Could not process [path] file, due to: Undefined constant

[escopecz]

Dear Rector community,

we are preparing support for PHP 8.0 in Mautic and the Rector v0.12.22 is passing on PHP 7.4 but failing on PHP 8.0 with error message:

Could not process "app/bundles/EmailBundle/EventListener/ReportSubscriber.php" file, due to: "Undefined constant "Mautic\EmailBundle\EventListener\MAUTIC_TABLE_PREFIX". On line: 72

We cannot understand why when looking at the file on that line:

https://github.com/mautic/mautic/blob/4.3/app/bundles/EmailBundle/EventListener/ReportSubscriber.php#L72

This "fix" made the CI pass but it's not optimal:

mautic/mautic@e3768d2

Can anyone give us some pointers about why is it failing and what would be the correct fix?

Hi Honza,

there have been many new releases of PHPStan 1.7.* that handles magical autoloading in different way.
Make sure to upgrade to the latest PHPStan 1.7.10 and Rector 0.13.4 first.

You can define your own bootstrap file instead of define it in the rector.php, so you can configure:

    // do you need to include constants, class aliases or custom autoloader? files listed will be executed
    $rectorConfig->bootstrapFiles([
        __DIR__ . '/bootstrap.php',
    ]);
