OK use tox
update test runners to be module-based
- Fixed bug in :class:`.Enum` and other :class:`.SchemaType`
subclasses where direct association of the type with a
:class:`.MetaData` would lead to a hang when events
(like create events) were emitted on the :class:`.MetaData`.
fixes #3124
PEP8 style fixes
Merge branch 'pep8'
- adjust this to work on PG also
- ensure usedevelop is present so that C exts are in the tests
- add some order bys
- Added a "str()" step to the dialect_kwargs iteration for
Python version < 2.6.5, working around the
"no unicode keyword arg" bug as these args are passed along as
keyword args within some reflection processes.
fixes #3123
need a 1.0.0 here
- Fixed bug where multi-valued :class:`.Insert` construct would fail
to check subsequent values entries beyond the first one given
for literal SQL expressions.
fixes #3069
 -Fixed bug in common table expressions whereby positional bound
parameters could be expressed in the wrong final order
when CTEs were nested in certain ways.
fixes #3090
- Fixed a regression from 0.9.0 due to :ticket:`2736` where the
:meth:`.Query.select_from` method no longer set up the "from
entity" of the :class:`.Query` object correctly, so that
subsequent :meth:`.Query.filter_by` or :meth:`.Query.join`
calls would fail to check the appropriate "from" entity when
searching for attributes by string name.
fixes #3083
- In the SQL Server pyodbc dialect, repaired the implementation
for the ``description_encoding`` dialect parameter, which when
not explicitly set was preventing  cursor.description from
being parsed correctly in the case of result sets that
contained names in alternate encodings.  This parameter
shouldn't be needed going forward.
fixes #3091
- Added statement encoding to the "SET IDENTITY_INSERT"
statements which operate when an explicit INSERT is being
interjected into an IDENTITY column, to support non-ascii table
identifiers on drivers such as pyodbc + unix + py2k that don't
support unicode statements.
ref #3091 as this fix is also in that issue's patch, but is
a different issue.
- Fixed a regression from 0.9.5 caused by :ticket:`3025` where the
query used to determine "default schema" is invalid in SQL Server 2000.
For SQL Server 2000 we go back to defaulting to the "schema name"
parameter of the dialect, which is configurable but defaults
to 'dbo'. fixes #3025
- Fix bug in naming convention feature where using a check
constraint convention that includes ``constraint_name`` would
then force all :class:`.Boolean` and :class:`.Enum` types to
require names as well, as these implicitly create a
constraint, even if the ultimate target backend were one that does
not require generation of the constraint such as Postgresql.
The mechanics of naming conventions for these particular
constraints has been reorganized such that the naming
determination is done at DDL compile time, rather than at
constraint/table construction time.
fixes #3067
- allow the compilation rule that gets the formatted name
to again have the chance to veto rendering, as the naming convention
can make the decision that the name is "none" or not now.
- wrestle with conv() and tests some more
- Fixed a SQLite join rewriting issue where a subquery that is embedded
as a scalar subquery such as within an IN would receive inappropriate
substitutions from the enclosing query, if the same table were present
inside the subquery as were in the enclosing query such as in a
joined inheritance scenario.
fixes #3130
