[PATCH] Show more details of packfile with verify-pack -v.
This implements show_pack_info() function used in verify-pack command when -v flag is used to obtain something like unpack-objects used to give when it was first written. It shows the following for each non-deltified object found in the pack: SHA1 type size offset For deltified objects, it shows this instead: SHA1 type size offset depth base_sha1 In order to get the output in the order that appear in the pack file for debugging purposes, you can do this: $ git-verify-pack -v packfile | sort -n -k 4,4 Signed-off-by: Junio C Hamano <junkio@cox.net> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
