[Bug 20390] New: chromium ipc_tests.exe hangs sometimes on IPCSyncChannelTest.Multiple
http://bugs.winehq.org/show_bug.cgi?id=20390 Summary: chromium ipc_tests.exe hangs sometimes on IPCSyncChannelTest.Multiple Product: Wine Version: 1.1.31 Platform: PC OS/Version: Linux Status: NEW Keywords: download, source, testcase Severity: normal Priority: P2 Component: ntdll AssignedTo: wine-bugs(a)winehq.org ReportedBy: dank(a)kegel.com wine ipc_tests.exe --gtest_filter=IPCSyncChannelTest.Multiple hung on the second run here on wine, but didn't hang in the eight runs I did on Windows. Source for the test is at http://src.chromium.org/viewvc/chrome/trunk/src/ipc/ipc_sync_channel_unittes... though it uses a bunch of classes and will be hard to extract. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.
http://bugs.winehq.org/show_bug.cgi?id=20390 --- Comment #1 from Dan Kegel <dank(a)kegel.com> 2009-10-16 23:35:57 --- To repeat, optionally install the test root cert as described by Juan in bug 20370, then do wget http://kegel.com/wine/chromium/chromium-tests.tar.bz2 tar -xjvf chromium-tests.tar.bz2 more chromium-runtests.sh sh chromium-runtests.sh This runs the base, net, ipc, and unit test suites from Chromium. They all pass on Windows (except for X509CertificateTest.PaypalNullCertParsing, which was broken in this snapshot, and was fixed shortly thereafter). (Once the hangs are fixed, you can do grep FAIL src/chrome/Debug/*tests/run*/*.log to look for failed tests, but those all deserve their own bugs.) -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

I'm still doing it by plopping the cert into the global store as I described in bug 20370. But none of that really matters for the ipc hang.) -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

I'm kind of out of steam for today, here's a brain dump. Running IPCSyncChannelTest.* will hang fairly reliably. IPCSyncChannelTest.Simple hangs about half the time, even if you comment out the second half of IPCSyncChannelTest.Simple. Test shutdown is supposed to go like this: main thread: ~Worker posts call to OnListenerThreadShutdown1, waits listener thread: OnListenerThreadShutdown1 posts call to OnIPCThreadShutdown ipc thread: OnIPCThreadShutdown posts call to OnListenerThreadShutdown2 main thread: wake up, finish. Unfortunately, sometimes the task to call OnIPCThreadShutdown() never gets run. You can see the guts of the task queueing in http://src.chromium.org/viewvc/chrome/trunk/src/base/message_pump_win.cc The task queuer puts the task in the incoming queue, then calls void MessagePumpForIO::ScheduleWork() { if (InterlockedExchange(&have_work_, 1)) return; // Someone else continued the pumping. // Make sure the MessagePump does some work for us. BOOL ret = PostQueuedCompletionStatus(port_, 0, reinterpret_cast<ULONG_PTR>(this), reinterpret_cast<OVERLAPPED*>(this)); DCHECK(ret); } to wake up the consumer, who is sleeping in GetQueuedCompletionStatus(). With winedbg, I can get a good backtrace of the hang (yay pdb support): 4 WaitForSingleObject+0x3c(handle=0x70, timeout=4294967295) [wine-git/dlls/ker nel32/sync.c:129] in kernel32 5 base::WaitableEvent::Wait+0x3c() [src\base\waitable_event_win.cc:62] in ipc_ tests 6 `anonymous namespace'::Worker::~Worker+0xb0() [src\ipc\ipc_sync_channel_unit test.cc:79] in ipc_tests 7 `anonymous namespace'::SimpleClient::~SimpleClient+0x16() in ipc_tests 8 `anonymous namespace'::SimpleClient::`scalar deleting destructor'+0x16() in ipc_tests 9 STLDeleteContainerPointers<std::_Vector_iterator<`anonymous namespace'::Work er *,std::allocator<`anonymous namespace'::Worker *> > >+0x74(begin={}, end={}) [src\base\stl_util-inl.h:67] in ipc_tests 10 `anonymous namespace'::RunTest+0x11c(workers={_Myfirst=0x9bbc70, _Mylast=0x 9bbc78, _Myend=0x9bbc78}) [src\ipc\ipc_sync_channel_unittest.cc:248] in ipc_test s 11 `anonymous namespace'::Simple+0xae(pump_during_send=false) [src\ipc\ipc_syn c_channel_unittest.cc:289] in ipc_tests 12 IPCSyncChannelTest_Simple_Test::TestBody+0x15() [src\ipc\ipc_sync_channel_u nittest.cc:297] in ipc_tests (though I don't *quite* trust the line numbers). A +relay trace of the problem looks kind of like this (with a few extra prints): ... 001f:Ret KERNEL32.CreateEventW() retval=00000070 ret=00472b92 001f:Call KERNEL32.OutputDebugStringA("in ~Worker, created listener_done event handle 0x70") 001f:Call KERNEL32.OutputDebugStringA("in ~Worker, created ipc_done event handle 0x74") 0023:Call KERNEL32.OutputDebugStringA("in OnListenerThreadShutdown1, ipc_event handle 0x74") 0023:Call KERNEL32.InterlockedExchange(009be830,00000001) ret=004bd24d 0023:Ret KERNEL32.InterlockedExchange() retval=00000000 ret=004bd24d 0023:Call KERNEL32.PostQueuedCompletionStatus(000000c0,00000000,009be800,009be80 0) ret=004bd27b 0023:Ret KERNEL32.PostQueuedCompletionStatus() retval=00000001 ret=004bd27b 0044:Ret KERNEL32.GetQueuedCompletionStatus() retval=00000001 ret=004bd899 0044:Call KERNEL32.InterlockedExchange(009be830,00000000) ret=004bda05 0044:Ret KERNEL32.InterlockedExchange() retval=00000001 ret=004bda05 0044:Call KERNEL32.GetQueuedCompletionStatus(000000c0,010be408,010be340,010be334 ,ffffffff) ret=004bd899 001f:Call KERNEL32.OutputDebugStringA(009c0078 "in ~Worker, ipc_thread handle 0xBC id 68") 001f:Call KERNEL32.OutputDebugStringA(009bbed0 "in ~Worker, about to wait on listener_done") 001f:Call KERNEL32.WaitForSingleObject(00000070,ffffffff) ret=00472ffc It's a little hard to trace, since both the server and client side of the test are running in the same process. I tried adding print statements in message_pump_win.cc and rebuilding the test; that worked to some extent, but if I got too aggressive with prints, the hang would go away. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.
