Types of Contributions

Report Bugs

Report bugs at https://github.com/galaxyproject/pulsar/issues.

If you are reporting a bug, please include:

  • Your operating system name and version, versions of other relevant software such as Galaxy or Docker.
  • Links to relevant tools.
  • Any details about your local setup that might be helpful in troubleshooting.
  • Detailed steps to reproduce the bug.

Fix Bugs

Look through the GitHub issues for bugs. Most things there are up for grabs but the tag “Help Wanted” may be particulary good places to start.

Implement Features

Look through the GitHub issues for features (tagged with “enhancement”). Again, most things there are up for grabs but the tag “Help Wanted” may be particulary good places to start.

Write Documentation

Pulsar is cronically under documented, whether as part of the official Pulsar docs, in docstrings, or even on the web in blog posts, articles, and such.

Submit Feedback

The best way to send feedback is to file an issue at https://github.com/galaxyproject/pulsar/issues.

If you are proposing a feature:

  • Explain in detail how it would work.
  • Keep the scope as narrow as possible, to make it easier to implement.
  • This will hopefully become a community-driven project and contributions are welcome :)

Get Started!

Ready to contribute? Here’s how to set up pulsar for local development.

  1. Fork the pulsar repo on GitHub.

  2. Clone your fork locally:

    $ git clone git@github.com:your_name_here/pulsar.git
    
  3. Install your local copy into a virtualenv. Assuming you have virtualenv installed, this is how you set up your fork for local development:

    $ cd pulsar/
    $ virtualenv .venv
    $ . .venv/bin/activate
    $ pip install -r requirements.txt
    $ pip install -r dev-requirements.txt
    

    If you have something like Slurm or Grid Engine configured on your local machine - you should also install drmaa with pip install drmaa.

  4. Create a branch for local development:

    $ git checkout -b name-of-your-bugfix-or-feature
    

    Now you can make your changes locally.

  5. When you’re done making changes, check that your changes lint:

    $ make lint
    

and ensure the tests look good. The easiest way to test is with Docker if it is available (given the need to test commands with DRMAA, condor, sudo, etc…).:

$ docker run -v `pwd`:/pulsar -t jmchilton/pulsar_testing

This will mount your copy of pulsar in a Docker container preconfigured with all optional dependencies needed to run a wide range of integration tests. If Docker is to much of an ordeal many of Pulsar’s tests can be executed by simply running nosetests from within an virtualenv configured as explained above.:

$ make tests
  1. Commit your changes and push your branch to GitHub:

    $ git add .
    $ git commit -m "Your detailed description of your changes."
    $ git push origin name-of-your-bugfix-or-feature
    
  2. Submit a pull request through the GitHub website.

Pull Request Guidelines

Before you submit a pull request, check that it meets these guidelines:

  1. If the pull request adds functionality, the docs should ideally be updated. Put your new functionality into a function with a docstring. (Until the @jmchilton learns to do this consistently this is only a suggestion though.)
  2. The pull request should work for Python 2.6, 2.7, and 3.4. Check https://travis-ci.org/galaxyproject/planemo/pull_requests and make sure that the tests pass for all supported Python versions. The tests are imperfect and Travis sometimes fails in a transient fashion so this also isn’t strictly required to pass.
