[Maria-discuss] Replication to galera cluster
by Igor Mazur 18 Nov '15

18 Nov '15

Hi, I've tried to setup replication from production MariaDB (lets name proddb) to a data warehouse on Galera cluster (dw1, dw2 and dwarbitrator - last is a node with garb). Made master-slave link between proddb and dw1. And on dw1 I have actual data, but they are not updated on dw2. Other schemas successfully transfer their updates between dw1 and dw2 as required. Looks like only difference that other schemas are updated with direct requests to dw1 and dw2, and replicated schema is updated only through replication. Does anyone have experience with a similar configuration? Igor

[Maria-discuss] New Question: Buffer size issue?
by AskMonty KB 18 Nov '15

18 Nov '15

Hello, A new question has been asked in "General FAQ" by Bytesmiths. Please answer it at http://mariadb.com/kb/en/buffer-size-issue/ as the person asking the question may not be subscribed to the mailing list. -------------------------------- I have a query that returns a string considerably longer than 1024 characters. It was working properly in MariaDB 5.1. I have upgraded to 10.1.8, and it appears that the query return is being truncated at 1024 characters. I see this behaviour in three separate tools, including php mysql calls, phpMyAdmin, and the mysql command line tool. (It was the mysql CLI, piped to wc, that told me that exactly 1024 characters were being sent, but no more.) Assuming this is not a bug, but rather some variable to be tweaked, can someone point me in the right direction? Thanks in advance! BTW: Here is the query, which has not changed since it was written in 5.1: <pre>SELECT GROUP_CONCAT(DISTINCT '<a href="/wiki/', p.family, '" title="', f.explanation, '">', p.family, '</a>' ORDER BY p.family SEPARATOR ', ') FROM s_plants p LEFT JOIN s_plant_families f ON p.family = f.family</pre> This query basically returns a string containing a long list of plant family names, wrapped in HTML links. This is what I get back: <pre><a href="/wiki/Agavaceae" title="Agave family">Agavaceae</a>, <a href="/wiki/Aizoaceae" title="Fig-Marigold or Ice Plant family">Aizoaceae</a>, <a href="/wiki/Alliaceae" title="Onion and Garlic family">Alliaceae</a>, <a href="/wiki/Amaranthaceae" title="Amaranth family">Amaranthaceae</a>, <a href="/wiki/Anacardiaceae" title="Cashew or Sumac family">Anacardiaceae</a>, <a href="/wiki/Apiaceae" title="Celery or Carrot family, formerly Umbelliferae">Apiaceae</a>, <a href="/wiki/Apocynaceae" title="Periwinkle family">Apocynaceae</a>, <a href="/wiki/Araliaceae" title="Ginseng family">Araliaceae</a>, <a href="/wiki/Asteraceae" title="Daisy family, formerly Compositae">Asteraceae</a>, <a href="/wiki/Boraginaceae" title="Forget-me-Not family">Boraginaceae</a>, <a href="/wiki/Brassicaceae" title="Cabbage family, formerly Cruciferae">Brassicaceae</a>, <a href="/wiki/Campanulaceae" title="Bellflower Family">Campanulaceae</a>, <a href="/wiki/Caprifoliaceae" title="Honeysuckle family" >Caprifoliaceae</a>, <a href="/wiki/Car</pre> That last link with the open quote in the open anchor tag sure plays havoc with the rest of the page... :-) -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/buffer-size-issue/

[Maria-discuss] mysql_install_db as user
by Felipe Gasper 13 Nov '15

13 Nov '15

Hello, Is this script supposed to be runnable as a normal (i.e., non-root) user? In MySQL 5.6 there is logic that prevents the chown() of the mysql data dir when running as non-root. MariaDB 10.1.8 doesn’t seem to have this logic, so the script fails when chown() fails. Is this change intended? We have tests that verify functionality of user-created, UNIX-socket-only MySQL/MariaDB servers. These work on MySQL 5.6 but not on MariaDB 10.1. Here is the command-line output: --------------- ~/temp $ /usr/bin/mysql_install_db --datadir=mysqldata chown: changing ownership of `mysqldata': Operation not permitted Cannot change ownership of the database directories to the 'mysql' user. Check that you have the necessary permissions and try again. bash: __git_ps1: command not found --------------- Thank you for your time! -Felipe Gasper Houston, TX

[Maria-discuss] Donating during the downloads
by Colin Charles 12 Nov '15

12 Nov '15

Hi, Today I downloaded Ubuntu and saw this awesome page for donations. Do you think we should do this for the MariaDB Server / Connectors / etc. so that the MariaDB Foundation gets funded as well? I know that even LibreOffice has done this (http://donate.libreoffice.org/) We should consider this. Otto, what do you think? -- Colin Charles, Chief Evangelist, MariaDB Corporation blog: http://bytebot.net/blog/ | t: +1-347-903-3201 | Skype: colincharles | Twitter: @bytebot
