We use the GitHub issue tracker for reporting issues. Before opening a new issue, ensure the bug was not already reported by searching on Issue tracker first.

If you’re unable to find an open issue addressing the problem, open a new one. Be sure to include a title and clear description, as much relevant information as possible, and a code sample or an executable test case demonstrating the expected behavior that is not occurring.


When opening a pull-request, make sure that:

  • You write a comprehensive summary of your problem and the solution you implemented.
  • If you update or fix your pull-request, make sure the commits are atomic. Do not include fix-up commits in your history, rewrite it properly using e.g. git rebase –interactive and/or git commit –amend.
  • We recommend using git pull-request to send your pull-requests.

Running the Tests

Tests are run using tox. Tox creates a virtual environment for each test environment, so make sure you are using an up to date version of virtualenv.

Different test environments and configurations can be found by running the tox -l command. For example, to run tests with Python 2.7, PostgreSQL as indexer, and file as storage backend:

tox -e py27-postgresql-file

To run tests with Python 2.7, MySQL as indexer, and Ceph as storage backend:

tox -e py35-mysql-ceph
