Switch to git-core

Summary

Packages that only require git binary should depend on git-core and not on the git package.

Current status

  • Targeted release: Fedora Linux 42
  • Last updated: 2024-11-18
  • [Announced]

Detailed Description

Many package have either requirement or build requirement for the git binary. The git package is complex and is divided in mulitple subpackages. The subpackage that contains the git binary, that is enough for most of the use cases, is part of the git-core subpackage.

Currently around 230 packages have git as BuildRequires and another 60 as Requires. Verified using latest snapshot available in https://src.fedoraproject.org/lookaside/rpm-specs-latest.tar.xz with grep -E '^Requires:\s*git$' *.spec |wc -l and grep -E '^BuildRequires:\s*git$' *.spec |wc -l commands.

In a fresh rawhide image git-core installs 10 packages and requires 8 MiB, while git requires 77 packages and 19 MiB.

Transaction Summary:
 Installing:        77 packages

Total size of inbound packages is 19 MiB. Need to download 19 MiB.
After this operation, 75 MiB extra will be used (install 75 MiB, remove 0 B).

The proposed change would be to open Pull Requests against each package to switch to git-core and, when possible, test it before the PR is accepted.



Feedback

This change has been already proposed for packit in PR1307, that was accepted upstream and will be part of F42.

Benefit to Fedora

For users it will reduce the amount of packages installed as transied dependency of the main package.

For developers it should make builds a few seconds faster.
