Contributing to Django
|
|
======================
|
|
|
|
If you think working *with* Django is fun, wait until you start working *on* it.
|
|
We're passionate about helping Django users make the jump to contributing members
|
|
of the community, so there are many ways you can help Django's development:
|
|
|
|
* Blog about Django. We syndicate all the Django blogs we know about on
|
|
the `community page`_; contact jacob@jacobian.org if you've got a blog
|
|
you'd like to see on that page.
|
|
|
|
* Report bugs and request features in our `ticket tracker`_. Please read
|
|
`Reporting bugs`_, below, for the details on how we like our bug reports
|
|
served up.
|
|
|
|
* Submit patches for new and/or fixed behavior. Please read `Submitting
|
|
patches`_, below, for details on how to submit a patch.
|
|
|
|
* Join the `django-developers`_ mailing list and share your ideas for how
|
|
to improve Django. We're always open to suggestions, although we're
|
|
likely to be skeptical of large-scale suggestions without some code to
|
|
back it up.
|
|
|
|
* Triage patches that have been submitted by other users. Please read
|
|
`Ticket triage`_ below, for details on the triage process.
|
|
|
|
That's all you need to know if you'd like to join the Django development
|
|
community. The rest of this document describes the details of how our community
|
|
works and how it handles bugs, mailing lists, and all the other minutiae of
|
|
Django development.
|
|
|
|
Reporting bugs
|
|
==============
|
|
|
|
Well-written bug reports are *incredibly* helpful. However, there's a certain
|
|
amount of overhead involved in working with any bug tracking system, so your
|
|
help in keeping our ticket tracker as useful as possible is appreciated. In
|
|
particular:
|
|
|
|
* **Do** read the FAQ_ to see if your issue might be a well-known question.
|
|
|
|
* **Do** `search the tracker`_ to see if your issue has already been filed.
|
|
|
|
* **Do** ask on `django-users`_ *first* if you're not sure if what you're
|
|
seeing is a bug.
|
|
|
|
* **Do** write complete, reproducible, specific bug reports. Include as
|
|
much information as you possibly can, complete with code snippets, test
|
|
cases, etc. This means including a clear, concise description of the
|
|
problem, and a clear set of instructions for replicating the problem.
|
|
A minimal example that illustrates the bug in a nice small test case
|
|
is the best possible bug report.
|
|
|
|
* **Don't** use the ticket system to ask support questions. Use the
|
|
`django-users`_ list, or the `#django`_ IRC channel for that.
|
|
|
|
* **Don't** use the ticket system to make large-scale feature requests.
|
|
We like to discuss any big changes to Django's core on the `django-developers`_
|
|
list before actually working on them.
|
|
|
|
* **Don't** reopen issues that have been marked "wontfix". This mark means
|
|
that the decision has been made that we can't or won't fix this particular
|
|
issue. If you're not sure why, please ask on `django-developers`_.
|
|
|
|
* **Don't** use the ticket tracker for lengthy discussions, because they're
|
|
likely to get lost. If a particular ticket is controversial, please move
|
|
discussion to `django-developers`_.
|
|
|
|
* **Don't** post to django-developers just to announce that you have filed
|
|
a bug report. All the tickets are mailed to another list
|
|
(`django-updates`_), which is tracked by developers and triagers, so we
|
|
see them as they are filed.
|
|
|
|
.. _django-updates: http://groups.google.com/group/django-updates
|
|
|
|
Reporting security issues
|
|
=========================
|
|
|
|
Report security issues to security@djangoproject.com. This is a private list
|
|
only open to long-time, highly trusted Django developers, and its archives are
|
|
not publicly readable.
|
|
|
|
In the event of a confirmed vulnerability in Django itself, we will take the
|
|
following actions:
|
|
|
|
* Acknowledge to the reporter that we've received the report and that a fix
|
|
is forthcoming. We'll give a rough timeline and ask the reporter to keep
|
|
the issue confidential until we announce it.
|
|
|
|
* Halt all other development as long as is needed to develop a fix, including
|
|
patches against the current and two previous releases.
|
|
|
|
* Determine a go-public date for announcing the vulnerability and the fix.
|
|
To try to mitigate a possible "arms race" between those applying the patch
|
|
and those trying to exploit the hole, we will not announce security
|
|
problems immediately.
|
|
|
|
* Pre-notify everyone we know to be running the affected version(s) of
|
|
Django. We will send these notifications through private e-mail which will
|
|
include documentation of the vulnerability, links to the relevant patch(es),
|
|
and a request to keep the vulnerability confidential until the official
|
|
go-public date.
