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.

Add more docs for populate_existing(); link with_for_update

2020-09-10T16:15:16+00:00

The populate_existing() method is actually changing
to be an execution option, however it has almost no
mention in the narrative docs so add docs in terms of the
1.x version first, including that we mention you almost
definitely want to use this method if you are also using
with_for_update().

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.

Create connection characteristics API; implement postgresql flags

2020-09-08T15:16:53+00:00

Added support for PostgreSQL "readonly" and "deferrable" flags for all of
psycopg2, asyncpg and pg8000 dialects.   This takes advantage of a newly
generalized version of the "isolation level" API to support other kinds of
session attributes set via execution options that are reliably reset
when connections are returned to the connection pool.
