From 4a5e74feb1a75a479acbc2f839e930966fdc2f2f Mon Sep 17 00:00:00 2001 From: Elijah Newren Date: Thu, 26 Aug 2010 00:21:48 -0600 Subject: [PATCH] tree_entry_interesting(): Make return value more specific tree_entry_interesting() can signal to its callers not only if the given entry matches one of the specified paths, but whether all remaining paths will (or will not) match. When no paths are specified, all paths are considered interesting, so intead of returning 1 (this path is interesting) return 2 (all paths are interesting). This will allow the caller to avoid calling tree_entry_interesting() again, which theoretically should speed up tree walking. I am not able to measure any actual gains in practice, but it certainly can not hurt and seems to make the code more readable to me.
