TYPO3 Core

Following TCA configuration for non pages records results in a Segmentation Fault because Slughelper::generate() is called infinitively.
This behavior was introduced with https://review.typo3.org/c/Packages/TYPO3.CMS/+/71059

'slug' => [
    'config' => [
        'type' => 'slug',
        'generatorOptions' => [
            'prefixParentPageSlug' => true,
        ],
    ],
]

The problem is, that for non pages records the $this->tableName is set to something else than pages. As a result the if-clause at the beginning of generate will not become true.

It do not know what the best solution might be. Maybe set $this->tableName = 'pages' after calling $this->resolveParentPageRecord()? But I am not sure whether this would always be true? Please let me know I would like to fix it!

I have created a test to reproduce the problem:

...
namespace TYPO3\CMS\Core\Tests\Unit\DataHandling

...

class SlugHelperTest extends UnitTestCase
{
    /**
     * @return array
     */
    public function generatePrependsSlugsForNonPagesDataProvider(): array
    {
        return [
            'simple title' => [
                'Product Name',
                '/parent-page/product-name',
                [
                    'generatorOptions' => [
                        'fields' => ['title'],
                        'prefixParentPageSlug' => true,
                    ],
                ],
            ],
        ];
    }

    /**
     * @dataProvider generatePrependsSlugsForNonPagesDataProvider
     * @param string $input
     * @param string $expected
     * @test
     */
    public function generatePrependsSlugsForNonPages(string $input, string $expected, array $options): void
    {
        $GLOBALS['dummyTable']['ctrl'] = [];
        $parentPage = [
            'uid' => '0',
            'pid' => null,
        ];
        $subject = $this->getAccessibleMock(
            SlugHelper::class,
            ['resolveParentPageRecord'],
            [
                'another_table',
                'slug',
                $options,
            ]
        );
        $subject->expects(self::any())
            ->method('resolveParentPageRecord')
            ->withAnyParameters()
            ->willReturn($parentPage);
        self::assertEquals(
            $expected,
            $subject->generate(['title' => $input, 'uid' => 13], 13)
        );
    }
}
