Server can now send partial data to the client to help in
developement. We don't want this to be widely used right now,
hence no documentation changes have been made.
This will likely be a check on client capability later.
This is a preparatory refactor for migrating the internal structure of
Recipient objects for group DMs to use the DirectMessageGroup type,
not the legacy PERSONAL type. This step has the message-sending code
path check if a DirectMessageGroupe exists and prefer it if available.
It should have no effect in production other than doing a useless
database query for each outgoing DM, since we do not at present ever
create such DirectMessageGroup objects. (It will not add a marginal
database query once the migration is complete, just during this
transition).
This commit updates code to not prefetch can_access_all_users_group
and can_access_all_users_group__named_user_group fields using
select_related. We can just use get_realm_system_groups_name_dict
function to check if setting is set to "Everyone" group when
needed and can avoid unnecessarily fetching groups for every user
query.
Earlier, we used to send a single event for all web-public and public
streams. But public streams can have guests, which means the peer user
ids for each of them can be different based on which guests are
subscribed to which channel.
In the previous code, we were using the last stream id from another loop
to get subscribers, which was causing a lot of non-deterministic
failures in our test, since that stream id could keep on changing.
Moreover, it doesn't make much sense to use that id here.
This commit still keeps around the optimisation for public channels with
non-guest users. It will send one event for all public channels with
non-guest users, one for web public channels and for the rest of the
channels it will send an event for each channel with a different set of
peer user ids.
Removed `is_billing_admin` user property as it is no longer used since
billing permissions are now determined by `can_manage_billing_group`
realm setting.
`deliver_scheduled_emails` tries to deliver the email synchronously,
and if it fails, it retries after 10 seconds. Since it does not track
retries, and always tries the earliest-scheduled-but-due message
first, the worker will not make forward progress if there is a
persistent failure with that message, and will retry indefinitely.
This can result in excessive network or email delivery charges from
the remote SMTP server.
Switch to delivering emails via a new queue worker. The
`deliver_scheduled_emails` job now serves only to pull deferred jobs
out of the table once they are due, insert them into RabbitMQ, and
then delete them. This limits the potential for head-of-queue
failures to failures inserting into RabbitMQ, which is more reasonable
than failures speaking to a complex external system we do not control.
Retries and any connections to the SMTP server are left to the
RabbitMQ consumer.
We build a new RabbitMQ queue, rather than use the existing
`email_senders` queue, because that queue is expected to be reasonably
low-latency, for things like missed message notifications. The
`send_future_email` codepath which inserts into ScheduledEmails is
also (ab)used to digest emails, which are extremely bursty in their
frequency -- and a large burst could significantly delay emails behind
it in the queue.
The new queue is explicitly only for messages which were not initiated
by user actions (e.g., invitation reminders, digests, new account
follow-ups) which are thus not latency-sensitive.

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.
The functionality of gravatar can break anonymity if
the user has had a gravatar account set up previously.
This option allows specifically cloud instances to
have gravatar disabled selectively.
This commit is to use medium-size avatar images when previewing avatars during the copy account settings flow. Before this commit, the avatar images were blurry when using the avatar from an existing account while joining a new realm. Now, the avatar is clear.
Fixes#32604.
This commit allows users to be assigned to custom groups when
inviting them to join Zulip, similar to how channels are handled.
The implementation follows a similar pattern for adding pills,
ensuring consistency, as user groups and channels are parallel
in nature.
Fixes#24365.
The old endpoint for updating a user worked only via user id. Now we add
a different entry to this functionality, fetching the user by
.delivery_email.
update_user_backend becomes the main function handling all the logic,
invoked by the two endpoints.
This adds a new special UserProfile flag can_change_user_emails(disabled
by default) and the ability for changing the email address of users in
the realm via update_user_backend. This is useful for allowing
organizations to update user emails without needing to set up a SCIM
integration, but since it gives the ability to hijack user accounts, it
needs to be behind this additional permission and can't be just given to
organization owners by default. Analogical to how the
create_user_backend endpoint works.
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.
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 new property allows organization administrators to specify whether
users can modify the custom profile field value on their own account.
This property is configurable for individual fields.
By default, existing and newly created fields have this property set to
true, that is, they allow users to edit the value of the fields.

Adds a check for changing an existing guest user's role before
calling do_update_user in the case that a realm has a current
paid plan with manual license management.
bulk fetch query of UserPfrofile against which
user_ids are validated, instead of looping
over user_ids and fetchingeach UserPfrofile resulting
in O(n) queries.
This commit updates the Welcome Bot's initial
direct message content.
We inform about the tracked onboarding messages
via direct message only if it exists.
Fixes#30051.
Hash the salt, user-id, and now avatar version into the filename.
This allows the URL contents to be immutable, and thus to be marked as
immutable and cacheable. Since avatars are served unauthenticated,
hashing with a server-side salt makes the current and past avatars not
enumerable.
This requires plumbing the current (or future) avatar version through
various parts of the upload process.
Since this already requires a full migration of current avatars, also
take the opportunity to fix the missing `.png` on S3 uploads (#12852).
We switch from SHA-1 to SHA-256, but truncate it such that avatar URL
data does not substantially increase in size.
Fixes: #12852.
To improve onboarding experience following onboarding
messages are marked as starred:
* First message in each onboarding topic.
* Initial DM sent by Welcome bot
Note: The onboarding topic messages needs to be tracked
in 'OnboardingUserMessage' model to get starred.
Fixes#29298.
We give the user some messages in their feed, so that they can
learn how to use the home view in a realistic way.
For realms having older onboarding messages, we mark the very
most recent messages as unread.
This commit updates the logic to ONLY mark the tracked onboarding
messages (if present) i.e. messages tracked in 'OnboardingUserMessage'
as unread.
Fixes part of #29298.
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
As a follow up for f49a11c810, this
commit standardizes the naming of the day and night themes to light
and dark, respectively in the backend. This makes the backend
consistent with the naming used in the frontend and UI.
This also solves a regression introduced in
f49a11c810, where the frontend was sending
"/light" and "/dark" commands to the backend, but the backend was
expecting "/day" and "/night" commands.
Earlier, a one-time 'visibility_policy_banner' was displayed to
existing as well as new users to inform them about the new
"follow/unmute topics" feature.
It makes sense to educate only the existing Zulip users about
the new feature using this banner. New users don't need to know
about following topics right away.
This commit makes changes to NOT show the banner to new users.
This will also help to avoid banner overload in the new user
experience.
Fixes#30615.
This commit adds include_realm_default_subscriptions parameter
to the invite endpoints and the corresponding field in
PreregistrationUser and MultiuseInvite objects. This field will
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
when sending the invite.
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 previous implementation using Django's `get_or_create` for
`do_increment_logging_stat` involved two separate database queries,
potentially leading to race conditions.
Use an `ON CONFLICT ... DO UPDATE` (aka "upsert") query, which
eliminates race conditions and improves performance. This is mildly
complicated due to the different unique indexes across the various
tables, and the need for bug-for-bug compatibility with the previous
implementation.
Fixes#28947.

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.

This commit updates code to access name from named_user_group
field which points to the "NamedUserGroup" instead of directly
accessing name from "UserGroup", since name field will only
be present on NamedUserGroup objects in further commits.
