delta/python-packages/django.git/tests/delete, branch c/32409-async-tests-cannot-call-orm

Fixed #32107 -- Fixed ProtectedError.protected_objects and RestrictedError.restricted_objects.

2020-10-19T10:43:32+00:00

Regression in 4ca5c565f4dc9e97845036e86416abc5cfde766c and
ab3cbd8b9a315911248227208630a020cedca08f.

Fixed #31965 -- Adjusted multi-table fast-deletion on MySQL/MariaDB.

2020-08-31T06:11:28+00:00

The optimization introduced in 7acef095d73 did not properly handle
deletion involving filters against aggregate annotations.

It initially was surfaced by a MariaDB test failure but misattributed
to an undocumented change in behavior that resulted in the systemic
generation of poorly performing database queries in 5b83bae031.

Thanks Anton Plotkin for the report.

Refs #23576.
