Comment 11

[Tom Tung [:tt, :ttung]]

The main change in bug 1601594 is to when it's cross-origin-isolated, we use "origin" as the key of the DocGroup. I don't think we have tested that other than WPT tests for SharedArrayBuffer, COOP, and COEP. (in the failure log, they are reftests for layout, wpt test for webrtc).

The only thing might be related is that I only change the key of DocGroup from BaseDomain to SiteOrigin, but they shouldn't cause these test to hit the assertion for checking the number of documents in a DocGroup.

The elaborate more, my understanding for bug 1601594 is that it can cause a Document to get an incorrect DocGroup when unexpected/unhandled things happen (e.g. a pref is flip during runtime and that should be fixed in Bug 1641874) rather than DocGroup cannot find the Document.

Comment 12

[Andreea Pavel [:apavel]]

Retriggers show this is from a wpt sync: https://treeherder.mozilla.org/#/jobs?repo=autoland&searchStr=Windows%2C7%2Cdebug%2CWeb%2Cplatform%2Ctests%2Ctest-windows7-32%2Fdebug-web-platform-tests-e10s-4%2CW%28wpt4%29&fromchange=cb312ffd72236976ed05a0f252c6320bfc37ddca&tochange=6f0d4ca18e716221382c84112749ed634d333e41&selectedTaskRun=C2vPvjhFRnmj9-FreHx-4A.0

James could you take a look?

Comment 13

[James Graham [:jgraham]]

Looks like an intermittent crash in a WebRTC test. I am somewhat reminded of bug 1641974 so maybe bwc could look?

Comment 14

[Byron Campen [:bwc]]

Seems to be happening when we delete DataChannelConnections. Bug 1645219 is cleaning up that code quite a bit, maybe it will help?

Comment 15

[Byron Campen [:bwc]]

Let's see if we can reproduce the failure with the patch from bug 1645219.

Comment 16

[Byron Campen [:bwc]]

Not reproducing with rebuild=20. Retriggering some more.

Comment 17

[Byron Campen [:bwc]]

Yeah, this does not seem to reproduce with the patch from bug 1645219.
