Thanks russellm for report and Tim Graham for review.
2014-06-17 16:16:02 -04:00
Tim Graham 82c935d44c Renamed DatabaseFeature.supports_check_constraints to supports_column_check_constraints.

Shai Berger 612290400f Fixed #22816 -- Corrected Oracle feature flag and fixed introspection test 2014-06-14 00:43:49 +03:00
Aymeric Augustin 40bfd8561d Fixed #20420 -- Normalized query counts on Oracle.
This is achieved by inserting a fake entry in connection.queries when
not releasing a savepoint (since Oracle doesn't support that operation.)

Also removed the can_release_savepoints feature that was recently added,
but is superseded by this solution.
2014-06-09 21:38:10 +02:00
Aymeric Augustin 127218b92b Simplified handling of use_debug_cursor.
Turned it from a tri-valued boolean into a regular boolean.
2014-06-09 21:35:17 +02:00
Aymeric Augustin 58de495c54 Fixed #17427 -- Removed dubious definition of connections equality. 2014-06-07 17:04:10 +02:00
Aymeric Augustin cfcca7ccce Fixed #3711, #6734, #12581 -- Bounded connection.queries.

Thanks Rob, Alex, Baptiste, and others.

Aymeric Augustin e071f67b7f Replaced an explicit vendor check by a feature flag.
Forward-port of c9aedce0 from stable/1.7.x.
2014-06-06 00:32:13 +02:00
Aymeric Augustin a03d38ddd4 Added a flag for the ability to introspect nullable fields.
Previously this was conflated with another Oracle-specific behavior.
2014-06-05 17:56:56 +02:00
Shai Berger 69337d485c Set straight the sense of 'uppercases_column_names' feature flag 2014-05-28 21:16:24 +03:00
Andrew Godwin 1b07781292 Add feature for implied null (needed for Firebird backend) 2014-05-20 13:27:07 +01:00
Tim Martin 27aa85246a Fixed #20897 -- Added make_cursor() for consistent cursor creation
In django.db.backends.BaseDatabaseWrapper, pulled the creation of
cursors in the non-debug case into a separate method, in order to
make behavior more consistent when overriding the cursor creation
in derived classes.
2014-05-15 07:55:36 -04:00
Aymeric Augustin fb90b7cda2 Adjusted refactoring of vendor checks.
Thanks Shai for the thorough review.
2014-05-10 14:40:42 +02:00
Aymeric Augustin 99d9fa329a Added feature flags for introspection capabilities. 2014-05-08 22:11:20 +02:00
Aymeric Augustin cff59bedc2 Split ignores_nulls_in_unique_constraints feature.
Oracle and SQL Server don't have exactly the same limitations. It's
worth treating them differently.
2014-05-08 22:11:20 +02:00
Aymeric Augustin c70a61eb49 Replaced vendor checks by three feature flags. 2014-05-08 22:11:15 +02:00
Alex Gaynor 2bcb8bfc8d Fix many many typos in comments throughout the codebase 2014-04-26 10:18:45 -07:00
Aymeric Augustin 8b5b199e20 Fixed #3214 -- Stopped parsing SQL with regex.
Avoided introducing a new regex-based SQL splitter in the migrations
framework, before we're bound by backwards compatibility.

Adapted this change to the legacy "initial SQL data" feature, even
though it's already deprecated, in order to facilitate the transition
to migrations.

sqlparse becomes mandatory for RunSQL on some databases (all but
PostgreSQL). There's no API to provide a single statement and tell
Django not to attempt splitting. Since we have a more robust splitting
implementation, that seems like a good tradeoff. It's easier to add a
new keyword argument later if necessary than to remove one.

Many people contributed to both tickets, thank you all, and especially
Claude for the review.

Vajrasky Kok d3cf6cfacf Fixed #17713 -- Renamed BaseDatabaseFeatures.allows_primary_key_0 to allows_auto_pk_0.
MySQL does allow primary key with value 0. It only forbids autoincrement
primary key with value 0.

Thanks Claude Paroz for the report.

Michael Manfre 3ffeb93186 Ensure cursors are closed when no longer needed.
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()'.

Russell Keith-Magee d818e0c9b2 Fixed #16905 -- Added extensible checks (nee validation) framework

Apolloner, and Alex Gaynor for review notes along the way.

Also: Fixes #8579, fixes #3055, fixes #19844.

Anssi Kääriäinen 20bab2cf9d Fixed #16187 -- refactored ORM lookup system

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.

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 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
Aymeric Augustin 1716b7ce5a Renamed AppCache to Apps.
Also renamed app_cache to apps and "app cache" to "app registry".

Deprecated AppCache.app_cache_ready() in favor of Apps.ready().
2013-12-24 12:25:17 +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.
