It’s bleak to have leaks.

third update

Please see here for up-to-date documentation.

second update

There is now a pure-C heap instrumentation as well as the Ruby/ObjectSpace one. You really should be using the C version. It requires you to compile a custom binary, though. Just go to the plugin’s folder (vendor/plugins/bleak_house in your app, or bleak_house-5.1/ in your system’s gems/) and run:

sudo rake ruby:build


I had to junk Rublique because it was introducing its own leaks (via method unbinding) and used an unreliable delta algorithm. Instead the plugin now uses BleakHouse::MemLogger, which is faster and more accurate. Rublique gave me the original idea, so I can’t complain.

A gem version is now available, too. Install and then require 'bleak_house' in config/environment.rb. Usage is the same, but you have to manually install the Rake task in each app (the gem install message will explain).


You can report any issues on the forum. Also, Chris Carter says BleakHouse is starting a trend in emo Ruby-naming.

That’s all. Go scale something already.
