See what happens if we setinputsizes for String

2017-07-28T22:04:02+00:00

Per Anthony Tuininga, setinputsizes() is important
particularly if you have a unicode value you want to line
up with an index under Python 3, because you want the type
to be bound using NVARCHAR2 and not VARCHAR2.   Only if
we setinputsizes() for NVARCHAR2 will we get that effect.
So see at least if setinputsizes() works for STRING these
days or otherwise figure out what the problem was.

Additionally, the type object now for NVARCHAR2 is
cx_Oracle.NCHAR, so use that, and also remove some
old _cx_oracle_XYZ collections we aren't using to
reduce verbosity.

Revert cx_Oracle WITH_UNICODE change under > 5.0

2017-07-28T21:36:08+00:00

Fixed performance regression caused by the fix for :ticket:`3937` where
cx_Oracle as of version 5.3 dropped the ``.UNICODE`` symbol from its
namespace,  which was interpreted as cx_Oracle's "WITH_UNICODE" mode being
turned on unconditionally, which invokes functions on the SQLAlchemy
side which convert all strings to unicode unconditionally and causing
a performance impact.  In fact, per cx_Oracle's author the
"WITH_UNICODE" mode has been removed entirely as of 5.1, so the expensive unicode
conversion functions are no longer necessary and are disabled if
cx_Oracle 5.1 or greater is detected under Python 2.  The warning against
"WITH_UNICODE" mode that was removed under :ticket:`3937` is also restored.

Guard all indexed access in WeakInstanceDict

2017-07-24T15:48:13+00:00

Added ``KeyError`` checks to all methods within
:class:`.WeakInstanceDict` where a check for ``key in dict`` is
followed by indexed access to that key, to guard against a race against
garbage collection that under load can remove the key from the dict
after the code assumes its present, leading to very infrequent
``KeyError`` raises.

Check for column object in eval_none, not propkey

2017-07-18T19:04:36+00:00

Fixed bug involving JSON NULL evaluation logic added in 1.1 as part
of :ticket:`3514` where the logic would not accommodate ORM
mapped attributes named differently from the :class:`.Column`
that was mapped.

Check for non-entity when inspecting for subqueryload

2017-07-18T19:02:39+00:00

Fixed issue where adding additional non-entity columns to
a query that includes an entity with subqueryload relationships
would fail, due to an inspection added in 1.1.11 as a result of
:ticket:`4011`.
