- make USE(MULTIPLE_THREADS) support more portable http://bugs.webkit.org/show_bug.cgi?id=13069 - fixed a threadsafety bug discovered by testing this - enhanced threadsafety assertions in collector * API/JSCallbackObject.cpp: (KJS::JSCallbackObject::~JSCallbackObject): This destructor can't DropAllLocks around the finalize callback, because it gets called from garbage collection and we can't let other threads collect! * JavaScriptCore.vcproj/JavaScriptCore/JavaScriptCore.vcproj: * kjs/JSLock.cpp: (KJS::JSLock::currentThreadIsHoldingLock): Added new function to allow stronger assertions than just that the lock is held by some thread (you can now assert that the current thread is holding it, given the new JSLock design). * kjs/JSLock.h: * kjs/collector.cpp: Refactored for portability plus added some stronger assertions. (KJS::Collector::allocate): (KJS::currentThreadStackBase): (KJS::Collector::registerAsMainThread): (KJS::onMainThread): (KJS::PlatformThread::PlatformThread): (KJS::getCurrentPlatformThread): (KJS::Collector::Thread::Thread): (KJS::destroyRegisteredThread): (KJS::Collector::registerThread): (KJS::Collector::markCurrentThreadConservatively): (KJS::suspendThread): (KJS::resumeThread): (KJS::getPlatformThreadRegisters): (KJS::otherThreadStackPointer): (KJS::otherThreadStackBase): (KJS::Collector::markOtherThreadConservatively): (KJS::Collector::markStackObjectsConservatively): (KJS::Collector::protect): (KJS::Collector::unprotect): (KJS::Collector::collectOnMainThreadOnly): (KJS::Collector::markMainThreadOnlyObjects): (KJS::Collector::collect): * kjs/collector.h: * wtf/FastMalloc.cpp: (WTF::fastMallocSetIsMultiThreaded): * wtf/FastMallocInternal.h: * wtf/Platform.h: git-svn-id: http://svn.webkit.org/repository/webkit/trunk@20351 268f45cc-cd09-0410-ab3c-d52691b4dbfc
