From: Stefano Rivera Date: Thu, 8 Oct 2015 13:19:51 -0700 Subject: Do not use embedded copy of ssl.match_hostname, when possible The system python has the necessary features backported, since 2.7.8-7 (and 221a1f9155e2, releasing in 2.7.9, upstream). However, alternative python implementations don't, yet, and urllib3 is used by pip in virtualenvs. Forwarded: not-needed Last-Update: 2014-11-18 Patch-Name: 05_avoid-embedded-ssl-match-hostname.patch --- src/urllib3/packages/__init__.py | 10 ++++++++-- 1 file changed, 8 insertions(+), 2 deletions(-) diff --git a/src/urllib3/packages/__init__.py b/src/urllib3/packages/__init__.py index fce4caa..ffe70a4 100644 --- a/src/urllib3/packages/__init__.py +++ b/src/urllib3/packages/__init__.py @@ -1,5 +1,11 @@ from __future__ import absolute_import -from . import ssl_match_hostname - __all__ = ("ssl_match_hostname",) + +try: + # cPython >= 2.7.9 has ssl features backported from Python3 + from ssl import CertificateError + del CertificateError + import ssl as ssl_match_hostname +except ImportError: + from . import ssl_match_hostname
