Description Robert Jenner 2023-06-09 10:37:26 PDT

TestWebKitAPI.ApplicationStateTracking.WindowDeallocDoesNotPermanentlyFreezeLayerTree

is a constant timeout. It appears to only run on iOS, so it is a timeout only on iOS. 

HISTORY:
https://results.webkit.org/?suite=api-tests&test=TestWebKitAPI.ApplicationStateTracking.WindowDeallocDoesNotPermanentlyFreezeLayerTree

There's a very clear regression point, appearing to start at 264920@main. Will confirm.

Comment 2 Robert Jenner 2023-06-09 11:41:53 PDT

I was able to reproduce the timeout at iOS 16 Release ToT running as follows:

run-api-tests --release --verbose --ios-simulator TestWebKitAPI.ApplicationStateTracking.WindowDeallocDoesNotPermanentlyFreezeLayerTree

I was also able to bisect and determine that https://commits.webkit.org/264920@main was what introduced this test failure.
