It also said, that there is an sql injection problem (this came from our plugin to Phan). I double checked and the column as well as the argument are both properly escaped.

}

if ($builder->execute()) {
return (int)$this->connection->lastInsertId('*PREFIX*filecache');
}
} catch(UniqueConstraintViolationException $e) {
// entry exists already
}

// The file was created in the mean time
if (($id = $this->getId($file)) > -1) {
$this->update($id, $data);
return $id;
} else {
throw new \RuntimeException('File entry could not be inserted with insertIfNotExist() but could also not be selected with getId() in order to perform an update. Please try again.');
