Adrian Holovaty 5ceed0a053 Changed a whole bunch of places to raise exception instances instead of old-style raising exception classes plus a comma. Good for the future Python 3 conversion

Jacob Kaplan-Moss 20ad30713e Fixed #11863: added a `Model.objects.raw()` method for executing raw SQL queries and yield models.
See `docs/topics/db/raw.txt` for details.

Thanks to seanoc for getting the ball rolling, and to Russ for wrapping things up.

Malcolm Tredinnick 29050ef999 Fixed #5420 -- Added support for delayed loading of model fields.
In extreme cases, some fields are expensive to load from the database
(e.g. GIS fields requiring conversion, or large text fields). This
commit adds defer() and only() methods to querysets that allow the
caller to specify which fields should not be loaded unless they are
accessed.

Malcolm Tredinnick 61a2708c41 Fixed #10356 -- Added pure-Python inheritance for models (a.k.a proxy models).
Large portions of this are needed for #5420, so I implemented it fully.
Thanks to Ryan Kelly for an initial patch to get this started.

Refs #5420.

Malcolm Tredinnick 7d9b29a56d Use plain model.Manager, or suitable proxy, for model saving.
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.)

Malcolm Tredinnick f31425e8e2 Fixed #7154 -- Inherit all model managers from abstract base classes.
Also added documentation describing how manager inheritance works (and when
manager aren't inherited). Based on some patches from sebastian_noack and
emulbreh.

Jacob Kaplan-Moss 34a3bd5225 Major refactoring of django.dispatch with an eye towards speed. The net result is that signals are up to 90% faster.
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).
