Disable Events

Experimenting

<?php

declare(strict_types=1);

namespace Drupal\custom_migration;

use Drupal\Core\DependencyInjection\ContainerBuilder;
use Drupal\Core\DependencyInjection\ServiceProviderBase;

/**
 * Defines a service provider for the custom_migration module.
 *
 * @see https://www.drupal.org/node/2026959
 */
final class CustomMigrationServiceProvider extends ServiceProviderBase {

  /**
   * {@inheritdoc}
   */
  public function alter(ContainerBuilder $container): void {
    if ($container->hasDefinition('flag.count')) {
      $container->removeDefinition('flag.twig.count');
      $container->removeDefinition('flag.count');
    }
  }

}

This came from #2409901-14: Implement Migration Paths for Flag 7.x →

We will have to do something like this for hooks in 11.1 too so this is great.

Oh yeah, I was thinking that too, though is that hooks are events now?

The above code works in #2 BTW, just need to remember to uninstall the migration module after the migration, hence a better place would be here...

Do we have access to config inside a custom MigrateBoostServiceProvider class?

They are event listeners, we need to make sure this only takes effect during migration and rebuild the container after.

Do we have access to config inside a custom MigrateBoostServiceProvider class?

Not sure

We should be able to access it the same way we do in settings though I think.

Got some advice from @ghostofdrupalpast.

I think it might be better to decorate module handler and add a method to check config and another to check if a migration is running.

Then it's not tied as closely to drush and we don't have to worry as much about rebuilding containers.

Actually I'm realizing we are talking about two different features, I'll open an issue for mine.
