1269436 - Always pass the principal to push observer notifications

Status: RESOLVED FIXED

(Core :: DOM: Push Subscriptions, defect)

Description

[Lina Butler [:lina]]

Attachment: pushObserverPrincipals.patch

It occurred to me that we don't pass the subscription principal to any of the push observers. I suspect this might be an issue when we eventually start using origin attributes (like `userContextId`).

"push-subscription-change" and "push-subscription-refresh" don't currently have a subject, so we can pass the principal directly to them.

"push-message" takes an optional nsIPushMessage; for that case, I think we'll want to change nsIPushMessage to a wrapper, and pass the actual data as an attribute. JS callers need to null-check and QI to nsIPushMessage, anyway, so I don't think this makes things any more complicated.

we could use  NS_ENSURE_ARG_POINTER here?

Good call, thanks! Added NS_ENSURE_ARG{_POINTER} to the other methods, too. Carrying r+ forward.

I had to rename "nsIPushMessageData" to "nsIPushData," since it conflicts with the refcount tracing for the WebIDL interface: https://treeherder.mozilla.org/logviewer.html#?job_id=20274692&repo=try It's also shorter. :-)
