Thanks to josh.oosterman for the report and patch.

Thanks zsiciarz for the draft patch.

At least Oracle needs parentheses in negated where conditions, even if
there is only single condition negated. Fixed this by reverting to old
logic in that part of as_sql() and adding a comment about this.

I did not investigate why the parentheses are needed. The original
offending commit was bd283aa8.

When the postgresql_psycopg2 backend was used with DB-level autocommit
mode enabled, after entering transaction management and then leaving
it, the isolation level was never set back to autocommit mode.

Thanks brodie for report and working on this issue.

 - backends: supports_transactions()
 - select_for_update tests

Made sure the WhereNode.as_sql() handles various EmptyResultSet and
FullResultSet conditions correctly. Also, got rid of the FullResultSet
exception class. It is now represented by '', [] return value in the
as_sql() methods.

Thanks to harm for the report and comments.

Thanks Claude Paroz for the draft patch.

Thanks xbito for the draft patch.

This keyword was already deprecated in the code (supported for

Thanks to Josh Smeaton for report & patch.

When a FileField value has been saved, a new validation should not
regenerate a new filename when checking the length. Refs #9893.

This commit tackles a couple of issues. First, in certain cases there
were some mixups if field.attname or field.name should be deferred.
Field.attname is now always used.

Another issue tackled is a case where field is both deferred by
.only(), and selected by select_related. This case is now an error.

A lot of thanks to koniiiik (Michal Petrucha) for the patch, and
to Andrei Antoukh for review.

Thanks Rob Golding for helping on the patch.
