The code that tests to see which LIKE expressions to use now runs
using non-error-wrapped cursor, so cx_Oracle exceptions need to be caught
rather than Django DatabaseErrors.
Thanks Trac user ludo for report and initial patch.
Add support for Oracle, fix an issue with the repr of RawQuerySet,
add tests and documentations. Also added a 'supports_paramstyle_pyformat'
database feature, True by default, False for SQLite.
Thanks Donald Stufft for review of documentation.
This is useful:
- to force a rollback on the exit of an atomic block without having to
raise and catch an exception;
- to prevent a rollback after handling an exception manually.
This reverts commit 64041f0e6e.
lookup.tests.LookupTests.test_regex_non_string fails under Postgres.
We should also try to rewrite the test using an existing model.
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.
Used formatted date instead of datetime object for the end of the
year range, as the datetime object loses fractions-of-seconds when
inserted into the db.
Queries can contain binary data undecodable with utf-8. In this
case, using the 'replace' errors mode when decoding seems like
an acceptable representation of the query.
Thanks Marcel Ryser for the report.
Previously, depending on the database backend or the cursor type,
you'd need to double the percent signs in the query before passing
it to cursor.execute. Now cursor.execute consistently need percent
doubling whenever params argument is not None (placeholder substitution
will happen).
Thanks Thomas Güttler for the report and Walter Doekes for his work
on the patch.
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.
Replaced them with per-database options, for proper multi-db support.
Also toned down the recommendation to tie transactions to HTTP requests.
Thanks Jeremy for sharing his experience.
Since "unless managed" now means "if database-level autocommit",
committing or rolling back doesn't have any effect.
Restored transactional integrity in a few places that relied on
automatically-started transactions with a transitory API.
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.
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.
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.
* 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 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.
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.
Change patch from https://code.djangoproject.com/ticket/5568
to work on modern Django.
Add special case for MySQL which has different syntax for DROP INDEX.
Add unit tests for the new functionality.
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.
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!
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.

Documented QuerySet.datetimes and updated QuerySet.dates.
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.
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.
The problem is the same as in #10888 which was reintroduced when
bulk_insert was added. Thanks to Jani Tiainen for report, patch and
also testing the final patch on Oracle GIS.

Previous this used Python's builtin hash() function, which has never been guarnteed to be stable across implementations (CPython/Jython/etc.) or 32/64 bitness. However, this in practice it was stable. However, with the impending release of Python 3.3 hash randomizations is enabled by default, which would mean the index name changed between program invocations.
This patch removes an unconditional float(value) conversion from db
backend default convert_values() method. This can cause problems when
aggregating over character fields for example. In addition, Oracle
and SQLite already return the bare value from their convert_values().
In the long term the converting should be done by fields, and the
fields should then call database backend specific converters when
needed. The current setup is inflexible for 3rd party fields.
Thanks to Merlijn van Deen for the original patch.
* Renamed smart_unicode to smart_text (but kept the old name under
Python 2 for backwards compatibility).
* Renamed smart_str to smart_bytes.
* Re-introduced smart_str as an alias for smart_text under Python 3
and smart_bytes under Python 2 (which is backwards compatible).
Thus smart_str always returns a str objects.
* Used the new smart_str in a few places where both Python 2 and 3
want a str.
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.
The qs.bulk_create() method did not work with large batches together
with SQLite3. This commit adds a way to split the bulk into smaller
batches. The default batch size is unlimited except for SQLite3 where
the batch size is limited to 999 SQL parameters per batch.
Thanks to everybody who participated in the discussions at Trac.
When the postgresql_psycopg2 backend was used with DB-level autocommit
mode enabled, after entering transaction management and then leaving
it, the isolation level was never set back to autocommit mode.
Thanks brodie for report and working on this issue.
In addition, removed a possibly problematic .filter() call from
backends.test_query_encoding test. It is possible the .filter could
cause collation problems on MySQL, and as it wasn't absolutely needed
for the test it seemed better to get rid of the call.
Refs #18461.
This does remove the requirement to call features.confirm() method
before checking the properties.
Thanks cdestiger and Ramiro Morales for their work on the patch.
On MySQL when checking the server version, a new connection could be
created but never closed. This could result in open connections on
server startup.
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.
Fixed#17957 -- when using Oracle and character fields, the fields
were set null = True to ease the handling of empty strings. This
caused problems when using multiple databases from different vendors,
or when the character field happened to be also a primary key.
The handling was changed so that NOT NULL is not emitted on Oracle

Fixed#18218 -- previously Django's introspection table_names() and
get_table_list() methods did not sort the output consistently. This
resulted in random order of inspected models.
This commit also removed all external usages of get_table_list().
table_names() should be used instead.
Thanks to claudep for patch and report.
corner case (boolean fields under MySQL spatial backend) had a wider scope with
potentially unintended consequences affecting the main MySQL backend and the
required changes wouldn't be appropiate at this point of the 1.4 development
cycle.

