Aman Agrawal 9fc6b93347 user_settings: Add option to configure channel click behavior.
This commit does not implement the setting's behavior, just the API
change and settings UI.

roanster007 52692a6448 refactor: Rename `huddle` to `direct_message_group` in non API.
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

Lauryn Menard 673a01ea0c realm-deactivation: Send email to owners as part of deactivation.
Creates a new "realm_deactivated" email that can be sent to realm
owners as part of `do_deactivate_realm`, via a boolean flag,
`email_owners`.

This flag is set to `False` when `do_deactivate_realm` is used for
realm exports or changing a realm's subdomain, so that the active
organization owners are not emailed in those cases.

This flag is optional for the `deactivate_realm` management command,
but as there is no active user passed in that case, then the email
is sent without referencing who deactivated the realm.

It is passed as `True` for the support analytics view, but the email
that is generated does not include information about the support
admin user who completed the request for organization deactivation.

When an active organization owner deactivates the organization, then
the flag is `True` and an email is sent to them as well as any other
active organization owners, with a slight variation in the email text
for those two cases.

Adds specific tests for when `email_owners` is passed as `True`. All
existing tests for other functionality of `do_deactivate_user` pass
the flag as `False`.

Adds `localize` from django.util.formats as a jinja env filter so
that the dates in these emails are internationlized for the owner's
default language setting in the "realm_deactivated" email templates.

Fixes #24685.

Sahil Batra 6164a41864 realm: Remove create_private_stream_policy setting.
This commit removes create_private_stream_policy setting as
we now use new group based setting.

The "/register" response includes realm_create_private_stream_policy
field to return a value representing superset of users who have the
permission to create private channels, as older clients still expect
this field.

Sahil Batra dea62a3fd9 events: Pass realm to fetch_initial_state_data always.
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.

Sahil Batra 222995b1be settings: Remove create_public_stream_policy.
This commit removes create_public_stream_policy setting
since public channel creation permissions are now handled
by group-based setting.

We still pass "realm_create_public_stream_policy" in
"/register" response though for older clients with its
value being set depending on the value of group based
setting. If we cannot set its value to an appropriate
enum corresponding to the group setting, then we set
it to "Members only" considering that server will not
allow the users without permissions to create public
channels but the client can make sure that UI is
available to the users who have permission.

This commit also adds a test in test_events for the case when
first_message_id of a stream is updated on deleting a message.

Sahil Batra aa84080ad6 tests: Add a helper function to create anonymous groups.
This commit adds a new helper function to create or update

user IDs and subgroup IDs which we can skip in tests.

Sahil Batra 81765a1e83 user_groups: Fix audit log data when changing group settings.
This commit fixes the code store correct old value in audit
log data when changing can_mention_group setting from a
anonymous group to another anonymous group. The bug was
because the old value was being computed after updating
the UserGroup object with new members and subgroups and
is fixed by computing the old value for all the cases
and passing it to do_change_user_group_permission_setting.

Prakhar Pratyush c798d192dc message_send: Update do_send_messages codepath to send event on commit.
Earlier, we were using 'send_event' & 'queue_json_publish' in

events but the transaction fails at a later stage.

Events should not be sent until we know we're not rolling back.

  to reactivate their realm via a self-serve flow (e.g.
  "owner_request") vs where we can't (ToS abuse).

be used to subscribe the new users to the default streams at the
time of account creation and not to the streams that were default

Prakhar Pratyush 61e606f656 onboarding: Remove 'core team' private channel.
We no longer create the 'core team' private channel when

populate_db still creates the 'core team' channel to
represent a private channel.

Alex Vandiver d863aa56de invites: Lock the realm when determining invitation counts.
This prevents users from hammering the invitation endpoint, causing
races, and inviting more users than they should otherwise be allowed
to.

Doing this requires that we not raise InvitationError when we have
partially succeeded; that behaviour is left to the one callsite of
do_invite_users.

Alex Vandiver 0079688c49 tornado: Drop WebReloadClientError logic.
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.

This is preparatory work towards adding a Topic model.

Currently, we use *topic as the local variable name for

We rename local variables of the form *topic to *topic_name
so that we don't need to think about type collisions in
individual code paths where we might want to talk about both
Topic objects and strings for the topic name.

We now send "realm_user/update" (and "realm_bot/update" for bots)
events with "is_active" field when deactivating and reactivating
users, including bots.

We would want to use "remove" event for a user losing access
to another user for #10970, so it is better to use "update"
event for deactivation as we only update "is_active" field
in the user objects and the clients still have the data for
deactivated users.

