How to combine with https://github.com/inyutin/aiohttp_retry

[foooooooooooooooobar]

Hey! Thanks for the library, I was wondering if it's possible to use the retry and cache libraries together?

[JWCook]

Good question! Yes, there would be a few different ways to combine these. This library subclasses ClientSession, and it looks like aiohttp_retry wraps a ClientSession object. So, the quick and ugly way would be to monkey-patch RetryClient's inner ClientSession:

import aiohttp_retry
import aiohttp_client_cache

aiohttp_retry.ClientSession = aiohttp_client_cache.CachedSession
client = aiohttp_retry.RetryClient(...)

Or replace it after initialization:

client = aiohttp_retry.RetryClient(...)
client._client = CachedSession(...)

That should give you both caching and retry features, but I haven't tested it yet.

A better and more pythonic solution, I believe, would be to refactor both CachedSession and RetryClient to be mixin classes, instead of a subclass and wrapper class, respectively. Then you could do something like this:

class CustomSession(RetryMixin, CacheMixin, ClientSession):
    """Session class with retry + caching features"""

That might be worthwhile, because there are other features I'd like to be able to combine with aiohttp_client_cache without making them tightly coupled.

Fyi, aiohttp_client_cache.CacheMixin has been added for this purpose.

Closing this issue for now; let me know if the above answers your question.
