I believe thee is more then one underlying issue. For example, tests that fail with "CONSOLE MESSAGE: line 3: JavaScript execution exceeded timeout." - seems this is legit since JSC workers are terminated by setting a 1-ms timeout. V8 workers terminate by throwing exception of a special kind and then checking for it in C++ code. In JCS case, we likely should disable the message once WorkerThread::stop() was invoked.
I'm trying to catch one elusive crash for some time now. It's in Chromium but perhaps it's the same thing. It manifests like this: ASSERTION FAILED: !m_sharedBuffer (/b/slave/mac/build/src/third_party/WebKit/WebCore/WebCore.gyp/../platform/text/StringImpl.cpp:59 WebCore::StringImpl::~StringImpl()) or like this: Test: worker-cloneport.html Chromium Helper(1774,0xb00a1000) malloc: *** error for object 0x241e260: double free *** set a breakpoint in malloc_error_break to debug Chromium Helper(1774,0xb00a1000) malloc: *** error for object 0x241e280: incorrect checksum for freed object - object was probably modified after being freed. There is some race going on... But not frequent enough to easily find it :-( Dmitry On Mon, Mar 29, 2010 at 4:54 PM, Eric Seidel <[email protected]> wrote: > It seems Workers makes for a disproportionate number of crashes and > flaky tests on the bots: > > https://bugs.webkit.org/show_bug.cgi?id=36646 (timeout) > https://bugs.webkit.org/show_bug.cgi?id=36633 (crash) > https://bugs.webkit.org/show_bug.cgi?id=36585 (timeout) > https://bugs.webkit.org/show_bug.cgi?id=29926 (crash) > https://bugs.webkit.org/show_bug.cgi?id=29090 (timeout) > https://bugs.webkit.org/show_bug.cgi?id=34281 (timeout) > https://bugs.webkit.org/show_bug.cgi?id=33653 (crash) > https://bugs.webkit.org/show_bug.cgi?id=33437 (crash) > https://bugs.webkit.org/show_bug.cgi?id=33008 (crash) > > I have not tried running a full run-webkit-tests with --guard, but I > suspect there may be some sort of memory smasher or other corruption > problem which has been flying under our radar for a long while. > > Unfortunately I don't know more than that yet... > > -eric > _______________________________________________ > webkit-dev mailing list > [email protected] > http://lists.webkit.org/mailman/listinfo.cgi/webkit-dev >
