repack: place temporary packs under .git/objects/pack/

trast · gitster · commit e32dfec79f99 · 2010-10-19T09:23:24.000-07:00
git-pack-objects is already careful to start out its temporary packs under .git/objects/pack/ (cf. 8b4eb6b, Do not perform cross-directory renames when creating packs, 2008-09-22), but git-repack did not respond in kind so the effort was lost when the filesystem boundary is exactly at that directory. Let git-repack pass a path under .git/objects/pack/ as the base for its temporary packs. This means we might need the $PACKDIR sooner (before the pack-objects invocation), so move the mkdir up just to be safe. Also note that the only use of *.pack is in the find invocation way before the pack-objects call, so the temporary packs will not suddenly show up in any wildcards because of the directory change.
