This commit adds code to not include original details of senders like
name, email and avatar url in the message objects sent through events
and in the response of endpoint used to fetch messages.
This is the last major commit for the project to add support for
limiting guest access to an entire organization.
Fixes#10970.
Earlier, the event sent when an onboarding step (hotspot till now)
is marked as read generated an event with type='hotspots' and
'hotspots' named array in it.
This commit renames the type to 'onboarding_steps' and the array
to 'onboarding_steps' to reflect the fact that it'll also contain
data for elements other than hotspots.
This commit adds a new endpoint 'users/me/onboarding_steps'
deprecating the older 'users/me/hotspots' to mark hotspot as read.
We also renamed the view `mark_hotspot_as_read` to
`mark_onboarding_step_as_read`.
Reason: Our plan is to make this endpoint flexible to support
other types of UI elements not just restricted to hotspots.
This commit adds code to not allow Zulip Cloud organizations that are not
on the Plus plan to change the "can_access_all_users_group" setting.
Fixes#27877.
Guests might lose access to deactivated users if the user
is not involved in any DM with guest. This commit adds
code to send "realm_user/remove" events for such cases.
We now send user creation events to recipient users
when sending DMs if recipients gain access to either
sender or other pariticpating users in the DM.
This commit adds code to send "realm_user/remove" event
when a guest user loses access to a user due to the user
being unsubscribed from one or more streams.
This commit adds code to send user creation events to
guests who gain access to new subscribers and to the
new guest subscribers who gain access to existing
stream subscribers.
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.
This commit adds code to make sure that update events for changing
a user's role, email, etc. are not sent to guests who cannot access
the modified user.
We do not send the original user data in user creation events
to guests if user access is restricted in realm, as they would
receive the information about user if user is subscribed to some
common streams after account creation.
This commit adds code to send stream deletion events when
unsubscribing non-admin users from private streams and
when unsubscribing guests from public streams since
non-admins cannot access unsubscribed private streams
and guests cannot access unsubscribed public streams.
This commit removes "email_address" field from Subscription objects
and we would instead a new endpoint in next commit to get email
address for stream with proper access check.
This change also fixes the bug where we would include email address
for the unsubscribed private stream as well when user did not have
permission to send message to the stream, and having email allowed
the unsubscribed user to send message to the stream.
Note that the unsubscribed user can still send message to the stream
if the user had noted down the email before being unsubscribed
and the stream token is not changed after unsubscribing the user.
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.
This commit moves constants for system group names to a new
"SystemGroups" class so that we can use these group names
in multiple classes in models.py without worrying about the
order of defining them.
Previous behavior-
- Guest did not receive stream creation events for new
web-public streams.
- Guest did not receive peer_add and peer_remove events
for web-public and subscribed public streams.
This commit fixes the behavior to be -
- Guests now receive stream creation events for new
web-public streams.
- Guest now receive peer_add and peer_remove events for
web-public and subscribed public streams.
This commit renames default_view and escape_navigates_to_default_view
settings to web_home_view and web_escape_navigates_to_home_view in
database and API to match with our recent renaming of user facing
strings related to this.
We also rename the variables, functions, comments in code and class
names and IDs for elements related to this.
This commit adds two user settings, named
* `automatically_follow_topics_policy`
* `automatically_unmute_topics_in_muted_streams_policy`
The settings control the user's preference on which topics they
will automatically 'follow' or 'unmute in muted streams'.
The policies offer four options:
1. Topics I participate in
2. Topics I send a message to
3. Topics I start
4. Never (default)
There is no support for configuring the settings through the UI yet.
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.
Updates the testing for draft event schemas to be fully checked by
`zerver/tests/test_events.py` and `tools/check-schema`.
Also, corrects the type for the timestamp field in Draft objects
in the OpenAPI documentation.
Updates the testing for scheduled message event schemas to be fully
checked by `zerver/tests/test_events.py` and `tools/check-schema`.
Adds the missing 'failed' field to the scheduled message events
in `web/tests/lib/events.js` as well.
Adds support for bulk-adjusting a single user's membership in multiple
user groups in a single transaction in the low-level actions
functions, for future use by work on #9957.
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.
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.

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.
This commit removes the stray values, i.e., [1, 2, 3], used
in the tests for desktop_icon_count_display.
We use 'UserProfile.DESKTOP_ICON_COUNT_DISPLAY_CHOICES' instead.
'test_change_user_settings' in 'UserDisplayActionTest' excludes
the notification settings and tests only the display settings.
The code block excluding the notification settings doesn't exclude
'modern_notification_settings'. It only excludes the
'notification_settings_legacy'.
This commit replaces 'notification_settings_legacy' with
'notification_setting_types', which consists of all the
notification settings.
This demonstrates the use of BaseModel to replace a check_dict_only
validator.
We also add support to referring to $defs in the OpenAPI tests. In the
future, we can descend down each object instead of mapping them to dict
for more accurate checks.
This commit does the backend changes required for adding a realm
setting based on groups permission model and does the API changes
required for the new setting `Who can create multiuse invite link`.
We now send stream creation and stream deletion events on
changing a user's role because a user can gain or lose
access to some streams on changing their role.
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.
**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.
