Summary [GTK] Lots of WebGL2 tests are flaky
Carlos Alberto Lopez Perez
Reported 2023-02-24 07:47:24 PST
Since the WebGL2 tests were activated at 259348@main lot of them have started to cause unexpected errors. Some of this tests are really really flaky. To the point they are causing issues on the EWS bots. I have seen some runs where some of this WebGL2 tests fail with patch (a patch totally unrelated to this). When the bot repeats the failure 11 times the test fails 11 times Then the bot builds without patch And then the test passes 11 times Something weird is going on with this tests. It is not normal that they can give 11 times a failure on a row and then 11 times a pass on another row. It looks like if the flakiness was decided at build-time rather than a run-time (either you got a build that is going to fail always or always going to pass). So the result doesn't change until you rebuild or something like that. Just speculation on my part here. Example of runs where I saw this: https://ews-build.webkit.org/#/builders/35/builds/42754 https://ews-build.webkit.org/#/builders/35/builds/42758 https://ews-build.webkit.org/#/builders/35/builds/42761 https://ews-build.webkit.org/#/builders/35/builds/42768 https://ews-build.webkit.org/#/builders/35/builds/42780 https://ews-build.webkit.org/#/builders/35/builds/42809 https://ews-build.webkit.org/#/builders/35/builds/42818 https://ews-build.webkit.org/#/builders/35/builds/42838 https://ews-build.webkit.org/#/builders/35/builds/42876 https://ews-build.webkit.org/#/builders/35/builds/42883 https://ews-build.webkit.org/#/builders/35/builds/42907 https://ews-build.webkit.org/#/builders/35/builds/42917 https://ews-build.webkit.org/#/builders/35/builds/42933 https://ews-build.webkit.org/#/builders/35/builds/42934 https://ews-build.webkit.org/#/builders/35/builds/42953 https://ews-build.webkit.org/#/builders/35/builds/42969 https://ews-build.webkit.org/#/builders/35/builds/42977 https://ews-build.webkit.org/#/builders/35/builds/42978 https://ews-build.webkit.org/#/builders/35/builds/42993 https://ews-build.webkit.org/#/builders/35/builds/43002 https://ews-build.webkit.org/#/builders/35/builds/43010 https://ews-build.webkit.org/#/builders/35/builds/43044 https://ews-build.webkit.org/#/builders/35/builds/43050 https://ews-build.webkit.org/#/builders/35/builds/43054 https://ews-build.webkit.org/#/builders/35/builds/43066 https://ews-build.webkit.org/#/builders/35/builds/43072 https://ews-build.webkit.org/#/builders/35/builds/43083 https://ews-build.webkit.org/#/builders/35/builds/43089 https://ews-build.webkit.org/#/builders/35/builds/43121 I initially gardened some of this at 260776@main but I missed a few them. I'm going to add all of the ones that I detected are failing in an upcoming gardening patch On WPE the issue happens also but much less often than in GTK.

Just speculation on my part here. > Could be something also related to clean build issues like: the build-only bot is creating builds that fail because a bug that triggers due to a continous-build issue but the test-only bot creates build that work because it is doing continous builds from a further point. In any case the gardening done here is just based on the info from the post-commit bots (not the EWS) ones so I believe there is something else going here than just a 'clean build' issue. I also checked the info from other post-commit bots like the skip-failing tests one and they report same issue (lots of flakies).

Closing as duplicated. Let's use bug 251107 to track the flakies and failures for WebGL2 tests *** This bug has been marked as a duplicate of bug 251107 ***
