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.
It was discovered by the Zulip development team that active users who
had previously been subscribed to a stream incorrectly continued being
able to use the Zulip API to access metadata for that stream. As a
result, users who had been removed from a stream, but still had an
account in the organization, could still view metadata for that
stream (including the stream name, description, settings, and an email
address used to send emails into the stream via the incoming email
integration). This potentially allowed users to see changes to a
stream’s metadata after they had lost access to the stream.
This bug was present in all Zulip releases prior to today's Zulip
Server 7.5.
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.
This commit adds code to unset is_web_public and is_realm_public fields
on attachments when deactivating a stream as we do not want to allow
spectators to access them after the stream is deactivated.
This commit also adds a comment explaining why we don't use
do_change_stream_permission to set the privacy fields on deactivating
a stream.
Fixes#27634.
We did not unset is_realm_public field on attachements when unarchiving
streams, but we do unset is_web_public field. This commit adds code to
unset the is_realm_public field as well as we make the stream private
while unarchiving it.
Rename the existing 'wildcard_mentioned' flag to
'stream_wildcard_mentioned'.
The 'wildcard_mentioned' flag is deprecated and exists for
backwards compatibility.
We have two separate flags for stream and topic wildcard mentions,
i.e., 'stream_wildcard_mentioned' and 'topic_wildcard_mentioned',
respectively.
* stream wildcard mentions: `@all`, `@everyone`, and `@stream`
* topic wildcard mentions: `@topic`
The `wildcard_mentioned` flag is included in the events and
API response if either `stream_wildcard_mentioned` or
`topic_wildcard_mentioned` is set.
The event for stream typing notifications is no longer sent
to the long_term_idle subscribers of the stream.
This helps to reduce the tornado's work of parsing super-long
JSON-encoded lists of user IDs in large streams. Now the lists
are shorter.
Earlier, the 'wildcard_mentioned' flag was set for both the
stream and topic wildcard mentions.
Now, the 'topic_wildcard_mentioned' flag is set for topic
wildcard mentions, and the 'wildcard_mentioned' flag is set for
stream wildcard mentions.
We will rename the 'wildcard_mentioned' flag to
'stream_wildcard_mentioned' in a later commit.
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.
This commit renames permissions_configuration variable to
permission_configuration since the object contains config for
a single permission setting and thus permission_configuration
seems like a better name.
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 updates code in bulk_remove_subscriptions and
bulk_add_subscriptions to return early if there are no
subscribers to remove or add to the streams.
This change helps us in avoiding unnecessary queries like the
one used to get subscribers list of streams, which is then used
to send events but we would not send any events if no subscribers
are added or removed and some more similar queries.
In this commit, we add a new dropdown 'Organization language' on
the `/new` and `/realm/register` pages. This dropdown allows setting
the language of the organization during its creation. This allows
messages from Welcome Bot and introductory messages in streams to be
internationalized.
Fixes a part of #25729.
Add an optional `automatic_new_visibility_policy` enum field
in the success response to indicate the new visibility policy
value due to the `automatically_follow_topics_policy` and
`automatically_unmute_topics_in_muted_streams_policy` user settings
during the send message action.
Only present if there is a change in the visibility policy.
This is a prep commit that extracts the following two methods
from '/actions/scheduled_messages' to reuse in the next commit.
* extract_stream_id
* extract_direct_message_recipient_ids
The 'to' parameter for 'POST /typing' will follow the same pattern
in the next commit as we currently have for the 'to' parameter in
'POST /scheduled_messages', so we can reuse these functions.
This commit replaces the value `private` with `direct` in the
`message_type` field for the `typing` events sent when a user
starts or stops typing a message.
This commit includes the message's sender id in the
'topic_participant_user_ids' set.
The 'participants_for_topic' function doesn't include the sender_id,
if the user is sending their first message in the topic, because
'participants_for_topic' queries the 'Message' table, but the message
is actually sent at a later stage in the codepath, resulting in
missing the sender_id in this case.
This is needed to set the 'wildcard_mentioned' flag for the sender's
user message in the case of topic wildcard mentions.
This doesn't lead to sending email and push notifications to the
sender because we have a check to skip notifications if the user
to receive notifications is the sender itself.
This should have been included in c0c30bc.
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.
This fixes a regression introduced in
9954db4b59, where the realm's default
language would be ignored for users created via API/LDAP/SAML,
resulting in all such users having English as their default language.
The API/LDAP/SAML account creation code paths don't have a request,
and thus cannot pull default language from the user's browser.
We have the `realm.default_language` field intended for this use case,
but it was not being passed through the system.
Rather than pass `realm.default_language` through from each caller, we
make the low-level user creation code set this field, as that seems
more robust to the creation of future callers.
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.
This adds support for syncing user role via the newly added "role"
attribute, which can be set to either of
['owner', 'administrator', 'moderator', 'member', 'guest'].
Removes durable=True from the atomic decorator of do_change_user_role,
as django-scim2 runs PATCH operations in an atomic block.
Matching the topic exactly, as opposed to case-insensitively, is not a
common operation, and one that we want to make difficult to do
accidentally. Inline the single use case of it.
_default_manager is the same as objects on most of our models. But
when a model class is stored in a variable, the type system doesn’t
know which model the variable is referring to, so it can’t know that
objects even exists (Django doesn’t add it if the user added a custom
manager of a different name). django-stubs used to incorrectly assume
it exists unconditionally, but it no longer does.

