2021-07-28Refs #32946 -- Changed internal usage of dynamic Q() objects construction to ↵Keryn Knight
use non-kwargs initialization. This prefers non-kwargs construction of dynamically generated Q() objects to create a single Q() object instead of many and then combining them, where possible.

2021-07-12Refs #32074 -- Used Enum.repr() format proposed for Python 3.10.Mariusz Felisiak
The Python's Steering Council decided to revert changes in the Enum module (see https://bugs.python.org/issue44559) and moved them to Python 3.11. Follow up to 5d9b065d3f93de056588dfee6f1776294dd8bab2. Thanks Nick Pope for the review.

2021-07-07Fixed #32840 -- Optimized Field.get_col().Keryn Knight
get_col() used "self" as "output_field" when it was not given, and unnecessarily compared "self" to "self". Co-authored-by: Chris Jerdonek <chris.jerdonek@gmail.com> Co-authored-by: Mariusz Felisiak <felisiak.mariusz@gmail.com>
2021-07-05Fixed #32226 -- Fixed JSON format of QuerySet.explain() on PostgreSQL.Wu Haotian
2021-07-02Refs #26430 -- Re-introduced empty aggregation optimization.Simon Charette
The introduction of the Expression.empty_aggregate_value interface allows the compilation stage to enable the EmptyResultSet optimization if all the aggregates expressions implement it. This also removes unnecessary RegrCount/Count.convert_value() methods. Disabling the empty result set aggregation optimization when it wasn't appropriate prevented None returned for a Count aggregation value. Thanks Nick Pope for the review.
2021-07-02Fixed #26430 -- Fixed coalesced aggregation of empty result sets.Simon Charette
Disable the EmptyResultSet optimization when performing aggregation as it might interfere with coalescence.

2021-05-17Fixed #32750 -- Fixed crash of Extract() transform on OuterRef() expressions.Artur Beltsov
Thanks Simon Charette for the review.
2021-05-13Fixed #32718 -- Relaxed file name validation in FileField.Mariusz Felisiak
- Validate filename returned by FileField.upload_to() not a filename passed to the FileField.generate_filename() (upload_to() may completely ignored passed filename). - Allow relative paths (without dot segments) in the generated filename. Thanks to Jakub Kleň for the report and review. Thanks to all folks for checking this patch on existing projects. Thanks Florian Apolloner and Markus Holtermann for the discussion and implementation idea. Regression in 0b79eb36915d178aef5c6a7bbce71b1e76d376d3.
2021-05-05Fixed #32690 -- Fixed __in lookup crash when combining with filtered aggregates.Simon Charette
Having lookups group by subquery right-hand-sides is likely unnecessary in the first place but relatively large amount of work would be needed to achieve that such as making Lookup instances proper resolvable expressions. Regression in 35431298226165986ad07e91f9d3aca721ff38ec. Thanks James A. Munsch for the report.
2021-05-05Fixed #32714 -- Prevented recreation of migration for Meta.ordering with ↵Simon Charette
OrderBy expressions. Regression in c8b659430556dca0b2fe27cf2ea0f8290dbafecd. Thanks Kevin Marsh for the report.
2021-05-04Fixed CVE-2021-31542 -- Tightened path & file name sanitation in file uploads.Florian Apolloner
2021-05-04Fixed #32693 -- Quoted and lowercased generated column aliases.Hasan Ramezani
2021-04-28Removed unnecessary reuse_with_filtered_relation argument from Query methods.Nick Pope
In Query.join() the argument reuse_with_filtered_relation was used to determine whether to use == or .equals(). As this area of code is related to aliases, we only expect an instance of Join or BaseTable to be provided - the only two classes that provide .equals(). In both cases, the implementations of __eq__() and equals() are based on use of the "identity" property. __eq__() performs an isinstance() check first, returning NotImplemented if required. BaseTable.equals() then does a straightforward equality check on "identity". Join.equals() is a little bit different as it skips checking the last element of the "identity" property: filtered_relation. This was only included previously when the with_filtered_relation argument was True, impossible since bbf141bcdc31f1324048af9233583a523ac54c94.
2021-04-28Removed unused with_filtered_relation argument from .equals()Nick Pope
Unused since bbf141bcdc31f1324048af9233583a523ac54c94.
2021-04-28Fixed #32632, Fixed #32657 -- Removed flawed support for Subquery ↵Simon Charette
deconstruction. Subquery deconstruction support required implementing complex and expensive equality rules for sql.Query objects for little benefit as the latter cannot themselves be made deconstructible to their reference to model classes. Making Expression @deconstructible and not BaseExpression allows interested parties to conform to the "expression" API even if they are not deconstructible as it's only a requirement for expressions allowed in Model fields and meta options (e.g. constraints, indexes). Thanks Phillip Cutter for the report. This also fixes a performance regression in bbf141bcdc31f1324048af9233583a523ac54c94.
2021-04-27Refs #32682 -- Fixed QuerySet.delete() crash on querysets with ↵Mariusz Felisiak
self-referential subqueries on MySQL.
2021-04-23Refs #32673 -- Fixed lookups crash when comparing against lookups on Oracle.Mariusz Felisiak
Follow up to 170b006ce82b0ecf26dc088f832538b747ca0115.
2021-04-23Fixed #32673 -- Fixed lookups crash when comparing against lookups on ↵Simon Charette
PostgreSQL. Regression in 3a505c70e7b228bf1212c067a8f38271ca86ce09. Nonlitteral right-hand-sides of lookups need to be wrapped in parentheses to avoid operator precedence ambiguities. Thanks Charles Lirsac for the detailed report.
2021-04-21Fixed #32662 -- Refactored a generator out of SQLCompiler.get_order_by().Chris Jerdonek
This also renames the `asc` variable to `default_order`, markes the `desc` variable as unused, fixes a typo in SQLCompiler.get_order_by() docstring, and reorders some blocks in SQLCompiler._order_by_pairs().
2021-04-21Fixed #32650 -- Fixed handling subquery aliasing on queryset combination.Simon Charette
This issue started manifesting itself when nesting a combined subquery relying on exclude() since 8593e162c9cb63a6c0b06daf045bc1c21eb4d7c1 but sql.Query.combine never properly handled subqueries outer refs in the first place, see QuerySetBitwiseOperationTests.test_subquery_aliases() (refs #27149). Thanks Raffaele Salmaso for the report.
2021-04-20Refs #25287 -- Added support for multiplying and dividing DurationField by ↵Tobias Bengfort
scalar values on SQLite.
2021-04-20Removed unnecessary line in OrderBy.as_sql().David Beitey
Unnecessary since 7286eaf681d497167cd7dc8b70ceebfcf5cd21ad.
2021-04-14Fixed #32635 -- Fixed system check crash for reverse o2o relations in ↵Hasan Ramezani
CheckConstraint.check and UniqueConstraint.condition. Regression in b7b7df5fbcf44e6598396905136cab5a19e9faff. Thanks Szymon Zmilczak for the report.
