Bug 259677

http/wpt/cache-storage/cache-quota-after-restart.any.html

This test is a flaky failure on macOS and iOS, constant failure on x86 (GTK/WPE/Wayland).

HISTORY:

https://results.webkit.org/?suite=layout-tests&test=http%2Fwpt%2Fcache-storage%2Fcache-quota-after-restart.any.html

TEXT DIFF:

-CONSOLE MESSAGE: Cache API operation failed: Quota exceeded
 CONSOLE MESSAGE: Cache API operation failed: Quota exceeded

 PASS After network process restart, verify quota is computed according space being used
-PASS After network process restart, verify quota is computed according space being used and does not increase
+FAIL After network process restart, verify quota is computed according space being used and does not increase assert_unreached: Should have rejected: put should fail Reached unreachable code

REPRODUCIBILITY:

I was able to reproduce this bug on macOS Ventura ToT running the test as follows:

run-webkit-tests --iterations 500 --verbose http/wpt/cache-storage/cache-quota-after-restart.any.html

REGRESSION:

This test has been a flaky/constant failure on the reported platforms as far back in history as the flakiness dashboard extends. From a previous bug report (bug #196197), I was able to identify a potential regression point at the time of test introduction at 210340@main. It is unclear as to whether this included the flaky failures on WK2 or just the reported constant GTK/WPE failures.
