Comment 6

[Julian Descottes [:jdescottes]]

This seems to almost permafail since last week

Comment 7

[Mark Cornmesser [:markco]]

aerickson: Any thoughts?

Comment 8

[Julian Descottes [:jdescottes]]

For the record I plan to flag this as intermittent in https://bugzilla.mozilla.org/show_bug.cgi?id=1912239 so it won't show up in try builds anymore. I investigated a bit the failure and I think it's not a recent regression, the test has always been racy, but it's just much more frequent now.

Comment 9

[Andrew Erickson [:aerickson]]

Puppeteer != Puppet in this case. These failing jobs are running on running on gecko-t/t-linux-xlarge-source-gcp.

We haven't changed anything on these hosts recently as far as I know.

:jdescottes, do you know who owns Puppeteer tests?

Comment 10

[Julian Descottes [:jdescottes]]

I didn't notice that this was filed in the wrong component. This should be in Remote Protocol > Agent

Comment 11

[Henrik Skupin [:whimboo][⌚️UTC+2]]

I assume this is a regression from the Puppeteer 23.1.0 vendoring patch?

Comment 12

[Julian Descottes [:jdescottes]]

(In reply to Henrik Skupin [:whimboo][⌚️UTC+2] from comment #11)

I assume this is a regression from the Puppeteer 23.1.0 vendoring patch?

No this was permafailing before my patch, I noticed it when doing the vendoring (that's when I commented here).
So during the vendoring I skipped the test on CDP but we should investigate it.

Comment 14

[Henrik Skupin [:whimboo][⌚️UTC+2]]

The landing of the patch on bug 1906260 should have caused it. Marking it as a regression. As discussed with Julian this is not of high priority for us given that the same test works with BiDi and CDP is already marked as deprecated.

Comment 15

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

:mossop, since you are the author of the regressor, bug 1906260, could you take a look?

For more information, please visit BugBot documentation.

Comment 16

[Dave Townsend [:mossop]]

Given that this is a low priority I am not going to be working on this.

Comment 17

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

Set release status flags based on info from the regressing bug 1906260
