Unable to connect to the DB - CI 2

[eluser]DominixZ[/eluser]
I have unable to connect to the DB too in CodeIgniter 2 [Download from Repo at Nov 24]
but I cannot connect to the DB only from commandline


In commandline use like this

Code:

php cli.php "welcome/index"

and it happen like this

Code:

<div id="content">
        <h1>A Database Error Occurred</h1>
        <p>Unable to connect to your database server using the provided settings.</p><p>Filename: /Users/dominixz/Sites/onebitframework/controllers/welcome.php</p><p>Line Number: 19</p>    </div>

but If I open with browser no error.

cli.php I use from NetTuts this is code

Code:

#!/usr/bin/php
<?php
if (isset($_SERVER['REMOTE_ADDR'])) {
    die('Command Line Only!');
}

set_time_limit(0);

$_SERVER['PATH_INFO'] = $_SERVER['REQUEST_URI'] = $argv[1];

require dirname(__FILE__) . '/index.php';

This is work fine in CI 1.7.2

and I have another question CI 2.0 autoload "database" doesn't show error like CI1.7.2 isn't it ? because in CI 1.7.2 if i enter wrong username or password or database and i'm autoload it it will unable to connect instantly but in CI2.0 doesn't i must use some $this->db->get() and then it will be show error.

My Question is "Is it change behavior of this ? or it only me that have something like this ?"

Thank in advance
