Added assertion to check that if a deprecated flag is in a field's
schema, then it should have deprecated mentioned in description
as well, and moved these checks to a separate function.
Fixes part of #15967.
Because of the very large `oneOf` clause of the formats of events
possible in Zulip's `GET /events` system, we had issues with
`test-backend` failures for missing documentation for a new event
format being like 1000 lines of output, which was very much unhelpful.
Fix this by limiting the output use only the oneOf variants that are
broadly similar to the actual payload received.
Fixes#16023.
As explained in the previous commit, yamole preprocessed allOf with an
algorithm that is not standards compliant. We replicate that
algorithm, but importantly, we only use it for our own code and not
for building the openapi_core RequestValidator.
This improves the time taken by OpenAPISpec().check_reload() from
1.69s to 0.53s, nearly all of which is inside
openapi_core.create_spec.
Closes#10484. Significantly improves #16068.

Previously there was a documented_events set which provided for partial
OpenAPI documentation while documentation was still going on. But since
the documentation is complete now, remove it.
Edit the function `validate_against_openapi_schema` and add some
helper functions to allow for validation of documented events.
Also add OpenAPI response validation in `verify_action` as it is
called in a large number of `/events` tests.
Change the condition for allowing failed validation to the condition
that `if the test fails, response status code begins with 4`. Also
add `intentionally_undocumented` argument in `validate_request` for
allowing passing of tests which return `200` responses but fail
validation due to some intentionally undocumented feature in
OpenAPI specification.
OpenAPISpec is our main class for accessing OpenAPI objects and
has the capability of creating the OpenAPI objects only once, thus
saving time. Since the openapi-core request validator object is going
to be accessed for considerable time during testing, hence add it to
the class for faster testing.
Our previous OpenAPI schema validator that we implemented ourselves
was useful training wheels for our understanding OpenAPI properly, and
was mostly correct. But given that we've finally reached the point
where our OpenAPI file accurately describes the API, it makes sense to
switch to use an official OpenAPI validator. We lose some ability to
do exclude rules for particular elements, but those were primarily
important for us when we had a lot of them.
As part of this change, we need to add `additionalProperties: false`
for all of our dictonaries/objects where we've documented every
parameter; otherwise the OpenAPI schema checker won't know that we
expect every parameter to be documented.
There is still some miscellaneous cleanup that
has to happen for things like analytics queries
and dead code in node tests, but this should
remove the main use of pointers in the backend.
(We will also still need to drop the DB field.)
In zulip.yaml, add `deprecated` tags to all parameters/keys with
`Deprecated` in the description. Then add tests to ensure that deprecated
parameters/keys will always have the `deprecated` key. Also, in
the API docs, sort the parameters according to presence of `deprecated`
key, presenting the `deprecated` keys at the end and add a `deprecated`
tag next to them.
The `EXCLUDE_PROPERTIES` is a dictionary in `zerver/openapi/openapi.py`
which holds the undocumented properties of our API. Document all
properties other than:
*`delivery_email` which is in another PR.
*'events' and 'register'.
*'/setting/notification' since its response is about to undergo heavy
changes.
We had a bug in `validate_against_openapi_schema` that prevented it
from correctly inspecting nested arrays.
Fix the bug and address all the exceptions, either via
EXCLUDE_PROPERTIES or fixing them when simple. Also add a test case
for nested verification.
This adds a powerful end-to-end test for Zulip's API documentation:
For every documented API endpoint (with a few declared exceptions that
we hope to remove), we verify that every API response received by our
extensive backend test suite matches the declared schema.
This is a critical step towards being able to have complete, high
quality API documentation.
Fixes#15340.

There seems to have been a confusion between two different uses of the
word “optional”:
• An optional parameter may be omitted and replaced with a default
value.
• An Optional type has None as a possible value.
Sometimes an optional parameter has a default value of None, or None
is otherwise a meaningful value to provide, in which case it makes
sense for the optional parameter to have an Optional type. But in
other cases, optional parameters should not have Optional type. Fix
them.

Currently there are no checks in validate_against_openapi_schema
to check whether the `content` it received actually matched with
the `response code`. For example during testing if a certain endpoint
was returning 400 but it was expected to return 200, then it would
pass schema validation as it would only have `msg` and `result` keys.
Add this validation and fix the wrong response returning points.
Add test to validate example responses in zulip.yaml. Also change
zulip.yaml for some wrong examples or for cases which were not
covered by `test-api`. Also enhance `validate_against_openapi_schema`.

Objects whose properties are not described were validated by the
current validator. Edit it so that objects with no `properties`
or `additionalProperties` attribute i.e. opaque objects get
invalidated.
Also make changes in zulip.yaml to fix any opaque objects (tweaked by
tabbott to edit the documentation for better clarity).
Currently, `validate_against_openapi_schema` checks only the top
level of the response dictionary. Improve it so that it can
validate objects and arrays at all levels. Also edit zulip.yaml
accordingly. And for new response keys which were not defined
before add VERY basic documentation.
Currently response return values have to be written twice, once in
the docs and once in zulip.yaml. Create a markdown extension so
that the return values in api docs are rendered using content from
zulip.yaml
Add function in openapi.py to access endpoint descriptions written
in zulip.yaml. Use this function for creating a markdown extension
for rendering endpoint descriptions written in zulip.yaml.
We use this extension for a single endpoint to get test coverage.
Openapi had descriptive response codes for endpoints with multiple
responses for same response code. But this does not fall in line
with openapi specifications. So change descriptive response codes
like "400_auth" and "400_anauth" to "400_0" and "400_1" for all
such endpoints. Also make the necessary changes in openapi.py so
as to be able to read the schema in such cases and generate example
in such cases.
