We used 'savepoint=False' in #31169 which was prior to our discussion
in CZO to use 'durable=True' instead.
This commit makes changes to use 'durable=True' in the outermost
transaction.atomic block.
Earlier, we were using 'send_event' in 'do_update_user_status' which
can lead to a situation, if any db operation is added after the
'send_event' in future, where we enqueue events but the action
function fails at a later stage.
Events should not be sent until we know we're not rolling back.
Fixes part of #30489.
The presence and user status update events are only sent to accessible
users, i.e. guests do not receive presence and user status updates for
users they cannot access.
Fourth step in making user status `away` a deprecated way to access
`presence_enabled` for clients supporting older servers, and
checkpoint commit prior to deleting the `status` field from the
UserStatus model.
Part of transitioning from 'unavailable' user status feature to
'invisible mode' user presence feature.
When a user toggles a status update for `away=True|False`, we now update
their `presence_enabled` setting to match (`away!=presence_enabled`).
First step of making user status `away` updates a deprecated way to
access presence_enabled for clients supporting older servers, and
checkpoint commit before migrating users with a current UserStatus
of `status=AWAY` to have their `presence_enabled` set to `False`.
Note that when user status `away` is updated, we now send 4 events:
user_status, user_settings, presence, and update_global_notifications.
Also, this means that these updates change the UserPresence.status
value, which impacts the test for importing and exporting user
information.
Part of transitioning from 'unavailable' user status feature to
'invisible mode' user presence feature.
We need to move this function to a separate actions file specifically
for `user_status` because otherwise we will have a circular import
between `actions/user_settings.py` and `actions/presence.py` in an
upcoming commit.
Prep commit for migrating "unavailable" user status feature to
"invisible" user presence feature.