Earlier whenever a new invitation is created a event was sent
to only admin users. So, if invites by a non-admins user are changed
the invite panel does not live update.
This commit makes changes to also send event to non-admin
user if invites by them are changed.
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`.
Creates process for demo organization owners to add an email address
and password to their account.
Uses the same flow as changing an email (via user settings) at the
beginning, but then sends a different email template to the user
for the email confirmation process.
We also encourage users to set their full name field in the modal for
adding an email in a demo organization. We disable the submit button
on the form if either input is empty, email or full name.
When the user clicks the 'confirm and set password' button in the
email sent to confirm the email address sent via the form, their
email is updated via confirm_email_change, but the user is redirected
to the reset password page for their account (instead of the page for
confirming an email change has happened).
Once the user successfully sets a password, then they will be
prompted to log in with their newly configured email and password.
To make creation of demo organizations feel lightweight for users,
we do not want to require an email address at sign-up. Instead an
empty string will used for the new realm owner's email. Currently
implements that for new demo organizations in the development
environment.
Because the user's email address does not exist, we don't enqueue
any of the welcome emails upon account/realm creation, and we
don't create/send new login emails.
This is a part of #19523.

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.
Users who used to be subscribed to a private stream and have been
removed from it since retain the ability to edit messages/topics, and
delete messages that they used to have access to, if other relevant
organization permissions allow these actions. For example, a user may be
able to edit or delete their old messages they posted in such a private
stream. An administrator will be able to delete old messages (that they
had access to) from the private stream.
We fix this by fixing the logic in has_message_access (which lies at the
core of our message access checks - access_message() and
bulk_access_messages())
to not rely on only a UserMessage row for checking access but also
verify stream type and subscription status.
**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.
We want to make the callers be more explicit about the use of the
user group being accessed, so that the later implemented database lock
can be benefited from the visibility.
We do not want to access realm from "sender" field so that
we do not need to pass "sender__realm" argument to
select_related call when querying messages. We can instead
pass realm as argument to wildcard_mention_allowed.
We can directly get the realm object from Message object now
and there is no need to get the realm object from "sender"
field of Message object.
After this change, we would not need to fetch "sender__realm"
field using "select_related" and instead only passing "realm"
to select_related when querying Message objects would be enough.
This commit also updates a couple of cases to directly access
realm ID from message object and not message.sender. Although
we have fetched sender object already, so accessing realm_id
from message directly or from message.sender should not matter,
but we can be consistent to directly get realm from Message
object whenever possible.
We set stream_weekly_traffic field to "null" for Subscription
objects in zephyr mirror realm as we do not need stream traffic
data in zephyr mirror realm. This makes the subscription data
consistent with steams data.
This commit also udpates test to check never_subscribed data for
zephyr mirror realm.
Instead of having a "realm.is_zephyr_mirror_realm" check for every
get_streams_traffic call, this commit udpates get_streams_traffic to
accept realm as parameter and return "None" for zephyr mirror realm.
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.

