From 8e72a3c321eb70caad036e45664de9ea10839b93 Mon Sep 17 00:00:00 2001 From: Derrick Stolee Date: Thu, 13 Sep 2018 11:02:18 -0700 Subject: [PATCH] multi-pack-index: verify packname order The final check we make while loading a multi-pack-index is that the packfile names are in lexicographical order. Make this error be a die() instead. In order to test this condition, we need multiple packfiles. Earlier in t5319-multi-pack-index.sh, we tested the interaction with 'git repack' but this limits us to one packfile in our object dir. Move these repack tests until after the 'verify' tests.
