DPS909 and OSD600 Fall 2013 Notes

Introduction

The fall is broken into two parts. First, general open source and and community (i.e., Mozilla) specific skills and ideas are taught. Students learn how to deal with the tools, techniques, and practices of their chosen project and its community. Second, we go deep into open web development with a case study.

Learning Git

• Case Study - Debugging Webmaker.org Events Crash
  • We've been trying to fix a really bad crash for the past week - https://bugzilla.mozilla.org/show_bug.cgi?id=914904
  • Open Source relies on History
    • Issues, Bugs (why we did what we did, who reviewed it)
    • Source Code Revision History (what we did, who did it, when it was done)
  • Often fixing things requires knowing the past more than digging into the code itself
    • mozilla/webmaker-events repo
    • mozilla/webmaker.org repo
  • Archaeology
    • Compare View (what changed between two shipped versions of the app?) https://github.com/mozilla/webmaker.org/compare/v0.0.140...v0.0.142 (notice the syntax /compare/[revA]...[revB]
    • When, where did we move webmaker-events into webmaker.org? https://bugzilla.mozilla.org/show_bug.cgi?id=912241
    • The code that landed (i.e., got checked in) on Sept 4th: https://github.com/mozilla/webmaker.org/commit/c9951521b5fb9113b3e46cbbb87125bc60b22f81
    • Something looks wrong in this code: using Blame to figure out who did what, when: https://github.com/mozilla/webmaker-events/blame/master/controllers/events.js
    • We're missing some code! https://github.com/mozilla/webmaker-events/commit/4c971c81f619c0fc63946f4380ca9a384d9633cc
    • Let's fix things, we need a new bug: https://bugzilla.mozilla.org/show_bug.cgi?id=916839
