The `p2000` tests demonstrate a ~96% execution time reduction for 'git rm' using a sparse index. Test before after ------------------------------------------------------------- 2000.74: git rm -f f2/f4/a (full-v3) 0.66 0.88 +33.0% 2000.75: git rm -f f2/f4/a (full-v4) 0.67 0.75 +12.0% 2000.76: git rm -f f2/f4/a (sparse-v3) 1.99 0.08 -96.0% 2000.77: git rm -f f2/f4/a (sparse-v4) 2.06 0.07 -96.6% Also, normalize a behavioral difference of `git-rm` under sparse-index. See related discussion [1]. `git-rm` a sparse-directory entry within a sparse-index enabled repo behaves differently from a sparse directory within a sparse-checkout enabled repo. For example, in a sparse-index repo, where 'folder1' is a sparse-directory entry, `git rm -r --sparse folder1` provides this: rm 'folder1/' Whereas in a sparse-checkout repo *without* sparse-index, doing so provides this: rm 'folder1/0/0/0' rm 'folder1/0/1' rm 'folder1/a' Because `git rm` a sparse-directory entry does not need to expand the index, therefore we should accept the current behavior, which is faster than "expand the sparse-directory entry to match the sparse-checkout situation". Modify a previous test so such difference is not considered as an error.
