CraftVariable::EVENT_INIT event not working in modules since 3.0.5

[Wiejeben]

Description

After updating to 3.0.5, \craft\web\twig\variables\CraftVariable::EVENT_INIT stopped working inside my module, reverting back to 3.0.4 fixes this.

I have a feeling it might be broken because of this change:

610f7ac#diff-d735858371e00b6108b199120931723f

Steps to reproduce

1. Make sure you are running 3.0.5.
2. Add the following inside your (__construct() or) init() method inside your module that is being loaded on bootstrap:

// Register template variables
\yii\base\Event::on(
    \craft\web\twig\variables\CraftVariable::class,
    \craft\web\twig\variables\CraftVariable::EVENT_INIT,
    function(\yii\base\Event $event) {
        die('It won\'t');
    }
);

3. Nothing happens.

Additional info

• Craft version: 3.0.5
• PHP version: 7.0.10

Working on my end. Do you have any plugins installed?

[Wiejeben]

Ah right, I disabled all my plugins and noticed that fixed the error. Will be looking into the plugin that is causing the CraftVariable::EVENT_INIT to break.

[brandonkelly]

Most likely it’s because a plugin is actually loading Twig. If you can figure out which one, I can look into a better solution on my end.

[Wiejeben]

Right, I did some more debugging.

SEOmatic does some stuff right after Plugins::EVENT_AFTER_LOAD_PLUGINS is triggered. At one point \craft\web\View::renderObjectTemplate is called, which ends up initialising CraftVariable. Because Plugins::EVENT_AFTER_LOAD_PLUGINS gets triggered before the modules are bootstrapped, I never get to catch the CraftVariable initialisation.

Happy to make whatever changes make sense. This is something I struggled with as well, where other plugins would be doing something with Twig, and it caused all sorts of havoc. That's why I do the bulk of my initialization in Plugins::EVENT_AFTER_LOAD_PLUGINS

As of the next release, plugins will be loaded before modules once again, but in a way that maintains the fix for #2761.
