Rebase Integration Strategy

This document outlines a rebase integration strategy, focusing on the steps involved in integrating changes using the rebase and merge option within a GitHub pull request. This strategy is part of the AcostaBSU, CS471WorkflowsHomeworkAssignment and directly references user story #1. Let's dive into the details, guys!

Task Overview

Before we get started, here’s a quick rundown of the tasks we’ll be tackling:

  • [ ] :question: Answer question Task3_Q1 on Canvas
  • [ ] :bust_in_silhouette: Assign yourself to this task (this will prompt the WorkflowLearning GitHub App to create the task_3_rebase branch)
  • [ ] :hourglass_flowing_sand: Wait (at most) 60 seconds until the WorkflowLearning GitHub App will comment on this task and confirm that the branch task_3_rebase was created (refresh the page if you don't see the confirmation comment)
  • [ ] Create a new PR having the base branch master and the compare branch task_3_rebase
  • [ ] Edit the description of the PR to reference this task (i.e., the PR description should contain Closes #3)
  • [ ] :brain: Understand the commits and file changes made in the PR
  • [ ] :question: Answer question Task3_Q2 on Canvas
  • [ ] :arrows_counterclockwise: Refresh this page (to ensure that any commits referencing this task are shown on this page) and scroll all the way to the bottom of the page
  • [ ] :question: Answer question Task3_Q3 on Canvas
  • [ ] In the PR, integrate the changes into master using the Rebase and merge option
  • [ ] :eyes: Inspect the history of all the branches and commits via Insights -> Network
  • [ ] :x: In the PR, use the GitHub interface to delete the branch (since the branch content was successfully integrated into master)
  • [ ] :eyes: Inspect the history of all the branches and commits via Insights -> Network
  • [ ] :arrows_counterclockwise: Refresh this page (to ensure that any commits referencing this task are shown on this page) and scroll all the way to the bottom of the page
  • [ ] :question: Answer question Task3_Q4 on Canvas
  • [ ] :question: Answer question Task3_Q5 on Canvas

Detailed Steps and Explanation

Initial Setup and Branch Creation

First, make sure to assign yourself to this task. This triggers the WorkflowLearning GitHub App to create the task_3_rebase branch. Keep an eye out for a confirmation comment from the app, which usually takes about 60 seconds. If you don't see it right away, just refresh the page. Once the branch is created, you're ready to create a new pull request (PR). The base branch should be master, and the compare branch should be task_3_rebase. Don't forget to edit the PR description to reference this task by including Closes #3. Understanding the commits and file changes in the PR is crucial, so take your time to review them carefully. This initial setup ensures that you have a dedicated space to work on your changes without directly affecting the main codebase. This is a foundational step in any collaborative coding environment, allowing for isolated development and testing before integration.

Understanding the Rebase Strategy

The rebase integration strategy involves taking the changes from your feature branch (task_3_rebase in this case) and reapplying them onto the master branch. This process essentially rewrites the commit history of your feature branch, making it appear as if you branched off from the latest commit on master. This approach helps in maintaining a cleaner and more linear project history. When you initiate the rebase, Git will apply each commit from your feature branch onto the current master branch. If conflicts arise during this process, you'll need to resolve them manually before continuing. The goal is to ensure that your changes integrate seamlessly with the existing codebase. This method contrasts with merging, which creates a merge commit, preserving the history of both branches but potentially leading to a more complex and branched history. Rebasing aims for simplicity and ease of understanding in the long run.

Integrating Changes with Rebase and Merge

Now, let's talk about integrating the changes into master using the Rebase and merge option. This is where the magic happens! When you choose this option in the PR, GitHub will rebase your task_3_rebase branch onto the master branch. This means your commits will be neatly applied on top of the latest master commits. After the rebase, GitHub will then merge the rebased commits into master, resulting in a linear history. The key benefit here is a cleaner, easier-to-follow commit history. However, it's important to note that rebasing rewrites history, which can be problematic if the branch has already been shared with others. In this case, since it's a dedicated task branch, it's perfectly fine. Make sure to resolve any conflicts that arise during the rebase process to ensure a smooth integration. This step is vital for keeping your codebase organized and maintainable.

Post-Integration Steps: Cleanup and Inspection

After the integration, it's essential to inspect the history of all branches and commits. You can do this via Insights -> Network. You'll notice that all commits from the task_3_rebase branch were
