Deprecation: #103965 - Deprecate namespaced shorthand validator usage in extbase

See 103965

Description

It is possible to use the undocumented namespaced shorthand notation in
extbase to add validators for properties or arguments. As an example,
TYPO3.CMS.Extbase:NotEmpty will be resolved as
TYPO3\CMS\Extbase\Validation\Validator\NotEmptyValidator or
Vendor.Extension:Custom will be resolved as
\Vendor\MyExtension\Validation\Validator\CustomValidator.

The namespaced shorthand notation for extbase validators has been marked
as deprecated and will be removed in TYPO3 v14.

Impact

Using namespaced shorthand notation in extbase will trigger a PHP
deprecation warning.

Affected installations

All installations using namespaced shorthand notation in extbase are
affected.

Migration

Extensions using the namespaced shorthand notation must use the FQCN of
the validator instead. In case of extbase core validators, the well
known shorthand validator name can be used.

Before

/**
 * @Extbase\Validate("TYPO3.CMS.Extbase:NotEmpty")
 */
protected $myProperty1;

/**
 * @Extbase\Validate("Vendor.Extension:Custom")
 */
protected $myProperty2;

After

/**
 * @Extbase\Validate("NotEmpty")
 */
protected $myProperty1;

/**
 * @Extbase\Validate("Vendor\Extension\Validation\Validator\CustomValidator")
 */
protected $myProperty2;

or

#[Extbase\Validate(['validator' => \TYPO3\CMS\Extbase\Validation\Validator\NotEmptyValidator::class])]
protected $myProperty1;

#[Extbase\Validate(['validator' => \Vendor\Extension\Validation\Validator\CustomValidator::class])]
protected $myProperty2;
