[issue19494] urllib2.HTTPBasicAuthHandler (or urllib.request.HTTPBasicAuthHandler) doesn't work with GitHub API v3 and similar

I am trying to work on fixing issue 19494 (HTTPBasicAuthHandler doesn't work with Github and other websites which require prior Authorization header in the first request).

I have created this testing script calling GitHub v3 API using new “authentication handlers” (they are subclasses of HTTPSHandler, not HTTPBasicAuthHandler) and hoped that when I manage to make this script working, I could rewrite it into patch against cpython code.

However, when I run this script I get this error (using python3-3.3.2-8.el7.x86_64)

Could anybody suggest what I am doing wrong? I seem to have problem of working in between two superclasses (HTTPHandler and AbstractBasicAuthHandler). I guess I need to somehow include into opener original HTTPBasicAuthHandler (for error handlers). Any ideas how to do it?
