        Construct a Pool.

        :param creator: a callable function that returns a DB-API
          connection object.  The function will be called with
          parameters.

        :param recycle: If set to a value other than -1, number of
          seconds between connection recycling, which means upon
          checkout, if this timeout is surpassed the connection will be
          closed and replaced with a newly opened connection. Defaults to -1.

        :param logging_name:  String identifier which will be used within
          the "name" field of logging records generated within the
          "sqlalchemy.pool" logger. Defaults to a hexstring of the object's
          id.

        :param echo: if True, the connection pool will log
         informational output such as when connections are invalidated
         as well as when connections are recycled to the default log handler,
         which defaults to ``sys.stdout`` for output..   If set to the string
         ``"debug"``, the logging will include pool checkouts and checkins.

         The :paramref:`_pool.Pool.echo` parameter can also be set from the
         :func:`_sa.create_engine` call by using the
         :paramref:`_sa.create_engine.echo_pool` parameter.

         .. seealso::

             :ref:`dbengine_logging` - further detail on how to configure
             logging.

        :param reset_on_return: Determine steps to take on
         connections as they are returned to the pool, which were
         not otherwise handled by a :class:`_engine.Connection`.
         Available from :func:`_sa.create_engine` via the
         :paramref:`_sa.create_engine.pool_reset_on_return` parameter.

         :paramref:`_pool.Pool.reset_on_return` can have any of these values:

         * ``"rollback"`` - call rollback() on the connection,
           to release locks and transaction resources.
           This is the default value.  The vast majority
           of use cases should leave this value set.
         * ``"commit"`` - call commit() on the connection,
           to release locks and transaction resources.
           A commit here may be desirable for databases that
           cache query plans if a commit is emitted,
           such as Microsoft SQL Server.  However, this
           value is more dangerous than 'rollback' because
           any data changes present on the transaction
           are committed unconditionally.
         * ``None`` - don't do anything on the connection.
           This setting may be appropriate if the database / DBAPI
           works in pure "autocommit" mode at all times, or if
           a custom reset handler is established using the
           :meth:`.PoolEvents.reset` event handler.

         * ``True`` - same as 'rollback', this is here for
           backwards compatibility.
         * ``False`` - same as None, this is here for
           backwards compatibility.

         For further customization of reset on return, the
         :meth:`.PoolEvents.reset` event hook may be used which can perform
         any connection activity desired on reset.

         .. seealso::

            :ref:`pool_reset_on_return`

            :meth:`.PoolEvents.reset`

        :param events: a list of 2-tuples, each of the form
         ``(callable, target)`` which will be passed to :func:`.event.listen`
         upon construction.   Provided here so that event listeners
         can be assigned via :func:`_sa.create_engine` before dialect-level
         listeners are applied.

        :param dialect: a :class:`.Dialect` that will handle the job
         of calling rollback(), close(), or commit() on DBAPI connections.
         If omitted, a built-in "stub" dialect is used.   Applications that
         make use of :func:`_sa.create_engine` should not use this parameter
         as it is handled by the engine creation strategy.

        :param pre_ping: if True, the pool will emit a "ping" (typically
         "SELECT 1", but is dialect-specific) on the connection
         upon checkout, to test if the connection is alive or not.   If not,
         the connection is transparently re-connected and upon success, all
         other pooled connections established prior to that timestamp are
         invalidated.     Requires that a dialect is passed as well to
         interpret the disconnection error.

y	)<0F>ManagesConnectiona3Common base for the two connection-management interfaces
    :class:`.PoolProxiedConnection` and :class:`.ConnectionPoolEntry`.

    These two objects are typically exposed in the public facing API
    via the connection pool event hooks, documented at :class:`.PoolEvents`.

    r,<00>Optional[DBAPIConnection]r=<00>
Optional[Any]<5D>driver_connectionc<01><00>t<00><00>)a<>Info dictionary associated with the underlying DBAPI connection
        referred to by this :class:`.ManagesConnection` instance, allowing
        user-defined data to be associated with the connection.

        The data in this dictionary is persistent for the lifespan
        of the DBAPI connection itself, including across pool checkins
        and checkouts.  When the connection is invalidated
        and replaced with a new one, this dictionary is cleared.

