Subject: [PATCH 03/10] submodule add: support multiple worktrees
Date: Wed, 16 Jan 2019 17:31:52 +0700 [thread overview]
Message-ID: <20190116103159.9305-4-pclouds@gmail.com> (raw)
In-Reply-To: <20190116103159.9305-1-pclouds@gmail.com>
The entire submodule section in the superproject will be per-worktree
and written to $GIT_DIR/config.worktree.
The behavior when you only have one worktree (and not enabled
extensions.worktreeConfig) is the same as before, everything is still
written in $GIT_DIR/config
'submodule-helper config --check-writable' also checks if it's
supported worktree configuration.
