Ensure (+) is rendered for all right-hand members

2017-09-13T18:53:29+00:00

Fixed bug where Oracle 8 "non ansi" join mode would not add the
``(+)`` operator to expressions that used an operator other than the
``=`` operator.  The ``(+)`` needs to be on all columns that are part
of the right-hand side.

First level repair for cx_Oracle 6.0 test regressions

2017-08-18T17:04:14+00:00

Fixed more regressions caused by cx_Oracle 6.0; at the moment, the only
behavioral change for users is disconnect detection now detects for
cx_Oracle.DatabaseError in addition to cx_Oracle.InterfaceError, as
this behavior seems to have changed.   Other issues regarding numeric
precision and uncloseable connections are pending with the upstream
cx_Oracle issue tracker.

Ensure Oracle index w/ col DESC etc. is reflected

2017-08-14T05:18:06+00:00

Fixed bug where an index reflected under Oracle with an expression like
"column DESC" would not be returned, if the table also had no primary
key, as a result of logic that attempts to filter out the
index implicitly added by Oracle onto the primary key columns.

Reworked the "filter out the primary key index" logic in oracle
get_indexes() to be clearer.

This changeset also adds an internal check to ColumnCollection
to accomodate for the case of a column being added twice,
as well as adding a private _table argument to Index such that
reflection can specify the Table explicitly.  The _table
argument can become part of public API in a later revision
or release if needed.

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.

Remove twophase for cx_Oracle 6.x

2017-05-23T19:42:06+00:00

Support for two-phase transactions has been removed entirely for
cx_Oracle when version 6.0b1 or later of the DBAPI is in use.  The two-
phase feature historically has never been usable under cx_Oracle 5.x in
any case, and cx_Oracle 6.x has removed the connection-level "twophase"
flag upon which this feature relied.

Use regexp to parse cx_oracle version string

2017-05-09T16:18:27+00:00

Fixed bug in cx_Oracle dialect where version string parsing would
fail for cx_Oracle version 6.0b1 due to the "b" character.  Version
string parsing is now via a regexp rather than a simple split.

Use config.db global opts as defaults for all testing_engine()

2017-03-22T14:13:15+00:00

Some options need to be passed to engines in all cases,
such as currently the oracle 12516 workaround.   make sure
calls to testing_engine also set up the dictionary with
defaults even if options is passed.    not clear if this affects
other backends yet.

New features from python 2.7

After bump minimum supported version to 2.7 (1da9d3752160430c91534a8868ceb8c5ad1451d4), we can use new syntax.
