Projektgeschichte

Eric S. Raymond launched reposurgeon in October 2010 and published version 0.1 on 1 November 2010. Its original motivation was cleaning artifacts produced by repository conversions. It grew into an interactive and scriptable history editor plus a suite containing repocutter, repomapper, repotool, and conversion workflows.

The implementation supports fast-export and fast-import streams as a common interchange model and also uses extractors for systems without suitable exporters. This enables both surgical history editing and conversions spanning centralized and distributed version-control systems.

Adoptionsgeschichte

Reposurgeon has been used in conversions of historically important repositories, including Emacs, Blender, NUT, Battle for Wesnoth, groff, and GCC. The GCC conversion handled roughly 280,000 Subversion commits and cut over in January 2020.

Wie es verwendet wird

Operators import a repository or history stream, inspect its event graph, apply scripted or interactive edits, and write a new history or repository. The tool deliberately writes results separately rather than modifying or deleting the source repository.

Warum Paket-Nerds sich dafür interessieren

Repository migrations preserve the provenance on which source packages depend. Reposurgeon matters to package historians because it can recover, translate, and repair authorship, branches, tags, and ancient RCS/CVS/Subversion strata instead of merely copying snapshots into Git.
