Could this be caused by the changes from https://bugzilla.mozilla.org/show_bug.cgi?id=1613985?
https://hg.mozilla.org/mozilla-central/rev/2f805278e33e

Comment 2

[Simon Giesecke [:sg] [he/him]]

I don't think so, but I will check. How can I create a "central-as-beta" build locally to verify that?

You can find more steps on how to do that here: https://wiki.mozilla.org/Sheriffing/How_To/Beta_simulations#TRUNK_AS_EARLY_BETA

Comment 4

[Simon Giesecke [:sg] [he/him]]

Unfortunately, there's no information on how to do a local build there.

Comment 5

[Noemi Erli[:noemi_erli]]

Sebastian, can you please share your thoughts here?

Comment 6

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

This is a regression from bug 1603484 (treeherder hides the central-as-beta revision because it had already been pushed): https://treeherder.mozilla.org/#/jobs?repo=try&revision=ac368f1b82331d8b715e8de83db90d24d5b1b48d&selectedJob=288756173

Regarding the question how to do local central-as-beta builds: If a debug or normal opt build are sufficient, run the command mentioned at https://wiki.mozilla.org/Sheriffing/How_To/Beta_simulations#TRUNK_AS_EARLY_BETA with the also mentioned --no-push, hg commit and run the build

Comment 7

[Perry Jiang [:perry] [no longer employee, use ni?]]

Tom, I think this is related to SAB interfaces being exposed or not, can you take a look?

Comment 8

[Tom Tung [:tt, :ttung]]

The error message looks like cannot sharedwork construct arrayBufferOrSharedArrayBuffer anymore?
I did an AB test and D62371 affects the result. Will look into it more.

I guess SharedWorker throws when constructing an SharedArrayBuffer so that the wpt test timeout'ed when SAB is disabled (it's only enabled on early Beta and Nightly). D62371 only reveals this issue.

Now the problem is why it SharedWorker behaves differently from other workers.

Wait, I added try {} catch () {} block at [1] and it actually throws when it run in all kinds of workers and windows (when I ran all tests with a late Beta build).

Ah, I think I figure the reason why. All other subtests (serviceworker, dedicated worker, windows) are expected "Error".

There a few test failures, but I couldn't find any failure related to /encoding/streams/decode-utf8.any.sharedworker.html.

ni back in case you referred to something else.

(Since the patch only change decode-utf8.any.ini, I'm going to land the patch)

No, wasn't referring to anything in particular, just the number of failures seemed a lot. Thanks for checking.
