Symfony version(s) affected: >= 4.4

Description
DoctrineExtension#loadValidatorLoader registers the DoctrineLoader as a service. This class uses the Symfony\Component\Validator\Mapping\Loader\AutoMappingTrait which might not be available.

As soon as this service gets autloaded at container build time* this will produce a fatal error under PHP8.1:

PHP Fatal error:  During class fetch: Uncaught ReflectionException: Class "Symfony\Component\Validator\Mapping\Loader\AutoMappingTrait" not found while loading "Symfony\Bridge\Doctrine\Validator\DoctrineLoader`

*) one scenario is for instance reading class annotations/attributes and thereby calling $container->getReflectionClass()

How to reproduce

  1. Set up a Sf application with doctrine-bundle installed.
  2. Add a compiler pass that does the following: 
    foreach ($container->getDefinitions() as $definition) {
  $container->getReflectionClass($definition->getClass(), false);
}
  3. Build the container.

This reminded me a bit of #32395. 🙂 Maybe we could mark the service as synthetic if the AutoMappingTrait is not available or register a dummy instead?

Registering a service with a class that cannot be autoloaded is fine in general, as long as you don't wire it. If you think that this service should not be registered at all, please open an issue here: https://github.com/doctrine/DoctrineBundle/issues

If you think that this is a bug of the DependencyInjection component, you're in the right place, however. 🙂

You're right I guess. 🙂 My brain was probably assuming that the extension was part of the symfony/doctrine-bridge as well.
I'm going to open up an issue over at DoctrineBundle.

Though you could argue that the bridge then should either require its dependencies or tolerate missing them? (Not easy with traits, unfortunately.)

The latter is the case. The bridge is a collection of glue code for various Symfony components. If we made all dependencies mandatory, the bridge would pull a lot of components that you probably don't use. The alternative would be that we have a symfony/form-doctrine-bridge, a symfony/validator-doctrine-bridge, a symfony/uid-doctrine-bridge and so on. We would end up micro-managing tiny packages.

To me it looks like symfony/validator does not seem to be needed for the DoctrineLoader class - other than for the trait.

It's just a few lines. Wdyt about pulling the code in to make it more resilient?

symfony/src/Symfony/Component/Validator/Mapping/Loader/AutoMappingTrait.php

Lines 24 to 33 in e1b81e3

private function isAutoMappingEnabledForClass(ClassMetadata $metadata, string $classValidatorRegexp = null): bool
{
// Check if AutoMapping constraint is set first
if (AutoMappingStrategy::NONE !== $strategy = $metadata->getAutoMappingStrategy()) {
return AutoMappingStrategy::ENABLED === $strategy;
}
// Fallback on the config
return null !== $classValidatorRegexp && preg_match($classValidatorRegexp, $metadata->getClassName());
}

That is not correct. The class implements LoaderInterface which also comes from this package. And honestly, without the validator, the whole class is pretty much useless.

Let's fix this over at DoctrineBundle then.

I don't use Validator component in my project but this issue hits me, looks like the loader is loaded anyway.

Bumping up doctrine/doctrine-bundle to v2.4.3 helped me.
