java_bin

This is an Apache Solr JavaBin format (binary format) implementation for Ruby.

Features

  • fast parse(2.5 - 5 times faster than ruby eval), and less network traffic.

  • rsolr/solr-ruby support.

  • pure and c extension code.

  • ruby 1.8/1.9 support.

Requirements

  • Ruby1.8.7 or later (include 1.9.x)

  • (recommended) C compiler (gcc or vc++): you can also use java_bin without c extension, but ‘pure’ is 30 times slower than ‘ext’.

  • JavaBin has been tested with MRI 1.8.7, REE 1.8.7, YARV 1.9.2 pre1 on Ubuntu Linux 9.10 (32bit) and MRI 1.8.6 on Windows Vista (32bit), and Apache Solr 1.4

Install

(Linux)
gem sources -a http://gemcutter.org
gem install java_bin

(Windows)
fix (path to)\ruby\lib\ruby\1.8\i386-mswin32\config.h
  #if _MSC_VER != 1200
    ↓
  #if _MSC_VER < 1200

start => visual studio c++ 200x xxxx edition => visual studio tools => visual studio 200x command prompt
gem sources -a http://gemcutter.org
gem install java_bin
  or
cd (path to)\ext\java_bin\ext
ruby extconf.rb
nmake

Simple Usage

require 'rubygems'
require 'java_bin'

@parser = JavaBin.parser.new
result = @parser.parse( javabin format string )

With RSolr/Solr-Ruby

  • By RSolr/Solr-Ruby support, a parser automatically uses javabin format instead of ruby format.

require 'rubygems'
require 'rsolr'
require 'java_bin'

solr = RSolr.connect
solr.select :q => '*:*'

TODO

  • more parse speed

  • license

  • pure parse encoding bug (1.9.x)

  • shared string over parsing

  • windows build(1.9.x)

  • 64bit build

  • builder(writer)作成

  • JRuby support

References

Note on Patches/Pull Requests

  • Fork the project.

  • Make your feature addition or bug fix.

  • Add tests for it. This is important so I don’t break it in a future version unintentionally.

  • Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)

  • Send me a pull request. Bonus points for topic branches.
