Apparently, our new validator for stream color having a valid format
incorrectly handled colors that had duplicate characters in them.
(This is caused in part by the spectrum.js logic automatically
converting #ffff00 to #ff0, which our validator rejected). Given that
we had old stream colors in the #ff0 format in our database anyway for
legacy, there's no benefit to banning these colors.
In the future, we could imagine standardizing the format, but doing so
will require also changing the frontend to submit colors only in the
6-character format.
Fixes an issue reported in
https://github.com/zulip/zulip/issues/11845#issuecomment-471417073
Add `max_int_size` parameter to `to_non_negative_int()` in
decorator.py so it will be able to validate that the integer doesn't
exceed the integer maximum limit.
Fixes#11451
API users, particularly bots, can now send a field
called "widget_content" that will be turned into
a submessage for the web app to look at. (Other
clients can still rely on "content" to be there,
although it's up to the bot author to make the
experience good for those clients as well.)
Right now widget_content will be a JSON string that
encodes a "zform" widget with "choices." Our first
example will be a trivia bot, where users will see
something like this:
Which fruit is orange in color?
[A] orange
[B] blackberry
[C] strawberry
The letters will be turned into buttons on the webapp
and have canned replies.
This commit has a few parts:
- receive widget_content in the request (simply
validating that it's a string)
- parse the JSON in check_message and deeply
validate its structure
- turn it into a submessage in widget.py
The main thing here is writing check_string_fixed_length and
check_capped_string as returning a Validator, but we also fix issues
around passing default=None.
We were rejecting strings of length equal to the max.
While we're at it, fix the unnecessary period in the error message,
which doesn't align with similar validators.
These changes are in one commit, since the previous typing of check_url
does not match the centralized strict definition (object/Any vs Text),
actually already used elsewhere in validator.py, and also had a different
API.
check_url is updated here to match the API of the other check_* functions,
ie. val is an object (not Text) & returns Optional[str]. It also now checks
the value is text explicitly at run-time, which was only type-checked
previously. Tests are updated accordingly.
For EventsRegisterTest that test updates to streams and
subscriptions, we now validate the events generated by
the actions under test conform to predicted schemas.
We define the schemas with help from the validators code
that is also sometimes used to validate incoming request
parameters for our views.

This sets up a scheme to validate complex data structures and
give specific error messages for improperly typed parameters.
