Checked the following locations: * Model.save(): If there are parents involved, take the safe way and use transactions since this should be an all or nothing operation. If the model has no parents: * Signals are executed before and after the previous existing transaction -- they were never been part of the transaction. * if `force_insert` is set then only one query is executed -> atomic by definition and no transaction needed. * same applies to `force_update`. * If a primary key is set and no `force_*` is set Django will try an UPDATE and if that returns zero rows it tries an INSERT. The first case is completly save (single query). In the second case a transaction should not produce different results since the update query is basically a no-op then (might miss something though). * QuerySet.update(): no signals issued, single query -> no transaction needed. * Model/Collector.delete(): This one is fun due to the fact that is does many things at once. Most importantly though: It does send signals as part of the transaction, so for maximum backwards compatibility we need to be conservative. To ensure maximum compatibility the transaction here is removed only if the following holds true: * A single instance is being deleted. * There are no signal handlers attached to that instance. * There are no deletions/updates to cascade. * There are no parents which also need deletion.

* Fixed #24921 -- set_autocommit(False) + ORM queries.Aymeric Augustin2015-09-211-2/+15
| | | | | | | | | | | | | This commits lifts the restriction that the outermost atomic block must be declared with savepoint=False. This restriction was overly cautious. The logic that makes it safe not to create savepoints for inner blocks also applies to the outermost block when autocommit is disabled and a transaction is already active. This makes it possible to use the ORM after set_autocommit(False). Previously it didn't work because ORM write operations are protected with atomic(savepoint=False).

| | | | | Refs #15802 -- Reverted #7c657b24 as BaseDatabaseWrapper.close() now has a proper "finally" clause that may need to preserve self.connection.

* Ensure cursors are closed when no longer needed.Michael Manfre2014-02-021-6/+7
| | | | | | This commit touchs various parts of the code base and test framework. Any found usage of opening a cursor for the sake of initializing a connection has been replaced with 'ensure_connection()'.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* Translated a test to English for consistency.Aymeric Augustin2013-09-221-2/+2

* Partial revert of 165f44aa.Aymeric Augustin2013-09-221-82/+97
| | | | | | That commit didn't always improve readability. See discussion on django-developers for details.
* Combine consecutive with statementsClaude Paroz2013-08-161-97/+82
| | | | Python 2.7 allows to combine several 'with' instructions.
* Removed most of absolute_import importsClaude Paroz2013-07-291-1/+1
| | | | | Should be unneeded with Python 2.7 and up. Added some unicode_literals along the way.

|
* Fixed #20571 -- Added an API to control connection.needs_rollback.Aymeric Augustin2013-06-271-2/+24
| | | | | | | 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.
* Defined available_apps in relevant tests.Aymeric Augustin2013-06-101-0/+16
| | | | Fixed #20483.
* Moved IgnorePendingDeprecationWarningsMixin in django.test.utils.Aymeric Augustin2013-05-181-13/+1
| | | | This mixin is useful whenever deprecating a large part of Django.
* Made atomic usable when autocommit is off.Aymeric Augustin2013-03-131-11/+19
| | | | | | | | | | | | | | | | 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.
* Fixed #20028 -- Made atomic usable on callable instances.Aymeric Augustin2013-03-121-0/+11
