Remove make from BuildRoot

Summary

This change will remove make from the default buildroot in Koji and mock.

Owner

Current status

  • Targeted release: Fedora 34
  • Last updated: 2020-10-27
  • FESCo issue: <will be assigned by the Wrangler>
  • Tracker bug: <will be assigned by the Wrangler>
  • Release notes tracker: <will be assigned by the Wrangler>

Detailed Description

Phase 1: Analysis

For this change, we will start by creating a list of all packages that have a build-time dependency on make. This will be done by analyzing spec files and also by rebuilding all packages in Fedora with make removed from the buildroot to see which packages fail to build. Once we have this list, we will remove packages that already have BuildRequires:make in their spec file, and this final list will be all the packages that need to be updated in Phase 2.

Phase 2: Package Updates

Once we have the list of packages that need to be updated, we will proceed with adding BuildRequires: make to all spec files that require it. This new BuildRequires will be added to the line after the last BuildRequires: in the spec file. Also, the release number for packages will *not* be incremented for this change.

The spec file updates will be automated and chagnes will be pushed directly to dist-git once they are ready.

Phase 3: Update Buildroot

Once package spec files have been updated, then we can proceed with removing make from the BuildRoot. This will be done by removing make from the build group in Koji and by remvoing make from the buildsys-build group in comps (fedora-comps).

Phase 4: Monitor Failures

Once all the changes are in place, we will continue to monitor koji builds to see if there are any failures related to this change. We expect that the analysis done in Phase 1 would give us the complete list of packages that need to be updated, but it is always possible that something will be missed.

Feedback

Benefit to Fedora

Fedora has approximately 22309 packages, based on my research [1], there are approximately 10414 packages that either use make explicitly or fail to build when make is removed form the buildroot. This means that there are around 11895 packages that don't need make. Removing make from the BuildRoot will reduce the network traffic, download times, and disk usage for these builds in Koji and also for users doing builds with mock.

Removing make (and its dependencies) will:

  • Reduce the BuildRoot download size by: 7.3 MB [2]:
    • make: 539k
    • gc: 104k
    • guile22: 6.6M
    • libtool-ltdl: 36k
  • Reduce the BuildRoot install size by; 46 MB [2]:
    • make: 1.6M
    • gc: 229k
    • guile22: 44M
    • libtool-ltdl: 71k
