MySQL Connector/Python 8.0.11 has been released

Dear MySQL users,

MySQL Connector/Python 8.0.11 is the first GA release version of the MySQL Connector Python 8.0 series. This series adds support for the new X DevAPI. 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 http://dev.mysql.com/doc/x-devapi-userguide/en/. For more information about how the X DevAPI is implemented in MySQL Connector/Python, and its usage, see http://dev.mysql.com/doc/dev/connector-python.

Please note that the X DevAPI requires MySQL Server version 5.7.12 or higher with the X Plugin enabled. For general documentation about how to get started using MySQL as a document store, see http://dev.mysql.com/doc/refman/5.7/en/document-store.html.

To download MySQL Connector/Python 8.0.11, see the “General Available
(GA) releases” tab at http://dev.mysql.com/downloads/connector/python/

Enjoy!


Changes in MySQL Connector/Python 8.0.11 (2018-04-19)

     * Functionality Added or Changed

     * Bugs Fixed

   Functionality Added or Changed

     * X DevAPI: Previously, when documents without an _id
       attribute were added to a collection, Connector/Python
       automatically generated _id for them. Now a MySQL 8
       server generates the _id attribute unless a document
       already contains one. The generated IDs resulting from a
       document-add operation can be obtained using the new
       get_generated_ids() method.
       This capability requires a MySQL 8.0 server. Because
       MySQL 5.7 does not support document ID generation, the
       document-add operation returns an error if you do not
       define the _id's.
       Incompatibility: The get_generated_ids() method replaces
       the now removed get_document_ids(). (Bug #27627366)

     * Added NOWAIT and SKIP_LOCKED support to the
       ReadStatement.lock_shared() and
       ReadStatement.lock_exclusive() methods. Example usage:
       lock_exclusive(mysqlx.LockContention.SKIP_LOCKED).

     * The C extension (cext) is now enabled by default, as the
       use_pure option changed from True to False by default.
       If the C extension is not available on the system then
       the Python implementation is used instead, and use_pure
       is set to True.

     * Added the X DevAPI SHA256_MEMORY authentication
       mechanism.
       Example mysqlx.get_session() usages: ?auth=SHA256_MEMORY
       via a connection string, "auth":
       mysqlx.Auth.SHA256_MEMORY via a dictionary, or
       auth=mysqlx.Auth.SHA256_MEMORY via method parameters.

   Bugs Fixed

     * Warnings are now stored as a list of dictionaries instead
       of a list of tuples. In other words, get_warnings()
       returns the likes of [{"level": _level_, "code": _code_,
       "msg": _msg_}] instead of [(_level_, _code_, _msg_))].
       (Bug #27639119)

     * The mapped MySQL Server error codes were synced with
       MySQL Server 8.0.11. (Bug #27634885)

     * Removed upsert functionality from InsertStatement as it
       can only be used by collections, so upsert remains
       available to AddStatement. (Bug #27589450)

     * MySQLConverter.escape() functionality was added to
       create_schema()'s count mechanism. (Bug #27528842)

     * When using prepared statements, string columns were
       returned as bytearrays instead of strings. The returned
       value is now a string decoded using the connection's
       charset (defaults to 'utf8'), or as a bytearray if this
       conversion fails. (Bug #27364914)

     * The result from JSON_TYPE() was returned as a bytearray
       instead of a string. The returned value is now a string
       decoded using the connection's charset (defaults to
       'utf8'), or as a bytearray if this conversion fails. (Bug
       #24948205, Bug #83516)

     * JSON integer values were cast to bytes in Python instead
       of integers. (Bug #24948186, Bug #83513)
