SSLContext infinite recursion in Python 3.6

[juokaz]

The issue is this method in python/ssl.py.

    @options.setter
    def options(self, value):
        super(SSLContext, SSLContext).options.__set__(self, value)

It fails when using for example requests library:

I believe you're using gevent 1.1, yes? Please use gevent 1.2a1 or newer on Python 3.6.

I tried running on 1.2a1 and it worked. My bad, thank you @jamadden!

Now that python3.6 is released, should we re-open this ticket until gevent >1.2 becomes default pip install? As it stands the "stable" 3.6 standard library with a default setup is not usable with https urls.

[jamadden]

gevent 1.2 was released the same day as 3.6.

Ah thanks @jamadden, it looks like I mistakenly thought pip install --upgrade requests would also bump gevent to the newer required version. Working for me now after pip install --upgrade gevent.
