Week 4

Week 5

  • Forking vs. Merging
    • Anyone can fork, not everyone can get work merged back in
    • My Repo: my house my rules
    • Some famous Forks
      • Firefox from Mozilla Suite
      • WebKit from KDE's KHTML
      • Blink from WebKit
      • Ubuntu from Debian
      • Sun's StarOffice became OpenOffice became LibreOffice
      • WordPress from Cafelog
      • MariaDB from MySQL
      • FireOS (Amazon for Kindle) from Android
      • io.js from node.js, which eventually became the official node.js
    • Example Fork
      • Semantic UI
      • Fomantic UI - "Fomantic was created to continue active development of Semantic-UI and has the intent to be merged back into the master repository once active development can restart."
  • Merging with git
    • Where git branch splits histories apart, git merge brings them back together
    • Understanding DIFFs and Patch files
    • Types of Merges: Fast Forward, Recursive Merges are the most common
      • --ff-only to force a fast-forward (only the branch pointer is moved, no new commit is created)
      • 3-way merges: two branch commits with a common ancestor (new commit is created with multiple parents)
      • Can have any number of parents though: one of the larges is a 66 commit octopus merge in the Linux kernel
    • How to merge
      • start with a clean working directory
        • commit your work if you can; or
        • stash (git stash list, git stash show, git stash pop)
      • checkout the branch you want to merge into
      • git merge branch_to_merge_into_this_branch
    • Various flags and commands to know:
      • git merge --squash
      • git merge --abort
      • git merge --continue
      • git branch -d
    • Merge Conflicts
      • Conflict markers <<<<<<<<<, =============, >>>>>>>>>>>>
    • Doing big merges in git
  • TODO
    • Release 0.2
    • Lab 4 - Complete your first Hacktoberfest PR, and write your first blog post about your fix. See guidelines in the Release 0.2 page. Place both links in a new section under the Submission section.
