Scope

• Other developers: Pierre-Yves Chibon (pingou) for some of the Pagure enhancements

• Release engineering: #6775

• • List of deliverables: N/A (not a System Wide Change)

• 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.
