Let's take some examples to explain the change.
First, if you don't use any vendored bundles, this commit does not change anything.
So, let's say you use a FooBundle from Sensio. The files are stored under Bundle\Sensio\FooBundle.
And the Bundle class is Bundle\Sensio\FooBundle\SensioFooBundle.php.
Before the change, the bundle name ($bundle->getName()) would have returned 'FooBundle'.
Now it returns 'SensioFooBundle'.
Why does it matter? Well, it makes template names and controller names easier to read:
Before:
Template: Sensio\FooBundle:Bar:index.twig.html
Controller: Sensio\FooBundle:Bar:indexAction
After
Template: SensioFooBundle:Bar:index.twig.html
Controller: SensioFooBundle:Bar:indexAction
NB: Even if the change seems simple enough, the implementation is not. As finding
the namespace from the bundle class name is not trivial
NB2: If you don't follow the bundle name best practices, this will probably
leads to unexpected behaviors.
Before
bundle:section:template.format.renderer
After
bundle:section:template.renderer.format
Notice that both the renderer and the format are mandatory.
* better separation of concerns
* made TwigBundle independant of the PHP Engine from FrameworkBundle (WIP)
* removed one layer of abstraction in the Templating component (renderers)
* made it easier to create a new Engine for any templating library
* made engines lazy-loaded (PHP engine for instance is not started if you only use Twig)
* reduces memory footprint (if you only use one engine)
* reduces size of compiled classes.php cache file
These helpers have been removed as they do not work as expected.
Among other things, the order is not the right one when using PHP
templates, and adding assets from an included template is not
possible when using Twig templates.
This should be replaced by integrating a third-party library that
manages assets: minification, compilation, packaging, ...
Currently, ambiguities only arise for PHP files, as PhpFileLoader and AnnotationFileLoader would both claim support. Future conflicts may occur if the XML, YAML, or PHP loaders were to receive Directory and Glob loaders (as annotations have).
Since the "type" parameter is optional, loader resolution will default to awarding resolution to the first loader to claim support. A previous hack in PhpFileLoader to avoid an AnnotationFileLoader conflict was removed, so that should be the only lost backwards compatibility with this patch. Unit tests were also created for the various loader classes, although only the supports() method is being tested.
This implementation was proposed on the symfony-dev mailing list in response to Fabien's RFC for custom loader notation: http://groups.google.com/group/symfony-devs/browse_thread/thread/3104c1a9e45799d2/20fbe393c1afe088
Previously, HttpKernel performed request-stashing. By moving this to the Kernel class, the request is now available immediately after the kernel becomes aware of it. If the kernel is allowed to boot lazily (during the first call to handle()), this also allows an actual master Request to be available during booting.
The old "request" service definition (with a bogus class name) can be replaced with a factory-aware definition that retrieves the request directly from the kernel.
Support for theming in PHP templates has been dropped.
True theming should support theme inheritance, e.g. mytheme <- table <- default.
Currently, the Templating component does not support such inheritance. As the
only purpose of the themes so far was to style field groups with tables or
divs, and because automatic rendering of field groups/forms through the render()
method is discouraged and only recommended for rapid prototyping, themes are
dropped for now.
Modified the framework bundle to use validation => Symfony\Component\Validator\Validator defaults.
Enhanced Framework Extension validator configuration to allow to extend this configuration with
user-specified annotations, for example:
validation:
enabled: true
annotations:
namespaces:
myprojectvalidator: MyProject\Validator\
to register @myprojectvalidator:Validator(...)
Some explanations on how it works now:
* The Session is an optional dependency of the Request. If you create the
Request yourself (which is mandatory now in the front controller) and if
you don't inject a Session yourself (which is recommended if you want the
session to be configured via dependency injection), the Symfony2 Kernel
will associate the Session configured in the Container with the Request
automatically.
* When duplicating a request, the session is shared between the parent and
the child (that's because duplicated requests are sub-requests of the main
one most of the time.) Notice that when you use ::create(), the behavior is
the same as for the constructor; no session is attached to the Request.
* Symfony2 tries hard to not create a session cookie when it is not needed
but a Session object is always available (the cookie is only created when
"something" is stored in the session.)
* Symfony2 only starts a session when:
* A session already exists in the request ($_COOKIE[session_name()] is
defined -- this is done by RequestListener);
* There is something written in the session object (the cookie will be sent
to the Client).
* Notice that reading from the session does not start the session anymore (as
we don't need to start a new session to get the default values, and because
if a session exists, it has already been started by RequestListener.)
* removed the Kernel::registerRoutes() method
* added a router entry in <web:config> (replaces the registerRoutes() method)
<web:config>
<web:router resource="%kernel.root_dir%/config/routing.xml" />
</web:config>
* refactored routing configuration in its own routing.xml file (leverages the new routing component API),
which is loaded only if <web:router> is defined in the configuration
