[Henrik Skupin [:whimboo][⌚️UTC+1]]

Looks like this is some DOM code running as triggered by the cycle collector. If I'm wrong please move to another component.

Comment 2

[Andrew McCreight [:mccr8]]

This doesn't have anything to do with the cycle collector. We're running some Promise code, which is running JS, which looks like it is running CrashMonitor.sys.mjs and somehow in there we are calling abort. From the line number, maybe this is related to IOUtils.profileBeforeChange.addBlocker().

Comment 7

[Sarah Clements [:sclements]]

Mossop, would you have any idea about this? (someone suggested in triage this could be related to multi-profile work?)

Comment 8

[Dave Townsend [:mossop]]

profileBeforeChange is unrelated to profiles and just a way to do stuff on shutdown. We're probably crashing here in response to a blocker taking too long to execute. If it is actually CrashMonitor then that would be this which is odd because nothing in there looks like it would take very long.

Comment 9

[Nick Alexander :nalexander [he/him]]

I disagree with Dave: writing the session store file could be a long operation, especially in automation (but depending on many details).

There's a .dmp and .extra file, which should include the crash annotations, and those annotations should identify the outstanding shutdown blockers (or the active one). But I don't know how to extract crash annotations from those files.

:gsvelto: can you link to docs about inspecting those crash details from automation? Thanks!

I wonder if we even should be writing the session store on exit in automation. In the same way that we don't write Places data to disk in tests (https://bugzilla.mozilla.org/show_bug.cgi?id=1272025, but I see now that it adds options but doesn't enable them), maybe we don't want to crash in tests due to slow automation disks?

Comment 11

[Gabriele Svelto [:gsvelto]]

I'm afraid we don't really have some documentation about this (but we should). The .extra file is just JSON, holding a list of annotations and their contents. In particular I believe you would be looking at AsyncShutdownTimeout which should contain the information of the blocker Firefox got stuck into. The contents of AsyncShutdownTimeout are also JSON and in particular it should have two fields (name and conditions) which are described here. Automation typically calls mozcrash.check_for_crashes() which iterates over the crashes in the system, processes them and eventually move them to another directory for further processing (the crash reports are typically cleaned up at the end of each test). In particular when we're enumerating crashes, the info.extra field here should contain all the crash annotations of each crash.

Comment 12

[Gabriele Svelto [:gsvelto]]

Also FYI we plan on removing the CrashManager entirely in the near future, see bug 1911301.

In particular when we're enumerating crashes, the info.extra field here should contain all the crash annotations of each crash.

Looking at the .extra here, I see:

  "AsyncShutdownTimeout": "{\"phase\":\"IOUtils: waiting for profileBeforeChange IO to complete\",\"conditions\":[{\"name\":\"CrashMonitor: Writing notifications to file after receiving profile-before-change and awaiting all checkpoints written\",\"state\":{\"profile-after-change\":true,\"final-ui-startup\":true,\"quit-application-granted\":true,\"sessionstore-windows-restored\":true,\"quit-application\":true,\"profile-change-net-teardown\":true,\"profile-change-teardown\":true,\"profile-before-change\":true},\"filename\":\"resource://gre/modules/CrashMonitor.sys.mjs\",\"lineNumber\":165,\"stack\":[\"resource://gre/modules/CrashMonitor.sys.mjs:init:165\",\"resource://gre/modules/nsCrashMonitor.sys.mjs:observe:20\"]}]}",

Digging in, it's very clear that this is waiting for the session store final write to occur, via some observer notifications. Either that write is legitimately taking too long, or the observer notification is getting lost.

Looking at more of the crashes, they're all in the Marionette test TestWindowless.test_no_window_handles_after_silent_restart. It seems plausible that we're doing something unusual with session restore after these restarts, triggering this issue. Whether the issue is "real", or an artifact of the test harness, I cannot say.

:whimboo: you seem most knowledgable about the test in question. Are you aware of any possible interactions with the session restore mechanism that might cause the notification to get missed (or not sent, i.e., if no windows are opened?) that might be relevant? Can you investigate a little further based on the logs?

This test isn't doing anything with session restore but it might be a side-effect for MacOS only when restarting Firefox in silent mode? Maybe someone more familiar with session restore could comment on?

Is that failure also reproducible locally? A Gecko profile would be nice to have which could indicate some insights.

Alexander this could actually be related to bug 1758634 which actually depends on the "AsyncShutdown timeout in IOUtils: waiting for profileBeforeChange IO to complete" issue from the crash reporter (bug 1764420 ).
