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

ffe41591e7 Updated the documentation for savepoints.

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.

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.

This rewrites the entire example to use the same DB names throughout,

missing import of the random module for choosing a read slave is
included in the example now.

7deb25b8dd Fixed #7596. Added Model.objects.bulk_create, and make use of it in several places. This provides a performance benefit when inserting multiple objects. THanks to Russ for the review, and Simon Meers for the MySQl implementation.

932b1b8d6d Converted links to external topics so they use intersphinx extension markup. 
This allows to make these links more resilent to changes in the target URLs.
Thanks Jannis for the report and Aymeric Augustin for the patch.

Fixes #16586.
