cr doesn't work on Python 3.13?

[ehmatthes]

I was trying out CodeRed for the first time, and getting inconsistent behavior between several projects I was deploying. I finally narrowed it down to cr working in 3.12 environments, and failing in 3.13 environments.

This is on macOS, using zsh, but I think this is an issue relating to the use of urlopen() in cr/api.py. In 3.13, urlopen() no longer accepts a cafile argument. I got it to work by modifying request_json() in api.py, but it's just a demo; I'm not sure the best place to put that change, or if I used the best approach.

Reproduction

Here's a 3.12 session that makes a cr check call against a fake project, returning the expected Error: No Webapp matches the given query. A 3.13 session with the same call generates an API error.

Demo fix

In the 3.13 venv, I made the following change in api.py and the cr check call worked.

def request_json(
    ...
) -> Tuple[int, dict]:
    """
    Makes an HTTP request and parses the JSON response.
    """
    ...
    # Open the request and read the response.


    import ssl
    context = ssl.SSLContext(ssl.PROTOCOL_TLS_CLIENT)
    context.load_verify_locations(cafile=certifi.where())
    try:
        r = urlopen(req, timeout=timeout, context=context)


        ...
    except HTTPError as err:
        ...

    return (code, d)

Thanks Eric! We haven't tested cr in 3.13, which was a bit of a miss because we did just add 3.13 support on CodeRed Cloud a few weeks go. Anecdotally most people seem to be using the binary in their day-to-day (myself included). Thanks for the fix, I'll get this merged in.
