Comment 1

[Jonathan Kew [:jfkthame]]

Ugh... if we're in shutdown, we really don't care about dispatching this; we should just bail out. I'll see if I can find a tidy way to do that. Leaving needinfo flag until I look into it more thoroughly.

(Aside from the assertion creating test-failure noise, this is basically harmless.)

[Jonathan Kew [:jfkthame]]

I think the simplest thing to do here is to check in GetPrefsAndStartLoader whether we've entered AppShutdown already, and if so, just bail out -- there's no point in initializing more font information when the app is shutting down anyway.

In theory there'll still be a potential race between checking the AppShutdown state and trying to dispatch the runnable, but the risk of getting all the way from "we're not shutting down" to "the thread manager is done" here seems negligible. And if it were ever to happen, it's basically harmless; the only issue here is the noise we get in CI from the debug-mode assertion that we trigger.

Hi Jonathan, can we take this on ESR to quiet the failures there too?

Comment 28

[Jonathan Kew [:jfkthame]]

Sure thing - I don't think there's any significant risk to the patch.

Bug 1771125 - Don't bother trying to start the font-info loader if we're already shutting down. r=lsalzman

ESR Uplift Approval Request

• If this is not a sec:{high,crit} bug, please state case for ESR consideration: Annoying intermittent shutdown crashes
• User impact if declined:
• Fix Landed on Version: 106
• Risk to taking this patch: Low
• Why is the change risky/not risky? (and alternatives if risky): Trivial patch to just bail out of starting new work if we're in shutdown
