BetterRailsDebugger

NOTE ABOUT NEW BACKTRACE FEATURE ON 0.2: Backtrace feature is in a really heavy development and contains bugs you can use it as a general reference. Get a backtrace of an already allocated object it's not simple (or is not for me :P). I hope you understand. With love, Angaroshi <3

DISCLAIMER: This gem is in a really early development stage, you can start to use it, but do not expect a lot of features. Right now, the only supported feature it's track Ruby objects creations.

Add a a couple of code analyzers that helps you to find where you are loosing performance or memory.

Remember that tack memory allocation and free it's really expensive and is going to affect the performance in your env.

DON'T USE THIS GEM IN PRODUCTION UNLESS YOU ACCEPT TO LOOSE PERFORMANCE

Installation

Better Rails Debugger it's a rails engine and you need to mount it into an existing rails app. To do this add this line to your application's Gemfile:

gem 'better_rails_debugger'

And then execute:

$ bundle

Configuration

1. Mount the engine in routes.rb:

mount BetterRailsDebugger::Engine => "/debug"

2. Enable Sidkiq (or any other activejob backend) in config/application.rb (remember you need to install sidekiq first):

config.active_job.queue_adapter = :sidekiq

3. Start sidekiq

bundle exec sidekiq

3. Set MongoID database.yml file:

In rails 5 run:

rails g mongoid:config

change the file configuration and/or rename it.

Create an initializer to configure like config/initializers/better_ruby_debugger.rb

BetterRailsDebugger.configure do |c|
  c.mongoid_config_file = 'config/mongoid_memory.yml'
end

Usage

Once everything installed and configured, you can go to http://localhost:3000/debug

Once you have the id of the group, you can start analysing code, for example, we are going to analyze all our rails controller actions:

class ApplicationController < ActionController::Base
  protect_from_forgery with: :exception

  around_action :do_analysis

  def do_analysis
    BetterRailsDebugger::Analyzer.instance.analyze "#{request.url}", "5a98a93f50f04b079458fd57" do
      yield
    end
  end
end

With this, we can just go to our app, run the code and start to see some results:
