The locale management does not require sessions anymore.
In the Symfony2 spirit, the locale should be part of your URLs. If this is the case
(via the special _locale request attribute), Symfony will store it in the request
(getLocale()).
This feature is now also configurable/replaceable at will as everything is now managed
by the new LocaleListener event listener.
How to upgrade:
The default locale configuration has been moved from session to the main configuration:
Before:
framework:
session:
default_locale: en
After:
framework:
default_locale: en
Whenever you want to get the current locale, call getLocale() on the request (was on the
session before).
Builds upon aead4a9836180cabae4d47fe27c634dcd79ac8f2, which prematurely removed request scoping from the assets templating helper in all cases. The helper need only be request-scoped if one or more request-scoped packages (e.g. PathPackages) are injected into it. This change makes it possible to utilize the assets helper outside of a request (e.g. during a console script).
To ensure that the assets helper is not assigned a request scope, all asset base URL's must be defined for all packages (default and any named) and both protocols: HTTP and SSL. The included test config fixtures concisely accomplish this by specifying a single HTTPS URL as the base URL for our default and named package, since FrameworkExtension's Configuration conveniently registers this URL for both protocols.

Router fix
Right now, the router is hard to overwrite (you need always a compiler pass). This commit fixes this.

Why do you need a complier pass to override the router?
---------------------------------------------------------------------------
by schmittjoh at 2011/07/18 01:47:47 -0700
How would you suggest to overwrite it?
Basically, I want to do something like this:
```yml
services:
router:
parent: router.default
class: MyClass
calls:
- [moreDeps, []]
```
---------------------------------------------------------------------------
by Seldaek at 2011/07/18 05:07:19 -0700
Then maybe we should somehow support redefining services with the same name while keeping the old one as parent, otherwise we need this foo.default for every service out there?
---------------------------------------------------------------------------
by fabpot at 2011/07/18 06:30:34 -0700
as @Seldeak said, why do that for the router and not all services?
---------------------------------------------------------------------------

I have designed the SecurityBundle this way where extension is encouraged.
---------------------------------------------------------------------------

I should add that this is mainly a problem for services where you still want to use the semantic configuration that is provided by the bundle. For services which are not configured by the extension, this is not so much of an issue.
Anyway, if you don't want to merge it, just close the PR. I have no problem with using a compiler pass.
---------------------------------------------------------------------------

We already have such a case with translator and translator.real. I will review the existing services to see where it makes sense to implement the same strategy.
---------------------------------------------------------------------------
by Seldaek at 2011/07/18 12:20:55 -0700
I guess you'd do it anyway, but we should pick a winner between .real and .default
---------------------------------------------------------------------------

