UPGRADE FROM 4.1 to 4.2
|
|
=======================
|
|
|
|
Cache
|
|
-----
|
|
|
|
* Deprecated `CacheItem::getPreviousTags()`, use `CacheItem::getMetadata()` instead.
|
|
|
|
Config
|
|
------
|
|
|
|
* Deprecated constructing a `TreeBuilder` without passing root node information.
|
|
|
|
DoctrineBridge
|
|
--------------
|
|
|
|
* The `lazy` attribute on `doctrine.event_listener` tags was removed.
|
|
Listeners are now lazy by default. So any `lazy` attributes can safely be removed from those tags.
|
|
|
|
Form
|
|
----
|
|
|
|
* Deprecated calling `FormRenderer::searchAndRenderBlock` for fields which were already rendered.
|
|
Instead of expecting such calls to return empty strings, check if the field has already been rendered.
|
|
|
|
Before:
|
|
```twig
|
|
{% for field in fieldsWithPotentialDuplicates %}
|
|
{{ form_widget(field) }}
|
|
{% endfor %}
|
|
```
|
|
|
|
After:
|
|
```twig
|
|
{% for field in fieldsWithPotentialDuplicates if not field.rendered %}
|
|
{{ form_widget(field) }}
|
|
{% endfor %}
|
|
```
|
|
|
|
Security
|
|
--------
|
|
|
|
* Using the `has_role()` function in security expressions is deprecated, use the `is_granted()` function instead.
|
|
* Not returning an array of 3 elements from `FirewallMapInterface::getListeners()` is deprecated, the 3rd element
|
|
must be an instance of `LogoutListener` or `null`.
|
|
* Passing custom class names to the
|
|
`Symfony\Component\Security\Core\Authentication\AuthenticationTrustResolver` to define
|
|
custom anonymous and remember me token classes is deprecated. To
|
|
use custom tokens, extend the existing `Symfony\Component\Security\Core\Authentication\Token\AnonymousToken`
|
|
or `Symfony\Component\Security\Core\Authentication\Token\RememberMeToken`.
|
|
|
|
SecurityBundle
|
|
--------------
|
|
|
|
* Passing a `FirewallConfig` instance as 3rd argument to the `FirewallContext` constructor is deprecated,
|
|
pass a `LogoutListener` instance instead.
|
|
* Using the `security.authentication.trust_resolver.anonymous_class` and
|
|
`security.authentication.trust_resolver.rememberme_class` parameters to define
|
|
the token classes is deprecated. To use
|
|
custom tokens extend the existing AnonymousToken and RememberMeToken.
|
|
|
|
Serializer
|
|
----------
|
|
|
|
* Relying on the default value (false) of the "as_collection" option is deprecated since 4.2.
|
|
You should set it to false explicitly instead as true will be the default value in 5.0.
