[Python-modules-team] Bug#873965: aiohttp: C extension is broken

[Matthias Urlichs]

Package: python3-aiohttp
Version: 2.2.3-1
Severity: important
File: aiohttp

I was unable to get the supplied compiled parser to work.

$ /usr/bin/py.test-3 -sxv tests/

tests/test_client_functional.py::test_keepalive_two_requests_success[pyloop] Error handling request
Traceback (most recent call last):

    return URL(schema, host, port, path, query, fragment, userinfo)
TypeError: __new__() takes from 1 to 2 positional arguments but 8 were given

A test run with either PYTHONPATH=. or AIOHTTP_NO_EXTENSIONS=1 worked.
This applies to both Python 3.5 and 3.6.