|
|
|
|
* Publicly announce the vulnerability and the fix on the pre-determined
|
|
go-public date. This will probably mean a new release of Django, but
|
|
in some cases it may simply be patches against current releases.
|
|
|
|
Submitting patches
|
|
==================
|
|
|
|
We're always grateful for patches to Django's code. Indeed, bug reports with
|
|
associated patches will get fixed *far* more quickly than those without patches.
|
|
|
|
"Claiming" tickets
|
|
------------------
|
|
|
|
In an open-source project with hundreds of contributors around the world, it's
|
|
important to manage communication efficiently so that work doesn't get
|
|
duplicated and contributors can be as effective as possible. Hence, our policy
|
|
is for contributors to "claim" tickets in order to let other developers know
|
|
that a particular bug or feature is being worked on.
|
|
|
|
If you have identified a contribution you want to make and you're capable of
|
|
fixing it (as measured by your coding ability, knowledge of Django internals
|
|
and time availability), claim it by following these steps:
|
|
|
|
* `Create an account`_ to use in our ticket system.
|
|
* If a ticket for this issue doesn't exist yet, create one in our
|
|
`ticket tracker`_.
|
|
* If a ticket for this issue already exists, make sure nobody else has
|
|
claimed it. To do this, look at the "Assigned to" section of the ticket.
|
|
If it's assigned to "nobody," then it's available to be claimed.
|
|
Otherwise, somebody else is working on this ticket, and you either find
|
|
another bug/feature to work on, or contact the developer working on the
|
|
ticket to offer your help.
|
|
* Log into your account, if you haven't already, by clicking "Login" in the
|
|
upper right of the ticket page.
|
|
* Claim the ticket by clicking the radio button next to "Accept ticket"
|
|
near the bottom of the page, then clicking "Submit changes."
|
|
|
|
.. _Create an account: http://www.djangoproject.com/accounts/register/
|
|
|
|
Ticket claimers' responsibility
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Once you've claimed a ticket, you have a responsibility to work on that ticket
|
|
in a reasonably timely fashion. If you don't have time to work on it, either
|
|
unclaim it or don't claim it in the first place!
|
|
|
|
Core Django developers go through the list of claimed tickets from time to
|
|
time, checking whether any progress has been made. If there's no sign of
|
|
progress on a particular claimed ticket for a week or two after it's been
|
|
claimed, we will unclaim it for you so that it's no longer monopolized and
|
|
somebody else can claim it.
|
|
|
|
If you've claimed a ticket and it's taking a long time (days or weeks) to code,
|
|
keep everybody updated by posting comments on the ticket. That way, we'll know
|
|
not to unclaim it. More communication is better than less communication!
|
|
|
|
Which tickets should be claimed?
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Of course, going through the steps of claiming tickets is overkill in some
|
|
cases. In the case of small changes, such as typos in the documentation or
|
|
small bugs that will only take a few minutes to fix, you don't need to jump
|
|
through the hoops of claiming tickets. Just submit your patch and be done with
|
|
it.
|
|
|
|
Patch style
|
|
-----------
|
|
|
|
* Make sure your code matches our `coding style`_.
|
|
|
|
* Submit patches in the format returned by the ``svn diff`` command.
|
|
An exception is for code changes that are described more clearly in plain
|
|
English than in code. Indentation is the most common example; it's hard to
|
|
read patches when the only difference in code is that it's indented.
|
|
|
|
* When creating patches, always run ``svn diff`` from the top-level
|
|
``trunk`` directory -- i.e., the one that contains ``django``, ``docs``,
|
|
``tests``, ``AUTHORS``, etc. This makes it easy for other people to apply
|
|
your patches.
|
|
|
|
* Attach patches to a ticket in the `ticket tracker`_, using the "attach file"
|
|
button. Please *don't* put the patch in the ticket description or comment
|
|
unless it's a single line patch.
|
|
|
|
* Name the patch file with a ``.diff`` extension; this will let the ticket
|
|
tracker apply correct syntax highlighting, which is quite helpful.
|
|
|
|
* Check the "Has patch" box on the ticket details. This will make it
|
|
obvious that the ticket includes a patch, and it will add the ticket to
|
|
the `list of tickets with patches`_.
|
|
|
|
* The code required to fix a problem or add a feature is an essential part
|
|
of a patch, but it is not the only part. A good patch should also include
|
|
a regression test to validate the behavior that has been fixed (and prevent
|
|
the problem from arising again).
|
|
|
|
* If the code associated with a patch adds a new feature, or modifies behavior
|
|
of an existing feature, the patch should also contain documentation.
