Anssi Kääriäinen 0c7633178f Fixed #24020 -- Refactored SQL compiler to use expressions
Refactored compiler SELECT, GROUP BY and ORDER BY generation.
While there, also refactored select_related() implementation
(get_cached_row() and get_klass_info() are now gone!).

Made get_db_converters() method work on expressions instead of
internal_type. This allows the backend converters to target
specific expressions if need be.

Added query.context, this can be used to set per-query state.

Also changed the signature of database converters. They now accept
context as an argument.

Piotr Pawlaczek 41fc1c0b5e Fixed #23758 -- Allowed more than 5 levels of subqueries
Refactored bump_prefix() to avoid infinite loop and allow more than
than 5 subquires by extending the alphabet to use multi-letters.

Jon Dufresne 4468c08d70 Fixed #23968 -- Replaced list comprehension with generators and dict comprehension 2014-12-08 07:58:23 -05:00
Anssi Kääriäinen ab89414f40 Fixed #23853 -- Added Join class to replace JoinInfo
Also removed Query.join_map. This structure was used to speed up join
reuse calculation. Initial benchmarking shows that this isn't actually
needed. If there are use cases where the removal has real-world
performance implications, it should be relatively straightforward to
reintroduce it as map {alias: [Join-like objects]}.

Anssi Kääriäinen bd337184f1 Fixed #23877 -- aggregation's subquery missed target col
Aggregation over subquery produced syntactically incorrect queries in
some cases as Django didn't ensure that source expressions of the
aggregation were present in the subquery.

Anssi Kääriäinen c7fd9b242d Fixed #23875 -- cleaned up query.get_count() 2014-11-27 06:26:53 -05:00
Anssi Kääriäinen cbb5cdd155 Fixed #23867 -- removed DateQuerySet hacks
The .dates() queries were implemented by using custom Query, QuerySet,
and Compiler classes. Instead implement them by using expressions and
database converters APIs.

Anssi Kääriäinen 5c481db295 Fixed #23605 -- Fixed nested subquery regression
Added relabeled_clone() method to sql.Query to fix the problem. It
manifested itself in rare cases where at least double nested subquery's
filter condition might target non-existing alias.

Thanks to Trac alias ris for reporting the problem.

Marc Tamlyn e9103402c0 Fixed #18757, #14462, #21565 -- Reworked database-python type conversions
Complete rework of translating data values from database

Deprecation of SubfieldBase, removal of resolve_columns and
convert_values in favour of a more general converter based approach and
public API Field.from_db_value(). Now works seamlessly with aggregation,
.values() and raw queries.

Thanks to akaariai in particular for extensive advice and inspiration,
also to shaib, manfre and timograham for their reviews.
