2021-02-09[3.2.x] Fixed #32425 -- Fixed adding nullable field with default on MySQL.Jordan Bae
Thanks Simon Charette for the review. Backport of d4ac23bee1c84d8e4610350202ac068fc90f38c0 from master
2021-01-26[3.2.x] Fixed #32369 -- Fixed adding check constraints with pattern lookups ↵Simon Charette
and expressions as rhs. This disables interpolation of constraint creation statements. Since Constraint.create_sql interpolates its parameters instead of deferring this responsibility to the backend connection it must disable connection level parameters interpolation. Backport of 42e8cf47c7ee2db238bf91197ea398126c546741 from master

2020-12-11Refs #32178 -- Changed BaseDatabaseFeatures.django_test_expected_failures to ↵Hasan Ramezani
set().
2020-12-10Fixed #32178 -- Allowed database backends to skip tests and mark expected ↵Hasan Ramezani
failures. Co-authored-by: Tim Graham <timograham@gmail.com>
2020-12-02Fixed #32179 -- Added JSONObject database function.Artur Beltsov
2020-11-11Fixed #31762 -- Made reloading the database for tests use the base manager.Hasan Ramezani

that don't affect the schema.
2020-10-14Fixed #31640 -- Made Trunc() truncate datetimes to Date/TimeField in a ↵David-Wobrock
specific timezone.
2020-10-02Fixed #32060 -- Added Random database function.Nick Pope
2020-09-23Fixed #32012 -- Made test database creation sync apps models when migrations ↵Mariusz Felisiak
are disabled. Thanks Jaap Roes for the report.
2020-09-21Fixed #31777 -- Added support for database collations to Char/TextFields.Tom Carrick
Thanks Simon Charette and Mariusz Felisiak for reviews.
2020-09-18Refs #21181 -- Corrected DatabaseFeatures.test_collations for Swedish collation.Tom Carrick
Previously, backends used different keys "swedish-ci" or "swedish_ci".
2020-09-04Fixed #27417 -- Made RenameField operation a noop for field name case ↵Mariusz Felisiak
changes on Oracle. Field names are always uppercased in the Oracle backend. Changing case should be a noop to avoid database errors: "ORA-00957: duplicate column name".
2020-08-28Fixed #31956 -- Fixed crash of ordering by JSONField with a custom decoder ↵Mariusz Felisiak
on PostgreSQL. Thanks Marc Debureaux for the report. Thanks Simon Charette, Nick Pope, and Adam Johnson for reviews.
2020-08-14Fixed #31826 -- Made AlterField operation a noop when adding db_column.Iuri de Silvio
AlterField operation with adding a db_column is a noop if the column name is not changed.
2020-08-13Fixed #31825 -- Made RenameField operation a noop for fields with db_column.Iuri de Silvio

Thanks Simon Charette for reviews.
2020-07-30Bumped minimum isort version to 5.1.0.David Smith
Fixed inner imports per isort 5. isort 5.0.0 to 5.1.0 was unstable.
2020-07-30Refs #31829 -- Added ↵Tim Graham
DatabaseFeatures.json_key_contains_list_matching_requires_list. CockroachDB's behavior matches PostgreSQL.
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".
2020-07-20Fixed #17653 -- Allowed using zero as AutoFields value on MySQL if ↵Mariusz Felisiak
NO_AUTO_VALUE_ON_ZERO SQL mode is enabled.
2020-07-02Fixed #31758 -- Removed unneeded BytesToCharFieldConversionMixin.Sergey Fedoseev
Bug was fixed in mysqlclient 1.3.13.
2020-06-30Fixed #28925 -- Fixed durations-only expressions crash on SQLite and MySQL.Sergey Fedoseev
This removes also unused DatabaseOperations.date_interval_sql().
2020-06-24Fixed #31735 -- Fixed migrations crash on namespaced inline FK addition on ↵Simon Charette
PostgreSQL. The namespace of the constraint must be included when making the constraint immediate. Regression in 22ce5d0031bd795ade081394043833e82046016c. Thanks Rodrigo Estevao for the report.
2020-06-16Fixed #31702 -- Added support for PostgreSQL opclasses in UniqueConstraint.Hannes Ljungberg
2020-06-04Fixed #30913 -- Added support for covering indexes on PostgreSQL 11+.Hannes Ljungberg
2020-06-04Refs #31630 -- Added CharField and IntegerField to ↵Tim Graham
DatabaseFeatures.introspected_field_types. CockroachDB introspects CharField as TextField and IntegerField as BigIntegerField.
2020-06-04Refs #31630 -- Removed DatabaseFeatures.can_introspect_autofield.Tim Graham
2020-06-04Fixed #31630 -- Replaced introspection features with ↵Hasan Ramezani
DatabaseFeatures.introspected_field_types.
2020-05-21Fixed #30375 -- Added FOR NO KEY UPDATE support to ↵Manuel Weitzman
QuerySet.select_for_update() on PostgreSQL.
2020-05-18Refs #12990 -- Added DatabaseFeatures.has_json_operators.Tim Graham
CockroachDB also has them.
2020-05-14Fixed #31584 -- Fixed crash when chaining values()/values_list() after ↵Mariusz Felisiak
Exists() annotation and aggregation on Oracle. Oracle requires the EXISTS expression to be wrapped in a CASE WHEN in the GROUP BY clause. Regression in efa1908f662c19038a944129c81462485c4a9fe8.
2020-05-08Fixed #12990, Refs #27694 -- Added JSONField model field.sage
Thanks to Adam Johnson, Carlton Gibson, Mariusz Felisiak, and Raphael Michel for mentoring this Google Summer of Code 2019 project and everyone else who helped with the patch. Special thanks to Mads Jensen, Nick Pope, and Simon Charette for extensive reviews. Co-authored-by: Mariusz Felisiak <felisiak.mariusz@gmail.com>
2020-05-06Fixed a/an typos in "SQL" usage.Adam Johnson
2020-04-30Fixed #20581 -- Added support for deferrable unique constraints.Ian Foote
2020-04-24Refs #30913 -- Added BaseDatabaseSchemaEditor._index_condition_sql().Hannes Ljungberg
2020-04-23Fixed #29224 -- Fixed removing index_together indexes if exists ↵David Wobrock
unique_together constraint on the same fields.
2020-04-20Fixed #31477 -- Removed "using" argument from ↵Jon Dufresne
DatabaseOperations.execute_sql_flush().
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.
2020-04-17Refs #26552 -- Made reloading the database for tests check only loaded ↵Mariusz Felisiak
tables constraints.
2020-04-14Fixed #29501 -- Allowed dbshell to pass options to underlying tool.Adam Johnson
2020-04-02Refs #31051 -- Optimized serialize_db_to_string() by avoiding creation of ↵Matthijs Kooijman
models list.
2020-04-02Refs #31051 -- Fixed reloading the database with circular related objects ↵Matthijs Kooijman
and natural keys for tests. Made deserialize_db_from_string() do not sort dependencies. deserialize_db_from_string() doesn't use natural keys, so there is no need to sort dependencies in serialize_db_to_string(). Moreover, sorting models cause issues for circular dependencies.
