Sometimes when contributing to an upstream source, you need to re-base your own repository to be sure there won’t be any conflicts. This is just a very quick and dirty way to do it. I will rewrite this post to be more detailed soon.
The following assumes that you have origin set as your source fork, and upstream set to the original source repository.
Typically this is done similar to;
mkdir rustc && cd rustc git clone email@example.com:luke-nukem/rust.git . git remote add upstream https://github.com/rust-lang/rust.git
The first thing to do is see what the state of your local repository is with
Your branch is up-to-date with 'origin/master'. Changes not staged for commit: (use "git add <file>..." to update what will be committed) (use "git checkout -- <file>..." to discard changes in working directory) modified: _posts/2016-02-27-post.markdown no changes added to commit (use "git add" and/or "git commit -a")
If you have changes pending, rather than
git commiting them, run
stash; this will store your changes on the stack.
Saved working directory and index state WIP on master: 6267421 Initial commit HEAD is now at 6267421 Initial commit
You can now run
git pull --rebase upstream master which will revert you to
a clean copy of upstream.
From github.com:Luke-Nukem/Luke-Nukem.github.io * branch master -> FETCH_HEAD Current branch master is up to date.
git stash list to view the
git stash apply to reapply the most recently stashed work, which you
can then commit with
git commit. You can also branch a stash with
stash branch testbranch.
Now that you’re at a clean state which is equal to upstream minus the changes you committed to your local repo, you can push to your fork origin with;
git push origin master
And now on GitHub, you can make a pull request to the upstream source.
