Question

I would like to retrieve the password currently used by a doctrine2 dbal connection, in symfony2.

If I use $kernel->getContainer()->getParameter('database_password'), I can find the one defined in parameters.yml but if I define different password for some environments (in config_test.yml for example), the data from parameters.yml is useless.

Now if I look thru $kernel->getContainer()->getParameterBag()->all(), I still cannot find it.

And in case you wonder why? I am using a lock mechanism in a function, and I am trying to use register_shutdown_function() to remove that lock in case there is a fatal error, using php built-in mysql or pdo function since at that point, most of the framework is down.

If you cannot retrieve it, then you will not have a DB connection either.

Parameters from test environment won’t be loaded in the dev, prod, … environment!
In case of overriding, define all your connection parameters in parameters.yml

//parameters.yml
database_prod_name: prod
database_prod_user: prod_user
database_prod_password: prod_password

database_dev_name: dev
database_dev_user: dev_user
.....

//config_prod.yml
doctrine:
    dbal:
        dbname:   "%database_prod_name%"
        user:     "%database_prod_user%"
        password: "%database_prod_password%"
....

Same goes for all other environments your using.
