From 8375ad214a2a8d6e01430f432aa7957688d8ec52 Mon Sep 17 00:00:00 2001 From: Dan McGee Date: Mon, 19 Sep 2011 23:47:06 -0500 Subject: _alpm_sync_commit: extract two static methods This adds two new static methods, check_validity() and load_packages(), to sync.c which are simply code fragments pulled out of our do-everything sync commit code.
