[Maria-discuss] Submitting talks for Percona Live Santa Clara?
by Colin Charles 09 Jan '18

09 Jan '18

Hi all, As part of the program committee, I’m writing in to say we’ve seen only a handful of talks mention MariaDB Server out of the several hundred submissions so far. With all the amazing use cases of MariaDB Server out there, I would expect a lot more. The CFP ends January 12 2018, so please feel free to get ideas and submissions in: https://www.percona.com/live/18/ Kind Regards, Colin Charles -- Colin Charles, http://bytebot.net/blog/ twitter: @bytebot | skype: colincharles "First they ignore you, then they laugh at you, then they fight you, then you win." -- Mohandas Gandhi

[Maria-discuss] Problem with bit operations in certain expressions
by Mats Eklund 09 Jan '18

09 Jan '18

Hi, Need some help here. I have the following expression: SELECT IF(1=1, 0x2, 0x4) | 0x1 which in MySQL evaluates to: 3 but in MariaDB it evaluates to: 1 MySQL's result seems correct to me. Would appreciate any advice on this. Many thanks! Mats

[Maria-discuss] mariadb-connector-c mariadb_config: Faulty output with static gssapi plugin
by Stefan Scherfke 08 Jan '18

08 Jan '18

Hi all, the output of "mariadb_config --libs[_r]" is faulty if the AUTH_GSSAPI plugin is configured as static: I built mariadb-connector-c 3.0.2 on Fedora 26 with this command: mkdir build cd build cmake -DAUTH_GSSAPI=STATIC .. make The output of "mariadb_config" then looks like this: $ mariadb_config/mariadb_config --libs_r -L/usr/local/lib/mariadb/ -lmariadb -lpthread -ldl -lm -lssl -lcrypto -l-lgssapi_krb5 -lkrb5 -lk5crypto -lcom_err All libs should be named like "-l<name>" but gssapi_krb5 has a double "-l-l" prefix. This problems becomes more apparent when I build mariadb-connector-c as a Python Conda package. Without the "AUTH_GSSAPI=STATIC" flag, I get the following libs: -L/opt/emsconda/conda-bld/mariadb-connector-c/env/lib/ -lmariadb -lpthread -ldl -lm -lssl -lcrypto With the "AUTH_GSSAPI=STATIC" flag, I get the following libs: -L/opt/emsconda/conda-bld/mariadb-connector-c/env/lib/ -lmariadb -lpthread -ldl -lm -lssl -lcrypto -l-L/opt/emsconda/conda-bld/mariadb-connector-c/envplaceho/lib -Wl,--enable-new-dtags -Wl,-rpath -Wl,/opt/emsconda/conda-bld/mariadb-connector-c/envplaceho/lib -lgssapi_krb5 -lkrb5 -lk5crypto -lcom_err The problematic part there is the "-l-L/opt/emsconda/.../lib" part which confuses other tools like Mydumper when they are compiled against mariadb-connector-c. Is this an issue with mariadb-connector-c or can I fix it in my build process somehow? Cheers, Stefan

[Maria-discuss] Is this normal behaviour?
by Karthick Subramanian 04 Jan '18

04 Jan '18

All, When I tried to connect in centos 7 mariadb 10.2.11 server using root user, by mistake I gave wrong user name, but it connected successfully. I am not sure why. When I check show databases, it didnt list all DBs, but when I connect with root again, I can see all valid Dbs. Is this normal that even if I give wrong user, it authenticate into DB server from root. [root@ipaddr ~]# mysql -u rot Welcome to the MariaDB monitor. Commands end with ; or \g. Your MariaDB connection id is 22 Server version: 10.2.11-MariaDB MariaDB Server Copyright (c) 2000, 2017, Oracle, MariaDB Corporation Ab and others. Type 'help;' or '\h' for help.

[Maria-discuss] Replication Upgrade Strategy MySQL 5.6 to MariaDB 10.2
by Michael Caplan 29 Dec '17

29 Dec '17

Hello, Am hoping to get some feedback on an upgrade strategy to go from MySQL 5.6 (two separate servers, one replication slave) to MariaDB 10.2 (installed on new servers). I'm looking at an rsync process to seed the two new instances on MariaDB, and am unsure if this is sound (https://www.stephenrlang.com/2016/08/setting-up-mysql-master-slave-replicat…). Roughly, the process would look like this: - rsync data from MySQL 5.6 Master to MariaDB 10.2 Slave - Lock master - Get master status - Refresh rsync - Remove lock - Run upgrade process on MariaDB 10.2 Slave. - Change MASTER.... on MariaDB 10.2 Slave - Create second MariaDB 10.2 Slave from first MariaDB 10.2 Slave - Promote MariaDB 10.2 Slave to Master (redirect all DB traffic at this point) - Redirect other MariaDB 10.2 Slave to new Master - Shutdown MySQL 5.6 servers. What I'm most concerned about is the viability of rsync as a method to seed the new MariaDB server from MySQL 5.6. I've come across some chatter that there are risks using rsync instead of a proper dump and restore. Can anyone comment on this? Thanks, Mike

Hi, Cesar! On Dec 15, Cesar Hernandez wrote: > > Thanks Sergei! > > So the database is encrypted by using AES-128-CBC or AES-128-CRT, right? > Can I use AES-256-CBC? No. Each tablespace is encrypted with a different per-tablespace key. This key is 128 bit. It's generated by encrypting a random 128-bit nonce with the user-specified key. So, if you specify a 256-bit key in the file_key_manager plugin, this 256-bit key will be used to generate the 128-bit tablespace key. The tablespace itself will be encrypted using the 128-bit key.

[Maria-discuss] About data encryption
by Cesar Hernandez 14 Dec '17

14 Dec '17

Hi Can someone tell me which algorithm uses MariaDB when using table encryption? Looking at https://mariadb.com/kb/en/library/data-at-rest-encryption/ <https://mariadb.com/kb/en/library/data-at-rest-encryption/> Seems to talk only about encryption of the key file, but not on the database data. I've been looking for a while and haven't found complete documentation about it. I've even taken a look at the MariaDB source code, in the file /storage/innobase/fil/fil0crypt.cc <http://fil0crypt.cc/> Seems the encryption is done by AES algorithm, but I'm not sure, and I don't know the key size neither the mode of operation. Thanks Cesar
