Aymeric Augustin d63e55039d Reordered methods in database wrappers.
* Grouped related methods together -- with banner comments :/
* Described which methods are intended to be implemented in backends.
* Added docstrings.
* Used the same order in all wrappers.

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.

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.

Anssi Kääriäinen ce094e570e Fixed Oracle regression in last_executed_query() with unicode strings
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.

Alex Gaynor b55cde054e Added a db_constraint option to ForeignKeys.
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!

Aymeric Augustin 282b2f40cd Fixed #15119 -- Stopped pinging the MySQL server. 2013-02-18 22:12:19 +01:00
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.

Closes #18135.

2012-12-18 09:56:30 +01:00
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 905ea9619b Made sure global settings are changed in test db creation
There was an assumption that changing connection.settings_dict changed
also the settings.DATABASES values. This assumption is now gone.
2012-11-27 19:47:20 +02:00
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.
