Mateusz Mandera c3a8a15bae delete_messages: Pass a list of user ids in the event in all cases.
The bulk deletion codepath was using dicts instead of user ids in the
event, as opposed to the other codepath which was adjusted to pass just
user ids before. We make the bulk codepath consistent with the other
one. Due to the dict-type events happening in 3.*, we move the goal for
deleting the compat code in process_notification to 5.0.

Mateusz Mandera 4235be759d CVE-2021-30477: Prevent outgoing webhook bots from sending arbitrary messages to any stream.
A bug in the implementation of replies to messages sent by outgoing
webhooks to private streams meant that an outgoing webhook bot could be
used to send messages to private streams that the user was not intended
to be able to send messages to.

Completely skipping stream access check in check_message whenever the
sender is an outgoing webhook bot is insecure, as it might allow someone
with access to the bot's API key to send arbitrary messages to all
streams in the organization. The check is only meant to be bypassed in
send_response_message, where the stream message is only being sent
because someone mentioned the bot in that stream (and thus the bot
posting there is the desired outcome). We get much better control over
what's going by passing an explicit argument to check_message when
skipping the access check is desirable.

Abhijeet Prasad Bodas 3947b0c80a linkifiers: Update API to send data using dictionaries.
* This introduces a new event type `realm_linkifiers` and
a new key for the initial data fetch of the same name.
Newer clients will be expected to use these.

* Backwards compatibility is ensured by changing neither
the current event nor the /register key. The data which
these hold is the same as before, but internally, it is
generated by processing the `realm_linkifiers` data.
We send both the old and the new event types to clients
whenever the linkifiers are changed.
Older clients will simply ignore the new event type, and
vice versa.

* The `realm/filters:GET` endpoint (which returns tuples)
is currently used by none of the official Zulip clients.
This commit replaces it with `realm/linkifiers:GET` which
returns data in the new dictionary format.
TODO: Update the `get_realm_filters` method in the API
bindings, to hit this new URL instead of the old one.

* This also updates the webapp frontend to use the newer
events and keys.

Abhijeet Prasad Bodas 8b098b95bb mute user: Mark as read old messages immediately.
When a user is muted, in the same request,
we mark any existing unreads from that user
as read.

This is done for all types of messages
(PM/huddle/stream) and regardless of whether
the user was mentioned in them.

This will not break the unread count logic
of the web frontend, because that algorithm
decides which messages to mark as read based
only on the pointer location and the whitespace
at the bottom, not on what messages have already
been marked as read.

Abhijeet Prasad Bodas 2f56f8d0ed mute user: Mark as read new messages.
Messages sent by muted users are marked as read
as soon as they are sent (or, more accurately,
while creating the database entries itself), regardless
of type (stream/huddle/PM).

ede73ee4cd, makes it easy to
pass a list to `do_send_messages` containing user-ids for
whom the message should be marked as read.
We add the contents of this list to the set of muter IDs,
and then pass it on to `create_user_messages`.

This benefits from the caching behaviour of `get_muting_users`
and should not cause performance issues long term.

The consequence is that messages sent by muted users will
not contribute to unread counts and notifications.

This commit does not affect the unread messages
(if any) present just before muting, but only handles
subsequent messages. Old unreads will be handled in
further commits.

Abhijeet Prasad Bodas 9602aa1467 mute user: Record entries in RealmAuditLog.
This makes it so that RealmAuditLog entries are
created when a user mutes/unmutes someone.

We don't really need to store the time, but we
do so anyways, because the `event_time` field
is currently a non-nullable one in the `RealmAuditLog`
model, and making it nullable would risk allowing
not specifying the time in other more important
code which also creates `RealmAuditLog` entries.

This also fixes an incorrect test of successfully
unmuting with the API. Earlier it did not mock
the time in the `views/muting.py` code to return
`mute_time`.

Abhijeet Prasad Bodas 152508e346 mute user: Reduce two database fetches when unmuting to one.
Previously, when unmuting a user, we used to make
two database fetches - one to verify that the user
is has been muted before, and one while actually
unmuting the user.

This reduces that to one, by passing around the
`MutedUser` object fetched in the first round.

Since the new function returns `Optional[MutedUser]`,
we need to use a hack for events tests, because
mypy does not yet use the type inferred from
`assert foo is not None` in nested functions like lambdas.
See python/mypy@8780d45507.

