[PATCH 0/4] Update use of python-enum34

[PATCH 0/4] Update use of python-enum34

[Leo Famulari]

Python-enum34 backports some features of Python 3.4 to earlier versions
of Python.

We now package python-3.4, so I think it's unnecessary to use it in our 
python-3 packages.

This patch series

1) Updates python-3.4 to the latest version that builds with our system.
2) Adds a python2-variant and uses it where necessary.
3) Removes python-enum34 where possible. I checked that all the affected
packages still build.
4) Removes python-setuptools as an input to python-enum34. It doesn't
seem to be necessary anymore.

I think we should keep the python3-variant around in case anyone is
using it "out of tree".

Your thoughts?

Leo Famulari (4):
  gnu: python-enum34: Update to 1.1.0.
  gnu: Add python2-enum34.
  gnu: Don't use python-enum34 when building with python-3.4.
  gnu: python-enum34: Remove python-setuptools from inputs.

I'd move the cryptography change to the next patch, it seems more in line

Good point, I did find the structure of the commits to be awkward.

I don't think so. python2-cryptography still builds, passes it's tests,
and seems to work in "downstream" applications.

I've noticed that the PyPi importer seems to unconditionally add
setuptools as an input (I didn't check the code yet). So, perhaps that
explains it's presence.

Or perhaps the version of python-2 we used at the time (2.7.6) did not
include some setuptools feature that has since been added to the
standard library.

Also, python-enum34 still builds with this change.

I built letsencrypt, which depends on python2-enum34 via
python2-cryptography, on this branch and successfully renewed my certs
with it.

If there are no other concerns about these patches, I'd like to apply
them soon.
