This commit removes WILDCARD_MENTION_POLICY_STREAM_ADMINS
option of wildcard_mention_policy since we are not moving
forward with stream administrator concept and instead working
on new permssions model as per #19525.
We also add a migration to change wildcard_mention_policy of
existing realms to WILDCARD_MENTION_POLICY_ADMINS. This change
is fine since we were already treating both the setting values
as same as stream admin concept was not implemented completely.
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.

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.

This commit adds the backend functionality to
mark messages as unread through update_message_flags
with `unread` flag and `remove` operation.
We also manage incoming events in the webapp.
Tweaked by tabbott to simplify the implementation and add an API
feature level update to the documentation.
This commit was originally drafted by showell, and showell
also finalized the changes. Many thanks to Suyash here for
the main work here, which was to get all the tests and
documentation work moving forward.
We want TypedDicts that have actual teeth.
In order to make type checks meaningful, we want
to avoid Any, object, or crazy Union types when
we aggregate each type of message, so we replaced
a generic function with three concrete functions.
Since we've changed the database to contain these new fields, we just
need to stop dropping them in the API code.
This also changes the public API to match the database format again
by removing `prev_subject` from edit history API.
Adds an API changelog feature update for the renamed `prev_subject`
field (to `prev_topic`) and new fields (`topic` and `stream`)
in the message `edit_history`.
Also, documents said `edit_history` in the `MessagesBase` schema
in the api documentation, which is used by the `/get-messages`,
`/get-events` and `/zulip-outgoing-webhooks` endpoints.
Fixes#21076.

We modify the message_edit_history marshalling code so that this
commit does not change the API, since we haven't backfilled the data
yet.
FormattedEditHistoryEvent, introduced in the previous commit, doesn't
directly inherit fields from EditHistoryEvent, so no changes are
required there.
These types will help make iteration on this code easier.
Note that `user_id` can be null due to the fact that
edit history entries before March 2017 did not log
the user that made the edit, which was years after
supporting topic edits (discovered in test deployment
of migration on chat.zulip.org).

Previously, users found it annoying that the automated "Resolve topic"
notifications triggered an unread for everyone in the stream; this
discouraged some users from using the feature on older threads for
fear of being annoying. We change this to a better default, of only
users who participated in the topic (via either messages or reactions)
being eligible for the new message being unread.
We will likely want to create global and stream-level notifications
settings to control this behavior as a follow-up -- some users, like
me, might prefer the simpler "Always unread" behavior in some streams.
Note that the automated notifications that a topic was resolved will
still result in the topic being moved to the top of the left sidebar.
This would be somewhat difficult to change, since the left sidebar
algorithm just looks at the highest message ID in the topic.
Fixes#19709.

This replaces the temporary (and testless) fix in
24b1439e93 with a more permanent
fix.
Instead of checking if the user is a bot just before
sending the notifications, we now just don't enqueue
notifications for bots. This is done by sending a list
of bot IDs to the event_queue code, just like other
lists which are used for creating NotificationData objects.
Credit @andersk for the test code in `test_notification_data.py`.
We make zero invalid value for message_content_delete_limit_seconds and
for handling the case of "Allow to delete message any time", the API-level
value of message_content_delete_limit_seconds is "anytime" and "None"
as the DB-level value. We also use these values for message retention
setting, so it helps maintain consistency.
These changes are all independent of each other; I just didn’t feel
like making dozens of commits for them.

