DNF 2.0

Summary

DNF rebase to version 2.0.

Owner

Current status

  • Targeted release: Fedora 26
  • Last updated: 2016-09-15
  • Tracker bug: <will be assigned by the Wrangler>

Detailed Description

DNF-2.0 is the next upcoming major version of DNF package manager. Unfortunately, it brings some incompatibilities with previous version of DNF (DNF-1) which were either needed to preserve compatibility with YUM CLI or where bigger redesigns were needed. A list of identified incompatible changes can be found here[1].

Benefit to Fedora

New major version of DNF brings many new features and bug fixes. Moreover, the support period of older versions is reaching its end.

Scope

  • Proposal owners:
    • complete release notes 
    • deliver DNF-2.0 stack to Rawhide
  • Other developers:
    • Owners of 3rd party DNF plugins or components depending on DNF should check and adjust their packages otherwise they may not work with DNF-2.0.
  • Release engineering:
    • All release engineering tools that depends on DNF should be tested against DNF-2.0.

Upgrade/compatibility impact

Enduser compatibility should be preserved as much as possible. We do not expect any manual user intervention.

How To Test

  • early adopters are welcomed to use this COPR repo for testing
  • testing scenarios:
    • anaconda installation
    •  upgrade from previous Fedora version
    • core functionality: install, upgrade, remove, repoquery
    •  dnf-plugins: copr, system-upgrade, download
    • third party software: mock, yumex


User Experience

N/A (unaffected)

Dependencies

N/A (not a System Wide Change)

Contingency Plan

  • Contingency mechanism:
    • revert to DNF-1.1.x (epoch bump)
    • revert to DNF-plugins-core-0.1.x (epoch bump)
    • revert to DNF-plugins-extras-0.0.x (epoch bump)
    • consequent rollback of already ported components
  • Contingency deadline: F26 Alpha Freeze
  • Blocks release? Yes
