[Python-apps-team] Bug#683133: robust cython version comparisons Was: Bug#683133: xpra: robustify ...

[Yaroslav Halchenko]

Hi Antoine,

NB CCing bug #683130 against bzr with similar issue

sorry for lacking details:

$> python -c 'from Cython.Compiler.Version import version; print(version)'
0.17.beta1

alternatively to manual parsing and ignoring errors you might like to just use

$> python -c 'from distutils.version import LooseVersion as LV; print LV("0.17") < LV("0.17.beta1")' 
True

it is ignorant about suffixes like .beta (thus above result) but is robust
enough in general and should work for your case I guess with min 0.14 version.

NB  StrictVersion is aware of some suffixes but would fail if such as
beta occurs so less advisable to use.
