Hi all!
I need to store the lock state in Couchbase DB.

I implemented the Symfony\Component\Lock\PersistingStoreInterface as class App\Lock\CouchbaseStore. Now I need to connect it to my app.
I looked here \Symfony\Bundle\FrameworkBundle\DependencyInjection\FrameworkExtension::registerLockConfiguration and here \Symfony\Bundle\FrameworkBundle\DependencyInjection\Configuration::addLockSection but I didn't understand how to connect it to mine app. For example, can I redefine \Symfony\Component\Lock\Store\StoreFactory in a DI container or something else?

Hi 👋

You can inject your CouchbaseStore in a LockFactory service and directly use it; no need to bother with the StoreFactory (unless you want to propose your implementation to Symfony!)

I thought about it. How will the env variable work with this solution?

###> symfony/lock ###
# Choose one of the stores below
# postgresql+advisory://db_user:db_password@localhost/db_name
LOCK_DSN=flock
###< symfony/lock ###

Can I replace the lock.factory alias in DI container with my own?
Like this

$services->set('lock.factory', LockFactory::class)->args([CouchbaseStore::class]);

You won’t need the env var in your case as you won’t use the FrameworkBundle’s integration. You can even disable it:

framework:
    lock:
        enabled: false
        default: whatever # see https://github.com/symfony/symfony/pull/48119

Then indeed you can create the LockFactory service yourself:

$services->set(LockFactory::class)->arg('$store', new Reference(CouchbaseStore::class));

Thanks for your help!
I didn``t know about enabled: false.
Now I solved my task.