        For a :class:`.PoolProxiedConnection` instance that's not associated
        with a :class:`.ConnectionPoolEntry`, such as if it were detached, the
        attribute returns a dictionary that is local to that
        :class:`.ConnectionPoolEntry`. Therefore the
        :attr:`.ManagesConnection.info` attribute will always provide a Python
        dictionary.

<00><00>0"<22>#<23>#r-c<01><00>t<00><00>)a<>Persistent info dictionary associated with this
        :class:`.ManagesConnection`.

        Unlike the :attr:`.ManagesConnection.info` dictionary, the lifespan
        of this dictionary is that of the :class:`.ConnectionPoolEntry`
        which owns it; therefore this dictionary will persist across
        reconnects and connection invalidation for a particular entry
        in the connection pool.

        For a :class:`.PoolProxiedConnection` instance that's not associated
        with a :class:`.ConnectionPoolEntry`, such as if it were detached, the
        attribute returns None. Contrast to the :attr:`.ManagesConnection.info`
        dictionary which is never None.

    connection on behalf of a :class:`_pool.Pool` instance.

    The :class:`.ConnectionPoolEntry` object represents the long term
    maintainance of a particular connection for a pool, including expiring or
    invalidating that connection to have it replaced with a new one, which will
    continue to be maintained by that same :class:`.ConnectionPoolEntry`
    instance. Compared to :class:`.PoolProxiedConnection`, which is the
    short-term, per-checkout connection manager, this object lasts for the
    lifespan of a particular "slot" within a connection pool.

    The :class:`.ConnectionPoolEntry` object is mostly visible to public-facing
    API code when it is delivered to connection pool event hooks, such as
    :meth:`_events.PoolEvents.connect` and :meth:`_events.PoolEvents.checkout`.

    .. versionadded:: 2.0  :class:`.ConnectionPoolEntry` provides the public
       facing interface for the :class:`._ConnectionRecord` internal class.

<EFBFBD>Zy)rOaA connection-like adapter for a :pep:`249` DBAPI connection, which
    includes additional methods specific to the :class:`.Pool` implementation.

    :class:`.PoolProxiedConnection` is the public-facing interface for the
    internal :class:`._ConnectionFairy` implementation object; users familiar
    with :class:`._ConnectionFairy` can consider this object to be equivalent.

    .. versionadded:: 2.0  :class:`.PoolProxiedConnection` provides the public-
       facing interface for the :class:`._ConnectionFairy` internal class.

        This means that the connection will no longer be returned to the
        pool when closed, and will instead be literally closed.  The
        associated :class:`.ConnectionPoolEntry` is de-associated from this
        DBAPI connection.

        Note that any overall connection limiting constraints imposed by a
        Pool implementation may be violated after a detach, as the detached
        connection is removed from the pool's knowledge and control.

<00><00>"<22>#<23>#r-c<01><00>t<00><00>)a$Release this connection back to the pool.

        The :meth:`.PoolProxiedConnection.close` method shadows the
        :pep:`249` ``.close()`` method, altering its behavior to instead
        :term:`release` the proxied connection back to the connection pool.

        Upon release to the pool, whether the connection stays "opened" and
        pooled in the Python process, versus actually closed out and removed
        from the Python process, is based on the pool implementation in use and
        its configuration and current state.

    support.

    This is an internal object used by the :class:`_pool.Pool` implementation
    to provide context management to a DBAPI connection delivered by
    that :class:`_pool.Pool`.   The public facing interface for this class
    is described by the :class:`.PoolProxiedConnection` class.  See that
    class for public API details.

    The name "fairy" is inspired by the fact that the
    :class:`._ConnectionFairy` object's lifespan is transitory, as it lasts
    only for the length of a specific DBAPI connection being checked out from
    the pool, and additionally that as a transparent proxy, it is mostly
    invisible.

