Local Portfile Repositories (especially step 5) in the documentation for instructions on how to handle a local repository If you use this as your working local repository check 4.6. $ git clone of these create a macports-ports directory containing a working tree at the latest commit, with the repository itself-with full history-at macports-ports/.git. GitHub allows cloning over HTTPS or SSH: Obtaining a local copy of a Git repository is called "cloning" because you usually end up with a carbon copy of the source repository. Also check that the Trac preferences have the correct email address. $ git config user.email get proper attribution for your commits on GitHub, please add and verify this email address in the GitHub settings. You can override your global settings by modifying /path/to/MacPorts/repo/.git/config: $ git config -global user.email you're a MacPorts committer, you should use your MacPorts email address while working in MacPorts repositories. $ git config -global user.name 'Foo Barbaz' You will likely use your name and a personal email address for most Git projects, so you can add them to $HOME/.gitconfig: Git commits identify authors and committers by name and email address.

In this article, you learned about merge commits and how you can avoid them when syncing your fork in Git using git rebase. The pull command will be: $ git pull -rebase upstream master You can skip the git fetch step by using git pull which is git fetch + git merge but with the -rebase flag to override the git merge. You may need to force the push with “ -force.” $ git push origin master -force Then finally, push the updates to your remote fork. Next, you rewrite your fork’s master with the upstream’s master using git rebase. In this step, you fetch all the branches of the remote upstream with: $ git fetch upstream In the above, upstream refers to the original repository from which you created the fork. If you run $ git remote -v, you will see the following: origin (fetch) One for your fork and one for the original codebase. To avoid merge commits, you need to rebase the changes from the original remote codebase in your local fork before pushing them to your remote fork by following the steps below.Ĭreate a link with the original remote repository to track and get the changes from the codebase with the command below: $ git remote add upstream Īfter running the above command, you will now have two remotes. How to avoid merge commits when syncing a fork in Git. Next, you will learn how to avoid it when syncing your fork with an original codebase. Here is the link to the merge commit to the image. The annotated section in the image above shows a merge commit of two parent commits. This merge commit can cause conflicts and mess up a project’s Git history if present in a merged PR. When you create a merge commit, Git automatically merges the histories of two separate commits. But there is one thing unique about a merge commit: it has at least two parent commits. how to avoid them with git rebase when syncing a fork with an original codebase.Ī merge commit is just like any other commit, it is the state of a repository at a point in time plus the history it evolved from.But with a PR open, syncing your fork that way will introduce an unwanted merge commit to your PR. To sync your fork with the original codebase, ideally, you would use the web UI provided by your Git hosting service or run a git fetch and git merge in your terminal, as indicated in this Github tutorial. After you create a PR, there are chances that during its review process, commits will be made to the original codebase, which will require you to sync your fork. To propose changes, you open up a Pull Request (PR). Whenever you work on open source projects, you usually maintain your copy (a fork) of the original codebase.
