It has been more than a year since my self-imposed hiatus from serious MySQL development started and I think it is about time that I get back into the saddle. I have a handful of working prototypes but I should get the code out there, back into the community.I learned a bunch of stuff during the past year at Google but in the end, working on JavaScript, HTML/CSS and Google proprietary languages

Just spotted the following posting from Paul DuBois on the internals mailing list:

I'm engaged in a project (WL#3403) to compile information that will provide better information about our errors and error messages:

• What an error means
• Likely causes of the error
• How to rectify or work around the error

The general idea is to provide our users something more than a list of error codes and the messages from errmsg.txt, such as the manual currently includes here:

I just applied the external stored procedure patch to a branch of MariaDB and uploaded it to LaunchPad.You can see the branch at https://code.launchpad.net/~atcurtis/maria/5.1-wl820Note that this is not in any reasonable condition to merge into MariaDB. Hopefully we can engage in dialog as to how we can bring this feature properly to MariaDB, MySQL and Drizzle, hopefully making the plugins

Well, it took us a little while (we’ve been busy !), but we’ve now posted our presentations on InnoDB from the MySQL Conference and Expo 2009. You can download these presentations by Heikki Tuuri, Ken Jacobs and Calvin Sun from the InnoDB website, as follows:

• Ken and Heikki: InnoDB: Innovative Technologies for Performance and Data Protection
• Heikki: Crash Recovery and Media Recovery in InnoDB

Files used in conference presentation here: UC2009 presentationI think todays presentation for Perl Stored Procedures for MySQL was quite successful. The audience was quite engaged and asked questions throughout (yes, I invited questions through the talk). I made sure to mention Eric Herman's Java plugin because even though he didn't get time to submit a talk, the work is noteworthy. Sometimes I

Finished my presentation earlier this afternoon. I had a better audience than last year and there was interest in the download URL for the source tarballs so I hope to see people hacking on it soon.The link to the presentation is here.There has been lots of good communication with staff from MySQL^WSun Microsystems^W^WOracle so maybe we shall see this code to begin to be integrated soon. In other

Just noticed that the Drizzle list has had more messages since June last year (2008) than the mysql internals@ list has had since March 2006.

Less than 48 hours after starting to scratch this itch, I have table functions working in my WL820 repository on Launchpad.It is pretty nifty:mysql> INSTALL PLUGIN Deep_Thought SONAME 'psm_example.so';Query OK, 0 rows affected (0.10 sec)mysql> CREATE FUNCTION test.FooAnswer() -> RETURNS TABLE(answer TEXT) -> NO SQL LANGUAGE Deep_Thought EXTERNAL NAME 'compute';Query OK, 0 rows affected (

I have merged the code from the mysql-5.1 launchpad repository which should put this repository up to the recent 5.1.28-rc version. You can examine the source repository here.On a related note, had a brief email exchange with Eric Herman and so I hope that there will be time for him to do some work to complete the support for Java stored routines.

Ever since I submitted the "External Language Stored Procedures" project which Eric and myself have been working on to be listed on FreshMeat, it has gained a small number of interested users and we have just started to get some feedback. Yay! Always nice to know when people are using your code. Okay, so one of the emails contained a feature request: Support for PHP stored procedures. I think I
