It's really this easy? If so, I'll send over my public key today :)

[ruby-core:50864] [ruby-trunk - Bug #7554][Open] TracePoint#defined_class doesn't return Class or Module

From: "ko1 (Koichi Sasada)" <redmine@...>
Date: 2012-12-13 08:29:57 UTC
List: ruby-core #50864
Issue #7554 has been reported by ko1 (Koichi Sasada).

----------------------------------------
Bug #7554: TracePoint#defined_class doesn't return Class or Module
https://bugs.ruby-lang.org/issues/7554

Author: ko1 (Koichi Sasada)
Status: Open
Priority: Normal
Assignee: ko1 (Koichi Sasada)
Category: core
Target version: 2.0.0
ruby -v: ruby 2.0.0dev (2012-12-01 trunk 38127) [i386-mswin32_100]


In some case (using singleton method),
TracePoint#defined_class doesn't return Class or Module.

# example
def self.foo
end

obj = Object.new

def obj.foo
end

module M
  def baz
  end
end

class C
  include M
  def self.bar
  end
end

TracePoint.trace(:call){|tp|
  p [tp.defined_class, tp.defined_class.kind_of?(Module)]
}

foo
obj.foo
C.bar
C.new.baz

#=>
# ruby 2.0.0dev (2012-12-01 trunk 38127) [i386-mswin32_100]
[main, false]
[#<Object:0x2d8267c>, false]
[C, true]
[M, true]

###

The name `defined_class' expected to return object of Class or Module.
So it should be return Class or Module.

The following patch fixes this issue.

-		trace_arg->klass = rb_iv_get(trace_arg->klass, "__attached__");
-	    }
 	}
 	else {
 	    trace_arg->klass = Qnil;

After that, that script shows:

###
[#<Class:#<Object:0x874b244>>, true]
[#<Class:#<Object:0x873f9a8>>, true]
[#<Class:C>, true]
[M, true]
###

Current behavior is from `set_trace_func' (6th parameter of block).

But TracePoint is newer, no compatible issue.
