Having a more precise type annotation helps with ensuring the migration

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.

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.

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.
Doing so causes the "username resolved this topic" or "this topic was
moved by username" notifications to be attributed to a random user who
had a visibility policy on the topic.
Fixes#25414.
We add Attachment.scheduled_messages relation to track ScheduledMessages
which reference the attachment.
The import bits can be done after merging this, by updating #25345.
Because education organizations and users have slightly specialized
use cases, we update the Welcome Bot message content sent to new
users and new organization owners for these types of organizations
to link to help center articles/guides geared toward these users
and organizations.
Also, updates the demo organization warning to only go to the new
demo organization owner because the 30 day deletion text is only
definitely accurate when the organization is created.
Fixes#21694.
In commit fc58c35c0, we added a check in various emails for the
settings.CORPORATE_ENABLED value, but that context is only always
included for views/templates with a request.
Here we add that to common_context, which is often used when there
is not a request (like with emails). And we manually add it to the
email context in various cases when there is not a user account to
call with common_context: new user invitations, registration emails,
and realm reactivation emails.
This was previously called delete_event_notify_user_ids, which seemed
to narrow its purpose in a way that was confusing given that it's also
used for other calculations.
Further, calculate it as soon as we know it, not when we're first
going to use it.
This also removes the error in one of these functions that was using a
different constant instead of
PRESENCE_LEGACY_EVENT_OFFSET_FOR_ACTIVITY_SECONDS.
This implements the core of the rewrite described in:
For the backend data model for UserPresence to one that supports much
more efficient queries and is more correct around handling of multiple
clients. The main loss of functionality is that we no longer track
which Client sent presence data (so we will no longer be able to say
using UserPresence "the user was last online on their desktop 15
minutes ago, but was online with their phone 3 minutes ago"). If we
consider that information important for the occasional investigation
query, we have can construct that answer data via UserActivity
already. It's not worth making Presence much more expensive/complex
to support it.
For slim_presence clients, this sends the same data format we sent
before, albeit with less complexity involved in constructing it. Note
that we at present will always send both last_active_time and
last_connected_time; we may revisit that in the future.
This commit doesn't include the finalizing migration, which drops the
UserPresenceOld table.
The way to deploy is to start the backfill migration with the server
down and then start the server *without* the user_presence queue worker,
to let the migration finish without having new data interfering with it.
Once the migration is done, the queue worker can be started, leading to
the presence data catching up to the current state as the queue worker
goes over the queued up events and updating the UserPresence table.

This swaps out url_format_string from all of our APIs and replaces it
with url_template. Note that the documentation changes in the following
commits will be squashed with this commit.
We change the "url_format" key to "url_template" for the
realm_linkifiers events in event_schema, along with updating
LinkifierDict. "url_template" is the name chosen to normalize
mixed usages of "url_format_string" and "url_format" throughout
the backend.
The markdown processor is updated to stop handling the format string
interpolation and delegate the task template expansion to the uri_template
library instead.
This change affects many test cases. We mostly just replace "%(name)s"
with "{name}", "url_format_string" with "url_template" to make sure that
they still pass. There are some test cases dedicated for testing "%"
escaping, which aren't relevant anymore and are subject to removal.
But for now we keep most of them as-is, and make sure that "%" is always
escaped since we do not use it for variable substitution any more.
Since url_format_string is not populated anymore, a migration is created
to remove this field entirely, and make url_template non-nullable since
we will always populate it. Note that it is possible to have
url_template being null after migration 0422 and before 0424, but
in practice, url_template will not be None after backfilling and the
backend now is always setting url_template.
With the removal of url_format_string, RealmFilter model will now be cleaned
with URL template checks, and the old checks for escapes are removed.
We also modified RealmFilter.clean to skip the validation when the
url_template is invalid. This avoids raising mulitple ValidationError's
when calling full_clean on a linkifier. But we might eventually want to
have a more centric approach to data validation instead of having
the same validation in both the clean method and the validator.

