22115	Further Simplifying errors	msolution		"tracking errors while making API's and cron jobs, is a tad difficult.

from the latest wordpress pack, '''''/includes/wp-db.php'''''

{{{
function query( $query ) {
...
...
if ( defined( 'SAVEQUERIES' ) && SAVEQUERIES )
	$this->queries[] = array( $query, $this->timer_stop(), $this->get_caller() );

// If there is an error then take note of it..
if ( $this->last_error = mysql_error( $this->dbh ) ) {
	$this->print_error();
	return false;
}
...
...
}}}

if we change the above to simply

{{{
// If there is an error then take note of it..
$this->last_error = '';
if ( $this->last_error = mysql_error( $this->dbh ) )
	$this->print_error();

if ( defined( 'SAVEQUERIES' ) && SAVEQUERIES )
	$this->queries[] = array( $query, $this->timer_stop(), $this->get_caller(), $this->last_error );

// If there is an error then take note of it..
if ( ! empty( $this->last_error ) )
	return false;
}}}

then we have all required info in the array queries, for use later. may it be wp_footer, or for a plugin as debug info."	enhancement	new	normal	Future Release	Database	3.4.2	normal		2nd-opinion dev-feedback has-patch	msolution
