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 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.

commit f2dc4429a1
Author: Marc Tamlyn <marc.tamlyn@gmail.com>
Date:   Sun Jan 12 13:15:05 2014 +0000

    Reworked custom lookups docs.

    Mostly just formatting and rewording, but also replaced the example
    using ``YearExtract`` to  use an example which is unlikely to ever be
    possible directly in the ORM.

Author: Anssi Kääriäinen <akaariai@gmail.com>
Date:   Sat Jan 11 14:45:53 2014 +0200

    Altered query string customization for backends vendors

    The new way is trying to call first method 'as_' + connection.vendor.
    If that doesn't exist, then call as_sql().

    Also altered how lookup registration is done. There is now
    RegisterLookupMixin class that is used by Field, Extract and
    sql.Aggregate. This allows one to register lookups for extracts and
    aggregates in the same way lookup registration is done for fields.

Also, added a lot of comments about why join promotion is done the way
it is.

Thanks to Tim Graham for original report and testing the changes, and
for Loic Bistuer for review.
