Replaced the custom, untested memoize with a similar decorator from Python's
3.2 stdlib. Although some minor performance degradation (see ticket), it is
expected that in the long run lru_cache will outperform memoize once it is
implemented in C.
Thanks to EvilDMP for the report and Baptiste Mispelon for the idea of
replacing memoize with lru_cache.
This patch introduces the Prefetch object which allows customizing prefetch
operations.
This enables things like filtering prefetched relations, calling select_related
from a prefetched relation, or prefetching the same relation multiple times
with different querysets.
When a Prefetch instance specifies a to_attr argument, the result is stored
in a list rather than a QuerySet. This has the fortunate consequence of being
significantly faster. The preformance improvement is due to the fact that we
save the costly creation of a QuerySet instance.
Thanks @akaariai for the original patch and @bmispelon and @timgraham
for the reviews.
``ModelAdmin.view_on_site`` defines wether to show a link to the object on the
admin detail page. If ``True``, cleverness (i.e. ``Model.get_absolute_url``) is
used to get the url. If it's a callable, the callable is called with the object
as the only parameter. If ``False``, not link is displayed.
With the aim of maitaining backwards compatibility, ``True`` is the default.
`HttpRequest.scheme` is `https` if `settings.SECURE_PROXY_SSL_HEADER` is
appropriately set and falls back to `HttpRequest._get_scheme()` (a hook
for subclasses to implement) otherwise.
`WSGIRequest._get_scheme()` makes use of the `wsgi.url_scheme` WSGI
environ variable to determine the request scheme.
`HttpRequest.is_secure()` simply checks if `HttpRequest.scheme` is
`https`.
This provides a way to check the current scheme in templates, for example.
It also allows us to deal with other schemes.
Thanks nslater for the suggestion.
Added a validation error check when creating the permissions for model, to avoid
cryptic database error when the verbose_name is longer than 39 characters
thanks elena for reporting it
The package renaming restores the older package names (which were also the
documented package names). This doesn't affect test discovery because the
module in question doesn't contain any tests.
Thanks to Carl for the design discussion.
Don't set a global default interpreted role function for reStructuredText.
Instead, use the `default-role` directive to change the default only within
the `parse_rst()` function.
Thanks Malcolm Tredinnick for the report.

Clarified interactions between atomic and exceptions.

Fixed TransactionManagementError in tests.
Previous commit introduced an additional check to prevent running
queries in transactions that will be rolled back, which triggered a few
failures in the tests. In practice using transaction.atomic instead of
the low-level savepoint APIs was enough to fix the problems.

Allowed nesting constraint_checks_disabled inside atomic.
Since MySQL handles transactions loosely, this isn't a problem.
commit 2a4ab1cb6e83391ff7e25d08479e230ca564bfef

Prevented running queries in transactions that will be rolled back.
This avoids a counter-intuitive behavior in an edge case on databases
with non-atomic transaction semantics.
It prevents using savepoint_rollback() inside an atomic block without
calling set_rollback(False) first, which is backwards-incompatible in
tests.

commit 8e3db393853c7ac64a445b66e57f3620a3fde7b0

Replaced manual savepoints by atomic blocks.
This ensures the rollback flag is handled consistently in internal APIs.
This reverts commit aae5a96d57.
This fix is no longer necessary, our pbkdf2 (see next commit) implementation
no longer rehashes the password every iteration.
tearDownClass is not called if setUpClass throws an exception, in our case
this means that LiveServerTestCase leaks LiveServerThread sockets if the
test happens to be skipped later on, and AdminSeleniumWebDriverTestCase
doesn't close it's already open browser window. To prevent this leakage
we catch errors where needed and manually call _tearDownClassInternal.
_tearDownClassInternal should be written as defensively as possible since
it is not allowed to make any assumptions on how far setUpClass got.
This patch should fix the sporadic "Address already in use"-errors on jenkins
and also the "This code isn't under transaction management"-error for sqlite
(also just on jenkins).
After discussion with koniiiik, jezdez, kmtracey, tos9, lifeless, nedbat and
voidspace it was decided that this is the safest approach (thanks to everyone
for their comments and help). Manually calling tearDownClass was shut down
cause we don't know how our users override our classes.
This is a private and very specialized API on purpose and should not be used
without a strong reason!
This patch partially reverts the earlier attempts to fix those issues,
namely:
2fa0dd73b1 and
3c5775d36f
Final note: If this patch breaks in a later version of Django, please be
very careful on how you fix it, you might not see test failures locally.
That said, this patch hopefully doesn't produce even more failures.
* Limit the password length to 4096 bytes
* Password hashers will raise a ValueError
* django.contrib.auth forms will fail validation
* Document in release notes that this is a backwards incompatible change
Thanks to Josh Wright for the report, and Donald Stufft for the patch.
This is a security fix; disclosure to follow shortly.
If setUpClass throws an exception (in this case "Address already in use" if the
super call can't find any open port to bind too) tearDownClass is not called.
This results in open browser windows from the webdriver, hence we only construct
it once we are sure there is no code afterwards which could error out.
We want to be able to use it for instance for discovering `tasks.py` modules
inside the INSTALLED_APPS.
This commit therefore moves the logic to `autodiscover_modules` method in
django.utils.module_loading.
The Admin widget, which can be used to filter multiple selects
can sometimes be too narrow and hide information such as
user permissions. This commit adds tooltips to the select
options so that a user can hover over and see the hidden text.
AdminSite now has overridable site_header, site_title and index_title attributes. Changed
each admin view to pass these to the context (in a new AdminSite.each_context() method).
The intent here is to make it easier to override these things in the common case, instead of
having to override a template, which is a bigger burden.
