Earlier we use to restrict admins, moderators or members of a group to
manage that group if they were part of the realm wide
`can_manage_all_groups`. We will not do that anymore and even
non-members of a group regardless of role can manage a group if they are
part of `can_manage_all_groups`.
See
https://chat.zulip.org/#narrow/stream/101-design/topic/Group.20add.20members.20dropdown/near/1952902
to check more about the migration plan for which this is the last step.
Fixes#25942.
Users with permission to manage the group (either on the group level or
realm level) should be able to add members to the group without being
present in can_add_members_group.
Removing members will be controlled by `can_manage_group` until we add
`can_remove_members_group` in the future.
Users with permission to manage a group can add members to that group by
default without being present in `can_add_members_group`.
Earlier, only public data export was possible via `POST /export/realm`
endpoint. This commit adds support to create full data export with
member consent via that endpoint.
Also, this adds a 'export_type' parameter to the dictionaries
in `realm_export` event type and `GET /export/realm` response.
Fixes part of #31201.
The user groups, fetched to send events when deactivating or
reactivating a user, are ordered by ID so that we can avoid
flaky behavior in tests when verifying event details in
test_do_deactivate_user and test_do_reactivate_user tests in
test_events.py.
Document setting the keys that will send a message or create a new
line when composting a message via the compose box and via the
personal settings overlay.
Updates links and redirect from former help center article about
this feature.
Fixes#31620.
This commit updates backend code to not allow adding deactivated
users to groups including when creating groups and also to not
allow removing deactivated users from groups.
There is no behavioral changes to deactivated users as we do
not create UserMessage rows or call the notification code path
for deactivated users in a user group mention. But it is better
to not include the deactivated users in fields like
"mention_user_ids", so this commit updates the code to not
include deactivated users in the computed mention data.
This commit updates code to not include deactivated users in the
anonymous group settings data sent to clients, where the setting
value is sent as a dict containing members and subgroups of the
anonymous group.
This commit updates code to not include deactivated users in
members list in the user groups object sent in "/register"
and "GET /user_groups" response and also in the response
returned by endpoint like "GET /user_groups/{group_id}/members".
The events code is also update to handle this -
- We expect clients to update the members list on receiving
"realm_user/update" event on deactivation. But for guests
who cannot access the user, "user_group/remove_members"
event is sent to update the group members list on deactivation.
- "user_group/add_members" event is sent to all the users on
reactivating the user.
We previously did not update the subscribers list for unsubscribed
and never subscribed streams when a user is deactivated or a
guest user loses access to some user.
For the six realm settings mentioned in the main description of
the /api/update-message endpoint, link back to that page in the
/api/register-queue and /api/get-events endpoints. This way we
can maintain a centralized point of documentation for how these
settings work for message content edits and moving messages.
The descriptions in the events and register pages focuses on the
specifics for each realm setting, e.g., when a value is added or
changed for a particular realm setting.
We show a confirmation dialog explaining the "resolve topics"
feature when the user marks a topic resolved for the first time.
If the user confirms the action, we mark the
topic resolved, else we don't.
We don't show anything the first time a topic is marked
unresolved.
Fixes#31242
Limiting lookups by delivery_email to users with "everyone" email
visibility is overly simplistic. We can successfully do these lookups
whenever the requester has the permission to view the real email address
of the user they're looking up.
This is helpful for taking an "acting user" and getting the list of
email_address_visibility values such that the UserProfiles with those
values of the setting permit the acting user to view their
deliver_email.
This can be used for a query "all users whose delivery_email is viewable
by <requester>" in an upcoming commit.
The added code is ugly, but at least it lets us simplify some similarly
ugly logic in can_access_delivery_email.
Ths hardcoded documentation of which values are possible was destined
to end up inaccurate and out-of-date; and meanwhile, we do have a part
of the API that already has these data in machine-readable format.
This commit updates the 'notify_reaction_update' function to use
the generic 'event_recipient_ids_for_action_on_messages' function.
It helps to add hardening such that if the invariant "no usermessage
row corresponding to a message exists if the user loses access to the
message" is violated due to some bug, it has minimal user impact.
Earlier, submessage was not live-updated for users who joined
the stream after the message was sent.
This commit fixes that bug.
Also, now we use 'event_recipient_ids_for_action_on_messages'.
It helps to add hardening such that if the invariant "no usermessage
row corresponding to a message exists if the user loses access to the
message" is violated due to some bug, it has minimal user impact.
Earlier, we were sending 'delete_message' event to all active
subscribers of the stream.
We shouldn't send event to those users who don't have access
to the deleted message in a private stream with protected history.
This commit fixes that bug.
Also, now we use 'event_recipient_ids_for_action_on_messages'.
It helps to add hardening such that if the invariant "no usermessage
row corresponding to a message exists if the user loses access to the
message" is violated due to some bug, it has minimal user impact.
Added `result_` prefix to differentiate it from upcoming `message_ids`
parameter to the API request. Also, this is final `message_ids` that
we will fetch the messages for. So, a `result` prefix makes sense here.
Earlier, we used to store the key data related to realm exports
in RealmAuditLog. This commit adds a separate table to store
those data.
It includes the code to migrate the concerned existing data in
RealmAuditLog to RealmExport.
Fixes part of #31201.
This commit updates code to store the realm export stats in
json format instead of plain text.
This will help in storing the stats as JsonField in RealmExport table.
This prevents a deadlock between the thumbnailing worker and message
sending, as follows:
1. A user uploads an image, making Attachment and ImageAttachment
rows, as well as enqueuing a job in the thumbnailing queue.
2. Message sending starts a transaction, creates the Message row,
and calls `do_claim_attachments`, which edits the Attachment row
of the upload (implicitly locking it).
3. The thumbnailing worker starts a transaction, locks the
ImageAttachment row for its image, thumbnails it, and then
attempts to `select_for_update()` the message objects (joined to
the Attachments table) to find the ones which link to the
attachment in question. This query blocks, since "a locking
clause without a table list affects all tables used in the
statement"[^1] and the message-send request already has a write
lock on the Attachments row in question.
4. The message-send request attempts to re-fetch the ImageAttachment
row inside the transaction, which tries to pull a lock on it.
5. Deadlock, because the message-send request has the Attachment
lock, and waits for the ImageAttachment lock; the thumbnailing
worker has the ImageAttachment lock, and waits for the Attachment
lock.
We break this deadlock by limiting the
`update_message_rendered_content` `select_for_update` to only take
the lock on the Message table, and not also the Attachments table --
no changes will be made to the Attachments, so no lock is necessary
there. This allows the thumbnailing worker to successfully pull the
empty list of messages (since the message-send request has not
commits its transaction, and thus the Message row is not visible
yet), and release its ImageAttachment lock so that the message-send
request can proceed.

This better simulates the Slack API, which is important, since some
integrations check this response and decide whether the Slack endpoint
is working based on what they receive.
These files are necessary for the protocol to verify that the file
upload was completed successfully. Rather than delete them, we update
their StorageClass if it is non-STANDARD.
Because the main indexes on end_time either don't include realm_id or
do include subgroup, passing an explicit subgroup=None for
single-realm queries to read CountStats that don't use the subgroups
feature greatly improves the query plans.
We create an unnamed user group with just the group creator as it's
member when trying to set the default. The pattern I've followed across
most of the acting_user additions is to just put the user declared
somewhere before the check_add_user_group and see if the test passes.
If it does not, then I'll look at what kind of user it needs to be set
to `acting_user`.
