Build out new declarative systems; deprecate mapper()

2020-09-10T21:53:53+00:00

The ORM Declarative system is now unified into the ORM itself, with new
import spaces under ``sqlalchemy.orm`` and new kinds of mappings.  Support
for decorator-based mappings without using a base class, support for
classical style-mapper() calls that have access to the declarative class
registry for relationships, and full integration of Declarative with 3rd
party class attribute systems like ``dataclasses`` and ``attrs`` is now
supported.

Update select usage to use the new 1.4 format

2020-09-08T21:13:48+00:00

This change includes mainly that the bracketed use within
select() is moved to positional, and keyword arguments are
removed from calls to the select() function.  it does not
yet fully address other issues such as keyword arguments passed
to the table.select().

Additionally, allows False / None to both be considered
as "disable" for all of select.correlate(), select.correlate_except(),
query.correlate(), which establishes consistency with
passing of ``False`` for the legact select(correlate=False)
argument.

Emit v2.0 deprecation warning for "implicit autocommit"

2020-08-28T20:32:05+00:00

"Implicit autocommit", which is the COMMIT that occurs when a DML or DDL
statement is emitted on a connection, is deprecated and won't be part of
SQLAlchemy 2.0.   A 2.0-style warning is emitted when autocommit takes
effect, so that the calling code may be adjusted to use an explicit
transaction.

As part of this change, DDL methods such as
:meth:`_schema.MetaData.create_all` when used against a
:class:`_engine.Engine` or :class:`_engine.Connection` will run the
operation in a BEGIN block if one is not started already.

The MySQL and MariaDB dialects now query from the information_schema.tables
system view in order to determine if a particular table exists or not.
Previously, the "DESCRIBE" command was used with an exception catch to
detect non-existent,  which would have the undesirable effect of emitting a
ROLLBACK on the connection. There appeared to be legacy encoding issues
which prevented the use of "SHOW TABLES", for this, but as MySQL support is
now at 5.0.2  or above due to :ticket:`4189`, the information_schema tables
are now available in all cases.

  expression match like function.
* :meth:`~.ColumnOperators.regexp_replace` implementing a regular
  expression string replace function.
