Breaking: #96044 - Harden method signature of logicalAnd() and logicalOr()¶

Description¶

The method signature of \TYPO3\CMS\Extbase\Persistence\QueryInterface::logicalAnd() and \TYPO3\CMS\Extbase\Persistence\QueryInterface::logicalOr() changed. As a consequence the method signature of \TYPO3\CMS\Extbase\Persistence\Generic\Query::logicalAnd() and \TYPO3\CMS\Extbase\Persistence\Generic\Query::logicalOr() changed as well.

Both methods do no longer accept an array as first parameter. Furthermore both methods have two mandatory \TYPO3\CMS\Extbase\Persistence\Generic\Qom\ConstraintInterface parameters to form a logical conjunction on.

Both methods do indeed accept an infinite number of further constraints.

The logicalAnd() method does now reliably return an instance of \TYPO3\CMS\Extbase\Persistence\Generic\Qom\AndInterface instance while the logicalOr() method returns a \TYPO3\CMS\Extbase\Persistence\Generic\Qom\OrInterface instance.

Impact¶

This change impacts all usages of said methods with

either just one array parameter containing all constraints
or passing just a single constraint

An array is no longer accepted as first parameter because it does not guarantee the minimum number (2) of constraints is given.

Just one constraint is no longer accepted because in that case, the incoming constraint would have simply been returned which is not compatible with returning either a AndInterface or a OrInterface but just a ConstraintInterface.

Affected Installations¶

All installations that passed all constraints as array or that passed just one constraint.

Migration¶

The migration is the same for logicalAnd() and logicalOr() since their param signature is the same. The upcoming example will show a migration for a logicalAnd() call.

Example:

$query = $this->createQuery();
$query->matching($query->logicalAnd([
    $query->equals('propertyName1', 'value1'),
    $query->equals('propertyName2', 'value2'),
    $query->equals('propertyName3', 'value3'),
]));

In this case an array is used as one and only method argument. The migration is easy and quickly done. Simply don't use an array:

$query = $this->createQuery();
$query->matching($query->logicalAnd(
    $query->equals('propertyName1', 'value1'),
    $query->equals('propertyName2', 'value2'),
    $query->equals('propertyName3', 'value3'),
));

Things become a little more tricky as soon as the number of constraints is below 2 or unknown before runtime.

Example:

$constraints = [];

if (...) {
   $constraints[] = $query->equals('propertyName1', 'value1');
}

if (...) {
   $constraints[] = $query->equals('propertyName2', 'value2');
}

$query = $this->createQuery();
$query->matching($query->logicalAnd($constraints));

In this case there needs to be a distinction of number of constraints in the code base:

$constraints = [];

if (...) {
   $constraints[] = $query->equals('propertyName1', 'value1');
}

if (...) {
   $constraints[] = $query->equals('propertyName2', 'value2');
}

$query = $this->createQuery();

$numberOfConstraints = count($constraints);
if ($numberOfConstraints === 1) {
    $query->matching(reset($constraints));
} elseif ($numberOfConstraints >= 2) {
    $query->matching($query->logicalAnd(...$constraints));
}
