NAME

SYNOPSIS
a simple memory leak detector for ruby with preconfigured rails hooks.
INSTALL
gem install dike
URIS

DESCRIPTION
the concept behind dike.rb is simple: class Object is extended in order that the location of each object's creation is tracked. a summarizer command is given to walk ObjectSpace using each object's class and the location if it's creation to detect memory leaks. not all leaks can be detected and some that are may not really be leaks, but dike provided a simple way to see the hotspots in your code that may potentially be leaking.
HISTORY
0.0.4:
- under rare circumstances dike itself interacted strangely with certain classes and caused them to leak, HTTPOK was one such example. this release fixes that bug. thanks to Jan Kubr for providing a great test case that helped me fix this.
EXAMPLES
### PURE RUBY
## just dumping sequential snapshots to stderr, looking at a specific class
# cfp:~ > cat sample/a.rb require 'dike'
class Leak < ::String end
Leaks = Array.new
Dike.filter Leak
loop do Leaks << Leak.new('leak' * 1024) Dike.finger sleep 1 end
# cfp:~ > ruby sample/a.rb | less
