Subject: [PATCH 03/11] repository.c: replace hold_locked_index() with repo_hold_locked_index()
Date: Thu, 24 Jan 2019 15:29:04 +0700
Message-ID: <20190124082912.24401-4-pclouds@gmail.com> (raw)
In-Reply-To: <20190124082912.24401-1-pclouds@gmail.com>

hold_locked_index() assumes the index path at $GIT_DIR/index. This is
not good for places that take an arbitrary index_state instead of
the_index, which is basically everywhere except builtin/.

Replace it with repo_hold_locked_index(). hold_locked_index() remains
as a wrapper around repo_hold_locked_index() to reduce changes in builtin/