|
|
|
|
Non-trivial patches
|
|
-------------------
|
|
|
|
A "non-trivial" patch is one that is more than a simple bug fix. It's a patch
|
|
that introduces Django functionality and makes some sort of design decision.
|
|
|
|
If you provide a non-trivial patch, include evidence that alternatives have
|
|
been discussed on `django-developers`_. If you're not sure whether your patch
|
|
should be considered non-trivial, just ask.
|
|
|
|
Ticket triage
|
|
=============
|
|
|
|
Unfortunately, not all bug reports in the `ticket tracker`_ provide all
|
|
the `required details`_. A number of tickets have patches, but those patches
|
|
don't meet all the requirements of a `good patch`_.
|
|
|
|
One way to help out is to *triage* bugs that have been reported by other
|
|
users. A couple of dedicated volunteers work on this regularly, but more help
|
|
is always appreciated.
|
|
|
|
Most of the workflow is based around the concept of a ticket's "triage stage".
|
|
This stage describes where in its lifetime a given ticket is at any time.
|
|
Along with a handful of flags, this field easily tells us what and who each
|
|
ticket is waiting on.
|
|
|
|
Since a picture is worth a thousand words, let's start there:
|
|
|
|
.. image:: http://media.djangoproject.com/img/doc/djangotickets.png
|
|
:height: 451
|
|
:width: 590
|
|
:alt: Django's ticket workflow
|
|
|
|
We've got two roles here:
|
|
|
|
* Core developers: people with commit access who make the decisions and
|
|
write the bulk of the code.
|
|
|
|
* Ticket triagers: community members who keep track of tickets, making
|
|
sure the tickets are always categorized correctly.
|
|
|
|
Second, note the four triage stages:
|
|
|
|
1. A ticket starts as "Unreviewed", meaning that a triager has yet to
|
|
examine the ticket and move it along.
|
|
|
|
2. "Design decision needed" means "this concept requires a design
|
|
decision," which should be discussed either in the ticket comments or on
|
|
django-developers.
|
|
|
|
3. Once a ticket is ruled to be approved for fixing, it's moved into the
|
|
"Accepted" stage. This stage is where all the real work gets done.
|
|
|
|
4. If a ticket has an associated patch (see below), a triager will review the
|
|
patch. If the patch is complete, it'll be marked as "ready for checkin" so
|
|
that a core developer knows to review and check in the patches.
|
|
|
|
The second part of this workflow involves a set of flags the describe what the
|
|
ticket has or needs in order to be "ready for checkin":
|
|
|
|
"Has patch"
|
|
This means the ticket has an associated patch_. These will be
|
|
reviewed to see if the patch is "good".
|
|
|
|
"Needs documentation"
|
|
This flag is used for tickets with patches that need associated
|
|
documentation. Complete documentation of features is a prerequisite
|
|
before we can check a fix into the codebase.
|
|
|
|
"Needs tests"
|
|
This flags the patch as needing associated unit tests. Again, this is a
|
|
required part of a valid patch.
|
|
|
|
"Patch needs improvement"
|
|
This flag means that although the ticket *has* a patch, it's not quite
|
|
ready for checkin. This could mean the patch no longer applies
|
|
cleanly, or that the code doesn't live up to our standards.
|
|
|
|
A ticket can be resolved in a number of ways:
|
|
|
|
"fixed"
|
|
Used by one of the core developers once a patch has been rolled into
|
|
Django and the issue is fixed.
|
|
|
|
"invalid"
|
|
Used if the ticket is found to be incorrect or a user error.
|
|
|
|
"wontfix"
|
|
Used when a core developer decides that this request is not
|
|
appropriate for consideration in Django. This is usually chosen after
|
|
discussion in the ``django-developers`` mailing list, and you should
|
|
feel free to join in when it's something you care about.
|
|
|
|
"duplicate"
|
|
Used when another ticket covers the same issue. By closing duplicate
|
|
tickets, we keep all the discussion in one place, which helps everyone.
|
|
|
|
"worksforme"
|
|
Used when the triage team is unable to replicate the original bug.
|
|
|
|
If you believe that the ticket was closed in error -- because you're
|
|
still having the issue, or it's popped up somewhere else, or the triagers have
|
|
-- made a mistake, please reopen the ticket and tell us why. Please do not
|
|
reopen tickets that have been marked as "wontfix" by core developers.

