Bug 1587794 - Add a test that verifies we don't crash on a disconnected global. r=perry
Because this seems fairly Gecko-specific, I've put this in our mozilla-specific WPT dir. This is as opposed to writing this as a mochitest. If I run this test without the fix, the browser crashes. If I run it with the fix, we pass. I run the test via ./mach wpt testing/web-platform/mozilla/tests/service-workers/update_completes_in_disconnected_global.https.html Note that currently because of https://bugzilla.mozilla.org/show_bug.cgi?id=1587463#c13 I had to comment out the lsan_dir lines I refer to there locally to get the test to run. Depends on D49671 Differential Revision: https://phabricator.services.mozilla.com/D49672 --HG-- extra : moz-landing-system : lando
