separating bundles for dev from the ones you need in production

Why is there no distinction of dev and prod in autoload.php as in AppKernel.php?

I could check the environment, of course, but I am wondering if there is a reason for that.

B/c many bundles are useful for development, for example the admin interface needs a lot of bundles (I guess...). But I don't want to load those during production!

autoload.php:

use Symfony\Component\ClassLoader\UniversalClassLoader;
use Doctrine\Common\Annotations\AnnotationRegistry;

$loader = new UniversalClassLoader();
$loader->registerNamespaces(array(
    'Symfony'          => array(__DIR__.'/../vendor/symfony/src', __DIR__.'/../vendor/bundles'),
    'Sensio'           => __DIR__.'/../vendor/bundles',
    'JMS'              => __DIR__.'/../vendor/bundles',
    'Doctrine\\Common' => __DIR__.'/../vendor/doctrine-common/lib',
    'Doctrine\\DBAL'   => __DIR__.'/../vendor/doctrine-dbal/lib',
    'Doctrine'         => __DIR__.'/../vendor/doctrine/lib',
    'Monolog'          => __DIR__.'/../vendor/monolog/src',
    'Assetic'          => __DIR__.'/../vendor/assetic/src',
    'Metadata'         => __DIR__.'/../vendor/metadata/src',
));
$loader->registerPrefixes(array(
    'Twig_Extensions_' => __DIR__.'/../vendor/twig-extensions/lib',
    'Twig_'            => __DIR__.'/../vendor/twig/lib',
));

AppKernel.php:

public function registerBundles()
    {
        $bundles = array(
            new Symfony\Bundle\FrameworkBundle\FrameworkBundle(),
            new Symfony\Bundle\SecurityBundle\SecurityBundle(),
            new Symfony\Bundle\TwigBundle\TwigBundle(),
            new Symfony\Bundle\MonologBundle\MonologBundle(),
            new Symfony\Bundle\SwiftmailerBundle\SwiftmailerBundle(),
            new Symfony\Bundle\DoctrineBundle\DoctrineBundle(),
            new Symfony\Bundle\AsseticBundle\AsseticBundle(),
            new Sensio\Bundle\FrameworkExtraBundle\SensioFrameworkExtraBundle(),
            new JMS\SecurityExtraBundle\JMSSecurityExtraBundle(),
        );

        if (in_array($this->getEnvironment(), array('dev', 'test'))) {
            $bundles[] = new Acme\DemoBundle\AcmeDemoBundle();
            $bundles[] = new Symfony\Bundle\WebProfilerBundle\WebProfilerBundle();
            $bundles[] = new Sensio\Bundle\DistributionBundle\SensioDistributionBundle();
            $bundles[] = new Sensio\Bundle\GeneratorBundle\SensioGeneratorBundle();
        }

        return $bundles开发者_如何转开发;
    }


First, the autoloader is a standalone library. You could use it in a totally different project not related to Symfony2 as it is totally not coupled. As it is not coupled, it has to be env agnostic.

Second, the autoloader does not have the same algorithm as symfony1 and does not cache where the file are located. It's made on the fly, and you'll got tons of other performances issues before this one ;)