This commit updates the logic for migrating user_topic rows
during the move-messages operation when the target topic
already has messages.
Previously, the target_topic's visibility_policy was simply
set to the original_topic's visibility_policy,
and the original_topic's visibility_policy was set to INHERIT.
This commit updates the move-messages code path to determine
the new visibility_policy depending on the visibility policies
of the original and target topics.
The target_topic's visibility_policy is then updated.
The number of db queries has increased by two:
One query corresponds to determining if 'target_topic_has_messages'.
Another query corresponds to 'get_users_with_user_topic_visibility_policy'
to determine 'target_topic_user_profile_to_visibility_policy'.
This commit refactors the move user_topic records
code block in 'do_update_message', resulting in
clean code.
We directly iterate over the dictionary items
instead of looping over the keys and fetching
values if the key exists.
Refactors instances of `message_type_name` and `message_type`
that are referring to API message type value ("stream" or
"private") to use `recipient_type_name` instead.
Prep commit for adding "direct" as a value for endpoints with a
`type` parameter to indicate whether the message is a stream or
direct message.
So far, we've used the BitField .authentication_methods on Realm
for tracking which backends are enabled for an organization. This
however made it a pain to add new backends (requiring altering the
column and a migration - particularly troublesome if someone wanted to
create their own custom auth backend for their server).
Instead this will be tracked through the existence of the appropriate
rows in the RealmAuthenticationMethods table.
If the ID of the scheduled message is passed by the client, we
edit the existing scheduled message instead of creating a new one.
However, this will soon be moved into its own API endpoint.
We previously allowed moving messages that have passed the time limit
using "change_all" value for "propagate_mode" parameter. This commit
changes the behavior to not allow moving messages (both stream and
topic edit) that have passed the time limit for non-admin and
non-moderator users.
Previously, editing topic of "(no topic)" messages was allowed
irrespective of time limit or the "edit_topic_policy" setting.
Since we are working in the direction of having "no topic" messages
feel reasonable, this commit changes the code to not consider them
as a special case and topic editing restrictions apply to them as
well now like all other messages.
We still highlight the topic edit icon in recipient bar without
hovering for "no topic" messages, but it is only shown when user
has permission to edit topics.
Improve the Notification Bot by adding a hyperlink to the new location
of a moved single message. The link will make it easier for users to
find the message in its new context.
Fixes#24604.
This commit updates the move-topic codepath to perform
bulk database operations on the UserTopic record using
user_profiles for each visibility_policy instead of
previously looping over each user_profile one by one.
This commit refactors 'set_user_topic_visibility_policy_in_database'
to perform bulk database operations and the related changes.
There is an increase in database query count because requests
to delete user_topic rows now take two queries instead of one.
This is required for logging the info for a request to delete
a non-existent user_topic row while performing bulk operations
at the same time.
The overall query count will be lower while performing
bulk operations (multiple user_profiles instead of one).
This commit updates the 'do_update_message' codepath to
update the UserTopic records regardless of visibility policy
during the "move-topic" operation.
This is required before offering new visibility policies
in the UI.
Previously, UserTopic records were moved or deleted only
for objects with a MUTED visibility policy.
Fixes: #24574
Since we have updated the registration code to use
PreregistrationRealm objects for realm creation in
previous commits, some of the code has become
redundant and this commit removes it.
We remove the following code -
- The modification to PreregistrationUser objects in
process_new_human_user can now be done unconditionally
because prereg_user is passed only during user creation
and not realm creation. And we anyway do not expect
any PreregistrationUser objects inside the realm
during the creation.
- There is no need of "realm_creation" parameter in
create_preregistration_user function, since we now
use create_preregistration_realm during realm creation.
Fixes part of #24307.
Previously, when a user moves a message to another topic, the Notification
bot will post a message saying "This topic was moved here from..." This is
confusing when the topic already contains messages. The changes aims to make
the messages more clear by changing the logic for the Notification bot. When
there is already messages in the topic, the bot will post "A message was
moved here from..." or "N messages were moved here from...". The bot will
post "This topic was moved here from (somewhere) by (someone)." when the
topic is empty.

"check_add_user_group" is a safer helper function than

Note that the populate_db command still uses "create_user_group"
because we do not need to enqueue events at that point.

We previously created RealmAuditLog entries for user notification
settings only. This commit changes the code to create entries for
all user settings. We cannot backfill the entries since we don't
have the data to do that.
When a new realm is created, a notification message is sent to
the realm configured as the settings.SYSTEM_BOT_REALM if there
is a "signups" stream that exists in that realm. This is used
for Zulip Cloud, but is an undocumented feature.
The topic of the message has been the subdomain of the new realm,
and the message content has been "Signups enabled" translated
into the default language of the new realm.
In order to make these messages more explicitly for Zulip Cloud,
the settings.CORPORATE_ENABLED is checked before sending these
messages.
To make these messages more useful, the topic for these
notifications is changed to be "new organizations". The content
of these messages is updated to have the new realm name (with a
link to the admin realm's activity support page for the realm),
subdomain (with a link to the realm), and organization type.
The RealmCount statistics will be empty if the realm was created since
the last daily aggregation. In cases where the daily stats have no
rows, it is likely fast enough to do the real count in the messages
table. This stops unduly penalizing folks who have actually sent
messages, and are just inviting people within the first day.
This commit updates 'set_user_topic_visibility_policy_in_database'
to not raise an error when deleting a UserTopic row and the user
doesn't have a visibility_policy for the topic yet, or when setting
the visibility_policy to its current value.
Also, it includes the changes to not send unnecessary events
in such cases.
Removes the notification message that was sent if a stream named
"signups" exists in the `settings.SYSTEM_BOT_REALM`. This was a
undocumented feature that would send a notification message when
a new user registered with a Zulip organization that was hosted
by an admin realm like Zulip Cloud.
This removes two database queries when a new user is created: one
to get the system bot realm and the other to get the notification
bot in said realm.
Note that there are still notification messages sent when a new
organization is registered with the admin realm if the "signups"
stream exists.
This commit refactors 'do_set_user_topic_visibility_policy'
to remove the if/else block and just have a single call to
'set_user_topic_visibility_policy_in_database'.
The branching out behaviour based on the user_topic
visibility_policy is reduced to one place, i.e.,
'set_user_topic_visibility_policy_in_database'.
This commit refactors the notify_created_user function to
call format_user_row twice with different parameters instead
of modifying the person object returned by format_user_row.
This change makes the code somewhat more easy to understand
than it was before.
dc1eeef30a made the column nullable, with the meaning for null of
"use the current `settings.INVITES_DEFAULT_REALM_DAILY_MAX`."
However, 8a95526ced switched to calling `do_change_plan_type` during
realm creation, which sets `realm.max_invites` based on the plan type,
thus ensuring that no new realms have their `_max_invites` set to
null.
Check `max_invites` instead of `_max_invites`. This requires test
adjustments for the fact that `apply_invite_realm_heuristics` is now
run.
This commit adds 'visibility_policy' as a
parameter to user_allows_notifications_in_StreamTopic
function.
This adds logic inside the user_allows_notifications_in_StreamTopic
function, to not return False when a stream is muted
but the topic is UNMUTED.
Adds a method `user_id_to_visibility_policy_dict`
to 'StreamTopicTarget' class to fetch
(user_id => visibility_policy) in single db query.

