Ironruby core - Oct 2008 - Annoymous class extending a module doesn't return expected kind_of

Hi guys,

I''ve been bashing my head again this problem for the last few days
where the object I expected wasn''t passed around, tonight I decided to
break it down and focus on a much small part.  Turns out, I was
looking in the wrong part.

This is what I think the problem is. The code is creating an anonymous
class which is extending a module.  The code then does a kind_of? to
decide what to do with it.
>From what I can tell, it looks like the kind_of doesn''t recognize
the
modules it is extending.  This is the code which demonstrates the
problem:

Code Repro:
module AAA
   class << self
     def a
      puts "Hello"
     end
   end

  def myAAA
    klass = Class.new do
        extend AAA
    end

    puts "Am I a type of what I extended (AAA)?"
    puts klass.kind_of?(AAA)
  end
end

class XYZ
  include AAA
end

$a = XYZ.new
$a.myAAA


With MRI, true is returned.  With IronRuby, false is returned.

Output:

E:\IronRuby\trunk\build\debug>ruby array_test
Am I a type of what I extended (AAA)?
true

E:\IronRuby\trunk\build\debug>ir array_test
Am I a type of what I extended (AAA)?
false


This has blocked me moving on.  Anyone got any ideas?

Any help on this would be great!

Thanks

This is working for me with our internal sources but not with what''s
current in RubyForge.  I think we might be a few days behind on the sync -- you
should see it working after the next one happens.

Hi Curt,

Any ideas when the next release will happen? Is this going to be a
post PDC thing?

Hi Stefan,

Looks like you are working on the same item as me :)

This is the last problem I have I think to run unmodified RSpec, well
until I hit the next thing :)

Oh, no -- we''re doing it pretty regularly.  I think there''s
just been a short delay while we pull in Peter''s work and that
we''ll probably push back out in the next two days.  We''re
totally not optimized for outside contributions at this point, but "working
from a single repository" is on someone''s list of commitments for
the next year.

Excellent. I''ll continue with my work around until then :)

I''ll go over the changes i''ve made locally and raise bugs
where
required tonight.  Sadly, they are all core so I can''t submit them
myself.

Cheers
