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.

2013-09-05[1.6.x] Fixed #21035 -- Changed docs to treat the acronym SQL phonetically.Eric Boersma

Thanks Marc Tamlyn and Tim Graham for the review. Backport of 7442eb1a24 from master.
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.
2013-06-27Fixed #20571 -- Added an API to control connection.needs_rollback.Aymeric Augustin
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.
2013-06-01Fixed #20543 - Typo in db model fields docs.Tim Graham
Thanks i.amber.jain@ for the report.

2013-05-19Changed API to disable ATOMIC_REQUESTS per view.Aymeric Augustin
A decorator is easier to apply to CBVs. Backwards compatibility isn't an issue here, except for people running on a recent clone of master. Fixed a few minor problems in the transactions docs while I was there.

Thanks Florian for reporting this omission.
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.

2013-03-13Proof-read and adjusted the transactions docs.Aymeric Augustin
2013-03-13Made atomic usable when autocommit is off.Aymeric Augustin
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.

2013-03-11Updated the documentation for savepoints.Aymeric Augustin
Apparently django.db.transaction used to be an object.
2013-03-11Deprecated TransactionMiddleware and TRANSACTIONS_MANAGED.Aymeric Augustin
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.
2013-03-11Added some assertions to enforce the atomicity of atomic.Aymeric Augustin
2013-03-11Implemented an 'atomic' decorator and context manager.Aymeric Augustin
Currently it only works in autocommit mode. Based on @xact by Christophe Pettus.
2013-03-11Added support for savepoints in SQLite.Aymeric Augustin
Technically speaking they aren't usable yet.
2013-03-11Enabled database-level autocommit for all backends.Aymeric Augustin
This is mostly a documentation change. It has the same backwards-incompatibility consequences as those described for PostgreSQL in a previous commit.
