Push changes to master git code#
Create a name for a new temporary branch (e.g.In early 2013, SparkFun made the decision to share all of the code and design files for our products via GitHub.Open the branches/tags switcher in GitHub’s web UI.Compose a URL, where deadbeef is the hash of the last good commit to the damaged branch.Open this feed and look for something like this: an hour ago Of course, you also can’t fetch them, but there is a workaround.īut, note that this will only work if you are “watching” the repository (meaning that everything happening in it appears in a feed displayed on your GitHub’s front page). We will benefit from the fact that GitHub does not immediately remove unreachable commits. Nevertheless, keep calm and ask your teammates to stay off the remote for a while. You can no longer do git push -force sha1:master because you do not have the recent commits locally (and you can’t get them with git fetch because they no longer belong to any branch). So, let’s say that just before you performed git push -force, someone had closed a bunch of pull requests, and so master now looks nothing like your local copy. Case 2: master was changed by someone else before you messed up Now, it’s time to learn from your mistakes. $ git push -force origin deadbeef:masterĬongratulations! You’ve saved the day. So all you need is to… force push (fighting fire with fire!) this commit back to the master branch, on top of the bad one. In this case, deadbeef is your last good commit to the master just before you inflicted this unfortunate damage. The first group of symbols (which looks like a commit’s SHA prefix) is the key to pulling off this rescue operation. Inside your shell, look at the output of git push -force and try to locate a line that resembles this one: + deadbeef.f00f00ba master -> master (forced update)

Ask people not to mess with the repo for the next minute or so while you’re fixing things. First, go into your team’s chat and confess your sins. Just do not close or clear your terminal. Good news! You have everything you need to undo your mistake before your very eyes. But what if you’re not so lucky? Then, read on! Case 1: You were the last person to push to master before the mistake If you’re lucky, their local repository will have the full history of commits, your mistake will be overwritten with fresh code, and nothing will be lost. Here, all you have to do is to go into your team chat and ask this person to force push their recent changes. However, as one excellent guide tells us, DON’T PANIC! The upside is, you’re using git, and that means everything can be fixed.īest case scenario: someone else working on the same code pulled a recent version of the master branch just before you broke it. Oops! In the blink of an eye, your teammates have lost all their latest work. After a long day of work, it could be incredibly easy to execute git push -force instead of the usual git push -force deis master. That could happen, for instance, when deploying with Heroku, which use separate git remotes to build and deploy an application. While working with several remotes in the same git repository, you will eventually git push -force into master (or another important branch that should’ve never been messed with). Sooner or later, this is going to happen. If you’re thinking this doesn’t sound like something you’d do, well, let’s not get overly confident. In this tutorial, we’ll show you how to quickly recover from an unfortunate git push -force.
