All adhoc MAC applications have been updated to use HMAC, using SHA1 to
generate unique keys for each application based on the SECRET_KEY, which is
common practice for this situation. In all cases, backwards compatibility
with existing hashes has been maintained, aiming to phase this out as per
the normal deprecation process. In this way, under most normal
circumstances the old hashes will have expired (e.g. by session expiration
etc.) before they become invalid.
In the case of the messages framework and the cookie backend, which was
already using HMAC, there is the possibility of a backwards incompatibility
if the SECRET_KEY is shorter than the default 50 bytes, but the low
likelihood and low impact meant compatibility code was not worth it.
All known instances where tokens/hashes were compared using simple string
equality, which could potentially open timing based attacks, have also been
fixed using a constant-time comparison function.
There are no known practical attacks against the existing implementations,
so these security improvements will not be backported.

Many thanks to gabrielhurley for putting most of this together. Also to
bmihelac, arthurk, qingfeng, hvendelbo, petr.pulc@s-cape.cz, Hraban for
reports and some initial patches.
The patch also contains some whitespace/PEP8 fixes.

The new behavior still disallows redirects to off-site URLs, but now allows
redirects of the form `/some/other/view?foo=http://...`.
Thanks to brutasse.

This is really just a stop-gap until we come up with a improved way of handling
disparate auth data, but it should help us stretch a bit more milage out of the
current system.
Thanks to alextreme, lbruno, and clayg.

This is a BACKWARDS INCOMPATIBLE change, because it removes the flawed
'auto_adapt_to_methods' decorator, and replaces it with 'method_decorator'
which must be applied manually when necessary, as described in the 1.2
release notes.
For users of 1.1 and 1.0, this affects the decorators:
* login_required
* permission_required
* user_passes_test
For those following trunk, this also affects:
* csrf_protect
* anything created with decorator_from_middleware
If a decorator does not depend on the signature of the function it is
supposed to decorate (for example if it only does post-processing of the
result), it will not be affected.

This monster of a patch is the result of Alex Gaynor's 2009 Google Summer of Code project.
Congratulations to Alex for a job well done.
Big thanks also go to:
* Justin Bronn for keeping GIS in line with the changes,
* Karen Tracey and Jani Tiainen for their help testing Oracle support
* Brett Hoerner, Jon Loyens, and Craig Kimmerer for their feedback.
* Malcolm Treddinick for his guidance during the GSoC submission process.
* Simon Willison for driving the original design process
* Cal Henderson for complaining about ponies he wanted.
... and everyone else too numerous to mention that helped to bring this feature into fruition.

This deprecates User.message_set in favour of a configurable messaging
system, with backends provided for cookie storage, session storage and
backward compatibility.
Many thanks to Tobias McNulty for the bulk of the work here, with
contributions from Chris Beaven (SmileyChris) and lots of code review from
Russell Keith-Magee, and input from many others. Also credit to the authors
of various messaging systems for Django whose ideas may have been pinched
:-)

There is stub code for backwards compatiblity with Django 1.1 imports.
The documentation has been updated, but has been left in
docs/contrib/csrf.txt for now, in order to avoid dead links to
documentation on the website.

This is a large change to CSRF protection for Django. It includes:
* removing the dependency on the session framework.
* deprecating CsrfResponseMiddleware, and replacing with a core template tag.
* turning on CSRF protection by default by adding CsrfViewMiddleware to
the default value of MIDDLEWARE_CLASSES.
* protecting all contrib apps (whatever is in settings.py)
using a decorator.
For existing users of the CSRF functionality, it should be a seamless update,
but please note that it includes DEPRECATION of features in Django 1.1,
and there are upgrade steps which are detailed in the docs.
Many thanks to 'Glenn' and 'bthomas', who did a lot of the thinking and work
on the patch, and to lots of other people including Simon Willison and
Russell Keith-Magee who refined the ideas.
Details of the rationale for these changes is found here:
http://code.djangoproject.com/wiki/CsrfProtection
As of this commit, the CSRF code is mainly in 'contrib'. The code will be
moved to core in a separate commit, to make the changeset as readable as
possible.

This *is* backwards compatible, but `admin.site.root()` has been deprecated. The new style is `('^admin/', include(admin.site.urls))`; users will need to update their code to take advantage of the new customizable admin URLs.
Thanks to Alex Gaynor.

When calling User.get_profile(), we now tell the profile object about the
related User object right away. This can save a database lookup later if
something in the user profile object wants to refer to the user object.
Patch from Mike Malone.
git-svn-id: http://code.djangoproject.com/svn/django/trunk@9152 bcc190cf-cafb-0310-a4f2-bffc1f526a37
* Removed `Manipulator`, `AutomaticManipulator`, and related classes.
* Removed oldforms specific bits from model fields:
* Removed `validator_list` and `core` arguments from constructors.
* Removed the methods:
* `get_manipulator_field_names`
* `get_manipulator_field_objs`
* `get_manipulator_fields`
* `get_manipulator_new_data`
* `prepare_field_objs_and_params`
* `get_follow`
* Renamed `flatten_data` method to `value_to_string` for better alignment with its use by the serialization framework, which was the only remaining code using `flatten_data`.
* Removed oldforms methods from `django.db.models.Options` class: `get_followed_related_objects`, `get_data_holders`, `get_follow`, and `has_field_type`.
* Removed oldforms-admin specific options from `django.db.models.fields.related` classes: `num_in_admin`, `min_num_in_admin`, `max_num_in_admin`, `num_extra_on_change`, and `edit_inline`.
* Serialization framework
* `Serializer.get_string_value` now calls the model fields' renamed `value_to_string` methods.
* Removed a special-casing of `models.DateTimeField` in `core.serializers.base.Serializer.get_string_value` that's handled by `django.db.models.fields.DateTimeField.value_to_string`.
* Removed `django.core.validators`:
* Moved `ValidationError` exception to `django.core.exceptions`.
* For the couple places that were using validators, brought over the necessary code to maintain the same functionality.
* Introduced a SlugField form field for validation and to compliment the SlugField model field (refs #8040).
* Removed an oldforms-style model creation hack (refs #2160).

sesssion. This means the user will see their session preserved across a login
boundary, but somebody snooping the anonymous session key won't be able to view
the authenticated session data.
This is the final piece of the session key handling changes.

session and a different user id to the current session owner, flush the session
data to avoid leakage. Logging in and moving from an anonymous user to a
validated user still keeps existing session data.
Backwards incompatible if you were assuming sessions persisted past logout.

Though some attempts and backwards-compatibility were made, speed trumped compatibility. Thus, as usual, check BackwardsIncompatibleChanges for the complete list of backwards-incompatible changes.
Thanks to Jeremy Dunck and Keith Busell for the bulk of the work; some ideas from Brian Herring's previous work (refs #4561) were incorporated.
Documentation is, sigh, still forthcoming.
Fixes#6814 and #3951 (with the new dispatch_uid argument to connect).