This commit removes the private stream suscriptions of the bot if the
original owner is deactivated and we change the owner to the user who
is reactivating the bot. We unsusbcribe the bot from private streams
that the new owner is not subscribed to.
Fixes part of #21700.
We remove bot's subscriptions for private streams to which the
new owner is not subscribed and keep the ones to which the new
owner is subscribed on changing owner.
This commit also changes the code for sending subscription
remove events to use transaction.on_commit since we call
the function inside a transactopn in do_change_bot_owner and
this also requires some changes in tests in test_events.
Earlier, for topic wildcard mentions, the 'wildcard_mentioned'
flag was set for all the user-messages. (similar to stream wildcard
mention).
The flag should be set for the topic participants only.
The bug was introduced in 4c9d26c.
For topic wildcard mentions, the 'wildcard_mentioned' flag is set
for those user messages having 'user_profile_id' in
'topic_participant_user_ids', i.e. all topic participants.
Earlier, the flag was set if the 'user_profile_id' exists in
'all_topic_wildcard_mention_user_ids'.
'all_topic_wildcard_mention_user_ids' contains the ids of those
users who are topic participants and have enabled notifications
for '@topic' mentions.
The earlier approach was incorrect, as it would set the
'wildcard_mentioned' flag only for those topic participants
who have enabled the notifications for '@topic' mention instead
of setting the flag for all the topic participants.
The bug was introduced in 4c9d26c.
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`.

Update the docs to reflect the change in the above-mentioned trigger

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.
This commit adds stream_to_dict method which is same as
Stream.to_dict method as of now. This is a prep commit
to include stream traffic data in stream objects.
Previously, this code:
```python3
old_archived_attachments = ArchivedAttachment.objects.annotate(
has_other_messages=Exists(
Attachment.objects.filter(id=OuterRef("id"))
.exclude(messages=None)
.exclude(scheduled_messages=None)
)
).filter(messages=None, create_time__lt=delta_weeks_ago, has_other_messages=False)
```
...protected from removal any ArchivedAttachment objects where there
was an Attachment which had _both_ a message _and_ a scheduled
message, instead of _either_ a message _or_ a scheduled message.
Since files are removed from disk when the ArchivedAttachment rows are
deleted, this meant that if an upload was referenced in two messages,
and one was deleted, the file was permanently deleted when the
ArchivedMessage and ArchivedAttachment were cleaned up, despite being
still referenced in live Messages and Attachments.
Switch from `.exclude(messages=None).exclude(scheduled_messages=None)`
to `.exclude(messages=None, scheduled_messages=None)` which "OR"s
those conditions appropriately.
Pull the relevant test into its own file, and expand it significantly
to cover this, and other, corner cases.
Earlier the API endpoints related to user_group accepts and returns a
field `can_mention_group_id` which represents the ID

This commit renames this field to `can_mention_group`.

field `can_remove_subscribers_group_id` which represents the ID
of user_group whose members can remove subscribers from stream.
This commit renames this field to `can_remove_subscribers_group`.
Previously, the view function was responsible for doing a first pass of
the validations done for RealmPlayground. It is no longer true now. This
refactors do_add_realm_playground to check_add_realm_playground and make
it responsible for validating the playground fields and doing error
handling for the ValidationError raised.
Dropping support for url_prefix for RealmPlayground, the server now uses
url_template instead only for playground creation, retrieval and audit
logging upon removal.
This does the necessary handling so that url_template is expanded with
the extracted code.

