pack-bitmap.c: support 'tree:0' filtering
In the previous patch, we made it easy to define other filters that exclude all objects of a certain type. Use that in order to implement bitmap-level filtering for the '--filter=tree:<n>' filter when 'n' is equal to 0. The general case is not helped by bitmaps, since for values of 'n > 0', the object filtering machinery requires a full-blown tree traversal in order to determine the depth of a given tree. Caching this is non-obvious, too, since the same tree object can have a different depth depending on the context (e.g., a tree was moved up in the directory hierarchy between two commits). But, the 'n = 0' case can be helped, and this patch does so. Running p5310.11 in this tree and on master with the kernel, we can see that this case is helped substantially: Test master this tree -------------------------------------------------------------------------------- 5310.11: rev-list count with tree:0 10.68(10.39+0.27) 0.06(0.04+0.01) -99.4% Signed-off-by: Taylor Blau <me@ttaylorr.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
