* Fixed #470 -- Added support for database defaults on fields.Ian Foote2023-05-1210-18/+155
| | | | | | | | Special thanks to Hannes Ljungberg for finding multiple implementation gaps. Thanks also to Simon Charette, Adam Johnson, and Mariusz Felisiak for reviews.
* Fixed #34553 -- Fixed improper % escaping of literal in constraints.Simon Charette2023-05-103-5/+1
| | | | | | | | | | | | | | | | | | | | | | | | | Proper escaping of % in string literals used when defining constaints was attempted (a8b3f96f6) by overriding quote_value of Postgres and Oracle schema editor. The same approach was used when adding support for constraints to the MySQL/MariaDB backend (1fc2c70). Later on it was discovered that this approach was not appropriate and that a preferable one was to pass params=None when executing the constraint creation DDL to avoid any form of interpolation in the first place (42e8cf47). When the second patch was applied the corrective of the first were not removed which caused % literals to be unnecessary doubled. This flew under the radar because the existings test were crafted in a way that consecutive %% didn't catch regressions. This commit introduces an extra test for __exact lookups which highlights more adequately % doubling problems but also adjust a previous __endswith test to cover % doubling problems (%\% -> %%\%%). Thanks Thomas Kolar for the report. Refs #32369, #30408, #30593.

* Fixed #34523 -- Fixed TransactionManagementError in ↵Mariusz Felisiak2023-05-031-3/+0
| | | | | | | | | | | | | | QuerySet.update_or_create() with MyISAM storage engine. QuerySet.update_or_create() uses nested atomic to handle possible integrity errors taking savepoints as way to mark back the connection as usable. Savepoints are not returned when uses_savepoints/can_release_savepoints feature flags are set to False. As a consequence, QuerySet.update_or_create() assumed the outer atomic block is tainted and raised TransactionManagementError. This commit partly reverts 331a460f8f2e4f447b68fba491464b68c9b21fd1. Thanks gatello-s for the report.

| | | | | | | obj_description(object oid) without a catalog name is deprecated since there is no guarantee that OIDs are unique across different system catalogs. Thanks Tim Graham for the report.
* Fixed #34176 -- Fixed grouping by ambiguous aliases.Simon Charette2023-01-092-2/+2
| | | | | | | | | | | | | | | Regression in b7b28c7c189615543218e81319473888bc46d831. Refs #31377. Thanks Shai Berger for the report and reviews. test_aggregation_subquery_annotation_values_collision() has been updated as queries that are explicitly grouped by a subquery should always be grouped by it and not its outer columns even if its alias collides with referenced table columns. This was not possible to accomplish at the time 10866a10 landed because we didn't have compiler level handling of colliding aliases.
