Drop Python 2.6, 3.2, and 3.3 from Travis CI #42
Description
Diagnostics for the Python 2.6 job:
DEPRECATION: Python 2.6 is no longer supported by the Python core team
pycparser requires Python '>=2.7, !=3.0.*, !=3.1.*, !=3.2.*, !=3.3.*' but the running Python is 2.6.9
The command "pip install coveralls" failed and exited with 1
Diagnostics for the Python 3.2 and 3.3 jobs:
$ tox
File "/home/travis/virtualenv/python3.3.6/lib/python3.3/site-packages/pkg_resources/__init__.py", line 90, in <module>
raise RuntimeError("Python 3.4 or later is required")
RuntimeError: Python 3.4 or later is required
In the first case, coveralls cannot be installed anymore (because of a dependency), while in the last two cases, tox fails (because setuptools has dropped support for Python 3.3 since v40.0.0). It might be possible to get some of the job running with workarounds (e.g., by disabling coveralls for py2.6, or by downgrading setuptools for py3.2 and py3.3), but they are quite old variants unsupported by either the core Python team or by a quite core Python package, so they may not be worth the efforts.
I'd be willing to submit a PR to drop these if you'd agree.
