Sahil Batra 9f0d498994 message: Check mandatory_topics setting in backend as well.
Previously, we only checked mandatory_topics setting before
sending message in frontend and there was no restriction in
backend. This commit adds the check in backend also making
sure messages without topic cannot be sent through API as
well if mandatory_topics setting is set to True.

Alex Vandiver df50280c54 string_validation: Loosen to allow some `Cn` unicode characters.
Under the unicodedata distributed with Python 3.6, some Emoji are
classified as `Cn`, and not `So`:

```
$ unicode 1f929 --long
U+1F929 GRINNING FACE WITH STAR EYES
UTF-8: f0 9f a4 a9 UTF-16BE: d83edd29 Decimal: 🤩 Octal: \0374451
🤩
Category: So (Symbol, Other); East Asian width: W (wide)
Unicode block: 1F900..1F9FF; Supplemental Symbols and Pictographs
Bidi: ON (Other Neutrals)

$ python3.6 -c 'import unicodedata; print(unicodedata.category("\U0001f929"))'
Cn

$ python3.7 -c 'import unicodedata; print(unicodedata.category("\U0001f929"))'
So
```

Drop `Cn` from the list of excluded Unicode character classes, and
replace it with an explicit list of the 66 non-characters, which are
invariant.

Eeshan Garg c30458e174 streams: Add notifications for posting policy changes.
An explanatory note on the changes in zulip.yaml and
curl_param_value_generators is warranted here. In our automated
tests for our curl examples, the test for the API endpoint that
changes the posting permissions of a stream comes before our
existing curl test for adding message reactions.

Since there is an extra notification message due to the change in
posting permissions, the message IDs used in tests that come after
need to be incremented by 1.

This is a part of #20289.

Shlok Patel b3c58f454f api: Prevent special characters in topics.
Special characters, including `\r`, `\n`, and more esoteric codepoints
like non-characters, can negatively affect rendering and UI behaviour.

Check for, and prevent making new messages with, characters in the
Unicode categories of `Cc` (control characters), `Cs`, (surrogates),
and `Cn` (unassigned, non-characters).

Fixes #20128.

Riken Shah a96c614420 message: Fix the edit topic bug by removing leading \n from msg content.
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.

akshatdalton 7df62ebbaf settings: Make `MAX_MESSAGE_LENGTH` a server-level setting.
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.

This commit modifies the test_wildcard_mention_restrictions test

WILDCARD_MENTION_POLICY_ADMINS. Previously, we were checking
for members, but it is better to check for moderators.

Mateusz Mandera 6e11754642 CVE-2021-30478: Prevent API super users from forging messages to other organizations.
A bug in the implementation of the can_forge_sender permission
(previously is_api_super_user) resulted in users with this permission
being able to send messages appearing as if sent by a system bots,
including to other organizations hosted by the same Zulip installation.

- The send message API had a bug allowing an api super user to
  use forging to send messages to other realms' streams, as a
  cross-realm bot. We fix this most directly by eliminating the
  realm_str parameter - it is not necessary for any valid current use
  case. The email gateway doesn't use this API despite the comment in
  that block suggesting otherwise.
- The conditionals inside access_stream_for_send_message are changed up
  to improve security. They were generally not ordered very well,
  allowing the function to successfully return due to very weak
  acceptance conditions - skipping the higher importance checks that
  should lead to raising an error.
- The query count in test_subs is decreased because
  access_stream_for_send_message returns earlier when doing its check
  for a cross-realm bot sender - some subscription checking queries are
  skipped.
- A linkifier test in test_message_dict needs to be changed. It didn't
  make much sense in the first place, because it was creating a message
  by a normal user, to a stream outside of the user's realm. That
  shouldn't even be allowed.

their names.

I also updated the Node, Puppeteer, Backend tests and Fixtures to
support this change.

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.

sahil839 15e74a637c tests: Check cases when full members and their bots can send messages.
Currently there are only tests for verifying the error case and there
are no tests to check the case where messages are sent successfully
in 'STREAM_POST_POLICY_RESTRICT_NEW_MEMBERS' stream.

This commit adds tests for checking that full members and bots owned
by them can send message successfully in streams with post policy as
'STREAM_POST_POLICY_RESTRICT_NEW_MEMBERS'.

sahil839 3df87d0901 stream: Fix error handling in access_stream_for_send_message.
According to tests we should not allow bot without owners to
post in streams with STREAM_POST_POLICY_RESTRICT_NEW_MEMBERS.
But the code does not handle this and the related test passes
and raises error for case of bots without owner because the bot
is itself a new member.

This commit fixes this by adding a condition to check if there
is no bot owner and then raise error if there is no owner.

Mateusz Mandera bf9e5e52ce dependencies: Upgrade to Django 3.0.
Adjustments made due to changes in Django 3.0:

- test_signup: INTERNAL_RESET_URL_TOKEN was moved to
  PasswordResetConfirmView.reset_url_token
- test_message_fetch:
  "add_never_cache_headers() and never_cache() now add the private
  directive to Cache-Control headers."
- "django.utils.html.escape() now uses html.escape() to escape HTML.
  This converts ' to &#x27; instead of the previous equivalent decimal
  code &#39;." - this requires adjusting the expected decimal code
  in some of the string fixtures in tests.

sahil839 2fa33be683 actions: Refactor check_message to change return dataclass instead of Dict.
We change the return type of check_message to be dataclass instead of
Dict[str, Any]. This refactoring helps us to understand the context of the
data structure returned by check_message clearly which was not possible
when using Dict.

SendMessageRequest class is added in zerver/lib/message.py inspite of it
not being used in that file itself just to maintain consistency as other
TypedDicts and dataclasses are defined in that file and to avoid circular
dependency as SendMessageRequest is being used in lib/widget.py as well.

We also rename local variable to 'send_request' for accessing
SendMessageRequest objects.

Steve Howell c1f134a3a4 performance: Use ORM to fetch sender in render_markdown.
In 709493cd75 (Feb 2017)
I added code to render_markdown that re-fetched the
sender of the message, to detect whether the message is
a bot.

It's better to just let the ORM fetch this.  The
message object should already have sender.

The diff makes it look like we are saving round trips
to the database, which is true in some cases.  For
the main message-send codepath, though, we are only
saving a trip to memcached, since the middleware
will have put our sender's user object into the
cache.  The test_message_send test calls internally
to check_send_stream_message, so it was actually
hitting the database in render_markdown (prior to
my change).

Steve Howell 85ed6f332a performance: Avoid Recipient lookup for stream messages.
All the fields of a stream's recipient object can
be inferred from the Stream, so we just make a local
object.  Django will create a Message object without
checking that the child Recipient object has been
saved.  If that behavior changes in some upgrade,
we should see some pretty obvious symptom, including
query counts changing.

Tweaked by tabbott to add a longer explanatory comment, and delete a
useless old comment.

message_send: Fix old guests being treated as full members.
For streams in which only full members are allowed to post,
we block guest users from posting there.

Guests users were blocked from posting to admin only streams
already. So now, guest users can only post to

This is not a new feature but a bugfix which should have
