[#35071] Bug in system()? — Anthony Wright <anthony@...>
I've just hit a problem where the system() method to call an external program failed in a fairly unpredictable way, and I couldn't get any clues from within ruby to diagnose the problem. As a result I ended up debugging process.c to work out what the problem was.

Issue #4440 has been reported by Yusuke Endoh.
----------------------------------------
Bug #4440: odd evaluation order in a multiple assignment
http://redmine.ruby-lang.org/issues/4440
Author: Yusuke Endoh
Status: Open
Priority: Normal
Assignee: Yukihiro Matsumoto
Category:
Target version: 2.0
ruby -v: ruby 1.9.2p0 (2010-08-18 revision 29036) [i686-linux]
遠藤です。
Ruby は左から右に評価が進むと信じていたのですが、多重代入で裏切られました。
def foo
p :foo
[]
end
def bar
p :bar
end
x, foo[0] = bar, 0
bar より foo が左にあるので、:foo 、:bar の順に出力されることを期待するのですが、なんと :bar 、:foo になります。
具体的に何が困るかというと、例えば
obj, obj.foo = obj.foo, obj
には swap を期待するわけですが、そうなりません。こういうコードは実際に、木の回転などを実装するときにしばしば書きたくなります。この挙動に気がついたのも splay tree を実装していたときでした。こんなの:
t.left, t.left.right, t = t.left.right, t, t.left
1.9 系列で修正すべきとまでは思いませんが、2.0 で直る可能性はあるでしょうか。
IRC で話したら「それで普通」みたいな反応もありましたが、
foo[0] = bar
はちゃんと :foo 、:bar の順に出ます。
