|Summary: Date.parse raises NoMethodError
|
|Initial Comment:
|In the version 1.8.4 
|
|Date.parse('-1') 
|
|used to raise 'ArgumentError: invalid date' error. Now it raises NoMethodError:
|
|irb(main):002:0> Date.parse '-1'
|NoMethodError: undefined method `[]' for nil:NilClass
|        from /usr/local/lib/ruby/1.8/date.rb:800:in `complete_hash'
|        from /usr/local/lib/ruby/1.8/date.rb:875:in `new_with_hash'
|        from /usr/local/lib/ruby/1.8/date.rb:922:in `parse'
|        from (irb):2
|        from /usr/local/lib/ruby/1.8/rational.rb:174
|
|The patch below fixes it:
