This commit completes the notifications part of the @topic
wildcard mention feature.
Notifications are sent to the topic participants for the
@topic wildcard mention.
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.
This is a first step toward two goals:
* support dictionary-like narrows when registering events
* use readable dataclasses internally
This is gonna be a somewhat complicated exercise due to how
events get serialized, but fortunately this interim step
doesn't require any serious shims, so it improves the codebase
even if the long-term goals may take a while to get sorted
out.
The two places where we have to use a helper to convert narrows
from tuples to dataclasses will eventually rely on their callers
to do the conversion, but I don't want to re-work the entire
codepath yet.
Note that the new NarrowTerm dataclass makes it more explicit
that the internal functions currently either don't care about
negated flags or downright don't support them. This way mypy
protects us from assuming that we can just add negated support
at the outer edges.
OTOH I do make a tiny effort here to slightly restructure
narrow_filter in a way that paves the way for negation support.
The bigger goal by far, though, is to at least support the
dictionary format.
We no longer pass in a big opaque event to narrow_filter
(which is inside build_narrow_filter). We instead explicitly
pass in message and flags. This leads to a bit more type
safety, and it's also more flexible. There's no reason to
build an entire event just to see if a message belongs to
a narrow.
The changes to the test work around the fact that the fixtures
are sloppy with types. I plan a subsequent commit to clean
up those tests significantly.
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 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.
In #23380 we want to replace all occurrences of `uri` with `url`.
This commit replaces the occurrences appeared in a variable name
`tornado_uri` and a function name `get_tornado_uri`.
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.
Fixes#23124.

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.
This code is called in the hot path when Tornado is processing events.
As such, making this code performant is important. Profiling shows
that a significant portion of the time is spent calling asdict() to
serialize the UserMessageNotificationsData dataclass. In this case
`asdict` does several steps which we do not need, such as attempting
to recurse into its fields, and deepcopy'ing the values of the fields.
In our use case, these add a notable amount of overhead:
```py3
from zerver.tornado.event_queue import UserMessageNotificationsData
from dataclasses import asdict
from timeit import timeit
o = UserMessageNotificationsData(1, False, False, False, False, False, False, False, False, False, False, False)
%timeit asdict(o)
%timeit {**vars(o)}
```
Replace the `asdict` call with a direct access of the fields. We
perform a shallow copy because we do need to modify the resulting
fields.
Black 23 enforces some slightly more specific rules about empty line
counts and redundant parenthesis removal, but the result is still
compatible with Black 22.
(This does not actually upgrade our Python environment to Black 23
yet.)

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.
Fixes: #22884
Doing rapid pace mark-as-unread in the Zulip web application, one
observed assertion failures showing that the server would send an
event containing multiple message IDs but only one of the messages
present in the message_details side data structure.
The cause of this was the "virtual events" compression system; two
flags/remove/read events were being combined by simply concatenating
the lists of events, without any attempt to merge the
`message_details` field on those objects.
The immediate fix is to disable virtual events compression for this
event class, but it's not unlikely we'll need to just eliminate the
virtual_events system entirely, because it seems difficult to make it
soundly handle a message whose state for a given flag changes back and
forth while the client is offline.
But we'll leave that for later, since removing that optimization
deserves more discussion than fixing this event corruption bug.
return inside finally blocks causes exceptions to be silenced.
Although these blocks follow blanket ‘except Exception’ handlers, they
do not seem to have a goal of silencing BaseException and exceptions
thrown by the exception handler, so rewrite them to avoid it.

Mobile clients older than v27.192 do not support PRONOUNS type
custom profile fields, so we instead change the type of it to
SHORT_TEXT in the data sent with register response and also in
the events sent to those clients.
One should now be able to configure a regex by appending _regex to the
port number:
[tornado_sharding]
9802_regex = ^[l-p].*\.zulipchat\.com$

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.
Instead of using `request.POST` to access the `data` parameter used
in the internal `notify_tornado` path, adds `has_request_variables`
decorator and accesses `data` as a `REQ` parameter.
Expands `test_tornado_endpoint` in `test_event_system.py` for
`data` being a required parameter for this path.
This was for the old /messages/latest API that was removed in commit
e06722657a.
If we wanted a new check like this, it shouldn’t go in zulip_finish,
because that only runs when the client gets an asynchronous response
from polling an initially-empty queue, and not when the client gets a
synchronous response from polling a nonempty queue.

For the same reason as `handler_id` has, we define `_request`
as an attribute. Note that the name `request` is already taken.

This prevents us from relying on a side-effect of `allocate_handler_id`
that monkey-patches `handler_id` on the `AsyncDjangoHandler` object,

Commit 6fd1a558b7 (#21469) introduced an
await point where get_events_backend calls fetch_events in order to
switch threads. This opened the possibility that, in the window
between the connect_handler call in fetch_events and the old location
of this assignment in get_events_backend, an event could arrive,
causing ClientDescriptor.add_event to crash on missing
handler._request. Fix this by assigning handler._request earlier.
