2015-02-20[1.8.x] Update converters to take a consistent set of parameters.Marc Tamlyn
As suggested by Anssi. This has the slightly strange side effect of passing the expression to Expression.convert_value has the expression passed back to it, but it allows more complex patterns of expressions. Backport of 32d4db66b9 from master
2015-02-17[1.8.x] Refs #24324 -- Fixed UnicodeEncodeError in SQLite backend while testing.Tim Graham
If 'name' contained non-ASCII characters, the comparison raised a UnicodeEncodeError on Python 2. Backport of 63c5c9870129f6b81358c1ed7ed2392bbc46f77d from master

2015-01-10Introspected alternate SQLite FK definitionsClaude Paroz
2015-01-08Fixed #24020 -- Refactored SQL compiler to use expressionsAnssi Kääriäinen
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.
2015-01-06Fixed #12663 -- Formalized the Model._meta API for retrieving fields.Daniel Pyrathon

2014-12-20Fixed #2443 -- Added DurationField.Marc Tamlyn
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.

2014-09-03Fixed #18757, #14462, #21565 -- Reworked database-python type conversionsMarc Tamlyn
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.

2014-04-18Fixed #22397 -- Issues removing M2M field with explicit through modelAndrew Gorcester
Changed the migration autodetector to remove models last so that FK and M2M fields will not be left as dangling references. Added a check in the migration state renderer to error out in the presence of dangling references instead of leaving them as strings. Fixed a bug in the sqlite backend to handle the deletion of M2M fields with "through" models properly (i.e., do nothing successfully). Thanks to melinath for report, loic for tests and andrewgodwin and charettes for assistance with architecture.

This reverts commit 00e3b9a2a992ee0b7288eeeb03e7cbd52ebc6dce. It's causing a regression when tested with the proxy_model_inheritance tests.
