what about passing a non-default store as optional 3rd arg in lock()? and avoid this state issue.

meaning the user injects his own store if needed

If that's the case then this change wouldn't be needed because you can implement the Symfony\Component\Lock\Factory service in a command by dependency injection to create locks.

Right ... the user can also set private $store; already.Then, im not sure what we're solving here 🤔

We should favor pure DI / service usage IMHO.

I'm trying to solve a configurable store that can be used in commands, this can either be done by:

  • The current solution (setStore in LockableTrait);
  • Implementing a default store in Symfony\Component\Console\Command\Command;
  • Writing a LockableCommand class which basically does what LockableTrait does now, so this could mean bye bye for LockableTrait - would also mean more abstraction;

Why?

Because currently LockableTrait is limited to SemaphoreStore and FlockStore. Also you can use dependency injection but that would mean that you have to overwrite the constructor. Last, it's not configurable as in available in a command by default.

Is that a real problem? IMHO it's the explicit way.. compared to calling an arbitrary setStore method. At least i agree with https://github.com/symfony/symfony/pull/31914/files#r294103123; if we do this we should add a marker interface for it.

I agree that we should be using a marker interface. I've updated the PR.

I'm a bit unsure about injecting the store based on method existence.
This is about autoconfiguration which usually works on types, and traits are not types. Should we add a marker LockableInterface and use it as a type for ContainerBuilder::registerForAutoconfiguration()?

$definition->addMethodCall('setStore', [$container->getDefinition($storeDefinition)]);
}
}
}
