It appears they both started timing out constantly at r277313. Working on reproduction steps. 1760149 1 jenner 2021-05-14 11:27:05 -0700 I have reproduced the timeout at BigSur Debug ToT using the following test: run-api-tests TestWebKitAPI.IPCTestingAPI.CanReceiveIPCSemaphore I was also able to verify the regression point. The timeouts did occur at r277313, but did not occur at r277312. So it appears r277313 caused the regression. 1760151 2 webkit-bug-importer 2021-05-14 11:27:43 -0700 <rdar://problem/78025515> 1760174 3 sam 2021-05-14 13:05:41 -0700 Ok, we just need to update the names of some messages from ImageData to PixelBuffer. These tests are really error prone and will likely see more of this kind of failure if we don’t have a more robust way to catch these failures at compile time or at least better errors when the signatures don’t match at runtime. 1760175 4 428648 sam 2021-05-14 13:07:28 -0700 Created attachment 428648 Patch 1760214 5 ews-feeder 2021-05-14 14:35:40 -0700 Committed r277506 (237737@main): <https://commits.webkit.org/237737@main> All reviewed patches have been landed.
