Comment 1

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

Hi Tom, another sharedarraybuffer failure on beta. Shall the test's expectation be updated?

Comment 2

[Tom Tung [:tt, :ttung]]

I cannot find the file "/workers/postMessage_block.https.html" in wpt tests through searchfox. Do I miss something?

Edited: I meant that it implies the test just landed

Comment 3

[Tom Tung [:tt, :ttung]]

I would assume that test needs to set up the COOP+COEP headers, but I would be rather surprised that it didn't fail on m-c when it's landed?

Comment 4

(In reply to Tom Tung [:tt, :ttung] from comment #3)

I would assume that test needs to set up the COOP+COEP headers, but I would be rather surprised that it didn't fail on m-c when it's landed?

It looks like it's with COOP and COEP because there is testing/web-platform/tests/workers/postMessage_block.https.html.headers in https://hg.mozilla.org/mozilla-central/rev/69db48f9993a

Comment 6

[Tom Tung [:tt, :ttung]]

I wonder if it's beacuse we need to enable some prefs. I will test and provide a patch.

Comment 7

[Tom Tung [:tt, :ttung]]

Attachment: Bug 1635420 - Enable the prefs for COOP, COEP, postMessage, SharedArrayBuffer to the wpt test;
