The conditional processing decorator from r10114 wasn't parsing ETags
from an If-Match header correctly. Patch from Ivan Sagalaev (who also
did most of the work in r10114, before I rewrote parts of it and added
bonus bugs, although I forgot to thank him there).

This provides support for views that can have their ETag and/or Last-modified
values computed much more quickly than the view itself. Supports all HTTP
verbs (not just GET).
Documentation and tests need a little more fleshing out (I'm not happy with the
documentation at the moment, since it's a bit backwards), but the functionality
is correct.

Not sure if any of these are noticed as omissions yet; it's too new.
Primarily trying to head off questions in the future.

A custom manager on a related object that filtered away objects would prevent
those objects being deleted via the relation. This is now fixed.

Calling the super() version of __reduce__ in Model.__reduce__ led to infinite
loops in Python prior to 2.5. We don't do that any longer.

Previously on "things we changed in the recent past".... the database
connection setup was changed. People were happy. Except for those
running on Python 2.3.
We had completely broken Django on Python 2.3. Turns out, this is due to
a long-standing bug in the _threading_local module that interacts with
object creation in 2.3.
Interestingly, although the bug remains in Python 2.4 and 2.5, they
don't trip over it for reasons I don't entirely understand at the
moment.

Updated docs to reflect the change, and the fact that using the
two separate middleware is preferred to using the combined one.

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.

These features look similar, but they're not identical. They can't be merged
into one (without requiring at least two Meta parameters anyway), so we've made
them have APIs that match their natural use-cases most easily.
Anyway, the documentation explains both the details and gives some simple to
follow rules.

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.

Looks like we have to use the same format specifiers in both singular and
plural forms of a message or the PO file cannot be compiled to MO format. This
commit changes one place in admin that was using different specifiers.

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.

This is for Manager subclasses that are default managers, but only
sometimes. The general rule is: "don't use it." If you really need it,
read the instructions.
git-svn-id: http://code.djangoproject.com/svn/django/trunk@10057 bcc190cf-cafb-0310-a4f2-bffc1f526a37
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.)
