Question: Why do not use latest aiohttp?

[item4]

latest aiohttp is 2.3.2 but discord.py depend on aiohttp>=1.0.0,<1.1.0

Why use old version of aiohttp? How can I use latest one?

[khazhyk]

fwiw, I've been using aiohttp 2.2.5 without issues

I have also been using 2.2.5 without issue.

aiohttp had a tendency to memory leak or have other issues for a while (such as the flip-flop on ClientSession being inside a coroutine), hence why the lib pinned it to a stable version that doesn't do it.

[Rapptz]

Pinning dependencies isn't exactly strange.

It's the recommended practice even.

Along with what was said above, v1.0 -> v2.0 is a breaking change so it requires review before pushed through. That upgrade path had e.g. memory leaks and the like so it wasn't done. It's probably fine now but I'm not gonna unpin it.

aiohttp is now 3.3.2.

The latest version of aiohttp is used in the rewrite branch. The async branch no longer receives updates and will not have the requirements unpinned as the issues with the latest will not be fixed. If the latest aiohttp is a requirement, the rewrite branch is fully useable and still maintained. For more information on the rewrite branch, join the official server.

@Rapptz v1.0 aiohttp used back in python2. As in python3 introduced new importing API therefore legacy libraries rise a warning:

C:\Program Files\Python36\lib\importlib\_bootstrap.py:219: ImportWarning: can't resolve package from __spec__ or __package__, falling back on __name__ and __path__

Please make discord.py support latest aiohttp, let it use python3 features and help developers get rid of warnings.

Please don't necrobump issues.
aiohttp does not support Python 2 and never has. This warning comes from the fact that old versions of Cython do not include complete package data by default. You could fix this by either disabling the speedups or compiling aiohttp for yourself, but as the async branch won't be maintained for much longer, it is a better idea to just pivot to using rewrite instead.

Consider joining the discord.py Discord server if you want to learn more about upgrading to rewrite.
