This is actually a regression from the wpt downstream sync from January 10th on bug 1938103. Freddy can you please take a look?

Comment 2

[BugBot [:suhaib / :marco/ :calixte]]

Set release status flags based on info from the regressing bug 1938103

Comment 3

[Frederik Braun [:freddy]]

That one looks simple. taking a look.

Comment 4

[Frederik Braun [:freddy]]

Ah, no. I thought there were new instances but this is a duplicate of https://github.com/web-platform-tests/wpt/pull/49867, which just needs merging.

Comment 5

[Henrik Skupin [:whimboo][⌚️UTC+2]]

This is still affecting our CI so we should keep it open until the mentioned PR has been fixed. That way we can track and classify test failures correctly. The downstream sync of this fix will happen via bug 1939700.

Comment 6

[Frederik Braun [:freddy]]

Why are there so many bugs for just one upstream change?

I am now counting four.

• https://bugzilla.mozilla.org/show_bug.cgi?id=1938103
• https://bugzilla.mozilla.org/show_bug.cgi?id=1938984
• https://bugzilla.mozilla.org/show_bug.cgi?id=1939700
• this one right here.

Comment 7

[Henrik Skupin [:whimboo][⌚️UTC+2]]

Bug 1938103 is the original wpt sync bug when the test changes were initially downstream synced. Then bug 1938984 was created by the wpt sync bot to inform the triage owner of a component of new failures. This bug should have as best been updated to reflect the actual failure that can be seen in CI. With your upstream fix on the wpt repository directly the crash will go away once bug 1939700 is landed by the sync bot.

Best here is when you just duplicate bug 1938984 against this one and all will be fine?

Comment 12

[Henrik Skupin [:whimboo][⌚️UTC+2]]

Freddy, to make it easier it might be good to just provide a patch here on this bug, push it to try to verify that it works and get it landed. Then the wpt sync bot will run an upstream sync. That would as well be faster to get this failure fixed in our CI.

Comment 13

[Frederik Braun [:freddy]]

I just built from latest central a couple of minutes and ran the test locally, I saw no failures at all. I don't get it :|

Oh, nevermind I get it 🤦