This commit replaces 'remove_topic_mute' with
'set_user_topic_visibility_policy_in_database' and
updates it to delete UserTopic row with any configured
visibility_policy and not just muting.
In order to support different types of topic visibility policies,
this renames 'add_topic_mute' to
'set_user_topic_visibility_policy_in_database'
and refactors it to accept a parameter 'visibility_policy'.
Create a corresponding UserTopic row for any visibility policy,
not just muting topics.
When a UserTopic row for (user_profile, stream, topic, recipient_id)
exists already, it updates the row with the new visibility_policy.
In the event of a duplicate request, raises a JsonableError.
i.e., new_visibility_policy == existing_visibility_policy.
There is an increase in the database query count in the message-edit
code path.
Reason:
Earlier, 'add_topic_mute' used 'bulk_create' which either
creates or raises IntegrityError -- 1 query.
Now, 'set_user_topic_visibility_policy' uses get_or_create
-- 2 queries in the case of creating new row.
We can't use the previous approach, because now we have to
handle the case of updating the visibility_policy too.
Also, using bulk_* for a single row is not the correct way.

Replaces 'do_unmute_topic' with 'do_set_user_topic_visibility_policy'
and associated minor changes.
This change is made to align with the plan to use a single function
'do_set_user_topic_visibility_policy' to manage
user_topic - visibility_policy changes and corresponding event
generation.
This commit is a step in the direction of having a common
function to handle visibility_policy changes and event
generation instead of separate functions for each
visibility policy.
In order to support different types of topic visibility policies,
this renames 'do_topic_mute' to 'do_set_user_topic_visibility_policy'
and refactors it to accept a parameter 'visibility_policy'.
This commit adds backend code to set email_address_visibility when
registering a new user. The realm-level default and the value of
source profile gets overridden by the value user selected during
signup.
In the case where a stream existed but had no subscribers, the error
message used to send to the owner always used `stream_name`, which
may have been None.
Switch to using `stream.name` rather than `stream_name` for this case.
We add stream_permission_group_settings object which is
similar to property_types framework used for realm settings.
This commit also adds GroupPermissionSetting dataclass for
defining settings inside stream_permission_group_settings.
We add "do_change_stream_group_based_setting" function which
is called in loop to update all the group-based stream settings
and it is now used to update 'can_remove_subscribers_group'
setting instead of "do_change_can_remove_subscribers_group".
We also change the variable name for event_type field of
RealmAuditLog objects to STREAM_GROUP_BASED_SETTING_CHANGED
since this will be used for all group-based stream settings.
'property' field is also added to extra_data field to identify
the setting for which RealmAuditLog object was created.
We will add a migration in further commits which will add the
property field to existing RealmAuditLog objects created for
changing can_remove_subscribers_group setting.
This old 300s value was meaningfully used in 2 places:
1. In the do_change_user_settings presence_enabled codepath when turning
a user invisible. It doesn't matter there, 140s is just since the
point is to make clients see this user as offline. And 140s is the
threshold used by clients (see the presence.js constant).
2. For calculating whether to set "offline" "status" in
result["presence"]["aggregated"] in get_presence_backend. It's fine
for this to become 140s, since clients shouldn't be looking at the
status value anymore anyway and just do their calculation based on
the timestamps.
Removes the initial check in `_internal_prep_message` of the length
of the message content because the `check_message` in the try block
will call `normalize_body` on the message content string, which
does a more robust check of the message content (empty string, null
bytes, length). If the message content length exceeds the value of
`settings.MAX_MESSAGE_LENGTH`, then it is truncated based on that
value. Updates associated backend test for these changes.
The removed length check would truncate the message content with a
hard coded value instead of using the value for
`settings.MAX_MESSAGE_LENGTH`.
Also, removes an extraneous comment about removing null bytes. If
there are null bytes in the message content, then `normalize_body`
will raise an error.
Note that the previous check had intentionally reduced any message over
the 10000 character limit to 3900 characters, with the code in
question dating to 2012's 100df7e349.
The 3900 character truncating rule was implemented for incoming emails
with the email gateway, and predated other features to help with
overly long messages (better stripping of email footers via Talon,
introduced in f1f48f305e, and
condensing, introduced in c92d664b44).
While we could preserve that logic if desired, it likely is no longer
