to import rdbms_apiproxy vs. rdbms_googleapi to work
on both dev and production platforms. Also now honors the
``instance`` attribute. Courtesy Sean Lynch. Also backported
enhancements to allow username/password as well as
fixing error code interpretation from 0.8.
[ticket:2649]
arbitrary number of :func:`.sessionmaker` objects
were created. The anonymous subclass created by
the sessionmaker, when dereferenced, would not be garbage
collected due to remaining class-level references from the
event package. This issue also applies to any custom system
that made use of ad-hoc subclasses in conjunction with
an event dispatcher. [ticket:2650]
0.7.9, to intercept legacy SQLite quoting characters when reflecting
foreign keys. In addition to intercepting double quotes, other
quoting characters such as brackets, backticks, and single quotes
are now also intercepted. [ticket:2568]
without passing the "for_update=True" flag would apply the default
object to the server_default, blowing away whatever was there.
The explicit for_update=True argument shouldn't be needed with this usage
(especially since the documentation shows an example without it being
used) so it is now arranged internally using a copy of the given default
object, if the flag isn't set to what corresponds to that argument.
[ticket:2631]
to use the cx_Oracle.LOB type when result rows are returned,
so the dialect has been repaired to exclude LONG from
having cx_Oracle.LOB filtering applied.
[ticket:2620]
cx_Oracle so that a return value of ``False`` will result
in no call to ``connection.commit()``, hence avoiding
"no transaction" errors. Two-phase transactions have
now been shown to work in a rudimental fashion with
SQLAlchemy and cx_oracle, however are subject to caveats
observed with the driver; check the documentation
for details. [ticket:2611]
:meth:`.MutableBase.coerce` method to be used, even though
the code seemed to indicate this intent, so this now works
and a brief example is added. As a side-effect,
the mechanics of this event handler have been changed so that
new :class:`.MutableComposite` types no longer add per-type
global event handlers. Also in 0.8.0b2.
[ticket:2624]
in conjunction with "schema" for the owning
Table would fail to locate result rows due
to the MSSQL dialect's "schema rendering"
logic's failure to take .key into account.
[ticket:2607]
excluded from the setinputsizes() step to only include
STRING and UNICODE; CLOB and NCLOB are removed. This
is to work around cx_oracle behavior which is broken
for the executemany() call. In 0.8, this same change
is applied however it is also configurable via the
exclude_setinputsizes argument. [ticket:2561]
a deleted object in the identity map with another
object of the same primary key would raise a
"conflicting state" error on rollback(),
if the replaced primary key were established either
via non-unitofwork-established INSERT statement
or by primary key switch of another instance.
[ticket:2583]
passing an empty list for either partition_by
or order_by, as opposed to None, would fail
to generate correctly.

[ticket:2574]
subquery within an ORDER BY would fail to render correctly
if the stament also used LIMIT/OFFSET, due to mis-rendering
within the ROW_NUMBER() OVER clause. Fix courtesy
