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becomes outdated if the information is changed in any way.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.
This is a preparator refactor for supporting hosting different Tornado
processes on different servers; to look up which Tornado server we
should be sending the event to, we'll need the realm object.
When you send a message to a bot that wants
to talk via an outgoing webhook, and there's
an error (e.g. server is down), we send a
message to the bot's owner that links to the
message that triggered the error.
The code to produce those links was out of
date.
Now we move the important code to the
`url_encoding.py` library and fix the PM
links to use the more modern style (user_ids
instead of emails). We also replace "subject"
with "topic" in the stream urls.
Fixes the urgent part of #10397.
It was discovered that soft-deactivated users don't get mobile push
notifications for messages on private streams that they have configured
to send push notifications.
Reason: `handle_push_notification` calls `access_message`, and that
logic assumes that a user who is a recipient of a message has an
associated UserMessage row. Those UserMessage rows are created
lazily for soft-deactivated users, so they might not exist (yet)
until the user comes back.
Solution: Ensure that userMessage row is created for
stream_push_user_ids and stream_email_user_ids in create_user_messages.
This extends a test that proved only what Cordelia
could do with/without super_user privileges when she
was trying to send to an unsubscribed stream as herself.
Now the test shows the same powers extend to Cordelia
when she's sending messages on behalf of a mirrored
user.
We simulate a race condition by mocking create_user
to actually create a user, but then raise an
IntegrityError (as if another process had actually
created the user, not our test).
I also changed the real code to use explicitly
named parameters.
We want our methodology for extracting the last message
id to be consistent, particularly in terms of how we
handle edge cases. (I'll concede that the
`bulk_remove_subscriptions` codepath never hits that
corner case in practice, but it's harmless to handle
the theoretical case.)
It may also be nice to have this function show up
clearly in profiling.
This also adds some direct testing to the function.
It's not clear to me why we don't use `latest('id')`
in the implementation, but that's outside the scope
of this commit.
The use_first_unread_anchor parameter allows automatically setting the
anchor to the first message that hasn't been read in this narrow.
Therefore it isn't necessary to specify an anchor when this parameter is
enabled.
Note from Tim: Arguably, we should think about making
`use_first_unread_anchor` the default behavior when anchor is
unspecified, but that's for later consideration.
When GETting an unedited message's edit history, the server wasn't able
to reply properly and produced a 500 error.
Now when that happens, we return a message history that only contains
the original message.
Move the zcommands from '/views/messages.py' to
'/lib/zcommand'.
Also, move the zcommand tests from '/tests/test_messages.py'
to '/tests/test_zcommand'.
This fixes an issue where if you make #announce (the default
announcement stream) announce-only, then creating a new stream will
throw an exception (because notification-bot can't send there).
Fixes#9636.
These two slash commands now use zcommand to talk to
the server, so we have no Message overhead, and if you're
on a stream, you no longer spam people by accident.
The commands now also give reasonable messages
if you are already in the mode you ask for.
It should be noted that by moving these commands out of
widget.py, they are no longer behind the ALLOW_SUB_MESSAGES
setting guard.
This adds a /ping command that will be useful for users
to see what the round trip to the Zulip server is (including
only a tiny bit of actual server time to basically give a
200).
It also introduce the "/zcommand" endpoint and zcommand.js
module.
This removes a check on invite_only, that should have been a check on
history_public_to_subscribers. In addition to fixing a bug for zephyr
realms, it also makes "more topics" work correctly for realms using
the new settings for stream history being public to subscribers.
This commit adds a new field history_public_to_subscribers to the
Stream model, which serves a similar function to the old
settings.PRIVATE_STREAM_HISTORY_FOR_SUBSCRIBERS; we still use that
setting as the default value for new streams to avoid breaking
backwards-compatibility for those users before we are ready with an
actual UI for users to choose directly.
This also comes with a migration to set the value of the new field for
existing streams with an algorithm matching that used at runtime.
With significant changes by Tim Abbott.
This is an initial part of our efforts on #9232.
The removed code path was only needed due to buggy setup code in the
test_cross_realm_scenarios test. We address that with a less buggy
workaround, and which lets us remove unnecessary complexity from this
important validation function.
Thanks for Umair Waheed for some preliminary work on this.
Fixes#7561.
Add realm setting to set time limit for message deleitng.
Set default value of message_content_delete_limit_seconds
to 600 seconds(10 min).
Thanks to Shubham Dhama for rebasing and reworking this. Some final
edits also done by Tim Abbott.
Fixes#7344.
We should still short-circuit the iteration in
`add_missing_messages` if the unsubscription was the last
thing to happen to the user before unsubscription and
soft deactivation.
Applies the logic to allow community members to edit topics
of others' messages if this setting is True. Otherwise,
only administrators can update the topic of others' messages.
This logic includes a 24-hour time limit for community topic editing.
