imported/w3c/web-platform-tests/service-workers/service-worker/extendable-event-async-waituntil.https.html is very flaky due to that. See https://build.webkit.org/results/Apple%20High%20Sierra%20Debug%20WK2%20(Tests)/r227533%20(1762)/results.html for instance. 1392794 2 beidson 2018-01-24 15:03:20 -0800 Taking a look 1392842 3 beidson 2018-01-24 16:44:58 -0800 I absolutely cannot reproduce no matter how I stress test my WKTR. That said, I can see how this can happen in SW-land where calls to entangle and disentangle are coming in from different processes. 1 - Web process sends a "disentangle" message to the UI process 2 - Web process sends a postMessage to the StorageProcess with the port as a payload. 3 - Storage process forwards that message along to the SW process with the payload. 4 - ServerWorker process gets the message and then sends the UI process the "entangle" message For some reason the disentangle sent in #1 is slow to go out - and in fact not even received by the UI process for awhile. And then #2, #3, and #4 happen pretty quickly. In this scenario the #4 entangle is received before the #1 disentangle, triggering the ASSERT (Note, it also means the disentangle will come in later in a release build and wreck havoc, rendering messages undeliverable) Bummer. If we move to a model where the UI process *is* the storage process, this would actually go away. (That's obviously not the short term fix) 1393069 4 webkit-bug-importer 2018-01-25 09:17:25 -0800 <rdar://problem/36871207> 1399921 5 334048 cdumez 2018-02-16 10:04:18 -0800 Created attachment 334048 Patch 1399942 6 334048 commit-queue 2018-02-16 11:05:11 -0800 Comment on attachment 334048 Patch Clearing flags on attachment: 334048 Committed r228564: <https://trac.webkit.org/changeset/228564> 1399943 7 commit-queue 2018-02-16 11:05:13 -0800 All reviewed patches have been landed.
