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.
