The first patch add flake8 tests and pylint --py3k to RPM build. The second patch fixes a couple of flake8 violations that have accumulated in the past month. I'm still having a problem with sphinx autodocs. It can't build documentation for pki.crypto. It looks like autodocs doesn't do relative imports correctly and picks up pki/nss.py as nss. SphinxWarning: /home/heimes/redhat/pki/base/common/python/pki.rst:39: WARNING: autodoc: failed to import module u'pki.crypto'; the following exception was raised: Traceback (most recent call last): File "/home/heimes/redhat/pki/.tox/docs/lib/python2.7/site-packages/sphinx/ext/autodoc.py", line 385, in import_object __import__(self.modname) File "/home/heimes/redhat/pki/.tox/docs/lib/python2.7/site-packages/pki/crypto.py", line 26, in <module> import nss.nss as nss ImportError: No module named nss Christian
