In our previous article agile Lookout on Branching and Merging,’ we have seen that version control system and common base commit is important with types of branching and merging. Git is one of the most powerful versions of the control system used for branching and merging. In this, we will learn Git branching and Git merging tools required and best practices guidelines.

Git Branching and Git Merging

It allows developers to differ from the production of code to fix a bug or add a feature. The main branch is the first branch created when git respiratory is originated using a gitinit command. Developers create branches working with a copy of code without changing the version of the existing. Then branches are created to isolate the code change. These are tested before merging into the main branch. Git identifies the snapshot when a new commit is created and a pointer is also created to the commit where the main branch is. New pointers are created to track the changes when a new commit is created in a new branch. Every branch keeps the track of its versions.

While merging, put local respiratory along with git respiratory and then add origin to the Github respiratory further with single command creating a name for your local branch same of the main branch. By git push command, the git hub respiratory is updated with your local respiratory. By more merging of the unrelated history creation of new respiratory is completed and hence merging.

Tools for Branching and merging
• PowerShellGit client install in system
• GitHub account
• Connect GitHub with SSH
• Project Files (Required while merging)

Best Practices Guide

Review code before committing it
Git suggests committing code git commit without explaining what it does, causing the most useful feature to be ignored. Git also introduces a new tool to version control known as “index” which indicates what to include in the next commit which may be important or even granular. To include this git add –patch tool is used asking whether to commit or not causing larger or small changes. So, it’s always better to review the code and every step before committing.

Don’t rebase shared commit
Rebase is rewriting the history of a branch into something new which is a very powerful as well as dangerous way. It complicates the actual development history of a branch. Instead of rebasing entirely, it is wise to never rebase commits ensuring to not break anyone’s code in our branch.

Not delete unmerged remote branches
In Git, git branches are only pointers to commit and if not pointed will be removed by the garbage collection process. Instead of deleting it’s better to merge the obsolete branch so that old changes are available for reference.

Make Git toolbox your own
As gits are extensible and configurable it is better to add custom git commands as per one’s requirement.

These are tools and guidelines used in Git branching and merging. Familiarize with the ones useful to you and ease the work.
