Mastering git: class 2 lab

Class 3

• Push & pull
• Remotes
• Pull requests

Lab

• find a file with your <UCO>.txt and write down what’s the most valuable thing you learnt so far on this course
• CI needs to pass
• BONUS: contribute also to what_we_learnt.txt (beware of rebase and merge conflicts!)

Class 2

• Branches
• Tags
• Merging
• Stash

Lab

Setup

• Clone this repository (clone it again even if you have a copy locally)
  • Run git branch add-lab-description origin/add-lab-description
  • Run git branch wip-show-sample-commands origin/wip-show-sample-commands
  • These commands will create local copies of branches from remote origin: in this repository

Tasks

• Delete branch “wip-show-sample-commands”
• Does the “add-lab-description” top commit look okay?
  • Fix the problem once you spot it
• Create a new branch that starts from "add-lab-description", name it “fix”
• Oh, that’s not a good branch name, sorry. Rename the branch from “fix” to “fix-add-lab-description”
• Merge fix-add-lab-description into main
• BONUS: push your local main into your fork
• EPIC BONUS: Create a pull request from fix-add-lab-description to this repository

Solution

You are still free to do this task.

Click only when you want to see the solution for this lab with the explanation for commands.

1. Delete the branch: git branch -D wip-show-sample-commands (has to be -D since the branch is not merged).
2. git switch add-lab-description, let's work on the "add-lab-description" branch.
3. There is a typo in README.md, we can fix it easily: workflowwwwwwwwwwwwwwwwwwwwww → workflow.
4. git commit -a -m 'fix typo in readme' - we want to preserve the original commit.
5. git switch -c fix: instructions say to create this branch.
6. Uhhhh, make your mind! 😄 git branch -m fix fix-add-lab-description
7. git switch main && git merge fix-add-lab-description: merged, sweet!
8. In order to push, we need to set up our fork remote, but let's do this properly:

• git remote rename origin upstream: we want our for to be the default and the actual upstream repo to be named "upstream"
• git remote add origin [email protected]:$USERNAME/mastering-git-class2-lab: now to set up our fork
• git fetch --all: let's fetch all refs to be sure we set it up correctly

9. Let's push to our fork's main to see our change: git push origin main:main (we are telling git to push our local branch main into our fork repository and name the branch main there: so basically put our new local commits from main into fork's main)
10. The best practice is to create pull requests from dedicated branches, not main, so let's push again: git push origin fix-add-lab-description:fix-add-lab-description
11. Time to create the PR!
