It takes so long and ultimately introduces risk and delays keeping them up to date.This article illustrates committing changes to a different branch in Git. Of course if you make small commits some of them could be ‘cherry picked’ across if appropriate. Merge the branch as soon as possible, or discard it. There is nothing more time consuming and troublesome than having to maintain a long lived feature branch. When all of you have finished and merged your changes to the shared branch, merge it wherever it needs to go. If you find more shared changes you all need, commit them to the shared branch. Then when the task is complete, merge it back to the shared branch. Each branch can have nice small discrete commits pushed to it. Now you and the others working on their own discrete features can branch off this branch for their individual tasks. Don’t forget this is your feature branch. Keep the branch, you don’t need to merge it yet. Each of you need a single change, so how do save having to repeat the work? Simple…Ĭreate a branch, make your shared refactoring changes there. Remember, there are a few of you all working on a feature. Now what about that scenario I talked about earlier. Then when you’re done, merge it (pull request or not) to wherever it needs to go. Generally create a branch for every feature you’re working on. You’ll lose all of the branch information, just as if you committed all the changes directly onto the target branch. You should - in my opinion - always merge a branch into where you eventually want it, never rebase it. These changes might be thrown away, entirely rewritten or in the majority of cases they’ll be promoted into the main history of the codebase - via a merge.Īs a side note, remember the above points when merging branches. Let’s break it down, a branch (aka a feature branch) is designed to encapsulate a group of changes. On the contrary, I’ve come across problems when branches haven’t been used. I have not come across any scenario where creating a branch causes a problem. You can prevent changes to the master or develop branches to ensure each change (group of commits on a branch) goes through a review process (the pull request). For example, GitHub uses branches to encapsulate changes in a pull request. In most cases branching will be mandated by the environment you work in, and the tools you’ll be using. This also relates to branching they’re closely linked. You unblock others, whilst also making merging easier in the future. If you make these in a discrete commit, you can all use the changes without the noise of each person’s individual activities. You may both want or need some refactoring changes. Now imagine a scenario where two (or more) of you are working on a feature. The ultimate goals are to have commits that: What are the benefits, why do we all repeat the same process of experimentation? What could we start doing right from the outset? But why do we all have to figure this out by trial and error. This continues until we have normalised with the other developers we work with. When to commitĪs we go through our careers we typically learn over time to increase how often we commit our changes. There is a ton of information out there about how to do things even why, but what about when? What I’m hoping is that in sharing some of my experience you can understand the benefits of the approach many of my colleagues and I take to good effect. The thing is we all go through this dance on our own. “Those who cannot remember the past are condemned to repeat it” We tend to figure these things out on our own, we try things in all sorts of different ways until we land roughly on an approach that normally resembles what the rest of us (hopefully) do. If my last post was about the why, this one is about the when. But what does this mean…? What is the right frequency? When should branches be used? When do they work well, and when should they be avoided? We’re told that we need to commit early and often.
