From a6d79aecf9bb27c27e3f9fbef544e190592f24b7 Mon Sep 17 00:00:00 2001 From: "graham.gower" Date: Fri, 20 Nov 2009 01:20:24 +0000 Subject: [PATCH] Clean up pkg_remove_orphan_dependent() and remove_autoinstalled(). This is motivated by a desire to remove usage of depends_str, but fixes real problems with these functions as a side effect. pkg_remove_orphan_dependent() works as advertised now. git-svn-id: http://opkg.googlecode.com/svn/trunk@341 e8e0d7a0-c8d9-11dd-a880-a1081c7ac358 --- libopkg/opkg_install.c | 128 +++++++++++++++++++++++++---------------- libopkg/opkg_remove.c | 100 ++++++++++++++++---------------- 2 files changed, 128 insertions(+), 100 deletions(-) diff --git a/libopkg/opkg_install.c b/libopkg/opkg_install.c index 5e8596b..e28f6b4 100644 --- a/libopkg/opkg_install.c +++ b/libopkg/opkg_install.c @@ -573,56 +573,83 @@ static int unpack_pkg_control_files(opkg_conf_t *conf, pkg_t *pkg) return 0;
