Scaling Git’s garbage collection (GitHub blog)
[Posted September 14, 2022 by corbet]
The GitHub blog has a detailed look at garbage collection in Git and the work that has been done to make it faster.
To solve this problem, we turned to a long-discussed idea on the Git mailing list: cruft packs. The idea is simple: store an auxiliary list of mtime data alongside a pack containing just unreachable objects. To garbage collect a repository, Git places the unreachable objects in a pack. That pack is designated as a “cruft pack” because Git also writes the mtime data corresponding to each object in a separate file alongside that pack. This makes it possible to update the mtime of a single unreachable object without changing the mtimes of any other unreachable object.