 								        Construct a Pool.
 								        :param creator: a callable function that returns a DB-API
 								          connection object.  The function will be called with
 								          parameters.
 								        :param recycle: If set to a value other than -1, number of
 								          seconds between connection recycling, which means upon
 								          checkout, if this timeout is surpassed the connection will be
 								          closed and replaced with a newly opened connection. Defaults to -1.
 								        :param logging_name:  String identifier which will be used within
 								          the "name" field of logging records generated within the
 								          "sqlalchemy.pool" logger. Defaults to a hexstring of the object's
 								          id.
 								        :param echo: if True, the connection pool will log
 								         informational output such as when connections are invalidated
 								         as well as when connections are recycled to the default log handler,
 								         which defaults to ``sys.stdout`` for output..   If set to the string
 								         ``"debug"``, the logging will include pool checkouts and checkins.
 								         The :paramref:`_pool.Pool.echo` parameter can also be set from the
 								         :func:`_sa.create_engine` call by using the
 								         :paramref:`_sa.create_engine.echo_pool` parameter.
 								         .. seealso::
 								             :ref:`dbengine_logging` - further detail on how to configure
 								             logging.
 								        :param reset_on_return: Determine steps to take on
 								         connections as they are returned to the pool, which were
 								         not otherwise handled by a :class:`_engine.Connection`.
 								         Available from :func:`_sa.create_engine` via the
 								         :paramref:`_sa.create_engine.pool_reset_on_return` parameter.
 								         :paramref:`_pool.Pool.reset_on_return` can have any of these values:
 								         * ``"rollback"`` - call rollback() on the connection,
 								           to release locks and transaction resources.
 								           This is the default value.  The vast majority
 								           of use cases should leave this value set.
 								         * ``"commit"`` - call commit() on the connection,
 								           to release locks and transaction resources.
 								           A commit here may be desirable for databases that
 								           cache query plans if a commit is emitted,
 								           such as Microsoft SQL Server.  However, this
 								           value is more dangerous than 'rollback' because
 								           any data changes present on the transaction
 								           are committed unconditionally.
 								         * ``None`` - don't do anything on the connection.
 								           This setting may be appropriate if the database / DBAPI
 								           works in pure "autocommit" mode at all times, or if
 								           a custom reset handler is established using the
 								           :meth:`.PoolEvents.reset` event handler.
 								         * ``True`` - same as 'rollback', this is here for
 								           backwards compatibility.
 								         * ``False`` - same as None, this is here for
 								           backwards compatibility.
 								         For further customization of reset on return, the
 								         :meth:`.PoolEvents.reset` event hook may be used which can perform
 								         any connection activity desired on reset.
 								         .. seealso::
 								            :ref:`pool_reset_on_return`
 								            :meth:`.PoolEvents.reset`
 								        :param events: a list of 2-tuples, each of the form
 								         ``(callable, target)`` which will be passed to :func:`.event.listen`
 								         upon construction.   Provided here so that event listeners
 								         can be assigned via :func:`_sa.create_engine` before dialect-level
 								         listeners are applied.
 								        :param dialect: a :class:`.Dialect` that will handle the job
 								         of calling rollback(), close(), or commit() on DBAPI connections.
 								         If omitted, a built-in "stub" dialect is used.   Applications that
 								         make use of :func:`_sa.create_engine` should not use this parameter
 								         as it is handled by the engine creation strategy.
 								        :param pre_ping: if True, the pool will emit a "ping" (typically
 								         "SELECT 1", but is dialect-specific) on the connection
 								         upon checkout, to test if the connection is alive or not.   If not,
 								         the connection is transparently re-connected and upon success, all
 								         other pooled connections established prior to that timestamp are
 								         invalidated.     Requires that a dialect is passed as well to
 								         interpret the disconnection error.

 								        The :meth:`.PoolProxiedConnection.close` method shadows the
 								        :pep:`249` ``.close()`` method, altering its behavior to instead
 								        :term:`release` the proxied connection back to the connection pool.
 								        Upon release to the pool, whether the connection stays "opened" and
 								        pooled in the Python process, versus actually closed out and removed
 								        from the Python process, is based on the pool implementation in use and
 								        its configuration and current state.

 								    pool events that may not always have the :class:`._ConnectionFairy`
 								    available.

 								    support.
 								    This is an internal object used by the :class:`_pool.Pool` implementation
 								    to provide context management to a DBAPI connection delivered by
 								    that :class:`_pool.Pool`.   The public facing interface for this class
 								    is described by the :class:`.PoolProxiedConnection` class.  See that
 								    class for public API details.
 								    The name "fairy" is inspired by the fact that the
 								    :class:`._ConnectionFairy` object's lifespan is transitory, as it lasts
 								    only for the length of a specific DBAPI connection being checked out from
 								    the pool, and additionally that as a transparent proxy, it is mostly
 								    invisible.
 								    .. seealso::
