The following layout test is a flaky timeout on macOS WK2 http/tests/resourceLoadStatistics/clear-in-memory-and-persistent-store.html Probable cause: This could be related to https://trac.webkit.org/changeset/226235/webkit Flakiness Dashboard: https://webkit-test-results.webkit.org/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=http%2Ftests%2FresourceLoadStatistics%2Fclear-in-memory-and-persistent-store.html

Skipped test in https://trac.webkit.org/changeset/226538/webkit because it is timing out very frequently on the bots.
It seems that after skipping this test another resourceLoadStatistics test began timing out as shown in this bug https://bugs.webkit.org/show_bug.cgi?id=181482 I'm wondering if they are related as both timeout with a failure to have notifyDone called. The diff for this test: --- /Volumes/Data/slave/sierra-debug-tests-wk2/build/layout-test-results/http/tests/resourceLoadStatistics/clear-in-memory-and-persistent-store-expected.txt +++ /Volumes/Data/slave/sierra-debug-tests-wk2/build/layout-test-results/http/tests/resourceLoadStatistics/clear-in-memory-and-persistent-store-actual.txt @@ -1,3 +1,5 @@ -PASS Host classified as prevalent resource. -PASS Host is no longer a prevalent resource after the store was cleared. +#PID UNRESPONSIVE - com.apple.WebKit.WebContent.Development (pid 49276) +FAIL: Timed out waiting for notifyDone to be called +#EOF +#EOF
Hopefully resolved in https://trac.webkit.org/changeset/227223, https://bugs.webkit.org/show_bug.cgi?id=181822.
