Container inlining issue

[l-you]

Consider following example

use App\GraphQL\Service\RequestService;
use Overblog\GraphQLBundle\Annotation\Mutation;
use Overblog\GraphQLBundle\Annotation\Provider;
use Overblog\GraphQLBundle\Annotation\Query;
use Overblog\GraphQLBundle\Definition\Resolver\QueryInterface;

#[Provider]
class TestProvider implements QueryInterface
{
    public function __construct(private readonly RequestService $requestService)
    {
    }

    #[Query(name: 'ssss')]
    public function getSomething(int $amount, bool $yes = true): string
    {
        return 'Hello world!'.$amount.' '.($yes ? '+' : '-').$this->requestService->getCurrentClientIp();
    }

    #[Mutation(name: 'ssm')]
    public function doSom(int $amount, bool $yes = true): string
    {
        return 'Hello mut!'.$amount.' '.($yes ? '+' : '-');
    }
}

overblog_graphql:
  security:
    enable_introspection: true
  definitions:
    schema:
      query: RootQuery
      mutation: RootMutation
      # the name of extra types that can not be detected
      # by graphql-php during static schema analysis.
      # These types names should be explicitly declare here
      types: [ ]
    mappings:
      types:
        - type: attribute
          dir: "%kernel.project_dir%/src/GraphQL"
          suffix: ~

Issue is I'm getting error that says The "App\GraphQL\TestProvider" service or alias has been removed or inlined when the container was compiled. You should either make it public, or stop using the container directly and use dependency injection instead.

Resolver in RootQueryType in cache directory looks like following:

'resolve' => function ($value, $args, $context, $info) use ($services) {
        return $services->get('container')->get("App\\GraphQL\\TestProvider")->getSomething(...$services->get('container')->get('overblog_graphql.arguments_transformer')->getArguments(["amount" => "Int!", "yes" => "Boolean"], $args, $info));
    },

RootQuery looks like this.

declare(strict_types=1);

namespace App\GraphQL\Types;

use Overblog\GraphQLBundle\Annotation\Type;

#[Type]
final class RootQuery
{
    public function __construct()
    {
    }
}

Any suggestion how to make it work?

Hi @rusted-love
Sorry for the late reply. The problem is that App\GraphQL\TestProvider must be a public registered service in the container.
So, in your services.yaml file, you should have something like this:

App\GraphQL\TestProvider:
    public: true

Also, your providers don't need to extend QueryInterface.

But why library does not provide some kind if compiled container?
With Symfony router I do not need to make services public.

I guess we could. I'll look into it when I'll have a bit of time.

Hi! I had a quick look at this, in a very simple playground project, I have this generated type:

<?php

namespace GraphQL\AutoGeneratedDefinitions;

use GraphQL\Type\Definition\ObjectType;
use GraphQL\Type\Definition\Type;
use Overblog\GraphQLBundle\Definition\ConfigProcessor;
use Overblog\GraphQLBundle\Definition\GraphQLServices;
use Overblog\GraphQLBundle\Definition\Resolver\AliasedInterface;
use Overblog\GraphQLBundle\Definition\Type\GeneratedTypeInterface;

/**
 * THIS FILE WAS GENERATED AND SHOULD NOT BE EDITED MANUALLY.
 */
final class QueryType extends ObjectType implements GeneratedTypeInterface, AliasedInterface
{
    public const NAME = 'Query';
    
    public function __construct(ConfigProcessor $configProcessor, GraphQLServices $services)
    {
        $config = [
            'name' => self::NAME,
            'fields' => fn() => [
                'hello' => [
                    'type' => Type::nonNull(Type::string()),
                    'resolve' => function ($value, $args, $context, $info) use ($services) {
                        return $services->get('container')->get("App\\Query\\Hello")->hello(...$services->get('container')->get('overblog_graphql.arguments_transformer')->getArguments(["name" => "String"], $args, $info));
                    },
                    'args' => [
                        [
                            'name' => 'name',
                            'type' => Type::string(),
                            'defaultValue' => 'World',
                        ],
                    ],
                ],
            ],
        ];
        
        parent::__construct($configProcessor->process($config));
    }
    
    /**
     * {@inheritdoc}
     */
    public static function getAliases(): array
    {
        return [self::NAME];
    }
}

I think the quickest way to solve this issue would be to register the GraphQL services into the GraphQLServices locator, so we can go from $services->get('container')->get("App\\Query\\Hello") to $services->get("App\\Query\\Hello")

But maybe we can go one step further and generate something like this instead:

<?php

namespace GraphQL\AutoGeneratedDefinitions;

use GraphQL\Type\Definition\ObjectType;
use GraphQL\Type\Definition\Type;
use Overblog\GraphQLBundle\Definition\ConfigProcessor;
use Overblog\GraphQLBundle\Definition\GraphQLServices;
use Overblog\GraphQLBundle\Definition\Resolver\AliasedInterface;
use Overblog\GraphQLBundle\Definition\Type\GeneratedTypeInterface;

/**
 * THIS FILE WAS GENERATED AND SHOULD NOT BE EDITED MANUALLY.
 */
final class QueryType extends ObjectType implements GeneratedTypeInterface, AliasedInterface
{
    public const NAME = 'Query';
    
    public function __construct(
        ConfigProcessor $configProcessor, 
        App\Query\Hello $service0,
        ArgumentsTransformer $argumentTransformer,
    ) {
        $config = [
            'name' => self::NAME,
            'fields' => fn() => [
                'hello' => [
                    'type' => Type::nonNull(Type::string()),
                    'resolve' => static fn ($value, $args, $context, $info)
                        => $service0->hello(...$argumentTransformer->getArguments(["name" => "String"], $args, $info)),
                    'args' => [
                        [
                            'name' => 'name',
                            'type' => Type::string(),
                            'defaultValue' => 'World',
                        ],
                    ],
                ],
            ],
        ];
        
        parent::__construct($configProcessor->process($config));
    }
    
    /**
     * {@inheritdoc}
     */
    public static function getAliases(): array
    {
        return [self::NAME];
    }
}

It should let the SymfonyContainer do more optimization at compile time and improve performances a bit.

wdyt?

Depending on how much work this represents, I can take a look at it in the next weeks
