All/ParameterizedWebFrameTest.DISABLE_ON_TSAN(MaxFramesDetach) failing on linux_chromium_tsan_rel_ng

Project Member Reported by kbr@chromium.org, Nov 26 2017

Issue description

These two tests:
All/ParameterizedWebFrameTest.DISABLE_ON_TSAN(MaxFramesDetach)/0
All/ParameterizedWebFrameTest.DISABLE_ON_TSAN(MaxFramesDetach)/1

are failing on every build on linux_chromium_tsan_rel_ng that runs webkit_unit_tests. This is preventing CLs from landing which change build parameters, since these don't run retries.

It doesn't seem that either of the two most recent changes to this test were the cause:

https://chromium-review.googlesource.com/772430
https://chromium-review.googlesource.com/784930

and unfortunately it's been >200 builds since they were failing so it's not easy to see what regressed.

Everything also appears green on https://build.chromium.org/p/chromium.memory/console and https://ci.chromium.org/buildbot/chromium.memory/Linux%20TSan%20Tests/ .

CC'ing some folks who might have insight into what's going on.

Sheriffs, could you please track this down on Monday? Thanks.

+stgao as this would be a good candidate for FindIt and auto-revert.

The tests sounds disabled on TSAN enabled builds, why are they run on linux_chromium_tsan_rel_ng?

Re comment #1:

Many thanks kbr@ for sharing this case!
Unfortunately, these reliable failures only happended on CQ and Findit is not analyzing reliable failures on CQ.
I filed bug 789244 to collect more cases like this.