Previously, we used to send "add" event for reactivation along
with complete user objects, but clients should have the data
for deactivated users as well, so an "update" event is enough
like we do when deactivating users.

Prakhar Pratyush c349d1137c sent_by_human: Add "test suite" to the set of Zulip UI-style clients.
Earlier, when we used 'self.send_message()' in the backend tests,
the sent message was not marked as read for the sender.

Reason: To set the read flag, we have to check if
'message.sent_by_human()'. It returns False because the
'sending_client' for tests is "test suite" and the 'sent_by_human'
function doesn't enlist the "test suite" client name as a human client.

This commit adds "test suite" to that list.

Also fixes a bug in when apply_unread_message_event was called that
was revealed by this change.

Prakhar Pratyush 49092dfa79 unread_msgs: Fix all unreads in muted stream being treated as muted.
Earlier, 'is_row_muted' returned 'true' if the message was in
a muted stream or muted topic.

If the message is in an unmuted or followed topic in a muted
stream, such topics should be treated as not muted topics
in an unmuted stream.

This commit fixes the incorrect behavior.

Now, for wildcard mentions, 'unread_msgs.mentions' exclude
the IDs in muted streams only if the message is in default or
muted topic.

Also, 'unread_msgs.count' takes into account the unreads in unmuted
or followed topics in muted streams too.

Documents that this bug was fixed in the API changelog.

Hemant Umre be653dd5b4 org_settings: Add backend for `realm_jitsi_server_url` setting.
This commit adds a `jitsi_server_url` field to the Realm model, which
will be used to save the URL of the custom Jitsi Meet server. In
the database, `None` will encode the server-level default. We can't
readily use `None` in the API, as it could be confused with "field not
sent". Therefore, we will use the string "default" for this purpose.

We have also introduced `server_jitsi_server_url` in the `/register`
API. This will be used to display the server's default Jitsi server
URL in the settings UI.

The existing `jitsi_server_url` will now be calculated as
`realm_jitsi_server_url || server_jitsi_server_url`.

Fixes a part of #17914.

Prakhar Pratyush db8229ae32 test_events: Separate tests for send and update message events.
This is a prep commit to separate the single test
'test_stream_send_message_events' into two separate tests named
'test_stream_send_message_events' & test_stream_update_message_events'
to verify the events related to send and update message, respectively.

As a part of introducing two new user settings
* 'automatically_follow_topics_policy'
* 'automatically_unmute_topics_policy'
in the next commit, we will extend 'test_stream_send_message_events'.

This logical separation helps in avoiding a single, super-long test.

Anders Kaseorg 6988622fe8 ruff: Enable B023 Function definition does not bind loop variable.
Python’s loop scoping is misdesigned, resulting in a very common
gotcha for functions that close over loop variables [1].  The general
problem is so bad that even the Go developers plan to break
compatibility in order to fix the same design mistake in their
language [2].

Enable the Ruff rule function-uses-loop-variable (B023) [3], which
conservatively prohibits functions from binding loop variables at all.

Sahil Batra 5e1eb3cd44 events: Fix applying stream creation events in apply_event.
There was a bug in apply_event code where only a stream which
is not private is added to the "never_subscribed" data after
a stream creation event. Instead, it should be added to the
"never_subscribed" data irrespective of permission policy of
the stream as we already send stream creation events only to
those users who can access the stream. Due to the current
bug, private streams were not being added to "never_subscribed"
data in apply_event for admins as well. This commit fixes it
and also makes sure the "never_subscribed" list is sorted
which was not done before and was also a bug.

The bugs mentioned above were unnoticed as the tests did not
cover these cases and this commit also adds tests for those
cases.

Zixuan James Li a081428ad2 user_groups: Make locks required for updating user group memberships.
**Background**

User groups are expected to comply with the DAG constraint for the
many-to-many inter-group membership. The check for this constraint has
to be performed recursively so that we can find all direct and indirect
subgroups of the user group to be added.

This kind of check is vulnerable to phantom reads which is possible at
the default read committed isolation level because we cannot guarantee
that the check is still valid when we are adding the subgroups to the
user group.

**Solution**

To avoid having another transaction concurrently update one of the
to-be-subgroup after the recursive check is done, and before the subgroup
is added, we use SELECT FOR UPDATE to lock the user group rows.

The lock needs to be acquired before a group membership change is about
to occur before any check has been conducted.

