Comment 3

[Andrew McCreight [:mccr8]]

These leaks are happening during WebGPU WPTs. The BrowserFoo stuff is showing up just because it is first alphabetically: there are various other things leaking.

Comment 4

[Noemi Erli[:noemi_erli]]

This starts to permafail, retriggers and backfills are revealing this:
https://treeherder.mozilla.org/#/jobs?repo=autoland&resultStatus=pending%2Crunning%2Csuccess%2Ctestfailed%2Cbusted%2Cexception&searchStr=a180f3247b4f9cf520cb0eb0897d2f96e451c80c&tochange=b45f47bb9911f54c3ffce69ed90d5f6a65dae61d&fromchange=3d9a64be67bc645e0b69667bee0f23a589448812

Could this be regressed by https://bugzilla.mozilla.org/show_bug.cgi?id=1592297?

Comment 5

[Tom Ritter [:tjr]]

It's possible, but I don't think so. leakcheck is a separate file from leaks.py (which 1592297 modified.) 1592297 is primarily just changing logging around, and none of the leaked objects in the log are any of the classes I modified.

[Andreea Pavel [:apavel]]

Joel any insight on how to deal with this? it's not perma-failing, but failure rate is high.

(In reply to Andrew McCreight [:mccr8] from comment #3)

These leaks are happening during WebGPU WPTs. The BrowserFoo stuff is showing up just because it is first alphabetically: there are various other things leaking.

Just to clarify, there is no WebGPU logic going on, right? Because the "dom.webgpu.enabled" is false by default, we shouldn't be creating any WebGPU objects.

right after the error we do the leak checking, I would like to see this error fixed to see if this leak goes away. I am not sure it will go away as this is osx/debug specifically.

As a note this falls into the criteria to disable a test given the high frequency.

Comment 10

[Dzmitry Malyshau [:kvark]]

We don't have createRenderPipeline implemented yet, it's not a matter of "fixing" as much as progressing towards a prototype implementation. I suggest we disable the whole webgpu WPT category now, and I'll be enabling it gradually as more WebGPU implementation bits land.

That is to say, I'm still confused as to why the error didn't happen earlier (i.e. at the initialization): all WebIDL interfaces are behind the pref: https://searchfox.org/mozilla-central/rev/efdf9bb55789ea782ae3a431bda6be74a87b041e/dom/webidl/WebGPU.webidl#59

Ah, if this is all preffed off, then maybe it is some kind of generic DOM leak issue.
