Question

I just testing new features on symfony 2.1-BETA3. Few hours ago BETA4 has been released but I don’t know how to update BETA3 to BETA4 using composer. In 2.0.x release notes Fabien said:

If you already have a project based on the Symfony Standard Edition 2.0.x, you can easily upgrade to 2.0.15 by getting the new deps and deps.lock files.

Have I replace my composer.lock file? What about my own requires like:

"package": "stof/doctrine-extensions-bundle",
"version": "dev-master",
"source-reference": "36356b158b74cb68f96dc0b657e8732422b9d5dd",
"commit-date": "1341954345"

Answer 1

Don’t touch composer.lock! Change composer.json. If you are using the standard edition, you probably already have something like

"symfony/symfony": "2.1.*"

and

"minimum-stability": "dev"

in there. The later one means, that you allow dev packages to get installed. The first one means, that you want any 2.1.* version. You can change it to

"symfony/symfony": "2.1.0-BETA4"

if you want, but the original 2.1.* should be suffice right now. Now call

php composer.phar update

This will update composer.lock too. Now you maybe must call (must say: I’ve forgotten it) call

php composer.phar install

to install the dependencies from composer.lock.

In short:

# To install (maybe even after update)
$ php composer.phar install
# To update 
$ php composer.phar update
# To add, remove or change dependencies
# edit composer.json
$ php composer.phar update

YOu never need to touch composer.lock yourself and you shouldn’t to avoid side effects of composer.
