Benefit to Fedora

See the “Background on PkgDB” and “Why Make This Change?” sections in the Arbitrary Branching Focus document linked above.

Scope

  • Proposal owners: We will do all of the work listed in the linked document.
  • Other developers:
    • We're relying on the infra team to get Pagure on top of dist-git.
    • We're relying on releng to find any holes in our work plan and to help us make decisions on how to solve bugs.
    • No direct work should be required from the general packaging group to support this Change.
  • Release engineering: #6775
  • Policies and guidelines: Packaging guidelines would change and would be updated after the changes are implemented in staging.
  • Trademark approval: N/A (not needed for this Change)

Upgrade/compatibility impact

Not backwards compatible but not significantly difficult to roll back because all changes will be done in Ansible.

How To Test

  • Request new packages
  • Request new branches with non-standard names (i.e. not f25, f26, etc.) and build with them
  • Request new branches for standard names that are still supported (i.e. f25, f26, epel6, epel7) and build with them
  • Retire a package
  • Orphan a package

User Experience

See the “How To Make This Change?” section in the Arbitrary Branching Focus document linked above.

Dependencies

  • Pagure over dist-git will need to be updated in staging
  • Pagure over dist-git will need to be deployed in production

Contingency Plan

  • Contingency mechanism: Re-enable PkgDB and roll back our script changes in Ansible
  • Contingency deadline: N/A
  • Blocks release? Yes, it blocks Fedora 27 Modularity. They will be filing a Change document in the coming months to describe the F27 structure
  • Blocks product? Fedora 27

Documentation

Documentation on new processes would be provided at a later date if there is approval on this Change Proposal.
