Bug #11130

Updated by nobu (Nobuyoshi Nakada) almost 9 years ago

 須藤です。 

 ~~~diff

 +      if (NIL_P(size) || size == Qundef) { 
 + 	 ary = rb_ary_new(); 
 +      } 
 +      else { 
 + 	 ary = rb_ary_new_capa(NUM2LONG(size)); 
 +      } 

 ~~~ 
  
  を 

 ~~~c 
     
 
 ~~~ 
      if (FIXNUM_P(size)) { 
	 
 	 ary = rb_ary_new_capa(NUM2LONG(size)); 
     
      } 
     
      else { 
	 
 	 ary = rb_ary_new(); 
     
      } 

 ~~~ 
  
  とかsizeが返す値が数値じゃなかったらこれまでと同じ挙動にする 
 
  ようにしてもらえないでしょうか？ 

 
 
  これまでは 

 ~~~ruby 
 
 
 ~~~ 
  class NonIntegerSizeEnum 
   
    include Enumerable 

   
 
    def initialize(n) 
     
      @n = n 
   
    end 

   
 
    def each 
     
      @n.times { |i| yield i } 
   
    end 

   
 
    def size 
     
      :size 
   
    end 
 
  end 

 

  NonIntegerSizeEnum.new(100).to_a 
 ~~~ 

  
 
  というコードが動いていたんですが、この変更の後からは 

 
 
 > /tmp/b.rb:17:in `to_a': no implicit conversion of Symbol into Integer (TypeError) 

 

  というエラーがでるようになってしまって困っています。