Suppose that we are adding subgroup B to supergroup A, the locking protocol
is specified as follows:

1. Acquire a lock for B and all its direct and indirect subgroups.
2. Acquire a lock for A.

For the removal of user groups, we acquire a lock for the user group to
be removed with all its direct and indirect subgroups. This is the special
case A=B, which is still complaint with the protocol.

**Error handling**

We currently rely on Postgres' deadlock detection to abort transactions
and show an error for the users. In the future, we might need some
recovery mechanism or at least better error handling.

**Notes**

An important note is that we need to reuse the recursive CTE query that
finds the direct and indirect subgroups when applying the lock on the
rows. And the lock needs to be acquired the same way for the addition and
removal of direct subgroups.

User membership change (as opposed to user group membership) is not
affected. Read-only queries aren't either. The locks only protect
critical regions where the user group dependency graph might violate
the DAG constraint, where users are not participating.

**Testing**

We implement a transaction test case targeting some typical scenarios
when an internal server error is expected to happen (this means that the
user group view makes the correct decision to abort the transaction when
something goes wrong with locks).

To achieve this, we add a development view intended only for unit tests.
It has a global BARRIER that can be shared across threads, so that we
can synchronize them to consistently reproduce certain potential race
conditions prevented by the database locks.

The transaction test case lanuches pairs of threads initiating possibly
conflicting requests at the same time. The tests are set up such that exactly N
of them are expected to succeed with a certain error message (while we don't
know each one).

**Security notes**

get_recursive_subgroups_for_groups will no longer fetch user groups from
other realms. As a result, trying to add/remove a subgroup from another
realm results in a UserGroup not found error response.

We also implement subgroup-specific checks in has_user_group_access to
keep permission managing in a single place. Do note that the API
currently don't have a way to violate that check because we are only
checking the realm ID now.

Zixuan James Li 30495cec58 migration: Rename extra_data_json to extra_data in audit log models.
This migration applies under the assumption that extra_data_json has
been populated for all existing and coming audit log entries.

- This removes the manual conversions back and forth for extra_data
throughout the codebase including the orjson.loads(), orjson.dumps(),
and str() calls.

- The custom handler used for converting Decimal is removed since
DjangoJSONEncoder handles that for extra_data.

- We remove None-checks for extra_data because it is now no longer
nullable.

- Meanwhile, we want the bouncer to support processing RealmAuditLog entries for
remote servers before and after the JSONField migration on extra_data.

- Since now extra_data should always be a dict for the newer remote
server, which is now migrated, the test cases are updated to create
RealmAuditLog objects by passing a dict for extra_data before
sending over the analytics data. Note that while JSONField allows for
non-dict values, a proper remote server always passes a dict for
extra_data.

- We still test out the legacy extra_data format because not all
remote servers have migrated to use JSONField extra_data.
This verifies that support for extra_data being a string or None has not
been dropped.

Zixuan James Li 37660dd0e7 linkifier: Support reordering linkifiers.
This adds API support to reorder linkifiers and makes sure that the
returned lists of linkifiers from `GET /events`, `POST /register`, and
`GET /realm/linkifiers` are always sorted with the order that they
should processed when rendering linkifiers.

We set the new `order` field to the ID with the migration. This
preserves the order of the existing linkifiers.

New linkifiers added will always be ordered the last. When reordering,
the `order` field of all linkifiers in the same realm is updated, in
a manner similar to how we implement ordering for
`custom_profile_fields`.

Lauryn Menard 195e5b8dc1 events: Add test to remove existing value for custom profile field.
Adds a test for when a value for a user's custom profile field is
removed and not set to a new value. The omission of this event in
the tests was noted as a possibility in #22103, which updated the
API documentation for these events having `null` for the field
value.

When adding the test discovered that the events logic was not
deleting the field from the user object and instead setting it to
`None`, so fixes that logic as well. There was a similar bug fixed
in commit 96c61a1a41 for when custom profile fields are removed
from a realm.

Sahil Batra ae72151ec1 streams: Pass stream_weekly_traffic field in stream objects.
This commit adds code to pass stream traffic data using
the "stream_weekly_traffic" field in stream objects.

We already include the traffic data in Subscription objects,
but the traffic data does not depend on the user to stream
relationship and is stream-only information, so it's better
to include it in Stream objects. We may remove the traffic
data and other stream information fields for Subscription
objects in future.

This will help clients to correctly display the stream
traffic data in case where client receives a stream
creation event and no subscription event, for an already
existing stream which the user did not have access to before.
