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 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.

2013-02-10Fixed #19638 -- Skipped tx support testing for some DBsAnssi Kääriäinen

2012-11-27Fixed #19274 -- Made db connection creation overridable in subclassesAnssi Kääriäinen
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.

2012-07-24Fixed #18271 -- Changed stage at which TransactionTestCase flushes DB tables.Ramiro Morales
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.

2012-04-30Made get_indexes() consistent across backends.Anssi Kääriäinen
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.

2011-11-19Used symbolic constants for psycopg2 isolation levels.Aymeric Augustin
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. git-svn-id: http://code.djangoproject.com/svn/django/trunk@17112 bcc190cf-cafb-0310-a4f2-bffc1f526a37
