	nsIPushErrorReporter.idl	Ack types, reported when the Push service acknowledges an incoming message. Acks are sent before the message is dispatched to the service worker, since the server delays new messages until all outstanding ones have been acked. \|reportDeliveryError\| will be called if an error occurs in the worker's `push` event handler after acking the message.	1685	-
	nsIPushNotifier.idl	Fires XPCOM observer notifications and service worker events for messages sent to push subscriptions.	3947	-
	nsIPushService.idl	A push subscription, passed as an argument to a subscription callback. Similar to the `PushSubscription` WebIDL interface.	5819	-
	Push.manifest		156	-
	Push.sys.mjs	The Push component runs in the child process and exposes the Push API to the web application. The PushService running in the parent process is the one actually performing all operations.	9550	-
	PushBroadcastService.sys.mjs	Convert the listeners from our on-disk format to the format needed by a hello message.	8692	-
	PushComponents.sys.mjs	This file exports XPCOM components for C++ and chrome JavaScript callers to interact with the Push service.	13443	-
	PushCrypto.sys.mjs	Localized error property names.	25790	-
	PushDB.sys.mjs	@param aRecord The record to be added.	13304	-

	PushManager.h	PushManager and PushSubscription are exposed on the main and worker threads. The main thread version is implemented in Push.js. The JS implementation makes it easier to use certain APIs like the permission prompt and Promises. Unfortunately, JS-implemented WebIDL is not supported off the main thread. To work around this, we use a chain of runnables to query the JS-implemented nsIPushService component for subscription information, and return the results to the worker. We don't have to deal with permission prompts, since we just reject calls if the principal does not have permission. On the main thread, PushManager wraps a JS-implemented PushManagerImpl instance. The C++ wrapper is necessary because our bindings code cannot accomodate "JS-implemented on the main thread, C++ on the worker" bindings. PushSubscription is in C++ on both threads since it isn't particularly verbose to implement in C++ compared to JS.	4363	100 %
	PushNotifier.cpp		14401	90 %
	PushNotifier.h	`PushDispatcher` is a base class used to forward observer notifications and service worker events to the correct process.	5159	44 %
	PushRecord.sys.mjs	The push subscription record, stored in IndexedDB.	9371	-
	PushService.sys.mjs	State is change only in couple of functions: init - change state to PUSH_SERVICE_INIT if state was PUSH_SERVICE_UNINIT changeServerURL - change state to PUSH_SERVICE_ACTIVATING if serverURL present or PUSH_SERVICE_INIT if not present. changeStateConnectionEnabledEvent - it is call on pref change or during the service activation and it can change state to PUSH_SERVICE_CONNECTION_DISABLE changeStateOfflineEvent - it is called when offline state changes or during the service activation and it change state to PUSH_SERVICE_ACTIVE_OFFLINE or PUSH_SERVICE_RUNNING. uninit - change state to PUSH_SERVICE_UNINIT.	50422	-
	PushServiceWebSocket.sys.mjs	A proxy between the PushService and the WebSocket. The listener is used so that the PushService can silence messages from the WebSocket by setting PushWebSocketListener._pushService to null. This is required because a WebSocket can continue to send messages or errors after it has been closed but the PushService may not be interested in these. It's easier to stop listening than to have checks at specific points.	38484	-