I would prefer ".default" as ".real" always confused me.
Here are the new simplified rules:
* Required cache warmers are *always* executed when the Kernel boots for the first time;
* Optional cache warmers are *only* executed from the CLI via cache:warmup
These new rules means that all the configuration settings for the cache
warmers have been removed. So, if you want the best performance, remember to
warmup the cache when going to production.
This also fixed quite a few bugs.
* made the options array only for "global" options that are valid for all session storages
* changed the PDO session storage constructor signature to accept an array of options for DB configuration
* changed the storage_id to be the full service id, instead of just part of it
* removed the class parameter for session as it can be changed via the .class parameter (it was the only example in the framework)
* removed the configuration for the PDO session storage for now
The parameter has been removed and the service moved to the XML file (for consistency).
The behavior is still the same as before as any non-public service
which is not referenced anywhere will be automatically removed by a
compiler pass.
Controllers:
"BlogBundle:Post:show" is now "Blog:Post:show"
Templates:
"BlogBundle:Post:show.html.twig" is now "Blog:Post:show.html.twig"
Resources:
"@BlogBundle/Resources/config/blog.xml" is now "@Blog/Resources/config/blog.xml"
Doctrine:
"$em->find('BlogBundle:Post', $id)" is now "$em->find('Blog:Post', $id)"
How to upgrade?
For XML configuration files:
* All extensions should now use the config tag (this is just a convention as
the YAML configurations files do not use it anymore):
* The previous change means that the doctrine and security bundles now are
wrapped under a main "config" tag:
<doctrine:config>
<doctrine:orm />
<doctrine:dbal />
</doctrine:config>
<security:config>
<security:acl />
...
</security:config>
For YAML configuration files:
* The main keys have been renamed as follows:
* assetic:config -> assetic
* app:config -> framework
* webprofiler:config -> web_profiler
* doctrine_odm.mongodb -> doctrine_mongo_db
* doctrine:orm -> doctrine: { orm: ... }
* doctrine:dbal -> doctrine: { dbal: ... }
* security:config -> security
* security:acl -> security: { acl: ... }
* twig.config -> twig
* zend.config -> zend
* Remove redundant null/true equivalent array() values for array nodes
* Profiler matcher should not be deep merged; subsequent configs can simply overwrite its array
* Per lsmith's suggestion, change "isset(x) && x" to "!empty(x)"
* Templating engines node should be required, which is necessary to ensure requiresAtLeastOneElement() applies to its prototype children
In routing files, import statements allow an optional "type" option to hint the resources' type (e.g. for ambiguous file extensions). This adds the same type option to the FrameworkExtension config, which defines the main routing resource.
This reverts commit f53080860a.
Revert "[Router] config fixes"
This reverts commit 51beecc6f2.
Revert "moved duplicated files to a new Config component"
This reverts commit a8ec9b27f0.
This fixes some BC problems introduced in f9138d313b. Some top-level can now be simply enabled by providing true/null in PHP/YAML. Additionally, the Configuration\Builder allows options to be unset by providing "false" (helpful for overriding activation in a previous config file). All options supporting these behaviors can be found in the Configuration.php file (look for canBeUnset() and treatNull/TrueLike()).
Major changes:
* Removed "enabled" option for profiler config. Profiler is now enabled if its config is true, null or a map.
* Restore original config structure for validation namespaces. In PHP/YAML, namespaces are defined under annotations as an alternative to false (disabled) and true/null (enabled). For XML, annotation remains a boolean attribute for validation and a one or more optional namespace tags may appear within <app:validation />. During config normalization, namespace tags under validation will be moved to annotations to conform to the PHP/YAML structure (this occurs transparently to the user).
* Restore behavior for router/templating config sections being optional (as shown in changes to session/validation test fixtures). If either top-level section is unset in the configuration, neither feature will be enabled and the user will no longer receive exceptions due to missing a resource option (router) or engines (templating). Resource/engines will still be properly required if the respective feature is enabled.
* Remove unused router type option from XML config XSD. Type is only relevant for import statements, so this option is likely useless.
Additional small changes:
* Added isset()'s, since config options may be unset
* Wrap registerXxxConfiguration() calls in isset() checks
* Load translation.xml in configLoad(), since it's always required
* Default cache_warmer value (!kernel.debug) is determined via Configuration class
Things to be fixed:
* Configuration\Builder doesn't seem to respect isRequired() and requiresAtLeastOneElement() (or I haven't set it properly); this should replace the need for FrameworkExtension to throw exceptions for bad router/templating configs
* The config nodes for session options don't have the "pdo." prefix, as dots are not allowed in node names. To preserve BC for now, the "pdo." prefix is still allowed (and mandated by XSD) in configuration files. In the future, we may just want to do away with the "pdo." prefix.
* Translator has an "enabled" option. If there's no use case for setting "fallback" independently (when "enabled" is false), perhaps "enabled" should be removed entirely and translator should function like profiler currently does.
* Profiler matcher merging might need to be adjusted so multiple configs simply overwrite matcher instead of merging its array keys.
Restructured config format to make processing more straightforward. Important changes that might break existing configs:
* Added "enabled" option for translator (improves multi-format compat)
* Removed hash variation of validation annotations option (only boolean)
* Moved namespace option directly under validation (improves multi-format compat)
The new merge process depends on an internal array of all supported options and their default values, which is used for both validating the config schema and inferring how to merge options (as an added benefit, it helps make the extension self-documenting). Exceptions will now be thrown for merge errors resulting from unrecognized options or invalid types. Since incoming configurations are all merged atop the defaults, many isset() checks were removed. As a rule of thumb, we probably only want to ignore null values when an option would be used to set a parameter.
Also:
