253Symfony Standard Edition Upgrade
================================
From Symfony 2.0 to Symfony 2.1
-------------------------------
### Project Dependencies
As of Symfony 2.1, project dependencies are managed by
[Composer](http://getcomposer.org/):
* The `bin/vendors` script can be removed as `composer.phar` does all the work
now (it is recommended to install it globally on your machine).
* The `deps` file need to be replaced with the `composer.json` one.
* The `composer.lock` is the equivalent of the generated `deps.lock` file and
it is automatically generated by Composer.
Download the default
[`composer.json`](https://raw.github.com/symfony/symfony-standard/master/composer.json)
and
[`composer.lock`](https://raw.github.com/symfony/symfony-standard/master/composer.lock)
files for Symfony 2.1 and put them into the main directory of your project. If
you have customized your `deps` file, move the added dependencies to the
`composer.json` file (many bundles and PHP libraries are already available as
Composer packages -- search for them on [Packagist](http://packagist.org/)).
Remove your current `vendor` directory.
Finally, run Composer:
$ composer.phar install
### `app/autoload.php`
The default `autoload.php` reads as follows (it has been simplified a lot as
autoloading for libraries and bundles declared in your `composer.json` file is
automatically managed by the Composer autoloader):
<?php
use Doctrine\Common\Annotations\AnnotationRegistry;
$loader = include __DIR__.'/../vendor/autoload.php';
// intl
if (!function_exists('intl_get_error_code')) {
require_once __DIR__.'/../vendor/symfony/symfony/src/Symfony/Component/Locale/Resources/stubs/functions.php';
$loader->add('', __DIR__.'/../vendor/symfony/symfony/src/Symfony/Component/Locale/Resources/stubs');
}
AnnotationRegistry::registerLoader(array($loader, 'loadClass'));
return $loader;
### `app/config/config.yml`
The `framework.charset` setting must be removed. If you are not using `UTF-8`
for your application, override the `getCharset()` method in your `AppKernel`
class instead:
class AppKernel extends Kernel
{
public function getCharset()
{
return 'ISO-8859-1';
}
// ...
}
You might want to add the new `strict_requirements` parameter to
`framework.router` (it avoids fatal errors in the production environment when
a link cannot be generated):
framework:
router:
strict_requirements: "%kernel.debug%"
The `default_locale` parameter is now a setting of the main `framework`
configuration (it was under the `framework.session` in 2.0):
framework:
default_locale: "%locale%"
The `auto_start` setting under `framework.session` must be removed as it is
not used anymore (the session is now always started on-demand). If
`auto_start` was the only setting under the `framework.session` entry, don't
remove it entirely, but set its value to `~` (`~` means `null` in YAML)
instead:
framework:
session: ~
The `trust_proxy_headers` setting was added in the default configuration file
(as it should be set to `true` when you install your application behind a
reverse proxy):
framework:
trust_proxy_headers: false
An empty `bundles` entry was added to the `assetic` configuration:
assetic:
bundles: []
The default `swiftmailer` configuration now has the `spool` setting configured
to the `memory` type to defer email sending after the response is sent to the
user (recommended for better end-user performance):
swiftmailer:
spool: { type: memory }
The `jms_security_extra` configuration was moved to the `security.yml`
configuration file.
### `app/config/config_dev.yml`
An example of how to send all emails to a unique address was added:
#swiftmailer:
# delivery_address: me@example.com
### `app/config/config_test.yml`
The `storage_id` setting must be changed to `session.storage.mock_file`:
framework:
session:
storage_id: session.storage.mock_file
### `app/config/parameters.ini`
The file has been converted to a YAML file which reads as follows:
parameters:
database_driver: pdo_mysql
database_host: localhost
database_port: ~
database_name: symfony
database_user: root
database_password: ~
mailer_transport: smtp
mailer_host: localhost
mailer_user: ~
mailer_password: ~
locale: en
secret: ThisTokenIsNotSoSecretChangeIt
Note that if you convert your parameters file to YAML, you must also change
its reference in `app/config/config.yml`.
### `app/config/routing_dev.yml`
The `_assetic` entry was removed:
#_assetic:
# resource: .
# type: assetic
### `app/config/security.yml`
Under `security.access_control`, the default rule for internal routes was changed:
security:
access_control:
#- { path: ^/_internal/secure, roles: IS_AUTHENTICATED_ANONYMOUSLY, ip: 127.0.0.1 }
Under `security.providers`, the `in_memory` example was updated to the following:
security:
providers:
in_memory:
memory:
users:
user: { password: userpass, roles: [ 'ROLE_USER' ] }
admin: { password: adminpass, roles: [ 'ROLE_ADMIN' ] }
### `app/AppKernel.php`
The following bundles have been added to the list of default registered bundles:
new JMS\AopBundle\JMSAopBundle(),
new JMS\DiExtraBundle\JMSDiExtraBundle($this),
### `web/app.php`
The default `web/app.php` file now reads as follows:
<?php
use Symfony\Component\ClassLoader\ApcClassLoader;
use Symfony\Component\HttpFoundation\Request;
$loader = require_once __DIR__.'/../app/bootstrap.php.cache';
// Use APC for autoloading to improve performance
// Change 'sf2' by the prefix you want in order to prevent key conflict with another application
/*
$loader = new ApcClassLoader('sf2', $loader);
$loader->register(true);
*/
require_once __DIR__.'/../app/AppKernel.php';
//require_once __DIR__.'/../app/AppCache.php';
$kernel = new AppKernel('prod', false);
$kernel->loadClassCache();
//$kernel = new AppCache($kernel);
$request = Request::createFromGlobals();
$response = $kernel->handle($request);
$response->send();
$kernel->terminate($request, $response);
### `web/app_dev.php`
The default `web/app_dev.php` file now reads as follows:
<?php
use Symfony\Component\HttpFoundation\Request;
// If you don't want to setup permissions the proper way, just uncomment the following PHP line
// read http://symfony.com/doc/current/book/installation.html#configuration-and-setup for more information
//umask(0000);
// This check prevents access to debug front controllers that are deployed by accident to production servers.
// Feel free to remove this, extend it, or make something more sophisticated.
if (isset($_SERVER['HTTP_CLIENT_IP'])
|| isset($_SERVER['HTTP_X_FORWARDED_FOR'])
|| !in_array(@$_SERVER['REMOTE_ADDR'], array(
'127.0.0.1',
'::1',
))
) {
header('HTTP/1.0 403 Forbidden');
exit('You are not allowed to access this file. Check '.basename(__FILE__).' for more information.');
}
$loader = require_once __DIR__.'/../app/bootstrap.php.cache';
require_once __DIR__.'/../app/AppKernel.php';
$kernel = new AppKernel('dev', true);
$kernel->loadClassCache();
$request = Request::createFromGlobals();
$response = $kernel->handle($request);
$response->send();
$kernel->terminate($request, $response);
