PART 6 of my Git Tutorial Series... (More videos to come in the future)

This is the SIXTH video in a series of videos on Git, the fifth video can be found here:

In this particular video (Part 6) I explain about how a any contributor to a codebase SHOULD integrate their new bug fix or feature code into the "main" production code (usually the master branch). Users should NEVER push their changes directly to the master branch, and infact usually their are security measures in place on the online git repositories providers (like Github, Bitbucket & Gitlab) to stop direct master pushes, instead users should work on a separate branch and use a feature called a PULL REQUEST to ask for their code changes to be brought into the master branch (or the specified destination branch).

The Pull Request feature/capability is something that is carried out on the website of your specified online git repo provider and is incredibly simple to do. The code author creates said pull request with a brief message about what their code achieves and then the pull request can be used by other members of the team or project to "Review the code" before it is accepted into that all important master/production branch. This checking process is called a CODE REVIEW.

Code reviews are "as-it-says-on-the-tin" another member of your team, literally looking at the code you have submitted in your Pull Request and checking it for anything that might stop it from being successful code or successfully being part of the destination branch. The code review is made possible because of the visually easy to understand CODE DIFFS that are provided by the online git repo provider (Github/Bitbucket etc...). These code diffs enable someone else to quickly and efficiently see all the differences that your branch will bring. Allowing for quick feedback and hopefully approval of the pull request.

Pull requests and Code reviews are something that all software development teams (that collaborate on a single codebase) do or very much should do. It is a way of adding safety to the code integration process and of course lets other devs on the team keep up-to-date on what is changing over time in the code. It is an incredibly important process and should never be skipped! Plus a code review is a really nice way of learning where your code could be made better as a by-product!

There are no new terminal commands in this video, instead all of the action is happening within the web browser, on our selected online git repo provider; Github.com
