From 38a4556198de17156f27f0463161a4d1b5e11555 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Fri, 3 Jun 2011 15:32:15 -0700 Subject: [PATCH] index-pack: start learning to emulate "verify-pack -v" The "index-pack" machinery already has almost enough knowledge to produce the same output as "verify-pack -v". Fill small gaps in its bookkeeping, and teach it to show what it knows. Add a few more command line options that do not have to be advertised to the end users. They will be used internally when verify-pack calls this. The eventual goal is to remove verify-pack implementation and redo it as a thin wrapper around the index-pack, so that we can remove the rather expensive packed_object_info_detail() API. This still does not do the delta-chain-depth histogram yet but that part is easy.
