To determine if a repository is a worktree or not, we currently check for the existence of a "gitdir" file inside of the repository's gitdir. While this is sufficient for non-broken repositories, we have at least one case of a subtly broken repository where there exists a gitdir file inside of a gitmodule. This will cause us to misidentify the submodule as a worktree. While this is not really a fault of ours, we can do better here by observing that a repository can only ever be a worktree iff its common directory and dotgit directory are different. This allows us to make our check whether a repo is a worktree or not more strict by doing a simple string comparison of these two directories. This will also allow us to do the right thing in the above case of a broken repository, as for submodules these directories will be the same. At the same time, this allows us to skip the `stat` check for the "gitdir" file for most repositories. |
