Subject: [PATCH v2 10/11] worktree move: refuse to move worktrees with submodules
Date: Mon, 28 Nov 2016 16:43:18 +0700 [thread overview]
Message-ID: <20161128094319.16176-11-pclouds@gmail.com> (raw)
In-Reply-To: <20161128094319.16176-1-pclouds@gmail.com>
Submodules contains .git files with relative paths. After a worktree
move, these files need to be updated or they may point to nowhere.
This is a bandage patch to make sure "worktree move" don't break
people's worktrees by accident. When .git file update code is in
place, this validate_no_submodules() could be removed.
