SUMMARY: ThreadSanitizer: data race /checkouts/gecko/dom/media/gtest/AudioVerifier.h:69:47 in PreSilenceSamples

I imagine this will be fixed by https://phabricator.services.mozilla.com/D209001.

Depends on: 1404972

I guess it's nice to see that we have tests which would have caught them if they were running in CI at the moment!

Another one to check back on after that lands:
https://treeherder.mozilla.org/logviewer?job_id=456471330&repo=try&lineNumber=34909
ThreadSanitizer: data race /builds/worker/checkouts/gecko/dom/media/gtest/AudioVerifier.h:74:5 in mozilla::AudioVerifier<float>::CheckSample(float)

FYI, you'll need to revert the below change to re-enable the test when there's a fix ready.
https://hg.mozilla.org/mozilla-central/diff/8ceeacec0dfd1398a7cc01d1b5a08ae5be835435/dom/media/gtest/moz.build

Try push on top of bug 1404972 is still showing some issues, albeit intermittently now.

SUMMARY: ThreadSanitizer: lock-order-inversion (potential deadlock) /checkouts/gecko/mozglue/misc/Mutex_posix.cpp:94:3 in mutexLock

Thanks for checking. I'll take a look.

This was hard to reproduce, but rr with --chaos helped: https://pernos.co/debug/f__HqLMFsmFoK2vFj3XJVQ/index.html

So this lock inversion is controlled and harmless, but happens when we exhibit the race explained here. The fix is easy. Same for the NotifyInputStopped call. I'll silence that warning too.
