Remotes

First configure your remotes so that origin -> your fork and upstream -> main package:

$ git remote add upstream https://github.com/aws/aws-parallelcluster.git

Confirm they are setup properly:

$ git remote -vv
origin  https://github.com/sean-smith/aws-parallelcluster.git (fetch)
origin  https://github.com/sean-smith/aws-parallelcluster.git (push)
upstream        https://github.com/aws/aws-parallelcluster.git (fetch)
upstream        https://github.com/aws/aws-parallelcluster.git (push)

Branches for days

The first step before coding is to create a branch, it's helpful to branch off upstream/develop so git will tell you when the branch is out of sync.

$ git checkout -b super-awesome-feature upstream/develop

Now write some code

One feature one commit

Squash all the commits into one commit. Each feature should be one commit.

Then you can rebase & squash:

git fetch upstream && git rebase upstream/develop
git rebase -i upstream/develop

Then change pick to squash for all but 1 commit, for example:

Magical Tox

Next run tox -e cfn-autoformat to make travis happy:

pip install tox
cd cli && tox -e cfn-autoformat

Test your changes with tox

cd cli && tox

Commit the changes and force push:

git commit -a --amend
git push origin [your_branch] --force
