Anssi Kääriäinen 89bf7a4525 Fixed #20528 -- regression in select_related join promotion
The join used by select_related was incorrectly INNER when the query
had an ORed filter for nullable join that was trimmed away. Fixed this
by forcing the join type to LOUTER even when a join was trimmed away
in ORed queries.

Anssi Kääriäinen d467e11785 Fixed #20507 -- SubqueryConstraint alias relabeling
The SubqueryConstraint defined relabeled_clone(), but that was never
called. Instead there is now clone() and relabel_aliases() methods for
SubqueryConstraint.

A related problem was that SubqueryConstraint didn't correctly use
quote_name_unless_alias() of the outer query. This resulted in failures
when running under PostgreSQL.

Anssi Kääriäinen 904084611d Fixed #19895 -- Second iterator over invalid qs raises errors
The fix was already in the patch for #18702, so only test added for
ticket #19895.

Anssi Kääriäinen f53059b411 Fixed qs.values() regression when used in subquery 2013-05-20 15:38:47 +03:00
Anssi Kääriäinen e17fa9e877 Fixed #20091 -- Oracle null promotion for empty strings 2013-03-26 14:19:54 +02:00
Anssi Kääriäinen 80e68ee2ff Added tests for already fixed #20101
The ticket dealt with a case where one query had .exclude() that
produced a subquery, the other query had a join to the same model that
was subqueried in the first query. This was already fixed in master, so
only test added.

Anssi Kääriäinen d3f00bd570 Refactored qs.add_q() and utils/tree.py
The sql/query.py add_q method did a lot of where/having tree hacking to
get complex queries to work correctly. The logic was refactored so that
it should be simpler to understand. The new logic should also produce
leaner WHERE conditions.

The changes cascade somewhat, as some other parts of Django (like
add_filter() and WhereNode) expect boolean trees in certain format or
they fail to work. So to fix the add_q() one must fix utils/tree.py,
some things in add_filter(), WhereNode and so on.

This commit also fixed add_filter to see negate clauses up the path.
A query like .exclude(Q(reversefk__in=a_list)) didn't work similarly to
.filter(~Q(reversefk__in=a_list)). The reason for this is that only
the immediate parent negate clauses were seen by add_filter, and thus a
tree like AND: (NOT AND: (AND: condition)) will not be handled
correctly, as there is one intermediary AND node in the tree. The
example tree is generated by .exclude(~Q(reversefk__in=a_list)).

Still, aggregation lost connectors in OR cases, and F() objects and
aggregates in same filter clause caused GROUP BY problems on some
databases.

Fixed #17600, fixed #13198, fixed #17025, fixed #17000, fixed #11293.

Anssi Kääriäinen d744c550d5 Fixed #19964 -- Removed relabel_aliases from some structs
Before there was need to have both .relabel_aliases() and .clone() for
many structs. Now there is only relabeled_clone() for those structs
where alias is the only mutable attribute.

Anssi Kääriäinen 06de130dae Fixed #12823 -- Was already fixed in master, tests added
Also added a little improvement to sql/query.py to get rid of
non-necessary IS NOT NULL check.