As an intermediate step before we fully support url_template for realm

We used to access the complete objects for UserProfile foreign
keys like "bot_owner" and "default_sending_stream", where we only
needed ID of them.
This commit fixes some of such instances and now we directly get
the id using "bot_owner_id" and "default_sending_stream_id" so
that we can avoid the unnecessary complexity of accessing the
complete object.
We do not use any related fields for the UserProfile objects
fetched by get_active_users, so we can simply remove the
select_related call.
The user object from get_active_users was used to get realm
but since get_active_users called from a realm object we can
directly use that realm object. This change also leads to
some changes in the cache code where we now pass the realm
to the function instead of selecting it from UserProfile object.
Translators benefit from the extra information in the field names, and
need the reordering freedom that isn’t available with multiple
positional fields.

Fundamentally, we should take a write lock on the message, check its
validity for a change, and then make and commit that change.
Previously, `check_update_message` did not operate in a transaction,
but `do_update_message` did -- which led to the ordering:
- `check_update_message` reads Message, not in a transaction
- `check_update_message` verifies properties of the Message
- `do_update_message` starts a transaction
- `do_update_message` takes a read lock on UserMessage
- `do_update_message` writes on UserMessage
- `do_update_message` writes Message
- `do_update_message` commits
This leads to race conditions, where the `check_update_message` may
have verified based on stale data, and `do_update_message` may
improperly overwrite it; as well as deadlocks, where
other (properly-written) codepaths take a write lock on Message
_before_ updating UserMessage, and thus deadlock with
`do_update_message`.
Change `check_update_message` to open a transaction, and take the
write lock when first accessing the Message row. We update the
comment above `do_update_message` to clarify this expectation.
The new ordering is thus:
- `check_update_message` starts a transaction
- `check_update_message` takes a write lock on Message
- `check_update_message` verifies properties of the Message
- `do_update_message` writes on UserMessage
- `do_update_message` writes Message
- `check_update_message` commits
This commit completes the notifications part of the @topic
wildcard mention feature.
Notifications are sent to the topic participants for the
@topic wildcard mention.
The previous function was poorly named, asked for a
Realm object when realm_id sufficed, and returned a
tuple of strings that had different semantics.
I also avoid calling it duplicate times in a couple
places, although it was probably rarely the case that
both invocations actually happened if upstream
validations were working.
Note that there is a TypedDict called EmojiInfo, so I
chose EmojiData here. Perhaps a better name would be
TinyEmojiData or something.
I also simplify the reaction tests with a verify
helper.
The active realm emoji are just a subset of all your
realm emoji, so just use a single cache entry per
realm.
Cache misses should be very infrequent per realm.
If a realm has lots of deactivated realm emoji, then
there's a minor expense to deserialize them, but that
is gonna be dwarfed by all the other more expensive
operations in message-send.
I also renamed the two related functions. I erred on
the side of using somewhat verbose names, as we don't
want folks to confuse the two use cases. Fortunately
there are somewhat natural affordances to use one or
the other, and mypy helps too.
Finally, I use realm_id instead of realm in places
where we don't need the full Realm object.
We did not send the stream creation events when subscribing
guests to public streams while we do send them when subscribing
non-admin users to private streams.
This commit adds code to send the stream creation events when
subscribing guests to public streams, so the clients can know
