Description: Disallow control chars in http URLs in urllib2.urlopen. This addresses a potential security problem for applications that do not sanity check their URLs where http request headers could be injected. Disable https related urllib tests on a build without ssl (GH-13032) These tests require an SSL enabled build. Skip these tests when python is built without SSL to fix test failures. Use httplib.InvalidURL instead of ValueError as the new error case's exception. (GH-13044) Backport Co-Authored-By: Miro Hrončok miro@hroncok.cz (cherry picked from commit 7e200e0) Notes on backport to Python 2.7: test_urllib tests urllib.urlopen() which quotes the URL and so is not vulerable to HTTP Header Injection. Add tests to test_urllib2 on urllib2.urlopen(). Reject non-ASCII characters: range 0x80-0xff. https://bugs.python.org/issue30458
