Subject: [PATCH v2 1/2] dir: consider worktree config in path recursion
Date: Tue, 10 May 2022 17:15:26 +0000 [thread overview]
Message-ID: <20220510171527.25778-2-ggossdev@gmail.com> (raw)
In-Reply-To: <20220510171527.25778-1-ggossdev@gmail.com>
Since 8d92fb2927 (dir: replace exponential algorithm with a linear one,
2020-04-01) the following no longer works:
1) Initialize a repository.
2) Set the `core.worktree` location to a parent directory of the
default worktree.
3) Add a file located in the default worktree location to the index
(i.e. anywhere in the immediate parent directory of the gitdir).
This commit adds a check to determine whether a nested repository that
is encountered in recursing a path is actually `the_repository`. If so,
simply treat the directory as if it doesn't contain a nested repository.
Prior to this commit, the `add` operation was silently ignored.
