Change database test settings from "TEST_"-prefixed entries in the
database settings dictionary to setting in a dictionary that is itself
an entry "TEST" in the database settings.
Refs #21775
Thanks Josh Smeaton for review.
This commit touchs various parts of the code base and test framework. Any
found usage of opening a cursor for the sake of initializing a connection
has been replaced with 'ensure_connection()'.
Allowed users to specify which lookups or transforms ("nested lookus")
are available for fields. The implementation is now class based.

Mostly just formatting and rewording, but also replaced the example
using ``YearExtract`` to use an example which is unlikely to ever be
possible directly in the ORM.

Altered query string customization for backends vendors
The new way is trying to call first method 'as_' + connection.vendor.
If that doesn't exist, then call as_sql().
Also altered how lookup registration is done. There is now
RegisterLookupMixin class that is used by Field, Extract and
sql.Aggregate. This allows one to register lookups for extracts and
aggregates in the same way lookup registration is done for fields.

Initial implementation of custom lookups
Also ensured the transaction state is clean on Oracle while I was there.
This change cannot be backported to 1.6 because it's
backwards-incompatible for custom database backends.
When settings.DATABASES['default']['AUTOCOMMIT'] = False, the connection
wasn't in autocommit mode but Django pretended it was.
Thanks Anssi for analysing this issue.
Refs #17062.
This allows using flush on a subset of the tables without having to
manually cascade to all tables with foreign keys to the tables being
truncated, when they're known to be empty.
On databases where truncate is implemented with DELETE FROM, this
doesn't make a difference. The cascade is allowed, not mandatory.
For users who didn't activate autocommit in their database options, this
is backwards-incompatible in "non-managed" aka "auto" transaction state.
This state now uses database-level autocommit instead of ORM-level
autocommit.
Also removed the uses_autocommit feature which lost its purpose.
Autocommit cannot be manipulated independently from an open connection.
This commit introduces a minor change in behavior: entering transaction
management forces opening a databasse connection. This shouldn't be
backwards incompatible in any practical use case.
* Grouped related methods together -- with banner comments :/
* Described which methods are intended to be implemented in backends.
* Added docstrings.
* Used the same order in all wrappers.

Wrapped database exceptions in the base backend.
This covers the most common PEP-249 APIs:
- Connection APIs: close(), commit(), rollback(), cursor()
- Cursor APIs: callproc(), close(), execute(), executemany(),
fetchone(), fetchmany(), fetchall(), nextset().
Fixed#19920.
commit a66746bb5f0839f35543222787fce3b6a0d0a3ea
Author: Aymeric Augustin <aymeric.augustin@m4x.org>
Date: Tue Feb 26 14:53:34 2013 +0100
Added a wrap_database_exception context manager and decorator.
It re-throws backend-specific exceptions using Django's common wrappers.
There were a couple of errors in ._dirty flag handling:
* It started as None, but was never reset to None.
* The _dirty flag was sometimes used to indicate if the connection
was inside transaction management, but this was not done
consistently. This also meant the flag had three separate values.
* The None value had a special meaning, causing for example inability
to commit() on new connection unless enter/leave tx management was
done.
* The _dirty was tracking "connection in transaction" state, but only
in managed transactions.
* Some tests never reset the transaction state of the used connection.
* And some additional less important changes.
This commit has some potential for regressions, but as the above list
shows, the current situation isn't perfect either.
Thanks Carl Meyer for the review.

commit 29413eab2b
Author: Aymeric Augustin <aymeric.augustin@m4x.org>
Date: Sun Feb 10 16:15:49 2013 +0100
Documented QuerySet.datetimes and updated QuerySet.dates.
Connection creation was done in db backend ._cursor() call. This
included taking a new connection if needed, initializing the session
state for the new connection and finally creating the connection.
To allow easier modifying of these steps in subclasses (for example to
support connection pools) the _cursor() now calls get_new_connection()
and init_connection_state() if there isn't an existing connection. This
was done for all non-gis core backends. In addition the parameters used
for taking a connection are now created by get_connection_params().
We should also do the same for gis backends and encourage 3rd party
backends to use the same pattern. The pattern is not enforced in code,
and as the backends are private API this will not be required by
documentation either.
Previously, the flush was done before the test case execution and now
it is performed after it.
Other changes to the testing infrastructure include:
* TransactionTestCase now doesn't reset autoincrement sequences either
(previous behavior can achieved by using `reset_sequences`.)
With this, no implicit such reset is performed by any of the provided
TestCase classes.
* New ordering of test cases: All unittest tes cases are run first and
doctests are run at the end.
THse changes could be backward-incompatible with test cases that relied
on some kind of state being preserved between tests. Please read the
relevant sections of the release notes and testing documentation for
further details.
Thanks Andreas Pelme for the initial patch. Karen Tracey and Anssi
Kääriäinen for the feedback and Anssi for reviewing.
This also fixes#12408.
Fixed#15933, #18082 -- the get_indexes() method introspection was
done inconsitently depending on the backend. For example SQLite
included all the columns in the table in the returned dictionary,
while MySQL introspected also multicolumn indexes.
All backends return now consistenly only single-column indexes.
Thanks to andi for the MySQL report, and ikelly for comments on
Oracle's get_indexes() changes.
Thanks bthomas AT ncorcle DOT com for the report and initial patch, and
Claude Paroz for the final, complete patch.

only consider some fields (PostgreSQL only).
For this, the ``distinct()`` QuerySet method now accepts an optional

these cases. Thanks Jeffrey Gelens and Anssi Kääriäinen for their work.
