Summary

Distinguish all Python 2 and Python 3 packages with a new convention:

  • Python 2 packages rename to "python2-PKGNAME" Keep Python 2 packages as they are (so use the standard prefix "python-" or without additional string eg. "waf"). Consider renaming for {MgaX, X>3}
  • Python 3 packages rename to "python3-PKGNAME" or "PKGNAME-python3"

Import missing libraries for Python 3.

Detailed Description

Base our specs with Python packages on Fedora, and make them produce Python 2 and Python 3 packages. Distinguish Py2 and Py3 environment, make order with virtual packages (provides) and dependencies (against simply python). Promote Py2 for Mga3, make the global switch in Mga to Py3 simpler. External References: Fedora

All corresponding packages for Python 2 and Python 3 will be packaged in a single .spec.

Why it would be good for Mageia to include it

Py3 support in Mageia is very limited (there is short library base), there are dependency potential and hidden problems with providing Py packages without distinguishing Py2 <=> Py3.

Test case

Software / Packages Dependencies

Python 3 packages will be mostly outside the rest of the software, so there shouldn't be any problems with the core system.

What could disrupt development of this new feature

Just human resource time and work that has to be done.

Planning

  1. Prepare python3-* packages.
  2. Prepare .macros - all Python3 software is going to have "python3-" or "python3_" prefix.
  3. Double check dependencies, provides, requirements and link everything against Python 2.
  4. Answer reports in Bugzilla.

Contingency

Continue works in Mga4.
