[Maria-discuss] MariaDB Fedora update - testing
by Michal Schorm 30 Jan '17

30 Jan '17

Hello everybody, I made a (form my POV) bigger change to how MariaDB is packed, and I would be grateful for any feedback. I separated all the non-essential utilities to a standalone sub-package "server-utils". It should be installed automaticly with the "server" package as a weak dendency, so regular user should not spot any change. For example, if you don't need Perl with your server, you can save about 20MB of the space with this update. Rawhide: https://koji.fedoraproject.org/koji/taskinfo?taskID=17426872 F25: https://bodhi.fedoraproject.org/updates/FEDORA-2017-0f44f2b8c8 F24: https://bodhi.fedoraproject.org/updates/FEDORA-2017-801e01d1ed Thanks for any feedback in an advance! -- Michal Schorm Core Services - Databases Team mail: mschorm(a)redhat.com Brno-IRC: mschorm

[Maria-discuss] question about generating logs on MariaDB 10.1.21
by Chris Adams 25 Jan '17

25 Jan '17

Hello, I have just moved from a MySQL 5.6 server on CentOS 6.8 to a MariaDB 10.1.21 server on CentOS 7. It is installed and working. I would like to set up some logging, but it has not gone as expected. I have binary logging working. However, I can't generate general logs or error logs. Here is part of the /etc/my.cnf file: user=mysql port = 3306 socket = /var/lib/mysql/mysql.sock datadir = /mnt/mysqldbs log_error = /var/log/mysql/error.log general_log_file = /var/log/mysql/mysql.log general_log = 1 log_bin = /mnt/mysqldbs/logs/mysql-bin I assume that after a restart, the logs will be generated, then logged to as events happen. As it is, no log files are generated. Many thanks.

[Maria-discuss] LTO build fails likely because -static-libgcc
by Reindl Harald 22 Jan '17

22 Jan '17

why does MariaDB use "-g -static-libgcc" in "mysql_release.cmake" and so besides override -g0 break -flto builds?
