memcachedで日本語キーを扱う

memcachedの代わりにkyoto tycoonを試してみようとしています。

kyoto tycoonはmemcachedと同じインターフェースで起動できるとのことで、当然memcachedライブラリが使えます

日本語のキーが使えるかどうか確認します

memcachedライブラリ

$ su
# export http_proxy=proxy:port
# gem install memcached

$ su

# export http_proxy=proxy:port

# gem install memcached

#!/bin/env ruby -Ku 
# -*- encoding:utf-8 -*-
require "rubygems"
require "memcached"
require "nkf"

cache=Memcached.new "localhost:11211"
cache.set("sony","6758",0)
puts cache.get("sony")
key="ソニー"
cache.set(key,"ｿﾆｰ",0)
puts cache.get(key)

#!/bin/env ruby -Ku

# -*- encoding:utf-8 -*-

require "rubygems"

require "memcached"

require "nkf"

cache=Memcached.new "localhost:11211"

cache.set("sony","6758",0)

puts cache.get("sony")

key="ソニー"

cache.set(key,"ｿﾆｰ",0)

puts cache.get(key)

$ ruby mem.rb 
6758
/Library/Ruby/Gems/1.8/gems/memcached-1.5.0/lib/memcached/memcached.rb:630:in `reraise': Key {"ソニー"=>nil} (Memcached::ABadKeyWasProvidedOrCharactersOutOfRange)

$ ruby mem.rb

なんかだめ。。

ちなみにperlだと

#!/usr/bin/perl

use strict;
use warnings;
use Cache::Memcached::Fast;

my $memd=Cache::Memcached::Fast->new({
		servers => [ { address => 'localhost:11211' }], 
}); 

# 値を追加 key => value
my $key='ソニーal';
$memd->set($key=> 'そにー2');

# 値を取得
my $id = $memd->get($key);
print "$id\n";

#!/usr/bin/perl

use strict;

use warnings;

use Cache::Memcached::Fast;

my $memd=Cache::Memcached::Fast->new({

servers => [ { address => 'localhost:11211' }],

});

# 値を追加 key => value

my $key='ソニーal';

$memd->set($key=> 'そにー2');

# 値を取得

my $id = $memd->get($key);

print "$id\n";

$ perl mem.pl
そにー2

1 2	$ perl mem.pl そにー2

rubyのライブラリが悪いようだ

ちなみにOSはMountain Lion