|
Submitting and maintaining translations
|
|
=======================================
|
|
|
|
Various parts of Django, such as the admin site and validator error messages,
|
|
are internationalized. This means they display different text depending on a
|
|
user's language setting.
|
|
|
|
These translations are contributed by Django users worldwide. If you find an
|
|
incorrect translation, or if you'd like to add a language that isn't yet
|
|
translated, here's what to do:
|
|
|
|
* Join the `Django i18n mailing list`_ and introduce yourself.
|
|
* Create and submit translations using the methods described in the
|
|
`i18n documentation`_.
|
|
|
|
.. _Django i18n mailing list: http://groups.google.com/group/django-i18n/
|
|
.. _i18n documentation: ../i18n/
|
|
|
|
Coding style
|
|
============
|
|
|
|
Please follow these coding standards when writing code for inclusion in Django:
|
|
|
|
* Unless otherwise specified, follow `PEP 8`_.
|
|
|
|
* Use four spaces for indentation.
|
|
|
|
* Use underscores, not camelCase, for variable, function and method names
|
|
(i.e. ``poll.get_unique_voters()``, not ``poll.getUniqueVoters``).
|
|
|
|
* Use ``InitialCaps`` for class names (or for factory functions that
|
|
return classes).
|
|
|
|
* Mark all strings for internationalization; see the `i18n documentation`_
|
|
for details.
|
|
|
|
* In docstrings, use "action words" such as::
|
|
|
|
def foo():
|
|
"""
|
|
Calculates something and returns the result.
|
|
"""
|
|
pass
|
|
|
|
Here's an example of what not to do::
|
|
|
|
def foo():
|
|
"""
|
|
Calculate something and return the result.
|
|
"""
|
|
pass
|
|
|
|
* Please don't put your name in the code you contribute. Our policy is to
|
|
keep contributors' names in the ``AUTHORS`` file distributed with Django
|
|
-- not scattered throughout the codebase itself. Feel free to include a
|
|
change to the ``AUTHORS`` file in your patch if you make more than a
|
|
single trivial change.
|
|
|
|
Template style
|
|
--------------
|
|
|
|
* In Django template code, put one (and only one) space between the curly
|
|
brackets and the tag contents.
|
|
|
|
Do this::
|
|
|
|
{{ foo }}
|
|
|
|
Don't do this::
|
|
|
|
{{foo}}
|
|
|
|
View style
|
|
----------
|
|
|
|
* In Django views, the first parameter in a view function should be called
|
|
``request``.
|
|
|
|
Do this::
|
|
|
|
def my_view(request, foo):
|
|
# ...
|
|
|
|
Don't do this::
|
|
|
|
def my_view(req, foo):
|
|
# ...
|
|
|
|
Model style
|
|
-----------
|
|
|
|
* Field names should be all lowercase, using underscores instead of
|
|
camelCase.
|
|
|
|
Do this::
|
|
|
|
class Person(models.Model):
|
|
first_name = models.CharField(max_length=20)
|
|
last_name = models.CharField(max_length=40)
|
|
|
|
Don't do this::
|
|
|
|
class Person(models.Model):
|
|
FirstName = models.CharField(max_length=20)
|
|
Last_Name = models.CharField(max_length=40)
|
|
|
|
* The ``class Meta`` should appear *after* the fields are defined, with
|
|
a single blank line separating the fields and the class definition.
|
|
|
|
Do this::
|
|
|
|
class Person(models.Model):
|
|
first_name = models.CharField(max_length=20)
|
|
last_name = models.CharField(max_length=40)
|
|
|
|
class Meta:
|
|
verbose_name_plural = 'people'
|
|
|
|
Don't do this::
|
|
|
|
class Person(models.Model):
|
|
first_name = models.CharField(max_length=20)
|
|
last_name = models.CharField(max_length=40)
|
|
class Meta:
|
|
verbose_name_plural = 'people'
|
|
|
|
Don't do this, either::
|
|
|
|
class Person(models.Model):
|
|
class Meta:
|
|
verbose_name_plural = 'people'
|
|
|
|
first_name = models.CharField(max_length=20)
|
|
last_name = models.CharField(max_length=40)
|
|
|
|
* The order of model inner classes and standard methods should be as
|
|
follows (noting that these are not all required):
|
|
|
|
* All database fields
|
|
* ``class Meta``
|
|
* ``class Admin``
|
|
* ``def __unicode__()``
|
|
* ``def __str__()``
|
|
* ``def save()``
|
|
* ``def get_absolute_url()``
|
|
* Any custom methods
|
|
|
|
* If ``choices`` is defined for a given model field, define the choices as
|
|
a tuple of tuples, with an all-uppercase name, either near the top of the
|
|
model module or just above the model class. Example::
|
|
|
|
GENDER_CHOICES = (
|
|
('M', 'Male'),
|
|
('F', 'Female'),
|
|
)
|
|
|
|
Documentation style
|
|
===================
|
|
|
|
We place a high importance on consistency and readability of documentation.
