C++ (Cpp) WorkerContext::stopActiveDOMObjects Examples

Example #1

    virtual void performTask(ScriptExecutionContext *context)
    {
        ASSERT(context->isWorkerContext());
        WorkerContext* workerContext = static_cast<WorkerContext*>(context);

#if ENABLE(DATABASE)
        // We currently ignore any DatabasePolicy used for the document's
        // databases; if it's actually used anywhere, this should be revisited.
        DatabaseTaskSynchronizer cleanupSync;
        workerContext->stopDatabases(&cleanupSync);
#endif

        workerContext->stopActiveDOMObjects();

        // Event listeners would keep DOMWrapperWorld objects alive for too long. Also, they have references to JS objects,
        // which become dangling once Heap is destroyed.
        workerContext->removeAllEventListeners();

#if ENABLE(DATABASE)
        // We wait for the database thread to clean up all its stuff so that we
        // can do more stringent leak checks as we exit.
        cleanupSync.waitForTaskCompletion();
#endif

        // Stick a shutdown command at the end of the queue, so that we deal
        // with all the cleanup tasks the databases post first.
