Profiling memory leaky Sidekiq applications with Ruby 2.1

My largest Sidekiq application had a memory leak and I was able to find and fix it in just few hours spent on analyzing Ruby's heap. In this post I'll show my profiling setup.

As you might know Ruby 2.1 introduced a few great changes to ObjectSpace, so now it's much easier to find a line of code that is allocating too many objects. Here is great post explaining how it's working.

I was too lazy to set up some seeding and run it locally, so I checked that test suite passes when profiling is enabled and pushed debugging to production. Production environment also suited me better since my jobs data can't be fully random generated.

So, in order to profile your worker, add this to your Sidekiq configuration:

Disable CSS Animations in Poltergeist & Phantomjs. Phantomjs does not like to wait for animations, and you can run in to nasty test flickers because of it. This pattern will disable animations in test env, and not touch any app code. 
# env.rb or spec_helper.rb

Capybara.register_driver :poltergeist do |app|
  opts = {
    extensions: ["#{Rails.root}/features/support/phantomjs/disable_animations.js"] # or wherever
  }

  Capybara::Poltergeist::Driver.new(app, opts)
end

Build your own private, encrypted, open-source Dropbox-esque sync folder

Prerequisites:

  • One or more clients running a UNIX-like OS. Examples are given for Ubuntu 12.04 LTS, although all software components are available for other platforms as well (e.g. OS X). YMMV
  • A cheap Ubuntu 12.04 VPS with storage. I recommend Backupsy, they offer 250GB storage for $5/month. Ask Google for coupon codes.

Software components used:

  • Unison for file synchronization
  • EncFS for folder encryption

Python script to create server SSL certs and sign them with a custom CA.
#! /usr/bin/python
"""
This simple script makes it easy to create server certificates
that are signed by your own Certificate Authority.
Mostly, this script just automates the workflow explained
in http://www.tc.umn.edu/~brams006/selfsign.html.
Before using this script, you'll need to create a private
