2013-10-07[1.6.x] Fixed #21235 -- Disabled savepoints for old versions of SQLite.Aymeric Augustin
Thanks Ramiro for the report. Backport of 91547772 from master.
2013-09-30Fixed #21134 -- Prevented queries in broken transactions.Aymeric Augustin
Backport of 728548e4 from master. Squashed commit of the following: commit 63ddb271a44df389b2c302e421fc17b7f0529755 Author: Aymeric Augustin <aymeric.augustin@m4x.org> Date: Sun Sep 29 22:51:00 2013 +0200 Clarified interactions between atomic and exceptions. commit 2899ec299228217c876ba3aa4024e523a41c8504 Author: Aymeric Augustin <aymeric.augustin@m4x.org> Date: Sun Sep 22 22:45:32 2013 +0200 Fixed TransactionManagementError in tests. Previous commit introduced an additional check to prevent running queries in transactions that will be rolled back, which triggered a few failures in the tests. In practice using transaction.atomic instead of the low-level savepoint APIs was enough to fix the problems. commit 4a639b059ea80aeb78f7f160a7d4b9f609b9c238 Author: Aymeric Augustin <aymeric.augustin@m4x.org> Date: Tue Sep 24 22:24:17 2013 +0200 Allowed nesting constraint_checks_disabled inside atomic. Since MySQL handles transactions loosely, this isn't a problem. commit 2a4ab1cb6e83391ff7e25d08479e230ca564bfef Author: Aymeric Augustin <aymeric.augustin@m4x.org> Date: Sat Sep 21 18:43:12 2013 +0200 Prevented running queries in transactions that will be rolled back. This avoids a counter-intuitive behavior in an edge case on databases with non-atomic transaction semantics. It prevents using savepoint_rollback() inside an atomic block without calling set_rollback(False) first, which is backwards-incompatible in tests. Refs #21134. commit 8e3db393853c7ac64a445b66e57f3620a3fde7b0 Author: Aymeric Augustin <aymeric.augustin@m4x.org> Date: Sun Sep 22 22:14:17 2013 +0200 Replaced manual savepoints by atomic blocks. This ensures the rollback flag is handled consistently in internal APIs.

2013-06-28Support 'pyformat' style parameters in raw queries, Refs #10070Shai Berger
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.

2013-06-11Revert "Fixed #20462 - Fixed sqlite regex lookups for null values and ↵Tim Graham
non-string fields." This reverts commit 64041f0e6e7a773574d7cde978d16305200004ea. lookup.tests.LookupTests.test_regex_non_string fails under Postgres. We should also try to rewrite the test using an existing model.
2013-06-11Fixed #20462 - Fixed sqlite regex lookups for null values and non-string fields.Axel Haustant
2013-06-10Added a stealth option to flush to allow cascades.Aymeric Augustin
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.
2013-03-23Fixed #9055 -- Standardized behaviour of parameter escaping in db cursorsClaude Paroz
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.
2013-03-11Implemented an 'atomic' decorator and context manager.Aymeric Augustin

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.

2013-01-12Return namedtuple from get_table_descriptionClaude Paroz
We don't make use of it currently to not break third-party db backends.
2013-01-11Fixed #19360 -- Raised an explicit exception for aggregates on date/time ↵Nick Sandford
fields in sqlite3 Thanks lsaffre for the report and Chris Medrela for the initial patch.
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.
2012-11-24Fixed #19351 -- SQLite bulk_insert of more than 500 single-field objsAnssi Kääriäinen
2012-11-24Fixed SQLite's collapsing of same-valued instances in bulk_createAnssi Kääriäinen
SQLite used INSERT INTO tbl SELECT %s UNION SELECT %s, the problem was that there should have been UNION ALL instead of UNION. Refs #19351
2012-10-22Fixed #19162 -- Wrong indentation.Jan Bednařík
2012-09-07Removed many uses of bare "except:", which were either going to a) silence ↵Alex Gaynor
real issues, or b) were impossible to hit.
2012-08-30Made get_table_description also return the size of char fields on SQLiteClaude Paroz
2012-08-18[py3] Ported django.utils.safestring.Aymeric Augustin
Backwards compatibility aliases were created under Python 2.
2012-08-12[py3] Always convert values from sqlite3 to unicode stringsClaude Paroz
Thanks Aymeric Augustin for the review.
2012-08-08[py3] Replaced raw_input by inputClaude Paroz
The six addition has been borrowed from: https://bitbucket.org/gutworth/six/changeset/733ef740
2012-08-03Replaced some byte strings by str() callsClaude Paroz
This is a useful trick when Python 2 awaits byte strings and Python 3 Unicode (regular) strings.
2012-07-22[py3] Replaced unicode/str by six.text_type/bytes.Aymeric Augustin
2012-07-22[py3] Exception aren't iterable in Python 3.Aymeric Augustin
2012-07-22[py3] Used six.reraise wherever necessary.Aymeric Augustin
2012-07-17Fixed #17788 -- Added batch_size argument to qs.bulk_create()Anssi Kääriäinen
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.
2012-07-10Fixed #18602 -- Improved error message when database NAME is missingClaude Paroz
Thanks Kristian Glass for the report.
2012-06-09Fixed #17760 -- Implemented callable database features as cached propertiesClaude Paroz
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.
2012-06-07Fixed #18269 -- Applied unicode_literals for Python 3 compatibility.Claude Paroz
Thanks Vinay Sajip for the support of his django3 branch and Jannis Leidel for the review.
2012-05-19Marked bytestrings with b prefix. Refs #18269Claude Paroz
This is a preparation for unicode literals general usage in Django (Python 3 compatibility).
2012-04-30Replaced print statement by print function (forward compatibility syntax).Claude Paroz
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.
2012-04-29Fixed #18013 -- Use the new 'as' syntax for exceptions.Claude Paroz
Thanks Clueless for the initial patch. Note that unittest has been purposely left out (external package only used by Python 2.6).
2012-04-29Made table_names() output sorted.Anssi Kääriäinen
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.
2012-03-13Fixed #16329 -- Fixed detection of transaction-handling capabilities when ↵Ramiro Morales
all test databases are sqlite3, in-memory. Thanks canassa for the report and agriffis (#17762) and lrekucki (in #17758) for their contribution to the fix. git-svn-id: http://code.djangoproject.com/svn/django/trunk@17702 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2012-02-27Fixed #17755 -- Ensured datetime objects that bypass the model layer (for ↵Aymeric Augustin
instance, in raw SQL queries) are converted to UTC before sending them to the database when time zone support is enabled. Thanks Anssi for the report. git-svn-id: http://code.djangoproject.com/svn/django/trunk@17596 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2012-02-11Removed code duplicated in SQLite3 and SpatiaLite GeoDjango DB backends.Ramiro Morales
Moved it to an auxiliary method in the SQLite3 backend cursor class. Did this to reduce the chances of us forgetting to port changes in DB connection setup process from the former to the latter one like it happened e.g. in r17205.
