Problem

  • BlockManager always uses createInstance() instead of getInstance().

  • This means that BlockManager never knows whether it previously tried to instantiate a plugin and whether that failed.

  • When manually triggering a PHP notice in StaticReflectionParser, you get this:

    Notice: Undefined variable: className in Doctrine\Common\Reflection\StaticReflectionParser->parse() (line 122 of core\vendor\doctrine\common\lib\Doctrine\Common\Reflection\StaticReflectionParser.php).

I think I'm missing some context, can you show what you did in order to do this? I'm going to have trouble helping here until I know what you're doing to get these exceptions.

About half of this is #1892462: EntityManager should use the CacheDecorator, I'm hoping you borrowed the code and didn't do all of the same work.

I'd imagine you'll have the same issues with static caching I did.

One thought would be to introduce a public resetDefinitions() method on PluginManagerInterface, and PluginManagerBase::resetDefinitions() would just do $this->definitions = array();

Or expand clearCachedDefinitions() to handle that.

Not sure if anything here is still relevant, we have fallback plugins and we don't reparse plugins when one is missing AFAIK.
