Zixuan James Li 84723654c8 webhooks: Use 200 status code for unknown events.
Because the third party might not be expecting a 400 from our
webhooks, we now instead use 200 status code for unknown events,
while sending back the error to Sentry. Because it is no longer an error
response, the response type should now be "success".

Fixes #24721.

Alex Vandiver 1285c39098 zerver: Remove now-unused report/ endpoints. 2023-05-09 13:16:28 -07:00
Lauryn Menard e9bfdd1bf2 response: Implement ignored parameters with MutableJsonResponse class.
Creates `MutableJsonResponse` as a subclass of Django's `HttpResponse`
that we can modify for ignored parameters in the response content.

Updates responses to include `ignored_parameters_unsupported` in
the response data through `has_request_variables`. Creates unit
test for this implementation in `test_decorators.py`.

The `method` parameter processed in `rest_dispatch` is not in the
`REQ` framework, so for any tests that pass that parameter, assert
for the ignored parameter with a comment.

Updates OpenAPI documentation for `ignored_parameters_unsupported`
being returned in the JSON success response for all endpoints.
Adds detailed documentation in the error handling article, and
links to that page in relevant locations throughout the API docs.

For the majority of endpoints, the documentation does not include
the array in any examples of return values, and instead links to
the error handling page. The exceptions are the three endpoints
that had previously supported this return value. The changes note
and example for these endpoints is also used in the error
handling page.

Lauryn Menard b25cba16a7 tests: Remove ignored parameter from `authenticated_json_view` test.
The password parameter being passed in the `_do_test` helper
function for `TestAuthenticatedJsonPostViewDecorator` tests was
being ignored, as the user needs to be logged in. Removes the
parameter from the helper function and updates the success test
to use `assert_json_success` instead of just checking the status
code.

Also adds a test case for when a user is not logged in to confirm
that it returns an UnauthorizedError.

Alex Vandiver f8a16fb9af model: Handle parsed user-agents longer than 30 characters.
The Client.name field is only 30 characters long, but there is no
limit to the length of parsed User-Agent value which we may attempt to
store in it.  This can cause requests with long user-agents to 500
when the creation of the Client row fails.

Truncate the name at 30 characters for the cache key, and passing
`name` to `get_or_create`.

Sahil Batra 0ed5f76063 settings: Add backend code for using user email_address_visibility setting.
This commits update the code to use user-level email_address_visibility
setting instead of realm-level to set or update the value of UserProfile.email
field and to send the emails to clients.

Major changes are -

- UserProfile.email field is set while creating the user according to
RealmUserDefault.email_address_visbility.

- UserProfile.email field is updated according to change in the setting.

- 'email_address_visibility' is added to person objects in user add event
and in avatar change event.

- client_gravatar can be different for different users when computing
avatar_url for messages and user objects since email available to clients
is dependent on user-level setting.

- For bots, email_address_visibility is set to EVERYONE while creating
them irrespective of realm-default value.

- Test changes are basically setting user-level setting instead of realm
setting and modifying the checks accordingly.

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.

Zixuan James Li de22b72670 rate_limit: Remove rate_limit_ip.
Because rate_limit_request_by_ip is the only caller of it, it is safe
for us to inline RateLimitedIpAddr and remove this helper. This ensures
that we have consistent internals for rate limiting functions, which all
have a should_rate_limit check.

Zixuan James Li 26a518267a rate_limit: Replace rate_limit with inlined rate limit checks.
This change incorporate should_rate_limit into rate_limit_user and
rate_limit_request_by_ip. Note a slight behavior change to other callers
to rate_limit_request_by_ip is made as we now check if the client is
eligible to be exempted from rate limiting now, which was previously
only done as a part of zerver.lib.rate_limiter.rate_limit.

Now we mock zerver.lib.rate_limiter.RateLimitedUser instead of
zerver.decorator.rate_limit_user in
zerver.tests.test_decorators.RateLimitTestCase, because rate_limit_user
will always be called but rate limit only happens the should_rate_limit
check passes;

we can continue to mock zerver.lib.rate_limiter.rate_limit_ip, because the
decorated view functions call rate_limit_request_by_ip that calls
rate_limit_ip when the should_rate_limit check passes.

We need to mock zerver.decorator.rate_limit_user for SkipRateLimitingTest
now because rate_limit has been removed. We don't need to mock
RateLimitedUser in this case because we are only verifying that
the skip_rate_limiting flag works.

To ensure coverage in add_logging_data, a new test case is added to use
a web_public_view (which decorates the view function with
add_logging_data) with a new flag to check_rate_limit_public_or_user_views.

Zixuan James Li f158c86ae1 test_decorators: Rework RateLimitTestCase.
- RateLimitTestCase.get_ratelimited_view is replaced by a view
function directly decorated by public_json_view.

- the META dict is initialized with "PATH_INFO": "test" because now the
tests cover the process_client codepath;

- HostRequestMock is initialized with host="zulip.testserver" to pass
the validate_account_and_subdomain check;

- check_rate_limit_public_or_user_views replaces both
test_rate_limiting_happens_in_normal_case and
test_rate_limiting_happens_by_ip_if_unauthed.

Overall, we deduplicate the test cases in this change, and make sure
that they also cover the view function decorators for authentication.

authenticated_remote_server_view.

longer occurs anymore, since we don't perform subdomain checks on
remote servers.

Zixuan James Li c9f54766c3 rate_limiter: Extract rate limit related functions.
This refactors rate limit related functions from `zerver.decorator` to
zerver.lib.rate_limiter.

We conditionally import `RemoteZulipServer`, `RequestNotes`, and
`RateLimitedRemoteZulipServer` to avoid circular dependency.

Most instances of importing these functions from `zerver.decorator` got
updated, with a few exceptions in `zerver.tests.test_decorators`, where
we do want to mock the rate limiting functions imported in
`zerver.decorator`. The same goes with the mocking example in the
"testing-with-django" documentation.

This refactors `rate_limit` so that we no longer use it as a decorator.
This is a workaround to https://github.com/python/mypy/issues/12909 as
`rate_limit` previous expects different parameters than its callers.

Our approach to test logging handlers also needs to be updated because
the view function is not decorated by `rate_limit`.

Zixuan James Li b02779c005 request: Refactor remote_server into RequestNotes.
This eliminates the possibility of having `request.user` as
`RemoteZulipServer` by refactoring it as an attribute of `RequestNotes`.

So we can effectively narrow the type of `request.user` by testing
`user.is_authenticated` in most cases (except that of `SCIMClient`) in
code paths that require access to `.format_requestor_for_logs` where we
previously expect either `UserProfile` or `RemoteZulipServer` backed by
the implied polymorphism.

Tim Abbott 05b70ba74a decorator: Explicitly require req_secret in internal_notify_view.
It's hard to come up with a realistic story where this would matter:
SHARED_SECRET is generated automatically during server setup at the
same time as SECRET_KEY, which is a required setting, but it seems
preferable to be explicit that this is a required parameter for the
internal_notify authentication model.

This replaces user.is_verified with is_2fa_verified.

The helper does extra checks such that the user being checked for 2fa

`request.user.is_verified` is functionally the same as `is_verified`
from `django_otp.middleware`, except that the former is monkey-patched
onto the user object by the 2FA middleware. We use the latter wrapped
in `is_2fa_verified` instead to avoid accessing the patched attribute.
