count_introspection_fields for max_complexity

[jstrojil]

Currently, count_introspection_fields is only supported for max_depth.

Also, overriding complexity calculation doesn't work for introspection, it seems that this is never called.

      def calculate_complexity(query:, nodes:, child_complexity:)

Would be nice to find a way how to support both, max_depth and max_complexity.

Thanks a lot

Hey, thanks for reporting this. I agree that complexity should handle introspection similar to depth. I'm not sure why that method is skipped for introspection fields... I would have guessed that it worked the same as anything else!

Feel free to take a try at addressing this if you have time before I do, otherwise, I'll follow up here after I make time to investigate.

Hey, I added that new option, in #4939.

Also, I added a spec for complexity_for in 3afe931. It "works" -- but you have to set up your base field class using field_class. Also, I discovered some weirdness where you have to use GraphQL::Schema::LateBoundType.new(...) in order to use the built-in types from GraphQL-Ruby. If you reference them directly, it doesn't work.

I hope one of those options works for you -- please let me know if it doesn't!
