Thanks Simon Charette for reviews.
2020-07-28Fixed #31836 -- Dropped support for JSONField __contains and __contained_by ↵Mariusz Felisiak
lookups on SQLite. The current implementation works only for basic examples without supporting nested structures and doesn't follow "the general principle that the contained object must match the containing object as to structure and data contents, possibly after discarding some non-matching array elements or object key/value pairs from the containing object".
2020-07-22Fixed #31765 -- Disabled bundled SQLite renaming atomic references on macOS ↵Tom Forbes
10.15.

2020-05-08Fixed #12990, Refs #27694 -- Added JSONField model field.sage

2020-04-21Fixed #31479 -- Added support to reset sequences on SQLite.Jon Dufresne
2020-04-21Refs #30591 -- Adjusted table rebuild for non-pk relationship on SQLite.Simon Charette
The existing code was only accounting for primary key changes and not all unique key fields that can be referenced.
2020-04-21Fixed #31064 -- Recreated auto-created many-to-many tables on primary key ↵Simon Charette
data type change on SQLite. Both local and remote auto-created many-to-many relationships were affected.
2020-04-20Stopped rebuilding referenced tables multiple times on SQLite alterations.Simon Charette
2020-04-17Fixed #31473 -- Made sql_flush() use RESTART IDENTITY to reset sequences on ↵Jon Dufresne
PostgreSQL. The sql_flush() positional argument sequences is replaced by the boolean keyword-only argument reset_sequences. This ensures that the old function signature can't be used by mistake when upgrading Django. When the new argument is True, the sequences of the truncated tables will reset. Using a single boolean value, rather than a list, allows making a binary yes/no choice as to whether to reset all sequences rather than a working on a completely different set.
2020-04-14Fixed #29501 -- Allowed dbshell to pass options to underlying tool.Adam Johnson
2020-04-06Fixed #31030 -- Registered SQLite functions as deterministic on Python 3.8+.Sergey Fedoseev
2020-03-25Fixed #31396 -- Added binary XOR operator to F expressions.Hannes Ljungberg
2020-03-18Fixed #31376 -- Optimized nulls ordering when possible on SQLite and MySQL.Simon Charette
Both backends order NULLs first on ascending ordering and last on descending ordering which makes ORDER BY IS (NOT)? NULL wasteful when asc(nulls_first) and desc(nulls_last) are used since it prevents indice usage.
2020-02-18Fixed #31228 -- Reallowed aggregates to be used with multiple expressions ↵Taoup
and no DISTINCT on SQLite. Regression in bc05547cd8c1dd511c6b6a6c873a1bc63417b111. Thanks Andy Terra for the report.
2020-02-06Fixed #31233 -- Closed database connections and cursors after use.Jon Dufresne
