KohanaPHP » Kohana v3.x

There are quite a few framework settings which depend on environment, like the `Kohana::init()` parameters, Route / CFS caching, etc.
Frameworks' default is Kohana::DEVELOPMENT, ending up with most users not even using environment states.

1. default .htaccess should contain SetEnv KOHANA_ENV DEVELOPMENT
2. `Kohana::init()` call in bootstrap should contain some env-dependant definitions (maybe even all parameters in this array should be passed with default values instead of having the defaults defined inside of this method):

Kohana::init(array(
    'base_url'       => (Kohana::$environment == Kohana::PRODUCTION) ? '/' : '/kohana/',
    'index_file'    => (Kohana::$environment == Kohana::PRODUCTION) ? FALSE : 'index.php',
    'caching'    => Kohana::$environment  <  Kohana::DEVELOPMENT,
    'errors'    => Kohana::$environment  >  Kohana::PRODUCTION,
    'profile'    => Kohana::$environment  >  Kohana::PRODUCTION,
));

3. Most users don't even know that Routes can be cached, the default should be:

/**
 * Load routes if they're not cached yet
 */
if ( ! Route::cache())
{
    Route::set('default', '(<controller>(/<action>(/<id>)))(.<format>)', array('format' => 'html|json|xml'))
        ->defaults(array(
            'controller' => 'index',
            'action'     => 'index',
        ));

    // Cache all Routes if caching is enabled
    Route::cache(Kohana::$caching);
}

I'm quite sure there are many other things this methodology can be applied to, as long as they're not the things which can produce unexpected behaviour (default configs like in #4203).
