(FR.new.FinalizationRegistry): (tryAgain): Source/JavaScriptCore: This patch adds support for FinalizationRegistries. There are two main parts to this patch, the first is refactoring PromiseTimer a more general into DeferredWorkTimer. This allows us to finally have a "real" setTimeout on the jsc command line. The second part is adding all the new classes needed for FinalizationRegistries. The refactoring is mostly a rename but does two main new things. The first is that it now notifies the VM we have finished a synchronuous JS execution, so that WeakRefs can be collected. The second is that it now catches any exceptions and forwards the to a new method on the global object method table. For WebCore, this reports the exception to the console. For API users, this calls their exceptionHandler block. For the CLI, it exits with exit status 3 (our general exception exit status). Unfortunately, there's not currently an ergonomic way to pass the expected exception from the CLI arguments to this handler so that's not supported here. In order to support FinalizationRegistry this patch adds a "new" class JSDestructibleInternalFieldObjectImpl, which allows us to have a destructible object with internal fields. Since the order of collection doesn't matter we currently use C++ HashTables on the FinalizationRegistry. Since users can unregister objects while the callback is pending we have a hash table for the live entries and a second hash table for the dead ones. Lastly, because users are not requred to provide a token for unregistration we have two extra Vectors containing the live/dead objects that are not unregisterible. * API/JSAPIGlobalObject.cpp: * API/JSAPIGlobalObject.mm: * JavaScriptCore.xcodeproj/project.pbxproj: * Sources.txt: * heap/Heap.cpp: (JSC::Heap::finalizeUnconditionalFinalizers): * jsc.cpp: (functionSetTimeout): (functionFinalizationRegistryLiveCount): (functionFinalizationRegistryDeadCount): (main): (checkUncaughtException): (checkException): (GlobalObject::reportUncaughtExceptionAtEventLoop): (runJSC): * runtime/ArrayIteratorPrototype.cpp: * runtime/CommonIdentifiers.h: * runtime/DeferredWorkTimer.cpp: Renamed from Source/JavaScriptCore/runtime/PromiseTimer.cpp. (JSC::DeferredWorkTimer::DeferredWorkTimer): (JSC::DeferredWorkTimer::doWork): (JSC::DeferredWorkTimer::runRunLoop): (JSC::DeferredWorkTimer::addPendingWork): (JSC::DeferredWorkTimer::hasPendingWork): (JSC::DeferredWorkTimer::hasDependancyInPendingWork): (JSC::DeferredWorkTimer::cancelPendingWork): (JSC::DeferredWorkTimer::scheduleWorkSoon): * runtime/DeferredWorkTimer.h: Renamed from Source/JavaScriptCore/runtime/PromiseTimer.h. * runtime/FinalizationRegistryConstructor.cpp: Added.
