まさおのChangeLogメモ / 2003-03-28

http://objectclub.esm.co.jp/eXtremeProgramming/PetitXPReport/
具体的な実践について良く書けていて興味深い。

簡単に動いたので、結構使えるかと思ったけど、rankdir, fontname あた
りの属性をいじれないのがちょっと痛い。あと、format 指定したファイ
ルを取得するのもあまりうまく制御できないのが、問題かも。

自分で、必要な部分のみ書くかな…。

ruby CVS版にしたら、大丈夫になった。

どうすっぺかな〜。
再現できる簡単なコードが書けると良いんだけど、ちょっと無理そう…。

とりあえず、ruby-1.6.8 にしたらエラーの出る地点がちょっと変わった…。

さらに core ファイルの backtrace を見たところ、以下のように GC 回
りで落ちているよう…。

とりあえず、client3.rb では、GC.disable しておくと大丈夫に。