|
|
(After all, Django was created in a journalism environment!)
|
|
|
|
How to document new features
|
|
----------------------------
|
|
|
|
We treat our documentation like we treat our code: we aim to improve it as
|
|
often as possible. This section explains how writers can craft their
|
|
documentation changes in the most useful and least error-prone ways.
|
|
|
|
Documentation changes come in two forms:
|
|
|
|
* General improvements -- Typo corrections, error fixes and better
|
|
explanations through clearer writing and more examples.
|
|
|
|
* New features -- Documentation of features that have been added to the
|
|
framework since the last release.
|
|
|
|
Our philosophy is that "general improvements" are something that *all* current
|
|
Django users should benefit from, including users of trunk *and* users of the
|
|
latest release. Hence, the documentation section on djangoproject.com points
|
|
people by default to the newest versions of the docs, because they have the
|
|
latest and greatest content. (In fact, the Web site pulls directly from the
|
|
Subversion repository, converting to HTML on the fly.)
|
|
|
|
But this decision to feature bleeding-edge documentation has one large caveat:
|
|
any documentation of *new* features will be seen by Django users who don't
|
|
necessarily have access to those features yet, because they're only using the
|
|
latest release. Thus, our policy is:
|
|
|
|
**All documentation of new features should be written in a way that clearly
|
|
designates the features are only available in the Django development
|
|
version. Assume documentation readers are using the latest release, not the
|
|
development version.**
|
|
|
|
Our traditional way of marking new features is by prefacing the features'
|
|
documentation with: "New in Django development version." Changes aren't
|
|
*required* to include this exact text, but all documentation of new features
|
|
should include the phrase "development version," so we can find and remove
|
|
those phrases for the next release.
|
|
|
|
Guidelines for ReST files
|
|
-------------------------
|
|
|
|
These guidelines regulate the format of our ReST documentation:
|
|
|
|
* In section titles, capitalize only initial words and proper nouns.
|
|
|
|
* Wrap the documentation at 80 characters wide, unless a code example
|
|
is significantly less readable when split over two lines, or for another
|
|
good reason.
|
|
|
|
Commonly used terms
|
|
-------------------
|
|
|
|
Here are some style guidelines on commonly used terms throughout the
|
|
documentation:
|
|
|
|
* **Django** -- when referring to the framework, capitalize Django. It is
|
|
lowercase only in Python code and in the djangoproject.com logo.
|
|
|
|
* **e-mail** -- it has a hyphen.
|
|
|
|
* **MySQL**
|
|
|
|
* **PostgreSQL**
|
|
|
|
* **Python** -- when referring to the language, capitalize Python.
|
|
|
|
* **realize**, **customize**, **initialize**, etc. -- use the American
|
|
"ize" suffix, not "ise."
|
|
|
|
* **SQLite**
|
|
|
|
* **subclass** -- it's a single word without a hyphen, both as a verb
|
|
("subclass that model") and as a noun ("create a subclass").
|
|
|
|
* **Web**, **World Wide Web**, **the Web** -- note Web is always
|
|
capitalized when referring to the World Wide Web.
|
|
|
|
* **Web site** -- use two words, with Web capitalized.
|
|
|
|
Django-specific terminology
|
|
---------------------------
|
|
|
|
* **model** -- it's not capitalized.
|
|
|
|
* **template** -- it's not capitalized.
|
|
|
|
* **URLconf** -- use three capitalized letters, with no space before
|
|
"conf."
|
|
|
|
* **view** -- it's not capitalized.
|
|
|
|
Committing code
|
|
===============
|
|
|
|
Please follow these guidelines when committing code to Django's Subversion
|
|
repository:
|
|
|
|
* For any medium-to-big changes, where "medium-to-big" is according to your
|
|
judgment, please bring things up on the `django-developers`_ mailing list
|
|
before making the change.
|
|
|
|
If you bring something up on `django-developers`_ and nobody responds,
|
|
please don't take that to mean your idea is great and should be
|
|
implemented immediately because nobody contested it. Django's lead
|
|
developers don't have a lot of time to read mailing-list discussions
|
|
immediately, so you may have to wait a couple of days before getting a
|
|
response.
|
|
|
|
* Write detailed commit messages in the past tense, not present tense.
|
|
|
|
* Good: "Fixed Unicode bug in RSS API."
|
|
* Bad: "Fixes Unicode bug in RSS API."
|
|
* Bad: "Fixing Unicode bug in RSS API."
|
|
|
|
* For commits to a branch, prefix the commit message with the branch name.
|
|
For example: "magic-removal: Added support for mind reading."
