[Maria-discuss] int(x) does nothing
by Richard Couture 15 May '13

15 May '13

We discovered that declaring an int(x) of x characters does not seem to impose any restrictions what-so-ever on the size of data that can be stored in that int. Storing an int of greater dimension than that which was declared does NOT even generate a warning. Can someone please tell us why we are allowed to make such declarations and what are there purposes?

[Maria-discuss] Spider 3.0 is merged against MariaDB 10.0
by Colin Charles 12 May '13

Hi! Kentoku Shiba has merged the latest Spider 3.0 against MariaDB 10.0: https://code.launchpad.net/~kentokushiba/maria/10.0-spider-3.0 I would like to propose this for merging There is also a complete test suite now, and Kentoku has written some instructions: == testing Spider I pushed Spider into "lp:~kentokushiba/maria/10.0-spider-3.0". It's tested on "CentOS 6.3 x86_64" and "Windows 7 professional 32bit". Test command is the followings. > cd mysql-test > ./mysql-test-run.pl --mysqld=--innodb --suite=spider The following test command can't done yet, because it needs some change for MariaDB. > ./mysql-test-run.pl --mysqld=--innodb --suite=spider/bg Spider's background/parallel search feature works allocate and free result-set from data node on different thread, but MariaDB 10.0's "per thread memory usage" feature can't understand it. > ./mysql-test-run.pl --mysqld=--innodb --suite=spider/handler Table partition feature need to support "handler" command. I have a patch file. In addition, it is awesome to note that Kentoku & his team behind the development of Groonga storage engine have also won an award (Japan OSS Incentive Award): http://ossforum.jp/en/node/1277 Thanks cheers, -colin -- Colin Charles, http://bytebot.net/blog/ | twitter: @bytebot | skype: colincharles MariaDB: Community developed.

[Maria-discuss] KB Question: lgpl .net connector
by Daniel Bartholomew 09 May '13

09 May '13

The following question has been posted to the Knowledgebase: https://kb.askmonty.org/en/lgpl-net-connector/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - lgpl .net connector Will there be an lgpl .net connector released in the future? I understand that most mysql downloads are for windows machines which would indicate a large market for mariadb. An lgpl .net connector would be a big incentive for a lot of people to move on MariaDB i think. My company currently use SQL Server but are looking at other options. An lgpl licence for mariadb would be the difference between us moving to mariadb rather than mysql or the liberally licenced postgresql. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Thanks. -- Daniel Bartholomew Google+ - http://gplus.to/dbart Twitter - http://twitter.com/daniel_bart MariaDB: An Enhanced Drop-in Replacement for MySQL Website - http://mariadb.org Twitter - http://twitter.com/mariadb Google+ - http://google.com/+mariadb Facebook - http://fb.com/MariaDB.dbms Knowledgebase - http://kb.askmonty.org

The host defined in the log (10.112.50.145) isn't even one of the local ips of the hosts in the cluster or my severalnines cluster control ip. It keeps incrementing 2 ports and retrying every 5-6 seconds. It's showing the same thing on two nodes in us-east, but nothing in the error log on the us-west-1 node.
