Are some headers missing? 1791887 2 cdumez 2021-09-09 07:26:15 -0700 (In reply to Yusuke Suzuki from comment #1) > @Chris > I opened > https://w3c-test.org/html/infrastructure/safe-passing-of-structured-data/ > shared-array-buffers/serialization-via-history.https.html and it said there > is no SharedArrayBuffer. > Are some headers missing? I see: assert_throws_dom: function "() => { history[method](new SharedArrayBuffer(), "dummy title"); }" did not throw The subtests are failing for me but not due to lack of SharedArrayBuffer support. From Web Inspector, I can see that the test is serving the COOP+COEP headers: Cross-Origin-Embedder-Policy: require-corp Cross-Origin-Opener-Policy: same-origin @Yusuke, I've enabled COOP + COEP by default only very recently. Maybe you tested on a build that didn't have them enabled yet? 1792168 3 ysuzuki 2021-09-09 16:59:18 -0700 (In reply to Chris Dumez from comment #2) > (In reply to Yusuke Suzuki from comment #1) > > @Chris > > I opened > > https://w3c-test.org/html/infrastructure/safe-passing-of-structured-data/ > > shared-array-buffers/serialization-via-history.https.html and it said there > > is no SharedArrayBuffer. > > Are some headers missing? > > I see: > assert_throws_dom: function "() => { history[method](new > SharedArrayBuffer(), "dummy title"); }" did not throw > > The subtests are failing for me but not due to lack of SharedArrayBuffer > support. > > From Web Inspector, I can see that the test is serving the COOP+COEP headers: > Cross-Origin-Embedder-Policy: require-corp > Cross-Origin-Opener-Policy: same-origin > > @Yusuke, I've enabled COOP + COEP by default only very recently.

Hmm, I've tried opening https://w3c-test.org/html/infrastructure/safe-passing-of-structured-data/shared-array-buffers/serialization-via-history.https.html with WebKit r282238, but I'm getting an error assert_throws_dom: function "() => { history[method](new SharedArrayBuffer(), "dummy title"); }" threw object "ReferenceError: Can't find variable: SharedArrayBuffer" that is not a DOMException DataCloneError: property "code" is equal to undefined, expected 25 I also opened the inspector, and it seems that SharedArrayBuffer is not defined. Is some flag necessary? 1792172 4 cdumez 2021-09-09 17:04:56 -0700 (In reply to Yusuke Suzuki from comment #3) > (In reply to Chris Dumez from comment #2) > > (In reply to Yusuke Suzuki from comment #1) > > > @Chris > > > I opened > > > https://w3c-test.org/html/infrastructure/safe-passing-of-structured-data/ > > > shared-array-buffers/serialization-via-history.https.html and it said there > > > is no SharedArrayBuffer. > > > Are some headers missing? > > > > I see: > > assert_throws_dom: function "() => { history[method](new > > SharedArrayBuffer(), "dummy title"); }" did not throw > > > > The subtests are failing for me but not due to lack of SharedArrayBuffer > > support. > > > > From Web Inspector, I can see that the test is serving the COOP+COEP headers: > > Cross-Origin-Embedder-Policy: require-corp > > Cross-Origin-Opener-Policy: same-origin > > > > @Yusuke, I've enabled COOP + COEP by default only very recently.

Oh, I had not correctly enabled the COEP feature.
