"TypeError: RequestInfo.__new__() missing 1 required positional argument: 'real_url'" after upgrading aiohttp to 3.11.0.

[cdessez]

aiohttp just released v3.11.0.

Trying to use aioresponses together with aiohttp==3.11.0 leads to the following failure:

        )
E       TypeError: RequestInfo.__new__() missing 1 required positional argument: 'real_url'

This can be reproduced with the following minimal reproducer:

import aiohttp
from aioresponses import aioresponses
import pytest


@pytest.mark.asyncio()
async def test_aiohttp_3_11_0():
    with aioresponses() as aiohttp_mock:
        url = "http://example.com"
        aiohttp_mock.get(url, status=200, body="Yo!")
        async with aiohttp.ClientSession() as session:
            async with session.get(url) as response:
                body = await response.text()
                print(body)

This test leads to the above failure on aiohttp==3.11.0, but passes on aiohttp==3.10.11.

I raised this with aiohttp: aio-libs/aiohttp#9866

[bdraco]

Fix is here #262

[cdessez]

This is now resolved. Fixed by both:

• Fix compat with aiohttp 3.11.0+ #262 being merged
• aiohttp releasing 3.11.1 with Make creating RequestInfo backwards compatible with 3.10 aio-libs/aiohttp#9873