a necessary or useful variation from our usual truncation rules.
This reverts commit 851d68e0fc.
That commit widened how long the transaction is open, which made it
much more likely that after the user was created in the transaction,
and the memcached caches were flushed, some other request will fill
the `get_realm_user_dicts` cache with data which did not include the
new user (because it had not been committed yet).
If a user creation request lost this race, the user would, upon first
request to `/`, get a blank page and a Javascript error:
Unknown user_id in get_by_user_id: 12345
...where 12345 was their own user-id. This error would persist until
the cache expired (in 7 days) or something else expunged it.
Reverting this does not prevent the race, as the post_save hook's call
to flush_user_profile is still in a transaction (and has been since
168f241ff0), and thus leaves the potential race window open.
However, it much shortens the potential window of opportunity, and is
a reasonable short-term stopgap.
This will allow us to re-use this logic later, when we add support for
re-checking notification settings just before sending email/push
notifications to the user.
Also, since this is essentially part of the notifiability logic,
this better belongs to `notification_data.py` and this change will
hopefully reduce the reading complexity of the message-send codepath.
This commits update the code to use user-level email_address_visibility
setting instead of realm-level to set or update the value of UserProfile.email
field and to send the emails to clients.
Major changes are -
- UserProfile.email field is set while creating the user according to
RealmUserDefault.email_address_visbility.
- UserProfile.email field is updated according to change in the setting.
- 'email_address_visibility' is added to person objects in user add event
and in avatar change event.
- client_gravatar can be different for different users when computing
avatar_url for messages and user objects since email available to clients
is dependent on user-level setting.
- For bots, email_address_visibility is set to EVERYONE while creating
them irrespective of realm-default value.
- Test changes are basically setting user-level setting instead of realm
setting and modifying the checks accordingly.
Previously, user objects contained delivery_email field
only when user had access to real email. Also, delivery_email
was not present if visibility setting is set to "everyone"
as email field was itself set to real email.
This commit changes the code to pass "delivery_email" field
always in the user objects with its value being "None" if
user does not have access to real email and real email otherwise.
The "delivery_email" field value is None for logged-out users.
For bots, the "delivery_email" is always set to real email
irrespective of email_address_visibility setting.
Also, since user has access to real email if visibility is set
to "everyone", "delivery_email" field is passed in that case
too.
There is no change in email field and it is same as before.
This commit also adds code to send event to update delivery_email
field when email_address_visibility setting changes to all the
users whose access to emails changes and also changes the code to
send event on changing delivery_email to users who have access
to email.
This commit adds time restriction on moving messages between streams
using the move_messages_between_streams_limit_seconds setting in the
backend. There is no time limit for admins and moderators.
We now use the newly added move_messages_within_stream_limit_seconds
setting to check for how long the user can edit the topic replacing
the previously used 3-day limit. As it was previously, there is no
time limit for admins and moderators.
This commit renames parse_message_content_edit_or_delete_limit
to parse_message_time_limit_setting and also renames
MESSAGE_CONTENT_EDIT_OR_DELETE_LIMIT_SPECIAL_VALUES_MAP to
MESSAGE_TIME_LIMIT_SETTING_SPECIAL_VALUES_MAP.
We do this change since this function and object will also be
used for message move limit and it makes sense to have a more
generic name.
This commit extracts a function to parse message time limit type settings
and to set it if the new setting value is None.
This function is currently used for message_content_edit_limit_seconds and
message_content_delete_limit_seconds settings and will be used for
message_move_limit_seconds setting to be added in further commits.
When 'resolve|unresolve' and 'move stream' actions occurs in
the same api call, 'This topic was marked as resolved|unresolved'
notification is not sent.
Both 'topic moved' and 'topic resolved' notification should be generated.
This commit updates the logic of when and where to send
'topic resolve|unresolve' notification. Unlike previous logic, notification
may be sent even in the case 'new_stream' is not None.
In general, 'topic resolved|unresolved' notification is sent to
'stream_being_edited'. In this particular case ('new_stream' is not None),
notification is sent to the 'new_stream' after check.
Test case is included.

