Please read How to write the perfect pull request for some tips on contributing to open source projects. Although the article is not authoritative, it was authored by the maintainer of Setuptools, so reflects his opinions and will improve the likelihood of acceptance and quality of contribution.
Setuptools is maintained primarily in Bitbucket at this home. Setuptools is maintained under the Python Packaging Authority (PyPA) with several core contributors. All bugs for Setuptools are filed and the canonical source is maintained in Bitbucket.
User support and discussions are done through the issue tracker (for specific) issues, through the distutils-sig mailing list, or on IRC (Freenode) at #pypa.
Discussions about development happen on the pypa-dev mailing list or on IRC (Freenode) at #pypa-dev.
Before authoring any source code, it’s often prudent to file a ticket describing the motivation behind making changes. First search to see if a ticket already exists for your issue. If not, create one. Try to think from the perspective of the reader. Explain what behavior you expected, what you got instead, and what factors might have contributed to the unexpected behavior. In Bitbucket, surround a block of code or traceback with the triple backtick “```” so that it is formatted nicely.
Filing a ticket provides a forum for justification, discussion, and clarification. The ticket provides a record of the purpose for the change and any hard decisions that were made. It provides a single place for others to reference when trying to understand why the software operates the way it does or why certain changes were made.
Setuptools makes extensive use of hyperlinks to tickets in the changelog so that system integrators and other users can get a quick summary, but then jump to the in-depth discussion about any subject referenced.
Grab the code at Bitbucket:
$ hg clone https://bitbucket.org/pypa/setuptools
If you want to contribute changes, we recommend you fork the repository on Bitbucket, commit the changes to your repository, and then make a pull request on Bitbucket. If you make some changes, don’t forget to:
Please commit all changes in the ‘default’ branch against the latest available commit or for bug-fixes, against an earlier commit or release in which the bug occurred.
If you find yourself working on more than one issue at a time, Setuptools generally prefers Git-style branches, so use Mercurial bookmarks or Git branches or multiple forks to maintain separate efforts.
Setuptools also maintains an unofficial Git mirror in Github. Contributors are welcome to submit pull requests here, but because they are not integrated with the Bitbucket Issue tracker, linking pull requests to tickets is more difficult. The Continuous Integration tests that validate every release are run from this mirror.
The primary tests are run using py.test. To run the tests:
$ python setup.py ptr
Or install py.test into your environment and run py.test.
Under continuous integration, additional tests may be run. See the .travis.yml file for full details on the tests run under Travis-CI.
Setuptools follows semver with some exceptions:
