885088 - SimplePush recovery mechanism

Status: RESOLVED WONTFIX

(Core :: DOM: Push Subscriptions, defect)

Description

[Guillermo López :willyaranda (probably SLOW response)]

Now:

On hello message, a list of channelIDs is sent if they are registered (or [] if none).

With that, we are doing the initial recovery (register what we do not have, unregister what it is not sent, client always is the final source of truth).

Expected:

On hello message, send the channelIDs with its correspondent version, so we can recover in the server a pair of (channelID, version), and do more optimizations of not sending possible duplicate versions.

This is a small win, so RESOLVED WONTFIX if you do not like it

Extremely low priority since this is an optimization for an unlikely edge case. Needs plausible cases where this might give wins.
