[Cosmin Sabou [:CosminS]]

This looks to be perma on linux shippable builds and are two kinds of failures:

• https://treeherder.mozilla.org/logviewer?job_id=409856762&repo=mozilla-central
• https://treeherder.mozilla.org/logviewer?job_id=409852193&repo=mozilla-central

Will examine this issue in my day tomorrow.

[Jim Blandy :jimb]

Silencing the failure, but leaving the bug open to track the work - we do want to re-enable this test eventually.

Depends on D174125

Comment 13

[Erich Gubler [:ErichDonGubler]]

:CosminS: Those are not the same test cases failing as with the OP of this issue (webgpu:web_platform,canvas,context_creation:return_type:*), but they do appear to be missed in the same fashion as that case was. Apologies for missing those; submitted some patches above for review. 😅

I'll adjust the title of the bug to reflect the expanded scope of Linux shippable overall.

Comment 14

[Cosmin Sabou [:CosminS]]

Erich, thank you for the clarification and patches. Changing the summary that way will render this bug to be no longer suggested in Treeherder. Code sheriffs depend on that to accurately star the failures against this bug.

Comment 15

[Erich Gubler [:ErichDonGubler]]

Ah, okay. Thanks for your patience. I hadn't heard about that process before. ❤️

Comment 19

[Erich Gubler [:ErichDonGubler]]

Unassigning from myself, since it seems like the real work left to do is here solve the underlying bug (and we're not ready to take that on just yet).
