Replace c extension with cython versions.

2021-12-17T20:29:05+00:00

Re-implement c version immutabledict / processors / resultproxy / utils with cython.
Performance is in general in par or better than the c version
Added a collection module that has cython version of OrderedSet and IdentitySet

Added a new test/perf file to compare the implementations.
Run ``python test/perf/compiled_extensions.py all`` to execute the comparison test.

include InterfaceError for mariadb disconnect check

2021-12-16T14:17:04+00:00

Corrected the error classes inspected for the "is_disconnect" check for the
``mariadbconnector`` dialect, which was failing for disconnects that
occurred due to common MySQL/MariaDB error codes such as 2006; the DBAPI
appears to currently use the ``mariadb.InterfaceError`` exception class for
disconnect errors such as error code 2006, which has been added to the list
of classes checked.

For the current "real reconnect test", shutting down the mariadb
connection from the client side produces
ProgrammingError("Connection isn't valid anymore") which we also
continue to intercept.

use the options from the cached statement for propagate_options

2021-12-12T19:23:03+00:00

Fixed caching-related issue where the use of a loader option of the form
``lazyload(aliased(A).bs).joinedload(B.cs)`` would fail to result in the
joinedload being invoked for runs subsequent to the query being cached, due
to a mismatch for the options / object path applied to the objects loaded
for a query with a lead entity that used ``aliased()``.

Add async_engine_from_config()

2021-12-10T16:20:31+00:00

Added :func:`_asyncio.async_engine_config` function to create
an async engine from a configuration dict.  This otherwise
behaves the same as :func:`_sa.engine_from_config`.

Update references to tables in PostgreSQL documentation

2021-12-10T13:27:19+00:00

Since the table numbers change from one version of PostgreSQL to
the next, refer to the tables by name rather than by number.
