Martin von Zweigbergk 1cc271441f gc: implement basic GC for Git backend ... This adds an initial `jj util gc` command, which simply calls `git gc` when using the Git backend. That should already be useful in non-colocated repos because it's not obvious how to GC (repack) such repos. In my own jj repo, it shrunk `.jj/repo/store/` from 2.4 GiB to 780 MiB, and `jj log --ignore-working-copy` was sped up from 157 ms to 86 ms. I haven't added any tests because the functionality depends on having `git` binary on the PATH, which we don't yet depend on anywhere else. I think we'll still be able to test much of the future parts of garbage collection without a `git` binary because the interesting parts are about manipulating the Git repo before calling `git gc` on it.		2023-12-03 07:40:12 -08:00
