guard against unexpected weakref cleanups

2021-07-16T15:34:13+00:00

Added some guards against ``KeyError`` in the event system to accommodate
the case that the interpreter is shutting down at the same time
:meth:`_engine.Engine.dispose` is being called, which would cause stack
trace warnings.

Genericize setinputsizes and support pyodbc

2020-10-16T18:28:04+00:00

Reworked the "setinputsizes()" set of dialect hooks to be correctly
extensible for any arbirary DBAPI, by allowing dialects individual hooks
that may invoke cursor.setinputsizes() in the appropriate style for that
DBAPI.   In particular this is intended to support pyodbc's style of usage
which is fundamentally different from that of cx_Oracle.  Added support
for pyodbc.

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.

Add new "exec_once_unless_exception" system; apply to dialect.initialize

2019-08-18T14:41:52+00:00

Fixed an issue whereby if the dialect "initialize" process which occurs on
first connect would encounter an unexpected exception, the initialize
process would fail to complete and then no longer attempt on subsequent
connection attempts, leaving the dialect in an un-initialized, or partially
initialized state, within the scope of parameters that need to be
established based on inspection of a live connection.   The "invoke once"
logic in the event system has been reworked to accommodate for this
occurrence using new, private API features that establish an "exec once"
hook that will continue to allow the initializer to fire off on subsequent
connections, until it completes without raising an exception. This does not
impact the behavior of the existing ``once=True`` flag within the event
system.
