Dear MySQL users, MySQL Connector/Python 2.1.1-alpha is the first alpha version of 2.1 release series of the pure Python database driver for MySQL. It is intended to introduce users to the new features. This release is not feature complete but it should be stable enough for users to understand the new features and how we expect them to work. As is the case with all non-GA releases, it should not be used in any production environment. MySQL Connector/Python version 2.1.1-alpha is compatible with MySQL Server versions 5.5 and greater. Python 2.6 and greater as well as Python 3.3 and greater are supported. Python 2.4, 2.5 and 3.1, 3.2 are not supported. MySQL Connector/Python 2.1.1-alpha is available for download from: http://dev.mysql.com/downloads/connector/python/#downloads The ChangeLog file included in the distribution contains a brief summary of changes in MySQL Connector/Python 2.1.1. For a more complete list of changes, see below or online at: http://dev.mysql.com/doc/relnotes/connector-python/en/ ========================================================================= Changes in MySQL Connector/Python 2.1.1 (2015-02-23) C Extension Notes * MySQL Connector/Python distributions now are available that include a C Extension that interfaces with the MySQL C client library. For queries that return large result sets, using the C Extension can improve performance compared to a "pure Python" implementation of the MySQL client/server protocol. For binary Connector/Python distributions, some packaging types have a single distribution file that includes the pure-Python Connector/Python code together with the C Extension. (Windows MSI and OS X Disk Image packages fall into this category.) Other packaging types have two related distribution files: One that includes the pure-Python Connector/Python code, and one that includes only the C Extension. For packaging types that have separate distribution files, install both distributions if you want to use the C Extension. The two files have related names, the difference being that the one that contains the C Extension has "cext" in the distribution file name. Source distributions include both the pure-Python code and the C Extension, and distribution names do not contain "cext". Instead, availability of the C Extension is determined by whether you compile the distribution with the --with-mysql-capi option. Packages for Connector/Python with the C Extension are available at the Connector/Python download site (http://dev.mysql.com/downloads/connector/python/). For installation instructions, see Connector/Python Installation (http://dev.mysql.com/doc/connector-python/en/connector-python-installation.html). For information about using the C Extension, see The Connector/Python C Extension (http://dev.mysql.com/doc/connector-python/en/connector-python-cext.html). For Connector/Python installations that support the C Extension, the use_pure connection argument to connect() controls whether to use the extension. If use_pure is True (the default), the connection uses pure Python. If use_pure is False, the connection uses the C Extension. It is also possible to use the C Extension directly, by importing the _mysql_connector module rather than the mysql.connector module. See The _mysql_connector C Extension Module (http://dev.mysql.com/doc/connector-python/en/connector-python-cext-module.html). Bugs Fixed * With mysql.connector.django as the engine, the python manage.py inspectdb command failed with an "Unread result found" error. (Bug #20022533) * If the pool_size and pool_name connection arguments were specified using the option file (as opposed to being passed explicitly to the connect call), the pooled connection was successfully created, but an exception was raised when closing it. (Bug #19549363) * The Django backend raised an exception when converting "0000-00-00 00:00:00" to None. (Bug #73940, Bug #19667984) * The type_code in cursor.description did not compare equal to any of the type objects defined in mysql.connector.dbapi. (Bug #73798, Bug #19584051) * Data corruption occurred when inserting sufficiently large data in a table with a TEXT type column using prepared statements, due to incorrect encoding of the data length while sending the prepared statement packet. (Bug #73690, Bug #19522948) * When the character set was binary, character set conversion could occur. Conversion is no longer done and binary data is returned as is. (Bug #71909, Bug #19500097) Documentation -------------------- Online:http://dev.mysql.com/doc/connector-python/en/index.html The source distribution includes the manual in various formats under the docs/ folder. Reporting Bugs -------------------- We welcome and appreciate your feedback and bug reports: http://bugs.mysql.com/ Enjoy ! On Behalf of the MySQL RE team at Oracle
