Git Branching

Use a branch to isolate development work without affecting other branches in the repository. Each repository has one default branch and can have multiple other branches. You can merge a branch into another branch using a pull request.

Branches allow you to develop features, fix bugs, or safely experiment with new ideas in a contained area of your repository.

Git Revert and Reset

Two commonly used tools that git users will encounter are those of git reset and git revert. The benefit of both of these commands is that you can use them to remove or edit changes you’ve made in the code in previous commits.

Git Rebase and Merge

What Is Git Rebase?

Git rebase is a command that lets users integrate changes from one branch to another, and the logs are modified once the action is complete. Git rebase was developed to overcome merging’s shortcomings, specifically regarding logs.

What Is Git Merge?

Git merge is a command that allows developers to merge Git branches while the logs of commits on branches remain intact.

The merge wording can be confusing because we have two methods of merging branches and one of those ways is called “merge,” even though both procedures do essentially the same thing.

Task : Merge Conflict Reslove

Add a text file called version01.txt inside the Devops/Git/ with “This is first feature of our application” written inside. This should be in a branch coming from master, [hint try git checkout -b dev], switch to dev branch ( Make sure your commit message will reflect as "Added new feature"). [Hint use your knowledge of creating branches and Git commit command]

  • version01.txt should reflect at local repo first followed by Remote repo for review. [Hint use your knowledge of Git push and git pull commands here]

Add new commit in dev branch after adding below mentioned content in Devops/Git/version01.txt: While writing the file make sure you write these lines

  • 1st line>> This is the bug fix in development branch

  • Commit this with message “ Added feature2 in development branch”

  • 2nd line>> This is gadbad code

  • Commit this with message “ Added feature3 in development branch"

  • 3rd line>> This feature will gadbad everything from now.

  • Commit with message “ Added feature4 in development branch

Restore the file to a previous version where the content should be “This is the bug fix in development branch” [Hint use git revert or reset according to your knowledge]

Task 2:

For Task 2, you can demonstrate the concept of branches as follows:

Create a new branch from 'master' and make some changes in the 'dev' branch.

git checkout -b dev2 
# Make changes to files in the 'dev2' branch.

Merge the 'dev2' branch into 'master.'

git checkout master git merge dev2

In conclusion, Git branching is a fundamental concept in version control that allows developers to work on separate features or experiments without affecting the main codebase. Common Git commands like revert, reset, rebase, and merge provide the flexibility needed to manage code changes effectively. Understanding these concepts and commands is essential for effective code collaboration and version control in software development.