We change the do_create_user function to use transaction.atomic
decorator instead of using with block. Due to this change, all
send_event calls are made inside transaction.on_commit.
Some other changes -
- Remove transaction.atomic decorator from send_inital_realm_messages
since it is now called inside a transaction.
- Made changes in tests which tests message events and notifications
to make sure on_commit callbacks are executed.
This commit changes the do_reactivate_user such that the complete function
is called inside an atomic transaction and events are called after the
transaction is commited using on_commit helper. This is a prep commit
for unsubscribing the bots of unaccessible private streams when reactivating
them.
A missed message email notification, where the message is the welcome
message sent by the welcome bot on account creation, get sent when
the user somehow not focuses the browser tab during account creation.
No missed message email or push notifications should be sent for the
messages generated by the welcome bot.
'internal_send_private_message' accepts a parameter
'disable_external_notifications' and is set to 'True' when the sender
is 'welcome bot'.
A check is introduced in `trivially_should_not_notify`, not to notify
if `disable_external_notifications` is true.
TestCases are updated to include the `disable_external_notifications`
check in the early (False) return patterns of `is_push_notifiable` and
`is_email_notifiable`.
One query reduced for both `test_create_user_with_multiple_streams`
and `test_register`.
Reason: When welcome bot sends message after user creation
`do_send_messages` calls `get_active_presence_idle_user_ids`,
`user_ids` in `get_active_presence_idle_user_ids` remains empty if
`disable_external_notifications` is true because `is_notifiable` returns
false.
`get_active_presence_idle_user_ids` calls `filter_presence_idle_user_ids`
and since the `user_ids` is empty, the query inside the function doesn't
get executed.
MissedMessageHookTest updated.

For alert words, we currently don't send email/push notifications --
only desktop notifications. Thus, we don't need to consider alert words
here, since desktop notifications do not utilize the presence status
calculated at this stage.
Tested manually that alert word desktop notifications work as expected.
When we implement email/push notifications for alert words (issues #5137
and #13127), we can add new fields like
`notifications_data.alert_word_email_notify`, similar to the existing
`notifications_data.wildcard_mention_email_notify`, which will allow us
to keep the alert word notifiability check inside the dataclass, similar
to how the mentions checks are done currently. So, even when that
feature is implemented, the code which this commit removes would be
unnecessary.
This commit renames "can_edit_topic_of_any_message" function
in models.py to "can_move_messages_to_another_topic" and
"user_can_edit_topic_of_any_message" function in settings_data.js
to "user_can_move_messages_to_another_topic".
This change is done since topic editing permission does not
depend on message sender now and messages are considered same
irrespective of whether the user who is editing the topic had sent
the message or not. This also makes the naming consistent with
what we use for the label of this setting in webapp and how we
describe this action in help documentation.
This commit changes the topic edit permssions to not depend whether the user
editing the message had sent the message or it was sent by someone else.
We only do backend changes in this commit and frontend changes will be done
in further commits.
Previously, we always allowed topic edits when the user themseleves had
sent the message not considering the edit_topic_policy and the 3-day time
limit. But now we consider all messages as same and editing is allowed only
according to edit_topic_policy setting and the time limit of 3 days in
addition for users who are not admins or moderators.
We change the topic and stream edit permssions to not depend on
allow_message_editing setting in the API and are allowed even
if allow_message_editing is set to False based on other settings
like edit_topic_policy and can_move_message_between_streams.
Fixes a part of #21739.
This solves the problem that resolving a topic with a long name (>60
characters) will cause the topic name to be truncated, and thus the edit
message code path thinks that the topic is being moved in addition to
being resolved.
We store the pre-truncation topic and use it to check against the
original topic when determining whether a topic is being moved while
getting (un)resovled or not.

We intended to send both the "topic was resolved" and the "topic was
moved here" notification when resolving and moving a topic at the same
time in #22312.
The previous implementation did not work as expected and it was only
sending the "topic was moved here" notification.
This removes the check for old_topic and new_topic that have
RESOLVED_TOPIC_PREFIX stripped in maybe_send_resolve_notifications, so
that the notification will be sent regardless if the topic name without
the prefix stays the same or not.
Note that weird topic handling ("✔ ✔✔ some topic") in the comments
was added in e231a03eff is unaffected. In case of confusion, the lstrip
check is not essential to detecting topic being unresolved/resolved.
As we mainly have that handled in the latter part of the helper.

This is a follow-up to d201229df8.
do_get_invites_controlled_by_user queries for Confirmations when finding
multiuse invites controlled by a user. This means that a revoked
multiuse invite cannot really be fetched here, because
do_revoke_multi_use_invite deletes the Confirmation object when revoking
the invitations. However, having a defensive assert here should be
useful to make this doesn't secretly break in the future if the query
used changes or if there are unexpected revoked multiuse invites with an
existing Confirmations for any (buggy) reason.
This allows us to revoke MultiUseInvites by changing their .status
instead of deleting them (which has been deleting the helpful tracking
information on PreregistrationUsers about which MultiUseInvite they came
from).
We do not create historical UserMessage rows, for messages that didn't
have one, while marking messages as read and simply ignore those messages.
We do so because there is no user of creating UserMessage rows and it just
wastes storage.
Note that we still allow to mark messages from unsubscribed streams as
read but only those which have UserMessage rows for them to handle the
case when the unread messages were not marked as read while unsubscribing
from the stream due to some race condition. In such cases, messages
will not be included in the unread count shown in "All messages" menu
(and stream is anyways not present in the left sidebar), but the message
border on the left is green if viewing the stream after unsusbcribing it.
So, to avoid the confusion for users, the messages will be marked as read
when user scrolls down.
Zulip's unread messages design has an invariant that all unread stream
messages must be in streams the user is subscribed to. For example, We
do not include the unread messages from unsubscribed streams in the
"unread_msgs" data structure in "/register" response and we mark all
unread messages as read when unsubscribing a user from a stream.
Previously, the mark as unread endpoint allowed violating that
invariant, allowing you to mark messages in any stream as unread.
Doing so caused the "message_details" data structures sent with
"update_message_flags" events to not contain messages from
unsubscribed streams, even though those messages were present in the
set of message IDs. These malformed events, in turn, caused exceptions
in the frontend's processing of such an event.
This change is paired with a separate UI change to not offer the "Mark
as unread" feature in such streams; with just this commit, that will
silently fail.
With some additions to the tests by tabbott.
This guarantees that the Realm is always non-None when we hit the
codepath is_static_or_current_realm_url via
do_change_stream_description, so that we can properly skip rewritting
some images.

