This is a performance optimization, since we can avoid doing work
related to wildcard mentions in the common case that the message can't
have any. We also add a unit test for adding wildcard mentions in a
message edit.
Then, find and fix a predictable number of previous misuses.
With a small change by tabbott to preserve backwards compatibility for
sending `yes` for the `forged` field.

This is a follow-up to b69213808a.
We now actually send messages from the notification_bot, which
is the real usecase for this code.
Also, this cleans up the code and removes needless asserts like
`assertNotEqual(zulip_realm, lear_realm)` making the test easier
to read.
Priviously, we rendered the topic links using the msg.sender.realm.
This resulted in issues with Zulip's internal bots not having access
to the realm_filters of the destination stream's realm. For example,
sending a message via the email gateway or notification would not
linkify any realm filters that a user would expect them to.
Fixes#1727.
With the server down, apply migrations 0245 and 0246. 0246 will remove
the pub_date column, so it's essential that the previous migrations
ran correctly to copy data before running this.
This was used as a helper to construct the final display_recipient when
fetching messages. With the new mechanism of constructing
display_recipient by fetching appropriate users/streams from the
database and cache, this shouldn't be needed anymore.
Instead of having the rather unclear type Union[str,
List[UserDisplayRecipient]] where display_recipient of message dicts was
involved, we use DisplayRecipientT (renamed from DisplayRecipientCacheT
- since there wasn't much reason to have the word Cache in there), which
makes it clearer what is the actual nature of the objects and gets rid
of this pretty big type declaration.
Since the display_recipients dictionaries corresponding to users are
always dictionaries with keys email, full_name, short_name, id,
is_mirror_dummy - instead of using the overly general Dict[str, Any]
type, we can define a UserDisplayRecipient type,
using an appropriate TypedDict.
The type definitions are moved from display_recipient.py to types.py, so
that they can be imported in models.py.
Appropriate type adjustments are made in various places in the code
where we operate on display_recipients.
The user information in display_recipient in cached message_dicts
becomes outdated if the information is changed in any way.
In particular, since we don't have a way to find all the message
objects that might contain PMs after an organization toggles the
setting to hide user email addresses from other users, we had a
situation where client might see inaccurate cached data from before
the transition for a period of up to hours.
We address this by using our generic_bulk_cached_fetch toolchain to
ensure we always are fetching display_recipient data from the database
(and/or a special recipient_id -> display_recipient cache, which we
can flush easily).
Fixes#12818.
Previously, our OpenAPI documentation validation was failing for some
endpoints because it didn't account for the `in: path` type of
parameter, resulting in a mismatch between what was declared via REQ
and what was declared in the OpenAPI docs.
We fix this by excluding the path type parameters in both places from
what's considered by documentation using the `path_only` flag.
I doubt this is the correct long-term fix; in particular, I don't
think we're actually running the validators for these path-only
parameters. The examples that exist today are all IDs with validators
for being non-negative numbers, but longer-term I think we'll want to
do something different (possibly at the REQ layer, see the TODO).
Previously, we didn't have validation to prevent editing certain flags
that don't make sense for a client to edit, like whether a user was
mentioned in a given message.
This isn't a security issue -- the user could only mess up their own
personal search results (etc.), but it does seem worth fixing to avoid
confusion for folks developing Zulip clients.
While we're at it, clearly document the situation in comments.
This makes the implementation of `get_realm` consistent with its
declared return type of `Realm` rather than `Optional[Realm]`.
Fixes#12263.

This enables the function to either return a valid UserProfile or raise
InvalidMirrorInput, which is clearer and more pythonic than the previous
approach of a tuple of a bool and Optional[UserProfile].
In making the type clearer, this improves checking with mypy.
Tests updated.
Extend the list of users that have to be notified when a message is
changed, so that in addition to users who have a UserMessage row, any
users who subscribed later to a stream with history public to
subscribers will also get the update.
Fixes: #8750.
This adds experimental support in /register for sending key
statistical data on the last 1000 private messages that the user is a
participant in. Because it's experimental, we require developers to
request it explicitly in production (we don't use these data yet in
the webapp, and it likely carries some perf cost).
We expect this to be extremely helpful in initializing the mobile app
user experience for showing recent private message conversations.
See the code comments, but this has been heavily optimized to be very
efficient and do all the filtering work at the database layer so that
we minimize network transit with the database.
Fixes#11944.
A user who has been soft deactivated for a long time might have 10Ks of message
history that was "soft deactivated". It might take a minute or more to add
UserMessage rows for all of these messages, causing timeouts. So, we paginate
the creation of these UserMessage rows.
For internal stream messages, most of the time, we have access to
a Stream object. For the few corner cases where we don't, it is a
much cleaner approach to have a separate function that accepts a
stream name than having one multi-option helper that accepts both
names and objects.
If the caller has access to a Stream object, it is wasteful to
query a database for a stream by ID or name. In addition, not
having to go through stream names eliminates various classes of
possible bugs involved with re-fetching the Stream object by name.
The name for_stream_name is more appropriate here. The name
for_stream is more suitable for a function that takes in a Stream
object, which we're about to add.
This is primarily a feature for onboarding, where an organization
administrator might send a bunch of random test messages as part of
joining, but then want a pristine organization when their users later
join.
But it can theoretically be used for other use cases (e.g. for
moderation or removing threads that are problematic in some way).
Tweaked by tabbott to handle corner cases with
is_history_public_to_subscribers.
Fixes#10912.
This commit also contains the following auxiliary changes:
* Adds a custom exception, StreamWithIDDoesNotExist for when
a stream with a given ID does not exist because the error
message returned by StreamDoesNotExist only makes with stream
names, not IDs.
* Adds a new helper, get_stream_by_id_in_realm, which is similar
to get_user_profile_by_id_in_realm (introduced in #10391).
* Adds a helper, validate_stream_id_with_pm_notification, which
returns the Stream object associated with a given ID and also
handles PM notifications to the bot owner if the message was
sent by a bot and if the stream does not exist or has no
subscribers.
* Modifies the message sent by send_pm_if_empty_stream to
accommodate stream IDs.
Note that all of the above changes are required before check_message
can be modified to support stream IDs.
Multiple delete message requests for the same message sometimes caused
a 500 error. This happened via the normal IntegrityError being thrown
by delete message/archiving code.
This was manually reproduced by adding latency in function
move_messages_to_archive() in retention.py and
delete_message_backend() in views.py. This addresses the problem by
adding code to handle the exception and throw JsonableError to convert
500 to 400 errors, with an automated test.
We make this change because setting up reminders in PM's didn't
play really well with our current infrastructure. Basically the
reminder messages from the bot can't appear in the same narrow as
that of a PM between two people and therefore we disable it.
Though we make an exception here where a person wants to set up
reminder for himself.
Change the truncation marker from `...` to `\n[message truncated]`
when receiving messages from the API or through e-mail. Also, update
tests to account for the new change.
Fix#10871.
