Study Notes
Git Basics
- Definition: Git is a distributed version control system used to track changes in source code during software development.
-
Key Concepts:
- Repository (Repo): A storage space for your project, containing all versions and changes.
- Commit: A snapshot of changes in the repository. Each commit has a unique ID.
- Branch: A parallel version of the repository allowing for feature development without affecting the main codebase.
- Merge: Combining changes from different branches.
- Clone: Creating a local copy of a repository from a remote server.
Git Workflow
-
Common Workflows:
- Feature Branch Workflow: Create a new branch for each feature, allowing for isolated development.
- Git Flow Workflow: A structured branching model that defines roles for branches (feature, develop, release, hotfix).
- Forking Workflow: Used in open-source projects; users fork a repository, make changes, and propose updates via pull requests.
-
Basic Commands:
-
git init: Initialize a new Git repository. -
git clone <repo>: Clone a repository to your local machine. -
git add <file>: Stage changes for the next commit. -
git commit -m "message": Commit staged changes with a descriptive message. -
git push: Upload local commits to a remote repository. -
git pull: Fetch and integrate changes from a remote repository.
-
GitLab Features
- Repository Management: Built-in version control with support for Git repositories.
- CI/CD Pipelines: Continuous integration and deployment tools to automate testing and deployment.
- Merge Requests: Facilitates code review and discussion before merging changes into the main branch.
- Issue Tracking: Manage project tasks and bugs directly within the repository.
- Wiki and Documentation: Collaborative documentation tools for project details.
- Access Control: Granular permission settings for team members and collaborators.
Version Control Best Practices
- Frequent Commits: Commit changes often with meaningful messages to track project evolution.
- Use Branches: Utilize branches for features, bug fixes, and experiments to maintain a clean main branch.
- Pull Requests/Merge Requests: Encourage code reviews and discussion before merging changes.
- Document Changes: Keep a changelog to note significant changes and versions over time.
- Backup Regularly: Ensure remote repositories are regularly updated to prevent data loss.
- Consistent Workflow: Standardize workflows across teams to streamline collaboration and reduce confusion.
Git Basics
- Git is a distributed version control system for tracking changes in source code during software development.
- A repository (repo) is a storage space that contains all versions and changes of a project.
- A commit is a snapshot representing a set of changes in the repository, identified by a unique ID.
- A branch allows for parallel development, enabling feature work without affecting the main codebase.
- Merging combines changes from different branches into one cohesive version.
- Cloning creates a local copy of a repository from a remote server for personal use or modification.
Git Workflow
- Feature Branch Workflow involves creating a new branch for each feature to isolate development efforts.
- Git Flow Workflow is a structured approach that defines specific roles for feature, develop, release, and hotfix branches.
- Forking Workflow is common in open-source projects; users fork a repository, make changes, and propose them through pull requests.
- Basic Git commands include:
-
git init: Initializes a new Git repository. -
git clone: Copies a remote repository to a local machine. -
git add: Stages changes for the next commit. -
git commit -m "message": Commits staged changes with a specified message. -
git push: Uploads local commits to a remote repository. -
git pull: Fetches and integrates updates from a remote repository.
-
GitLab Features
- GitLab provides built-in version control with support for Git repositories and repository management.
- CI/CD Pipelines facilitate automated testing and deployment processes.
- Merge Requests enable code reviews and discussions prior to merging into the main branch.
- Issue Tracking helps in managing project tasks and bugs within the repository.
- A Wiki and documentation tools allow collaborative efforts for project details.
- Access Control allows granular permission settings for team members and contributors.
Version Control Best Practices
- Commit changes frequently with meaningful messages to track the project's progress and evolution.
- Utilize branches for new features, bug fixes, and experiments to maintain a clean and stable main branch.
- Implement pull requests or merge requests to promote code reviews and collaborative discussions before finalizing changes.
- Maintain a changelog to document significant changes and track versions over time.
- Regularly back up remote repositories to prevent potential data loss.
- Standardize workflows across teams to enhance collaboration and minimize confusion.
Version Control System (VCS) Fundamentals
- A Version Control System (VCS) tracks changes in files, enabling collaboration among multiple users.
-
Types of VCS:
- Centralized: Features a single server with all versions; clients must check out files.
- Distributed: Each user maintains a full copy of the repository, exemplified by Git.
-
Key Concepts:
- Commit: Captures a snapshot of changes made to files.
- Repository: A storage location for project files along with their historical changes.
- Clone: The action of copying a repository to a local machine for development.
- Pull: The process of fetching and integrating changes from the remote repository.
- Push: The action of sending local changes from a user's machine to the remote repository.
Branches and Merges
-
Branching:
- Enables parallel development, with each branch serving as a separate line of work.
- Common branch types include:
- Main (or Master): The primary branch containing production-ready code.
- Feature: Created for developing new features without affecting the main branch.
- Hotfix: Aimed at applying quick fixes to address urgent production issues.
-
Merging:
- Combines changes from one branch into another.
- Fast-Forward Merge: Advances the branch pointer; no extra merge commit is created.
- Three-Way Merge: Merges changes from two branches using their common ancestor for reference.
Collaboration Workflows
-
Key Workflows:
- Feature Branch Workflow: Each feature gets its own branch, isolating changes from others.
- Gitflow Workflow: A structured branching model defining specific roles for branches (feature, develop, master, release).
- Forking Workflow: Users create personal copies of the main repository for proposing changes, prominent in open-source projects.
- Pull Requests (PRs): Serve as a formal mechanism for proposing changes, facilitating code reviews and discussions prior to merging into the main branch.
Continuous Integration/Deployment (CI/CD)
- Continuous Integration (CI): Automates the integration of code changes into a shared repository, often coupled with automated testing to maintain software quality.
- Continuous Deployment (CD): Further automates CI by deploying code changes automatically to production after successful tests.
- Tools Associated with CI/CD: Include GitLab CI, GitHub Actions, Jenkins, and CircleCI; these tools streamline building, testing, and deployment processes.
Repository Management
- Repositories: Can be classified as public or private, containing all project-related files and their comprehensive history.
- Access Control: Manages user permissions (read, write, admin) and collaborator access through defined roles and team structures.
- Issue Tracking: Integrated systems that manage bugs and feature requests related to commits, enhancing project management.
- Documentation: Utilizes README files and wikis to provide essential information and guidelines for the project.
