と言いつつ、英語できないのでかな混じりパッチ(for 1.6)です。
せめてと思い ((<>)) をとっぱらっておきました。あと、可能な限
り例もつけてます。
以下について注意。(パッチ中では ?????と印つけてます)
: lib/resolv.rb, lib/resolv-replace.rb
これを使えば、名前解決中のタイムアウトの処理が可能になるかどうかを
試してません。該当部分の記述は削って良いかな。
: $SAFE / def
$SAFE == 4 のときのメソッド定義は現状でも許されてないみたいです。
(エラーメッセージは変わってるけど、どういう変更だったのか
をまだ追ってません)
例
$SAFE = 4; def a; end
=> -:1: Insecure operation `(null)' at level 4 (SecurityError)
ruby 1.6.4 (2001-06-04) [i586-linux]
=> -:1: Insecure: can't define method (SecurityError)
ruby 1.6.4 (2001-08-06) [i586-linux]
詳細は
<http://www.ruby-lang.org/ja/man-1.6/?cmd=view;name=ruby+1.6+feature>
を参照願います。
: Ctrl-C (Interrupt)が効かなくなる
というのを ruby 1.6 feature には書いていたのですが
# [ruby-dev:13195] で報告 [ruby-dev:13204] でパッチが出てますが。
これって 1.6 にはバックポートしないのかな？それならそれで
いいのですが。
