Welcome to Django 1.2.4!
This is the fourth "bugfix" release in the Django 1.2 series, improving the stability and performance of the Django 1.2 codebase.
With one exception, Django 1.2.4 maintains backwards compatibility with Django 1.2.3. It also contains a number of fixes and other improvements. Django 1.2.4 is a recommended upgrade for any development or deployment currently using or targeting Django 1.2.
For full details on the new features, backwards incompatibilities, and deprecated features in the 1.2 branch, see the Django 1.2 release notes.
The Django administrative interface, django.contrib.admin, supports
filtering of displayed lists of objects by fields on the corresponding
models, including across database-level relationships. This is
implemented by passing lookup arguments in the querystring portion of
the URL, and options on the ModelAdmin class allow developers to
specify particular fields or relationships which will generate
automatic links for filtering.
One historically-undocumented and -unofficially-supported feature has been the ability for a user with sufficient knowledge of a model's structure and the format of these lookup arguments to invent useful new filters on the fly by manipulating the querystring.
However, it has been demonstrated that this can be abused to gain access to information outside of an admin user's permissions; for example, an attacker with access to the admin and sufficient knowledge of model structure and relations could construct query strings which -- with repeated use of regular-expression lookups supported by the Django database API -- expose sensitive information such as users' password hashes.
To remedy this, django.contrib.admin will now validate that
querystring lookup arguments either specify only fields on the model
being viewed, or cross relations which have been explicitly
whitelisted by the application developer using the pre-existing
mechanism mentioned above. This is backwards-incompatible for any
users relying on the prior ability to insert arbitrary lookups.
Ordinarily, a point release would not include new features, but in the case of Django 1.2.4, we have made an exception to this rule.
One of the bugs fixed in Django 1.2.4 involves a set of
circumstances whereby a running a test suite on a multiple database
configuration could cause the original source database (i.e., the
actual production database) to be dropped, causing catastrophic loss
of data. In order to provide a fix for this problem, it was necessary
to introduce a new setting -- TEST_DEPENDENCIES -- that
allows you to define any creation order dependencies in your database
configuration.
Most users -- even users with multiple-database configurations -- need
not be concerned about the data loss bug, or the manual configuration of
TEST_DEPENDENCIES. See the original problem report
documentation on controlling the creation order of test
databases for details.
The function-based TEST_RUNNER previously used to execute
the GeoDjango test suite, django.contrib.gis.tests.run_gis_tests,
was finally deprecated in favor of a class-based test runner,
django.contrib.gis.tests.GeoDjangoTestSuiteRunner, added in this
release.
In addition, the GeoDjango test suite is now included when
running the Django test suite with runtests.py
and using spatial database backends.
