Affects the postgresql_psycopg2 backend only. We now don't use the
"RETURNING" syntax in SQL INSERT statements unless it's required by the
autocommit behaviour. This fixes an edge-case that could cause crashes
with earlier PostgreSQL versions, but the broader problem remains to be
fixed (which is #10509).
Fixed#10467. Refs #10509.

We can't use the default manager in Model.save_base(), since we need to
retrieve existing objects which might be filtered out by that manager. We now
always use a plain Manager instance at that point (or something that can
replace it, such as a GeoManager), making all existing rows in the
database visible to the saving code.
The logic for detecting a "suitable replacement" plain base is the same as for
related fields: if the use_for_related_fields is set on the manager subclass,
we can use it. The general requirement here is that we want a base class that
returns the appropriate QuerySet subclass, but does not restrict the rows
returned.
Fixed#8990, #9527.
Refs #2698 (which is not fixed by this change, but it's the first part of a
larger change to fix that bug.)

In order to report more comphrehensible tracebacks, remove the super()
constructor call, since passing args to object.__init__ ends badly. So some
subclassing possibilities are now removed, but it's the "dummy" backend, so
we can make some compromises.

This only shows up in for reverse() (not forwards resolving), since that
path uses a globally shared resolver object. Based on a patch from
Travis Terry.

I introduced a bad regression in r10029, forgetting to check that some
syntax was supported. For now, you can't use autocommit=True with 8.1
and earlier (it's still available for later versions). I'll fix the
broader issue later and re-enable it for those versions, but I want to
get the SQL regression for the default path out of the code right now.

There was a bug in the way we were reading the DATABASE_OPTIONS setting
and a lot of essentially duplicated code. This is neater.

Ensure to read the documentation before blindly enabling this: requires some
code audits first, but might well be worth it for busy sites.

This is backwards-compatible but will likely break third-party database backends. Specific API changes are:
* BaseDatabaseWrapper.__init__() now takes a settings_dict instead of a settings module. It's called settings_dict to disambiguate, and for easy grepability. This should be a dictionary containing DATABASE_NAME, etc.
* BaseDatabaseWrapper has a settings_dict attribute instead of an options attribute. BaseDatabaseWrapper.options is now BaseDatabaseWrapper['DATABASE_OPTIONS']
* BaseDatabaseWrapper._cursor() no longer takes a settings argument.
* BaseDatabaseClient.__init__() now takes a connection argument (a DatabaseWrapper instance) instead of no arguments.

Adding a get_db_prep_save() call to the UpdateQuery code path meant it
was being called twice if you updated an existing model attribute. This
change removes that double call and also makes TimeField.to_python() a
little more robust for the benefit of the Oracle backend (just in case).

This allows a model to be defined which is not subject to database table
creation and removal. Useful for models that sit over existing tables or
database views.

This removes a long-standing FIXME in the update() handling and allows for
greater flexibility in the values passed in. In particular, it brings updates
into line with saves for django.contrib.gis fields, so fixed#10411.

* All C API method explictly called from their prototype module, no longer imported via *.
* Applied DRY to C pointer management, classes that do so subclass from `GDALBase`.
* `OGRGeometry`: Added `from_bbox` class method (patch from Christopher Schmidt) and `kml` property.
* `SpatialReference`: Now initialize with `SetFromUserInput` (initialization is now more simple and flexible); removed duplicate methods.
* `Envelope`: Added `expand_to_include` method and now allow same coordinates for lower left and upper right points. Thanks to Paul Smith for tickets and patches.
* `OGRGeomType`: Now treat OGC 'Geometry' type as 'Unknown'.

Previously, you could explicitly assign None to a non-null ForeignKey
(or other) field when creating the model (Child(parent=None), etc). We
now throw an exception when you do that, which matches the behaviour
when you assign None to the attribute after creation.

This fixes a broad class of bugs involving filters that look for missing
related models and fields. Most of them don't seem to have been reported
(the added tests cover the root cause). The exception is that this has
also fixed#9868.

This was always not working reliably (model initialization and serialization
were two of the problems). Now, it's an explicit error. Also, documented.

Manually specifying both a OneToOneField(parent_link=True) and separate a
primary key field was causing invalid SQL to be generated. Thanks to Ramiro
Morales for some analysis on this one.

This includes a fairly large refactor of the update() query path (and
the initial portions of constructing the SQL for any query). The
previous code appears to have been only working more or less by accident
and was very fragile.
git-svn-id: http://code.djangoproject.com/svn/django/trunk@9967 bcc190cf-cafb-0310-a4f2-bffc1f526a37
If an update only affected an ancestor model (not the child), we were
returning 0 for the number of rows updated. This could have been
misleading if the value is used to detect an update occuring. So we now
return the rowcount from the first non-trivial query that is executed
(if any). Still a slight compromise, but better than what we had.

The patch is from Russell, but I'm applying it because I want my tests to pass
again (and he doesn't see the failure).

(Simultaneously, stop django.contrib.gis using some internal attribute when
there's a perfectly good public property available to do the same thing.)

This is like "safe", except it operates on the individual elements of a
sequence, rather than treating the whole argument as a string.

Now you can import the file storage stuff and still call settings.configure()
afterwards. There is still one import-time usage of settings in
django.contrib.comments, but that's unavoidable.

The cache tests have been failing for a long time with the db backend. This
change makes them pass again, so no test changes required here.

Allows us to reuse the same code in multiple places, avoiding new and
interesting bugs (the testing framework had a DIY version that was slightly
wrong, for example). Fixed#9833.

This permits running Django's core tests under an alternative test runner. Most
likely useful to non-CPython implementations, rather than much else (since
Django's core tests might assume things about the test runner).

Some results were inadvertently being excluded if we were ordering across a
nullable relation which itself ordering by a non-nullable relation.

In r9707 we added a preference to use Python's standard json module (Python 2.6
and beyond). However, there is also a third-party module called json that was
being picked up by accident if it was installed. It isn't API compatible, so
bad things happened. This change avoids that problem.

This avoids the problem of, for example, saving a change to the Site model in
the admin interface and then seeing the wrong instanec returned in the next
call to get_current_site().
It's still possible to end up with an inconsistent cache if update() is used to
change the Site model, but that's pretty unavoidable. It's also a slightly odd
way to update a Site model, so if you really need to do that, you can manage to
call SiteManager.clear() at the same time.
