que in rails should enable eager_loading

[joevandyk]

from sidekiq faq;

Rails has two features which are relevant here: eager loading and autoloading. Autoloading is only active in development mode and is not thread-safe so Sidekiq disables it and uses eager loading only. Eager loading loads your code only once when starting the server - it does not reload your code between jobs. If you have code located outside of the standard Rails directories (e.g. app/models, app/controllers, etc), Sidekiq will not see it unless you add the path to eager_load_paths in your Rails application configuration...

Just FYI @joevandyk @chanks recommend this is closed, as time has passed and Sidekiq no longer does this AFAICT for rails 5+. (see below for rationale).

Why doesn't Sidekiq autoload my Rails application code?
Sidekiq 4.2.0+ will reload code in Rails 5+ when running in development.

Sidekiq code now

There's an explicit pathway in the code for "# Rails 5+ && development mode, use Reloader".

        if ::Rails::VERSION::MAJOR < 4
          require 'sidekiq/rails'
          require File.expand_path("#{options[:require]}/config/environment.rb")
          ::Rails.application.eager_load!
        elsif ::Rails::VERSION::MAJOR == 4
          # Painful contortions, see 1791 for discussion
          # No autoloading, we want to force eager load for everything.
          require File.expand_path("#{options[:require]}/config/application.rb")
          ::Rails::Application.initializer "sidekiq.eager_load" do
            ::Rails.application.config.eager_load = true
          end
          require 'sidekiq/rails'
          require File.expand_path("#{options[:require]}/config/environment.rb")
        else
          # Rails 5+ && development mode, use Reloader
          require 'sidekiq/rails'
          require File.expand_path("#{options[:require]}/config/environment.rb")
        end

So I think this force eager-loading is only for pre v5 (maybe the intention was for 4.2.0+, but the code says 5+).

Cleaning up old issues. Yeah, I'm going to close this since it's old, people aren't really complaining about it and I don't think we should add any more Rails-specific logic unless it's really necessary (it's very difficult to test well).
