Pending->Canceling->Killing (WorkerNeverRan) Need to clear WorkerPrivate::mPreStartRunnables Could we call WorkerRunnable::WorkerRun() to release resource? There could be no WorkerGlobalScope... Pending->Running->Closing->Canceling->Killing(WorkerRan) Pending->Running->Canceling->Killing(WorkerRan) When entering “Closing” 1. Keeping receives normal WorkerRunnables 2. Making ParentStatus as Closing 3. Cancel all timeout 4. Don’t clear the main event queue anymore. But we still wait for all SyncLoops be completed. 5. Call WorkerGlobalScope::NoteTerminating() and nsIGlobalObject::DisconnectEventTargetObjects(). 6. Switching to “Canceling” by asking parent thread to call WorkerPrivate::Cancel() When entering “Canceling” 1. Call WorkerGlobalScope::NoteTerminating() 2. Notify StrongWorkerRefs, worker is in “Canceling”, send and complete the corresponding shutdown work right now. 3. Executing all runnables until no normal WorkerRunnables in queue and no WorkerRefs, SyncLoops and children workers 4. Stop receiving normal WorkerRunnables and DisconnectEventTargetObjects of WorkerScope. 4. Entering “Killing” When entering “Killing” 1. We would not notify WorkerRefs anymore. Logically all WorkerRefs should be released in “Canceling” 2. Executing all remaining ControlRunnables 3. Release corresponding resources of Worker on worker thread.
