It does not seem to be appearing in post commit bots though. It looks like this started timing out on EWS around r278788 Ews runs: https://ews-build.webkit.org/#/builders/3?numbuilds=300 History: https://results.webkit.org/?suite=api-tests&test=TestWebKitAPI.WebKit.AudioBufferSize 1769955 1 webkit-bug-importer 2021-06-15 14:06:28 -0700 <rdar://problem/79360787> 1769957 2 cdumez 2021-06-15 14:16:07 -0700 r278788 is a logging patch so it is unlikely to be the cause? + Eric / Jer as this is an API test that was fairly recently introduced by them (r277876). 1769962 3 tsavell 2021-06-15 14:34:13 -0700 Thanks Chris! I didn't think r278788 started the issue, just where I first saw it fail on EWS. It would seem likely then that this API test has been failing sense introduction in r277876 1769977 4 cdumez 2021-06-15 15:23:59 -0700 I don't know much about this particular test but if it relies on the GPUProcess, it might also be related to the following flaky crash that is still occurring on our bots: stderr: ASSERTION FAILED: isInRoutingArbitrationForToken(token) || m_setupArbitrationOngoing ./platform/audio/mac/SharedRoutingArbitrator.mm(123) : void WebCore::SharedRoutingArbitrator::endRoutingArbitrationForToken(const WebCore::SharedRoutingArbitrator::Token &) 1 0x100f29ec0 WTFCrash 2 0x11d9f3540 JSC::JSValue::isUndefined() const 3 0x11eb8d5f4 WebCore::SharedRoutingArbitrator::endRoutingArbitrationForToken(WebCore::SharedRoutingArbitrator::Token const&) 4 0x10aa650f4 WebKit::AudioSessionRoutingArbitratorProxy::endRoutingArbitration() 5 0x1093c13f8 void IPC::callMemberFunctionImpl<WebKit::AudioSessionRoutingArbitratorProxy, void (WebKit::AudioSessionRoutingArbitratorProxy::*)(), std::__1::tuple<> >(WebKit::AudioSessionRoutingArbitratorProxy*, void (WebKit::AudioSessionRoutingArbitratorProxy::*)(), std::__1::tuple<>&&, std::__1::integer_sequence<unsigned long>) 6 0x1093c0f30 void IPC::callMemberFunction<WebKit::AudioSessionRoutingArbitratorProxy, void (WebKit::AudioSessionRoutingArbitratorProxy::*)(), std::__1::tuple<>, std::__1::integer_sequence<unsigned long> >(std::__1::tuple<>&&, WebKit::AudioSessionRoutingArbitratorProxy*, void (WebKit::AudioSessionRoutingArbitratorProxy::*)()) 7 0x1093bd53c void IPC::handleMessage<Messages::AudioSessionRoutingArbitratorProxy::EndRoutingArbitration, WebKit::AudioSessionRoutingArbitratorProxy, void (WebKit::AudioSessionRoutingArbitratorProxy::*)()>(IPC::Decoder&, WebKit::AudioSessionRoutingArbitratorProxy*, void (WebKit::AudioSessionRoutingArbitratorProxy::*)()) 8 0x1093bd2b8 WebKit::AudioSessionRoutingArbitratorProxy::didReceiveMessage(IPC::Connection&, IPC::Decoder&) 9 0x109959c78 IPC::MessageReceiverMap::dispatchMessage(IPC::Connection&, IPC::Decoder&) 10 0x10a9b09e4 WebKit::AuxiliaryProcessProxy::dispatchMessage(IPC::Connection&, IPC::Decoder&) 11 0x10ac9f3b8 WebKit::WebProcessProxy::didReceiveMessage(IPC::Connection&, IPC::Decoder&) 12 0x10941a428 IPC::Connection::dispatchMessage(IPC::Decoder&) 13 0x10941ab70 IPC::Connection::dispatchMessage(std::__1::unique_ptr<IPC::Decoder, std::__1::default_delete<IPC::Decoder> >) 14 0x109419118 IPC::Connection::dispatchIncomingMessages() 15 0x10943dbf8 IPC::Connection::enqueueIncomingMessage(std::__1::unique_ptr<IPC::Decoder, std::__1::default_delete<IPC::Decoder> >)::$_12::operator()() 16 0x10943db00 WTF::Detail::CallableWrapper<IPC::Connection::enqueueIncomingMessage(std::__1::unique_ptr<IPC::Decoder, std::__1::default_delete<IPC::Decoder> >)::$_12, void>::call() 17 0x100f53498 WTF::Function<void ()>::operator()() const 18 0x100fd6ffc WTF::RunLoop::performWork() 19 0x100fdbd28 WTF::RunLoop::performWork(void*) 1770016 5 ryanhaddad 2021-06-15 16:44:47 -0700 I couldn't find any TestWebKit API crashes lining up with then timeouts on one of the bots I checked, so I can't confirm it is related to that assert. 1770295 6 eric.carlson 2021-06-16 11:27:21 -0700 This was caused by r278784 1770301 7 431574 eric.carlson 2021-06-16 11:40:16 -0700 Created attachment 431574 Patch 1770684 8 ews-feeder 2021-06-17 09:34:27 -0700 Committed r278990 (238916@main): <https://commits.webkit.org/238916@main> All reviewed patches have been landed.