* Added missing attributes to symfony-1.0.xsd
* profiler: added only-exceptions attribute
* session: fix types and add pdo attributes
* Create FrameworkExtension tests with PHP/XML/YAML fixtures
* Use "%" syntax instead of calling getParameter() within FrameworkExtension
* Normalize config keys and arrays with helper methods for PHP/XML/YAML compatibility
Earlier changes:
* Remove nonexistent "DependencyInjection/Resources/" path from XmlFileLoaders
* Remove hasDefinition() checks, as register methods should only execute once
* Remove first-run logic from registerTranslatorConfiguration(), as it is only run once
* Removed apparently obsolete clearTags() calls on definitions for non-enabled features
You must now explicitly register the templating engine you want to use:
<app:templating>
<app:engine id="twig" />
</app:templating>
app.templating:
engines: ['twig']
Symfony2 comes with two such engines: 'twig', and 'php'.
This adds lazy loading for firewall configurations. This is useful when you have multiple firewalls, only the firewalls which are actually needed to process the Request are initialized. So, your event dispatcher is not as costly to initialize anymore.
It also implements re-using of RequestMatchers if all matching rules are the same, and exposes the remaining rules which are already implemented by the request matcher (host, ip, methods) in the access-control section
Before I explain the changes, let's talk about the current state.
Before this patch, the registerBundleDirs() method returned an ordered (for
resource overloading) list of namespace prefixes and the path to their
location. Here are some problems with this approach:
* The paths set by this method and the paths configured for the autoloader
can be disconnected (leading to unexpected behaviors);
* A bundle outside these paths worked, but unexpected behavior can occur;
* Choosing a bundle namespace was limited to the registered namespace
prefixes, and their number should stay low enough (for performance reasons)
-- moreover the current Bundle\ and Application\ top namespaces does not
respect the standard rules for namespaces (first segment should be the
vendor name);
* Developers must understand the concept of "namespace prefixes" to
understand the overloading mechanism, which is one more thing to learn,
which is Symfony specific;
* Each time you want to get a resource that can be overloaded (a template for
instance), Symfony would have tried all namespace prefixes one after the
other until if finds a matching file. But that can be computed in advance
to reduce the overhead.
Another topic which was not really well addressed is how you can reference a
file/resource from a bundle (and take into account the possibility of
overloading). For instance, in the routing, you can import a file from a
bundle like this:
<import resource="FrameworkBundle/Resources/config/internal.xml" />
Again, this works only because we have a limited number of possible namespace
prefixes.
This patch addresses these problems and some more.
First, the registerBundleDirs() method has been removed. It means that you are
now free to use any namespace for your bundles. No need to have specific
prefixes anymore. You are also free to store them anywhere, in as many
directories as you want. You just need to be sure that they are autoloaded
correctly.
The bundle "name" is now always the short name of the bundle class (like
FrameworkBundle or SensioCasBundle). As the best practice is to prefix the
bundle name with the vendor name, it's up to the vendor to ensure that each
bundle name is unique. I insist that a bundle name must be unique. This was
the opposite before as two bundles with the same name was how Symfony2 found
inheritance.
A new getParent() method has been added to BundleInterface. It returns the
bundle name that the bundle overrides (this is optional of course). That way,
there is no ordering problem anymore as the inheritance tree is explicitely
defined by the bundle themselves.
So, with this system, we can easily have an inheritance tree like the
following:
FooBundle < MyFooBundle < MyCustomFooBundle
MyCustomFooBundle returns MyFooBundle for the getParent() method, and
MyFooBundle returns FooBundle.
If two bundles override the same bundle, an exception is thrown.
Based on the bundle name, you can now reference any resource with this
notation:
@FooBundle/Resources/config/routing.xml
@FooBundle/Controller/FooController.php
This notation is the input of the Kernel::locateResource() method, which
returns the location of the file (and of course it takes into account
overloading).
So, in the routing, you can now use the following:
<import resource="@FrameworkBundle/Resources/config/internal.xml" />
The template loading mechanism also use this method under the hood.
As a bonus, all the code that converts from internal notations to file names
(controller names: ControllerNameParser, template names: TemplateNameParser,
resource paths, ...) is now contained in several well-defined classes. The
same goes for the code that look for templates (TemplateLocator), routing
files (FileLocator), ...
As a side note, it is really easy to also support multiple-inheritance for a
bundle (for instance if a bundle returns an array of bundle names it extends).
However, this is not implemented in this patch as I'm not sure we want to
support that.
How to upgrade:
* Each bundle must now implement two new mandatory methods: getPath() and
getNamespace(), and optionally the getParent() method if the bundle extends
another one. Here is a common implementation for these methods:
/**
* {@inheritdoc}
*/
public function getParent()
{
return 'MyFrameworkBundle';
}
/**
* {@inheritdoc}
*/
public function getNamespace()
{
return __NAMESPACE__;
}
/**
* {@inheritdoc}
*/
public function getPath()
{
return strtr(__DIR__, '\\', '/');
}
* The registerBundleDirs() can be removed from your Kernel class;
* If your code relies on getBundleDirs() or the kernel.bundle_dirs parameter,
it should be upgraded to use the new interface (see Doctrine commands for
many example of such a change);
* When referencing a bundle, you must now always use its name (no more \ or /
in bundle names) -- this transition was already done for most things
before, and now applies to the routing as well;
* Imports in routing files must be changed:
Before: <import resource="Sensio/CasBundle/Resources/config/internal.xml" />
After: <import resource="@SensioCasBundle/Resources/config/internal.xml" />
* 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
The SecurityFactories expect security services to have a consistent naming convention, which was not the case for providers defined as `{ id: another.service }`. These providers will now be aliased as "security.authentication.provider.[key]" and can be accessed in the same manner as other providers.