I don't think this is used anywhere outside of tests, but we should have
this logic correct. If this function is used to send a message from a
user to a cross-realm bot, the message.realm should be the realm of the
user.
In the normal case, where a user send a message to a cross-realm bot
through the API is already handled correctly, this bug is unrelated.
Previously we did not send notification for topic-only edits.
Now, we add backend support for sending notification to topic-only
edits as well.
We would add support for this in webapp in further commits since
message edit UI will be updated as well. We just make sure that no
notifications are sent when editing topic using pencil icon in
message header.
We also change the API default for moving a topic to only notify the
new location, not the old one; this matches the current defaults in
the web UI.
Includes many tests.
We also update the puppeteer tests to test only content edit as
we are going to change the UI to not allow topic editing from
message edit UI. Also fixing the existing tests to pass while
doing topic edits is somewhat complex as notification message
is also sent to new topic by default.

Previously, we included all three message edit related settings
("allow_message_editing", "message_content_edit_limit_seconds" and
"edit_topic_policy") in the event data and api response irrespective
of which of these settings were changed. Now, we only include changed
settings and separate events are sent for each setting if more than
one of them is changed.
Note that the previous typed in event_schema.py for
`message_content_edit_limit_seconds` incorrectly did not allow `None`
as a value, which is used to encode no limit.

First step of making user status `away` updates a deprecated way to

Note that when user status `away` is updated, we now send 4 events:
user_status, user_settings, presence, and update_global_notifications.
Also, this means that these updates change the UserPresence.status
value, which impacts the test for importing and exporting user
information.
Part of transitioning from 'unavailable' user status feature to

Previously, an active production Zulip server would experience a class
of deadlocks caused by two or more concurrent bulk update operations
on the UserMessage table.
This is because UPDATE ... SET ... WHERE statements that execute in
parallel take row-level UPDATE locks as they get results; since the
query plans may result in getting rows in different orders between two
queries, this can result in deadlocks.
Some databases allow ORDER BY on their UPDATE ... WHERE statements;
PostgreSQL does not. In PostgreSQL, the answer is to do a sub-select
with an ORDER BY ... FOR UPDATE to ensure consistent ordering on row
locks.
We do this all code paths using bitand or bitor as part of bulk
editing message flags, which should ensure that these concurrent
operations obtain row level locks on the table in the same order.

This will have no real effect in most situations. However, a user
moves a topic to another stream while also adding/removing the
resolved-topic checkmark from the topic name, then the "This topic was

moved" notification rather than just after.
This is likely slightly less confusing to users, since the topic
having been moved from somewhere else is likely the most salient fact
to a reader.
We expect to change things to not send both notifications in an
upcoming commit.
This refactoring helps with #21712.
Our seat count calculation is different for guest user than normal users
(a number of initial guests are free, and additional marginal guests are
worth 1/5 of a seat) - so these checks we apply when a user is being
invited or signing up need to know whether it's a guest or non-guest
being added.
In Zulip 2.1.0, the `is_muted` stream subscription property was
added and replaced the `in_home_view` property. But the server has
still only been sending subscription update events with the
`in_home_view` property.
Updates `do_change_subscription_property` to send a subscription
update event for both `is_muted` and `in_home_view`, so that
clients can fully migrate away from using `in_home_view` allowing
us to eventually remove it completely.
This is a prep commit such that we can avoid duplicate code when we
unsubscribe bots for inaccessible private streams when changing owner
or reactivating them.
This commit changes the code to consider zero as an invalid value for
message_content_edit_time_limit_seconds. Now to represent the setting that
user can edit the message anytime, the setting value will be "None" in
database and "unlimited" will be passed to API from clients.
Adds an API endpoint for accessing read receipts for other users, as
well as a modal UI for displaying that information.
Enables the previously merged privacy settings UI for managing whether
a user makes read receipts data available to other users.
Documentation is pending, and we'll likely want to link to the
documentation with help_settings_link once it is complete.
Fixes#3618.

