commit f2dc4429a1
Author: Marc Tamlyn <marc.tamlyn@gmail.com>
Date:   Sun Jan 12 13:15:05 2014 +0000

    Reworked custom lookups docs.

    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.

commit c7d5f8661b
Author: Anssi Kääriäinen <akaariai@gmail.com>
Date:   Sat Jan 11 14:45:53 2014 +0200

    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
2014-01-18 11:46:19 +02:00
Aymeric Augustin fbe1abac4a Fixed #21453 -- Enabled autocommit before calling init_connection_state.
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.
2014-01-12 20:31:07 +01:00
Aymeric Augustin 1afe748832 Fixed #21452 -- Non-autocommit connections to PostgreSQL.
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.
2014-01-12 18:28:51 +01:00
Aymeric Augustin bfcc686d22 Removed the only_with_models_module argument of get_model[s].
Now that the refactorings are complete, it isn't particularly useful any
more, nor very well named. Let's keep the API as simple as possible.

Fixed #21689.
2013-12-30 23:59:34 +01:00
Aymeric Augustin 856aaaf2b1 Changed get_migratable_models to use an app config. 2013-12-29 21:25:28 +01:00
Ramiro Morales 5782c94f23 Added generation of SQLite FK DDL in initial migrations.
SQLite accepts the relevant standard SQL (although by default it doesn't
enforce the constraint), and the 'traditional' creation backend helper
generate it, so this allows us to:

- Maintain the status quo
- Improve readability of the SQL code generated for that backend.

Also, we will need this for when we fix Refs #14204.
2013-12-28 18:00:16 -03:00
Ramiro Morales 6a6136141b Implemented #10164 for new schema migration code.
Made it use 'AUTOINCREMENT' suffix for PK creation. This way it doeesn't

infrastructure.

Aymeric Augustin 2fef9e5375 Moved apps back in the toplevel django namespace.
Reverted 4a56a93cc4.
2013-12-22 11:39:55 +01:00
Aymeric Augustin 0242c56fd8 Deborgified the app cache.
Improved Andrew's hack to create temporary app caches to handle
migrations. Now the main app cache has a "master" flag set to True
(which is a non-default keyword argument, thus unlikely to be used by
mistake). Other app cache instances have "master" set to False.

The only sanctioned way to access the app cache is by importing
django.core.apps.app_cache.

If you were instanciating an app cache and relying on the Borg pattern,
you'll have to refactor your code.

Aymeric Augustin 4a56a93cc4 Moved the new app cache inside core. 2013-12-17 10:17:46 +01:00
Aymeric Augustin 5ba743e262 Made it possible to create apps without a models module.
This commit reverts f44c4a5d0f and 39bbd165.

django.test.simple will be updated in a separate commit as it requires
invasive changes.
2013-12-17 10:17:45 +01:00
Aymeric Augustin 2732edc5f2 Deprecated get_apps(). 2013-12-17 10:17:45 +01:00
Aymeric Augustin 8662654d6d Removed module-level functions for the app cache.
Since the original ones in django.db.models.loading were kept only for
backwards compatibility, there's no need to recreate them. However, many
internals of Django still relied on them.

They were also imported in django.db.models. They never appear in the
documentation, except a quick mention of get_models and get_app in the
1.2 release notes to document an edge case in GIS. I don't think that
makes them a public API.

This commit doesn't change the overall amount of global state but
clarifies that it's tied to the app_cache object instead of hiding it
behind half a dozen functions.
2013-12-17 10:17:44 +01:00
Aymeric Augustin 860c2c8bc5 Moved django.db.models.loading to django.apps.cache.
This commit doesn't contain any code changes; it's purely a refactoring.

Squashed commit of the following:

commit 63ddb271a44df389b2c302e421fc17b7f0529755
Author: Aymeric Augustin <aymeric.augustin@m4x.org>
Date:   Sun Sep 29 22:51:00 2013 +0200

    Clarified interactions between atomic and exceptions.

commit 2899ec299228217c876ba3aa4024e523a41c8504
Author: Aymeric Augustin <aymeric.augustin@m4x.org>
Date:   Sun Sep 22 22:45:32 2013 +0200

    Fixed TransactionManagementError in tests.

