Subject:MySQL Connector/Python 8.0.13 has been released
View as plain text  
Dear MySQL users,

MySQL Connector/Python 8.0.13 is the third GA release version of the
MySQL Connector Python 8.0 series. This series adds support for Python
3.7.  The X DevAPI enables application developers to write code that
combines the strengths of the relational and document models using a
modern, NoSQL-like syntax that does not assume previous experience
writing traditional SQL.

To learn more about how to write applications using the X DevAPI, see For more information
about how the X DevAPI is implemented in MySQL Connector/Python, and its
usage, see

For general documentation about how to get started using MySQL
as a document store, see

(GA) releases" tab at


Changes in MySQL Connector/Python 8.0.13 (2018-10-22, General Availability)

Functionality Added or Changed

      * Added Python 3.7 support. (Bug #27081809, Bug #87818)

      * To go with the existing mysqlx.get_session(conn_str)
        method, a new mysqlx.get_client(conn_str, options)
method was
        added that creates a connection pool handler that
provides a
        get_session() method to create and retrieve
connections from the
        pool. The collection pooling options are:

           + enabled: enables or disables
connection pooling;
             boolean and defaults
to true.

           + max_size: maximum number of
connections available in
             the pool; positive
integer and defaults to 25.

           + max_idle_time: maximum number of
milliseconds a
             connection can be idle
in the queue before being
             closed; integer >=
0 and defaults to 0 (infinite).

           + queue_timeout: maximum number of
milliseconds a
             request will wait for
a connection to become
             available; integer
>= 0 and defaults to 0
             This is different than
connect_timeout that's used
             for non-pooling. In a
pooling scenario there are
             already connections in
the pool, so queue_timeout
             controls how long to
wait for a connection in the
        Example usage:
client = mysqlx.get_client(
     'host': 'localhost',
     'port': 33060,
     'user': 'mike',
     'password': 'password'
     { pooling: {
         enabled: true,
         max_idle_time: 5000,
         max_size: 25,
         queue_timeout: 20000

        Closing a session attached to the pool makes the
        connection available in the pool for subsequent
        get+session() calls, while closing (destroying) the
        effectively closes all server connections.

      * Added a connection-timeout connection timeout query
        parameter. This defines the length of time
        the client waits for a MySQL server to become
        in the given network addresses. It was added to both
        mysqlx.get_session() (non-pooling sessions) and
        mysqlx.get_client() (pooling sessions) interfaces.
        option defaults to 10000 (10 seconds). The value 0
        disables the timeout so the client will wait until
        underlying socket (platform dependent) times out.
        Example usages:

        In a multi-host scenario, the connect-timeout value
applies to
        each individual host.

Bugs Fixed

      * On Windows, the 32-bit MSI failed to install. The
        registry key path was updated to allow the CEXT
        check to execute and pass. (Bug #28395599, Bug

      * Subsequent collection.add() method calls would leak
        memory if the C extension was enabled. (Bug

      * Missing bind() parameters could cause an unclear error
        message or unexpectedly halt. (Bug #28037275)

      * The username and password fields are now quoted to allow
        special characters when making X DevAPI connections.
        (Bug #27528819, Bug #89614)

Enjoy and thanks for the support!
