From 8e11e0c7198f7c7bdeb6ca76d647d4831593b965 Mon Sep 17 00:00:00 2001 From: Nagy Gabor <ngaba@bibl.u-szeged.hu> Date: Mon, 17 Nov 2008 17:02:43 +0100 Subject: [PATCH] Give an error message on alpm_db_register_sync() error
This patch slightly modifies pacman.c/_parseconfig():
See FS#12148. Now pacman prints the following error message in that case: "error: could not register 'unstable' database (could not open database)"
I also added an error message for alpm_db_setserver() error.
I changed the "return(1);" scheme to "ret = 1; goto clean_up;" to make sure that we free allocated memory and close open files.
