Eliminate the python- prefix from the Python 2 package names and /usr/bin/python from shebangs

Summary

With Python 2 approaching it's EOL, we are trying to prepare Fedora for a transition to Python 3 as default, so that python without a version number means Python 3. This Fedora change is the first step on the way to achieving this.

Owner

Current status

  • Targeted release: Fedora 28
  • Last updated: 2017-12-18
  • Tracker bug: <will be assigned by the Wrangler>

Detailed Description

Finalizing Fedora's Switch to Python 3 document provides detailed information on the matter. This Fedora change covers only Phase 1 of the transition steps, and aims to clean up Fedora packages in accordance with recent changes to Python packaging guidelines regarding the usage of python without a version number in package names, requirements, shebangs, etc. The clean up covers:

  • Renaming Python 2 binary RPMs from python-foo to python2-foo

This is already partially done by applying automated patches as announced in Mass package change (python2- binary package renaming). The packages which still need to be fixed are tracked in PortingDB.

  • Fixing ambiguous Python 2 dependency declarations, i.e using python2-foo instead of python-foo in requirements

We have started opening automatic Pull Requests with patches as announced in Mass Pull Request filing for ambiguous Python 2 requirements. The packages which will be targeted are tracked in PortingDB.

  • Ensuring that /usr/bin/python or /usr/bin/env python shebangs are replaced with either /usr/bin/python2 or /usr/bin/python3


Each of the above steps conforms to the Python packaging guidelines and was approved by FPC. The work on the change is already in progress and will be tracked by this Fedora change.
