[Maria-discuss] Someone from MariaDB to talk at ODTUG conference?
by Henrik Ingo 11 May '10

11 May '10

Hi all I just had a talk with Sheeri about an upcoming Oracle Developer Tools User Group conference in June in Washington. There will be a 1 day MySQL track on Sunday, plus possibly some other MySQL talks: http://www.odtugkaleidoscope.com/agenda.html Sheeri was asking if someone from Monty Program (or, imho any MariaDB activist) wanted to present. Things to note: - The conference is application developer oriented, so things like optimizer internals or tuning InnoDB buffer size is not interesting. - We don't want to talk about MariaDB per se. We don't want to introduce this crowd to the reality of there being so many MySQL forks. The previous points pretty much rule out everything we presented at the MySQL conference :-) Good topics could be: - Efficient and inefficient SQL queries in MySQL - UDF tutorial and examples The first suggestion is imho good. These Oracle experts need to learn to avoid certain things like most subqueries, and how to work around that. But on the other hand this is a natural topic for someone from us to present, since we could then also mention that correlated subqueries will work creat in MariaDB 5.3, which may even be beta by this point? The second suggestion is an example of something that would be considered very technical topic in this conference. Now the question is who to send there? This is not significant enough that someone from Europe would fly in - heh, most of us would probably not volunteer themselves at this point :-) In US I see Bryan or Daniel as candidates for this, Igor possibly for the UDF kind of talk more than the app developer talk. And, it needn't be a Monty Program employee, let me know if you're interested. Colin, will you pick this up from here? henrik -- email: henrik.ingo(a)avoinelama.fi tel: +358-40-5697354 www: www.avoinelama.fi/~hingo book: www.openlife.cc

[Maria-discuss] MariaDB shutdowns silently
by Joshua Partogi 23 Apr '10

23 Apr '10

Dear all, I am currently running MariaDB in production and I often found it would shutdown itself silently after inactivity. The application itself is using Ruby on Rails. I have disabled the max_timeout settings in my.cnf but the problem still occurs. Is there anything else I should watch out for to prevent this issue continuing to occur? Thank you very much for your assistance. Kind regards, Joshua -- http://twitter.com/scrum8

[Maria-discuss] What is the future of MariaDB
by Joshua Partogi 20 Apr '10

20 Apr '10

All, Many people were feeling uncertain whether to use MySQL when Sun was bought by Oracle. I was one of those people and that is why I chose MariaDB for my product now. But I need to know what is the plan for MariaDB in the future? Would there be any chance that MariaDB will be sold to another company just like MySQL got sold to Sun? Or would MariaDB always be a community owned? Kind regards, Joshua -- http://twitter.com/projexion

[Maria-discuss] Generic Linux Build requirements
by Brian Evans 06 Apr '10

06 Apr '10

http://askmonty.org/wiki/index.php/Building_MariaDB:Generic_Linux says: * gcc 2.95.2 or later However, according to [1] , Gentoo claims that GCC 4.3 is required due the use of c++ templates in the server. [2] also states that GCC-4 is absolutely required with a failing build log. [1] http://bugs.gentoo.org/show_bug.cgi?id=307251#c5 [2] http://bugs.gentoo.org/show_bug.cgi?id=284946

Both tables are innodb, the permissions are fine. Thanks, Alex

[Maria-discuss] Reliable tarball source
by Brian Evans 02 Apr '10

02 Apr '10

I just noticed that MariaDB 5.1.44 was posted on askmonty.org but not lauchpad. What will be the most reliable URL to pull the latest source tarball when it is released? I'd prefer to make it automated as Gentoo can simply relate a build script name to a version.
