Ramiro Morales f758bdab5e Fixed #18271 -- Changed stage at which TransactionTestCase flushes DB tables.
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.

Anssi Kääriäinen a18e43c5bb Made get_indexes() consistent across backends.
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.

For this, the ``distinct()`` QuerySet method now accepts an optional

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

Aymeric Augustin 549c495875 Used symbolic constants for psycopg2 isolation levels.
Django used the value 1 = ISOLATION_LEVEL_READ_UNCOMMITTED in some places, but
PostgreSQL doesn't provide "read uncommited", it uses "read committed" instead:
http://www.postgresql.org/docs/9.1/static/transaction-iso.html. For clarity,
this commit uses ISOLATION_LEVEL_READ_COMMITTED = 2 where 1 was previously used.

Ramiro Morales 569aa34ea5 Fixed #16250 -- Made test database creation support code in the PostgreSQL DB backend compatible with psycopg2 2.4.2.
Implemented this by adding an internal hook for work that should be performed
before that point.

Also, regarding the `DatabaseCreation.set_autocommit()` method:
 * Stop using it for such tasks
 * Stop providing an implementation that tries to cover all the possible
   idioms a third party database backend DB-API 2 driver could need to activate
   autocommit. It is now left for third party backends to implement.

This can be backwards incompatible in the case of user applications that:
 * Had started using this method
 * Use a third a party database backend

Ramiro Morales f2dca72afd Fixed #11065, #11285 -- Streamlined PostgreSQL version detection, fixing incompatibility with multi-db. Thanks findepi for the report.
Changed our internal representation of the PostgreSQL version from tuples to
integers as used by libpq and psycopg2. This simplifies version comparison
operations.

Also, using the associated libpq/psycopg2 API allows to remove the need for
manually issuing in-band ``SELECT version()`` SQL queries to obtain the server
version (or at least reduce its number if version of psycopg2 in use is older
than 2.0.12). Refs #10509.

Malcolm Tredinnick 536ccd1134 More fixing of PostgreSQL < 8.2 problems with the psycopg2 backend.
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.

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.

This will make it easier for multiple database support. Thanks to Alex Gaynor for the initial patch.
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.

Malcolm Tredinnick 220993bcc5 Added savepoint support to the transaction code.
This is a no-op for most databases. Only necessary on PostgreSQL so that we can
do things which will possibly intentionally raise an IntegrityError and not
have to rollback the entire transaction. Not supported for PostgreSQL versions
prior to 8.0, so should be used sparingly in internal Django code.

Adrian Holovaty c599de2ac6 Added a BaseDatabaseOperations.last_executed_query() hook, which allows a database backend to specify how to get the last-executed query on a given cursor.
