New in Edge Rails

I was watching the rails commits and noticed this. They have just added something called orchestra to ActiveSupport. It is an instrumentation tool for ruby and rails. Below is the documentation from orchestra.rb.

Orchestra provides an instrumentation API for Ruby. To instrument an action

# in Ruby you just need to:

#

# ActiveSupport::Orchestra.instrument(:render, :extra => :information) do

# render :text => "Foo"

# end

#

# Those actions are consumed by listeners. A listener is anything that responds

# to push. You can even register an array:

#

# @listener = []

# ActiveSupport::Orchestra.register @listener

#

# ActiveSupport::Orchestra.instrument(:render, :extra => :information) do

# render :text => "Foo"

# end

#

# event #=> ActiveSupport::Orchestra::Event

# event.name #=> :render

# event.duration #=> 10 (in miliseconds)

# event.result #=> "Foo"

# event.payload #=> { :extra => :information }

#

# Orchestra ships with a default listener implementation which puts events in

# a stream and consume them in a Thread. This implementation is thread safe

# and is available at ActiveSupport::Orchestra::Listener.

#

Ruby Enterprise Edition version 1.8.7 has just been released you can download it here.
