Environment

• Rector 0.17.7 (installed as composer dependency)
• Composer version 2.2.21 2023-02-15 13:07:40
• PHP 8.1.17 (cli) (built: Mar 16 2023 14:37:57) (NTS)

What should happen?
Rector processes the files in the given path and produces a diff output of the changes it has made. The command is:

$ rector process --autoload-file /var/www/html/wearemagneto/projects/hstv/html/vendor/autoload.php --config /var/www/html/wearemagneto/projects/hstv/html/rector.php /var/www/html/wearemagneto/projects/hstv/html/app/code/HSTV/Criteo/

The rector.php config file is:

<?php

declare(strict_types=1);

use Magento2\Rector\Src\ReplaceMbStrposNullLimit;
use Magento2\Rector\Src\ReplaceNewDateTimeNull;
use Rector\Config\RectorConfig;
use Rector\Core\ValueObject\PhpVersion;
use Rector\Php80\Rector\Class_\StringableForToStringRector;
use Rector\Php80\Rector\ClassMethod\FinalPrivateToPrivateVisibilityRector;
use Rector\CodeQuality\Rector\ClassMethod\OptionalParametersAfterRequiredRector;
use Rector\Php80\Rector\ClassMethod\SetStateToStaticRector;
use Rector\Php81\Rector\FuncCall\Php81ResourceReturnToObjectRector;
use Magento2\Rector\Src\ReplacePregSplitNullLimit;
use Rector\Set\ValueObject\LevelSetList;

return static function (RectorConfig $rectorConfig): void {
    $rectorConfig->phpVersion(PhpVersion::PHP_81);
[rector-bug-report.txt](https://github.com/rectorphp/rector/files/12228693/rector-bug-report.txt)

    $rectorConfig->sets([LevelSetList::UP_TO_PHP_81]);

    // get services (needed for register a single rule)
    $services = $rectorConfig->services();

    // register a single rule
    $services->set(FinalPrivateToPrivateVisibilityRector::class);
    $services->set(OptionalParametersAfterRequiredRector::class);
    $services->set(SetStateToStaticRector::class);
    $services->set(StringableForToStringRector::class);
    $services->set(Php81ResourceReturnToObjectRector::class);
    $services->set(ReplacePregSplitNullLimit::class);
    $services->set(ReplaceMbStrposNullLimit::class);
    $services->set(ReplaceNewDateTimeNull::class);
};

What actually happens?
Some file are processed successfully, but others fail with a fatal error: 'System error: "Failed to create directory "/tmp/cache/PHPStan" (Constant FILE_BINARY is deprecated)':

Running rector with debug flag produces this output:

Thanks for reporting. This seems like a file access issue due to your filesystem rights.

Instead of running Rector from outside project, install it at project itself:

cd /var/www/html/wearemagneto/projects/hstv/html
composer require rector/rector --dev

vendor/bin/rector

That way you avoid misslocations and long includes and autoloads :).

Also make sure the PHPStan and Rector can create files in your temp directory 👏

The other errors shows deprecated constant in PHP 8.1 after googling: https://www.php.net/manual/en/migration81.deprecated.php

Check it's location in your project and possibly remove/fix that as well, it might help too.
