引言

和來自全球 80 個不同公司超過 2000 位的開發人員, OpenStack 是目前最大型的軟體合作開發專案之一. Because of its size, it is characterized by a huge diversity in social norms and technical conventions. These can significantly slow down the speed at which newcomers are successful at integrating their own roadmap into that of the OpenStack project.

我們已經設計了一系列的課程來幫助程式設計師和軟體開發人員來跨越貢獻時所遇到的障礙 It shows them how to ensure their bug fix or feature is accepted in the OpenStack project in a minimum amount of time. The educational program requires students to work on real-life bug fixes or new features during two days of real-life classes and online mentoring, until the work is accepted by OpenStack. The live two-day class teaches them to navigate the intricacies of the project's technical tools and social interactions. In a followup session, the students benefit from individual online sessions to help them resolve any remaining problems they might have.

課程大綱

第一天

Introduction

• 在第一天的開始之前: choice of a contribution, via email, with each participant
• 第一天: OpenStack 是如何產生出來的
• 第一天: 學習和練習 git, gerrit, IRC

• 第二天: 貢獻的理論基礎
• 第二天: Lego contribution simulation
• 第二天: Individual presentation of the contribution plan
• 第二天: 線上指導

OpenStack 是如何產生出來的 ( 3 小時 包括 1 小時 30 分鐘的練習時間 )

• Release cycle ( slides )
  • Planning (Design, Discuss and Target)
  • Implementation (Milestone iterations)
  • Pre-release (Release Candidates dance)
    • Release candidate 1
    • Other release candidates
    • Release day
  • 練習: based on the Juno release schedule find the URL of a document or a patch that belongs to each of the above steps.
• Relevant actors ( slides )
  • commiters companies
  • commiters individuals (bottom of the page)
  • Your management
• Technical Committee ( slides )
  • Decide what is an OpenStack Program
  • meetings
  • 練習: read archived and briefly comment on keystone document
  • PTLs
  • APC
  • ATC
  • 練習: each APC / ATC in the class add a URL to the etherpad proving it
• Program ecosystem ( slides )
  • Incubated
  • Integrated
  • Core
  • Stackforge
  • 練習: What kind of Program do you contribute to ?
• Design summits ( slides )
  • propose sessions
  • attend or lead a session
  • Kilo Summit Etherpads
  • 練習: Add a session proposal regarding your contribution in an etherpad, review two proposals
• IRC meetings ( slides )
  • modified meetbot
  • #info - Add an info item to the minutes. People should liberally use this for important things they say, so that they can be logged in the minutes.
  • #action - Document an action item in the minutes. Include any nicknames in the line, and the item will be assigned to them. (nicknames are case-sensitive)
  • #help - Add a "Call for Help" to the minutes. Use this command when you need to recruit someone to do a task. (Counter-intuitively, this doesn't provide help on the bot)
  • 練習: lunch menu online meeting

  • blueprints
  • bugs
    • Status, Importance, Assigned To, Milestone, Tags
    • reporting a bug
    • confirming and prioritizing
    • debugging
    • bugfixing
  • 練習: review other launchpad bugs and improve yours
• gerrit workflow ( slides )

第二天

The Contribution Process (1 hour)

( slides )

• Take the pulse of the project.
• Figure out who's behind it.
• Determine the project's social groups.
• Assess your approach.
• Engage immediately.
• Play with your network.
• Perform the smaller tasks.
• Choose a question.
• Familiarize yourself with the code of conduct.
• Understand the conventions.
• Explain what you do.
• Prepare the backport.
• Learn what's local and what's upstream.
• Learn what distinguishes good work flow from bad work flow.
• Quantify the delta.
• Speed up the acceptance.

• Maximize karma.
• Work in parallel.
• Archive and collect.

Agile for Contributors ( 15 分鐘 )

( slides )

• Apply agile
• Who is the customer?
• Company & Upstream product owner
• Sprint review presentation to Upstream

Contribution Simulation (2 hour)

The students make a virtual contribution simulation using Lego bricks as props, with the goal of expanding a Lego town, built by upstream. They are divided into teams; the teacher is by turns the product owner in the company and the upstream.

Contribution Planning ( 2 小時 )

( odp slides pdf slides )

• The students use template slides to prepare a 5-minute presentation of their planned contribution.
• A sample presentation is given by the teacher, as an example.
• Each student group prepares a presentation describing:
  • the contribution they plan to work on during the online sessions,
  • how they will engage with the Upstream,
  • how it contributes to the company's agenda
  • and whom they will be working with.
• Each student group presents its slides to the class
