Anders Kaseorg 2d9b2a2a05 models: Remove type prefixes from __str__ values.
The Django convention is for __repr__ to include the type and __str__
to omit it.  In fact its default __repr__ implementation for models
automatically adds a type prefix to __str__, which has resulted in the
type being duplicated:

    >>> UserProfile.objects.first()
    <UserProfile: <UserProfile: emailgateway@zulip.com <Realm: zulipinternal 1>>>

Lauryn Menard 084dd216f0 tests: Remove ignored `realm_str` parameter from message send test.
In commit 8181ec4b56, we removed the `realm_str` as a parameter
for `send_message_backed`. This removes a missed test that included
this as a parameter for that endpoint/function.

Sahil Batra 3950a8e19d test_helpers: Rename reset_emails_in_zulip_realm.
This commit renames reset_emails_in_zulip_realm function to
reset_email_visibility_to_everyone_in_zulip_realm which makes
it more clear to understand what the function actually does.

This commit also adds a comment explaining what this function
does.

Mateusz Mandera f0f02d05ab send_message_backend: Remove the realm_str API param.
This already became useless in 6e11754642,
as detailed in the API changelog entry here. At this point, we should
eliminate this param and the weird code around it.

This commit also deletes the associated tests added in
6e11754642, since with realm_str removed,
they make no sense anymore (and actually fail with an OpenAPI error due
to using params not used in the API). Hypothetically they could be
translated to use the subdomain= kwarg, but that also doesn't make
sense, since at that point they'd be just testing the case of a user
making an API request on a different subdomain than their current one
and that's just redundant and already tested generally in
test_decorators.

Alex Vandiver f78c2eab2c message_send: Use stream object for name in "no subscribers" message.
In the case where a stream existed but had no subscribers, the error
message used to send to the owner always used `stream_name`, which
may have been None.

Switch to using `stream.name` rather than `stream_name` for this case.

Lauryn Menard 06dd6f8254 message-send: Deduplicate check of `settings.MAX_MESSAGE_LENGTH`.
Removes the initial check in `_internal_prep_message` of the length
of the message content because the `check_message` in the try block
will call `normalize_body` on the message content string, which
does a more robust check of the message content (empty string, null
bytes, length). If the message content length exceeds the value of
`settings.MAX_MESSAGE_LENGTH`, then it is truncated based on that
value. Updates associated backend test for these changes.

The removed length check would truncate the message content with a
hard coded value instead of using the value for
`settings.MAX_MESSAGE_LENGTH`.

Also, removes an extraneous comment about removing null bytes. If
there are null bytes in the message content, then `normalize_body`
will raise an error.

Note that the previous check had intentionally reduced any message over
the 10000 character limit to 3900 characters, with the code in
question dating to 2012's 100df7e349.

The 3900 character truncating rule was implemented for incoming emails
with the email gateway, and predated other features to help with
overly long messages (better stripping of email footers via Talon,
introduced in f1f48f305e, and
condensing, introduced in c92d664b44).
While we could preserve that logic if desired, it likely is no longer
a necessary or useful variation from our usual truncation rules.

Alex Vandiver 8998aa00cd Revert "create_user: Use transaction.atomic decorator for do_create_user."
This reverts commit 851d68e0fc.

That commit widened how long the transaction is open, which made it
much more likely that after the user was created in the transaction,
and the memcached caches were flushed, some other request will fill
the `get_realm_user_dicts` cache with data which did not include the
new user (because it had not been committed yet).

If a user creation request lost this race, the user would, upon first
request to `/`, get a blank page and a Javascript error:

    Unknown user_id in get_by_user_id: 12345

...where 12345 was their own user-id.  This error would persist until
the cache expired (in 7 days) or something else expunged it.

Reverting this does not prevent the race, as the post_save hook's call
to flush_user_profile is still in a transaction (and has been since
168f241ff0), and thus leaves the potential race window open.
However, it much shortens the potential window of opportunity, and is
a reasonable short-term stopgap.

Sahil Batra 851d68e0fc create_user: Use transaction.atomic decorator for do_create_user.
We change the do_create_user function to use transaction.atomic
decorator instead of using with block. Due to this change, all
send_event calls are made inside transaction.on_commit.

Some other changes -
- Remove transaction.atomic decorator from send_inital_realm_messages
since it is now called inside a transaction.
- Made changes in tests which tests message events and notifications
to make sure on_commit callbacks are executed.

Zixuan James Li 7dbd98d25c rest: Restrict access to json views via basic auth.
Previously, test cases or clients accessing /json/ views using HTTP
Basic Auth would be accepted, while we intended to only allow clients
authenticated with a session cookie to access these views.

This adds a check on the accessed path to avoid this possibility.

It seems unlikely that any API clients clients were taking advantage
of this unintended quirk; so we're not going to bother documenting
this bug fix as an API change. In any case, it should be trivial for
anyone affected to consult the documentation and then switch their
/json/foo URL to a correct /api/v1/foo URL.

Zixuan James Li 46329a2710 test_classes: Create a dedicate helper for query count check.
This adds a helper based on testing patterns of using the "queries_captured"
context manager with "assert_length" to check the number of queries
executed for preventing performance regression.

It explains the rationale of checking the query count through an
"AssertionError" and prints the queries captured as assert_length does,
but with a format optimized for displaying the queries in a more
readable manner.

Anders Kaseorg bd9a1dc971 tests: Consistently JSON-encode ‘to’ parameter
Although our POST /messages handler accepts the ‘to’ parameter with or
without JSON encoding, there are two problems with passing it as an
unencoded string.

Firstly, you’d fail to send a message to a stream named ‘true’ or
‘false’ or ‘null’ or ‘2022’, as the JSON interpretation is prioritized
over the plain string interpretation.

Secondly, and more importantly for our tests, it violates our OpenAPI
schema, which requires the parameter to be JSON-encoded.  This is
because OpenAPI has no concept of a parameter that’s “optionally
JSON-encoded”, nor should it: such a parameter cannot be unambiguously
decoded for the reason above.

Our version of openapi-core doesn’t currently detect this schema
violation, but after the next upgrade it will.

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.

Mateusz Mandera ec5e12ef4e tests: Fix some instances of logged in session polluting test state.
In these tests, the code ends up with a logged in session when it's
undesired - later on these tests make requests to a different subdomain
- where a logged in session is not supposed to exist. This leads to an
unintended, strange situation where request.user is a user from the old
subdomain but the request itself is to a *different* subdomain. This
throws off get_realm_from_request, which will return the realm from
request.user.realm - which is not what these tests want and can lead to
these tests failing when some of the production code being tested
switches to using get_realm_from_request instead of
get_realm(get_subdomain).

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.

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.

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.
