Comment 2

[Ryan VanderMeulen [:RyanVM]]

Hrm, for fun I did a Try push of bug 1747349 uplifted to ESR91 to see if it made the leaks reported in bug 1701016 disappear, but now this one is getting reported with high frequency instead. But this didn't hit trunk until a week after bug 1747349 landed?

EDIT: Nevermind, this bug was already hitting ESR before too. I guess it just wasn't being classified previously since it was below the leaks from bug 1701016 in the logs.

[Ryan VanderMeulen [:RyanVM]]

Going back through the ESR logs, I believe I actually found when it started there. Appears to be from bug 1729642.

Comment 14

[Jonathan Kew [:jfkthame]]

We appear to be leaking an nsDynamicAtom that was created by the nsLanguageAtomService here. I'm having trouble figuring out how that can happen, unless something causes us to re-initialize gfxPlatform (and hence the font-list and language-atom service etc that it references) during shutdown, after we think we've done cleanup.

One thing we can perhaps try here is to ensure GfxInfo checks whether gfxPlatform is uninitialized (or has been torn down already) and bails out instead of potentially re-initializing it late in shutdown, which may be what's happening here. I notice that some GfxInfoBase methods include a check for gfxPlatform::Initialized() before they attempt to use it, but it's missing from the GetContentBackend method.

Looks the failures only hit Linux and macOS, but regardless, we were still hitting these leaks on builds after the patch landed anyway :(

I can't find anything in the failed test that remotely relates to the code that was in bug 1753758, i.e., none of the utility process related tests are ran in this, and the stack only refers to gfx?

https://treeherder.mozilla.org/logviewer?job_id=366988740&repo=autoland&lineNumber=73596

Yeah - the stack changed, as gfxPlatform is no longer getting initialized by GfxInfo, but it ends up getting inited anyway when we create a window (nsAppStartup::CreateChromeWindow etc in the stack) and the same atom leak shows up. So the patch here (that was backed out) probably doesn't help at all.

The second leak that appears in the same log appears to be related to localization (L10nReadyHandler::ResolvedCallback etc on the stack), but again what's being leaked is an nsDynamicAtom. I can't see where we're explicitly leaking a reference to these atoms; the alternative possibility is that they're getting created after we think we've cleaned up the atom table, so they're missed by the cleanup. But I also don't see quite how that would be happening...

(In reply to Sebastian Hengst [:aryx] (needinfo me if it's about an intermittent or backout) from comment #22)

More frequent from bug 1587094.

That doesn't make sense to me; bug 1587094 didn't change anything on Linux (the changes there were in Windows-specific platform code). A few cross-platform files were touched but only to rename a couple fields/methods; there no functional change to them.

Comment 28

[Jonathan Kew [:jfkthame]]

No, since the attempt in https://phabricator.services.mozilla.com/D138040 didn't help (comment 18), I don't have any clear idea how to resolve this.

Maybe we should just add a valgrind suppression entry for it, given that failing to clean up a dynamic atom isn't actually going to hurt users in any way that I can see.

Comment 37

[Jonathan Kew [:jfkthame]]

No, I'm currently busy with some higher-priority stuff, so unassigning myself from this bug for now, at least.

As noted in comment 28, my inclination here would be to just add a suppression entry. But Lee might have a better idea?

Comment 38

[Lee Salzman [:lsalzman]]

I am okay with the idea of a suppression entry. I looked a little bit and don't see an obvious explanation either.

Comment 40

[Sebastian Hengst [:aryx] (needinfo me if it's about an intermittent or backout)]

Andrew, could you add a suppression rule for this issue?

Comment 41

[Andrew McCreight [:mccr8]]

I don't know anything about valgrind's leak checking. I'll try to find some time to look into it.

Comment 42

[Jonathan Kew [:jfkthame]]

I believe it's just a case of adding an entry to build/valgrind/x86_64-pc-linux-gnu.sup. I'll put up a patch.
