Malcolm Tredinnick 014b961509 Typo fix for an error path in r100090.

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 5fb6667036 Fixed #3460 -- Added an ability to enable true autocommit for psycopg2 backend. 
Ensure to read the documentation before blindly enabling this: requires some
code audits first, but might well be worth it for busy sites.

Thanks to nicferrier, iamseb and Richard Davies for help with this patch.

Malcolm Tredinnick 3242df16e4 To avoid an unfortunately common user-error, rename QuerySet.as_sql(). 
This was never a public API method, so this is backwards compatible, unless
you're poking at the internals. Refs #10352.

Russell Keith-Magee 542709d0d1 Fixed #10182 -- Corrected realiasing and the process of evaluating values() for queries with aggregate clauses. This means that aggregate queries can now be used as subqueries (such as in an __in clause). Thanks to omat for the report. 
This involves a slight change to the interaction of annotate() and values() clauses that specify a list of columns. See the docs for details.

Previous behaviour was pretty stupid. Let's never speak of it again. New
behaviour both works and is documented.

Malcolm Tredinnick d068ad0c01 Using querysets as an rvalue in filter() calls was causing an unnecessary 
database query, due to a bool() call. This change stops that behaviour.

Malcolm Tredinnick f747b61c20 Nested query support. 
This extends previous functionality that allowed passing Query objects as the
rvals to filters. You can now pass QuerySets, which requires less poking at
opaque attributes. See the documentation of the "__in" lookup type for the
details.

Malcolm Tredinnick 44f228fd61 Fixed #6748 -- When printing the repr() of querysets, don't load or display 
more than 20 objects.

This means that accidentally executing HugeStoryArchive.objects.all() at the
interactive prompt (or in the debug template) won't try to load all 4,233,010
stories into memory and print them out. That would previously cause resource
starvation and other "interesting" crashes.

If you really, really want the previous behaviour (e.g. in a doctest that
prints more than 20 items), display "list(qs)" instead of just "qs".

Jacob Kaplan-Moss 7ecdf47bd0 Fixed #8115: avoid a infiniate loop when collecting related objects for deletion. 
I can't reproduce the original error leading to #8115 and the patch. However, the only harm this change could cause is to raise more `CyclicDependency` exceptions than strictly necessary. That's better than infinite loops, at least, and it's easier to clean up in the future when we figure out the actual fix.

Malcolm Tredinnick c181734fa1 Changed create() and get_or_create() to force an insert (not update an existing value). 
Backwards incompatible if you are using manually-specific primary key values
and relying on the previously documented behaviour that the new values would
always exist in the database (i.e. it would update the existing entry).

Fixed #8419.

Malcolm Tredinnick d4d7bc175d Fixed #8046 -- The first filter() call on a related manager for many-to-many 
fields no longer creates duplicate copies of the join table(s). Basically, this
means filters on the join table (for ManyToManyField(through=...)) and complex
filters in the normal (non-through) case don't produce incorrect or duplicate
results.

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).

Malcolm Tredinnick 002dbd16b4 Removed the bulk of the sanity checking when merging QuerySets. 
It was causing too many inconvenient and unintended problems when merging
legitimate subclasses (e.g. with geo-django classes). There's still a hook
there that we use when merging ValueQuerySets, but if you try to merge two
disparate QuerySets and it breaks all that happens is you get to keep both
pieces. We're no longer penalising the useful usages just for the people who
aren't concentrating.

Fixed #7113.
