Symfony version(s) affected

6.3.5

Description

Working on dockerized project with shared prebuilt base image without PCNTL module enabled.

After updating to Symfony latest release 6.3.5 - the messenger:consume command no longer can be executed, it returns

In the latest release there is a fix for exiting messenger:failed:retry command, which introduces this implementation:

public function getSubscribedSignals(): array
    {
        return $this->signals ?? [\SIGTERM, \SIGINT];
    }

without checking if the signals are defined.

With symfony/messenger:6.3.4 there is no such problem.

According to PHP documentation:
Process Control support in PHP is not enabled by default. (https://www.php.net/manual/en/pcntl.installation.php)

How to reproduce

Run a Symfony 6.3.5 project with messenger configuration in an environment with php8.2, without pcntl extension.

Try to run php bin/console messenger:consume
