I had an interesting IRC discussion the other day with Monty Taylor about what turned out to be a limitation in Valgrind with respect to debugging memory leaks in dynamically loaded plugins. Monty Taylor’s original problem was with Drizzle, but as it turns out, it is common to all of the MySQL-derived code bases. When… Continue reading Debugging memory leaks in plugins with Valgrind

Conference time!
It is conference time for me. I just came home from FOSDEM 2010 where we had a booth and I gave a talk. At the end of the month there will be a company meeting in Iceland for Monty Program, followed by Open Source Days 2010 where I will also be speaking. And then in… Continue reading Conference time!
RunVM, a tool for automated scripting inside virtual machines
In the Autumn, I wrote about some experiments I did using KVM and virtual machines to build and test MariaDB binary packages on a number of different platforms. In the period since then I added some polish and refinements, and the system is now running well for some time. We build and test packages for… Continue reading RunVM, a tool for automated scripting inside virtual machines
Oracle speculations
The Planet MySQL has been abuzz with opinions for or against the acquisition of Sun (and in particular MySQL) by Oracle, but I do not have a strong opinion to chime in with in support of either groups. The reason is that I do not know anything about antitrust laws, which is the legal basis… Continue reading Oracle speculations
MariaDB Buildbot configuration file published
I have now published the Buildbot configuration file that we use for our continuous integration tests in our Buildbot setup. Every push into main and development branches of MariaDB is built and tested on a range of platforms to catch and fix any problems early (and we also test MySQL releases before merging to easily… Continue reading MariaDB Buildbot configuration file published
Building MariaDB/MySQL with Buildbot and KVM
Testing and automation. These two are key to ensuring high quality of software releases. Ever since I worked briefly in the team at MySQL AB that is responsible for creating the binary (and source) packages of MySQL releases, I have had the vision of a fully automated release procedure. Whenever someone pushes a new commit… Continue reading Building MariaDB/MySQL with Buildbot and KVM
Valgrinding Drizzle
Like so many others, I got interested in the Drizzle project when it started. Some good ideas, lots of enthusiasm, and just pure GPL license, no “yes, we will take your work for free and sell proprietary licenses to it” SCA. I even started contributing some development, fixing a number of Valgrind-detected bugs in Drizzle.… Continue reading Valgrinding Drizzle
Placeholders and SQL injection, part 2
Actually, what I really wanted to blog about before getting carried away with irony yesterday was an old idea on how to force my developers to use placeholders exclusively for SQL queries in applications. As should be apparent from yesterdays blog entry, I am strongly in favour of using placeholders for interpolating values into SQL… Continue reading Placeholders and SQL injection, part 2
Det skal for øvrigt være med kælder!
En entreprenør får bestilling på et hus. Arkitekttegningerne kommer på plads, byggeriet går igang, der er rejsegilde, og man bliver klar til aflevering. Bygherren får nøglerne og flytter straks ind, flyttebilen er der allerede. Og da flyttelæsset er på plads, kommer det fra bygherren: “Hov forresten, jeg kommer i tanke om noget: Kan I ikke… Continue reading Det skal for øvrigt være med kælder!
