Contributing

Here are some guidelines for hacking on artman.

• Please sign one of the Contributor License Agreements below.
• File an issue to notify the maintainers about what you're working on.
• Fork the repo; develop and test your code changes; add docs.
• Make sure that your commit messages clearly describe the changes.
• Make the pull request.

Before writing code, file an issue

Use the issue tracker to start the discussion. It is possible that someone else is already working on your idea, your approach is not quite right, or that the functionality exists already. The ticket you file in the issue tracker will be used to hash that all out.

Fork artman

We will use GitHub's mechanism for forking repositories and making pull requests. Fork the repository, and make your changes in the forked repository.

Include tests

Be sure to add relevant tests and then run them using nox before making the pull request.

Docs will be updated automatically when we merge to master, but you should also build the docs yourself via nox -e docs, making sure that the docs build OK and that they are readable.

Make the pull request

Once you have made all your changes, tested, and updated the documentation, make a pull request to move everything back into the main artman repository. Be sure to reference the original issue in the pull request. Expect some back-and-forth with regards to style and compliance of these rules.

Using a Development Checkout

You’ll have to create a development environment to hack on artman, using a Git checkout:

• While logged into your GitHub account, navigate to the artman repo on GitHub.
• Fork and clone the artman repository to your GitHub account by clicking the "Fork" button.
• Clone your fork of artman from your GitHub account to your local computer, substituting your account username and specifying the destination as hack-on-artman. For example:

cd ${HOME}
git clone git@github.com:USERNAME/artman.git hack-on-artman
cd hack-on-artman

# Configure remotes such that you can pull changes from the artman
# repository into your local repository.
git remote add upstream https://github.com/googleapis/artman.git

# fetch and merge changes from upstream into master
git fetch upstream
git merge upstream/master

Now your local repo is set up such that you will push changes to your GitHub repo, from which you can submit a pull request.

• Check that the Protobuf package is installed by running:

protoc

• If not installed, install the Protobuf package (https://github.com/google/protobuf) and add the installation directory to PATH.
• Create use tox to create development virtualenv in which artman is installed:

sudo pip install virtualenv virtualenvwrapper
# Edit shell startup file to enable virtualenvwrapper, see:
# http://virtualenvwrapper.readthedocs.io/en/latest/install.html#shell-startup-file
mkvirtualenv --python=`which python3` artman
pip install -e .

• This creates a virtualenv named artman that has artman installed. Activate it to use artman locally, e.g, from the python prompt.

cd ~/hack-on-artman
workon artman

Running Tests

• To run the full set of artman tests on all platforms, install nox into a system Python. The nox console script will be installed into the scripts location for that Python. While in the artman checkout root directory (it contains nox.py), invoke the nox console script. This will read the nox.py file and execute the tests on multiple Python versions and platforms; while it runs, it creates a virtualenv for each version/platform combination. For example:

sudo pip install nox-automation
cd ~/hack-on-artman
nox

• To run the full set of artman smoke tests, you need to install docker installed on your machine, and run the following at the root of your artman source directory:

docker pull googleapis/artman:latest
docker run -it \
  -v ${PWD}:/usr/src/artman \
  googleapis/artman:latest \
  /bin/bash -c  "pip uninstall -y googleapis-artman; \
  pip install -e /usr/src/artman/; \
  /usr/src/artman/test/smoketest_artman.py --apis=pubsub,vision"

# Optionally, you can mount your local toolkit for testing:
docker run -it \
  -v ${PWD}:/usr/src/artman \
  -v {REPLACE_WITH_LOCAL_TOOLKIT_DIR}:/toolkit \
  googleapis/artman:latest \
  /bin/bash -c  "pip uninstall -y googleapis-artman; \
  pip install -e /usr/src/artman/; \
  /usr/src/artman/test/smoketest_artman.py --apis=pubsub,vision"

Contributor License Agreements

Before we can accept your pull requests you'll need to sign a Contributor License Agreement (CLA):

• If you are an individual writing original source code and you own the intellectual property, then you'll need to sign an individual CLA.
