Git and Project Workflow

10 Lektionen in dieser Stufe

1. Tracking Changes with git init, add and commit
   Record snapshots of a project with meaningful messages. · Lab: Put the sensor project under Git and make three small, well-described commits.
2. Reading History and Undoing Mistakes
   Inspect diffs and safely revert or restore changes. · Lab: Break the program on purpose, find the change with git diff and git log, and undo it.
3. Branching and Merging for Experiments
   Try ideas on a branch and merge or discard them. · Lab: Add a feature on a branch, merge it and resolve one deliberate conflict.
4. Ignoring Secrets and Generated Files
   Keep passwords, venvs and data out of the repository. · Lab: Write a .gitignore, move a secret into an untracked file and confirm git status is clean.
5. Pushing to a Remote Repository over SSH
   Publish a repository to a hosting service or a bare repository on another machine. · Lab: Create a remote, add a deploy key and push the project.
6. Deploying to a Pi with git pull
   Update a device from the repository and restart its service in one step. · Lab: Write a deploy script that pulls, installs requirements and restarts the unit.
7. Pinning Dependencies with Requirements Files
   Rebuild an identical environment on any Pi. · Lab: Freeze the venv, recreate it from scratch on a second card and run the program.
8. Unit Testing Hardware Code with Mock Pins and pytest
   Test GPIO logic on any computer using gpiozero's mock pin factory. · Lab: Write tests that press a mock button and assert the LED state.
9. Editing on the Pi from a Laptop over Remote SSH
   Use a desktop editor against files that live on the Pi. · Lab: Open the project through a remote SSH editor session, set a breakpoint and step through a sensor read.
10. Tagging Releases and Keeping a Changelog
    Mark known-good versions and describe what changed. · Lab: Tag v1.0.0, write a changelog entry and roll the Pi back to the tag.

Abschlussprojekt
