Delegator not looking for aliases

[weierophinney]

Good morning,

I've the following configuration:

    // Container configuration
    'dependencies'      => [
        'invokables' => [
            CommandBus::class => SimpleCommandBus::class,
        ],
        'factories'  => [
            EventBus::class                  => EventBusFactory::class,
            EventStore::class                => EventStoreFactory::class,
            PhpVersionRepository::class      => PhpVersionEventStoreRepositoryFactory::class,
            PhpVersionCommandHandlers::class => PhpVersionCommandHandlersFactory::class,
        ],
        'delegators' => [
            CommandBus::class => [
                PhpVersionCommandBusDelegatorFactory::class
            ]
        ]
    ]

Problem is that when I get the Command::Bus service, the PhpVersionCommandBusDelegatorFactory isn't invoked.

However, the following works:

    // Container configuration
    'dependencies'      => [
        'invokables' => [
            CommandBus::class => SimpleCommandBus::class
        ],
        'factories'  => [
            EventBus::class                  => EventBusFactory::class,
            EventStore::class                => EventStoreFactory::class,
            PhpVersionRepository::class      => PhpVersionEventStoreRepositoryFactory::class,
            PhpVersionCommandHandlers::class => PhpVersionCommandHandlersFactory::class,
        ],
        'delegators' => [
            SimpleCommandBus::class => [
                PhpVersionCommandBusDelegatorFactory::class
            ]
        ]
    ]

Why there is no alias matching there?

Hello @nuxwin,

I believe the answer is in the following lines:

https://github.com/laminas/laminas-pimple-config/blob/master/src/Config.php#L112 https://github.com/laminas/laminas-pimple-config/blob/master/src/Config.php#L135

In the invokables config array if the key does not match the invokable FQCN the key is used as an alias, so in your first example the delegator factories are not called as their key does not match the actual service id (FQCN: SimpleCommandBus::class), bit its alias CommandBus::class

kind regards