We now use MEMBERS_GROUP_NAME instead of writing
the actual group name at multiple places, so that we
can have all the group names coded at one place only.
We now use FULL_MEMBERS_GROUP_NAME instead of
writing the actual full members system group
name at multiple places, so that we can have
all the group names coded at one place only.
I found the previous model for computing what settings to use for
streams increasingly difficult to understand, which is generally a
recipe for future bugs.
Refactor to have a clear computation of what complete permissions
state the client is requesting, validate that state, and then pass
that state to the do_change_stream_permission.
We now allow changing access to history of the stream by only passing
"history_public_to_subscribers" parameter. Previously, "is_private"
parameter was also required to change history_public_to_subscribers
otherwise the request was silently ignored.
We also raise error when only history_public_to_subscribers parameter
is passed with value False without "is_private: True" for a public
or web-public stream since we do not allow public streams with
protected history.
This commit removes the unnecessary assertion statements in
do_change_stream_permission for case when "is_web_public" is
True, since we already check those cases in the view function
update_stream_backend and this is the only place from where
do_change_stream_permission is called.
We aim to remove other assertions also from there as mentioned
in the comment and instead check the values in caller itself.
We now send a new user_topic event while muting and unmuting topics.
fetch_initial_state_data now returns an additional user_topics array to
the client that will maintain the user-topic relationship data.
This will support any future addition of new features to modify the
relationship between a user-topic pair.
This commit adds the relevent backend code and schema for the new
event.
We separate the permission checks for content and topic edits
by changing the can_edit_topic_or_content to can_edit_topic
and use it only for checking topic edits and check content
edits separately in check_update_message itself. There is no
change in behavior as of this PR, there will be more changes
as per #21739.
This is a prep commit for #21739. The permission checks for
them are essentially separate except the one that message
sender is allowed to edit content and topic irresepctive of
edit_topic_policy setting, and this will too be changed in
future commit and so it will be better to have these checks
separate for readability.
We can also probably create a new function for checking content
edits but currently we only check the sender is same as the use
who is editing and it does not make sense to have a separate
function for just one check. We can do so in future in case we
do some more refactoring for #21739.
We pass the realm_emoji dict to notify_realm_emoji instead
of computing it in notify_realm_emoji itself, because its
caller functions will require the dict in further commits
for creating RealmAuditLog entries.
This commit also renames the legacy event variable to
legacy_event from event because same event is sent
twice if we keep only single variable and change its
value. This was happening because the event value was
changed when the first send_event was actually executed.
We pass the realm_linkfiers list to notify_linkifiers instead of
computing it in notify_linkifiers itself, because its caller
functions will require the list in further commits for creating
RealmAuditLog entries.
Since we not allow enabling public access on limited plan realms,
we set the enable_spectator_access setting to False when downgrading
to a limited plan. Setting is still shown in the UI but it is
disabled.
This commit adds code to send stream creation and peer add events
when stream is changed from private to public. These events are
only sent to users who are not susbcribed to the stream and are
not realm admins as subscribers and realm admins already have
the stream data. This will update the stream data with clients
and will remove the need to reload to view the modified stream.
Fixes#22194.
We should not monkey-patch message when unnecessary. Adding
`service_queue_events` to `SendMessageRequests` suits our need to type
safety here.

This reverts commit 40fcf5a633.
This commit triggers bug that we haven't fully tracked down, where web
app clients will continually send `update_message_flags` requests,
that then send out via the events system "0 messages were marked as
read" notices, eventually leading to a load spike.
The Tornado part can likely be fixed by checking if
updated_message_ids is empty, but we need to track down the frontend
bug as well.
Previously, automated stream messages for new user signups were not
being translated into the realm's default language for said messages.
Moves `override_language` context manager so that it wraps the
new user message content in `notify_new_user` and topic string in
`send_message_to_signup_notification_stream`.
Fixes#22510.
The dangling comment was not very helpful and unclear about the pieces
of code it was referring to.
We expand the part about linking the prereg_user to the created user,
while the part about "revoking other preregistration users" is
redundant, because the relevant code block lower down already has
comments on it with better explanations.
Closes#22274.
This assertion was added in 4b903c5dcd
where it may have made sense, because indeed when doing realm creation
there was always a PreregistrationUser (created because realms were
created via going to a generated realm creation link). With the addition
of the create_realm command that's no longer the case.
It would be unnatural to create a PreregistrationUser in the
realm_creation command, because there is no confirmation link for it to
be tied to - and it just doesn't make sense conceptually.
The intended, correct behavior added in
4b903c5dcd is still maintained - the code
lower down correctly handles the
(prereg_user is None and realm_creation) case.
The type safety of a TypeGuard is unchecked by mypy. While this
particular TypeGuard is safe given the current context, one could
imagine future changes that make it unsafe, so it’s preferable to
avoid unchecked constructs whenever possible.

django-stubs types the return type of query.values(...) as a TypedDict.
This makes Dict[str, Any] that we have been using incompatible with it.
We use TypeGuard to ensure that `service_bot_tuples` is correctly
inferred to be `Tuple[int, int]` instead of `Tuple[int, Optional[int]]`.
Given that `bot_type` is optional for `ActiveUserDict`, we need to
narrow `row` to `ActiveBotUserDict` to make sure that `bot_type` is
non-optional. An advantage of this approach is that no assertions or
type casts are needed.

