Mac Experimental Retina Release bot failing since 4542 |
||||||
Issue descriptionThe 4541 build had an exception due to sharding resources, but 4540 was at the same angle position, so I don't think 4541 is problematic. 4542 had webgl2_conformance_tests and screenshot_sync_tests fail. Then webgl2_conformance_tests has failed every build since. Some other tests were flaky in the later builds as well such as tab_capture_end2end_tests, context_lost_tests, info_collection_tests and webgl_conformance_tests The 4541-4542 angle changes were https://chromium.googlesource.com/angle/angle/+/00155d58e8b034ecbc179186da8996451fb6de5c Vulkan: Implement scissor test and add a simple test for it https://chromium.googlesource.com/angle/angle/+/b9d1daa06d3519752139d5714210bb43b3d4bec7 Add Vulkan mock_icd to the build These don't seem likely. So maybe a chrome-side change. There's 66 CLs in the one blame range :\ https://ci.chromium.org/buildbot/chromium.gpu.fyi/Mac%20Experimental%20Retina%20Release%20%28AMD%29/4542 https://chromium.googlesource.com/chromium/src/+/88a9ae6d5ab5d0da90cd9b82998ceee86a801b7b Bump Chrome-GPU experimental bots to 10.13.4 Was one of them. Nothing else is standing out for me. What do you think Ken?

Looking at the bot, it is always build210-m1 that's failing with either timeouts and weird errors in the log: https://chromium-swarm.appspot.com/task?id=3b8fa64b799a7210&refresh=10&show_raw=1 TimeoutException: ******************************************************************************** (/b/s/w/ir/third_party/catapult/telemetry/telemetry/internal/backends/chrome_inspector/inspector_backend.py:487 _ConvertExceptionFromInspectorWebsocket) The app is probably crashed: Another early failure had network issues: https://chromium-swarm.appspot.com/task?id=3b8b4d1e50223010&refresh=10&show_raw=1 I'm not sure what we should do with this machine, just restart it?

Ohh I see what you mean, with the sharding. That's an amazing observation.