Signior-X f7aab9c92c send_message: Ensure sender receives message events first.
This commit implements a subtle optimization (described in more detail
in the comment) that can save a few hundred milliseconds in when the
sender sees that their message has sent when sending to very large
streams.

Fixes #17898.

Sumanth V Rao 1ac8fe7538 events/tests/api: Send realm_playground events to clients.
We send the whole data set as a part of the event rather than
doing an add/remove operation for couple of reasons:
    * This would make the client logic simpler.
    * The playground data is small enough for us to not worry
      about performance.

Tweaked both `fetch_initial_state_data` and `apply_events` to
handle the new playground event.

Tests added to validate the event matches the expected schema.

Documented realm_playgrounds sections inside /events and
/register to support our openapi validation system in test_events.

Tweaked other tests like test_event_system.py and test_home.py
to account for the new event being generated.

Lastly, documented the changes to the API endpoints in
api/changelog.md and bumped API_FEATURE_LEVEL.

Tweaked by tabbott to add an `id` field in RealmPlayground objects
sent to clients, which is essential to sending the API request to
remove one.

Sumanth V Rao d2e5b62dce realm/playground: Add API endpoint for deleting a playground entry.
Similar to the previous commit, we have added a `do_*` function
which does the deletion from the DB. The next commit handles sending
the events when both adding and deleting a playground entry.

Added the openAPI format data to zulip.yaml for DELETE
/realm/playgrounds/{playground_id}. Also added python and curl
examples to remove-playground.md.

Tests added.

Sumanth V Rao 251b415987 realm/playground: Add API endpoint for creating playground entry.
This endpoint will allow clients to create a playground entry
containing the name, pygments language and url_prefix for the
playground of their choice.

Introduced the `do_*` function in-charge of creating the entry in
the model. Handling the process of sending events which will be
done in a follow up commit.

Added the openAPI format data to zulip.yaml for POST
/realm/playgrounds. Also added python and curl examples for using
the endpoint in its markdown documented (add-playground.md).

Tests added.

Abhijeet Prasad Bodas 3bfcaa3968 mute user: Add backend infrastructure code.
Adds backend code for the mute users feature.
This is just infrastructure work (database
interactions, helpers, tests, events, API docs
etc) and does not involve any behavioral/semantic
aspects of muted users.

Adds POST and DELETE endpoints, to keep the
URL scheme mostly consistent in terms of `users/me`.

TODOs:
1. Add tests for exporting `zulip_muteduser` database table.
2. Add dedicated methods to python-zulip-api to be used
   in place of the current `client.call_endpoint` implementation.

LoopThrough-i-j ffd0d822fe actions: Send reaction events to subscribers with history access.
Previously, if a user subscribed to a stream with
history_public_to_subscribers, and then was looking at old messages in
the stream, they would not get live-updates for that stream, because
of the structure in how notify_reaction_update only looked at
UserMessage rows (we had a previous workaround involving the
`historical` field in `UserMessage` which had already made it work if
the user themselves added the reaction).

We fix this by including all subscribers with history access in the
set of recipients for update events.

Fixes a bug that was confused with #16942.

WookieMonkeys 1b6f68bb59 stream: Add entropy to deactivated streams.
Adding an additional `!` to the stream name each time a stream is
deactivated, to a maximum of 21 times, effectively limits number of
times a stream with a given name can be deactivated.  This is unlikely
to come up in common usage, but may be confusing when testing.

Change what we prepend to deactivated stream names to something with
more entropy than just `!`, by instead prepending a substring of hash
of the stream's ID.  `!`s.  Using 128 bits of the hash means that it
will require more than 10^18th renames to have a 1% chance of collision.

Because too-long stream names are also truncated at 60 characters,
having this entropy in the beginning of the name also helps address
potential issues from stream names that differed only in, e.g. the
60th character.

Fixes #17016.

Mateusz Mandera 353e1a2016 migrations: Subscription.is_user_active denormalization - final step.
With the previous two commits deployed, we're ready to use the
denormalization to optimize the query.

With dev environment db prepared using
./manage.py populate_db --extra-users=2000 --extra-streams=400
this takes the execution time of the query in
bulk_get_subscriber_user_ids from 1.5-1.6s to 0.4-0.5s on my machine.

Tim Abbott 53ed759fc1 users: Fix ordering issue with deactivating bots.

by a retry; if we deactivate the user first, then we may leak
undeactivated bots if a failure occurs.

savepoints where they aren't needed.
