Fixed #20483.

Aymeric Augustin 3634948c88 Moved IgnorePendingDeprecationWarningsMixin in django.test.utils.
This mixin is useful whenever deprecating a large part of Django.

Anssi Kääriäinen 6b4834952d Fixed #16649 -- Refactored save_base logic
Model.save() will use UPDATE - if not updated - INSERT instead of
SELECT - if found UPDATE else INSERT. This should save a query when
updating, but will cost a little when inserting model with PK set.

Also fixed #17341 -- made sure .save() commits transactions only after
the whole model has been saved. This wasn't the case in model
inheritance situations.

The save_base implementation was refactored into multiple methods.
A typical chain for inherited save is:
save_base()
    _save_parents(self)
        for each parent:
            _save_parents(parent)
            _save_table(parent)
    _save_table(self)

Aymeric Augustin 0cee3c0e43 Updated a test that doesn't make sense with autocommit. 2013-03-11 15:05:04 +01:00
Aymeric Augustin 7c46c8d5f2 Added some assertions to enforce the atomicity of atomic. 2013-03-11 14:48:55 +01:00
Aymeric Augustin 4b31a6a9e6 Added support for savepoints in SQLite.
Technically speaking they aren't usable yet.

Aymeric Augustin ba5138b1c0 Deprecated transaction.commit/rollback_unless_managed.
Since "unless managed" now means "if database-level autocommit",
committing or rolling back doesn't have any effect.

Restored transactional integrity in a few places that relied on
automatically-started transactions with a transitory API.

Aymeric Augustin af9e9386eb Enabled autocommit for PostgreSQL.
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.

Aymeric Augustin 8717b0668c Separated autocommit and isolation level handling for PostgreSQL.
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.

Aymeric Augustin 7aacde84f2 Made transaction.managed a no-op and deprecated it.
enter_transaction_management() was nearly always followed by managed().

In three places it wasn't, but they will all be refactored eventually.
The "forced" keyword argument avoids introducing behavior changes until
then.

This is mostly backwards-compatible, except, of course, for managed
itself. There's a minor difference in _enter_transaction_management:
the top self.transaction_state now contains the new 'managed' state
rather than the previous one. Django doesn't access
self.transaction_state in _enter_transaction_management.

Aymeric Augustin e0449316eb Fixed #18130 -- Made the isolation level configurable on PostgreSQL.
Thanks limscoder for the report and niwi for the draft patch.

Anssi Kääriäinen 50328f0a61 Fixed #19861 -- Transaction ._dirty flag improvement
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.
