# Breaking: #110028 - LoggerAwareInterface removed from FormEngine base classes

See [forge#110028](https://forge.typo3.org/issues/110028)

## Description

The FormEngine base classes
`\TYPO3\CMS\Backend\Form\AbstractNode` and
`\TYPO3\CMS\Backend\Form\FormDataProvider\AbstractDatabaseRecordProvider`
no longer implement `\Psr\Log\LoggerAwareInterface` and no longer use
`\Psr\Log\LoggerAwareTrait`.

Both base classes never read the injected logger themselves. The node hierarchy
built on `AbstractNode` does not use a logger at all. The two data provider
subclasses that did log, `\TYPO3\CMS\Backend\Form\FormDataProvider\TcaFiles`
and `\TYPO3\CMS\Backend\Form\FormDataProvider\TcaInline`, now receive a
`\Psr\Log\LoggerInterface` through their constructor instead.

## Impact

Subclasses of these base classes, for example custom FormEngine nodes or custom
database record providers shipped by extensions, are no longer recognized as
`\Psr\Log\LoggerAwareInterface` instances and no longer have a logger
injected automatically. The inherited `setLogger()` method is gone, and
reading the previously inherited `$logger` property raises an error.

## Affected installations

Instances with third-party extensions that subclass
`\TYPO3\CMS\Backend\Form\AbstractNode` or
`\TYPO3\CMS\Backend\Form\FormDataProvider\AbstractDatabaseRecordProvider`
and rely on the automatically injected logger.

## Migration

Request a `\Psr\Log\LoggerInterface` as a constructor argument in the
affected subclass. The subclass must be registered as a public service using the
`#[Autoconfigure(public: true)]` attribute, so that the FormEngine
`\TYPO3\CMS\Backend\Form\NodeFactory` obtains it through the dependency
injection container, which then resolves the constructor argument automatically.

```php
use Psr\Log\LoggerInterface;
use Symfony\Component\DependencyInjection\Attribute\Autoconfigure;
use TYPO3\CMS\Backend\Form\AbstractNode;

#[Autoconfigure(public: true)]
final class MyFormElement extends AbstractNode
{
    public function __construct(
        private readonly LoggerInterface $logger,
    ) {}

    public function render(): array
    {
        $this->logger->warning('Something the element wants to log');
        // ...
    }
}
```
