Description David Kilzer (:ddkilzer) 2020-01-14 21:13:40 PST
http/tests/appcache/main-resource-redirect-with-sw.html is a flakey crash, mostly on iOS Simulator.

Flakiness dashboard:  <https://webkit-test-results.webkit.org/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=http%2Ftests%2Fappcache%2Fmain-resource-redirect-with-sw.html>

This flakey crash was also seen on the first run for the ios-wk2 test bot for Bug 205368 Attachment #387728 [details]:
Run:  <https://ews-build.webkit.org/#/builders/24/builds/8501>
Results:  <https://ews-build.webkit.org/results/iOS-13-Simulator-WK2-Tests-EWS/r387728-8501/results.html>

I couldn't find a crash log looking at recent crashes in test failures, though.

This test flaked in https://ews-build.webkit.org/#/builders/24/builds/8900 as well, crashed in layout-tests step, while in subsequent re-run-layout-tests step it passed. Unnecessarily slowing down that ews build.

This test was added in https://trac.webkit.org/changeset/229086/webkit

Recently flaked in following builds (crashed in layout-tests step, while in subsequent re-run-layout-tests step it passed):

https://ews-build.webkit.org/#/builders/24/builds/9004
https://ews-build.webkit.org/#/builders/24/builds/9001
https://ews-build.webkit.org/#/builders/24/builds/8986
Comment 6 Alexey Proskuryakov 2020-01-22 14:15:37 PST
Looking at results from a single run, I see a lot of ServiceWorker test crashes: https://build.webkit.org/results/Apple%20iPadOS%2013%20Simulator%20Debug%20WK2%20(Tests)/r254829%20(1083)/results.html

None of them have crash logs or anything interesting in stdio.

Youenn, which is the master bug fo tracking these?
