2way-ssl and server hostname

[kelvinkwong]

Client Certificate

Client Certificate is not configured in XMLStream._create_secure_socket() for Python > 3.4

Please change line 473:
ctx.load_verify_locations(cafile=self.ca_certs)
to:

if self.ca_certs:
    ctx.load_verify_locations(cafile=self.ca_certs)
if self.certfile and self.keyfile:
    ctx.load_cert_chain(self.certfile, self.keyfile)

So it checks the certificates are not None, before committing it in connection.

Server Hostname

Also, Server hostname is required on my instance in XMLStream._create_secure_socket(). Not sure if everybody needs it. On line 523:
return ctx.wrap_socket(self.socket, do_handshake_on_connect=False)
To:
return ctx.wrap_socket(self.socket, do_handshake_on_connect=False, server_hostname=self._expected_server_name)
