Bug 171419

@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?

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?

Oh, I had not correctly enabled the COEP feature. Fixed in https://commits.webkit.org/r282245.
