Comment 8

[Brian Hackett [Laid off!]]

(In reply to Cristina Coroiu [:ccoroiu] from comment #4)

There are 31 failures in the last 7 days.

Brian, could be from https://bugzilla.mozilla.org/show_bug.cgi?id=1533202?
https://treeherder.mozilla.org/#/jobs?repo=mozilla-inbound&revision=0ad12e8fb98c2c20a249cdd9bed5e032a71c500f&selectedJob=241168949

Yeah, this could be from bug 1533202. Except for a pretty minor change to dom/workers/RegisterBindings.cpp, that bug didn't touch C++ at all, and the new JS logic and test aren't doing anything particularly strange. The new test may have exposed an existing bug in the interface between the DOM and worker runtimes or in the JS engine, though. I believe this assertion failure means that the worker runtime is being destroyed while there are still references to some of its contents.

Current failures seem to happen in debugger-related tests => changing component :)

I can look at this, but I can't reproduce this locally so it will probably take some time to track down. The test should be disabled in the interim I think.

[Jason Laster [:jlast]]

Brian, have you had a chance to look into the dbg-worker-scopes intermittent?

Comment 26

[Brian Hackett [Laid off!]]

I've tried to reproduce this, but can't do so locally. Debugging a leak like this on try would be extremely difficult I think, though having an rr recording should make it much easier to track down. I don't consider this a high priority because I don't think it's a devtools bug, though. It seems more likely to be an existing JS/Gecko issue that was exposed by this test, and since the test is still running on most platforms it still provides coverage.

Makes sense.
