Subject: BUG in git diff-index
Date: Thu, 31 Mar 2016 12:39:23 +0000 (UTC) [thread overview]
Message-ID: <loom.20160331T143733-916@post.gmane.org> (raw)
Following transcript illustrates what I believe to be a bug in git diff-
index. The session used a git built from latest source, located in
/tmp/git/git.
1. New repo, create empty file A, commit changes.
2. touch A
3. git diff-index reports A has changed, and reports bogus destination
SHA
4. This is stable behavior until next step
5. git diff correctly reports no changes
6. git diff-index now also reports nothing
My understanding is that git diff-index should care only about content
and file mode, not modification time.
