THREADS option in PerThreadContext.Wan-Teh Chang2017-07-11
| | | | | | | | | | | | | | | | | | | | | | Add the debug_threads boolean field to PerThreadContext. For PerThreadContext *p, p->debug_threads records whether the FF_DEBUG_THREADS bit is set in p->avctx->debug, and p->debug_threads and p->avctx->debug are kept in sync. The debug_threads field is defined as an atomic_int to allow atomic read by another thread in ff_thread_await_progress(). This fixes the tsan warning that 2e664b9c1e73c80aab91070c1eb7676f04bdd12d attempted to fix: WARNING: ThreadSanitizer: data race (pid=452658) Write of size 4 at 0x7b640003f4fc by main thread (mutexes: write M248499): #0 update_context_from_user [..]/libavcodec/pthread_frame.c:335:19 (5ab42bb1a6f4b068d7863dabe9b2bacc+0xe73859) [..] Previous read of size 4 at 0x7b640003f4fc by thread T130 (mutexes: write M248502, write M248500): #0 ff_thread_await_progress [..]/libavcodec/pthread_frame.c:591:26 (5ab42bb1a6f4b068d7863dabe9b2bacc+0xe749a1) Signed-off-by: Wan-Teh Chang <wtc@google.com> Signed-off-by: Ronald S.
