[Maria-discuss] Default Database Engine
by Richard Dunn 30 Nov '09

30 Nov '09

I have compiled and installed mariadb-5.1.39 on Mac OS X 10.6.2 and installed a 64-bit binary on CentOS 5. In both cases, MyISAM is still the default database engine. I would have expected it to be Maria. Did I miss something? Thanks, Richard

[Maria-discuss] Additional promise to the MCA
by Henrik Ingo 09 Oct '09

09 Oct '09

Hi all As Monty blogged some time ago http://monty-says.blogspot.com/2009/08/thoughts-about-dual-licensing-open.h… ...we want to add a promise to our MariaDB contributors signing the MCA, that we will not use their contributions to restrict other licensees ability to contribute to Open Source. This text has now been approved by a lawyer. The question is, is it understandable? ********************************** Additional promise to contributions under the Monty Program Contributor Agreement Monty Program Ab promises to each contributor assigning rights under the Monty Program Ab Contributor Agreement, that when licensing 'products' (software), that include a contribution, to other 3rd parties, the license will be either i) an Open Source license (www.opensource.org) or ii) another license, in which case: * the other license will NOT restrict the licensee from making his own modifications to the product, including adding other suitably licensed code or other 'materials' from other sources (such as code available under suitable Open Source licenses) * the license will NOT restrict the licensee from publishing his own code or other 'materials' including, but not limited to, under an Open Source license. As a special note, it is observed that the Monty Program Ab Contributor Agreement itself fulfills these requirements. Also note that this promise does not not extend as a requirement to 3rd parties so as to restrict their rights to license products containing contributions. ********************************** We are especially interested to get feedback on the understandability of the last paragraph. henrik -- email: henrik.ingo(a)avoinelama.fi tel: +358-40-5697354 www: www.avoinelama.fi/~hingo book: www.openlife.cc

For example, does the entry about MariaDB NOT supporting NDB need it's own Manual page or not? Any contributions to the above stubs are *very* welcome. Any contributions to any of the other refman pages are likewise welcome: http://askmonty.org/wiki/index.php/Manual:Contents Henrik> Could the list itself be a basis for a changelog document and Henrik> then we make release notes into a more human readable document?

[Maria-discuss] License for MariaDB 5.1 Reference Manual
by Daniel Bartholomew 24 Sep '09

24 Sep '09

All, What license should we use for the MariaDB 5.1 Reference Manual? Some of the suggestions I've seen on IRC include: FDL : http://www.gnu.org/copyleft/fdl.html CreativeCommons : http://creativecommons.org My personal preference is to use the Creative Commons BY-SA license: http://creativecommons.org/licenses/by-sa/3.0/ This is the license used by Wikipedia and the share-alike part of the license ensures that the content remains open. It's a common license and is well understood and liked by a lot of people. Henrik mentioned the problem of attribution with CC licenses, but I don't think this is an issue with the mediawiki software we're using because of the edit histories and edit summaries, both of which fulfill this requirement. For example, the history page for the PBXT entry in the manual attributes me and Paul McCullagh for our contributions to the article: http://askmonty.org/wiki/index.php?title=Manual:PBXT_storage_engine&action=… I don't have much experience with the FDL, so if someone has reasons why we should use it, please share. Thanks. -- Daniel Bartholomew

[Maria-discuss] MariaDB 5.1 Reference Manual Introduction
by Daniel Bartholomew 22 Sep '09

22 Sep '09

All, The MariaDB 5.1 Reference Manual is progressing, but it needs an introduction. If you haven't taken a look at it yet, here is the TOC for the manual: http://askmonty.org/wiki/index.php/Manual:Contents At this stage we do not have a full or complete manual. Eventually we will have one, but creating it will take time. The purpose of the MariaDB 5.1 Reference Manual is to just document the differences between MariaDB 5.1 and MySQL 5.1 with the understanding that users can refer to the MySQL 5.1 manual for anything not covered in the MariaDB 5.1 manual. I'm currently working on an outline for the introduction page. One thing I think the intro should have is a version of the above paragraph to set expectations (we don't want users to think that we think our manual is complete). Beyond that, what other things should the introduction include? Also, if anyone knows of anything else which should be added to the manual, please let me know (or jump in and add it). Thanks. -- Daniel Bartholomew

As far as I know, with the advent of the BSD licensed libdrizzle (https://launchpad.net/libdrizzle ), which also runs with MySQL (and I assume MariaDB), the dual licensing model is now irrelevant. My reading of the GPL license (http://www.gnu.org/copyleft/gpl.html) is that only programs that link GPL components become part of the greater work. From the GPL section "1. Source Code.": "For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those subprograms and other parts of the work." So linked sub-programs are included. But: "However, it does not include the work's System Libraries, or general- purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work." So an unmodified free program like mysqld (the MySQL daemon), are not part of the work. This means that a programming linking libdrizzle, and then accessing mysqld over a communications _channel_ (like TCP, socket, pipe, etc), does not need to be GPL. > By agreeing to this arrangement, contributors ensure that Sun is > able to continue that. > Do you want that? > > "yes" might be a valid choice, on the basis that it might be more > important to get the changes upstream. > But I think the question needs to be asked explicitly.

Of course, all of the MariaDB source code is available as GPL, just like for MySQL.

Actually, it is very important that MariaDB copyrights are pooled to one owner, we could get into trouble if we didn't do that. (I won't give the details, so as not to give any ideas.) Same is true for XtraDB, where we have advised Percona to pool the copryights from any non-Percona contributors. It's not like we (MP) want to own everything, but somebody has to do it. Personally my first motivation in favor of pooling copyrights was however entirely benevolent towards MySQL and its users. By having the copyrights pooled in one place (rather than just going all GPL), we are able to assign the code back to Sun (if we so agree), and I'd really like to do that so that all MySQL users, also the commercial licensees would benefit from the MariaDB work. henrik -- email: henrik.ingo(a)avoinelama.fi tel: +358-40-5697354 www: www.avoinelama.fi/~hingo book: www.openlife.cc
