[orm] [bug] As more projects are using new-style "2.0" ORM querying, it's becoming
apparent that the conditional nature of "autoflush", being based on whether
or not the given statement refers to ORM entities, is becoming more of a
key behavior. Up until now, the "ORM" flag for a statement has been loosely
based around whether or not the statement returns rows that correspond to
ORM entities or columns; the original purpose of the "ORM" flag was to
enable ORM-entity fetching rules which apply post-processing to Core result
sets as well as ORM loader strategies to the statement. For statements
that don't build on rows that contain ORM entities, the "ORM" flag was
considered to be mostly unnecessary.
It still may be the case that "autoflush" would be better taking effect for
all usage of _orm.Session.execute() and related methods, even for
purely Core SQL constructs. However, this still could impact legacy cases
where this is not expected and may be more of a 2.1 thing. For now however,
the rules for the "ORM-flag" have been opened up so that a statement that
includes ORM entities or attributes anywhere within, including in the WHERE
/ ORDER BY / GROUP BY clause alone, within scalar subqueries, etc. will
enable this flag. This will cause "autoflush" to occur for such statements
and also be visible via the _orm.ORMExecuteState.is_orm_statement
event-level attribute.
[postgresql] [bug] [regression] Repaired the base Uuid datatype for the PostgreSQL dialect to
make full use of the PG-specific UUID dialect-specific datatype when
"native_uuid" is selected, so that PG driver behaviors are included. This
issue became apparent due to the insertmanyvalues improvement made as part
of #9618, where in a similar manner as that of #9739, the
asyncpg driver is very sensitive to datatype casts being present or not,
and the PostgreSQL driver-specific native UUID datatype must be invoked
when this generic type is used so that these casts take place.
