We do not fetch all the realm group settings using
select_related for register data now since it takes a
lot of time in planning phase. This commit updates
the code to fetch all the members and subgroups data
in user_groups_in_realm_serialized so that we do not
need to access each setting group individually.
user_groups_in_realm_serialized is updated to send the
required data accordingly.
Fixes#33656.
Following improvments are done in user_groups_in_realm_serialized-
- Members and subgroups are fetched using a single query using
union.
- Query to fetch groups now does not fetch setting fields since
we already have the members and subgroups of all the setting
groups and we can check if setting group was a named group
or not directly without checking named_user_group field of
UserGroup object as we have IDs of all named groups of the realm.

Non realm admin users were not able to view private channels they were
an administrator of but not subscribed to it. This commit changes that.
We also made changes for those users to be able to see the subscribers
list.
The increase in query count in test_home and test_event_system can be
mitigated by only fetching recursive user group ids when needed within
the `validate_user_access_to_subscribers_helper` function. But that
would require refactoring that function to handle multiple streams and
subscriptions at once, along with changing how that function is used at
different places, which might be an exercise better left as a follow up.
We have optimised the code a little bit by not fetching the group ids in
case the current user is a realm admin.
We are fetching channel_admin_ids and users belonging to
can_add_subscribers_group directly in stream_subscription.py without
using the helper function
`get_user_ids_with_metadata_access_via_permission_groups`. This is due
to a cyclic dependency and we will move `bulk_get_subscriber_peer_info`
to another file in the next commit.
This commit is a part of the work to support empty string
as a topic name.
Previously, empty string was not a valid topic name.
Adds backward compatibility for topic names in `unread_msgs`
objects returned in `/register` response.
This commit is a part of the work to support empty string
as a topic name.
Previously, empty string was not a valid topic name.
Adds a `empty_topic_name` client capability to allow client
to specify whether it supports empty string as a topic name.
Adds backward compatibility for:
- `subject` field in the `message` event type
The stream and subscription objects now have stream_post_policy value
set according to the can_send_message_group setting representing the
superset of users who have permission to post in the channel.
For an incoming 1:1 DM, the recipient’s own recipient_id is useless to
the recipient themselves. Substitute the sender’s recipient_id, so the
recipient can use recipient_id as documented to uniquely represent the
set of 2 users in this conversation.

We already have fetched all the groups that the user is
member of, so we can just check if can_invite_users_group
is included in that list of groups like we do for similar
fields like can_create_public_streams, etc.
This helps us in saving a DB query.
Fixes#32408.
This commit extends the test for the `/api/v1/register` endpoint
for spectator users by adding an assertion to check the number
of database queries.
Fixes: #32409
This commit refactors code in user_groups_in_realm_serialized
such that we do not prefetch "can_mention_group__direct_members"
and "can_mention_group__direct_subgroups" using prefetch_related
and instead fetch members and subgroups for all groups in separate
queries and then use that data to find the members and subgroups
of the group used for that setting.
This change helps us in avoiding two prefetch queries for each
setting when we add more group settings.
Earlier, we were using 'send_event' in
'notify_realm_custom_profile_fields' which can lead to a situation,
if any db operation is added after the 'send_event' in the action
functions using it, where we enqueue event 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.
In 'fetch_initial_state_data' we were doing one database query
per announcement stream.
This commit updates the logic to prefetch those streams using
select_related hence avoiding the extra db queries.
Fixes#28909.
Currently, for computing fields like can_create_public_streams
and can_create_private_steams fields, is_user_in_group is called
to check whether the user is part of the group which has the
permission. This means that there will be one DB query for each
field.
To optimize this, we now first fetch all the groups that the
user is member of, including the anonymous groups which are
used for settings, such that we can then just check whether
the user is part of the group which has the permission meaning
we would need only one query to compute all the fields.
This would be helpful when settings for other similar fields
will also be migrated to groups framework.
This commit helps in using the realm object which has the
prefetched group settings so that we can avoid extra queries
when calculating fields like can_create_public_streams.
Before this commit, 3 DB queries were actually needed for "realm"
event type but the test mentioned 1 because, the related stream
setting fields were already fetched when testing the case for all
event types above it.
So, when testing the query count for only "realm" event type the
cached realm object was used and no extra queries were made for
the stream settings.
This commit updates the test to refetch the realm before testing
each event type separately, so that we test the actual query count.
This commit updates code to prefetch realm group settings like
"can_create_public_channel_group" only when computing settings
for "/register" response by refetching the realm object with
select_related instead of fetching those settings in UserProfile
query.
This change is done because we do not need to prefetch these
settings for every UserProfile object and for most of the cases
where these settings are actually accessed, we can afford extra
query like when checking permission to create streams. But we
cannot afford one query extra for each setting when computing
these settings for "/register" response, so we re-fetch the
realm object with select_related leading to only one extra
query.
The query count changes in tests are -
- Query count increases by 1 when calling fetch_initial_state_data
for computing can_create_public_streams because Realm object from
UserProfile does not have prefetched setting fields.
- Query count increases by one in test_subs where streams are
created which is as expected due to the setting not being prefetched.
- Query count increases by 2 in tests in test_home.py where one
query is to refetch the realm object and one for computing
can_create_public_streams as mentioned above.
This commit makes passing realm mandatory to fetch_initial_state_data.
This is a prep commit for refetching the realm object with
select_related for group setting fields so that extra queries
can be avoided when computing "/registe" response.
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.
We no longer create the 'core team' private channel when
a realm is created.
Earlier, "New user announcements" channel was set to the
"core team" channel. Now it is disabled by default.
populate_db still creates the 'core team' channel to
represent a private channel.
The naming `uri` is deprecated while `url` should be used in order to
satisfy URL standards. For this reason, four endpoints are affected:
* The response content of three endpoints `/server_settings`,
`/register` and `/realm` that contain a field `realm_uri` is
changed to `realm_url`.
* In one of the common fields for all mobile push notifications payloads,
`realm_url` field is now added as an alias to `realm_uri`.
For backwards compatibility, we keep the field `realm_uri` and add
an alias `realm_url`.

This commit adds a realm-level setting named
'zulip_update_announcements_stream' that configures the
stream to which zulip updates should be posted.
Fixes part of #28604.
The widening of the time between when a process is marked for
reload (at Tornado startup) and when it sends reload events makes it
unlikely-to-impossible that a single `/` request will span both of
them, and thus hit the WebReloadClientError corner case.
Remove it, as it is not worth the complication. The bad behaviour it
is attempting to prevent (of a reload right after opening `/`) was
always still possible -- if the `/` request completed right before
Tornado restarted -- so it is not clear that it was ever worth the
complication.
Collapsing was done incorrectly, as 65c400e06d added `zulip_version`
and `zulip_feature_level`, but did not update the virtual event logic
to copy those new values into the virtual event.
However, it is unlikely that a server will be upgraded multiple times
in quick enough succession for this to ever be relevant. Remove the
logic, which is additional complication for little or no gain.