Previously, we checked for the `enable_offline_email_notifications` and
`enable_offline_push_notifications` settings (which determine whether the
user will receive notifications for PMs and mentions) just before sending
notifications. This has a few problem:
1. We do not have access to all the user settings in the notification
handlers (`handle_missedmessage_emails` and `handle_push_notifications`),
and therefore, we cannot correctly determine whether the notification should
be sent. Checks like the following which existed previously, will, for
example, incorrectly not send notifications even when stream email
notifications are enabled-
```
if not receives_offline_email_notifications(user_profile):
return
```
With this commit, we simply do not enqueue notifications if the "offline"
settings are disabled, which fixes that bug.
Additionally, this also fixes a bug with the "online push notifications"
feature, which was, if someone were to:
* turn off notifications for PMs and mentions (`enable_offline_push_notifications`)
* turn on stream push notifications (`enable_stream_push_notifications`)
* turn on "online push" (`enable_online_push_notifications`)
then, they would still receive notifications for PMs when online.
This isn't how the "online push enabled" feature is supposed to work;
it should only act as a wrapper around the other notification settings.
The buggy code was this in `handle_push_notifications`:
```
if not (
receives_offline_push_notifications(user_profile)
or receives_online_push_notifications(user_profile)
):
return
// send notifications
```
This commit removes that code, and extends our `notification_data.py` logic
to cover this case, along with tests.
2. The name for these settings is slightly misleading. They essentially
talk about "what to send notifications for" (PMs and mentions), and not
"when to send notifications" (offline). This commit improves this condition
by restricting the use of this term only to the database field, and using
clearer names everywhere else. This distinction will be important to have
non-confusing code when we implement multiple options for notifications
in the future as dropdown (never/when offline/when offline or online, etc).
3. We should ideally re-check all notification settings just before the
notifications are sent. This is especially important for email notifications,
which may be sent after a long time after the message was sent. We will
in the future add code to thoroughly re-check settings before sending
notifications in a clean manner, but temporarily not re-checking isn't
a terrible scenario either.
The reason for this bug is because of different striping
processes in the backend and frontend, i.e The frontend
checks if the message's `raw_content` has changed to
decide if the `content` of the message should be sent in
the request to the backend, or not. So, it removes the
leading new line ('\n') from the message `raw_content`
when checking it, which is causing the "Error saving edit:
You don't have permission to edit this message" error.
This commit fixes it by removing the leading new line
when cleaning message content.
The bug was explained by @punchagan and its solution
by @timabbott.
We will later use this data to include text like:
`<sender> mentioned @<user_group>` instead of the current
`<sender> mentioned you` when someone mentions a user group
the current user is a part of in email/push notification.
Part of #13080.
This adds a new class called MessageRenderingResult to contain the
additional properties we added to the Message object (like alert_words)
as well as the rendered content to ensure typesafe reference. No
behavioral change is made except changes in typing.
This is a preparatory change for adding django-stubs to the backend.

Further commits will start locking the message rows while
adding related fields like reactions or submessages,
to handle races caused by deleting the message itself at the
same time.
The message locking implemented then will create a possibility
of deadlocks, where the related field transaction holds a lock
on the message row, and the message-delete transaction holds a
lock on the database row of the related field (which will also
need to be deleted when the message is deleted), and both
transactions wait for each other.
To prevent such a deadlock, we lock the message itself while
it is being deleted, so that the message-delete transaction
will have to wait till the other transaction (which is about
to delete the related field, and also holds a lock on the
message row) commits.

This will offer users who are self-hosting to adjust
this value. Moreover, this will help to reduce the
overall time taken to test `test_markdown.py` (since
this can be now overridden with `override_settings`
Django decorator).
This is done as a prep commit for #18641.
The old name `push_notify_user_ids` was misleading, because
it does not contain user ids which should be notified for
the current message, but rather user ids who have the online
push notifications setting enabled.
When the Tornado server is restarted during an upgrade, if
server has old events with the `push_notify_user_ids` fields,
the server will throw error after this rename. Hence, we need
to explicitly handle such cases while processing the event.

This completes the effort to make it possible to use
bulk_access_message in contexts where there are more than a handful of
messages without creating performance issues.
If the caller has already fetched the Stream or subscription details
for the user, those can be passed to has_message_access to avoid extra
database queries.
model__id syntax implies needing a JOIN on the model table to fetch the
id. That's usually redundant, because the first table in the query
simply has a 'model_id' column, so the id can be fetched directly.
Django is actually smart enough to not do those redundant joins, but we
should still avoid this misguided syntax.
The exceptions are ManytoMany fields and queries doing a backward
relationship lookup. If "streams" is a many-to-many relationship, then
streams_id is invalid - streams__id syntax is needed. If "y" is a
foreign fields from X to Y:
class X:
y = models.ForeignKey(Y)
then object x of class X has the field x.y_id, but y of class Y doesn't
have y.x_id. Thus Y queries need to be done like
Y.objects.filter(x__id__in=some_list)
django.utils.translation.ugettext is a deprecated alias of

This is preparatory work for investigating reports of missing unread
messages.
It's a little surprising that not test failed after adding the code
without API documentation.
