Compatibility

WaterButler is compatible with Python 3.6.

Documentation

Documentation available at https://waterbutler.readthedocs.io/en/latest/

Setting up

In order to run WaterButler, you must create a Python 3.6-based virtualenv for it.

For MacOSX, you can install the latest version of Python3 using:

brew install python3

For Ubuntu users:

apt-get install python3.6

After completing the installation of Python 3.6, you must create a virtual environment. This can be done with the following commands:

pip install virtualenv
pip install virtualenvwrapper
mkvirtualenv --python=python3.6 waterbutler

pip install setuptools=37.0.0
pip install invoke==0.13.0

invoke install
invoke server

The above code will get the virtualenv up and running for the first time. After the initial setup, you can run waterbutler by running:

workon waterbutler
invoke server

Some tasks also require a running celery worker. You will need to install rabbitmq and run a server:

brew install rabbitmq
# on Ubuntu:
# apt-get install rabbitmq-server
rabbitmq-server

Then in your WaterButler virtualenv:

invoke celery

Configuring

WaterButler configuration is done through a JSON file (waterbutler-test.json) that lives in the .cos directory of your home directory. If this is your first time setting up WaterButler or its sister project, MFR, you probably do not have this directory and will need to create it:

mkdir ~/.cos

The data in waterbutler-test.json is used by the many Django-style settings.py files sprinkled about. Most of these files define a top-level key that its specific configuration should be listed under. For instance, if you wanted your local WaterButler server to listen on port 8989 instead of the default 7777, you would check the settings file for waterbutler.server. That file looks for HOST and DOMAIN configuration keys under the SERVER_CONFIG top-level key. Your configuration file would need to be updated to look like this:

{
  "SERVER_CONFIG": {
    "PORT": 8989,
    "DOMAIN": "http://localhost:8989"
  }
}

If you then wanted to update the GitHub commit message WaterButler submits when deleting files, you would look in waterbutler.providers.github.settings. The DELETE_FILE_MESSAGE parameter should come under the GITHUB_PROVIDER_CONFIG key:

{
  "SERVER_CONFIG": {
    "PORT": 8989,
    "DOMAIN": "http://localhost:8989"
  },
  "GITHUB_PROVIDER_CONFIG": {
    "DELETE_FILE_MESSAGE": "WaterButler deleted this. You're welcome."
  }
}

Testing

Before running the tests, you will need to install some additional requirements. In your checkout, run:

workon waterbutler
invoke install --develop
invoke test

Known issues

• Updated, 2018-01-02: WB has been updated to work with setuptools==37.0.0, as of WB release v0.37. The following issue should not happen for new installs, but may occur if you downgrade to an older version. Running invoke install -d with setuptools v31 or greater can break WaterButler. The symptom error message is: "AttributeError: module 'waterbutler' has no attribute '__version__'". If you encounter this, you will need to remove the file waterbutler-nspkg.pth from your virtualenv directory, run pip install setuptools==30.4.0, then re-run invoke install -d.

• invoke $command results in '$command' did not receive all required positional arguments!: this error message occurs when trying to run WB v0.30.0+ with invoke<0.13.0. Run pip install invoke==0.13.0, then retry your command.
