[ovirt-devel] Python 3 vdsm RPM packages

Hi, On yesterday's vdsm weekly call, we were discussing the need of making Python 3 vdsm RPM packages. Some facts: - it doesn't make a lot sense to spend much time on trying to package everything - it's completely impossible i.e. to run vdsm without having 'sanlock' module - our current vdsm.spec file is crap Two non-exclusive propositions were raised: - let's try to make a quick-and-dirty patch, that will completely overwrite the existing 'vdsm.spec' (effectively making it Python 3-only) for testing purposes, and maintain it for a while - in the meantime, let's write a completely new, clean and beautiful spec file in an package-by-package, incremental manner, (also Python 3-only) that would eventually substitute the original one The quick-and-dirty spec file would be completely unsupported by CI. The new one would get a proper CI sub-stage in 'build-artifacts' stage. The steps needed to be done are: - prepare autotools/Makefiles to differentiate Python 2/Python 3 RPM builds - prepare the new spec file (for now including only 'vdsm-common' package) - split 'build-artifacts' stage into 'build-py27' and 'build-py36' sub-stages (the latter currently running on fc28 only) The only package we can start with, when making the new spec file, is 'vdsm-common', as it doesn't depend on anything else (or at least I hope so...). There were also propositions about how to change the new spec file in regard to the old one (like making 'vdsm' package a meta-package). This is a good time for these propositions to be raised, reviewed and documented (something like this maybe? https://docs.google.com/document/d/13EXN1Iwq-OPoc2A5Y3PJBpOiNC10ugx6eCE72...), so we can align the new spec file as we build it. I can lay the groundwork by doing the autotools/Makefiles and 'build-artifacts' splitting. Gal Zaidman agreed on starting to work on the new spec file. Milan mentioned, that he had something like the quick-and-dirty patch, maybe he can share it with us. Questions, comments are welcome. Regards, Marcin