|
|
|
|
* Limit commits to the most granular change that makes sense. This means,
|
|
use frequent small commits rather than infrequent large commits. For
|
|
example, if implementing feature X requires a small change to library Y,
|
|
first commit the change to library Y, then commit feature X in a separate
|
|
commit. This goes a *long way* in helping all core Django developers
|
|
follow your changes.
|
|
|
|
* If your commit closes a ticket in the Django `ticket tracker`_, begin
|
|
your commit message with the text "Fixed #abc", where "abc" is the number
|
|
of the ticket your commit fixes. Example: "Fixed #123 -- Added support
|
|
for foo". We've rigged Subversion and Trac so that any commit message
|
|
in that format will automatically close the referenced ticket and post a
|
|
comment to it with the full commit message.
|
|
|
|
If your commit closes a ticket and is in a branch, use the branch name
|
|
first, then the "Fixed #abc." For example:
|
|
"magic-removal: Fixed #123 -- Added whizbang feature."
|
|
|
|
For the curious: We're using a `Trac post-commit hook`_ for this.
|
|
|
|
.. _Trac post-commit hook: http://trac.edgewall.org/browser/trunk/contrib/trac-post-commit-hook
|
|
|
|
* If your commit references a ticket in the Django `ticket tracker`_ but
|
|
does *not* close the ticket, include the phrase "Refs #abc", where "abc"
|
|
is the number of the ticket your commit references. We've rigged
|
|
Subversion and Trac so that any commit message in that format will
|
|
automatically post a comment to the appropriate ticket.
|
|
|
|
Unit tests
|
|
==========
|
|
|
|
Django comes with a test suite of its own, in the ``tests`` directory of the
|
|
Django tarball. It's our policy to make sure all tests pass at all times.
|
|
|
|
The tests cover:
|
|
|
|
* Models and the database API (``tests/modeltests/``).
|
|
* The cache system (``tests/regressiontests/cache.py``).
|
|
* The ``django.utils.dateformat`` module (``tests/regressiontests/dateformat/``).
|
|
* Database typecasts (``tests/regressiontests/db_typecasts/``).
|
|
* The template system (``tests/regressiontests/templates/`` and
|
|
``tests/regressiontests/defaultfilters/``).
|
|
* ``QueryDict`` objects (``tests/regressiontests/httpwrappers/``).
|
|
* Markup template tags (``tests/regressiontests/markup/``).
|
|
|
|
We appreciate any and all contributions to the test suite!
|
|
|
|
The Django tests all use the testing infrastructure that ships with Django for
|
|
testing applications. See `Testing Django applications`_ for an explanation of
|
|
how to write new tests.
|
|
|
|
.. _Testing Django applications: ../testing/
|
|
|
|
Running the unit tests
|
|
----------------------
|
|
|
|
To run the tests, ``cd`` to the ``tests/`` directory and type::
|
|
|
|
./runtests.py --settings=path.to.django.settings
|
|
|
|
Yes, the unit tests need a settings module, but only for database connection
|
|
info, with the ``DATABASE_ENGINE`` setting. You will also need a ``ROOT_URLCONF``
|
|
setting (its value is ignored; it just needs to be present) and a ``SITE_ID``
|
|
setting (any non-zero integer value will do) in order for all the tests to pass.
|
|
|
|
The unit tests will not touch your existing databases; they create a new
|
|
database, called ``django_test_db``, which is deleted when the tests are
|
|
finished. This means your user account needs permission to execute ``CREATE
|
|
DATABASE``.
|
|
|
|
Requesting features
|
|
===================
|
|
|
|
We're always trying to make Django better, and your feature requests are a key
|
|
part of that. Here are some tips on how to most effectively make a request:
|
|
|
|
* Request the feature on `django-developers`_, not in the ticket tracker;
|
|
it'll get read more closely if it's on the mailing list.
|
|
|
|
* Describe clearly and concisely what the missing feature is and how you'd
|
|
like to see it implemented. Include example code (non-functional is OK)
|
|
if possible.
|
|
|
|
* Explain *why* you'd like the feature. In some cases this is obvious, but
|
|
since Django is designed to help real developers get real work done,
|
|
you'll need to explain it, if it isn't obvious why the feature would be
|
|
useful.
|
|
|
|
As with most open-source projects, code talks. If you are willing to write the
|
|
code for the feature yourself or if (even better) you've already written it,
|
|
it's much more likely to be accepted. If it's a large feature that might need
|
|
multiple developers we're always happy to give you an experimental branch in
|
|
our repository; see below.
|
|
|
|
Branch policy
|
|
=============
|
|
|
|
In general, most development is confined to the trunk, and the trunk
|
|
is kept stable. People should be able to run production sites against the
|
|
trunk at any time.
