■ [Mongrel]MongrelでRailsアプリを動かしてみる。

HSJ.jpでもとりあげたMongrelですが、Win32環境でも動く（しかもWindowsサービスとして）そうなので、ちょっと入れてみることにしました。

インストール

まずはRubyGemsからゲットしてみることにします。アーカイブは一応RubyForgeにもあります。

あれっ(笑)

そうなんですね、今入れてるActiveScriptRubyは1.8.2.6なんですよねぇ…。

ま、仕方ないか。とりあえずruby版を...

C:\Rails>gem install mongrel

C:\Rails>

orz

ってことで、ActiveScriptRuby 1.8.4.1をまず入れます。（先に1.8.2をアンインストールします）

その後、もう一度gemコマンドを実行します。

C:\Rails>gem install mongrel
 ...中略...

C:\Rails>

ということでアッサリ通過。

使い方

Mongrelのサイトに書いてあるとおりこんな感じに実行する。

Windowsサービスについては後述。

開始

C:\Rails>cd app_name
C:\Rails\app_name>mongrel_rails start -d

さっくり動きます。

終了

C:\Rails\app_name>mongrel_rails stop

と思ったけど、Win32環境だとだめっぽ。

CTRL-Pause/Breakで終わらせましょう。

startオプションを確認する

C:\Rails>mongrel_rails start -h

%uの解釈について

やっぱりWEBrick同様にダメっぽい。

該当部分を見てみると、やっぱり考慮されていないですね。

module Mongrel
   class HttpRequest
      def self.escape(s)
         s.to_s.gsub(/([^ a-zA-Z0-9_.-]+)/n) {
            '%'+$1.unpack('H2'*$1.size).join('%').upcase
         }.tr(' ', '+') 
      end

      def self.unescape(s)
         s.tr('+', ' ').gsub(/((?:%[0-9a-fA-F]{2})+)/n){
            [$1.delete('%')].pack('H*')
         } 
      end
   end
end

どうやって修正したものやら。
