The `id` column of `notifications` table and `notification_id` columns
of the other tables have been migrated to bigint in previous commits
(for example, 799a45a).
In order to run the migrations with zero downtime, the data had to be
copied to new columns and swapped, but the old columns have been kept
to allow for rollback. They are no longer needed now.
The `notifications.id` has been migrated to bigint in previous commit
799a45a291. This commit migrates one of
the related columns, `user_badges.notification_id`, to `bigint`.
Currently, only user badge grants emit webhook events. This change
extends the `user_badge` webhook to emit user badge revocation events.
A new `user_badge_revoked` event has been introduced instead of relying
on the existing `user_badge_removed` event. `user_badge_removed` emitted
just the `badge_id` and `user_id` which aren't helpful for generating a
meaningful webhook payload for revoked(deleted) user badges.
The new event emits the user badge object.
This reduces chances of errors where consumers of strings mutate inputs
and reduces memory usage of the app.
Test suite passes now, but there may be some stuff left, so we will run
a few sites on a branch prior to merging
Created two triggers that trigger events when a badge is granted or removed.
Trigger 1:
user_badge_granted
Variable - badge_id
Variable - user_id
Trigger 2:
user_badge_removed
Variable - badge_id
Variable - user_id
