Author: Watson <watson1978@gmail.com> Date: 2011-04-09 (Sat, 09 Apr 2011) Changed paths: M lib/stringio.rb Log Message: ----------- StringIO#{each, readlines} will raise an ArgumentError when was passed 0 to limit because limit 0 causes infinity loop. Test Script: {{{ require 'test/unit/assertions.rb' include Test::Unit::Assertions require 'stringio' f = StringIO.new("foo\nbar\nbaz\n") assert_raise(ArgumentError){ f.readlines(0) } assert_raise(ArgumentError){ f.readlines("", 0) } assert_raise(ArgumentError){ f.each_line(0){ } } assert_raise(ArgumentError){ f.each_line("", 0){ } } assert_nothing_raised{ f.each_line(0) } obj = Object.new def obj.to_int; 0; end assert_raise(ArgumentError){ f.readlines(obj) } puts :ok }}}