    Previous commit introduced an additional check to prevent running
    queries in transactions that will be rolled back, which triggered a few
    failures in the tests. In practice using transaction.atomic instead of
    the low-level savepoint APIs was enough to fix the problems.

commit 4a639b059ea80aeb78f7f160a7d4b9f609b9c238
Author: Aymeric Augustin <aymeric.augustin@m4x.org>
Date:   Tue Sep 24 22:24:17 2013 +0200

    Allowed nesting constraint_checks_disabled inside atomic.

    Since MySQL handles transactions loosely, this isn't a problem.

commit 2a4ab1cb6e83391ff7e25d08479e230ca564bfef
Author: Aymeric Augustin <aymeric.augustin@m4x.org>
Date:   Sat Sep 21 18:43:12 2013 +0200

    Prevented running queries in transactions that will be rolled back.

    This avoids a counter-intuitive behavior in an edge case on databases
    with non-atomic transaction semantics.

    It prevents using savepoint_rollback() inside an atomic block without
    calling set_rollback(False) first, which is backwards-incompatible in
    tests.

    Refs #21134.

Author: Aymeric Augustin <aymeric.augustin@m4x.org>

    Replaced manual savepoints by atomic blocks.

    This ensures the rollback flag is handled consistently in internal APIs.

Aymeric Augustin 13b7f299de Added a stealth option to flush to allow cascades.
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.

will happen).

Aymeric Augustin 93af822c00 Improved recovery when the connection is closed in an atomic block. 2013-03-13 15:17:40 +01:00
Aymeric Augustin 83a416f5e7 Made atomic usable when autocommit is off.
Thanks Anssi for haggling until I implemented this.

This change alleviates the need for atomic_if_autocommit. When
autocommit is disabled for a database, atomic will simply create and
release savepoints, and not commit anything. This honors the contract of
not doing any transaction management.

This change also makes the hack to allow using atomic within the legacy
transaction management redundant.

None of the above will work with SQLite, because of a flaw in the design
of the sqlite3 library. This is a known limitation that cannot be lifted
without unacceptable side effects eg. triggering arbitrary commits.

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.

automatically-started transactions with a transitory API.
2013-03-11 14:48:54 +01:00

Aymeric Augustin 5e27debc5c Enabled database-level autocommit for all backends.
This is mostly a documentation change.

It has the same backwards-incompatibility consequences as those
described for PostgreSQL in a previous commit.
2013-03-11 14:48:54 +01:00
Aymeric Augustin cfc114e00e Removed _enter/_leave_transaction_management.

implementation.
2013-03-11 14:48:54 +01:00
Aymeric Augustin 1617557ae3 Added BaseDatabaseWrapper.ensure_connection.
This API is useful because autocommit cannot be managed without an open
connection.

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.
2013-03-11 14:48:54 +01:00
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.
2013-03-11 14:48:54 +01:00
Aymeric Augustin f515619494 Added an API to control database-level autocommit. 2013-03-11 14:48:53 +01:00

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.

commit 524bc7345a724bf526bdd2dd1bcf5ede67d6bb5c
Author: Aymeric Augustin <aymeric.augustin@m4x.org>
Date:   Tue Feb 26 14:55:10 2013 +0100

    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

    It re-throws backend-specific exceptions using Django's common wrappers.
2013-02-27 17:26:54 +01:00
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.

Aymeric Augustin aea98e8c53 Simplified MySQL version checking.
Django used to check the version of MySQL before handling the first
request, which required:
- opening a connection
- closing it, to avoid holding it idle until the first request.

This code isn't necessary any longer since Django dropped support for
some versions of MySQL, and other database backends don't implement a
similar dance. For consistency and maintenability, remove it.

Anssi Kääriäinen 12a96bfa26 Fixed #19197 -- fixed convert_values() for nullable numeric fields
Cleaned up the implementation of base convert_values() a little, and
made sure it accepts None as a value for numeric fields.

There are no tests attached. The reason is that not all of the
convert_values() accept None as a value for numeric fields (for example
sqlite3.convert_values()).

The reason the base convert_values() needs to accept None is that this
situation might arise in custom compilers for 3rd party backends. It
is easy to keep the convert_values() working, so lets do that.

Anssi Kääriäinen 1893467784 Fixed #19274 -- Made db connection creation overridable in subclasses
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.
