The basic step when committing to open source projects is to fork the project.
Then the process is easy you create your branch and you make a pull request. However from time to time you need to adjust you branch based on the latest changes.
This is how you sync your fork to the original one.
#set remote if it does not exist. This is the project you forked from git remote add upstream firstname.lastname@example.org:account/project-name.git git fetch upstream git checkout master git merge upstream/master
Synchronize from original Repo
This is pretty easy but you might want something more than just synchronizing with the original repository.
For example there might be a pull request which never got merged for various reasons and you wan’t to pick up from where it was left.
The first step is to add the repository needed
git remote add $remote_repo_identifier $remote_repo_url
So we just added another remote to our repository.
The next step is to fetch the branches from the remote.
git fetch $remote_repo_identifier
Then you can switch to the branch of your choice, continue make a new branch and continue with a pull request.
git fetch $remote_branch
Remove the upstream
git remote remove $remote_repo_identifier
Set upstream to the current repo
git branch -u $remote_repo_identifier/$remote_branch $remote_branch git branch --set-upstream-to=$remote_repo_identifier/$remote_branch $remote_branch
For example change the upstream to the origin one
git push --set-upstream origin $remote_branch
Rebase from original repo
Now that we got the upstream commands in place let’s see how to rebase from the origin fork.
The rebase is a very common thing.
Branch starts from fork code is added, then a merge is getting closed and as expected a rebase is asked because master had some changes.
First let’s add and fetch from the upstream
git remote add upstream http://the-repo git fetch upstream
Then checkout to the branch of your choice and rebase
git checkout branch-under-pr git rebase upstream/master
Once your rebase is successful proceed on pushing
git push -f origin branch-under-pr
