[orm] [bug] [regression] Fixed regression in selectinload loader strategy that would cause it to
cache its internal state incorrectly when handling relationships that join
across more than one column, such as when using a composite foreign key.
The invalid caching would then cause other unrelated loader operations to
fail.
[orm] [bug] [regression] Fixed regression where _orm.Query.filter_by() would not work if the
lead entity were a SQL function or other expression derived from the
primary entity in question, rather than a simple entity or column of that
entity. Additionally, improved the behavior of
_sql.Select.filter_by() overall to work with column expressions even
in a non-ORM context.
[orm] [bug] [regression] Fixed regression where using _orm.selectinload() and
_orm.subqueryload() to load a two-level-deep path would lead to an
attribute error.
[orm] [bug] [regression] Fixed regression where using the _orm.noload() loader strategy in
conjunction with a "dynamic" relationship would lead to an attribute error
as the noload strategy would attempt to apply itself to the dynamic loader.
[engine] [bug] [regression] Restored a legacy transactional behavior that was inadvertently removed
from the _engine.Connection as it was never tested as a known use
case in previous versions, where calling upon the
_engine.Connection.begin_nested() method, when no transaction is
present, does not create a SAVEPOINT at all and instead starts an outer
transaction, returning a RootTransaction object instead of a
NestedTransaction object. This RootTransaction then
will emit a real COMMIT on the database connection when committed.
Previously, the 2.0 style behavior was present in all cases that would
autobegin a transaction but not commit it, which is a behavioral change.
