Release Process and Rules
=========================
.. versionadded:: v2.6.2
Starting with the version to be released after ``v2.6.2``, the following rules
will govern and describe how the Requests core team produces a new release.
Major Releases
--------------
A major release will include breaking changes. When it is versioned, it will
be versioned as ``vX.0.0``. For example, if the previous release was
``v10.2.7`` the next version will be ``v11.0.0``.
Breaking changes are changes that break backwards compatibility with prior
versions. If the project were to change the ``text`` attribute on a
``Response`` object to a method, that would only happen in a Major release.
Major releases may also include miscellaneous bug fixes and upgrades to
vendored packages. The core developers of Requests are committed to providing
a good user experience. This means we're also committed to preserving
backwards compatibility as much as possible. Major releases will be infrequent
and will need strong justifications before they are considered.
Minor Releases
--------------
A minor release will not include breaking changes but may include
miscellaneous bug fixes and upgrades to vendored packages. If the previous
version of Requests released was ``v10.2.7`` a minor release would be
versioned as ``v10.3.0``.
Minor releases will be backwards compatible with releases that have the same
major version number. In other words, all versions that would start with
``v10.`` should be compatible with each other.
Hotfix Releases
---------------
A hotfix release will only include bug fixes that were missed when the project
released the previous version. If the previous version of Requests released
``v10.2.7`` the hotfix release would be versioned as ``v10.2.8``.
Hotfixes will **not** include upgrades to vendored dependences after
``v2.6.2``
Reasoning
---------
In the 2.5 and 2.6 release series, the Requests core team upgraded vendored
dependencies and caused a great deal of headaches for both users and the core
team. To reduce this pain, we're forming a concrete set of procedures so
expectations will be properly set.

.. _contributing:
Contributor's Guide
===================
If you're reading this you're probably interested in contributing to
Requests. First, We'd like to say: thank you! Open source projects
live-and-die based on the support they receive from others, and the fact that
you're even considering supporting Requests is very generous of
you.
This document lays out guidelines and advice for contributing to Requests.
If you're thinking of contributing, start by reading this thoroughly and
getting a feel for how contributing to the project works. If you have any
questions, feel free to reach out to either `Ian Cordasco`_ or `Cory Benfield`_,
the primary maintainers.
The guide is split into sections based on the type of contribution you're
thinking of making, with a section that covers general guidelines for all
contributors.
.. _Ian Cordasco: http://www.coglib.com/~icordasc/
.. _Cory Benfield: https://lukasa.co.uk/about
All Contributions
-----------------
Be Cordial
~~~~~~~~~~
**Be cordial or be on your way.**
Requests has one very important rule governing all forms of contribution,
including reporting bugs or requesting features. This golden rule is
`be cordial or be on your way`_. **All contributions are welcome**, as long as
everyone involved is treated with respect.
.. _be cordial or be on your way: http://kennethreitz.org/be-cordial-or-be-on-your-way/
.. _early-feedback:
Get Early Feedback
~~~~~~~~~~~~~~~~~~
If you are contributing, do not feel the need to sit on your contribution until
it is perfectly polished and complete. It helps everyone involved for you to
seek feedback as early as you possibly can. Submitting an early, unfinished
version of your contribution for feedback in no way prejudices your chances of
getting that contribution accepted, and can save you from putting a lot of work
into a contribution that is not suitable for the project.
Contribution Suitability
~~~~~~~~~~~~~~~~~~~~~~~~
The project maintainer has the last word on whether or not a contribution is
suitable for Requests. All contributions will be considered, but from time
to time contributions will be rejected because they do not suit the project.
If your contribution is rejected, don't despair! So long as you followed these
guidelines, you'll have a much better chance of getting your next contribution
accepted.
Code Contributions
------------------
Steps
~~~~~
When contributing code, you'll want to follow this checklist:
1. Fork the repository on GitHub.
2. Run the tests to confirm they all pass on your system. If they don't, you'll
need to investigate why they fail. If you're unable to diagnose this
yourself, raise it as a bug report by following the guidelines in this
document: :ref:`bug-reports`.
3. Write tests that demonstrate your bug or feature. Ensure that they fail.
4. Make your change.
5. Run the entire test suite again, confirming that all tests pass *including
the ones you just added*.
6. Send a GitHub Pull Request to the main repository's ``master`` branch.
GitHub Pull Requests are the expected method of code collaboration on this
project.
The following sub-sections go into more detail on some of the points above.
Code Review
~~~~~~~~~~~
Contributions will not be merged until they've been code reviewed. You should
implement any code review feedback unless you strongly object to it. In the
event that you object to the code review feedback, you should make your case
clearly and calmly. If, after doing so, the feedback is judged to still apply,
you must either apply the feedback or withdraw your contribution.
New Contributors
~~~~~~~~~~~~~~~~
If you are new or relatively new to Open Source, welcome! Requests aims to
be a gentle introduction to the world of Open Source. If you're concerned about
how best to contribute, please consider mailing a maintainer (listed above) and
asking for help.
Please also check the :ref:`early-feedback` section.
Documentation Contributions
---------------------------
Documentation improvements are always welcome! The documentation files live in
the ``docs/`` directory of the codebase. They're written in
`reStructuredText`_, and use `Sphinx`_ to generate the full suite of
documentation.
When contributing documentation, please attempt to follow the style of the
documentation files. This means a soft-limit of 79 characters wide in your text
files and a semi-formal prose style.
.. _reStructuredText: http://docutils.sourceforge.net/rst.html
.. _Sphinx: http://sphinx-doc.org/index.html
.. _bug-reports:
Bug Reports
-----------
Bug reports are hugely important! Before you raise one, though, please check
through the `GitHub issues`_, **both open and closed**, to confirm that the bug
hasn't been reported before. Duplicate bug reports are a huge drain on the time
of other contributors, and should be avoided as much as possible.
.. _GitHub issues: https://github.com/kennethreitz/requests/issues
Feature Requests
----------------
Requests is in a perpeptual feature freeze. The maintainers believe that
requests contains every major feature currently required by the vast majority
of users.
If you believe there is a feature missing, feel free to raise a feature
request, but please do be aware that the overwhelming likelihood is that your
feature request will not be accepted.
