Revision 1684c1b219e02c91655ad929f752f4f864c72faf authored by brian m. carlson on 24 December 2014, 23:05:39 UTC, committed by Junio C Hamano on 29 December 2014, 17:57:55 UTC 
rev-list: add an option to mark fewer edges as uninteresting
 
In commit fbd4a70 (list-objects: mark more commits as edges in
mark_edges_uninteresting - 2013-08-16), we marked an increasing number
of edges uninteresting.  This change, and the subsequent change to make
this conditional on --objects-edge, are used by --thin to make much
smaller packs for shallow clones.

Unfortunately, they cause a significant performance regression when
pushing non-shallow clones with lots of refs (23.322 seconds vs.
4.785 seconds with 22400 refs).  Add an option to git rev-list,
--objects-edge-aggressive, that preserves this more aggressive behavior,
while leaving --objects-edge to provide more performant behavior.
Preserve the current behavior for the moment by using the aggressive
option.
