prepare_packed_git_one() is modified to allow count-objects to hook a report function to so we don't need to duplicate the pack searching logic in count-objects.c. When report_pack_garbage is NULL, the overhead is insignificant. The garbage is reported with warning() instead of error() in packed garbage case because it's not an error to have garbage. Loose garbage is still reported as errors and will be converted to warnings later. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