|
|
|
|
Thus, large architectural changes -- that is, changes too large to be
|
|
encapsulated in a single patch, or changes that need multiple eyes on them --
|
|
will have dedicated branches. See, for example, the `i18n branch`_. If you
|
|
have a change of this nature that you'd like to work on, ask on
|
|
`django-developers`_ for a branch to be created for you. We'll create a branch
|
|
for pretty much any kind of experimenting you'd like to do.
|
|
|
|
We will only branch entire copies of the Django tree, even if work is only
|
|
happening on part of that tree. This makes it painless to switch to a branch.
|
|
|
|
Developers working on a branch should periodically merge changes from the trunk
|
|
into the branch. Please merge at least once a week. Every time you merge from
|
|
the trunk, note the merge and revision numbers in the commit message.
|
|
|
|
Once the branch is stable and ready to be merged into the trunk, alert
|
|
`django-developers`_.
|
|
|
|
After a branch has been merged, it should be considered "dead"; write access to
|
|
it will be disabled, and old branches will be periodically "trimmed." To keep
|
|
our SVN wrangling to a minimum, we won't be merging from a given branch into the
|
|
trunk more than once.
|
|
|
|
Using branches
|
|
--------------
|
|
|
|
To use a branch, you'll need to do two things:
|
|
|
|
* Get the branch's code through Subversion.
|
|
|
|
* Point your Python ``site-packages`` directory at the branch's version of
|
|
the ``django`` package rather than the version you already have
|
|
installed.
|
|
|
|
Getting the code from Subversion
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
To get the latest version of a branch's code, check it out using Subversion::
|
|
|
|
svn co http://code.djangoproject.com/svn/django/branches/<branch>/
|
|
|
|
...where ``<branch>`` is the branch's name. See the `list of branch names`_.
|
|
|
|
Alternatively, you can automatically convert an existing directory of the
|
|
Django source code as long as you've checked it out via Subversion. To do the
|
|
conversion, execute this command from within your ``django`` directory::
|
|
|
|
svn switch http://code.djangoproject.com/svn/django/branches/<branch>/
|
|
|
|
The advantage of using ``svn switch`` instead of ``svn co`` is that the
|
|
``switch`` command retains any changes you might have made to your local copy
|
|
of the code. It attempts to merge those changes into the "switched" code. The
|
|
disadvantage is that it may cause conflicts with your local changes if the
|
|
"switched" code has altered the same lines of code.
|
|
|
|
(Note that if you use ``svn switch``, you don't need to point Python at the new
|
|
version, as explained in the next section.)
|
|
|
|
.. _list of branch names: http://code.djangoproject.com/browser/django/branches
|
|
|
|
Pointing Python at the new Django version
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Once you've retrieved the branch's code, you'll need to change your Python
|
|
``site-packages`` directory so that it points to the branch version of the
|
|
``django`` directory. (The ``site-packages`` directory is somewhere such as
|
|
``/usr/lib/python2.4/site-packages`` or
|
|
``/usr/local/lib/python2.4/site-packages`` or ``C:\Python\site-packages``.)
|
|
|
|
The simplest way to do this is by renaming the old ``django`` directory to
|
|
``django.OLD`` and moving the trunk version of the code into the directory
|
|
and calling it ``django``.
|
|
|
|
Alternatively, you can use a symlink called ``django`` that points to the
|
|
location of the branch's ``django`` package. If you want to switch back, just
|
|
change the symlink to point to the old code.
|
|
|
|
A third option is to use a `path file`_ (``<something>.pth``) which should
|
|
work on all systems (including Windows, which doesn't have symlinks
|
|
available). First, make sure there are no files, directories or symlinks named
|
|
``django`` in your ``site-packages`` directory. Then create a text file named
|
|
``django.pth`` and save it to your ``site-packages`` directory. That file
|
|
should contain a path to your copy of Django on a single line and optional
|
|
comments. Here is an example that points to multiple branches. Just uncomment
|
|
the line for the branch you want to use ('Trunk' in this example) and make
|
|
sure all other lines are commented::
|
|
|
|
# Trunk is a svn checkout of:
|
|
# http://code.djangoproject.com/svn/django/trunk/
|
|
#
|
|
/path/to/trunk
|
|
|
|
# <branch> is a svn checkout of:
|
|
# http://code.djangoproject.com/svn/django/branches/<branch>/
|
|
#
|
|
#/path/to/<branch>
|
|
|
|
# On windows a path may look like this:
|
|
# C:/path/to/<branch>
|
|
|
|
If you're using Django 0.95 or earlier and installed it using
|
|
``python setup.py install``, you'll have a directory called something like
|
|
``Django-0.95-py2.4.egg`` instead of ``django``. In this case, edit the file
|
|
``setuptools.pth`` and remove the line that references the Django ``.egg``
|
|
file. Then copy the branch's version of the ``django`` directory into
|
|
``site-packages``.
