Bug #14083: Refinement in block calling incorrect method

• Status: Open
• Priority: Normal
• Assignee: -

• Backport: 2.3: UNKNOWN, 2.4: UNKNOWN

[bjfish (Brandon Fish)]

Tested on ruby versions 2.3.4 and 2.4.1

When a refinement is used inside a block, the scope of the refinement is not ending when the block has ended. The following example illustrates the issue:

Example:

class Example
  def test
    puts "Example#test"
  end
end

module M1
  refine Example do
    def test
      puts "Example#test in M1"
    end
  end
end

module M2
  refine Example do
    def test
      puts "Example#test in M2"
    end
  end
end

e = Example.new
[M1, M2].each { |r| 
  e.test
  using r
  e.test 
}

Actual Output

Example#test
Example#test in M1
Example#test in M1
Example#test in M2

Expected output

Example#test
Example#test in M1
Example#test
Example#test in M2
