Architecture of GitLab as an Open Source Project

In this talk I'll briefly explain how GitLab was composed from different components, and what do each different components do, and how I contribute to GitLab. If you would also like to contribute to GitLab, then you'll certainly need to know where you need to get started for the contribution you want to make. This talk would be a nice introduction for you. If you are just interested in large software architecture in general, then this should also be interesting for you.

Outline

• Who am I
• Introduction to GitLab
  • What is GitLab

# Like OpenStruct but doesn't let you read a non-assigned value (raises instead of returning nil).
# This avoids issues where you read the wrong value due to a typo and don't notice.

class HalfOpenStruct
  def initialize(hash = {})
    @hash = hash
  end

  def include?(name)
    @hash.include?(name)

Rails 4 Silenceable Logger

For when you really, really don't want to log a request.

I'm using this logger to skip logging requests for CarrierWave-uploaded images in development. Loading database dumps from other environments means that the images simply aren't there in development. Rather than deal with an ActiveSupport::RoutingError and a huge 20 line backtrace per missing image, I'm just suppressing all output using this logger and a catchall route that's only active in development.

Usage

Add lib/silenceable_logger.rb to your Rails app, and adapt config/development.rb and config/routes.rb as needed.

When should you use DateTime and when should you use Time?

It's a common misconception that [William Shakespeare][1] and [Miguel de Cervantes][2] died on the same day in history - so much so that UNESCO named April 23 as [World Book Day because of this fact][3]. However because England hadn't yet adopted [Gregorian Calendar Reform][4] (and wouldn't until [1752][5]) their deaths are actually 10 days apart. Since Ruby's Time class implements a [proleptic Gregorian calendar][6] and has no concept of calendar reform then there's no way to express this. This is where DateTime steps in:

>> shakespeare = DateTime.iso8601('1616-04-23', Date::ENGLAND)
=> Tue, 23 Apr 1616 00:00:00 +0000
>> cervantes = DateTime.iso8601('1616-04-23', Date::ITALY)
=> Sat, 23 Apr 1616 00:00:00 +0000
