Advanced Git Workshop

The current slides for this workshop can be found in Google Drive.

Old Version of Slides

The slides can be found in slides.md. To build them I have used Marp Next, please check their documentation to get you set up. I personally have simply installed their VS Code extension, and that gets you going, but the CLI works just as well.

Slides Theme

The theme the project uses is haskell by @matsubara0507.

Compiling the Slides

To compile the slides into a nice PDF simply run:

npx @marp-team/marp-cli slide-deck.md --pdf --theme theme.css

Exercises

Below you will find the different exercises which will be run through during the workshop.

Helpful Tools

Showing a Nice Diff Between Branches

git log --graph --pretty=format:'%Cred%h%Creset -%C(yellow)%d%Creset %s %Cgreen(%cr)%Creset' --abbrev-commit --date=relative master..feature-branch

Reset Branch to Remote

git reset --hard origin/feature-branch

Git Rebase Exercise

https://github.com/8thlight/agw-rebase

Run Through

  1. Simple rebase + interactive rebase for squashing
  2. Interactive rebasing for doing both at the same time
  3. Let's go back – there's one change which hasn't caused a conflict, but is wrong. Fix it.
  4. Add a comment somewhere in the code, in the rebased commit, not a new one.
  5. Rewrite commit message after having finished rebasing
  6. Now let's reset the branch and redo this with git merge

Some Questions

  • Why did rebase not mark that one change as conflict? What's the lesson learnt here?
  • How could this whole situation have been avoided in the first place?
  • Once you've finished rebasing, would you force push the branch or create a new one? Why?
  • What's the main difference you've observed between merge and rebase? Which one makes you feel safer? Why? When would you use one or the other?

Git Merge Exercise

https://github.com/8thlight/agw-merge

Some Questions

  • When merging master into feature-branch, which README does it keep? Why? Is it the same when we apply rebase?
  • Run the log after having used merge and after having used rebase. What differences can you see? Hint: use git log --one-line --decorate --color --graph
  • What is the difference between running git merge master in feature-branch and running git merge feature-branch in master? If you're not sure, run both and check the logs.
  • After doing the merge, if you run git log you'll see the merge commit has a special line saying: merge: commit1 commit2, do you know why?
  • If we git show the merge commit, what content is there? Hint: try running git show HEAD^...HEAD or git diff commit1...commit2
