Add reflection for Identity columns

2020-09-28T22:11:12+00:00

Added support for reflecting "identity" columns, which are now returned
as part of the structure returned by :meth:`_reflection.Inspector.get_columns`.
When reflecting full :class:`_schema.Table` objects, identity columns will
be represented using the :class:`_schema.Identity` construct.

Fixed compilation error on oracle for sequence and identity column
``nominvalue`` and ``nomaxvalue`` options that require no space in them.

Improved test compatibility with oracle 18.

As part of the support for reflecting :class:`_schema.Identity` objects,
the method :meth:`_reflection.Inspector.get_columns` no longer returns
``mssql_identity_start`` and ``mssql_identity_increment`` as part of the
``dialect_options``. Use the information in the ``identity`` key instead.

The mssql dialect will assume that at least MSSQL 2005 is used.
There is no hard exception raised if a previous version is detected,
but operations may fail for older versions.

Merge "Pass all pool parameters in recreate()"

2020-09-14T18:25:51+00:00

Pass all pool parameters in recreate()

2020-09-14T15:36:31+00:00

The following pool parameters were not being propagated to the new pool
created when :meth:`_engine.Engine.dispose` were called: ``pre_ping``,
``use_lifo``.  Additionally the ``recycle`` and ``reset_on_return``
parameters were not propagated for the :class:`_engine.AssertionPool`
class.  These issues have been fixed.

Adapt event exec_once_mutex to asyncio

2020-09-14T12:04:09+00:00

The pool makes use of a threading.Lock() for the
"first_connect" event.  if the pool is async make sure this
is a greenlet-adapted asyncio lock.

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.

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.

error message for Lookup

2020-08-17T14:34:22+00:00

Thr proposed change will provide the user with the target Enum Class name as well as up to four possible enum values when a LookupError is raised in the Enum Class.

A user requested that the enum name and possible values are included to the LookupError message to make debugging easier. The criteria included using ellipses for Enums containing more than four values and using ellipses for enum values that were greater than a certain number of characters (for this resolution the limit is 11 characters).

This pull request is:

- [ ] A documentation / typographical error fix
	- Good to go, no issue or tests are needed
- [X ] A short code fix
	- please include the issue number, and create an issue if none exists, which
	  must include a complete example of the issue.  one line code fixes without an
	  issue and demonstration will not be accepted.
	- Please include: `Fixes: #` in the commit message
	- please include tests.   one line code fixes without tests will not be accepted.
- [ ] A new feature implementation
