Description

This code is generated by DI and cause ClassNotFoundException for me:

<?php

namespace ContainerSF7xQsW;

use Symfony\Component\DependencyInjection\Argument\RewindableGenerator;
use Symfony\Component\DependencyInjection\Exception\RuntimeException;

/**
 * @internal This class has been auto-generated by the Symfony Dependency Injection Component.
 */
class getMailer_TransportFactory_NativeService extends App_KernelDevDebugContainer
{
    /**
     * Gets the private 'mailer.transport_factory.native' shared service.
     *
     * @return \Symfony\Component\Mailer\Transport\NativeTransportFactory
     */
    public static function do($container, $lazyLoad = true)
    {
        include_once \dirname(__DIR__, 4).'/vendor/symfony/mailer/Transport/TransportFactoryInterface.php';
        include_once \dirname(__DIR__, 4).'/vendor/symfony/mailer/Transport/AbstractTransportFactory.php';
        include_once \dirname(__DIR__, 4).'/vendor/symfony/mailer/Transport/NativeTransportFactory.php';

        $a = ($container->services['event_dispatcher'] ?? self::getEventDispatcherService($container));

        if (isset($container->privates['mailer.transport_factory.native'])) {
            return $container->privates['mailer.transport_factory.native'];
        }

        return $container->privates['mailer.transport_factory.native'] = new \Symfony\Component\Mailer\Transport\NativeTransportFactory($a, ($container->privates['.debug.http_client'] ?? self::get_Debug_HttpClientService($container)), ($container->services['monolog.logger.mailer'] ?? $container->get('monolog.logger.mailer', ContainerInterface::NULL_ON_INVALID_REFERENCE)));
    }
}

And the exception is:
Attempted to load class "ContainerInterface" from namespace "ContainerSF7xQsW". Did you forget a "use" statement for e.g. "Symfony\Component\DependencyInjection\ContainerInterface" or "Psr\Container\ContainerInterface"?

The PhpDumper does generates wrong code:

symfony/src/Symfony/Component/DependencyInjection/Dumper/PhpDumper.php

Line 2058 in de3d115

$code = sprintf('$container->get(%s, ContainerInterface::NULL_ON_INVALID_REFERENCE)', $this->doExport($id));

This patch cause the regression: 16fcdda

How to reproduce

To be honest, I don't know how to reproduce this. I also don't fully understand why it only happened to me and not to others.

Possible Solution

Either of the two example codes will generate working code.

$code = sprintf('$container->get(%s, \\%s::NULL_ON_INVALID_REFERENCE)', $this->doExport($id), ContainerInterface::class);

or

$code = sprintf('$container->get(%s, \Symfony\Component\DependencyInjection\ContainerInterface::NULL_ON_INVALID_REFERENCE)', $this->doExport($id));

Additional Context

No response

Looks like the PHP dumper has been updated to reference the constant but without adding the corresponding use statement in the generated code.

Can you please confirm that #52597 fixes the issue?

[connorhu]

@nicolas-grekas Yes it does fix the issue.

@nicolas-grekas I guess you missed that this bug exists since 6.0, so it's not enough to fix it only in the 7.0 branch.
