Feedback

Benefit to Fedora

This change will not be visible to Fedora end-users, but it will provide some benefits to Fedora packagers:

  • Moving some of the brp scripts out of redhat-rpm-config and into c-cxx-rpm-macros means that they won't be run for packages that don't depend on clang or gcc. This will help speed up some builds.
  • This will help reduce the review burden of redhat-rpm-config maintainers who aren't interested in C/C++ changes.


Scope

  • Proposal owners:
 * Create new c-cxx-rpm-macros package and move the relevant content from redhat-rpm-config.
 * Test the changes.
  • Other developers: N/A
  • Policies and guidelines: N/A (not needed for this Change)
  • Trademark approval: N/A (not needed for this Change)
  • Alignment with Objectives:

Upgrade/compatibility impact

How To Test

These changes will be tested by doing test builds of a sampling of Fedora packages.

User Experience

Dependencies

Contingency Plan

  • Contingency mechanism: (What to do? Who will do it?) The proposal owners will revert the changes in redhat-rpm-config and removed the c-cxx-rpm-macros package
  • Contingency deadline: Beta Freeze
  • Blocks release? No
