If a file is different between the working tree copy, the index, and the HEAD, then we do not allow it to be deleted without --force. However, this is overly tight in the face of "git add --intent-to-add": $ git add --intent-to-add file $ : oops, I don't actually want to stage that yet $ git rm --cached file error: 'empty' has staged content different from both the file and the HEAD (use -f to force removal) $ git rm -f --cached file Unfortunately, there is currently no way to distinguish between an empty file that has been added and an "intent to add" file. The ideal behavior would be to disallow the former while allowing the latter. This patch loosens the safety valve to allow the deletion only if we are deleting the cached entry and the cached content is empty. This covers the intent-to-add situation, and assumes there is little harm in not protecting users who have legitimately added an empty file. In many cases, the file will still be empty, in which case the safety valve does not trigger anyway (since the content remains untouched in the working tree). Otherwise, we do remove the fact that no content was staged, but given that the content is by definition empty, it is not terribly difficult for a user to recreate it. However, we still document the desired behavior in the form of two tests. One checks the correct removal of an intent-to-add file. The other checks that we still disallow removal of empty files, but is marked as expect_failure to indicate this compromise. If the intent-to-add feature is ever extended to differentiate between normal empty files and intent-to-add files, then the safety valve can be re-tightened.
