Summary: Make TSan (ThreadSanitizer) usable with Firefox → [meta] Make TSan (ThreadSanitizer) usable with Firefox

Chiming into this bug, please direct me to a more appropriate bug if there exists one.

I've noticed that tsan is currently running on linux64 docker image. This has been phased out for the most part on mozilla-central, with tests now running with ubuntu1804-test docker image.

I have a push where I made the necessary changes to have tsan run with ubuntu1804-test docker image, and I have some failures:
https://treeherder.mozilla.org/#/jobs?repo=try&group_state=expanded&tier=1%2C2%2C3&revision=e41b65c04476a324e12f6699f2bb7b6b3fbed695

xpcshell

  • X2 chunk reports a bunch of TEST-UNEXPECTED-FAIL that I assume are legitimate failures (i.e not slow tests).

mochitest-plain

  • a persistent failure of toolkit/content/tests/widgets/test_videocontrols.html can be seen in chunk 4.
  • multiple failures are observed in chunk 5, retriggers are underway.

I'd like to have all of tsan migrated over to use ubuntu1804 before the list of test suites grows. Should I skip all of the failing tests with skip-if = tsan?
