MySQL Connector/Python v0.1.3-devel is now available for download from Launchpad.org. Please note that this is a development (i.e. alpha, unstable, ..) release and we welcome everyone to test and report problems.

Highlights for this v0.1.3-devel:

• Important memory leak fixed when closing cursors.
• Warnings can now be raised as exceptions.
• Fixing unicode usage and broken error message when MySQL chops them
• Client flags can now be set correctly when connecting
• Conversion fixes for BIT/YEARSET and Python to DATE/DATETIME
• Adding MySQL Client Errors and raising better exceptions based on errno.

Enjoy!

Using SQLAlchemy unit test cases to further develop MySQL Connector/Python. It's probably debatable whether that's a good method or just lame. But it sure helps lots!

We've been pushing some code past days that makes Connector/Python almost pass all tests. Well, 4% is still failing, but I'm confident that in a few most problems will be dealt with. I had to make some changes to the SQLAlchemy v0.6 dialect as well, and some test cases had to be corrected. Hopefully those corrections will also go in the SQLAlchemy trunk later on.

Something to keep you warm during cold winter nights, or cool during hot summer days: a chessboard in MySQL!

Note: You should see chess pieces here below. If not, you're not watching it using UTF-8, or get yourself a good browser!

CREATE TABLE `chessboard` (
  `x` tinyint unsigned NOT NULL,
  `a` enum('','♔','♕','♖','♗','♘','♙','♚','♛','♜','♝','♞','♟'),
  `b` enum('','♔','♕','♖','♗','♘','♙','♚','♛','♜','♝','♞','♟'),
  `c` enum('','♔','♕','♖','♗','♘','♙','♚','♛','♜','♝','♞','♟'),
  `d` enum('','♔','♕','♖','♗','♘','♙','♚','♛','♜','♝','♞','♟'),
  `e` enum('','♔','♕','♖','♗','♘','♙','♚','♛','♜','♝','♞','♟'),
  `f`

Here is two small examples showing the wonderful world of character sets and unicode using MySQL Connector/Python (using 0.1.2-devel and up) in both Python v2.x and v3.1.

The following table will be used with default character set latin7, i.e. ISO-8859-13. Just setting it to UTF-8 would be bit boring!

CREATE TABLE `latin7test` (
  `c1` varchar(60) DEFAULT NULL
) DEFAULT CHARSET=latin7

Things to note for the code listed below are:

• We're using charset='latin7' as connection option. This is important!
• We set use_unicode=True so the results coming from MySQL are encoded to unicode. For testing, we disable this

MySQL Connector/Python 0.1.2-devel is a quick follow-up release for 0.1.1 fixing a few problems around character sets and unicode.

You can download Connector/Python from LaunchPad.

Release notes for MySQL Connector/Python 0.1.2-devel

o Fixing unicode usage for both Python 2.4+ and 3.1
  * Setting 'use_unicode' at connection time is now
    working.
  * conversion.py: removing regular expression for
    quoting backslashes.
  * Adding test case for bug lp:499410
  
  Py3k specific:
  * Strings from MySQL are decoded to the given character
    when use_unicode is false
  * The statement is encoded just before sending it to the
    MySQL server.

The second development release of MySQL Connector/Python comes with support for Python v3.1!

I thought of making two distributions of MySQL Connector/Python, but then it would have been messy with versions and packaging. So what you get now is 2-in-1 and the installation script should be smart enough to figure it out.

Please, if you find any issues, bugs or have suggestions: report them here https://bugs.launchpad.net/myconnpy

Release notes

Added Python v3.1 support
* The subdirectory/module py3k/ contains Connector/Python compatible
  with Python v3.1.1.
* setup.py will install the correct Connector/Python

Today we're releasing MySQL Connector/Python 0.1.0-devel. This is the first in a serie of development snapshots aimed to get more people trying it out and reporting problems. This is not a production-ready release, but it should work on all Unices and Windows which has Python 2.4 or later installed. (No, no Py3K, yet!)

You can download it from Launchpad: there is a .tar.gz and .zip

There will be documentation and tutorial, but installation is as easy as pie (pun intended):

 shell> tar xzf mysql-connector-python-0.1.0-devel.tar.gz
 shell> cd mysql-connector-python-0.1.0-devel
 shell> python ./setup.py install

I'm currently planning a first 'alpha' release of MySQL Connector/Python, but I'm now doubting whether the naming and installation of the module is actually good.

Currently, the module lives, in site-packages/mysql/connector/, or import mysql.connector. Since this is an official MySQL, sorry, Sun Microsystems, project, I thought that the 'parent' module mysql would be good enough.

But is it? Would it break your modules with the same name?

The idea was to make more tools for Python and have them all under the mysql module, but maybe we need a smarter name for this? Maybe sunmysql/connector?
