LayoutTest webgl/1.0.2/conformance/glsl/misc/shader-with-reserved-words.html is a flaky timeout https://webkit-test-results.webkit.org/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=webgl%2F1.0.2%2Fconformance%2Fglsl%2Fmisc%2Fshader-with-reserved-words.html
I need to see if there are any code changes that can be blamed. Otherwise, these timeouts may have started after the macOS bots had the latest OS / security updates installed.
Marked test as flaky on mac-wk1 debug in https://trac.webkit.org/changeset/215879/webkit
I do not see any obviously related changes before https://trac.webkit.org/changeset/215359/webkit that may explain this. The test was a flaky timeout before, but the frequency has greatly increased.
The Test has now started to be flaky on debug Wk2 as well. This does not appear to be a recent change. The oldest timeout on the dashboard was on 4/19/2017: https://build.webkit.org/builders/Apple%20Sierra%20Debug%20WK2%20(Tests)/builds/565 Diff: --- /Volumes/Data/slave/sierra-debug-tests-wk2/build/layout-test-results/webgl/1.0.2/conformance/glsl/misc/shader-with-reserved-words-expected.txt +++ /Volumes/Data/slave/sierra-debug-tests-wk2/build/layout-test-results/webgl/1.0.2/conformance/glsl/misc/shader-with-reserved-words-actual.txt @@ -1,5 +1,5 @@ -This test runs the WebGL Test listed below in an iframe and reports PASS or FAIL. +#PID UNRESPONSIVE - com.apple.WebKit.WebContent.Development (pid 80242) +FAIL: Timed out waiting for notifyDone to be called -Test: ../../../resources/webgl_test_files/conformance/glsl/misc/shader-with-reserved-words.html -PASS - +#EOF +#EOF
