PDO Session Handler service is non-existent

[ghost]

I have set up the ClankBundle. I want to initialize session management so, I can have session object attached to the connections. I did what was suggested in the documentation. Added a service, attached it to framework session and clank handler. But when I run, php app/console clank:server it throws an error:

My services.yml file:

  services:
        session.handler.pdo:
            class:     Symfony\Component\HttpFoundation\Session\Storage\Handler\PdoSessionHandler
            public:    false
            arguments:
                - "mysql:dbname=%database_name%"
                - { db_username: %database_user%, db_password: %database_password% }

        kernel.listener.clank.client_event:
            class: Acme\ChatBundle\EventListener\AcmeClientEventListener
            tags:
                - { name: kernel.event_listener, event: clank.client.connected, method: onClientConnect }
                - { name: kernel.event_listener, event: clank.client.disconnected, method: onClientDisconnect }
                - { name: kernel.event_listener, event: clank.client.error, method: onClientError }

My config.yml file:

    imports:
        - { resource: parameters.yml }
        - { resource: security.yml }
        - { resource: services.yml }

        session_handler: session.handler.pdo
        topic:
            -
                name: "acme" #Important! this is the topic namespace used to match to this service!
                service: "acme_topic"

It is to be noted that the session handler works fine with in-browser app. It sets and gets session as expected. It is also reflected by changes in the table.

I've got the same problem, have you find a solution?

This is not the same bundle but the configuration of session handler is the same

https://github.com/GeniusesOfSymfony/WebSocketBundle/blob/master/Resources/docs/SessionSetup.md#symfony-pdo-session-handler

[yescardmen]

Thanks a lot, working like a charm.

Any luck with this issue I tried the configuration from https://github.com/GeniusesOfSymfony/WebSocketBundle/blob/master/Resources/docs/SessionSetup.md#symfony-pdo-session-handler and it is not working either. Can someone help me ? Thanks
