The tuple returned by :attr:`.CursorResult.inserted_primary_key` is now a
:class:`_result.Row` object with a named tuple interface on top of the
existing tuple interface.

continuing with producing a SQLAlchemy 1.4.0b2 that internally
does not emit any of its own 2.0 deprecation warnings,
migrate the *args and **kwargs passed to execute() methods
that now must be a single list or dictionary.
Alembic 1.5 is again waiting on this internal consistency to
be present so that it can pass all tests with no 2.0
deprecation warnings.

It's better, the majority of these changes look more readable to me.
also found some docstrings that had formatting / quoting issues.

As the test suite has widespread use of many patterns
that are deprecated, enable SQLALCHEMY_WARN_20 globally
for the test suite but then break the warnings filter
out into a whole list of all the individual warnings
we are looking for. this way individual changesets
can target a specific class of warning, as many of these
warnings will indivdidually affect dozens of files
and potentially hundreds of lines of code.
Many warnings are also resolved here as this
patch started out that way. From this point
forward there should be changesets that target a
subset of the warnings at a time.
For expediency, updates some migration 2.0 docs
for ORM as well.

MariaDB should not run a Sequence if it has optional=True.
Additionally, rework the rules in crud.py to accommodate the
new combination MariaDB brings us, which is a dialect
that supports both cursor.lastrowid, explicit sequences,
*and* no support for returning.

MySQL dialect's server_version_info tuple is now all numeric. String
tokens like "MariaDB" are no longer present so that numeric comparison
works in all cases. The .is_mariadb flag on the dialect should be
consulted for whether or not mariadb was detected. Additionally removed
structures meant to support extremely old MySQL versions 3.x and 4.x;
the minimum MySQL version supported is now version 5.0.2.
In addition, as the "MariaDB" name goes away from server version,
expand upon the change in I330815ebe572b6a9818377da56621397335fa702
to support the name "mariadb" throughout the dialect and test suite
when mariadb-only mode is used. This changes the "name" field
on the MariaDB dialect to "mariadb", which then implies a change
throughout the testing requirements system as well as all the
dialect-specific DDL argument names such as "mysql_engine" is
now specified as "mariadb_engine", etc. Make use of the
recent additions to test suite URL provisioning so that we can
force MariaDB databases to have a "mariadb-only" dialect which
allows us to test this name change fully.
Update documentation to refer to MySQL / MariaDB explicitly
as well as indicating the "mariadb_" prefix used for options.
It seems likely that MySQL and MariaDB version numbers are going to
start colliding at some point so having the "mariadb" name
be available as a totally separate dialect name should give us
some options in this regard.
Currently also includes a date related fix to a test for
the postgresql dialect that was implicitly assuming a
non-UTC timezone

The psycopg2 dialect now defaults to using the very performant
``execute_values()`` psycopg2 extension for compiled INSERT statements,
and also impements RETURNING support when this extension is used. This
allows INSERT statements that even include an autoincremented SERIAL
or IDENTITY value to run very fast while still being able to return the
newly generated primary key values. The ORM will then integrate this
new feature in a separate change.
Implements RETURNING for insert with executemany
Adds support to return_defaults() mode and inserted_primary_key
to support mutiple INSERTed rows, via return_defauls_rows
and inserted_primary_key_rows accessors.
within default execution context, new cached compiler
getters are used to fetch primary keys from rows
inserted_primary_key now returns a plain tuple. this
is not yet a row-like object however this can be
added.
Adds distinct "values_only" and "batch" modes, as
"values" has a lot of benefits but "batch" breaks
cursor.rowcount
psycopg2 minimum version 2.7 so we can remove the
large number of checks for very old versions of
psycopg2
simplify tests to no longer distinguish between
native and non-native json

Added support for "CREATE SEQUENCE" and full :class:`.Sequence` support for
Microsoft SQL Server. This removes the deprecated feature of using
:class:`.Sequence` objects to manipulate IDENTITY characteristics which
should now be performed using ``mssql_identity_start`` and
``mssql_identity_increment`` as documented at :ref:`mssql_identity`. The
change includes a new parameter :paramref:`.Sequence.data_type` to
accommodate SQL Server's choice of datatype, which for that backend
includes INTEGER and BIGINT. The default starting value for SQL Server's
version of :class:`.Sequence` has been set at 1; this default is now
emitted within the CREATE SEQUENCE DDL for all backends.

In 9fca5d827d we attempted to deprecate the "inline=True" flag
and add a generative inline() method, however failed to include
any tests and the method was implemented incorrectly such that
it would get overwritten with the boolean flag immediately.
Rename the internal "inline" flag to "_inline" and add test
support both for the method as well as deprecated support
for the flag, including a fixture addition to assert the expected
value of the flag as it generally does not affect the
actual compiled SQL string.

This builds on cc718cccc0bf8a01abdf4068c7ea4f3 which moved
RowProxy to Row, allowing Row to be more like a named tuple.
- KeyedTuple in ORM is replaced with Row
- ResultSetMetaData broken out into "simple" and "cursor" versions
for ORM and Core, as well as LegacyCursor version.
- Row now has _mapping attribute that supplies full mapping behavior.
Row and SimpleRow both have named tuple behavior otherwise.
LegacyRow has some mapping features on the tuple which emit
deprecation warnings (e.g. keys(), values(), etc). the biggest
change for mapping->tuple is the behavior of __contains__ which
moves from testing of "key in row" to "value in row".
- ResultProxy breaks into ResultProxy and FutureResult (interim),
the latter has the newer APIs. Made available to dialects
using execution options.
- internal reflection methods and most tests move off of implicit
Row mapping behavior and move to row._mapping, result.mappings()
method using future result
- a new strategy system for cursor handling replaces the various
subclasses of RowProxy
- some execution context adjustments. We will leave EC in but
refined things like get_result_proxy() and out parameter handling.
Dialects for 1.4 will need to adjust from get_result_proxy()
to get_result_cursor_strategy(), if they are using this method
- out parameter handling now accommodated by get_out_parameter_values()
EC method. Oracle changes for this. external dialect for
DB2 for example will also need to adjust for this.
- deprecate case_insensitive flag for engine / result, this
feature is not used
mapping-methods on Row are deprecated, and replaced with
Row._mapping.<meth>, including:
row.keys() -> use row._mapping.keys()
row.items() -> use row._mapping.items()
row.values() -> use row._mapping.values()
key in row -> use key in row._mapping
int in row -> use int < len(row)

Revised the formatting for :class:`.StatementError` when stringified. Each
error detail is broken up over multiple newlines instead of spaced out on a
single line. Additionally, the SQL representation now stringifies the SQL
statement rather than using ``repr()``, so that newlines are rendered as is.

Applied on top of a pure run of black -l 79 in
I7eda77fed3d8e73df84b3651fd6cfcfe858d4dc9, this set of changes
resolves all remaining flake8 conditions for those codes
we have enabled in setup.cfg.
Included are resolutions for all remaining flake8 issues
including shadowed builtins, long lines, import order, unused
imports, duplicate imports, and docstring issues.

This is a straight reformat run using black as is, with no edits
applied at all.
The black run will format code consistently, however in
some cases that are prevalent in SQLAlchemy code it produces
too-long lines. The too-long lines will be resolved in the
following commit that will resolve all remaining flake8 issues
including shadowed builtins, long lines, import order, unused
imports, duplicate imports, and docstring issues.
