Differences from Git

In some instances, the functionality of libgit2 deviates slightly from Git. This can be because of technical limitations when developing a library, licensing limitations when converting functionality from Git to libgit2, or various other reasons.

Repository and Workdir Path Reporting

When asking Git for the absolute path of a repository via git rev-parse --absolute-git-dir, it will output the path to the ".git" folder without a trailing slash. In contrast to that, the call git_repository_path(repo) will return the path with a trailing slash:

git rev-parse --absolute-git-dir -> /home/user/projects/libgit2/.git
git_repository_path(repo) -> /home/user/projects/libgit2/.git/

The same difference exists when listing worktrees:

git worktree list -> /home/user/projects/libgit2
git_repository_workdir(repo) -> /home/user/projects/libgit2/
