*****************
Dealing with Bugs
*****************

Python is a mature programming language which has established a reputation for
stability.  In order to maintain this reputation, the developers would like to
know of any deficiencies you find in Python.

It can be sometimes faster to fix bugs yourself and contribute patches to
Python as it streamlines the process and involves less people. Learn how to
:ref:`contribute <contributing-to-python>`.

Documentation bugs
==================

If you find a bug in this documentation or would like to propose an improvement,
please submit a bug report on the :ref:`tracker <using-the-tracker>`.  If you
have a suggestion on how to fix it, include that as well.

If you're short on time, you can also email documentation bug reports to
docs@python.org (behavioral bugs can be sent to python-list@python.org).
'docs@' is a mailing list run by volunteers; your request will be noticed,
though it may take a while to be processed.

.. _using-the-tracker:

Using the Python issue tracker
==============================

Bug reports for Python itself should be submitted via the Python Bug Tracker
(https://bugs.python.org/).  The bug tracker offers a Web form which allows
pertinent information to be entered and submitted to the developers.

The first step in filing a report is to determine whether the problem has
already been reported.  The advantage in doing so, aside from saving the
developers time, is that you learn what has been done to fix it; it may be that
the problem has already been fixed for the next release, or additional
information is needed (in which case you are welcome to provide it if you can!).
To do this, search the bug database using the search box on the top of the page.

If the problem you're reporting is not already in the bug tracker, go back to
the Python Bug Tracker and log in.  If you don't already have a tracker account,
select the "Register" link or, if you use OpenID, one of the OpenID provider
logos in the sidebar.  It is not possible to submit a bug report anonymously.

Being now logged in, you can submit a bug.  Select the "Create New" link in the
sidebar to open the bug reporting form.

The submission form has a number of fields.  For the "Title" field, enter a
*very* short description of the problem; less than ten words is good.  In the
"Type" field, select the type of your problem; also select the "Component" and
"Versions" to which the bug relates.

In the "Comment" field, describe the problem in detail, including what you
expected to happen and what did happen.  Be sure to include whether any
extension modules were involved, and what hardware and software platform you
were using (including version information as appropriate).

Each bug report will be assigned to a developer who will determine what needs to
be done to correct the problem.  You will receive an update each time action is
taken on the bug.

.. _contributing-to-python:

Getting started contributing to Python yourself
===============================================

Beyond just reporting bugs that you find, you are also welcome to submit
patches to fix them.  You can find more information on how to get started
patching Python in the `Python Developer's Guide`_.  If you have questions,
the `core-mentorship mailing list`_ is a friendly place to get answers to
any and all questions pertaining to the process of fixing issues in Python.
