221688 2021-02-10 10:18:21 -0800 [GPUP] Two tests related to media element state are flaky when media in GPU Process is enabled 2021-03-03 15:54:56 -0800 1 1 1 Unclassified WebKit Media Other Unspecified Unspecified RESOLVED FIXED https://bugs.webkit.org/show_bug.cgi?id=123010 InRadar P2 Normal --- 221830 1 peng.liu6 peng.liu6 eric.carlson ews-watchlist glenn jer.noble philipj sergio webkit-bug-importer oldest_to_newest 1727601 0 peng.liu6 2021-02-10 10:18:21 -0800 media/W3C/video/networkState/networkState_during_loadstart.html media/W3C/video/readyState/readyState_during_loadedmetadata.html 1730353 1 webkit-bug-importer 2021-02-17 10:19:14 -0800 <rdar://problem/74439045> 1735046 2 peng.liu6 2021-03-02 14:54:09 -0800 Test media/W3C/video/readyState/readyState_during_loadedmetadata.html is passing consistently on bots now. Test media/W3C/video/networkState/networkState_during_loadstart.html still fails. But in order to reproduce the failure locally, I have to run more than 2 iterations. Like below: run-webkit-tests --no-build media/W3C/video/networkState/networkState_during_loadstart.html --no-retry-failures --iterations=3 1735053 3 peng.liu6 2021-03-02 15:02:27 -0800 Looks like when we run MediaPlayerPrivateAVFoundationObjC in the GPU process, MediaPlayerPrivateAVFoundation::m_networkState changes from MediaPlayer::NetworkState::Loading to MediaPlayer::NetworkState::Loaded quickly, and HTMLMediaElement is notified (HTMLMediaElement::setNetworkState() is called) before the "loadstart" event handler haves the chance to execute. HTMLMediaElement::setNetworkState() will set m_networkState to NETWORK_IDLE in the process, but the test expects expects m_networkState to be NETWORK_LOADING in the "loadstart" event handler. 1735056 4 peng.liu6 2021-03-02 15:07:14 -0800 I don't think the flaky failure will impact the functionality. 1735145 5 422028 peng.liu6 2021-03-02 17:41:58 -0800 Created attachment 422028 Patch 1735573 6 ews-feeder 2021-03-03 15:54:55 -0800 Committed r273853: <https://commits.webkit.org/r273853> All reviewed patches have been landed.
