The blamed CL looks innocent.

Anyway, this hasn't failed since https://ci.chromium.org/buildbot/chromium.memory/Linux%20Chromium%20OS%20ASan%20LSan%20Tests%20%281%29/27073 , as far as I can tell, which is more than 30 hours ago now. Has someone fixed it?

FWIW, the test in question was added with https://codereview.chromium.org/1306053013

kelvinp seems to be inactive.

Now more than 50 hours since last failure, but I'm not sure if that proves anything, really.

I can't see the past failures, but the stack trace of the latest failure looks like specific to Mash/SingleProcessMash; receiving some Mojo events unexpectedly. Let's filter this for single-process-mash for now.

The following revision refers to this bug:
  https://chromium.googlesource.com/chromium/src.git/+/0a1ae4b7dd8ccd37b431be685a0c7d8f5583ba0e

Filter GetAuthTokenFunctionPublicSessionTest.NonWhitelisted for Mash

This test is flaky and seems Mash specific, see the bug for
the stack trace.

Jun, could you take a look at this?

Sorry didn't notice the bug was assigned. Fix looks pretty simple, failure is due to GetLoggedInUsers having no default, fix is to copy RestartDeviceTest's mock expectation.

Also here's a stack trace that's a little easier to make sense of


ninteresting mock function call - returning default value.
    Function call: GetLoggedInUsers()
    The mock function has no default action set, and its return type has no default value set.
