primary key that has values for some but not all of the PK fields
would emit a SELECT statement leaking the internal NEVER_SET symbol
into the query, rather than detecting that this object does not have
a searchable primary key and no SELECT should be emitted.

INSERT, UPDATE, and DELETE statements to both specify their own
WITH clause, as well as for these statements themselves to be
CTE expressions when they include a RETURNING clause.

:meth:`.Query.distinct` is combined with :meth:`.Query.order_by` such
that columns which are already present will not be added
a second time, even if they are labeled with a different name.
Regardless of this change, the extra columns added to the SQL have
never been returned in the final result, so this change only impacts
the string form of the statement as well as its behavior when used in
a Core execution context. Additionally, columns are no longer added
when the DISTINCT ON format is used, provided the query is not
wrapped inside a subquery due to joined eager loading.

yet cx_Oracle still has open sessions that cannot be killed until process dies.
Oracle wins! Add a completely separate DB reaper script that runs
after py.test is done.

- establish make_transient and make_transient_to_detached as special-use,
advanced use only functions
- list all conditions under make_transient() under which an attribute
will not be loaded and establish that make_transient() does not attempt
to load all attributes before detaching the object from its
session, fixes #3640

unfortunately the synonym doesn't work for SQL statements here
when the dblink is on a different user, testing this is not really
critical so just removed it.

on unicode. Enum would be better as a TypeDecorator
at this point but then that becomes awkward with native enum
types (Interval works that way, but we don't need the bind_processor for
native interval...)

fixes #3095, #3292
- reorganize enum constructor to again work with the MySQL
ENUM type
- add a new create_constraint flag to Enum to complement that of
Boolean
- reinstate the CHECK constraint tests for enum, these already
fail /skip against the MySQL backend
- simplify lookup rules in Enum, have them apply to all varieties
of Enum equally

override with a column expression (e.g. by using ``'x' in col``)
would cause an endless loop in the case of an ARRAY type, as Python
defers this to ``__getitem__`` access which never raises for this
type. Overall, all use of ``__contains__`` now raises
NotImplementedError.

the warning here to all safe_reraise() cases in Python 2.
- Revisiting :ticket:`2696`, first released in 1.0.10, which attempts to
work around Python 2's lack of exception context reporting by emitting
a warning for an exception that was interrupted by a second exception
when attempting to roll back the already-failed transaction; this
issue continues to occur for MySQL backends in conjunction with a
savepoint that gets unexpectedly lost, which then causes a
"no such savepoint" error when the rollback is attempted, obscuring
what the original condition was.
The approach has been generalized to the Core "safe
reraise" function which takes place across the ORM and Core in any
place that a transaction is being rolled back in response to an error
which occurred trying to commit, including the context managers
provided by :class:`.Session` and :class:`.Connection`, and taking
place for operations such as a failure on "RELEASE SAVEPOINT".
Previously, the fix was only in place for a specific path within
the ORM flush/commit process; it now takes place for all transational
context managers as well.

in df3f125bd84fc7ec5d45592c5774daf3a39d9bc9, this flag is
explicitly checked within conftest.py and we need to continue to use
it, otherwise a tox build inside of .tox that isn't usedevelop
is ignored, including C extensions
- rework the whole system of running with coverage, so that
with coverage, we *are* using usedevelop, but also make sure
we rm the .so files for nocext, make sure we --cov-append, etc.

This reverts commit de0d144a395c31eb74084177df95a4858b830f88.
Apparently the test suite is not using the cextensions correctly at the moment.
