These tests are consistently timing out on macOS:

http/tests/appcache/fail-on-update-2.html
http/tests/appcache/remove-cache.html (Monterey wk1 only: when not timing out, this test is constantly failing)

HISTORY:

https://results.webkit.org/?suite=layout-tests&suite=layout-tests&test=http%2Ftests%2Fappcache%2Ffail-on-update-2.html&test=http%2Ftests%2Fappcache%2Fremove-cache.html&platform=mac

REPRODUCIBILITY:

While I was unable to reproduce the timeouts, I was able to reproduce the console stderr output on macOS Monterey (12.6.6, 21G646/arm64) ToT using the following commands:

python3 Tools/CISupport/download-built-product --platform=mac --release 'https://s3-us-west-2.amazonaws.com/archives.webkit.org/mac-monterey-x86_64 arm64-release/270009@main.zip'
python3 Tools/CISupport/built-product-archive --platform=mac-monterey --release extract
python3 Tools/Scripts/run-webkit-tests --no-build --no-show-results --no-new-test-results --clobber-old-results --release --dump-render-tree --results-directory WebKitBuild/layout-test-results --debug-rwt-logging --no-retry-failures http/tests/appcache/fail-on-update-2.html http/tests/appcache/remove-cache.html --iterations 50 --force

REGRESSION:

These tests have been experiencing issues for a while; however, it appears there was a further regression causing the failures on Monterey wk1 between 269858@main and 269860@main.

Comment 2 Alexey Proskuryakov 2023-11-01 10:11:31 PDT 
269859@main seems like a potential culprit then?
