From 7dc37109b096b484fc569060cc896b5127419775 Mon Sep 17 00:00:00 2001 From: Nagy Gabor Date: Mon, 28 Jan 2008 01:44:23 +0100 Subject: alpm_sync_sysupgrade split This patch indroduces a new public alpm_sync_newversion, which scans for new version of a package in sync repos. Hopefully this will reduce code duplication in the future: * check-for-pacman-new-version from front-end can be easier * -Qu refactoring Signed-off-by: Nagy Gabor Signed-off-by: Chantry Xavier --- lib/libalpm/alpm.h | 1 + lib/libalpm/sync.c | 109 ++++++++++++++++++++++++++++++++--------------------- 2 files changed, 66 insertions(+), 44 deletions(-) (limited to 'lib') diff --git a/lib/libalpm/alpm.h b/lib/libalpm/alpm.h index bcc344d8..1177c251 100644 --- a/lib/libalpm/alpm.h +++ b/lib/libalpm/alpm.h @@ -249,6 +249,7 @@ const alpm_list_t *alpm_grp_get_pkgs(const pmgrp_t *grp);
