This is valuable so that one is forced to explicitly make a decision
on what is correct when adding new callers. Past experience tells us that
not having to explicitly show the decision leads to people introducing
security bugs in PRs that the maintainer has to catch in review, and our
goal for access control code should be that security bugs are hard to write.
Fixes#33688.
We remove `invite_to_stream_policy` from the backend wherever applicable
except deleting the field. We have just ported the existing behaviour of
`invite_to_stream_policy` to `can_add_subscribers_group` except one
change. We have added an explicit exception for admins to have this
permission whether they are part of this group or not. The reason for
this is we are adding `stream.can_add_susbcribers_group` in the future
which will grant all admins permission to subscribe other users to a
channel given they have access to a channel. So it makes sense that we
add this exception to the realm level property also.

b4fedaa765 introduced
this helper, and I assume that the weird loop over
zip made sense at the time.
The assertEqual approach on the whole
set gives nice messages in modern Python.
Earlier, in 'handle_missedmessage_emails' codepath we were using
'queue_json_publish' which can lead to a situation where we enqueue
events but the transaction fails at a later stage.
Events should not be published until we know we're not rolling back.
Now a failure from assert_json_success and friends shows the full
server-side traceback from the JsonableError that caused the failure,
not just the test-side traceback for `AssertionError: 400 != 200 :
{message}`.

We were using admins group as a hardcoded value for the default of
`can_remove_subscribers_group`, now we use a function to get the value
of the default group.
We create savepoint at a couple of places in backend tests
to avoid rollback due to error raised within test's transaction.
This commit explicitly adds 'savepoint=True' at those places.
This commit renames the 'send_event' function to
'send_event_rollback_unsafe' to reflect the fact that it doesn't
wait for the db transaction (within which it gets called, if any)
to commit and sends event irrespective of commit or rollback.
In most of the cases we don't want to send event in the case of
rollbacks, so the caller should be aware that calling the function
directly is rollback unsafe.
Currently, we want to ask users if they would like to delete their
attachments after they have removed the attachments while editing. These
changes are preparatory changes on the backend to return a list of removed
attachments after the user has removed attachments while editing.
Fixes part of #25525.
Instead of the PUSH_NOTIFICATIONS_BOUNCER_URL and
SUBMIT_USAGE_STATISTICS settings, we want servers to configure
individual ZULIP_SERVICE_* settings, while maintaining backward
compatibility with the old settings. Thus, if all the new
ZULIP_SERVICE_* are at their default False value, but the legacy
settings are activated, they need to be translated in computed_settings
to the modern way.
This commit adds an 'transaction.atomic' decorator to the
'add_subscriptions_backend' view thus making the db operations
within the view atomic and helps to avoid race between events sent.
In tests where we make POST requests to this view, we have
wrapped the API calls with a transaction.atomic() context
manager. It helps us with NOT rolling back the entire test
transaction due to error responses.
In 'test_subs' we were making POST request to add
subscrption using 'self.api_post'.
This commit updates the code to use the test helper
function 'common_subscribe_to_streams' instead.
This prep commit will also help us to avoid adding
'transaction.atomic' context manager to these API calls
individually in the case of error response in the next commit.
This commit performs a sweep on the first batch of non API
files to rename "huddle" to "direct_message_group`.
It also renames variables and methods of type -
"huddle_message" to "group_direct_message".
This is a part of #28640
This commit adds a new helper function to create or update
a UserGroup object for a setting. We could have used existing
update_or_create_user_group_for_setting but that also validates
user IDs and subgroup IDs which we can skip in tests.
Earlier, we were using 'send_event' & 'queue_json_publish' in
'do_send_messages' which can lead to a situation where we enqueue
events but the transaction fails at a later stage.
Events should not be sent until we know we're not rolling back.
This timeout strategy using asynchronous exceptions has a number of
safety caveats (read the docstring!!) and should only be used in very
specific circumstances.
