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
This allows for better conventions and better error messages if you
use the wrong configuration alias in a config file.
This is also the first step for a bigger refactoring of how the configuration
works (see next commits).
* Bundle::registerExtensions() method has been renamed to Bundle::build()
* The "main" DIC extension must be renamed to the new convention to be
automatically registered:
SensioBlogBundle -> DependencyInjection\SensioBlogExtension
* The main DIC extension alias must follow the convention:
sensio_blog for SensioBlogBundle
* If you have more than one extension for a bundle (which should really
never be the case), they must be registered manually by overriding the
build() method
* If you use YAML or PHP for your configuration, renamed the following
configuration entry points in your configs:
app -> framework
webprofiler -> web_profiler
doctrine_odm -> doctrine_mongo_db
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.
XML/YAML loaders assume imported resources are files before attempting to resolve their loader. This is problematic for loaders such as Assetic, which does not use a file as its resource. Furthermore, the previous consecutive calls to both locate() and getAbsolutePath() were redundant. File location can safely be delayed until FileLoader::import(), and we can let that throw an exception if the file is not found.

Rules are :
- If one of the ESI has validation cache strategy, the whole page will be
forced to validate.
- In none of the ESI has validation, the response will feature a Cache-Control
directive with s-maxage value equals to the smallest TTL of ESIs.
The merging is done in three steps:
1. Normalization:
=================
All passed config arrays will be transformed into the same structure
regardless of what format they come from.
2. Merging:
===========
This is the step when the actual merging is performed. Starting at the root
the configs will be passed along the tree until a node has no children, or
the merging of sub-paths of the current node has been specifically disabled.
Left-Side Right-Side Merge Result
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-nothing- array Right-Side will be taken.
scalar scalar Right-Side will be taken.
array false Right-Side will be taken if ->canBeUnset()
was called on the array node.
false array Right-Side will be taken.
array array Each value in the array will be passed to
the specific child node, or the prototype
node (whatever is present).
3. Finalization:
================
The normalized, and merged config will be passed through the config tree to
perform final validation on the submitted values, and set default values
where this has been requested.
You can influence this process in various ways, here is a list with some examples.
All of these methods must be called on the node on which they should be applied.
* isRequired(): Node must be present in at least one config file.
* requiresAtLeastOneElement(): PrototypeNode must have at least one element.
* treatNullLike($value): Replaces null with $value during normalization.
* treatTrueLike($value): Same as above just for true
* treatFalseLike($value): Same as above just for false
* defaultValue($value): Sets a default value for this node (only for scalars)
* addDefaultsIfNotSet(): Whether to add default values of an array which has not
been defined in any configuration file.
* disallowNewKeysInSubsequentConfigs(): All keys for this array must be defined
in one configuration file, subsequent
configurations may only overwrite these.
* fixXmlConfig($key, $plural = null): Transforms XML config into same structure
as YAML, and PHP configurations.
* useAttributeAsKey($name): Defines which XML attribute to use as array key.
* cannotBeOverwritten(): Declares a certain sub-path as non-overwritable. All
configuration for this path must be defined in the same
configuration file.
* cannotBeEmpty(): If value is set, it must be non-empty.
* canBeUnset(): If array values should be unset if false is specified.
Architecture:
=============
The configuration consists basically out of two different sets of classes.
1. Builder classes: These classes provide the fluent interface and
are used to construct the config tree.
2. Node classes: These classes contain the actual logic for normalization,
merging, and finalizing configurations.
After you have added all the metadata to your builders, the call to
->buildTree() will convert this metadata to actual node classes. Most of the
time, you will not have to interact with the config nodes directly, but will
delegate this to the Processor class which will call the respective methods
on the config node classes.
This commit removes CollectionToStringTransformer. Transformers should never change the state of the outside world, otherwise hard-to-track bugs might creap in.
This functionality needs to be implemented as a custom FieldType (see EntityChoiceField).
The implication is that set<Reference>() in the object of the parent form will not be called (and thus not has to be implemented/public).
If you want to suppress this behaviour, manually set "by_reference" to false.
Previously, the Definition class was used both for type inference and factory construction (if factoryService was absent). This is fine for cases where classes create instances of themselves (e.g. getInstance() or create()), but leads to ambiguity when we have a separate factory class.
Separated validation of data and form had serious drawbacks. When a form had nested form whose data was not connected to the data of the root form, this data would not be validated.
The new implementation validates the whole object graph at once. Class Form has a new method validateData(), that manually passes the data to the GraphWalker of the Validator and overrides the Default group with the groups set in the form.
This is mainly intended for complex configurations to ease the work you
have with normalizing different configuration formats (YAML, XML, and PHP).
First, you have to set-up a config tree:
$treeBuilder = new TreeBuilder();
$tree = $treeBuilder
->root('security_config', 'array')
->node('access_denied_url', 'scalar')->end()
->normalize('encoder')
->node('encoders', 'array')
->key('class')
->prototype('array')
->before()->ifString()->then(function($v) { return array('algorithm' => $v); })->end()
->node('algorithm', 'scalar')->end()
->node('encode_as_base64', 'scalar')->end()
->node('iterations', 'scalar')->end()
->end()
->end()
->end()
->buildTree()
;
This tree and the metadata attached to the different nodes is then used
to intelligently transform the passed config array:
$normalizedConfig = $tree->normalize($config);
