[orm] [usecase] Altered some of the behavior repaired in #6232 where the
immediateload loader strategy no longer goes into recursive loops; the
modification is that an eager load (joinedload, selectinload, or
subqueryload) from A->bs->B which then states immediateload for a
simple manytoone B->a->A that's in the identity map will populate the B->A,
so that this attribute is back-populated when the collection of A/A.bs are
loaded. This allows the objects to be functional when detached.
[orm] [bug] Fixed bug in new _orm.with_loader_criteria() feature where using a
mixin class with _orm.declared_attr() on an attribute that were
accessed inside the custom lambda would emit a warning regarding using an
unmapped declared attr, when the lambda callable were first initialized.
This warning is now prevented using special instrumentation for this
lambda initialization step.
[orm] [bug] [regression] Fixed additional regression caused by the "eagerloaders on refresh" feature
added in #1763 where the refresh operation historically would set
populate_existing, which given the new feature now overwrites pending
changes on eagerly loaded objects when autoflush is false. The
populate_existing flag has been turned off for this case and a more
specific method used to ensure the correct attributes refreshed.
[orm] [bug] [result] Fixed an issue when using 2.0 style execution that prevented using
_result.Result.scalar_one() or
_result.Result.scalar_one_or_none() after calling
_result.Result.unique(), for the case where the ORM is returning a
single-element row in any case.
[sql] [bug] Fixed issue in SQL compiler where the bound parameters set up for a
Values construct wouldn't be positionally tracked correctly if
inside of a _sql.CTE, affecting database drivers that support
VALUES + ctes and use positional parameters such as SQL Server in
particular as well as asyncpg. The fix also repairs support for
compiler flags such as literal_binds.
