Windows 10 support.

Windows 10 support is broken as of python 3.8 now thanks to the event loop policy changing. Any plans on fixing this?

@creator1372 Thanks for the report.

Unfortunately, I don’t have a Windows machine at all. So I can’t even see the error message or the problematic behaviour without a report.

I’d be interested in improving windows support if someone would help with these things and testing.

well, it's actually a pretty easy fix. The new event loop in python 3.7 is ProactorEventLoop which doesn't support loop.add_reader and loop.remove_reader. Fixing it should be as easy as adding this at the top of all the files in the project.

import os

if os.name == "nt":
    asyncio.set_event_loop_policy(asyncio.WindowsSelectorEventLoopPolicy())

@creator1372 This is something users should do then.

However, if the Proactor event loop can, with stock asyncio, do TLS, then this should be fixed. As I don’t have the systems required to develop and test it, it’s rather unlikely to happen.

I’ll leave this open so that others can find the workaround.

(Alternatively, someone should check if the stock asyncio TLS support can by now do all the things aioopenssl can do, in which case this package can simply be retired.)
