symfony/UPGRADE-2.1.md

UPGRADE FROM 2.0 to 2.1

• assets_base_urls and base_urls merging strategy has changed

  Unlike most configuration blocks, successive values for assets_base_urls will overwrite each other instead of being merged. This behavior was chosen because developers will typically define base URL's for each environment. Given that most projects tend to inherit configurations (e.g. config_test.yml imports config_dev.yml) and/or share a common base configuration (i.e. config.yml), merging could yield a set of base URL's for multiple environments.

• moved management of the locale from the Session class to the Request class

  Configuring the default locale:

  Before:

  framework:
    session:
        default_locale: fr
  

  After:

  framework:
    default_locale: fr
  

  Retrieving the locale from a Twig template:

  Before: {{ app.request.session.locale }} or {{ app.session.locale }} After: {{ app.request.locale }}

  Retrieving the locale from a PHP template:

  Before: $view['session']->getLocale() After: $view['request']->getLocale()

  Retrieving the locale from PHP code:

  Before: $session->getLocale() After: $request->getLocale()

• Method equals of Symfony\Component\Security\Core\User\UserInterface has moved to Symfony\Component\Security\Core\User\EquatableInterface.

  You have to change the name of the equals function in your implementation of the User class to isEqualTo and implement EquatableInterface. Apart from that, no other changes are required to make it behave as before. Alternatively, you can use the default implementation provided by AbstractToken:hasUserChanged if you do not need any custom comparison logic. In this case do not implement the interface and remove your comparison function.

  Before:

  class User implements UserInterface
  {
      // ...
      public function equals(UserInterface $user) { /* ... */ }
      // ...
  }
  

  After:

  class User implements UserInterface, EquatableInterface
  {
      // ...
      public function isEqualTo(UserInterface $user) { /* ... */ }
      // ...
  }
