Drops support for cx_Oracle prior to version 5.x, reworks
numeric and binary support.
Fixes: #4064

unfortunately the synonym doesn't work for SQL statements here
when the dblink is on a different user, testing this is not really
critical so just removed it.
consists mainly of adjusting fixtures to ensure connections are closed
explicitly. psycopg2cffi also handles unicode bind parameter
names differently than psycopg2, and seems to possibly have a little less
control over floating point values at least in one test which is
marked as a "fail", though will see if it runs differently on linux
than osx..

"supports unicode statements" flag is now False, so that SQLAlchemy
will encode the *SQL string* (note: *not* the parameters)
to bytes before sending to the database. This seems to allow
all unicode-related tests to pass for mysql-connector, including those
that use non-ascii table/column names, as well as some tests for the
TEXT type using unicode under cursor.executemany().
- other mysql-connector fixes; latest version seems to do better on
function call counts
is currently being supported in addition to nose, and will likely
be preferred to nose going forward. The nose plugin system used
by SQLAlchemy has been split out so that it works under pytest as
well. There are no plans to drop support for nose at the moment
and we hope that the test suite itself can continue to remain as
agnostic of testing platform as possible. See the file
README.unittests.rst for updated information on running tests
with pytest.
The test plugin system has also been enhanced to support running
tests against mutiple database URLs at once, by specifying the ``--db``
and/or ``--dburi`` flags multiple times. This does not run the entire test
suite for each database, but instead allows test cases that are specific
to certain backends make use of that backend as the test is run.
When using pytest as the test runner, the system will also run
specific test suites multiple times, once for each database, particularly
those tests within the "dialect suite". The plan is that the enhanced
system will also be used by Alembic, and allow Alembic to run
migration operation tests against multiple backends in one run, including
third-party backends not included within Alembic itself.
Third party dialects and extensions are also encouraged to standardize
on SQLAlchemy's test suite as a basis; see the file README.dialects.rst
for background on building out from SQLAlchemy's test platform.
pymysql) from working in Py3K, where a check for "connection
charset" would fail due to Py3K's more strict value comparison
rules. The call in question wasn't taking the database
version into account in any case as the server version was
still None at that point, so the method overall has been
simplified to rely upon connection.character_set_name().

to a DBLINK remote database; while the syntax has been present in the
Oracle dialect for some time, up until now it has never been tested.
The syntax has been tested against a sample database linking to itself,
however there's still some uncertainty as to what should be used for the
"owner" when querying the remote database for table information.
Currently, the value of "username" from user_db_links is used to
match the "owner". [ticket:2619]
become an externally usable package but still remains within the main sqlalchemy parent package.
in this system, we use kind of an ugly hack to get the noseplugin imported outside of the
"sqlalchemy" package, while still making it available within sqlalchemy for usage by
third party libraries.
- bootstrap and lib move to all absolute imports
- testing.py is no longer internally referenced.
- requirements move to be a pluggable class which can
be overridden.
- cleanup
in the interests of third party testing, test/lib and test/bootstrap
may move to be an independent package.
column, and the "autoincrement" feature of various dialects
as well as the "sqlite_autoincrement" flag will honor
the underlying database type as being Integer-based.
[ticket:2005]
- Result-row processors are applied to pre-executed SQL
defaults, as well as cursor.lastrowid, when determining
the contents of result.inserted_primary_key.
[ticket:2006]
- Bind parameters present in the "columns clause" of a select
are now auto-labeled like other "anonymous" clauses,
which among other things allows their "type" to be meaningful
when the row is fetched, as in result row processors.
- TypeDecorator is present in the "sqlalchemy" import space.
outside of "sqlalchemy" and under "test/".
Rationale:
- coverage plugin works without issue, without need for an awkward
additional package install
- command line for "nosetests" isn't polluted with SQLAlchemy options
[ticket:1949]
- added READMEs to all examples in each __init__.py and added to sphinx documentation
- added versioning example
- removed vertical/vertical.py, the dictlikes are more straightforward
