testPythonOrg() of test_robotparser fails on validating python.org HTTPS certificate #72338
Comments
The "x86 Windows7 3.x" buildbot fails to validate python.org HTTPS certificate. The unit test uses the clear text HTTP URL, but http://www.python.org/robots.txt returns "301 Moved Permanently" with the new link: https://www.python.org/robots.txt Firefox sees the cert as valid on my Fedora 24. Firefox tells me that the cert organization (O) is "Python Software Foundation" and it was emitted by (CN) "DigiCert SHA2 Extended Validation Server CA", (O) "DigiCert Inc", (OU) "www.digicert.com". Does this buildbot lack DigitCert root CA? http://buildbot.python.org/all/builders/x86%20Windows7%203.x/builds/11636/steps/test/logs/stdio ====================================================================== Traceback (most recent call last):

A workaround is to catch the ssl.SSLError and skip the unit test... Another fix is to avoid completely network connection to the Internet and only uses the temporary HTTP server used by other unit tests. |
Note that I'm planning to rewrite the test to use pythontest.net. |
Here's a patch that uses pythontest.net. |
New changeset 83bca958adc9 by Berker Peksag in branch '3.6': New changeset 4bfd91a45c81 by Berker Peksag in branch 'default': |
test_robotparser is now green. I've opened bpo-28195 for test_huntrleaks_fd_leak. |
Thank you Berker! I'm quite sure that the issue is very old, like 1 year |
