An enhanced MySQL database driver. With support for async operations and threaded database access.


gem build mysqlplus.gemspec

on OSX with the default mysql installed:

  sudo gem install mysqlplus-0.1.0.gem -- --with-mysql-config

on OSX, with mysql installed by macports:

  sudo gem install mysqlplus-0.1.0.gem -- --with-mysql-config=/opt/local/lib/mysql5/bin/mysql_config

on OSX, with x86 mysql (NOT x86_64!) installed from

  sudo env ARCHFLAGS="-arch i386" gem install mysqlplus-0.1.0.gem -- \
    --with-mysql-dir=/usr/local/mysql \
    --with-mysql-lib=/usr/local/mysql/lib \


to use within rails
add require 'mysqlplus' to the top of environment.rb
this instantiates the Mysql class that you can use.
and it will automagically use async_query instead of query, so it's a drop in replacement.

Same with other scripts that want to use it--just require 'mysqlplus' BEFORE you require 'mysql' and it will 
load the asynchronous version, then ignore the sequent require 'mysql' call.

Other helpful mysql utilities:

slim attributes boosts mysql speed by using arrays instead of hashed lookup.
Hash extension gem also results in speedups when used:


Aman Gupta, for help in threading support and improved tests Tomita Masahiro–since this is a fork of his already excellent mysql lib []. Roger Pack, for helping in the file descriptor hunt :) Lourens Naude for 1.9 integration help.
