2013-02-27Refactored database exceptions wrapping.Aymeric Augustin
Squashed commit of the following: commit 2181d833ed1a2e422494738dcef311164c4e097e Author: Aymeric Augustin <aymeric.augustin@m4x.org> Date: Wed Feb 27 14:28:39 2013 +0100 Fixed #15901 -- Wrapped all PEP-249 exceptions. commit 5476a5d93c19aa2f928c497d39ce6e33f52694e2 Author: Aymeric Augustin <aymeric.augustin@m4x.org> Date: Tue Feb 26 17:26:52 2013 +0100 Added PEP 3134 exception chaining. Thanks Jacob Kaplan-Moss for the suggestion. commit 9365fad0a650328002fb424457d675a273c95802 Author: Aymeric Augustin <aymeric.augustin@m4x.org> Date: Tue Feb 26 17:13:49 2013 +0100 Improved API for wrapping database errors. Thanks Alex Gaynor for the proposal. commit 1b463b765f2826f73a8d9266795cd5da4f8d5e9e Author: Aymeric Augustin <aymeric.augustin@m4x.org> Date: Tue Feb 26 15:00:39 2013 +0100 Removed redundant exception wrapping. This is now taken care of by the cursor wrapper. 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 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.
2013-02-27Fixed #19861 -- Transaction ._dirty flag improvementAnssi Kääriäinen
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.
2013-02-25Fixed #19634 -- Added proper __hash__ methods.Aymeric Augustin
Classes overriding __eq__ need a __hash__ such that equal objects have the same hash. Thanks akaariai for the report and regebro for the patch.

2013-02-23Fixed Oracle regression in last_executed_query() with unicode stringsAnssi Kääriäinen
The regression was likely caused by the fix in #19606 which adjusted Oracle's unicode detection, though it seems this would have been an issue in some configurations even before.
2013-02-23Fixed empty strings + to_field regression on OracleAnssi Kääriäinen
Querying the reverse side of nullable to_field relation, where both sides can contain null values resulted in incorrect results. The reason was not detecting '' as NULL. Refs #17541
2013-02-21Factored code and added a missing docstring.Aymeric Augustin
2013-02-21Fixed #19870 -- Regression in select_related in inheritance casesAnssi Kääriäinen
There was a regression in case two models inherited the same parent, and one contained a foreign key to other. When select_related travelled the foreign key the other model reused the parent join made by the first model. This was likely caused by Query.join_parent_model() addition in commit 68985db48212c701a3d975636123a5d79bdc006f. Thanks to Trac alias loic84 for report & tests.
2013-02-20Cleaned up join promotion in query.combine() with ORAnssi Kääriäinen
Refs #19849
2013-02-20Removed join() promote kwargAnssi Kääriäinen
The join promote=True was over-aggressive in select_related handling. After that was removed, the only other user was query.combine(). That use case is very easy to handle locally, so there is no more need for the join(promote=True) flag. Refs #19849.
2013-02-20Refactored negated IS NULL handlingAnssi Kääriäinen
This one cleaned up add_filter() negated filter generation. As a side effect split_exclude() was cleaned up, too. Refs #19849
2013-02-20Added a db_constraint option to ForeignKeys.Alex Gaynor
This controls whether or not a database level cosntraint is created. This is useful in a few specialized circumstances, but in general should not be used!
2013-02-19This function is unused and should have been removed a few releases ago.Alex Gaynor
2013-02-19Ensured a connection is established when checking the database version.Aymeric Augustin
Fixed a test broken by 21765c0a. Refs #18135.
2013-02-19Implemented Oracle version as a cached property.Aymeric Augustin
2013-02-19Fixed #19837 -- Refactored split_exclude() join generationAnssi Kääriäinen
The refactoring mainly concentrates on making sure the inner and outer query agree about the split position. The split position is where the multijoin happens, and thus the split position also determines the columns used in the "WHERE col1 IN (SELECT col2 from ...)" condition. This commit fixes a regression caused by #10790 and commit 69597e5bcc89aadafd1b76abf7efab30ee0b8b1a. The regression was caused by wrong cols in the split position.
2013-02-18Added required methods in BaseDatabaseWrapper.Aymeric Augustin

2013-02-18Implemented PostgreSQL version as a cached property.Aymeric Augustin
2013-02-18Removed duplicate caching of mysql_version.Aymeric Augustin
The manual caching in self.server_version and the cached_property decorator are redundant.
2013-02-18Fixed #15119 -- Stopped pinging the MySQL server.Aymeric Augustin
2013-02-18Simplified MySQL version checking.Aymeric Augustin
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. Reverts 4423757c0c50afbe2470434778c8d5e5b4a70925. Closes #18135.
2013-02-18Factored out common code in database backends.Aymeric Augustin
2013-02-18Removed an unecessary function.Aymeric Augustin
It was introduced by the refactoring in 5a4e63e6 and made redundant by the refactoring in 18934677.
2013-02-16Fixed #17260 -- Added time zone aware aggregation and lookups.Aymeric Augustin
Thanks Carl Meyer for the review.

2013-02-13Removed try-except in django.db.close_connection()Anssi Kääriäinen
The reason was that the except clause needed to remove a connection from the django.db.connections dict, but other parts of Django do not expect this to happen. In addition the except clause was silently swallowing the exception messages. Refs #19707, special thanks to Carl Meyer for pointing out that this approach should be taken.
2013-02-11Added a check in the creation of IS NULL clauses.Aymeric Augustin
value_annotation isn't very well defined. Before this change, setting it to datetime.datetime could silently reverse the behavior of isnull lookups. This commit doesn't have any consequences on the current code. It's just a safeguard for future ORM hackers.
2013-02-10Made Query.clear_ordering force_empty arg mandatoryAnssi Kääriäinen
Previously it was possible to call clear_ordering without the force_empty argument. The result was that the query was still ordered by model's meta ordering if that was defined. By making the arg mandatory it will be easier to spot possible errors caused by assuming clear_ordering will remove all ordering. Thanks to Dylan Klomparens for the suggestion. Refs #19720.
2013-02-10Fixed #19720 -- Oracle ordering related delete regressionAnssi Kääriäinen
When a query had a complex where condition (a condition targeting more than the base table) a subquery was used for deletion. However, the query had default ordering from the model's meta and Oracle doesn't work with ordered subqueries. The regression was caused by fast-path deletion code introduced in 1cd6e04cd4f768bcd4385b75de433d497d938f82 for fixing #18676. Thanks to Dylan Klomparens for the report.
2013-02-10Fixed #19638 -- Skipped tx support testing for some DBsAnssi Kääriäinen
PostgreSQL and Oracle always support transactions, so the create table and rollback test is non-necessary on those DBs. Thanks to shai for report.