that the stream exists and fixes the bug where client tries
to process a subscription add event for a stream which it does
not know about.
This commit adds the 'topic_wildcard_mention_user_ids' and
'topic_wildcard_mention_in_followed_topic_user_ids'
attributes to the 'RecipientInfoResult' dataclass.
Only topic participants are notified of @topic mentions.
Topic participants are anyone who sent a message to a topic
or reacted to a message on the topic.
'topic_wildcard_mention_in_followed_topic_user_ids' stores the
ids of the topic participants who follow the topic and have
enabled the wildcard mention notifications for followed topics.
'topic_wildcard_mention_user_ids' stores the ids of the topic
participants for whom 'user_allows_notifications_in_StreamTopic'
with setting 'wildcard_mentions_notify' returns True.
Previously this limit was 1 week, which was fine for busy
organizations, but for organizations that send a few messages a week,
or have occasional bursts of activity but the last one was a few weeks
ago, this should give a significantly better new user experience.
There are still caps like 1000 messages total and 20
unread, but we're a bit more flexible about time.
The initial followup_day1 email confirms that the new user account
has been successfully created and should be sent to the user
independently of an organization's setting for send_welcome_emails.
Here we separate out the followup_day1 email into a separate function
from enqueue_welcome_emails and create a helper function for setting
the shared welcome email sender information.
The followup_day1 email is still a scheduled email so that the initial
account creation and log-in process for the user remains unchanged.
Fixes#25268.
We remove the cache functionality for the
get_realm_stream function, and we also change it to
return a thin Stream object (instead of calling
select_related with no arguments).
The main goal here is to remove code complexity, as we
have been prone to at least one caching validation bug
related to how Realm and UserGroup interact. That
particular bug was more theoretical than practical in
terms of its impact, to be clear.
Even if we were to be perfectly disciplined about only
caching thin stream objects and always making sure to
delete cache entries when stream data changed, we would
still be prone to ugly situations like having
transactions get rolled back before we delete the cache
entry. The do_deactivate_stream is a perfect example of
where we have to consider the best time to unset the
cache. If you unset it too early, then you are prone to
races where somebody else churns the cache right before
you update the database. If you set it too late, then
you can have an invalid entry after a rollback or
deadlock situation. If you just eliminate the cache as
a moving part, that whole debate is moot.
As the lack of test changes here indicates, we rarely
fetch streams by name any more in critical sections of
our code.
The one place where we fetch by name is in loading the
home page, but that is **only** when you specify a
stream name. And, of course, that only causes about an
extra millisecond of time.
We want to avoid Django going back to the database to
get a realm object that the caller already has.
It's actually currently the case that we often
pre-fetch realm objects when we get stream objects
using get_stream (using a call to select_related() with
no arguments), but that is an expensive operation that
we want to avoid going forward.
This commit prepares us to just fetch slim objects.
This add audit log entries when any group based setting of a user group
is updated. We store both the old and new values in extra_data, along
with the name of that setting. Entries populated during user group creation
are hardcoded to track "can_mention_group".
Potentially we can adjust "set_defaults_for_group_settings" so that it
populates realm audit logs with it, but that is out of scope for this change.
We use an atomic transaction so that the audit logs are committed
together with the updates.

