Zookeeper logger throws exception on Windows/JRuby

[CootCraig]

I don't know if there is a way to set the logger, but with JRuby on windows I get an exception the following Logger.new:

lib\ruby\gems\1.8\gems\slyphon-zookeeper-0.9.2-java\lib\zookeeper.rb
class Zookeeper < ZookeeperBase
unless defined?(@@logger)
@@logger = Logger.new('/dev/null').tap { |l| l.level = Logger::FATAL } # UNIX: FOR GREAT JUSTICE !!
end

$ jruby -v
jruby 1.6.7 (ruby-1.9.2-p312) (2012-02-22 3e82bc8) (Java HotSpot(TM) Client VM 1.6.0_31) [Windows Server 2008 R2-x86-java]

Exception outpout:

D'oh, i knew this day would come. I do zero windows testing, so YMMV. I'll fix this to use stderr instead and push a new build.

[slyphon]

BTW, if you are using zookeeper for application development, you might want to look at ZK which is a higher-level wrapper around this library, and provides a much nicer API for registering for events, cluster-wide locks, and so forth.

[CootCraig]

I will be looking at ZK for coding. This was instigated by my first attempt at DCell, had no idea what dependencies would be pulled in :-) Thanks for the quick response.

[slyphon]

Hey, I've pushed a release of zookeeper-0.9.3 which ZK won't see. I'll push a slyphon-zookeeper-0.9.3 so ZK will pick up on it, and in the 1.2.0 release of ZK we'll use the zookeeper gem.

It's a little confusing, as twitter just gave me this repo, but we should have it all worked out soon :)

[slyphon]

ok, pushed

Have a look and let me know if that fixes it for you :)

[CootCraig]

Sorry I haven't tried this out yet, busy at home and work. I'm using Jruby,Sinatra,Celluloid and thought I'd be using the DCell extension of Celluloid. Anyway the current task is handled by Ruby/0mq binding support in Celluloid. When the current work project is in delivered I'll try this out. I have plans for using Zookeeper with DCell in the future.

Cool, sounds good :)
