Wiki - https://fedoraproject.org/wiki/Changes/ChangeToGitCore Discussion Thread - https://discussion.fedoraproject.org/t/f42-change-proposal-switch-to-git-core-self-contained/138975 This is a proposed Change for Fedora Linux. This document represents a proposed Change. As part of the Changes process, proposals are publicly announced in order to receive community feedback. This proposal will only be implemented if approved by the Fedora Engineering Steering Committee. = Switch to git-core = == Summary == Packages that only require `git` binary should depend on `git-core` and not on the `git` package. == Owner == * Name: [[User:Mikelo2| Mikel Olasagasti]] * Email: mikel at olasagasti.info == 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. In a fresh rawhide image `git-core` package installs 10 packages and requires 8 MiB, while `git` package requires 77 packages and 19 MiB. 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. Currently around 230 packages have `git` as `BuildRequires` and another 60 as `Requires`.

In November 2020 a [https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx/message/GS7GOUITUEASRELL7SKGLVJLGS3ZVJ45/ suggestion to switch to git-core] was discussed in the Development list. == Benefit to Fedora == For users it will reduce the amount of packages installed as transient dependency of the main package. For developers it should make builds a few seconds faster. Tests with podman on a local machine (i7-1270P) show 1 to 6 seconds less are required to install `git-core` vs `git`. == Scope == * Proposal owners: * Other developers: * Release engineering: [https://pagure.io/releng/issues #Releng issue number] * Policies and guidelines: N/A (not needed for this Change) * Trademark approval: N/A (not needed for this Change) * Alignment with the Fedora Strategy: == Upgrade/compatibility impact == == How To Test == * For those packages that have `git` as BuildRequire, testing the build can be automated using copr. Plan would be to fork the packages, switch to `git-core`, commit in the fork and build it in Copr. If builds fine open a PR. * For those packages that have `git` as Require, switch package to use `git-core` and test git related functionality. == User Experience == == Dependencies == None. == Contingency Plan == * Contingency mechanism: N/A * Contingency deadline: N/A * Blocks release? N/A == Documentation == N/A (not a System Wide Change) == Release Notes == -- Aoife Moloney Fedora Operations Architect Fedora Project Matrix: @amoloney:fedora.im IRC: amoloney -- _______________________________________________ devel-announce mailing list -- devel-announce@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-announce-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel-announce@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue -- _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