|
|
|
|
.. _path file: http://docs.python.org/lib/module-site.html
|
|
|
|
Official releases
|
|
=================
|
|
|
|
Django's release numbering works as follows:
|
|
|
|
* Versions are numbered in the form ``A.B`` or ``A.B.C``.
|
|
|
|
* ``A`` is the major version number, which is only incremented for major
|
|
changes to Django, and these changes are not necessarily
|
|
backwards-compatible. That is, code you wrote for Django 6.0 may break
|
|
when we release Django 7.0.
|
|
|
|
* ``B`` is the minor version number, which is incremented for large yet
|
|
backwards compatible changes. Code written for Django 6.4 will continue
|
|
to work under Django 6.5.
|
|
|
|
A minor release may deprecate certain features in previous releases. If a
|
|
feature in version ``A.B`` is deprecated, it will continue to work in
|
|
version ``A.B+1``. In version ``A.B+2``, use of the feature will raise a
|
|
``PendingDeprecationWarning`` but will continue to work. Version
|
|
``A.B+3`` will remove the feature entirely. Major point releases will
|
|
always remove deprecated features immediately.
|
|
|
|
* ``C`` is the micro version number which, is incremented for bug and
|
|
security fixes. A new micro-release will always be 100%
|
|
backwards-compatible with the previous micro-release.
|
|
|
|
* In some cases, we'll make release candidate releases. These are of the
|
|
form ``A.BrcN``, which means the ``Nth`` candidate release of version
|
|
``A.B``.
|
|
|
|
An exception to this version numbering scheme is the pre-1.0 Django code.
|
|
There's no guarantee of backwards-compatibility until the 1.0 release.
|
|
|
|
In Subversion, each Django release will be tagged under `tags/releases`_. If
|
|
it's necessary to release a bug fix release or a security release that doesn't
|
|
come from the trunk, we'll copy that tag to ``branches/releases`` to make the
|
|
bug fix release.
|
|
|
|
Deciding on features
|
|
====================
|
|
|
|
Once a feature's been requested and discussed, eventually we'll have a decision
|
|
about whether to include the feature or drop it.
|
|
|
|
Whenever possible, we strive for a rough consensus. To that end, we'll often
|
|
have informal votes on `django-developers`_ about a feature. In these votes we
|
|
follow the voting style invented by Apache and used on Python itself, where
|
|
votes are given as +1, +0, -0, or -1. Roughly translated, these votes mean:
|
|
|
|
* +1: "I love the idea and I'm strongly committed to it."
|
|
|
|
* +0: "Sounds OK to me."
|
|
|
|
* -0: "I'm not thrilled, but I won't stand in the way."
|
|
|
|
* -1: "I strongly disagree and would be very unhappy to see the idea turn
|
|
into reality."
|
|
|
|
Although these votes on django-developers are informal, they'll be taken very
|
|
seriously. After a suitable voting period, if an obvious consensus arises
|
|
we'll follow the votes.
|
|
|
|
However, consensus is not always possible. Tough decisions will be discussed by
|
|
all full committers and finally decided by the Benevolent Dictators for Life,
|
|
Adrian and Jacob.
|
|
|
|
Commit access
|
|
=============
|
|
|
|
Django has two types of committers:
|
|
|
|
Full committers
|
|
These are people who have a long history of contributions to Django's
|
|
codebase, a solid track record of being polite and helpful on the mailing
|
|
lists, and a proven desire to dedicate serious time to Django's development.
|
|
|
|
The bar is very high for full commit access. It will only be granted by
|
|
unanimous approval of all existing full committers, and the decision will err
|
|
on the side of rejection.
|
|
|
|
Partial committers
|
|
These are people who are "domain experts." They have direct check-in access
|
|
to the subsystems that fall under their jurisdiction, and they're given a
|
|
formal vote in questions that involve their subsystems. This type of access
|
|
is likely to be given to someone who contributes a large subframework to
|
|
Django and wants to continue to maintain it.
|
|
|
|
Like full committers, partial commit access is by unanimous approval of all
|
|
full committers (and any other partial committers in the same area).
|
|
However, the bar is set lower; proven expertise in the area in question is
|
|
likely to be sufficient.
|
|
|
|
To request commit access, please contact an existing committer privately. Public
|
|
requests for commit access are potential flame-war starters, and will be ignored.
