Very technical response - thanks for the rebuttal, I'm sure the "related developer" will be more than happy to implement a patch which turns off a callback that clearly and without question is valid in a multitude of cases. Your reasoned argument clearly shows the error of my ways....... Thanks again! ---------------------------------------- Bug #5015: method_added" is called in addition to "method_undefined http://redmine.ruby-lang.org/issues/5015 Author: Lazaridis Ilias Status: Open Priority: Normal Assignee: Category: Target version: ruby -v: 1.9.2 When a method is undefined via "undef_method :any_method", the following methods are called back: * method_added * method_undefined The expected behaviour is that only "method_undefined" is called (similar to "remove_method"). - class String def self.method_added(id) puts "callback: added #{id.id2name}" end def self.method_undefined(id) puts "callback: undefined #{id.id2name}" end def self.method_removed(id) puts "callback: removed #{id.id2name}" end end puts "\nundef method (buildin)" class String undef_method :capitalize end puts "\ndefine method" class String def any_method(*args) nil end end puts "\nundef method" class String undef_method :any_method end puts "\ndefine method" class String def any_method(*args) nil end end puts "\nremove method" class String remove_method :any_method end - OUTPUT: undef method (buildin) callback: added capitalize callback: undefined capitalize define method callback: added any_method undef method callback: added any_method callback: undefined any_method define method callback: added any_method remove method callback: removed any_method -- http://redmine.ruby-lang.org
