Another thing to look is for .so files corresponding > to several python versions in /usr/lib/python-support/*/python2.? or > /usr/lib/python2.?/site-packages. like said, there is one information that is not in the Build-Depends, and that XS-P-V and pyversion provides, that is if the next transition move is supported by that package, if : * a new python runtime is added ; * the default python changes. for that default going from 2.3 -> 2.4 steve had to know wether packages that needed binNMU (because Depending upon python (<< 2.4) e.g.) did supported python 2.4. For that, you need XS-P-V or debian/pyversions. that does not ensure that the package is binNMUable of course, but that's almost a python policy violation and is RC, so we can assume it won't happen, or that we want to spot it anyway. Here, the fact that the packager depend on python-all-dev is not sufficient. The same apply if you add a new python runtime, you want to binNMU packages that supports it, and not the ones that does not. all the rest is way better found in the Depends rather than in other custom fields, we do agree here. > > So my proposal is to make XS-P-V mandatory when there is an upper > > bound. > > Beware of one thing: having both XS-P-V and pyversions is the worst > case we can have, as the maintainer has to ensure they contain the > same information. in that case we must only have XS-P-V obviously ! I think dh_pysupport already barf in that case IIRC, if it does not it should. Note that like said, the number of packages with a valid upper bound is very small (something like 10 packages over the 745 that build-depend on any python in unstable/main). -- ·O· Pierre Habouzit ··O madcoder@debian.org OOO http://www.madism.org