This is mostly the same as tracking subgroup changes, except that now
modified_user_group is the subgroup.

It's worth noting that instead of adding another field to the
RealmAuditLog model, we store the modified subgroup ids in extra_data as
a JSON encoded dict with the key "subgroup_ids". We don't create audit
log entries for supergroup changes at this point.

Various cleanups:
* clean up comments
* improve names for constants and variables
* express first ORM query as a single statement
* use set differences to simplify logic
* avoid all the reversing churn
* avoid early-exit idiom since this function is so small
Note that it's plausible that we should just combine the two
queries and let the database exclude the already-used ids,
but that felt a little risky for now. As I mentioned on
Zulip, I think the one-week window has dubious value, but
I am biased by having wasted time chasing down a test
flake related to the time window.
Basically, I eliminate the use of select_all() in a query
that still makes a single round trip. We have good test
enforcement that Django never needs to lazily fetch
objects off the Stream object. (It used to be common
to fetch stream.realm a while back, but we upgraded
bulk_add_subscription, in particular, a while back.)
We extract code from process_new_human_user with
no modifications.
This has all the best outcomes of extracting a function:
* better profile info
* easier to test for query counts (signup gets real noisy)
* simplifies a long, messy function
It has no real drawbacks, since the helper function doesn't need
to pass back any intermediate state to the parent for the rest
of what the parent does.
When you profile test_signup and test_invite, with a decent
sample size, the set_up_streams_for_new_human_user function
does about 20% of the work for process_new_human_user, which
is a lot considering that most tests don't create a ton of
pre-registered or default streams.
I created zerver/lib/default_streams.py, so that various
views and events.py don't have to awkwardly reach into
an "actions" file.
I copied over two functions verbatim from actions/default_streams.py:
get_default_streams_for_realm
streams_to_dicts_sorted
The latter only remains as an internal detail in the new library.
I also created two new helpers:
get_default_stream_ids_for_realm:
This is both faster and easier to use in all the places
where we only need to get a set of default stream ids.
get_default_streams_for_realm_as_dicts:
This just wraps the prior calls to
streams_to_dicts_sorted(get_default_streams_for_realm(...)),
and it doesn't yet address the slowness of the underlying
code.
All the "real" code should be functionally the same.
In a few tests I now use this wrapper instead of
calling get_default_streams_for_realm, just to get
slightly deeper coverage.
This prep commit replaces the 'wildcard' keyword in the codebase
with 'stream_wildcard' at some places for better readability, as
we plan to introduce 'topic_wildcards' as a part of the
'@topic mention' project.
Currently, 'wildcards = ["all", "everyone", "stream"]' which is an
alias to mention everyone in the stream, hence better renamed as
'stream_wildcards'.
Eventually, we will have:
'stream_wildcard' as an alias to mention everyone in the stream.
'topic_wildcard' as an alias to mention everyone in the topic.
'wildcard' refers to 'stream_wildcard' and 'topic_wildcard' as a whole.

django-stubs 4.2.1 gives transaction.on_commit a more accurate type
annotation, but this exposed that mypy can’t handle the lambda default
parameters that we use to recapture loop variables such as
for stream_id in public_stream_ids:
peer_user_ids = …
event = …
transaction.on_commit(
lambda event=event, peer_user_ids=peer_user_ids: send_event(
realm, event, peer_user_ids
)
)
https://github.com/python/mypy/issues/15459
A workaround that mypy accepts is
transaction.on_commit(
(
lambda event, peer_user_ids: lambda: send_event(
realm, event, peer_user_ids
)
)(event, peer_user_ids)
)
But that’s kind of ugly and potentially error-prone, so let’s make a
helper function for this very common pattern.
send_event_on_commit(realm, event, peer_user_ids)

This commit makes it possible for users to control the wildcard

via a global notification setting.
There is no support for configuring this setting
through the UI yet.

This commit makes it possible for users to control
the email notifications for messages sent to followed topics
via a global notification setting.
Although there is no support for configuring this setting
through the UI yet.
Add five new fields to the UserBaseSettings class for
the "followed topic notifications" feature, similar to
stream notifications. But this commit consists only of
the implementation of email notifications.
Note that we use the DjangoJSONEncoder so that we have builtin support
for parsing Decimal and datetime.
During this intermediate state, the migration that creates
extra_data_json field has been run. We prepare for running the backfilling
migration that populates extra_data_json from extra_data.
This change implements double-write, which is important to keep the
state of extra data consistent. For most extra_data usage, this is
handled by the overriden `save` method on `AbstractRealmAuditLog`, where
we either generates extra_data_json using orjson.loads or
ast.literal_eval.
While backfilling ensures that old realm audit log entries have
extra_data_json populated, double-write ensures that any new entries
generated will also have extra_data_json set. So that we can then safely
rename extra_data_json to extra_data while ensuring the non-nullable
invariant.
For completeness, we additionally set RealmAuditLog.NEW_VALUE for
the USER_FULL_NAME_CHANGED event. This cannot be handled with the
overridden `save`.
This addresses: https://github.com/zulip/zulip/pull/23116#discussion_r1040277795
Note that extra_data_json at this point is not used yet. So the test
cases do not need to switch to testing extra_data_json. This is later
done after we rename extra_data_json to extra_data.
Double-write for the remote server audit logs is special, because we only
get the dumped bytes from an external source. Luckily, none of the
payload carries extra_data that is not generated using orjson.dumps for
audit logs of event types in SYNC_BILLING_EVENTS. This can be verified
by looking at:
`git grep -A 6 -E "event_type=.*(USER_CREATED|USER_ACTIVATED|USER_DEACTIVATED|USER_REACTIVATED|USER_ROLE_CHANGED|REALM_DEACTIVATED|REALM_REACTIVATED)"`
Therefore, we just need to populate extra_data_json doing an
orjson.loads call after a None-check.

