Subject: [PATCH v4 11/13] submodule--helper: remove ensure-core-worktree
Date: Fri,  4 Mar 2022 16:13:59 -0800	[thread overview]
Message-ID: <20220305001401.20888-12-chooglen@google.com> (raw)
In-Reply-To: <20220305001401.20888-1-chooglen@google.com>

Move the logic of "git submodule--helper ensure-core-worktree" into
run-update-procedure, and since this makes the ensure-core-worktree
command obsolete, remove it.

As a result, the order of two operations in git-submodule.sh is
reversed: 'set the value of core.worktree' now happens after the call to
"git submodule--helper relative-path". This is safe - "relative-path"
does not depend on the value of core.worktree.
