From 9d4e28ead5bf133d014dfc9e9345f6bf083eefea Mon Sep 17 00:00:00 2001 From: Jeff King Date: Tue, 6 Dec 2016 15:25:21 -0500 Subject: stash: prefer plumbing over git-diff When creating a stash, we need to look at the diff between the working tree and HEAD, and do so using the git-diff porcelain. Because git-diff enables porcelain config like renames by default, this causes at least one problem. The --name-only format will not mention the source side of a rename, meaning we will fail to stash a deletion that is part of a rename. We could fix that case by passing --no-renames, but this is a symptom of a larger problem. We should be using the diff-index plumbing here, which does not have renames enabled by default, and also does not respect any potentially confusing config options.
