Issue #9452 has been updated by Shugo Maeda.

Status changed from Open to Closed
% Done changed from 0 to 100

Applied in changeset r44931.

----------
* vm_insnhelper.c (vm_call_method): should check ci->me->flag of
  a refining method in case the method is private.
  [ruby-core:60111] [Bug #9452]

* vm_method.c (make_method_entry_refined): set me->flag of a refined
  method entry to NOEX_PUBLIC in case the original method is private
  and it is refined as a public method.  The original flag is stored
  in me->def->body.orig_me, so it's OK to make a refined method
  entry public.  [ruby-core:60111] [Bug #9452]

* test/ruby/test_refinement.rb: related tests.

Bug #9452: Refining methods that should be private
https://bugs.ruby-lang.org/issues/9452#change-45109

* Author: Jan Lelis
* Status: Closed
* Priority: Normal
* Assignee: Shugo Maeda
* Category: 
* Target version: 
* ruby -v: ruby 2.2.0dev (2014-01-25 trunk 44707) [x86_64-linux]
* Backport: 1.9.3: UNKNOWN, 2.0.0: UNKNOWN, 2.1: UNKNOWN
----------------------------------------
Are refinements also meant to add private methods? This is what I tried:

    module R
      refine Object do
        def m
          puts "Success!"
        end

        private(:m)
      end
    end

    using R

    m # success
    42.m # success (= not private)


However, I can get near the desired functionality by defining a private method first:

    class Object
      private
      def m
      end
    end

    module R
      refine Object do
        def m
          puts "Success!"
        end
      end
    end

    using R
    m # success
    42.m # no success (= it is private)

It calls the right code. But requires global core ext.
