[Maria-discuss] Files under /etc/my.cnf.d/ read by default
by Honza Horak 05 Feb '13

05 Feb '13

Hi guys, while we were packaging MariaDB into Fedora (finally) we used the upstream's cnf files structure, which means /etc/my.cnf, that includes all files from directory /etc/my.cnf.d/* using statement !includedir. That works fine when user installs (not updates) the MariaDB packages without having them installed before. The problem is if user has changed /etc/my.cnf before updating -- then /etc/my.cnf doesn't get updated (!includedir won't be added) and we end with files under /etc/my.cnf.d/* but nothing what includes them. That is quite confusing for users that may change something in /etc/my.cnf.d/client.cnf but nothing happens. Since files under /etc/my.cnf.d/* are empty by default it shouldn't do any harm if all files corresponding with /etc/my.cnf.d/*.cnf template get loaded even without !includedir in /etc/my.cnf. Actually I believe that is what users expect to happen when they see files under /etc/my.cnf.d.. So, that's basically what I'm proposing -- read files under /etc/my.cnf.d/* by default, without a need to use !includedir. What do you think? Regards, Honza

Re: [Maria-discuss] Reading a field's default value from a trigger
by Bruce Kirkpatrick 04 Feb '13

04 Feb '13

For anyone encountering the "Field 'xxx' doesn't have a default value" when running insert/update/replace statement on MariaDB, I found that this is actually caused by the sql mode STRICT_TRANS_TABLES. This also fixes when a trigger updates the default value of the field. I believe the default options for MariaDB windows installer cause this option to be enabled, whereas I had previous never designed my application for the various modes supported. You can also fix the issue by giving every field in the table an explicit default value of 0 or '' except for text/longtext columns. I choose not to do that since I don't know how many other things change with STRICT_TRANS_TABLES. If you change my.ini / my.cnf to sql-mode="", you won't have this error occur anymore. You can run SELECT @@GLOBAL.sql_mode; on your mysql server and mariadb server to compare what the current settings are. This is my first post to the MariaDB mailing list. Sorry if I did it wrong. I've been using MySQL for over 10 years and decided to migrate to MariaDB now. -- Bruce Kirkpatrick<http://www.skyflare.com/> 386-405-4643

[Maria-discuss] MariaDB's tracking of MySQL changes
by Christian Convey 04 Feb '13

04 Feb '13

Can someone explain the relationship between MySQL and MariaDB code updates? I've read that MariaDB is a drop-in *replacement* for MySQL. But I've also read that MariaDB treats MySQL as an upstream code base. So what's the deal? Does MariaDB have alternative implementations for just some of MySQL's components, and when a new MySQL release comes out, MariaDB updates just those components for which it doesn't have its own versions? [This is a re-post from the #maria IRC channel, where I got no answer.] Thanks, Christian

The MariaDB project tries to support as many different operating systems and Linux distributions as possible. However, when a distribution or OS stops receiving upstream security and other updates it becomes difficult to provide packages for that platform. In such cases, our policy is to deprecate that platform and stop building binary packages for it in our build system. As of 1 Feb 2013, we will stop building and testing packages for the following: - Fedora 16 "Verne" - Debian 5 "Lenny" - Ubuntu 10.10 "Maverick" - Ubuntu 11.04 "Natty" Even after your chosen Linux distribution is deprecated, packages and support are still available. Companies such as SkySQL and Monty Program (among others) provide paid support for all versions of MariaDB and back to even very old MySQL versions. This includes packaged binaries. More information on our deprecation policy can be found at: https://kb.askmonty.org/en/mariadb-deprecation-policy/ - - Archived Releases - - - - - - - - - - - - - - - - - - - - - - - - From the beginning of the MariaDB project in 2009 we've kept all of our old releases online via our network of mirrors. Doing this is great for those few who are interested in old releases, but the disk space required to host all of our old releases is over 130 Gigabytes at present and grows by several gigabytes with each new release. This is too much for some of our mirrors to handle. So, starting with this round of releases our primary mirror will only host the most recent few releases in each series (5.5, 10.0, 5.3, and so on). Mirrors are, of course, free to keep archiving every release, but the primary mirror that they pull from will not. Old releases do have value, so for those that are interested in old releases, we are setting up a simple, no frills, archive server which will host them. Once the server is up and running, links to archived releases on https://downloads.mariadb.org will point at the archive server. During the transition period, links to some old releases may disappear for a short time, but don't worry, they haven't been deleted, they're just being moved! If you have hundreds of spare gigabytes on a fast connection and would also like to host the complete MariaDB archive, contact us at mirror at mariadb.org and we'll include a link your mirror from our archive server.

[Maria-discuss] noinstall package for MariaDB
by Vineet Deodhar 25 Jan '13

25 Jan '13

Hi ! At present, I am using MySQL noinstall version (which doesn't require ANY installation). Just copy & paste the folder & start. Is there any way to use MariaDB without installing? (Maybe replace MySQL folder containing the binaries with MariaDB folder? If yes, from where to get the noinstall folder for MariaDB?) Thanks, Vineet

[Maria-discuss] Compatibility problems switching Glassfish application from MySQL to MariaDB
by Guido Winkelmann 24 Jan '13

24 Jan '13

Hi, I'm having some problems switching one of our Java/Glassfish-based web applications over from MySQL to to MariaDB. Since the MariaDB project advertises the software as a fully compatible drop- in replacement for MySQL, the first thing I did was simply stop the MySQL server, uninstall it, and then install and start MariaDB (5.5.28a, from Gentoo portage). We have got several C/C++ based application that access our MySQL databases. Those took a recompile, but afterwards continued to work as if nothing had happened. I didn't have as much luck with our glassfish-based web frontend though. The first problem was that the existing MySQL connector is apparently unable to connect to MariaDB, so I deleted the existing JDBC Connection Pools and replaced them with new ones using the MariaDB Java Client instead. This worked on the surface, however now I'm getting a lot of exceptions whenever I'm accessing parts of the application that make use of BINARY type columns. According to the developer (of the web application on question), this is because either MariaDB itself or the connector are returning binary columns as type string, causing the persistance layer to attempt to convert them to a string object. Since the binary columns in question contain various unprintable characters, including zero-bytes, this fails. Can someone please help me with these problems? Guido

[Maria-discuss] Trouble installing MariaDB 5.5 on Ubuntu 12.04 (& 12.10)
by Aaron Anderson 23 Jan '13

23 Jan '13

Gang, I've installed MariaDB on several Debian/Ubuntu systems in the past few months, without any issues. ~2 days ago on an Unbuntu 12.10 system did an apt-get update/upgrade/dist-upgrade. I believe that MariaDB was updated in that process. After the updates, mysql was "gone" My apps couldn't find it, it wasn't running, etc. I was in a hurry so I had to fall back to the standard mysql package so not a lot of into there. I built a new Ubuntu 12.04 LTS server, added the Maria repo, did an apt-get update/ugprade/dist-upgrade. Rebooted. Here's some output...
