Subject: [PATCH/RFC/GSoC 09/17] rebase-common: implement cache_has_unstaged_changes()
Date: Sat, 12 Mar 2016 18:46:29 +0800 [thread overview]
Message-ID: <1457779597-6918-10-git-send-email-pyokagan@gmail.com> (raw)
In-Reply-To: <1457779597-6918-1-git-send-email-pyokagan@gmail.com>
In the upcoming git-rebase-to-C rewrite, it is a common operation to
check if the worktree has unstaged changes, so that it can complain that
the worktree is dirty.
builtin/pull.c already implements this function. Move it to
rebase-common.c so that it can be shared between all rebase backends and
git-pull.
