No way to release pool connection when using decorator and aiohttp

[kivsiak]

When i use @cache decorator in my aiohttp application and close app using ctrl-C i got this message in output:

Task was destroyed but it is pending!

Not critical, but dirty. Is there any way to clear close all connection and courtines? In aiohttp cleanup handler?

Hi @kivsiak, yup its a known issue. There is manual way of doing this if you really need it.

Any function that you decorate will have an attribute called cache: https://github.com/argaen/aiocache/blob/master/aiocache/decorators.py#L50. In your cleanup handler, you can do `await my_decorated_function.close().

Hello @argaen, looks like i'm bad at decoration, usualy i use this way to add attrs: https://gist.github.com/kivsiak/9a2b5965ee3fd40c8c4b072e160a63cf

Here the gist of my way of using @cached decorator:

https://gist.github.com/kivsiak/b2fc47008f1cdc01bd4d08359ccfc2d8

cached_call after decoration have no _cache, cache, close() attributes.

You are right, with the current implementation the cache is not accessible through the decorated function.

By adding a wrapper.cache = self.cache in https://github.com/argaen/aiocache/blob/master/aiocache/decorators.py#L67 should be enough.

Do you want to provide MR for this? (should include tests + docs updated).

Next release this will be avaible as function.cache
