How MySQL Sandbox Solves All My Problems

I just can’t help thinking about how amazing and useful MySQL Sanbox is. There are so many things that it can do, and so many problems that it solves for Database Developers. When it comes down to it, I really think that every project that uses MySQL can benefit in some way or another just by using […]
MySQL Community Contribution: One bug fix at a time ...
Employee +0 Vote Up -0Vote Down

It is all about one bug fix, one little feature, one step at a time.

Armin Schöffmann fixed a bug (Deadlock in mysql_real_query with shared memory connections, is what Armin calls it), Armin signed the Sun Contributor Agreement (24 March 2009), Vladislav Vaintroub and Davi Arnaut reviewed, committed and queued the patch to MySQL 5.0 bug team (26 and 27th of March, 2009).

That's a great example of open, contribution-based MySQL development with real results.

Thank you Armin!

Thank you Vlad!

Thank you Chad!

Thank you Davi!

Thank you ... the one whose name I've left out! (Feel free to leave a comment below.)

MySQL Ideas for Google Summer of Code (GSoC)
Employee +0 Vote Up -0Vote Down


Check out the ideas from MySQL for Google Summer of Code 2009!

These are specially-selected projects for students who are looking to do some coding in a real, open-source, highly-adopted software environment. 

The learning experience will be tremendous given that MySQL engineers will be mentoring them. 

Some student stipend is provided by the Google Summer of Code. It is intended for students to gain "exposure to real-world software development scenarios and the opportunity for employment in areas related to their academic pursuits."

Google Summer of Code: Help improve MySQL documentation!
Employee +0 Vote Up -0Vote Down

MySQL is participating in Google Summer of Code 2009 (GSoC for short), and so is the MySQL documentation team. We've just put our ideas on this page; you might want to have a look if you're interested in applying for a GSoc project.

One of the projects is purely technical and doesn't involve writing any documentation, but rather improving the technique that goes on behind the scenery.

The other project does involve writing documentation, but it's mostly (if not exclusively) about creating examples for the Connectors & APIs chapter of

Choosing the Tools for Release Management
+0 Vote Up -0Vote Down
When planning which tools you use to maintain, build, and deploy your database, it is important to look at what tools are already available and in use within your organization. Using existing tools can save you a lot of time and helps standardize processes across your organization. If you manage both application development and database development - integrate your tools and processes from the onset to make your release cycles as smooth as possible.
New Sun Contributor Signatories for MySQL
Employee +0 Vote Up -0Vote Down

I just checked the "Sun Contributor Agreement" (SCA) signatories list, and there are already 11 people who have signed the contributor agreement with an intent to contribute to MySQL.

Among the signatories, you will also notice Paul McCullagh of PrimeBase/PBXT fame. (To learn about how to submit your SCA paperwork, see here.)

Signing the SCA with an intent to contribute to any given Sun-sponsored open-source project would also suffice when it comes to contributing to any other Sun-sponsored open-source project.

The Juice is Loose - MySQL Benchmark
+0 Vote Up -0Vote Down

Well I am still not happy with a lot of the code, but I have had some people ask me to help test my attempt at a new MySQL benchmark. So I cleaned up the code a bit and pushed what I had to LaunchPad. It’s way to early for this to be ready for prime time, I am using it to stress flash, but as I do i am still finding issues, so use at your own risk. My goal is to make this more generic and allow user customizable SQL files to be loaded in…. something like:

1 | select * from table where a =?  |  rand | a | 1000
2 | select * from table1,table2 where table1.id=table2.id and c = ? and d=? | rand,1-200 | c,d | 10

This would mean execute query #1 , using a random value from a 1000 times in a loop before exiting… and then execute query 2, 10 times using a rand value from c, and a value between 1-200 for d….

But that is a ways off.

For now I support 4 tests which

TomTom Linux impact light hit so far
+0 Vote Up -0Vote Down

I’ve been talking to device manufacturers and the Linux-centered software providers that feed them code for mobile phones, TV set-top boxes, industrial control, automotive technology, medical devices, military uses and a slew of other categories commonly classified as embedded devices, and I can definitively report that I am not hearing or sensing any fear, uncertainty or doubt (FUD) as a result of Microsoft’s TomTom patent suit.

I wrote last month that the controversial MS TomTom suit was not aimed at Linux as much as TomTom and some market categories for Microsoft. While we must all remind ourselves that anything may be possible considering court rulings and Microsoft strategies, I don’t see Microsoft’s TomTom suit as truly aimed at Linux. If

Using the google graph API with MySQL stored functions

After reading Alex’s blog post on generating graphs using google’s graph API I decided to do something similar for MySQL.

Improving the Storage Engine “API”
+0 Vote Up -0Vote Down

I increasingly enclose the API part of “Storage Engine API” in quotes as it does score a rather large number on the API Design Rusty levels (Coined by Rusty Russell). I give it a 15 (out of 18. lower is better) in this case “The obvious use is wrong”.

The ideas is that your handler gets called to write a row (the amazingly named handler::write_row()). It’s passed a buffer which is the row to be stored. An engine that uses the MySQL row format (lets say, ARCHIVE) will simply pack the row and write it out.

Unless there is a TIMESTAMP field with auto set on insert. Up until now (and still now in MySQL) the engine had to check if this was the case and make sure the timestamp field was updated.

Golden Rules for Contribution-based Communities
Employee +0 Vote Up -0Vote Down

There are some basic, golden rules when it comes to having a vibrant community of contributors.

The following are rules I have extracted and learned based on my experience managing and working with engineers actively involved and participating in the Apache/Derby, PostgreSQL and MySQL open-source communities. These rules are also based on extensive discussions with many folks involved with the MySQL community, with the PostgreSQL community and with the Apache/Derby (Java DB) community, over many years.

Before I go through these rules, I would like to thank Marten Mickos for having suggested some of the headings for these rules. (I originally had much longer headings for all of them.) I would also like to thank many of MySQL, PostgreSQL and Java DB colleagues, as well as to many other colleagues involved in open-source development, for having

“Ban FRM Now!” branch in Launchpad

Now we’re reading part of the table information out of the proto file on disk instead of the frm.

Not everything (yet) but a bit. Good first steps. Had to fix bugs along the way as well (and find weirdness in FRM file format…).

Progress is being made.