This commit removes "role" field from subscription
objects since we are not moving forward with stream
administrator concept and instead working on new
permssions model as per #19525.
As discussed in the new comments results in a better failure mode if
an error occurs while adding subscriptions; running the merge tool
again after fixing whatever caused the error will work just fine.
This ensure that the return type is compatible with the
actual type of `realm.realmdomain_set.values`.

To explain the rationale of this change, for example, there is
`get_user_activity_summary` which accepts either a `Collection[UserActivity]`,
where `QuerySet[T]` is not strictly `Sequence[T]` because its slicing behavior
is different from the `Protocol`, making `Collection` necessary.
Similarily, we should have `Iterable[T]` instead of `List[T]` so that
`QuerySet[T]` will also be an acceptable subtype, or `Sequence[T]` when we
also expect it to be indexed.

We were blindly adding / removing flag from UserMessages without
check if they even need to be updated.
This caused server to repeatedly update flags for messages which
already had been updated, creating a confusion for other clients
like mobile.
Fixes#22164
Sometimes (e.g. when moving an old realm out of the way of an import
into that name) we do *not* wish to add a redirect realm. Add a flag
to support that.
When there is no topic/stream being change, `propagate_mode` becomes
unnecessary. We add an assertion to ensure that the previous assumption
that `propagate_mode` is not `None` still holds when either `topic_name`
or `new_stream` is not `None`.
We can possibly improve this by overloading `do_update_message` and
`check_update_message`, but that's beyond the scope of the PR and
feasibility of doing that should also be further discussed.

When editing an old message in a private stream with protected
history, the server would incorrectly send an API event including the
edited message to all of the stream’s current subscribers, including
those who should not have access to the old message. This API event is
ignored by official clients, so it could only be observed by a user
using a modified client or their browser’s developer tools.

We remove one call to get_occupied_streams to get occupied
streams before unsubscribing because we already know which
streams can become vacant, i.e. the one from which users are
being unsubscribed, and we can directly use the list of streams
from which users are being unsubscribed and get vacant streams
by checking which of these streams are not in get_occupied_streams
called after unsubscribing users.
Previously, we were marking messages of all the streams passed
to bulk_remove_subscriptions even if user was not subscribed
to some of them and those streams would ideally not have
any unread messages. This code was added in 766511e519.
This commit changes the code to only mark messages of actually
unsubscribed streams as read.
cfcbf58cd1 rightly removed the use of `user_ids` in
`render_markdown`, which in turn makes it unnecessary in
`render_incoming_message`.
Remove the unnecessary parameter from `render_incoming_message`.
This commit changes the code to always pass delivery_email
field in the user's own object in 'realm_users'.
This commit also fixes the events sent by notify_created_user.
In the "realm_user/add" event sent when creating the user,
the delivery_email field was set according to the access
for the created user itself as the created user was passed as
acting_user to format_user_row. But now since we have changed
the code to always allow the user themselves to have access
to the email, this bug was caught in tests and we fix the person
object in the event to have delivery_email field based on whether
the user receiving the event has access to email or not.
This commit reads the browser locale during user registration, and
sets it as default language of user if it is supported by Zulip.
Otherwise, it is set to realm's default language.
`org_type` already exists as a field in the Realm model and is
used when organizations are created / updated in Zulip Cloud,
via the `/analytics/support` view.
Extends the `PATCH /realm` view to be able update `org_type` as
other realm / organization settings are updated, but using the
special log / action that was created for the analytics view.
Adds a field to the `realm op: update` / `realm op: update_dict`
events, which also means an event is now sent when and if the
`org_type` is updated via the analytics view. This is similar
to how updates to an organization's `plan_type` trigger events.
Adds `realm_org_type` as a realm setting fetched from the
`POST /register` endpoint.
This commit also adds 'subgroups' field to the user_group present
in the event sent on creating a user group. We do not allow passing
the subgroups while creating a user group as of this commit, but added
the field in the event object to pass tests.
This commit changes the invite API to accept invitation
expiration time in minutes since we are going to add a
custom option in further commits which would allow a user
to set expiration time in minutes, hours and weeks as well.
Based on an audit, this closes out the last core instances in which
acting_user was not being passed explicitly when creating
RealmAuditLog instances.
There are some outstanding issues in the billing system, which we plan
to extract as a separate issue.
Fixes#14808.
The `get_link_embed_data` / `link_embed_data_from_cache` pair as
introduced in c93f1d4eda uses the cache
as a temporary store inside of the `embed_links` worker; this means
that it must be durable storage, or the worker will stall and re-fetch
the same links to preview them.
Switch to plumbing through the fetched URL embed data as an parameter
to the Markdown evaluation which uses them, rather than using the
cache as an intermediary. This frees up the cache to be merely a
non-durable cache.
As a side-effect, this removes get_cache_with_key, and
link_embed_data_from_cache which was its only callsite.
