Twice now I have seen multiple test from http/tests/cache/disk-cache/ failing: http/tests/cache/disk-cache/disk-cache-204-status-code.html http/tests/cache/disk-cache/disk-cache-307-status-code.html http/tests/cache/disk-cache/disk-cache-404-status-code.html http/tests/cache/disk-cache/disk-cache-disable.html http/tests/cache/disk-cache/disk-cache-last-modified.html http/tests/cache/disk-cache/disk-cache-media.html http/tests/cache/disk-cache/disk-cache-range.html http/tests/cache/disk-cache/disk-cache-redirect.html http/tests/cache/disk-cache/disk-cache-request-headers.html http/tests/cache/disk-cache/disk-cache-request-max-stale.html http/tests/cache/disk-cache/disk-cache-revalidation-new-expire-header.html http/tests/cache/disk-cache/disk-cache-validation-attachment.html http/tests/cache/disk-cache/disk-cache-validation-back-navigation-policy.html http/tests/cache/disk-cache/disk-cache-vary-cookie.html http/tests/cache/disk-cache/disk-cache-vary-no-body.html http/tests/cache/disk-cache/disk-cache-vary.html http/tests/cache/disk-cache/memory-cache-revalidation-updates-disk-cache.html http/tests/cache/disk-cache/redirect-chain-limits.html http/tests/cache/disk-cache/resource-becomes-uncacheable.html It has happened on two different trains, two different bots and two different configurations. I have yet to be able to reliably reproduce the issue on either El Capitan or Sierra. The test are fairly flaky, but they usually fail together. https://build.webkit.org/builders/Apple%20Sierra%20Debug%20WK2%20(Tests)/builds/1223 https://build.webkit.org/builders/Apple%20El%20Capitan%20Release%20WK2%20(Tests)/builds/1769
On the surface, this sounds much like bug 149087, but the fact that multiple tests fail at once is a difference.
I was able to reproduce a similar failure locally with test http/tests/cache/disk-cache/disk-cache-302-status-code.html I used run-webkit-tests http/tests/cache/disk-cache --no-retry-failures --iterations=10 The tests are very flaky so it doesn't always trigger. diff: --- /Users/mattlewis/buildtotest/layout-test-results/http/tests/cache/disk-cache/disk-cache-302-status-code-expected.txt +++ /Users/mattlewis/buildtotest/layout-test-results/http/tests/cache/disk-cache/disk-cache-302-status-code-actual.txt @@ -10,7 +10,7 @@ response source: Network response headers: {"Status":"302","Location":"/","Cache-control":"max-age=100"} -response source: Network +response source: Disk cache --------Testing loads through memory cache (XHR behavior)-------- response headers: {"Status":"302","Location":"/","Cache-control":"max-age=0"}
This is still happening: https://build.webkit.org/builders/Apple%20iOS%2010%20Simulator%20Release%20WK2%20(Tests)/builds/2467 http/tests/cache/disk-cache/disk-cache-revalidation-new-expire-header.html [ Failure ] http/tests/cache/disk-cache/disk-cache-validation-attachment.html [ Failure ] http/tests/cache/disk-cache/disk-cache-validation-back-navigation-policy.html [ Failure ] http/tests/cache/disk-cache/disk-cache-vary-cookie.html [ Failure ] http/tests/cache/disk-cache/disk-cache-vary-no-body.html [ Failure ] http/tests/cache/disk-cache/disk-cache-vary.html [ Failure ] http/tests/cache/disk-cache/memory-cache-revalidation-updates-disk-cache.html [ Failure ] http/tests/cache/disk-cache/redirect-chain-limits.html [ Failure ] http/tests/cache/disk-cache/resource-becomes-uncacheable.html [ Failure ]
<rdar://problem/32927322>
The test http/tests/cache/disk-cache/disk-cache-vary-cookie.html is now failing with http/tests/cache/disk-cache/redirect-chain-limits.html only Marked http/tests/cache/disk-cache/disk-cache-vary-cookie.html as flaky in: https://trac.webkit.org/changeset/219627/webkit Marked http/tests/cache/disk-cache/redirect-chain-limits.html as flaky in: https://trac.webkit.org/changeset/219629/webkit
This appears resolved. Removing test expectations to restore test coverage.
