Issue python#25940: Use self-signed.pythontest.net in SSL tests
This is instead of svn.python.org, whose certificate recently expired, and whose new certificate uses a different root certificate. The certificate used at the pythontest server was modifed to set the "basic constraints" CA flag. This flag seems to be required for test_get_ca_certs_ capath() to work (in Python 3.4+). Added the new self-signed certificate to capath with the following commands: cp Lib/test/{selfsigned_pythontestdotnet.pem,capath/} c_rehash -v Lib/test/capath/ c_rehash -v -old Lib/test/capath/ # Note the generated file names cp Lib/test/capath/{selfsigned_pythontestdotnet.pem,0e4015b9.0} mv Lib/test/capath/{selfsigned_pythontestdotnet.pem,ce7b8643.0} The new server responds with "No route to host" when connecting to port 444.
