Week 3

Week 4

  • More Git
    • Understanding how git works
      • SHAs
      • commits, trees, blobs
      • branches
      • Working Directory vs. Staging Area vs. HEAD
    • Git Walkthrough Part I
    • Git Walkthrough Part II
    • Some basic git commands you should make sure you know how to use:
      • git clone - clone an existing repository (i.e., one you've forked on GitHub)
      • git status - check what's happening with your repo, working directory, branch info
      • git add - add a file, files, or folder(s) of file(s)
      • git commit - commit changes in the staging area
      • git log - look back at existing commits
      • git diff - look at the difference between what's in the working directory and staging area, or between two commits
      • git rm - remove a file
      • git mv - move or rename a file
      • git reset - update the staging area, and perhaps working directory, with files from another commit (e.g., HEAD)
      • git checkout - switch to a branch or commit, or create, or get files from a branch/commit

Week 5

  • 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
