In the last 7 days there have been 17 occurrences on linux1804-64, windows7-32 and windows10-64, build types debug and opt.

Recent failure: https://treeherder.mozilla.org/logviewer.html#/jobs?job_id=314381746&repo=mozilla-central&lineNumber=2221

Nathan, could you, please, direct this to someone who can take a look?

I think this is not necessarily a problem with MozPromise, but it looks like something in JS is not getting promises resolved at the proper time?

These failures look to all be in telemetry-tests-client-e10s, specifically in the test telemetry/marionette/tests/client/test_event_ping.py.

The Windows failures have crummy stacks, but the ASan ones seem to be reasonable. I'll try to take a further look tomorrow.

Well, I'm not really sure what is going on here. The crashes are happening very late in shut down when we're shutting down TaskController and there are a bunch of tasks remaining. Is that expected? Anyways, I guess one of those is some kind of promise runnable that was never resolved and so we assert.

It looks like the failure is happening when we're on line 51 of the .py test, which is:
payload = self.wait_for_ping(self.restart_browser, EVENT_PING)["payload"]

Presumably the restart_browser is causing the browser to shut down, which is causing the other issues. There are a lot of JS promises in this test, so maybe those are related to the MozPromise. Anyways, I've reached my limit of understanding here.

The good news is that it looks like there was just a big spike earlier in the week, and it hasn't happened as much since then, so maybe there's no issue here? I still don't entirely understand what the assertion is supposed to be.

This appears to have been made worse by bug 1793496, which added the promise failing in the log in comment 104. In this specific case, what is happening is that:

a TaskQueue is created over the main thread, which will be used as the target for the MozPromise (https://searchfox.org/mozilla-central/rev/88f285c5163f73abd209d4f73cfa476660351982/dom/media/systemservices/video_engine/tab_capturer.cc#50-52).
CaptureFrame is called, which dispatches async tasks to run on this task queue [^note] (https://searchfox.org/mozilla-central/rev/88f285c5163f73abd209d4f73cfa476660351982/dom/media/systemservices/video_engine/tab_capturer.cc#89-115)

FWIW the [&] captures in the CaptureFrame method are very buggy, and only happen to not cause stack UAFs because the only captured variable is this. You should never use [&] captures for async operations, as they capture references into the stack frame.

The TabCapturerWebrtc is destroyed, which tries to block until the TaskQueue is destroyed (https://searchfox.org/mozilla-central/rev/88f285c5163f73abd209d4f73cfa476660351982/dom/media/systemservices/video_engine/tab_capturer.cc#55-58). This likely completes and returns fairly quickly, as there are no tasks in the queue.
At some point the DOM promise which was being waited on is resolved, and it tries to resolve (or reject) the promise from a microtask: https://searchfox.org/mozilla-central/rev/88f285c5163f73abd209d4f73cfa476660351982/dom/media/systemservices/video_engine/tab_capturer.cc#153
This tries to dispatch an event to the mMainThreadWorker event target, which has been shut down. Because it's been shut down, the dispatch fails. TaskQueues don't leak the events dispatched to them on shutdown (though that would lead to a different error, due to leaked objects), so the runnable is instead destroyed, and we hit this assertion because the resolve runnable was destroyed without the promise ever being resolved.

The mechanism of using a custom TaskQueue to try to ensure the capture completes before the TabCapturerWebrtc is destroyed doesn't look like it works, and it instead causes this other issue. A different mechanism will need to be used.

In addition, the [&] captures should be removed from CaptureFrame(), and there should be more detailed comments justifying why this stays alive long enough.

I've come to much of the same conclusion and am fixing this in bug 1795542. Sorry you had to spend all that time investigating and thanks for the thorough analysis!
