Merge Branches To Develop: A Guide

Hey Agustin and Nati!

So, we've got a bit of a branching situation going on, and it's time to wrangle those branches together! This might sound a little intimidating if you're new to the whole version control thing, but trust me, it's a crucial part of teamwork in software development. We need to merge our individual work – that's each of your branches – into the develop branch. Think of it like combining all the different pieces of a puzzle to see the bigger picture. Let's break down why this is important and how we're going to do it.

Why Merge Branches?

Merging branches is a fundamental practice in collaborative software development, and it's essential for keeping our project organized and moving forward smoothly. Imagine we're building a house, right? Each of us might be working on different rooms – Agustin on the kitchen, Nati on the living room, and maybe someone else on the bedrooms. Each of these rooms is like a separate branch, allowing us to work independently without stepping on each other's toes. But at some point, we need to put all those rooms together to form the complete house. That's where merging comes in!

Think of the develop branch as the blueprint for our current version of the house. It's where all the completed rooms come together before we build the final version (which would be our main or master branch). By merging our feature branches into develop, we ensure that everyone has access to the latest changes, we can test the integrated features, and we can catch any potential conflicts early on. Conflicts are like finding out that the plumbing in the kitchen clashes with the wiring in the living room – it's much easier to fix these problems when we're still in the blueprint stage than when the walls are already up!

Why is it so important to keep the develop branch up-to-date? Well, imagine if we all kept working on our separate rooms without ever checking in with each other. We might end up building walls that don't quite line up or using different materials that don't match. By regularly merging into develop, we ensure that we're all working from the same foundation and that our individual contributions fit together seamlessly. It also makes it easier to track progress, identify bugs, and collaborate effectively. So, merging isn't just a technical step; it's a key ingredient for successful teamwork and a high-quality final product.

Avoiding Integration Headaches

One of the biggest benefits of merging frequently is that it helps us avoid what we call "integration hell." This is when you wait too long to merge your changes and end up with a massive, tangled mess of conflicts that are incredibly difficult to resolve. Think of it like letting your laundry pile up for weeks – the bigger the pile, the more daunting it is to tackle. By merging regularly, we keep the changesets small and manageable, making it much easier to identify and resolve any conflicts that arise. This not only saves us time and frustration but also reduces the risk of introducing bugs into the codebase.

Collaboration and Knowledge Sharing

Merging branches isn't just about combining code; it's also about collaboration and knowledge sharing. When we merge our changes, we're essentially sharing our work with the rest of the team. This allows others to review our code, provide feedback, and learn from our approach. It also helps to ensure that everyone is aware of the latest features and changes, which is crucial for effective teamwork. By working together and sharing our knowledge, we can build better software and grow as developers.

Continuous Integration

Merging is also a key part of the Continuous Integration (CI) process. CI is a practice where we automatically build and test our code every time changes are merged. This helps us to quickly identify and fix bugs, ensuring that our codebase is always in a releasable state. By merging our branches into develop, we trigger the CI pipeline, which runs a series of tests to verify that our changes haven't introduced any regressions. If the tests pass, we can be confident that our code is ready to be integrated into the main branch. If the tests fail, we know that we need to investigate further and fix the issues before proceeding. CI is a powerful tool for improving software quality and reducing the risk of releasing buggy code.

The Game Plan: Merging into `develop`

Okay, so we know why we need to merge, but how do we actually do it? Don't worry, it's not as scary as it sounds! We'll be using Git, which is a version control system that helps us manage changes to our code. Think of Git as a time machine for our project, allowing us to track every change, revert to previous versions, and, of course, merge branches.

Before we dive into the specific commands, let's outline the general steps involved in merging branches:

Make sure your local branch is up-to-date: This is super important! Before you start merging, you want to make sure you have the latest version of the develop branch on your local machine. This helps minimize conflicts and makes the merging process smoother. Think of it like making sure you have the latest version of the blueprint before you start building.
Switch to your feature branch: This is the branch where you've been working on your specific feature or bug fix. We need to be on this branch to start the merging process.
Merge develop into your feature branch: This is where we bring the latest changes from develop into your branch. This step helps us identify any potential conflicts early on. It's like checking if your room design clashes with the latest blueprint updates.
Resolve any conflicts: If there are any conflicts, we need to resolve them manually. This involves carefully reviewing the conflicting code and deciding which changes to keep. Think of it like figuring out how to adjust the plumbing to fit the new wiring layout.
Push your updated feature branch: Once you've resolved any conflicts, you'll need to push your updated branch to the remote repository. This makes your changes available to everyone else on the team.
Create a pull request: A pull request is a request to merge your changes into another branch, in this case, develop. This gives your teammates a chance to review your code and provide feedback before it's merged.
Get your pull request reviewed: This is a crucial step! Getting your code reviewed by others helps to catch potential bugs and ensures that the code meets our quality standards. Think of it like having a structural engineer review your room design before you start construction.
Merge your pull request: Once your pull request has been reviewed and approved, you can merge it into develop. Congratulations, you've successfully merged your changes!

Step-by-Step Instructions

Okay, let's get down to the nitty-gritty. Here's a step-by-step guide to merging your branch into develop using Git:

Update your local develop branch:

First, let's switch to the develop branch locally:
```
git checkout develop
```
Then, pull the latest changes from the remote repository:
```
git pull origin develop
```
This ensures that your local develop branch is up-to-date with the latest changes from the remote repository. We use git checkout develop to switch to the develop branch. The command git pull origin develop fetches and merges changes from the remote 'origin' repository's develop branch into your local develop branch.
Switch to your feature branch:

Now, let's switch to your feature branch. Replace <your-branch-name> with the actual name of your branch:
```
git checkout <your-branch-name>
```
The git checkout <your-branch-name> command switches your working directory to the branch where you've been implementing your feature, ensuring you're working within the correct context for merging.
Merge develop into your feature branch:

This is where we bring the latest changes from develop into your branch. This step helps us identify any potential conflicts early on:
```
git merge develop
```
With git merge develop, you integrate the changes from the develop branch into your current branch. This is a crucial step in identifying any conflicts early and ensuring your feature is compatible with the latest codebase.
Resolve any conflicts:

If there are any conflicts, Git will let you know. You'll need to open the conflicting files and manually resolve the conflicts. Look for special markers like <<<<<<<, =======, and >>>>>>> that indicate the conflicting sections. Carefully review the code and decide which changes to keep. Once you've resolved the conflicts, save the file and stage the changes:
```
git add <conflicted-file>
```
After resolving conflicts, git add <conflicted-file> stages the resolved file, marking it as ready to be committed. This command is essential to include the resolved changes in your merge commit.
Commit the merge:

Once you've resolved all the conflicts, you can commit the merge:
```
git commit -m 
```
