Symfony2 stop Composer installing parameters.yml.dist into parameters.yml

Question

New in symfony 2.3 the composer install script also copies the parameters.yml.dist file contents into the parameters.yml file, explain

Answer 1

First solution : add "keep-outdated": true in the 'extra' section of your composer.json.

[...]
"extra": {
    "symfony-app-dir": "app",
    "symfony-web-dir": "web",
    "incenteev-parameters": {
        "file": "app/config/parameters.yml",
        "keep-outdated": true  <------------ ADDED LINE ------------
    },
    "branch-alias": {
        "dev-master": "2.3-dev"
    },
    "symfony-assets-install": "symlink"
}
[...]

incenteev will not remove parameters any more.

Second solution : modify the app/config/parameter.yml.dist file. For me it was to add Sqlite parameters 'path' and 'memory' and avoid to see them deleted each time I do a composer update.

# app/config/parameter.yml.dist
parameters:
    database_driver:   pdo_sqlite
    database_host:     ~
    database_port:     ~
    database_name:     ~
    database_user:     ~
    database_password: ~
    database_path:     ~ <------------ ADDED LINE ------------
    database_memory:   ~ <------------ ADDED LINE ------------
[...]

I don't know which solution is the best but both works.
