Surprisingly, git doesn't track renames (seriously, there's no metadata in the .git directory that tells you when a file was moved). It merely uses heuristics and a similarity index to guess when a rename exists. There are ways to tighten the similarity index (git diff -M90% instead of git diff -M), as well as disable similarity checking altogether (git diff -l1, and various settings in git config). -- Eric Blake ebl...@redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org
