We can guarantee this because the add subscriber typeahead (and the
rest of the subscribers tab) is only visible once subscribers have
been loaded.
Work towards #34244.
Now that we're supporting partial subscriber data, we might need
to fetch the full list of subscribers when opening the subscribers
tab of the edit channel modal.
This commit handles a slow load with a loading spinner while we fetch
the data, and also makes sure to ignore the data if it's received after
it stops being relevant (in case the user has another stream's data open).
Work towards #34244
This is the only call to `peer_data.is_subscriber_subset`, so after
this commit all calls to that function work with our new model for
partial subscriber data.
Work towards #34244.
Note that this doesn't show the right counts when the counts appear, because
yet. We can double check functionality after that change is complete.
We have added an ability to partially load subscribers,
and this function name makes it more clear what it returns,
in contrast to an upcoming `get_full_subscriber_set`.
Opening settings and stream settings UI was not working for guests
if they could not access all users. This was because is_person_active
did not handle inaccessible users correctly, if they were not added in
the users data, when being called in get_group_members to render
group pills.
Before this, we were using `is_user_in_setting_group` which does not do
the extra checks around a guest user's permissions (and in future, some
other checks).
We introduced `initialize_and_override_current_user` in stream_data test
to make it easier to set current_user.user_id.
We are making this change with default set as true, since that is the
behaviour other functions are expecting. We are not making any behaviour
changes in this commit on where metadata access should be check or where
content access should be checked for this function's usage. That will be
done commit by commit for different functions using
`can_change_permissions`.
Accepting `require_content_access` makes it a bit hard to read at other
places where the argument is passed as just true or false without
knowing what the argument is for, but it was just a choice when writing
the code. We will refactor this current function into two functions in
the upcoming commits and solve that problem.
We've also removed `can_edit_description` from `stream_data` but we have
kept around `can_change_name_description` in `stream_settings_data`.
Since `can_edit_description` was just used at once place, it didn't make
much sense to keep it around, but we kep around
`can_change_name_description` since we've already done the work to have
fine tuned permissions for that setting and we don't want to undo that
work.
