5d8342f321 Proof-read and adjusted the transactions docs. 2013-03-13 15:17:41 +01:00

83a416f5e7 Made atomic usable when autocommit is off. 
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.

ac37ed21b3 Deprecated TransactionMiddleware and TRANSACTIONS_MANAGED. 
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.

d7bc4fbc94 Implemented an 'atomic' decorator and context manager. 
Currently it only works in autocommit mode.

Based on @xact by Christophe Pettus.

5e27debc5c Enabled database-level autocommit for all backends. 
This is mostly a documentation change.

It has the same backwards-incompatibility consequences as those
described for PostgreSQL in a previous commit.

1b646e656e Fixed #19384 -- Documented the behavior of custom managers on abstract models. 
This documents the behavior introduced by cc337a74, which is BACKWARDS
INCOMPATIBLE for any attempt to invoke a method on a manager using the
abstract class as the calling class (e.g., AbstractBase.objects.do_something())

70fac984c8 Fixed format-o in docs/topics/db/queries.txt 
It appears that our infamous villain, Significant Whitespace,
has struck again.

In this episode, little Timmy finds himself trapped in a
code well.  He need not despair, however, as Indentation Man
has heard his cries for help and sprung into action.

With his feline helper, Octocat, at his side, Indentation Man
races to the scene, flings open a web-based code editor, and with
terrific aplomb, frees Timmy to be the documentation he always
wanted to be.

Once again Goodness has prevailed.  In the fight for readable
documentation, no stray whitespace will ever be able to
withstand the str.strip()ing nature of....INDENTATION MAN.
