This is a follow up for the fix of CVE-2024-39329
(5d8645857936c142a3973694799c52165e2bdcdb) where the timing of
verify_password() was standardized when checking unusable passwords.
Regression in b0ad41198b3e333f57351e3fce5a1fb47f23f376.
Refs #34013. The initial logic did not consider that annotation aliases
can include lookup or transform separators.
Thanks Gert Van Gool for the report and Mariusz Felisiak for the review.
LocaleMiddleware didn't handle the ValueError raised by
get_supported_language_variant() when language codes were
over 500 characters.

This is the exact same issue as refs #30408 but for creating a model with a
constraint containing % escapes instead of column addition. All of these issues
stem from a lack of SQL and parameters separation from the BaseConstraint DDL
generating methods preventing them from being mixed with other parts of the
schema alteration logic that do make use of parametrization on some backends
(e.g. Postgres, MySQL for DEFAULT).
Prior to the addition of Field.db_default and GeneratedField in 5.0
parametrization of DDL was never exercised on model creation so this is
effectively a bug with db_default as the GeneratedField case was addressed by
refs #35336.
Thanks Julien Chaumont for the report and Mariusz Felisiak for the review.
Partially reverts 0b33a3abc2ca7d68a24f6d0772bc2b9fa603744e.
Storage.exists(name) was documented to "return False if
the name is available for a new file." but return True if
the file exists. This is ambiguous in the overwrite file
case. It will now always return whether the file exists.
Thank you to Natalia Bidart and Josh Schneier for the
review.
While refs #34125 focused on the SQL correctness of slicing of union of
potentially empty queries it missed an optimization opportunity to avoid
performing a query at all when all queries are empty.
Thanks Lucidiot for the report.
The original tests required the creation of a model that is no longer necessary
and were exercising Model.full_clean(validate_constraints) which has nothing
to do with the nulls_distinct feature.
The logic allowing UniqueConstraint(fields).validate to preserve backward
compatiblity with Model.unique_error_message failed to account for cases where
the constraint might not be attached to a model which is a common pattern
during testing.
This changes allows for arbitrary UniqueConstraint(fields) to be tested in
isolation without requiring actual models backing them up.
