Study Notes

Git Overview

Git is the de-facto standard for Version Control Systems (VCS) today.
Created by Linus Torvalds (Linux creator) in 2005.
Git supports non-linear development (thousands of parallel branches) and is fully distributed.

Git Basic Concepts

Git does not need a Centralized Repository to work.
Every user maintains a local repository of their own.
Local repositories contain original work, user's own work, and selected work from others.
Users can commit and update their local repository without interference from others.

Git Repositories

There are two types of repositories: Local and Remote.
Local repositories are owned by each user.
Remote repositories are centralized locations accessible to all users, serving as a single source of truth.

Git Best Practices

Break down big features into smaller ones and add them one at a time.
Keep commits atomic, focusing on one part of the feature.
Commit often, even if the work is not done.
Pull changes from the origin/main branch before creating a new branch from local/main.

Git General Best Practices

Push local feature branch commits to Remote often, even if unfinished.
Use branches to organize work.
Write good commit messages to help others.
Select one branching strategy (Git Workflow) and stick with it.

Git Branching

Create a branch for each feature, avoiding multiple features in a single branch.
Ideally, only one person should work on one feature branch.
Feature branches should be short-lived and deleted after merging to the master branch.
Merge early and often to avoid merge conflicts.
Keep the master branch clean, only containing production-ready code.

Additional Topics

Continuous Integration and Continuous Deployment (CI/CD)
Compare Trunk based development workflow with GitFlow workflow
Pull Requests (PRs) for collaborating on changes

Description

Test your knowledge on how proposed changes are handled in Git through feature branches and Pull Requests. Understand the process of verifying, accepting, and merging changes from feature branches to the main branch.
