Installation broken via composer create-project

[leofeyer]

We should run the Incenteev script handler at the end (or our handlers first).

[dtomasi]

I tried a few different orders, but it´s still not working.

If parameters.yml does not exist when Contao\CoreBundle\Composer\ScriptHandler::addDirectories is called, it will throw an Exception as well.

I think this happens because Contao\CoreBundle\Command\InstallCommand is a ContainerAwareCommand and uses parameters. So at this point Symfony will load config.yml which tries to import the non existing parameters.yml on top.

[leofeyer]

I have adjusted the order of the Composer script handlers in e8e64c1. Together with contao/core-bundle@f02f9ac this should solve the issue. Can you please confirm?

[dtomasi]

Looks like the ContainerAwareCommand wasn´t the problem. There is still a RuntimeException.

composer create-project contao/standard-edition contao4 @dev -vvv

I found the problem: the console commands are initializing the Contao 3 framework and the Contao 3 framework triggers the Automator::generateSymlinks() method. I will remove this call from the listener.

@contao/developers Do we really want to initialize the Contao 3 framework on the console?

[leofeyer]

Changed in b0f82c6. @dtomasi Please wait a few minutes until packagist has updated its cache and then try again. Thanks for your help.

[dtomasi]

+1 This works perfectly! Thank you!

[aschempp]

I thought we do need the framework for our Automator tasks?

[leofeyer]

@aschempp Actually we should be able to decide on a per command basis. Similar to extending ContainerAware there should be a FrameworkDependendCommand or something alike.

[discordier]

I agree, we should limit the initialization to commands that need the framework.

But please not by extending a command class but by implementing an interface.

[leofeyer]

But how is the event listener supposed to know about it?

[dtomasi]

Maybe this could be done by ConsoleEvents::COMMAND.
with something like this:

use Symfony\Component\Console\Event\ConsoleCommandEvent;
use Symfony\Component\Console\ConsoleEvents;

    public function isFrameworkDependendCommand(ConsoleCommandEvent $event) {

        $ref = new ReflectionClass($event->getCommand());
        if ($ref->implementsInterface('FrameworkDependentCommand')) {
            // Initialize Framework and maybe inject it
        }
    }

PS.: @leofeyer nice pic ;-)

see: https://github.com/ContaoBlackforest/core-bundle/commit/5456510d8e94b88f1c4605b7d3c47f64a97d6d1f

[leofeyer]

As discussed on Mumble on March, 26th:

• The interface should be called Contao\Command\ContaoFrameworkDependentInterface.
• Discuss the comments in your PR (ContaoBlackforest/core-bundle@5456510d8e94b88f1c4605b7d3c47f64a97d6d1f)
• We need to add a $this->booted so the Contao framework is not booted twice.

[dtomasi]

The interface should be called Contao\Command\ContaoFrameworkDependentInterface.

Isn´t it Contao\CoreBundle\Command\ContaoFrameworkDependentInterface?

[Toflar]

Isn´t it Contao\CoreBundle\Command\ContaoFrameworkDependentInterface?

Of course :)

[dtomasi]

Whats about the $this->booted? Should we create a static privat $isBooted?

[Toflar]

Whats about the $this->booted? Should we create a static privat $isBooted?

Yeah but @leofeyer will do :P

[dtomasi]

Ok, should I do a PR of the current state??

[leofeyer]

Closed in favor of the PR (contao/core-bundle#159). @dtomasi Thanks a lot for your help :)
