Co-Authored-By: Nick Pope <nick@nickpope.me.uk>
2021-12-22Refs #32355 -- Bumped required psycopg2 version to 2.8.4.Mariusz Felisiak
psycopg2 2.8.4 is the first release to support Python 3.8.
2021-12-22Refs #33355 -- Optimized Trunc() on SQLite by using f-strings.Adam Johnson
Co-Authored-By: Nick Pope <nick@nickpope.me.uk>
2021-12-22Refs #33355 -- Added missing tests for database functions and expression on ↵Adam Johnson
null values.
2021-12-21Fixed #33374 -- Fixed ExpressionWrapper annotations with full queryset.David Wobrock
2021-12-14Fixed #33358 -- Fixed handling timedelta < 1 day in schema operations on Oracle.mdalp
2021-12-13Refs #33355 -- Fixed Trunc() with years < 1000 on SQLite.Adam Johnson
Thanks to Nick Pope for spotting the bug in Code Review. Co-Authored-By: Nick Pope <nick@nickpope.me.uk>
2021-12-10Refs #32502 -- Avoided table rebuild when adding fields with no default on ↵Mariusz Felisiak
SQLite.
2021-12-10Fixed DatabaseFeatures.requires_literal_defaults on SQLite.Mariusz Felisiak
This flag is currently unused on SQLite because it doesn't support dropping a DEFAULT clause, however it requires literal defaults, rather than parameterized ones, so we can set it for clarity.
2021-12-10Refs #32502 -- Added SchemaEditor.prepare_default() on SQLite.Mariusz Felisiak
2021-12-10Corrected return value of ForeignKey.db_check().Adam Johnson
Field.db_check() should return None or a SQL string. Returning [] happened to work because it’s falsey.
2021-12-09Fixed #33340 -- Fixed unquoted column names in queries used by DatabaseCache.Arsa
2021-12-08Fixed #33319 -- Fixed crash when combining with the | operator querysets ↵Ömer Faruk Abacı
with aliases that conflict.
2021-12-08Refs #33319 -- Added comment about keys/values assertion in ↵Ömer Faruk Abacı
Query.change_aliases().
2021-12-07Refs #25265 -- Allowed customizing Query's datastructure classes.Erik Cederstrand
2021-12-07Fixed #31765 -- Enforced enhanced ALTER TABLE behavior for SQLite connections.Adam Johnson
2021-12-06Fixed #33335 -- Made model validation ignore functional unique constraints.Hannes Ljungberg
Regression in 3aa545281e0c0f9fac93753e3769df9e0334dbaa. Thanks Hervé Le Roy for the report.
2021-12-03Fixed #33333 -- Fixed setUpTestData() crash with models.BinaryField on ↵Mariusz Felisiak
PostgreSQL. This makes models.BinaryField pickleable on PostgreSQL. Regression in 3cf80d3fcf7446afdde16a2be515c423f720e54d. Thanks Adam Zimmerman for the report.
2021-12-03Fixed #33339 -- Made QuerySet.bulk_create() use TO_NCLOB() for TextFields on ↵Georgi Yanchev
Oracle.
2021-12-02Updated various links to HTTPS and new locations.Mariusz Felisiak
Co-Authored-By: Nick Pope <nick@nickpope.me.uk>
2021-12-02Fixed #33282 -- Fixed a crash when OR'ing subquery and aggregation lookups.Simon Charette
As a QuerySet resolves to Query the outer column references grouping logic should be defined on the latter and proxied from Subquery for the cases where get_group_by_cols is called on unresolved expressions. Thanks Antonio Terceiro for the report and initial patch.
2021-12-02Refs #32690 -- Altered lookups Query rhs alterations during initialization.Simon Charette
Having it happen at the lookup creation time ensures entry points called before the compilation phase (e.g. get_group_by_cols) don't have to duplicate the logic in charge of altering Query instances used as rhs. It also has the nice effect of reducing the amount of time the alteration logic to once as opposed to multiple times if the queryset is compiled more than once.
2021-12-01Fixed #30398 -- Added CONN_HEALTH_CHECKS database setting.Przemysław Suliga
The CONN_HEALTH_CHECKS setting can be used to enable database connection health checks for Django's persistent DB connections. Thanks Florian Apolloner for reviews.
2021-11-29Fixed #33322 -- Fixed loss of assigned related object when saving relation ↵Hannes Ljungberg
with bulk_update().
2021-11-25Removed unneeded can_use_chunked_reads feature flag on SQLite.Mariusz Felisiak
Unneeded since c0e3c65b9d1b26cfc38137b7666ef0e108aab77f.
