Deadlock Retry

Deadlock retry allows the database adapter (currently only tested with the MySQLAdapter) to retry transactions that fall into deadlock. It will retry such transactions three times before finally failing.

This capability is automatically added to ActiveRecord. No code changes or otherwise are required.

Installation

Add it to your Rails application by installing the gem:

sudo gem install negval-deadlock_retry

and including a reference to it in your application’s config/environment.rb:

config.gem 'negval-deadlock_retry', :lib => 'deadlock_retry', :source => 'http://rubygems.com'
