Black 23.1.0 is released which, as the first release of the year,
introduces the 2023 stable style. This incorporates most of last year's
preview style.
https://github.com/psf/black/releases/tag/23.1.0
Backport of 097e3a70c1481ee7b042b2edd91b2be86fb7b5b6 from main.
Thanks Splunk team: Preston Elder, Jacob Davis, Jacob Moore,
Matt Hanson, David Briggs, and a security researcher: Danylo Dmytriiev
(DDV_UA) for the report.
In these cases Black produces unexpected results, e.g.
def make_random_password(
self,
length=10,
allowed_chars='abcdefghjkmnpqrstuvwxyz' 'ABCDEFGHJKLMNPQRSTUVWXYZ' '23456789',
):
or
cursor.execute("""
SELECT ...
""",
[table name],
)
This reverts commit e441847ecae99dd1ccd0d9ce76dbcff51afa863c.
A shallow copy is not enough because querysets can be reused and
evaluated in nested nodes, which shouldn't mutate JOIN aliases.
Thanks Michal Čihař for the report.
Address a long standing bug in a Where.add optimization to discard
equal nodes that was surfaced by implementing equality for Lookup
instances in bbf141bcdc31f1324048af9233583a523ac54c94.
Thanks Shaheed Haque for the report.
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.
This also replaces assertQuerysetEqual() to
assertSequenceEqual()/assertCountEqual() where appropriate.

As mentioned in the pre-existing split_exclude() docstring EXISTS is
easier to optimize for query planers and circumvents the IN (NULL)
handling issue.
Now that order_by() has expression support passing RawSQL() can achieve
the same result.
This was also already supported through QuerySet.extra(order_by) for
years but this API is more or less deprecated at this point.
OuterRef right hand sides have to be nested, just like F rhs have to,
during the subquery pushdown split_exclude performs to ensure they are
resolved against the outer query aliases.
Expressions referring to different bound fields should not be
considered equal.
Thanks Julien Enselme for the detailed report.
Regression in bc7e288ca9554ac1a0a19941302dea19df1acd21.
This makes Subquery a thin wrapper over Query and makes sure it respects
the Expression source expression API by accepting the same number of
expressions as it returns. Refs #30188.
It also makes OuterRef usable in Query without Subquery wrapping. This
should allow Query's internals to more easily perform subquery push downs
during split_exclude(). Refs #21703.
