From 4aab5b46f44a7ba860e07a52be506b7b57b2bd5f Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Sun, 1 Apr 2007 23:26:07 -0700 Subject: Make read-cache.c "the_index" free. This makes all low-level functions defined in read-cache.c to take an explicit index_state structure as their first parameter, to specify which index to work on. These functions traditionally operated on "the_index" and were named foo_cache(); the counterparts this patch introduces are called foo_index(). The traditional foo_cache() functions are made into macros that give "the_index" to their corresponding foo_index() functions.
