[Validation][FrameworkBundle] Allow EnableAutoMapping to work without auto-mapping namespaces #34707

Currently, when no framework.validation.auto_mapping namespaces are configured, the EnableAutoMapping annotation has no effect on its own, because the loaders were removed by the fwb extension and the compiler pass.
Simply adding a namespace (even a foolish one) will make it work:

    validation:
        auto_mapping:
            '*': ~ # this does not really map anything, but allows `EnableAutoMapping` to work as loaders won't be removed.

So for those only wanting to use the auto-mapping feature by explicitly setting the EnableAutoMapping annotation, it'll be counter-intuitive, as it cannot work without declaring at least one namespace.

        // Fallback on the config
-        return null === $classValidatorRegexp || preg_match($classValidatorRegexp, $metadata->getClassName());
+        return null !== $classValidatorRegexp && preg_match($classValidatorRegexp, $metadata->getClassName());


⚠️ This is a BC break for the ones using the component directly:

before, setting $classValidatorRegexp to null would always consider the auto-mapping enabled for class by default

now, null will consider auto-mapping disabled for class by default, but can still be enabled by using EnableAutoMapping.

This needs a proper BC layer in any case, but I think the current way it works is not the most relevant. If you want it to be enabled by default for all classes, just use ".*". null should consider the auto-mapping feature not enabled for the class.

EDIT: see second commit

What about just doing the BC break? The trait is new to 4.4.0, let's handle this as a bug.

That's not about the trait actually. That's about 4.3 behavior of Doctrine/PropertyInfo loaders with a null regex. On 4.3 it was expected to enable the automapping with a null regex:

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

Lines 50 to 52 in bbda69d

if (null !== $this->classValidatorRegexp && !preg_match($this->classValidatorRegexp, $className)) {

return false;

}

Or do you mean handle this as a bug in 4.3?

/cc @dunglas WDYT?

see also #33828

this behavior already changed several times so... I'm in favor of introducing this change now, even if it's a real BC break (we'll have to document this in UPGRADE.md).

Could we clarify in Configuration (maybe with an ->info()) the valid values for auto_mapping and what they mean?

Pass an array to enable auto-mapping & activate it automatically for matching namespaces

Pass null to turn the auto-mapping feature on only and activate with config

The wording/explanation might be more clear if we (in this PR) add a proper enable/disable flag to this config. And maybe instead of auto_mapping: ~ we make it be auto_mapping: true.

ogizanagi · 2019-12-09T08:52:11Z

Alright, I've removed the BC layer and documented the BC break & alternative in CHANGELOG & UPGRADE files.

I'd suggest to:

allow to disable auto-mapping entirely by setting framework.validation.auto_mapping: false in another PR. It's not critical to me and could go in 5.1. Auto-mapping is for now enabled by default, services are loaded, but have no effect unless the EnableAutoMapping constraint is set, or a configured namespace matches.
backport ->info() and add ->example() in 4.3 configuration following @weaverryan's suggestion in [Validation][FrameworkBundle] Allow EnableAutoMapping to work without auto-mapping namespaces #34707 (comment)

Failure high is expected. First build is failing but does not seems related to these changes.
