John Hawthorn 04bc4c0662 Resize capacity for fstring ... When a string is #frozen, it's capacity is resized to fit (if it is much larger), since we know it will no longer be mutated. > puts ObjectSpace.dump(String.new("a"*30, capacity: 1000)) {"type":"STRING", "class":"0x7feaf00b7bf0", "bytesize":30, "capacity":1000, "value":"... > puts ObjectSpace.dump(String.new("a"*30, capacity: 1000).freeze) {"type":"STRING", "class":"0x7feaf00b7bf0", "frozen":true, "bytesize":30, "value":"... (ObjectSpace.dump doesn't show capacity if capacity is equal to bytesize) Previously, if we dedup into an fstring, using String#-@, capacity would not be reduced. > puts ObjectSpace.dump(-String.new("a"*30, capacity: 1000)) {"type":"STRING", "class":"0x7feaf00b7bf0", "frozen":true, "fstring":true, "bytesize":30, "capacity":1000, "value":"... This commit makes rb_fstring call rb_str_resize, the same as rb_str_freeze does. Closes: https://github.com/ruby/ruby/pull/2256		2019-06-26 15:01:48 +09:00
