Infrastructure » Python GMN

As of Python 2.7.9, which was released late 2014, full SSL support is now enabled (https://www.python.org/dev/peps/pep-0476/). This change in the Python SSL module will cause an SSL exception to occur when connecting to any server using a self-signed certificate and or a certificate that is signed by a non-recognized CA -- this change directly affects a "local" installation of GMN if using the local CA (http://pythonhosted.org/dataone.generic_member_node/setup-local-authn-ca.html). This problem manifests in any Python 2.7.9 client using the SSL module that attempts an SSL connection to a "local" install of GMN. There is, however, a "highly discouraged" global setting that reverts the SSL module to its previous behavior:

import ssl

ssl._create_default_https_context = ssl._create_unverified_context

Note: testing with a server that uses a certificate signed with a recognizable CA averts any exception.
