From 00f059e930f12ca7c66cf2ffbc6c4ae789912af7 Mon Sep 17 00:00:00 2001 From: Keith Packard Date: Sun, 27 Aug 2006 21:53:48 -0700 Subject: Eliminate global cache. Eliminate multi-arch cache code. With the removal of the in-directory cache files, and the addition of per-user cache directories, there is no longer any reason to preserve the giant global cache file. Eliminating of this unifies the cache structure and simplifies the overall caching strategies greatly. --- fc-cache/fc-cache.c | 3 +- src/fccache.c | 1051 ++++++--------------------------------------------- src/fccfg.c | 23 +- src/fcdir.c | 164 ++++---- src/fcint.h | 70 +--- 5 files changed, 203 insertions(+), 1108 deletions(-) diff --git a/fc-cache/fc-cache.c b/fc-cache/fc-cache.c index 29974b2..281f835 100644 --- a/fc-cache/fc-cache.c +++ b/fc-cache/fc-cache.c @@ -227,8 +227,7 @@ scanDirs (FcStrList *list, FcConfig *config, char *program, FcBool force, FcBool ret++;
