From ac5409e420e5fdd7c4a381f873ffcedfb83d7117 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Wed, 27 Sep 2006 01:58:57 -0700 Subject: update-ref: -d flag and ref creation safety. This adds -d flag to update-ref to allow safe deletion of ref. Before deleting it, the command checks if the given still matches the value the caller thought the ref contained. Similarly, it also accepts 0{40} or an empty string as to allow safe creation of a new ref.
