aiohttp 3.10 appears not to work with aiodocker

[Julian]

Long story short

aiohttp==3.10.0 (released mid-July) appears to break aiodocker entirely here.

Any use of the library produces an exception complaining about the use of unix://localhost, which I see aiodocker uses as a dummy URI.

• Expected behaviour: No error / same behavior as with aiohttp 3.9
• Actual behaviour: The following exception:

How to reproduce

Run e.g.:

rm -rf venv && uv venv venv && uv pip install --python venv/bin/python aiodocker 'aiohttp>=3.10' && venv/bin/python -c '                                                                                                                                                   julian@Airm ●
import asyncio

from aiodocker import Docker

async def main():
    async with Docker() as docker:
        print(await docker.version())

asyncio.run(main())

Your environment

macOS with a remote docker host set to:

⊙  echo $DOCKER_HOST                                                                                                                                                                                                                                                          julian@Airm ●

c.f. #833, though that seems no longer accurate (I was using 3.9 here myself for awhile so I think 3.9 seemed fine?) -- more relevant seems to be #885 where it seems aiohttp 3.10 breaks aiodocker's own suite.

I haven't looked into what the fix looks like (one would hope it's tiny?) but perhaps if it isn't completely trivial, simply pinning away from 3.10 is a temporary solution.
