Just as rev-list recently learned to combine filters and bitmaps, let's do the same for pack-objects. The infrastructure is all there; we just need to pass along our filter options, and the pack-bitmap code will decide to use bitmaps or not. This unsurprisingly makes things faster for partial clones of large repositories (here we're cloning linux.git): Test HEAD^ HEAD ------------------------------------------------------------------------------ 5310.9: simulated partial clone 38.94(37.28+5.87) 11.06(11.27+4.07) -71.6% Signed-off-by: Jeff King <peff@peff.net> --- builtin/pack-objects.c | 3 +-- t/perf/p5310-pack-bitmaps.sh | 4 ++++ t/t5310-pack-bitmaps.sh | 14 ++++++++++++++ 3 files changed, 19 insertions(+), 2 deletions(-)