Part of splitting creating and editing scheduled messages.
Should be merged with final commit in series. Breaks tests.
Splits out editing an existing scheduled message into a new
view function and updated `edit_scheduled_message` function.
Part of splitting creating and editing scheduled messages.
Should be merged with final commit in series. Breaks tests.
Removes `scheduled_message_id` parameter from the create scheduled
message path.
As of commit 38f6807af1, we accept only stream and user IDs for
the recipient information for scheduled messages, which means we
can simplify the type for `message_to` in `check_schedule_message`.
We now allow users to change email address visibility setting
on the "Terms of service" page during first login. This page is
not shown for users creating account using normal registration
process, but is useful for imported users and users created
through API, LDAP, SCIM and management commands.
In the case of a user editing a scheduled message that the server
had failed to send at the scheduled time due to an error, we want
to update the `failed` and `failure_message` fields as the intent
is for the server to retry to send the scheduled message based on
the updated information provided by the user.
In the case that there is an error when sending a scheduled message,
we now send a message from the notification bot to the user who
scheduled the message about the failure/error.
The notification message is not sent if the error when sending the
scheduled message was due to the realm or sender being deactivated.
The code for updating visibility policy values on moving messages
had two bugs.
- There was a typo in elif condition where "user_profile" was being
used instead of "user_profile_with_policy".
This commit fixes the typo.
- It was assumed that there would be no UserTopic rows for target
topic if the target topic didn't exist. But there can be such case
where some messages were sent to that topic and the user muted
the topic. But then the messages in that topic was deleted. In
such case there can be UserTopic rows for a stream-topic pair
that does not exist.
This commit fixes the code to handle such case as well and set
the visibility policy of new topic to what was set for the original
topic. This change simplifies the condition to just check whether
new_visibility_policy is equal to target_topic_visibility_policy
and skip if so, and update the visibility policy otherwise.
Due to this change, we now do not try to mute the already muted
topic if the topic is moved to a topic which didn't exist
previously and thus we modify the existing test to not expect
any INFO logs.
We do not pass "email_address_visibility" to do_create_realm
anymore. It was passed before to set the setting for realms in
development database, but it has been changed since we changed
email_address_visibility to be a user-level setting instead
of realm-level setting since now it is set on RealmUserDefault
table.
We do not add user to the default streams if the streams list passed
while sending the invite (both email and multi-use) was empty since
invite explicitly selected to not subscribe the user to default
streams.
Previously, it seemed possible for the scheduled messages API to try
to send infinite copies of a message if we had the very poor luck of a
persistent failure happening after a message was sent.
The failure_message field supports being able to display what happened
in the scheduled messages modal, though that's not exposed to the API
yet.
For scheduled stream messages, we already limited the `to`
parameter to be the stream ID, but here we return a JsonableError
in the case of a ValueError when the passed value is not an integer.
For scheduled direct messages, we limit the list for the `to`
parameter to be user IDs. Previously, we accepted emails like
we do when sending messages.