2021-11-24Removed unneeded supports_combined_alters feature flag on Oracle.Mariusz Felisiak
supports_combined_alters is False by default.
2021-11-23Fixed #33309 -- Fixed QuerySet.distinct() crash on mixed case annotation.arsalan.ghassemi
2021-11-23Fixed #33304 -- Allowed passing string expressions to Window(order_by).Simon Charette
2021-11-23Refs #33304 -- Enclosed aggregate ordering logic in an expression.Simon Charette
This greatly simplifies the implementation of contrib.postgres' OrderableAggMixin and allows for reuse in Window expressions.
2021-11-22Fixed #33305 -- Fixed autodetector crash for ForeignKey with hardcoded "to" ↵Baptiste Mispelon
attribute. Co-authored-by: Simon Charette <charette.s@gmail.com>
2021-11-19Fixed #33229 -- Fixed ↵SwastikTripathi
BaseDatabaseOperations.adapt_datetimefield_value()/adapt_timefield_value() crash with expressions.
2021-11-19Refs #24121 -- Added __repr__() to BaseDatabaseWrapper, JoinPromoter, and ↵Jonny Park
SQLCompiler.
2021-11-15Refs #33288 -- Removed SQLite's ↵Simon Charette
DatabaseIntrospection._get_foreign_key_constraints(). The get_relations() method returns the exact same data in a more generic format.
2021-11-15Fixed #33288 -- Made SQLite introspection use information schema for relations.Simon Charette
Previous solution was using brittle and complex parsing rules to extract them from the SQL used to define the tables. Removed a now unnecessary unit test that ensured the removed parsing logic accounted for optional spacing.
2021-11-15Refs #33288 -- Made SQLite introspection raise DatabaseError on nonexistent ↵Simon Charette
tables. All the other backends behave this way and we had to make adjustments to our test suite to account for this discrepancy. This also allows SQLite's get_relations() not to raise on a nonexistent table while making sure the InspectDBTestCase.test_introspection_errors test which ensures an error during introspection is surfaced in generated models files still passes.
2021-11-12Fixed #33161 -- Enabled durability check for nested atomic blocks in TestCase.Krzysztof Jagiello
Co-Authored-By: Adam Johnson <me@adamj.eu>
2021-11-12Fixed #33279 -- Fixed handling time zones with "-" sign in names.Can Sarigol
Thanks yakimka for the report. Regression in fde9b7d35e4e185903cc14aa587ca870037941b1.
2021-11-10Removed DatabaseIntrospection.get_key_columns().Mariusz Felisiak
Thanks Simon Charette for the report.
2021-11-10Fixed DatabaseIntrospection.get_relations() docstring.Tim Graham
The foreign keys are "in" the given table, not "to" it.
2021-11-08Fixed #33257 -- Fixed Case() and ExpressionWrapper() with decimal values on ↵Matthijs Kooijman
SQLite.
2021-11-08Fixed #32980 -- Made models cache related managers.Keryn Knight
2021-11-04Fixed #33262 -- Fixed crash of conditional aggregation on Exists().Hannes Ljungberg
2021-11-03Fixed #33260 -- Fixed crash when chaining QuerySet.exists() after ↵Hannes Ljungberg
select_for_update(of=()).
2021-11-03Fixed #32996 -- Cached PathInfos on relations.Keryn Knight
PathInfo values are ostensibly static over the lifetime of the object for which they're requested, so the data can be memoized, quickly amortising the cost over the process' duration.
2021-11-02Fixed #32691 -- Made Exact lookup on BooleanFields compare directly to a ↵Roman
boolean value on MySQL. Performance regression in 37e6c5b79bd0529a3c85b8c478e4002fd33a2a1d. Thanks Todor Velichkov for the report. Co-authored-by: Mariusz Felisiak <felisiak.mariusz@gmail.com>
2021-11-02Fixed #33234 -- Fixed autodetector crash for proxy models inheriting from ↵Mariusz Felisiak
non-model class. Regression in aa4acc164d1247c0de515c959f7b09648b57dc42. Thanks Kevin Marsh for the report.
2021-11-02Fixed #33224 -- Removed ↵Hasan Ramezani
DatabaseFeatures.supports_mixed_date_datetime_comparisons.
2021-10-28Fixed #33228 -- Changed value of ↵Chinmoy
BaseDatabaseFeatures.has_case_insensitive_like to False.
2021-10-28Removed unused model's Options.installed.Mariusz Felisiak
Unused since f9698c43918c118a29516cbef4e23c197eb2dc25.
2021-10-27Fixed #33201 -- Made RenameModel operation a noop for models with db_table.Iuri de Silvio
