Contributing to Motor
=====================
Contributions are encouraged. Please read these guidelines before sending a
pull request.
Bugfixes and New Features
-------------------------
Before starting to write code, look for existing tickets or create one in `Jira
<https://jira.mongodb.org/browse/MOTOR>`_ for your specific issue or feature
request.
Running Tests
-------------
Install a recent version of MongoDB and run it on the default port from a clean
data directory. Pass "--setParameter enableTestCommands=1" to mongod to enable
testing MotorCursor's ``max_time_ms`` method.
Control how the tests connect to MongoDB with these environment variables:
- ``DB_IP``: Defaults to "localhost", can be a domain name or IP
- ``DB_PORT``: Defaults to 27017
- ``DB_USER``, ``DB_PASSWORD``: To test with authentication, create an admin
user and set these environment variables to the username and password
- ``CERT_DIR``: Path with alternate client.pem and ca.pem for testing.
Otherwise the suite uses those in test/certificates/.
Install `tox`_ and run it from the command line in the repository directory.
You will need a variety of Python interpreters installed. For a minimal test,
ensure you have Python 2.7 and 3.5, and run::
> tox -e tornado4-py27,tornado4-py36
The doctests pass with Python 3.6 and a MongoDB 3.6 instance running on
port 27017:
> tox -e py3-sphinx-doctest
.. _tox: https://testrun.org/tox/
General Guidelines
------------------
- Avoid backward breaking changes if at all possible.
- Write inline documentation for new classes and methods.
- Add yourself to doc/contributors.rst :)
