Rails core - Jul 2011 - "app/controllers" added twice in load_paths

Hi,

I am trying to understand rails initialization process. While doing this I
came across following code snippet in "
https://github.com/rails/rails/blob/v2.3.8/railties/lib/initializer.rb"
file


I am not getting why "app/controllers" have been added twice in
load_paths.
Is there any specific reason behind it?

def default_load_paths
        paths = []

        # Add the old mock paths only if the directories exists
        paths.concat(Dir["#{root_path}/test/mocks/#{environment}"]) if
File.
exists?("#{root_path}/test/mocks/#{environment}")

        # Add the app''s controller directory
        *paths.concat(Dir["#{root_path}/app/controllers/"])*

        # Followed by the standard includes.
        paths.concat %w(
             app
             app/metal
             app/models
*             app/controllers*
             app/helpers
             app/services
             lib
             vendor
).map { |dir| "#{root_path}/#{dir}" }.select { |dir|
File.directory?(dir) }

        paths.concat builtin_directories
end

Thanks and Regards,
Chirag Viradiya
