This could be another weak map marking issue.

Flags: needinfo?(sphink)

Yeah, I wonder if this showing up now is a reaction to my last fix in bug 1651001.

It's interesting that the value is gray. I'll audit the code around that logic.

There is a new failure similar to this one:
https://treeherder.mozilla.org/logviewer.html#/jobs?job_id=313008242&repo=autoland&lineNumber=99614

Should the bug summary be modified to include it, or a new bug be made?

New bug, please. It's different, and surprising. Thank you!

It's been filed now as bug 1659151.

Still trying to reproduce this by combining gray marking and wrapper remapping, but no luck yet.

Gray marking had to be done carefully: just because an entry has been marked gray, it doesn't mean you can forget about it, because it might need to later be "upgraded" to black. (Oops; committed earlier than intended.) But that logic checks out.

I am starting to think that this may involve nuking and un-nuking (RemapDeadWrapper) a key. I'm attempting to write a test case, but it's tricky since it involves gray marking and controlling the exact order of things and even with enqueueMark, I would need to access objects in order to nuke or un-nuke them, and that would cause them to be marked black. I have a jsapi-test in development, which I have not yet managed to massage into showing this bug, but has possibly revealed a different subtle bug.

I believe this bug will only hit if incremental weakmap marking is enabled, and it is currently disabled. Marking various versions unaffected.

status-firefox83: --- → unaffected
status-firefox84: --- → unaffected

Should we unhide this bug?

Flags: needinfo?(sphink)

This bug requires incremental weakmap marking to be enabled, which it is not anywhere currently. But this should not be unhidden, even though it is not currently active; we would like to re-enable incremental at some point, and according to tcampbell the security people would like such bugs to keep their security categorization.

However, I have no near-term intention to re-enable incremental because of this bug and the lack of good benefits in pause times. (This is more about a performance cliff, and so it could become more pressing later as WeakMaps are used more.) In our meeting today, we decided that marking this as stalled is the correct disposition here. Note that this bug is not stalled in the sense that I usually use it, in that I have avenues for exploration that are still available. It's just that I don't have a reason to spend time on this.

Keywords: stalled

This will probably be fixed by bug 1711413.

Bug 1711413 is landed, and furthermore bug 1694538 and some followups have landed, any of which are likely to have resolved this issue. I'll mark this FIXED for now.
