I was so damn proud of myself to stumble upon a cool critical bug in MySQL, only to find it was a duplicate of another bug discovered 3 days earlier by someone else, and not just someone, but Paul DuBois, the author of no less than 3 books about MySQL and the likes.
My test case was simpler though - judge for yourself (#32376 vs #32260).

It goes like this - Find a MySQL 5.1.22 (or less). Connect. Run the next lines of code. Server is down. Simple, eh?

create table test.t(c int) engine = innodb;

select @var := c as c
from t
order by c asc;

This is documented as a casual "Some uses of user variables in a query could result in a server crash." in the …

Long before I first got to know about Sun’s acquisition of MySQL, I had booked this year’s prime skiing holiday. That’s going to be the week right after the Integration Kickoff in Menlo Park, on 3-9 February 2008. And it’s a special type of skiing holiday: It’s Boys Only, i.e. I’m going with my 13 year old son Alexander to Pitztal in Austria.

We’re going to the Ötztaler Gletscher, the glacier where Ötzi the Iceman, a well-preserved natural mummy of a man from about 3300 BC (53 centuries ago) was found in 1991.

Determined not to end up like Ötzi, Alexander and I will get extensive off-piste training under the direction of a certified Austrian mountain guide who according to his web profile has climbed “Cho Oyu, …

Monday, I’m off to the Sun-MySQL Integration Offsite in Menlo Park. That’s where we’re going to plan the next steps of making MySQL a part of Sun. It’s a three-day offsite, from Tuesday to Thursday, and I’m looking forward to meeting with many new colleagues.

Integrating companies is never easy, and I don’t expect this integration to be trivial, either. But thinking about the many cultural similarities between MySQL and Sun, about our mutual commitment to Open Source, about the positive reception of the acquisition by MySQL employees, and about the positive reception also from the side of Sun, I think we’re in for a great ride and some exciting times, in the best sense of the words.

Sun, here we come!

I spent a couple of hours on Friday at Sun’s office in Finland. It was a visit full of mutual anticipation.

Until the deal is closed, Sun and MySQL are merely planning joint activities, with execution happening once the deal is closed. Already now, lots of touching points were revealed in the informal discussions with Margot Wik, Thomas Branders and their colleagues. It seems both Sun and MySQL have a hard time not going into detail, but such are the rules of the game.

Before Sun Finland’s Friday afternoon coffee, Margot, Thomas and I picked the opportunity to drop by at Teknologföreningen, the Swedish language student corporation at Helsinki University of Technology. That’s the place where I learned to know Margot and Thomas, as well as our CEO Mårten, and many others. And where I “learned” …

Hi!

We have now made the bitkeeper tree of Maria public at http://mysql.bkbits.com


Maria is a new storage engine that Guilhem, Sanja, Sergei and I have been working on for the last 2 years.

(Before anyone comments that this is not 'that much' for 2 years work, I would lke to note that the first 1 1/2 this was done part time while we have finished other projects; It's only during the last 4 months we have been working full time on this. From now on we Maria is our main focus.)

We are still discussing in MySQL AB how and when we will start to make binary distributions of Maria; Until then, please use the bk tree to test the Maria engine! We are now in a state of Maria 1.0 with 'no known bugs' (which of course doesn't mean that there isn't any bugs just that we belive we are in 'reasonable good shape') and we need the help from …

Hi!

Recent events have convinced me that it's finally time for me to start blogging.

The first thing I would like to talk about is about Sun buying MySQL AB. In a second blog entry I will then talk about the Maria storage engine, a project that I have been working on for the past two year (first half time and now full time).

Personally I think that the deal with Sun is the best thing that could have happened to us. When David, Allan and I originally took on investors on MySQL we did know that there was only two ways out; Either we would make an IPO or we would be bought by some large company.

I was always a bit afraid of the IPO route, as in this case there was no guarantees long term that MySQL AB would be a company that would focus on open source. I am quite confident that With Sun, who has made strong commitments to open source with things like Open Solaris, Open Office and making Java …

PHP is a nice programming language for web applications with a large number of databases supported.

PDO is one of many database access abstractions trying to unify the way PHP talks to databases. Unlike most of these, PDO is written in C and not in PHP.

Wez Furlong wants to improve PDO "Version 2". In particular he and others want to produce an open spec that can be used by anybody including database vendors to code against, add unit testing for the spec and the drivers that claim to support it and improve metadata handling for PDO.
