When deploying a Django application into a real production environment, you\nwill almost always want to use an official packaged release of Django.
\nHowever, if you’d like to try out in-development code from an upcoming release\nor contribute to the development of Django, you’ll need to obtain a clone of\nDjango’s source code repository.
\nThis document covers the way the code repository is laid out and how to work\nwith and find things in it.
\nThe Django source code repository uses Git to track changes to the code\nover time, so you’ll need a copy of the Git client (a program called git)\non your computer, and you’ll want to familiarize yourself with the basics of\nhow Git works.
Git’s web site offers downloads for various operating systems. The site also\ncontains vast amounts of documentation.
\nThe Django Git repository is located online at github.com/django/django. It contains the full source code for all\nDjango releases, which you can browse online.
\nThe Git repository includes several branches:
\nmaster contains the main in-development code which will become\nthe next packaged release of Django. This is where most development\nactivity is focused.
stable/A.B.x are the branches where release preparation work happens.\nThey are also used for support and bugfix releases which occur as necessary\nafter the initial release of a major or minor version.
soc20XX/<project> branches were used by students who worked on Django\nduring the 2009 and 2010 Google Summer of Code programs.
attic/<project> branches were used to develop major or experimental new\nfeatures without affecting the rest of Django’s code.
The Git repository also contains tags. These are the exact revisions from\nwhich packaged Django releases were produced, since version 1.0.
\nThe source code for the Djangoproject.com web\nsite can be found at github.com/django/djangoproject.com.
\nIf you’d like to try out the in-development code for the next release of\nDjango, or if you’d like to contribute to Django by fixing bugs or developing\nnew features, you’ll want to get the code from the master branch.
\nNote that this will get all of Django: in addition to the top-level\ndjango module containing Python code, you’ll also get a copy of Django’s\ndocumentation, test suite, packaging scripts and other miscellaneous bits.\nDjango’s code will be present in your clone as a directory named\ndjango.
To try out the in-development code with your own applications, simply place\nthe directory containing your clone on your Python import path. Then\nimport statements which look for Django will find the django module\nwithin your clone.
If you’re going to be working on Django’s code (say, to fix a bug or\ndevelop a new feature), you can probably stop reading here and move\nover to the documentation for contributing to Django, which covers things like the preferred\ncoding style and how to generate and submit a patch.
\nDjango uses branches to prepare for releases of Django (whether they be\nmajor or minor).
\nIn the past when Django was hosted on Subversion, branches were also used for\nfeature development. Now Django is hosted on Git and feature development is\ndone on contributor’s forks, but the Subversion feature branches remain in Git\nfor historical reference.
\nThese branches can be found in the repository as stable/A.B.x\nbranches and will be created right after the first alpha is tagged.
For example, immediately after Django 1.5 alpha 1 was tagged, the branch\nstable/1.5.x was created and all further work on preparing the code for the\nfinal 1.5 release was done there.
These branches also provide limited bugfix support for the most recent released\nversion of Django and security support for the two most recently-released\nversions of Django.
\nFor example, after the release of Django 1.5, the branch stable/1.5.x\nreceives only fixes for security and critical stability bugs, which are\neventually released as Django 1.5.1 and so on, stable/1.4.x receives only\nsecurity fixes, and stable/1.3.x no longer receives any updates.
Feature-development branches tend by their nature to be temporary. Some\nproduce successful features which are merged back into Django’s master to\nbecome part of an official release, but others do not; in either case there\ncomes a time when the branch is no longer being actively worked on by any\ndeveloper. At this point the branch is considered closed.
\nUnfortunately, Django used to be maintained with the Subversion revision\ncontrol system, that has no standard way of indicating this. As a workaround,\nbranches of Django which are closed and no longer maintained were moved into\nattic.
For reference, the following are branches whose code eventually became\npart of Django itself, and so are no longer separately maintained:
\nboulder-oracle-sprint: Added support for Oracle databases to\nDjango’s object-relational mapper. This has been part of Django\nsince the 1.0 release.
gis: Added support for geographic/spatial queries to Django’s\nobject-relational mapper. This has been part of Django since the 1.0\nrelease, as the bundled application django.contrib.gis.
i18n: Added internationalization support to\nDjango. This has been part of Django since the 0.90 release.
magic-removal: A major refactoring of both the internals and\npublic APIs of Django’s object-relational mapper. This has been part\nof Django since the 0.95 release.
multi-auth: A refactoring of Django’s bundled\nauthentication framework which added support for\nauthentication backends. This has\nbeen part of Django since the 0.95 release.
new-admin: A refactoring of Django’s bundled\nadministrative application. This became part of\nDjango as of the 0.91 release, but was superseded by another\nrefactoring (see next listing) prior to the Django 1.0 release.
newforms-admin: The second refactoring of Django’s bundled\nadministrative application. This became part of Django as of the 1.0\nrelease, and is the basis of the current incarnation of\ndjango.contrib.admin.
queryset-refactor: A refactoring of the internals of Django’s\nobject-relational mapper. This became part of Django as of the 1.0\nrelease.
unicode: A refactoring of Django’s internals to consistently use\nUnicode-based strings in most places within Django and Django\napplications. This became part of Django as of the 1.0 release.
When Django moved from SVN to Git, the information about branch merges wasn’t\npreserved in the source code repository. This means that the master branch\nof Django doesn’t contain merge commits for the above branches.
However, this information is available as a grafts file. You can restore it\nby putting the following lines in .git/info/grafts in your local clone:

\nfull-history
generic-auth
multiple-db-support
per-object-permissions
schema-evolution
schema-evolution-ng
search-api
sqlalchemy
All of the above-mentioned branches now reside in attic.
Finally, the repository contains soc2009/xxx and soc2010/xxx feature\nbranches, used for Google Summer of Code projects.
Each Django release is tagged and signed by a releaser.
\nThe tags can be found on GitHub’s tags page.
