Thank you for filling out a Git bug report! Please answer the following questions to help us understand your issue. What did you do before the bug happened? (Steps to reproduce your issue) $ mkdir /tmp/git-diff-test; cd /tmp/git-diff-test $ git init Initialized empty Git repository in /tmp/git-diff-test/.git/ $ touch foo $ git add foo $ git commit -m "foo" [main (root-commit) f60d7bc] foo 1 file changed, 0 insertions(+), 0 deletions(-) create mode 100644 foo $ mv foo bar $ git status -s D foo ?? bar $ git add foo bar $ git status -s R foo -> bar $ git diff --quiet --cached; echo $? 0 $ git diff --quiet --cached --no-renames; echo $? 1 What did you expect to happen? (Expected behavior) Versions prior to commit d7b97b7185521e3b9364b3abc6553df2480da173 returned 1 for `git diff --quiet --cached`. What happened instead? (Actual behavior) It returned 0. What's different between what you expected and what actually happened? The status code. Anything else you want to add: This bug report originates from a PR I filed with Magit here: https://github.com/magit/magit/pull/5221 I thought this difference between using `--no-renames` and not made sense, so I thought the problem lied with Magit. However, like tarsius in that thread points out, this is a change that happened recently with git and it's not in the release notes. After finding the commit that introduces the change, I see the message mentions "The new options are off by default, keeping the old behavior." It really doesn't seem intentional, so here's a bug report. Also, the above difference with --no-renames also happens if I move my ~/.gitconfig elsewhere, so there's no use of external diff tools. I verified that with strace, too. Please review the rest of the bug report below. You can delete any lines you don't wish to share.
