Bug #9381

Updated by nobu (Nobuyoshi Nakada) over 6 years ago

=begin 
 Ruby 2.1.0 won't fetch objects when the lookup key overrides (({#hash})) #hash and (({#eql?})). 
 #eql?. This is a regression as it works as expected in ruby 1.8, 1.9 and 2.0. 

  

 ------------- 
 class Wrapper 
    
   def initialize(obj) 
      
     @obj = obj 
    
   end 

    

   def method_missing(symbol, *args, &block) 
      
     @obj.__send__(symbol, *args, &block) 
    
   end 

    

   def hash 
      
     @obj.hash 
    
   end 

    

   def eql?(other) 
      
     @obj.eql?(other) 
    
   end 
  
 end 

  

 hash = { 5 => "LOOKUP SUCCEEDED" } 

  

 # Prints "LOOKUP SUCCEEDED" on RUBY < 2.1.0. Fails on RUBY 2.1.0. 
  
 p hash[Wrapper.new(5)] 
 =end
