Documentation

Note: https://readthedocs.org/ is currently unable to build documentation for Python 3.5 projects. The documentation available at https://waterbutler.readthedocs.io/en/latest/ is outdated (v0.15.1). For the most up-to-date documentation, build locally. Within your checkout, run:

pip install -r doc-requirements.txt
cd docs
make
open _build/html/index.html

Setting up

In order to run WaterButler, you must create a Python 3.5-based virtualenv for it.

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

brew install python3

For Ubuntu users:

apt-get install python3.5

After completing the installation of Python 3.5, you must create a virtual environment. This can be done with the following commands:

pip install virtualenv
pip install virtualenvwrapper
mkvirtualenv --python=python3.5 waterbutler
pip install invoke==0.11.1
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

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

A minimal config file would be:

{
  "SERVER_CONFIG": {
    "DEBUG": false
  }
}

That flag is necessary because Python 3.5's asyncio has a bug that is triggered by turning on debugging in Tornado. If you are upgrading from the 3.4-based WaterButler, change that setting in your waterbutler-test.json. If you do not, you will encounter this error:

TypeError: throw() takes 2 positional arguments but 4 were given

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",
    "DEBUG": false
  }
}

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",
    "DEBUG": false
  },
  "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
