Add Python 3 support to Solum
It’s time to add Python 3 support to Solum by generalizing the usage of the six module, in addition to the Python 2 support.
The goal is to make Solum compatible with Python 3 at the end of the Liberty cycle.
For the rationale, the plan and work items, please see Nova Python 3 spec, since it's almost the same for Solum:
http://
Summary of the plan:
* Write a few bunch of patches to fix the most obvious Python 3 syntax issues (dict.iteritems, 123L, reraise an exception, etc.) to be able to load unit tests
* Find a subset of unit tests which pass on Python 3.4 and add a py34 target in tox.ini to run them.
* Add a non-voting py34 check job running tox -e py34
* When the py34 check job becomes stable enough, make it voting. At this point, it's no more possible to add regressions on the Python 3 in the tests executed by tox -e py34
* Fix remaining tests one by one, each time add it to the py34 target of tox.ini
