Patch

r=me if the bots are happy.
Comment 5 Alexey Proskuryakov 2019-03-21 20:10:44 PDT
Looks like at least a retry is needed, as the patch failed to apply on several important bots.
Comment 6 Alex Christensen 2019-03-22 09:11:19 PDT
The patch failed to apply on some bots because I had already committed this to https://trac.webkit.org/changeset/243345/webkit once I saw that it built on all platforms and passed tests

Comment 8 Truitt Savell 2019-03-22 10:40:30 PDT
It looks like the changes in https://trac.webkit.org/changeset/243345/webkit

has caused legacy-animation-engine/animations/resume-after-page-cache.html

to become a flakey timeout and more consistent failure.

History:
https://webkit-test-results.webkit.org/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=legacy-animation-engine%2Fanimations%2Fresume-after-page-cache.html

I was able to reproduce with command:

run-webkit-tests legacy-animation-engine/animations/resume-after-page-cache.html --iterations 100 -f --force

the test does not timeout on 243345 and does on 243346
Comment 9 Truitt Savell 2019-03-22 10:49:54 PDT
animations/resume-after-page-cache.html is also timing out.

Comment 10 Shawn Roberts 2019-03-25 16:01:49 PDT
It looks like the changes in https://trac.webkit.org/changeset/243345/webkit

is causing the following tests to fail around 75% of the time on Mac and iOS Simulator WK2 and Debug

http/tests/cache-storage/cache-records-persistency.https.html (was marked flaky previously on Mac)
http/tests/cache-storage/cache-clearing-origin.https.html

Dashboard :

https://webkit-test-results.webkit.org/dashboards/flakiness_dashboard.html?tests=http%2Ftests%2Fcache-storage%2Fcache-records-persistency.https.html+performance-api%2Fperformance-observer-periodic.html+scrollingcoordinator%2Fios%2Fui-scroll-fixed.html+storage%2Findexeddb%2Fmodern%2Fidbtransaction-objectstore-failures-private.html#showAllRuns=true&tests=http%2Ftests%2Fcache-storage%2Fcache-records-persistency.https.html%20http%2Ftests%2Fcache-storage%2Fcache-clearing-origin.https.html

Prior to change the tests were still flaky failures, but after this change they have about a 75% failure rate.

Reproduced with :

run-webkit-tests http/tests/cache-storage/cache-records-persistency.https.html http/tests/cache-storage/cache-clearing-origin.https.html --iterations 100 --child-process 1 --ios-simulator --exit-after-n-failures=10 --no-retry

Ignore the above comment. It looks like I'm blaming the wrong revision.
