/**
|
|
* 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.
