From b500d5e11ea67d29dd7be622f65571d611d6e9a3 Mon Sep 17 00:00:00 2001 From: Nicolas Pitre Date: Wed, 17 Feb 2010 14:05:56 -0500 Subject: [PATCH] fast-import: use the diff_delta() max_delta_size argument This let diff_delta() abort early if it is going to bust the given size limit. Also, only objects larger than 20 bytes are considered as objects smaller than that are most certainly going to produce larger deltas than the original object due to the additional headers.
