From 74ebf82229829bbdbe74a4d9a7b6f29d2889dfc8 Mon Sep 17 00:00:00 2001 From: Mark Lodato Date: Sun, 31 Jan 2010 01:07:41 -0500 Subject: ui-plain: more efficient walk_tree() Git's read_tree_recursive() already filters out the objects by pathname, so we only have to compare baselen to the expected. That is, no string matching is required. Additionally, if the requested path is a directory, the old code would walk through all of its immediate children. This is not necessary, this so we no longer do that.
