We probably need to deprecate using options in this Compound abstract class first, to be able to remove support properly.

Indeed, that's not a really useful feature anymore. I'm gonna send a PR for the deprecation targeting the 7.4 branch.

-    {
-        return 'constraints';
+        parent::__construct(null, $groups, $payload);
    }

    protected function getCompositeOption(): string


this method should also be removed, as it does not make sense anymore once the parent does not handle an array of options anymore.

getCompositeOption() is used independently from the $options array in the constructor of the Composite base class:

symfony/src/Symfony/Component/Validator/Constraints/Composite.php

Lines 64 to 115 in b49a855

foreach ((array) $this->getCompositeOption() as $option) {

/** @var Constraint[] $nestedConstraints */

$nestedConstraints = $this->$option;

if (!\is_array($nestedConstraints)) {

$nestedConstraints = [$nestedConstraints];

}

foreach ($nestedConstraints as $constraint) {

if (!$constraint instanceof Constraint) {

if (\is_object($constraint)) {

$constraint = get_debug_type($constraint);

}

throw new ConstraintDefinitionException(\sprintf('The value "%s" is not an instance of Constraint in constraint "%s".', $constraint, get_debug_type($this)));

}

if ($constraint instanceof Valid) {

throw new ConstraintDefinitionException(\sprintf('The constraint Valid cannot be nested inside constraint "%s". You can only declare the Valid constraint directly on a field or method.', get_debug_type($this)));

}

}

if (!isset(((array) $this)['groups'])) {

$mergedGroups = [];

foreach ($nestedConstraints as $constraint) {

foreach ($constraint->groups as $group) {

$mergedGroups[$group] = true;

}

}

// prevent empty composite constraint to have empty groups

$this->groups = array_keys($mergedGroups) ?: [self::DEFAULT_GROUP];

$this->$option = $nestedConstraints;

continue;

}

foreach ($nestedConstraints as $constraint) {

if (isset(((array) $constraint)['groups'])) {

$excessGroups = array_diff($constraint->groups, $this->groups);

if (\count($excessGroups) > 0) {

throw new ConstraintDefinitionException(\sprintf('The group(s) "%s" passed to the constraint "%s" should also be passed to its containing constraint "%s".', implode('", "', $excessGroups), get_debug_type($constraint), get_debug_type($this)));

}

} else {

$constraint->groups = $this->groups;

}

}

$this->$option = $nestedConstraints;

}

The important part when not being able anymore to use the options array is that the property/properties referenced with getCompositeOption() are initialised in child class before the base constructor is called (that's part of the upgrade/changelog files).

Wow, such nice diff! Thanks for working on this!

in cases like this, we still have a legacy $options argument
would it make sense to try to remove it, using some BC layer?
or should we throw to be sure passing anything else than null is forbidden?

We cannot easily detect if options are passed when changing the order of arguments in 7.4 (we can try again in 8.1). But I added checks for $options to be null and throw otherwise.

I'm wondering about how we could remove those $options arguments, but let's figure this out later (if there's a simple enough way)
About Choice, I made a comment in #61255, no blocker for this one.
Thanks for tackling this!
