ぼくの障害/バグ対応レシピ #gotandapm
1.
はじめてのPerl6 障害/バグ対応レシピ @okazu_dm
2.
自己紹介 • @okazu_dm(岡田 数馬) •
渋谷でWebエンジニアをやってます • 実はPerl歴 < バイトのPython/PHP歴
3.
タイトルについて • YAPCあたりからPerl6でポチポチ遊んでみた • そういえばVMが選べるしそのあたりの話しよ うかなと思っていた •
Moar, JVM, Parrot • あれ?そういえばこんな話聞いたことがあるような.... (昨日の時点)
4.
5.
というわけで
6.
障害やバグを見つけた時の 調査によく使ってるツールの 紹介をします
7.
最初に
8.
つけよう gオプション perlbrewなら perlbrew install perl-5.8.8
-DEBUGGING=-g
9.
gdb & gdbperl.pl •
gdbperl.pl: gdbによるperlのデバッグを非常 に便利にしてくれるツール • 以前、特定のプロセスがシグナルハンドラの 実装によってハングアップした時に出番があっ た
10.
たのしいSEGV • SEGFAULTした時のデモします
11.
strace, ltrace, ftrace •
strace: システムコール単位での記録が可能。 この前ビルドしたPerlがテストでコケる時に使いました。 • ltrace:共有ライブラリ(.so)の関数呼び出しが見れる。あま り使ったことはないです • ftrace:カーネル内の関数呼び出しをトレースできる。カー ネルのビルドの際にパラメータを付けている必要がある が、デバイスドライバなどのデバッグに非常に役立つ (仕事では使ったことないです)
12.
straceの様々なオプション • p :
プロセスにattach • f : スレッドも追います • o: ファイルに出力 • e: 表示するシステムコールをフィルタリングでき ます。 • その他いくつか
13.
その他 • tcpdump &
wireshark:ネットワーク周り • フィルタの書き方を忘れなければ便利