Implemented this by adding an internal hook for work that should be performed
before that point.
Also, regarding the `DatabaseCreation.set_autocommit()` method:
* Stop using it for such tasks
* Stop providing an implementation that tries to cover all the possible
idioms a third party database backend DB-API 2 driver could need to activate
autocommit. It is now left for third party backends to implement.
This can be backwards incompatible in the case of user applications that:
* Had started using this method
* Use a third a party database backend

Changed our internal representation of the PostgreSQL version from tuples to
integers as used by libpq and psycopg2. This simplifies version comparison
operations.
Also, using the associated libpq/psycopg2 API allows to remove the need for
manually issuing in-band ``SELECT version()`` SQL queries to obtain the server
version (or at least reduce its number if version of psycopg2 in use is older
than 2.0.12). Refs #10509.

NOTE: This change is backwards incompatible for some users.
If you are using a 32-bit platform, you will observe no differences as a
result of this change. However, users on 64-bit platforms may experience
some problems using the `reset` management command.
Prior to this change, 64-bit platforms would generate a 64-bit, 16 character
digest in the constraint name; for example:
ALTER TABLE `myapp_sometable` ADD CONSTRAINT `object_id_refs_id_5e8f10c132091d1e` FOREIGN KEY ...
Following this change, all platforms, regardless of word size, will
generate a 32-bit, 8 character digest in the constraint name; for example:
ALTER TABLE `myapp_sometable` ADD CONSTRAINT `object_id_refs_id_32091d1e` FOREIGN KEY ...
As a result of this change, you will not be able to use the `reset`
management command on any table created with 64-bit constraints. This
is because the the new generated name will not match the historically
generated name; as a result, the SQL constructed by the `reset` command
will be invalid.
If you need to reset an application that was created with 64-bit
constraints, you will need to manually drop the old constraint prior
to invoking `reset`.

We need to know the number of rows that are matched by an UPDATE query,
not just the number of rows that are changed. In the relatively unlikely
event that somebody was using Django's cursor proxy and relying on the
previous behaviour, well, that isn't the case any longer. We need to
this version.
Thanks to Daniel Tang for pointing out the solution here.

We now pass numbers used in data queries as actualy numbers (integers) to the
database backends, rather than string forms. This is easier for some of the
less flexible backeds.
Based on a patch from Leo Soto and Ramiro Morales.

Affects the postgresql_psycopg2 backend only. We now don't use the
"RETURNING" syntax in SQL INSERT statements unless it's required by the
autocommit behaviour. This fixes an edge-case that could cause crashes
with earlier PostgreSQL versions, but the broader problem remains to be
fixed (which is #10509).
Fixed#10467. Refs #10509.

In order to report more comphrehensible tracebacks, remove the super()
constructor call, since passing args to object.__init__ ends badly. So some
subclassing possibilities are now removed, but it's the "dummy" backend, so
we can make some compromises.

I introduced a bad regression in r10029, forgetting to check that some
syntax was supported. For now, you can't use autocommit=True with 8.1
and earlier (it's still available for later versions). I'll fix the
broader issue later and re-enable it for those versions, but I want to
get the SQL regression for the default path out of the code right now.

Ensure to read the documentation before blindly enabling this: requires some
code audits first, but might well be worth it for busy sites.

This is backwards-compatible but will likely break third-party database backends. Specific API changes are:
* BaseDatabaseWrapper.__init__() now takes a settings_dict instead of a settings module. It's called settings_dict to disambiguate, and for easy grepability. This should be a dictionary containing DATABASE_NAME, etc.
* BaseDatabaseWrapper has a settings_dict attribute instead of an options attribute. BaseDatabaseWrapper.options is now BaseDatabaseWrapper['DATABASE_OPTIONS']
* BaseDatabaseWrapper._cursor() no longer takes a settings argument.
* BaseDatabaseClient.__init__() now takes a connection argument (a DatabaseWrapper instance) instead of no arguments.

This allows a model to be defined which is not subject to database table

database views.

This change may be slightly backwards incompatible, if existing tests need to test transactional behavior, or if they rely on invalid assumptions or a specific test case ordering. For the first case, django.test.TransactionTestCase should be used. TransactionTestCase is also a quick fix to get around test case errors revealed by the new rollback approach, but a better long-term fix is to correct the test case. See the testing doc for full details.

Columns are NULL by default, so we only need to use "NOT NULL" when we want
