Forking off master

When you fork a branch, never touch the fork’s master again. Just leave it as a moment in time. Never pull or push to it.

When you need to do work, simply:
– go to your fork
– create a branch
– then pull upstream from the real master

That will give you an up-to-date local master. And you can then create your local branch and it will always be ready for work.

You can check the branch in against your fork. But never touch the fork master. Just let ghe create the PR and merge to upstream master from there.

How to rebase

git checkout master
git pull upstream master
git checkout branch
git rebase master
CONFLICT Resolve by looking for <<<<<<< HEAD
git add <conflicted file>
git rebase --continue
git rebase --skip (if there are submodules/commits you want to skip)
git push --force -n

Here you can see an example of resolving a rebase conflict and being part way through.
The green files are files that have not yet been rebased.
The red file is the one you just resolved the conflict on.
While you rebase –continue the green files will be rebased too.

If you get something dirty just

rm -rf <component>
git checkout <component>
