Methods within FormExtension later type-hint this parameter as an array, but it's convenient to allow a single string to be passed from Twig if we ensure it's wrapped in an array.
Updated load data fixtures command in DoctrineMongoDBBundle to be identical to the one in DoctrineBundle
Created custom loader, that passes $container to all ContainerAware DataFixtures
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.
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.
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).
