The 'db' and 'passwd' connection options have been deprecated, use
'database' and 'password' instead (available since mysqlclient >= 1.3.8).
This also allows the 'database' option in DATABASES['OPTIONS'] on MySQL.
- Replaced datetime.utcnow() with datetime.now().
- Replaced datetime.utcfromtimestamp() with datetime.fromtimestamp().
- Replaced datetime.utctimetuple() with datetime.timetuple().
- Replaced calendar.timegm() and datetime.utctimetuple() with datetime.timestamp().
In Python 3.9.5+ urllib.parse() automatically removes ASCII newlines
and tabs from URLs [1, 2]. Unfortunately it created an issue in
the URLValidator. URLValidator uses urllib.urlsplit() and
urllib.urlunsplit() for creating a URL variant with Punycode which no
longer contains newlines and tabs in Python 3.9.5+. As a consequence,
the regular expression matched the URL (without unsafe characters) and
the source value (with unsafe characters) was considered valid.

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 3543129822.
Thanks James A. Munsch for the report.
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 bbf141bcdc.
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 bbf141bcdc.
Thanks Zain Patel for the report and Simon Charette for reviews.
The exception introduced in 6307c3f1a1
revealed a possible data loss issue in the admin.
Regression in 3a505c70e7.
Nonlitteral right-hand-sides of lookups need to be wrapped in
parentheses to avoid operator precedence ambiguities.
Thanks Charles Lirsac for the detailed report.
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().
This issue started manifesting itself when nesting a combined subquery
relying on exclude() since 8593e162c9 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.
Django apps initialization to run management command triggers the admin
autodiscovery. Importing django.contrib.auth.tokens creates an instance
of PasswordResetTokenGenerator which required a SECRET_KEY.
For several management commands, the token generator is unused. It
should only complain about a missing SECRET_KEY when it is used.
Deferred accessing the module-global variable __file__ because the
Python import API does not guarantee it always exists—in particular, it
does not exist in certain "frozen" environments. The following changes
advanced this goal.
Thanks to Carlton Gibson, Tom Forbes, Mariusz Felisiak, and Shreyas
Ravi for review and feedback.
View.as_view() should not use update_wrapper() for copying attributes
it's unintended and have side-effects such as adding `self` to the
signature.
This also fixes system check for arguments of custom error handler
views with class-based views.

When a partial function was passed as the view, the __repr__() would
show the `func` argument as `functools.partial` which isn't very
helpful, especially as it doesn't reveal the underlying function or
arguments provided.
This simplifies and optimizes runner.py's test_match_tags() because it
(1) uses isdisjoint() instead of intersection(), which involves
constructing a new set, (2) eliminates a set operation when tags is
falsey, (3) eliminates the need for a matched_tags variable, and (4)
uses fewer not's, which should make it easier to parse and understand.
Failures detected when loading tests are ordered before all of the
above for quicker feedback. This includes things like test modules that
couldn't be found or that couldn't be loaded due to syntax errors.
