The application decorated by the decorator will not trigger a Type Error, causing uvicorn to recognize it as a factory class

[vanker-x]

Hello everyone!

Please forgive me for not being very good at English first，the reason is that I need to do some operations (such as setting context variables) before and after the application is called, so I wrote a universal decorator to decorate WSGI, ASGI, RSGI applications, so I had to write the inner function as args, kwargs to accept different parameter. But it cause TypeError to be incorrectly thrown in lines 472-483 of uvicon/config.py, identifying it as a factory class

• my environment: Running uvicorn 0.24.0.post1 with CPython 3.9.8 on Darwin
• Here is the code I reproduced:

from functools import wraps


def wrong_wrapper(fn):  # wrong
    @wraps(fn)
    async def inner(*args, **kwargs):
        """
        The reason is that a TypeError was not raised when attempting to
        call in lines 472-483 of uvicon/config.py
        :param args:
        :param kwargs:
        :return:
        """
        return await fn(*args, **kwargs)

    return inner


def wrapper(fn):
    @wraps(fn)
    async def inner(scope, receive, send):
        """
        :param scope:
        :param receive:
        :param send:
        :return:
        """
        return await fn(scope, receive, send)

    return inner


@wrong_wrapper  # wrap this application
async def application(scope, receive, send):
    pass


if __name__ == '__main__':
    from uvicorn import run

    run(application)
