[Performance Tests] [Qt] jslib-modify-jquery.html and html5-full-render.html are timing out

Summary
[Performance Tests] [Qt] jslib-modify-jquery.html and html5-full-render.html ...

Having any test time out is really bad on perf bots because we let each test run for 10 minutes :( Running Dromaeo/jslib-modify-jquery.html (30 of 44) timeout: PerformanceTests/Dromaeo/jslib-modify-jquery.html FAILED stopping DumpRenderTree timed out, killing it killed Running Parser/html5-full-render.html (40 of 44) timeout: PerformanceTests/Parser/html5-full-render.html FAILED stopping DumpRenderTree timed out, killing it killed

Parser/html5-full-render.html is not timing out for me anymore after the fix we are discussing for
https://bugs.webkit.org/show_bug.cgi?id=79561
. However, Dromaeo/jslib-modify-jquery.html is and I still couldn't find the reason.

I couldn't go much further into it, but here goes a backtrace from gdb (after waiting quite a few minutes running the test) and I will attach a callgrind output that might help. -------------------------------------------------------------------- #0 0x00007ffff68a2c70 in WebCore::RenderInline::culledInlineLastLineBox() const () from /home/jeez/code/webkit/build/webkit2-qt50-debug/Release/lib/libQtWebKit.so.4 #1 0x00007ffff68c7b00 in WebCore::RenderLineBoxList::dirtyLinesFromChangedChild(WebCore::RenderObject*, WebCore::RenderObject*) () from /home/jeez/code/webkit/build/webkit2-qt50-debug/Release/lib/libQtWebKit.so.4 #2 0x00007ffff68c7abc in WebCore::RenderLineBoxList::dirtyLinesFromChangedChild(WebCore::RenderObject*, WebCore::RenderObject*) () from /home/jeez/code/webkit/build/webkit2-qt50-debug/Release/lib/libQtWebKit.so.4 #3 0x00007ffff68e2d2a in WebCore::RenderObjectChildList::appendChildNode(WebCore::RenderObject*, WebCore::RenderObject*, bool) () from /home/jeez/code/webkit/build/webkit2-qt50-debug/Release/lib/libQtWebKit.so.4 #4 0x00007ffff68e102f in WebCore::RenderObject::addChild(WebCore::RenderObject*, WebCore::RenderObject*) () from /home/jeez/code/webkit/build/webkit2-qt50-debug/Release/lib/libQtWebKit.so.4 #5 0x00007ffff68a7a7e in WebCore::RenderInline::addChildIgnoringContinuation(WebCore::RenderObject*, WebCore::RenderObject*) () from /home/jeez/code/webkit/build/webkit2-qt50-debug/Release/lib/libQtWebKit.so.4 #6 0x00007ffff63bb7db in WebCore::NodeRendererFactory::createRendererIfNeeded() () from /home/jeez/code/webkit/build/webkit2-qt50-debug/Release/lib/libQtWebKit.so.4 #7 0x00007ffff63aecbb in WebCore::Node::createRendererIfNeeded() () from /home/jeez/code/webkit/build/webkit2-qt50-debug/Release/lib/libQtWebKit.so.4 #8 0x00007ffff63dea79 in WebCore::Text::attach() () from /home/jeez/code/webkit/build/webkit2-qt50-debug/Release/lib/libQtWebKit.so.4 #9 0x00007ffff6358f34 in WebCore::ContainerNode::attach() () from /home/jeez/code/webkit/build/webkit2-qt50-debug/Release/lib/libQtWebKit.so.4 #10 0x00007ffff638e89b in WebCore::Element::attach() () from /home/jeez/code/webkit/build/webkit2-qt50-debug/Release/lib/libQtWebKit.so.4 #11 0x00007ffff639591e in WebCore::Element::recalcStyle(WebCore::Node::StyleChange) () from /home/jeez/code/webkit/build/webkit2-qt50-debug/Release/lib/libQtWebKit.so.4 #12 0x00007ffff6395553 in WebCore::Element::recalcStyle(WebCore::Node::StyleChange) () from /home/jeez/code/webkit/build/webkit2-qt50-debug/Release/lib/libQtWebKit.so.4 #13 0x00007ffff6395553 in WebCore::Element::recalcStyle(WebCore::Node::StyleChange) () from /home/jeez/code/webkit/build/webkit2-qt50-debug/Release/lib/libQtWebKit.so.4 #14 0x00007ffff6379b5b in WebCore::Document::recalcStyle(WebCore::Node::StyleChange) () from /home/jeez/code/webkit/build/webkit2-qt50-debug/Release/lib/libQtWebKit.so.4 #15 0x00007ffff6379fb3 in WebCore::Document::updateStyleIfNeeded() () from /home/jeez/code/webkit/build/webkit2-qt50-debug/Release/lib/libQtWebKit.so.4 #16 0x00007ffff67fc2d2 in WebCore::ThreadTimers::sharedTimerFiredInternal() () from /home/jeez/code/webkit/build/webkit2-qt50-debug/Release/lib/libQtWebKit.so.4 #17 0x00007ffff079a642 in QObject::event (this=0x6b5140, e=0x7fffffffdb80) at kernel/qobject.cpp:995 #18 0x00007ffff1d0fc7c in QApplicationPrivate::notify_helper (this=0x679380, receiver=0x6b5140, e=0x7fffffffdb80) at kernel/qapplication.cpp:3716 #19 0x00007ffff1d0d312 in QApplication::notify (this=0x7fffffffe060, receiver=0x6b5140, e=0x7fffffffdb80) at kernel/qapplication.cpp:3175 #20 0x00007ffff0765eca in QCoreApplication::notifyInternal (this=0x7fffffffe060, receiver=0x6b5140, event=0x7fffffffdb80) at kernel/qcoreapplication.cpp:699 #21 0x00007ffff0769be1 in QCoreApplication::sendEvent (receiver=0x6b5140, event=0x7fffffffdb80) at kernel/qcoreapplication.h:206 #22 0x00007ffff07cd592 in QTimerInfoList::activateTimers (this=0x65a420) at kernel/qtimerinfo_unix.cpp:613 #23 0x00007ffff07ce759 in timerSourceDispatch (source=0x65a3c0) at kernel/qeventdispatcher_glib.cpp:186 #24 0x00007ffff07ce840 in idleTimerSourceDispatch (source=0x65a470) at kernel/qeventdispatcher_glib.cpp:233 #25 0x00007ffff32438bd in g_main_context_dispatch () from /usr/lib/libglib-2.0.so.0 #26 0x00007ffff32440b8 in ??

After Qt5 update we get results and it is killed in the same time: Running Dromaeo/jslib-modify-jquery.html (30 of 44) RESULT Dromaeo: jslib-modify-jquery= 6957.57172878 ms median= 0.0 ms, stdev= 190.170680721 ms, min= 6434.96364789 ms, max= 7367.90516633 ms Finished: 203.632039 s stopping DumpRenderTree timed out, killing it killed How is it possible?
