Process Safe Logger

testing ruby: 1.9.3, 2.0.0;

Process Safe Logger supports log rotations in multi-processes safely.

Ruby's standard Logger class originally have had a problem that it's log rotation function does not work safely in multi process environment. This gem fixes the problem.

The patch is already pull requested to the github.com:ruby/ruby and will be released with ruby 2.1.0.

gem install process_safe_logger

require 'process_safe_logger'
logger = ProcessSafeLogger.new('logfile.log', 3, 1024)

Option parameters are same with Ruby's Logger. See docs.ruby-lang.org:Logger.
