A special extended edition of Tech Messages for 2010-04-15 through 2010-04-24:
I’ve recently had the pleasure of reading “Python Testing: An easy and convenient approach to testing your python projects” from Packt Publishing. It’s been a quick read but a solid set of instructions on the different methods for the subject.
The book starts out very quickly with details about the various methods that are available, the means of automation for testing, and of course the environment you’d want to be in for working on the subjects that the book covers. It then, in the second chapter, moves into the guts of testing by describing the basics of doctest via syntax and some simple examples, and then moves on to a real world example via the AVL tree. It’s all very basic testing until chapter three where the author gets into unit testing, …
[Read more]I’ve been wanting to write a backup script for a while now that does the following: reads the partition information for the directory that you are backing up into and computes the used/available/percentage-available space. Then it reads the total data size from the MySQL tables and ensures that you have enough space on disk (for [...]
I’m pleased to announce the first release of Kontrollcomm – “The Server Command Automation Interface” is a web-based application that automates remote command execution on linux and unix based servers. There are three main areas of the application: Hosts, Templates, and Commands. The use is very simple: all of your hosts are setup in the [...]
Most of this stuff is not PHP specific, and Python or Ruby or Java or .NET developers can use the tools in this talk.

Just a quick notice to let everyone know that there is a new version of Kontrollkit available. There are two new scripts included as well as some good updates to the my.cnf files. You can download the new version here: http://kontrollsoft.com/software-downloads kt-mysql-systemcheck – generates a report for point-in-time system status that is useful for troubleshooting MySQL [...]
This is a simple matter with a simple solution that might help someone save time and confusion. Emacs wasn’t coloring my comments correctly so I went ahead and had it change them to red-italic. If you are having similar issues you can drop the following into your home directory’s .emacs file. Enjoy. Keep in mind that if you are using emacs in a terminal session as opposed to the X-server gui then you will not see the italics.

Looking around on Google for a webpage test script returns a lot of results. Some of them are useful, some are not. In particular, for Python, the scripts on the first page of results are minimal and lacking a useful copy and paste / ready to go script that will answer the question “is my webpage available?”. So I decided to write a quick one that will give you the return code and email you as an alert if the page does not return with a 200 code (successful). You can find the script here. Update: the webserver was trying to execute the script as a .py file so I just changed it to .txt – for it to work you will want to change the .txt extension to a .py extension after you download it.
If you are familiar with Python scripting, this script could easily be modified to post to a form so that you can test a MySQL transaction (or other transactional DB) …
[Read more]Few days ago, the folks at SQLAlchemy pushed some proposed modification to the MySQL Connector/Python dialect. Before this patch, previous report yielded 72 errors and 11 failures. Now we got down to 9 errors, but the failures are still lingering. Is this an improvement? Yes and no, failures should go down, but there are some SQLAlchemy tests I just can't figure out, yet.. clues are welcome!
Here are some detailed results which also included MySQLdb and oursql. I used SQLAlchemy revision 6788 (i.e. from …

At Fosdem
2010, already two weeks ago, I had the pleasure of hearing
Geert van
der Kelen explain the work he has been doing on connecting
MySQL and
Python. I don't
know anything about Python, but anybody that has the courage,
perseverance and coding skills to create an implementation of the
the MySQL wire protocol from scratch is a class-A programmer in
my book. So, I encourage everyone that needs MySQL connectivity
for Python programs to check out Geert's brainchild, MySQL
Connector/Python.
In relation to MySQL Connector/Python, I just read a post from Geert …
