Git Stash: Managing Urgent Fixes in a Time Machine Project

Introduction

Imagine you're a developer working on a time machine project. Suddenly, your future self appears and warns you about a critical bug in the current codebase! You need to quickly save your work-in-progress, fix the bug, and then resume your current task. This challenge will test your Git stash skills in a high-stakes, time-bending scenario!

Stash, Fix, and Resume

Initial State

You are in the ~/project directory. The time-machine directory is a new Git repository with the following files:

main-console.txt (content: "Bug: Temporal Flux Unstable")
flux-capacitor.txt (content: "Work in progress")
new-feature.txt (content: "Untracked feature")

You can use the git status command to check the current status of the repository.

Tasks

Stash your current changes, including any untracked files.
Fix the "critical bug" in the master branch by updating the content of main-console.txt to "Fixed: Temporal Flux Stabilized".
Create a new branch from your stashed changes, named future-upgrades.
Ensure the bug fix from the master branch is also present in the future-upgrades branch.

Requirements

All operations must be performed in the ~/project/time-machine directory.
Ensure your original changes (both tracked and untracked) are present in the new branch.
The bug fix in main-console.txt must be present in both master and future-upgrades branches.

Example

After completing the challenge, your repository should look like this:

On the master branch:

main-console.txt (content: "Fixed: Temporal Flux Stabilized")

On the future-upgrades branch:

main-console.txt (content: "Fixed: Temporal Flux Stabilized")  ## Contains the bug fix from master
flux-capacitor.txt (content: "Work in progress")              ## Original tracked changes
new-feature.txt (content: "Untracked feature")                ## Original untracked file

Note: To achieve this state, you'll need to ensure that both branches contain the bug fix while preserving your work-in-progress changes in the future-upgrades branch.

✨ Check Solution and Practice

Summary

In this challenge, you've practiced using Git stash in a simulated emergency scenario. You've learned how to quickly save your work-in-progress (including untracked files), switch contexts to fix a critical issue, and then create a new branch from your stashed changes. These skills are crucial for maintaining a smooth workflow when unexpected tasks arise, allowing you to juggle multiple responsibilities without losing your work or breaking your concentration.

Remember, while Git stash is a powerful tool for temporarily storing changes, it's best used for short-term storage. For longer-term work or significant features, creating dedicated branches is often a better approach. Keep practicing these skills, and you'll be well-equipped to handle any time-bending development scenarios that come your way!
