Using the MySQL Test Suite

MySQL provides two different tools to test the MySQL Server with SQL statements. One is mysqltest and in 5.1 mysqlslap. Both of these tools have quite different purposes. This is a quick review of the usage of mysqltest.

Current Usage

Under Linux deploys, the README in the mysql-test directory gives you all the information you need to know to run.

To run the full test suite.

cd /opt/mysql/mysql-test
 ./mysql-test-run

Rather easy, it does take some time, and I was surprised to find a number of tests marked as ’skipped’. The general purpose of having tests in a product is to provide coverage of software functionality, and tests should always be forward …

Guidelines for managing embedded external project dependencies

I’ve yet to find any Java project that doesn’t have dependancies on some other Open Source external libraries. I’ve yet to find a Java project that manages these external dependencies appropiately for support and integration at an enterprise level.

As with most projects, understanding an applying sound principles that scale will help you at a later date, and generally the cost of implementation is minimual at the start, but of course becomes more expensive when it’s really needed. The classic case is Version Control. For over 10 years, even on small single developer projects, I’ve used Version Control, it should be taught at university as an introduction to good programming design, it would greatly benefit software development and maintenance.

Back onto the topic of hand. Let’s use a moderate Java Web Based application, and for the purposes of this discussion the following Open Source external libraries are incoporated. …

A time for Europe - Open source

As mentioned in this CNET article, Tuesday at OSBC London I opened the conference with a suggestion: Europe, the birthplace and cradle of the open source revolution, needs to reassert itself as the center of the open source phenomenon. Linux, MySQL, JBoss (Well, Marc is French with influences of Spain in him... :-), Trolltech, etc. These early open source leaders all came out of Europe.

As open source has commercially matured, however, the United States has taken over. Silicon Valley has funded the next round of open source, and we're not necessarily the better for it. There is an ethos in the projects and startups that emerged from the social democracies of Europe that one doesn't necessarily find in the capitalism-spawned companies.

Let's be clear: I am an unabashed open source capitalist. I live in the US and think …

Marc Fleury @ JBoss (The JiHat continues)

Marc Fleury is giving the opening remarks at today's OSBC London, and is talking about the rise of open source. As Marc said, it's no longer a question of "Why?", but rather of "How?" with regard to open source. Open source is not going away - it's only going to thrive and dominate.

A few interesting points:

  1. Debt to IBM. He talked a bit about the debt we owe to IBM for getting open source started with its $1 billion commitment to Linux, but noted that IBM seems conflicted now on that initial support for open source. It has a range of software businesses that compete with open source, rather than leverage it, in his words. True enough. In a company the size of IBM, you never get a single, consistent vision.

  2. Bottom-up and top-down phenomenon: the system administrators are driving adoption from the "bottom," whereas CIOs are pushing for adoption …

Different teams, same game

Watching the World Cup this year (and yes, I've watched many of the matches - last night's Switzerland vs. Ukraine match took years from my life - it was the essence of boredom), I've been reminded at how differently teams can play the same game. England with its obnoxious long balls into Peter Crouch. France with...well, so far, with nothing. Argentina with its flair and momentum.

Italy, however, takes "difference" to a new level. From today's The Times:

Italy’s method is rooted in pessimism. Ask an Italian whether the glass is half-full or half-empty and he is liable to reply that it is poisoned. Ask an Australian and he will ask if it is a free bar.The Italian I know best - Fabrizio - is no pessimist (He's taking on one of the most interesting and sexy markets on the planet), but the football/soccer he watches certainly is: …

MySQL: The database maverick on the rise

Jason Maynard of Credit Suisse First Boston, enfant terrible of the software analyst community (well, if you're a proprietary vendor, anyway), is at it again. He's got a great "Mavericks vs. Microsoft" series going, with a June 23, 2006 report coming from a call with Marten Mickos, CEO of MySQL. He makes some interesting points, including:

  1. Currently a private company, MySQL is...the world's most popular open source database with more than 8 million active installations.

  2. The primary revenue stream for the company comes from the conversion of free downloads of its database product into support contracts. So far, the conversion rate to paying customers runs about 1 for every 1,000 downloads. MySQL’s database has been downloaded close to 100M …

MySQL Ideas

Seems I have over time, thought of many ideas, jotted some notes on some, and even done some work, but everybody knows that “home projects” can take a long time.

Here are a few that have resurfaced over the past month, and I doubt I’ll ever get to them, or perhaps some other enterprising person has already done a similar thing. Of course most are for my own personal/professional gratification, but input from others of “great idea, when do we see it” could sway my interests.

INFORMATION_SCHEMA for MySQL Version 4

Why?

Well, quering the INFORMATION_SCHEMA is very cool, and long overdue for information gathering including statistics, schema definitions, schema version comparision tools etc. Of course there are concerns regarding the performance of using the INFORMATION_SCHEMA, and any design should significantly …

Open source and the living dead

I'm reading through an excellent JMP Securities research note called "Turning the Software Model Upside Down: The Proliferation of Open Source." [Subscription required.] It's a good overview of the open source business phenomenon - the how's and why's open source is increasingly dominating software - but I particularly like its analysis of proprietary vendor's likely responses to open source:

  • Proliferation of enterprise license agreements ("ELAs"?). Large enterprise software vendors such as Oracle Corporation, Microsoft and IBM may aggressively pursue ELAs with customers. Our due diligence suggests Oracle has employed this practice over the past few years. ELAs reduce the cost advantages of open source software since they are often structured as "?all you can eat" type of deal. Effectively the …

How I work

My work life is really fragmented at present, so I’ve decided a split approach in answer to Dave Rosenberg’s How I Work–what I have learned so far .

What is your role?
What is your computer setup?
What desktop software applications do you use daily?

CentOS 4.3
FireFox 1.5, ThunderBird 1.5, Gaim, SSH, Skype, Open Office 2.
Maybe not all of these every day, but some combination of each day –> MySQL 4.1, MySQL 5.0, MySQL 5.1, MySQL Workbench, Eclipse 3.1, J2DK 1.4.2, J2DK 5.0, Apache Tomcat 5.0.28, Apache Httpd 2.0.53, JMeter.

Presently also configuring a new laptop drive running …

A better VNC

I’ve been using VNCViewer from RealVNC under Linux to remote connect to an older machine running windows. Two reasons, I don’t need yet another screen on my desk, and I need windows to adequately test and use the MySQL GUI products, in particular MySQL Workbench.

I never realised there was a better way, particularly over a local network, a command called rdesktop which is capable of natively speaking Remote Desktop Protocol (RDP).

$ su -
$ yum install rdesktop

This did only give me version 1.3.1. The current version 1.4.1 available from the rdesktop Website does provide greater commands including the syntax I use.

su -
cd /src
wget http://optusnet.dl.sourceforge.net/sourceforge/rdesktop/rdesktop-1.4.1.tar.gz
tar xvfz rdesktop-1.4.1.tar.gz
cd rdesktop-1.4.1
./configure
make
make install …
