From 8da197755450d4f16018bd4b5486dc8ed88b0f2a Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Wed, 20 Sep 2006 22:02:01 -0700 Subject: Tell between packed, unpacked and symbolic refs. This adds a "int *flag" parameter to resolve_ref() and makes for_each_ref() family to call callback function with an extra "int flag" parameter. They are used to give two bits of information (REF_ISSYMREF and REF_ISPACKED) about the ref.
