Summary:     - fix a regression from ref #3178, where dialects that don't actually support
sane multi rowcount (e.g. pyodbc) would fail on multirow update.  add
a test that mocks this breakage into plain dialects

[Bitbucket <com...@bi...>]

1 new commit in sqlalchemy:

https://bitbucket.org/zzzeek/sqlalchemy/commits/f3a892a3ef66/
Changeset:   f3a892a3ef66
Branch:      None
User:        zzzeek
Date:        2015-01-17 01:03:33+00:00
Summary:     - Custom dialects that implement :class:`.GenericTypeCompiler` can
now be constructed such that the visit methods receive an indication
of the owning expression object, if any.  Any visit method that
accepts keyword arguments (e.g. ``**kw``) will in most cases
receive a keyword argument ``type_expression``, referring to the
expression object that the type is contained within.  For columns
in DDL, the dialect's compiler class may need to alter its
``get_column_specification()`` method to support this as well.
The ``UserDefinedType.get_col_spec()`` method will also receive
``type_expression`` if it provides ``**kw`` in its argument
signature.

https://bitbucket.org/zzzeek/sqlalchemy/commits/79fa69f1f37f/
Changeset:   79fa69f1f37f
Branch:      None
User:        zzzeek
Date:        2015-01-16 23:03:45+00:00
Summary:     - Fixed bug where Postgresql dialect would fail to render an
expression in an :class:`.Index` that did not correspond directly
to a table-bound column; typically when a :func:`.text` construct
was one of the expressions within the index; or could misinterpret the
list of expressions if one or more of them were such an expression.

Changeset:   b63aae2c232f
Branch:      None
User:        zzzeek
Date:        2015-01-13 22:04:35+00:00
Summary:     - The "wildcard" loader options, in particular the one set up by
the :func:`.orm.load_only` option to cover all attributes not
explicitly mentioned, now takes into account the superclasses
of a given entity, if that entity is mapped with inheritance mapping,
so that attribute names within the superclasses are also omitted
from the load.  Additionally, the polymorphic discriminator column
is unconditionally included in the list, just in the same way that
primary key columns are, so that even with load_only() set up,
polymorphic loading of subtypes continues to function correctly.

Branch:      None
User:        zzzeek
Date:        2015-01-13 19:33:33+00:00
Summary:     - The multi-values version of :meth:`.Insert.values` has been
repaired to work more usefully with tables that have Python-
side default values and/or functions, as well as server-side
defaults. The feature will now work with a dialect that uses
"positional" parameters; a Python callable will also be
invoked individually for each row just as is the case with an
"executemany" style invocation; a server- side default column
will no longer implicitly receive the value explicitly
specified for the first row, instead refusing to invoke
without an explicit value. fixes #3288

Branch:      None
User:        zzzeek

Summary:     - Fixed bug where if an exception were thrown at the start of a
:class:`.Query` before it fetched results, particularly when
row processors can't be formed, the cursor would stay open with
results pending and not actually be closed.  This is typically only
an issue on an interpreter like Pypy where the cursor isn't
immediately GC'ed, and can in some circumstances lead to transactions/
locks being open longer than is desirable.

Summary:     - scale back _Dispatch and _JoinedDispatcher to use a __getitem__ scheme
to start up listener collections; this pulls the overhead off of construction
and makes performance much like the descriptor version, while still allowing
slots.   Fix up some profiles.

Summary:     - Structural memory use has been improved via much more significant use
of ``__slots__`` for many internal objects.  This optimization is
particularly geared towards the base memory size of large applications
that have lots of tables and columns, and greatly reduces memory
size for a variety of high-volume objects including event listening
internals, comparator objects and parts of the ORM attribute and
loader strategy system.

Date:        2015-01-04 01:43:45+00:00
Summary:     - The :class:`.mysql.SET` type has been overhauled to no longer
assume that the empty string, or a set with a single empty string
value, is in fact a set with a single empty string; instead, this
is by default treated as the empty set.  In order to handle persistence
of a :class:`.mysql.SET` that actually wants to include the blank
value ``''`` as a legitimate value, a new bitwise operational mode
is added which is enabled by the
:paramref:`.mysql.SET.retrieve_as_bitwise` flag, which will persist
and retrieve values unambiguously using their bitflag positioning.
Storage and retrieval of unicode values for driver configurations
that aren't converting unicode natively is also repaired.

Changeset:   21f47124ab43
Branch:      None
User:        zzzeek
Date:        2015-01-02 01:17:06+00:00
Summary:     - restate sort_tables in terms of a more fine grained
sort_tables_and_constraints function.
- The DDL generation system of :meth:`.MetaData.create_all`
and :meth:`.Metadata.drop_all` has been enhanced to in most
cases automatically handle the case of mutually dependent
foreign key constraints; the need for the
:paramref:`.ForeignKeyConstraint.use_alter` flag is greatly
reduced.  The system also works for constraints which aren't given
a name up front; only in the case of DROP is a name required for
at least one of the constraints involved in the cycle.
fixes #3282
