How to turn a git branch into fork?

问题

I have created a branch in my GitHub repo: https://github.com/markmnl/FalconUDP, so there are now two branches: "master" and "single-threaded". I realise now I will never want to merge "single-threaded" back into "master" and want to maintain each branch separately independently of one another, though from time-to-time I will want to cherry pick bits of code from one into the other.

It would be disastrous should the branches be accidentally merged (though not catastrophic of course since I can always go back - it being in source control).

It strikes me what I should have done is fork the project into another repo. (That way I can still do the cherry picking with Pull Requests).

What should I do now?

I guess your question is specifically: how to create a fork of your own project in the same user account in GitHub. You cannot use the user interface of the website, but you can create a new repository and push the relevant branches to it:

Create new repo, completely empty, without even a README https://github.com/new
Add the new repo as a new remote in your local clone of the original project, let's call this remote fork for example:
```
git remote add fork NEW_REPO_URL
```
Push your single-threaded branch to it:
```
git push -u fork single-threaded
```
Delete this branch from the original project, assuming your remote is called origin:
```
git push origin :single-threaded
```

Here's how I would do it:

Fork FalconUDP into a new repository (using the fork feature on GitHub)
Clone the new repository (FalconUDP-st?) locally
merge the single-threaded branch back into master
delete the single-threaded branch
push back to FalconUDP-st on GitHub

You can issue pull requests on the GitHub website, or you can just cherry pick across your local clones.

If you really want to fork, the way would be:

Clone FalconUDP
in the clone, checkout single-threaded branch

Now you have two options:

a) new remote repo

Create new repo
Add it as remote to cloned repo, call it, let's say "new-remote"
git push single-threaded new-remote/master
New repo has contents of single-threaded as master

b) Local repo

delete branch master
checkout from branch single-threaded into new branch master
