Refs #20377. Fixed #24020 -- Refactored SQL compiler to use expressions 2015-01-08T19:07:54Z Anssi Kääriäinen akaariai@gmail.com 2014-12-01T07:28:01Z urn:sha1:0c7633178fa9410f102e4708cef979b873bccb76 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. Moved DatabaseCreation.data_types properties to DatabaseWrapper. 2014-12-31T13:29:17Z Tim Graham timograham@gmail.com 2014-12-29T20:14:40Z urn:sha1:93d73dac91104fd82d44b0dd4521cfa4f31e02aa refs #22340.

Thanks to Anssi for the suggestion. Fixed #24033 -- Use interval type on Oracle. 2014-12-23T10:38:32Z Marc Tamlyn marc.tamlyn@gmail.com 2014-12-21T14:36:37Z urn:sha1:5ca82e710e2f92b8c5114492205c8764918407d3 Use INTERVAL DAY(9) TO SECOND(6) for Durationfield on Oracle rather than storing as a NUMBER(19) of microseconds. There are issues with cx_Oracle which require some extra data manipulation in the database backend when constructing queries, but it handles the conversion back to timedelta objects cleanly. Thanks to Shai for the review. Fixed #2443 -- Added DurationField. 2014-12-20T18:28:29Z Marc Tamlyn marc.tamlyn@gmail.com 2014-07-24T12:57:24Z urn:sha1:57554442fe3e209c135e15dda4ea45123e579e58 A field for storing periods of time - modeled in Python by timedelta. It is stored in the native interval data type on PostgreSQL and as a bigint of microseconds on other backends. Also includes significant changes to the internals of time related maths in expressions, including the removal of DateModifierNode. Thanks to Tim and Josh in particular for reviews. Fixed postgis test database initialization 2014-12-12T19:08:07Z Claude Paroz claude@2xlibre.net 2014-12-09T14:27:20Z urn:sha1:df30ae07fc7d7500bbbe51ed3361982f645169f2 Refs #20968. Allow querying template_postgis presence without existing test database. Thanks Tim Graham for the review.
