We had client-side notification stacking in the tray since launch, but now we want to stack notifications in the notifications page, in API responses and in email bundles.
We've seen some cases of deadlock when processing notifications, because
locks are gathered on the users in different orders. Let's try sticking
to a consistent order instead, which should cause the jobs to serialize
rather than deadlock.
Is confusing since "source" already captures the origin of the notifications. It's
needed to interpret things at rendering time, so we can query things as needed there.
Instead of delegating. With a polymorphic relationship, relying on a certain
attribute implies doing things like aliasing "mentioner" to "creator" or similar.
This provides a way to set the level of involvement that a user has with
a collection, and from which we determine the level of notifications to
send. Users can be access-only, watching, or being notified about
everything.
If you're access-only, you won't get an notifications. If you're
watching, you'll only get notifications for the items you're watching
(which includes the items you've been assigned, have commented on, etc).
If you're set to everything you'll get notifications about all activity
in that collection.
This change replaces our previous concept of subscriptions. Where
previously you'd subscribe to a collection to get notifications in it,
now you'll simply set the notification level on your access.
