Issue #4994 has been updated by Sylvain Viart.


Fixed DelegateClass with method_missing(), somewhat ugly right?


<pre>
require 'delegate'

def hello
    :hello
end

class MyInt < DelegateClass(Integer)
    def initialize(value)
        @i = value
        super(@i)
        # I want some toplevel here
        @hello = hello()
    end

    def method_missing(m, *args, &block)
        if __getobj__.respond_to?(m)
            __getobj__.__send__(m, *args, &block)
        else
            Object.send(m, *args, &block)
        end
    end
end

ii = MyInt.new(2)
puts p"should call Integer#to_si: #{ii}"
puts "ii.class=#{ii.class}"
</pre>

output ruby 1.9.2p180 (2011-02-18 revision 30909) [x86_64-linux]
<pre>
should call Integer#to_si: 2
ii.class=MyInt

Bug #4994: DelegateClass don't find extern global public method in 1.9.2
http://redmine.ruby-lang.org/issues/4994

Author: Sylvain Viart
Status: Rejected
Priority: Normal
Assignee: 
Category: lib
Target version: 1.9.2
ruby -v: ruby 1.9.2p180 (2011-02-18 revision 30909) [x86_64-linux]


How to reproduce:
<pre>
require 'delegate'
require 'pp'

def test_that?(str)
    str.size > 0
end

class String2 < DelegateClass(String)
    def initialize(*param)
        @s = String.new(*param)
        super(@s)
    end

    def dummy
        test_that?(@s)
    end
end

s2 = String2.new("pipo")

pp s2.dummy
</pre>

The code above works under 1.9.1 and 1.8 but not under 1.9.2

* ruby1.9.1 -v => ruby 1.9.1p378 (2010-01-10 revision 26273) [x86_64-linux]

* ruby -v      => ruby 1.9.2p180 (2011-02-18 revision 30909) [x86_64-linux]
