Allow Table._reset_exported to silently pass

2016-07-25T03:17:11+00:00

Fixed bug in :class:`.Table` where the internal method
``_reset_exported()`` would corrupt the state of the object.  This
method is intended for selectable objects and is called by the ORM
in some cases; an erroneous mapper configuration would could lead the
ORM to call this on on a :class:`.Table` object.

- MySQL's JSON shared implementation completely w/ sqltypes.JSON;

2016-07-25T03:14:47+00:00

this must have been an oversight.   Leave mysql.JSON in place still
as we might need to add things to it.
- CAST(json, String) still confusing MySQL drivers even mysqlclient.
Since here we're checking for the raw form of the JSON and not a typical
round trip, add a force for unicode

Remove same-named relationship warning

2016-07-19T16:36:21+00:00

Removed a warning that dates back to 0.4 which emits when a same-named
relationship is placed on two mappers that inherits via joined or
single table inheritance.   The warning does not apply to the
current unit of work implementation.

Ensure DML provides named_with_column for CTE(Alias)

2016-07-13T15:49:34+00:00

Fixed bug in new CTE feature for update/insert/delete whereby
an anoymous (e.g. no name passed) :class:`.CTE` construct around
the statement would fail.  The Alias base class of CTE checks
for the "named_with_column" attribute in order to detect if
the underlying selectable has a name; UpdateBase now provides
this as False.

Merge "Work w/ prefetch even for selects, if present"

Work w/ prefetch even for selects, if present

2016-07-12T20:43:49+00:00

Fixed bug in new CTE feature for update/insert/delete stated
as a CTE inside of an enclosing statement (typically SELECT) whereby
oninsert and onupdate values weren't called upon for the embedded
statement.

This is accomplished by consulting prefetch
for all statements.  The collection is also broken into
separate insert/update collections so that we don't need to
consult toplevel self.isinsert to determine if the prefetch
is for an insert or an update.  What we don't yet test for
are CTE combinations that have both insert/update in one
statement, though these should now work in theory provided
the underlying database supports such a statement.
