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. Signed-off-by: brian m. carlson <sandals@crustytoothpaste.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
