Subject: [PATCH 1/6] worktree.c: add validate_worktree()
Date: Sun, 8 Jan 2017 16:39:58 +0700 [thread overview]
Message-ID: <20170108094003.637-2-pclouds@gmail.com> (raw)
In-Reply-To: <20170108094003.637-1-pclouds@gmail.com>
This function is later used by "worktree move" and "worktree remove"
to ensure that we have a good connection between the repository and
the worktree. For example, if a worktree is moved manually, the
worktree location recorded in $GIT_DIR/worktrees/.../gitdir is
incorrect and we should not move that one.
