let's imagine we have that case: python-foo is a python module that uses and needs features from python2.X. python-bar uses python-foo but can work with all 2.* python version.
Python-Versions will be: * >= 2.X for python-foo * all for python-bar how do we ensure that a user that has a python 2.Y installed, Y < X will not been able to install python-bar without also pulling python2.X ? Note that such a scheme can arise if a python-foo module decide to drop the support for a python release they consider ancient (like 2.3 nowadays). all the informations I got around for that problem were that it had to be manually tracked, which: * looks rather error prone ; * is computable since in that case, python-foo should not advertise its python2.Y support, but only >= 2.X. its Python-Version should be intesected avec the ones of its Depends, and only generate the relevant Provides. Reading the policy, it's unclear to me if arch:all package would have the python#.#-xxxx provides or if only arch:any will. if the former, then I fear computing the Depends: in the packages will become a real challenge and prevent bin-NMUS, not to mention uninstability problems, if the latter it will hide problems like the one above. Is there anything planned to address that ? -- ·O· Pierre Habouzit ··O [EMAIL PROTECTED] OOO http://www.madism.org
