2022-03-02Fixed #33553 -- Used built-in math functions in SQLite 3.35+.Nick Pope
In SQLite 3.35+ some math functions are available built-in as long as they are not disabled at compile time. We can introspect this and use these built-in functions in preference to our slower implementations.
2022-02-18Fixed #33379 -- Added minimum database version checks.Hasan Ramezani
Thanks Tim Graham for the review.
2022-02-11Refs #32502 -- Avoided table rebuild when removing fields on SQLite 3.35.5+.Mariusz Felisiak
ALTER TABLE ... DROP COLUMN was introduced in SQLite 3.35+ however a data corruption issue was fixed in SQLite 3.35.5.

2022-01-24Fixed #33460 -- Used VALUES clause for insert in bulk on SQLite.Keryn Knight
SQLite 3.7.11 introduced the ability to use multiple values directly. SQLite 3.8.8 made multiple values not subject to the SQLITE_LIMIT_COMPOUND_SELECT (500).
2022-01-19Fixed #31685 -- Added support for updating conflicts to QuerySet.bulk_create().sean_c_hsu
Thanks Florian Apolloner, Chris Jerdonek, Hannes Ljungberg, Nick Pope, and Mariusz Felisiak for reviews.

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
2021-12-07Fixed #31765 -- Enforced enhanced ALTER TABLE behavior for SQLite connections.Adam Johnson

Unneeded since c0e3c65b9d1b26cfc38137b7666ef0e108aab77f.
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 #33279 -- Fixed handling time zones with "-" sign in names.Can Sarigol
Thanks yakimka for the report. Regression in fde9b7d35e4e185903cc14aa587ca870037941b1.

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.

DatabaseFeatures.supports_mixed_date_datetime_comparisons.
2021-10-28Fixed #33228 -- Changed value of ↵Chinmoy
BaseDatabaseFeatures.has_case_insensitive_like to False.
2021-10-26Fixed #32672 -- Fixed introspection of primary key constraints on SQLite.Anv3sh
Thanks Simon Charette for the implementation idea.
2021-10-12Fixed #28401 -- Allowed hashlib.md5() calls to work with FIPS kernels.Ade Lee
md5 is not an approved algorithm in FIPS mode, and trying to instantiate a hashlib.md5() will fail when the system is running in FIPS mode. md5 is allowed when in a non-security context. There is a plan to add a keyword parameter (usedforsecurity) to hashlib.md5() to annotate whether or not the instance is being used in a security context. In the case where it is not, the instantiation of md5 will be allowed. See https://bugs.python.org/issue9216 for more details. Some downstream python versions already support this parameter. To support these versions, a new encapsulation of md5() has been added. This encapsulation will pass through the usedforsecurity parameter in the case where the parameter is supported, and strip it if it is not.
