commit 1bd168f60e4d9a6dfc90bfb3b0dd18cf68d0f556
Author: Carlos Garnacho <carlosg gnome org>
Date: Wed May 19 11:46:26 2010 +0200
libtracker-[db|data]: Improve error checking on SQL calls.
A new GError parameter was added to tracker_db_interface_create_statement(), all
callers have been updated to handle errors where it made most sense. Also,
a bunch of calls to execute_query(), execute(), start_cursor() and iter_next()
have been changed to also check for errors.
