![]() To undo that you can drop it from the history.Ĭonsider a series of commits in which you fixed typos. You might have accidentally committed some changes. Here's a quick overview of ways you can change history: Since git commits are record of history, by moving them around we can indeed rewrite history. ![]() Git Rebase essentially allows for moving commits around. Merging feature_branch to Development would now result in a fast-forward merge, which means there will be no conflicts to resolve during the merge. Notice how after rebasing the commit hash changes, this is because git creates new commits behind the screen, and stops pointing to the old commits. By rebasing feature on Development, all the commits of the feature branch will be replayed on top of the latest commit in the Development branch. To avoid conflicts during merge, we try to ensure that the HEAD of your feature branch is on top of the latest commit in the Development branch.īranch feature and branch Development have one commit each and therefore in git terms, have diverged. Let's look at a few scenarios.Īs we saw in Part 1 of this series, teams that follow git, feature branches are merged onto the Development branch. ![]() This command allows you to be able to move your commits, making this a very powerful command, used for different purposes. Git rebase applies your commits on top of another branch's tip. If not provided, it defaults to 0, which is the latest stash. pop, apply and drop take an optional parameter.Ensure your working directory is clean before applying changes from stash.Use git stash to temporarily put away your changes when checking out a new branch.When you want to clear the entire list, use git stash clear. Use this command when you want to delete an outdated stash from you list. The stash remains the same after using apply. Notice how the stash is empty after popping. pop removes the stash before applying it, apply does the same but doesn't remove the change set from the stash. There are two ways to do this: git stash pop and git stash apply. Let's find out how we can retrieve changes from a stash to the working directory. git stash show -p shows the exact diff that is stashed. Git stash show summarises the stashed changes. It's what it sounds like, this commands lists down all the changes you stashed. Notice how after running git stash, the working directory becomes clean, that's because all the changes have been pushed elsewhere. Git stash push -m "Upgrading version" does just that. To start off you'd need to clean your working directory, and save your existing changes somewhere safe. Imagine a scenario, where you started working on a feature, but you're not nearly ready to commit these changes, and your teammate asks you to work on a different feature branch, because it is of higher priority. So in between all these stages, git stash pushes all the changes in the working directory to a special directory called stash. From there when git commit they are moved to the repository.Changes you git add are moved to a staging area. ![]() When you checkout or make new changes they live on the working directory.It helps to understand about the three stages, that your changes are moved to and from in a git repository, before we dive into git stash. While working in a team, there might be situations where you'd have to temporarily put away your current work, to work on something of higher priority, and git stash helps you stash your work away and clear your working directory. Part 2 is about git stash and git rebase - two commands I use regularly when collaborating on tasks. Part 1 covered how to set up git for your project, so you can collaborate better. The series aims to provide examples of using lesser known git commands that improve development experience and reduce friction during collaboration across the team. Note: This series assumes the reader is familiar with using the command line and has used basic git commands during development. ![]()
