[ruby-core:65488] [ruby-trunk - Bug #9622] Extra method arguments are magically swallowed after first successful call, possible method cache bug
From:
ruby-core@...
Date:

ruby-core #65488
Issue #9622 has been updated by Marc-Andre Lafortune.
Duplicated by Bug #10291: Strange behaviour of splat in Ruby 2.0.0 added
----------------------------------------
Bug #9622: Extra method arguments are magically swallowed after first successful call, possible method cache bug
https://bugs.ruby-lang.org/issues/9622#change-49266
* Author: Jean Boussier
* Status: Closed
* Priority: Normal
* Assignee:
* Category: core
* Target version:
* ruby -v: 2.0.0
* Backport: 1.9.3: REQUIRED, 2.0.0: DONE, 2.1: DONE
----------------------------------------
The following code behaviour totally change since ruby 2.0.0
~~~
class Foo
def bar(*args)
attribute(:bar, *args)
end
def attribute(name)
puts name
end
end
foo = Foo.new
begin
foo.bar(100)
rescue => e
puts e.class.name
end
foo.bar # legit
5.times do
foo.bar(100)
end
puts 'No errors??? WTF???'
~~~
ruby < 2.0 output:
~~~
ArgumentError
bar
(eval):3:in `attribute': wrong number of arguments (2 for 1) (ArgumentError)
from (eval):3:in `bar'
from foo.rb:28
from foo.rb:27:in `times'
from foo.rb:27
~~~
Which is expected.
But ruby >= 2.0 output
~~~
ArgumentError
bar
bar
bar
bar
bar
bar
No errors??? WTF???
~~~
In short, after the first successful call, the extra arguments are just ignored. I have no idea of what is going on here, but it look like a broken optimization.
All rubies >= 2.0 are affected. 1.8.7 and 1.9.3 are fine.
Regards.
