From 34110cd4e394e3f92c01a4709689b384c34645d8 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Thu, 6 Mar 2008 18:12:28 -0800 Subject: Make 'unpack_trees()' have a separate source and destination index We will always unpack into our own internal index, but we will take the source from wherever specified, and we will optionally write the result to a specified index (optionally, because not everybody even _wants_ any result: the index diffing really wants to just walk the tree and index in parallel). This ends up removing a fair number more lines than it adds, for the simple reason that we can now skip all the crud that tried to be oh-so-careful about maintaining our position in the index as we were traversing and modifying it. Since we don't actually modify the source index any more, we can just update the 'o->pos' pointer without worrying about whether an index entry got removed or replaced or added to.
