[Maria-discuss] Serious problem with latest (10.0.16) Windows installer - destroys services.
by Peter Laursen 02 Mar '15

02 Mar '15

I have MariaDB 5.5, 10.0 and 10.1 installed (as Windows services named 'maria55'. 'maria10' and 'maria10_1' ) and always update them to latest soon after an update is available. Yesterday morning I installed 10.0.16 on top of 10.0.15 using the .msi installer. When I tried to connect to it a few hours later it was not possible. I thought the service might not be running. It wasn't. Actually it did not exist anymore at all! "net start maria10" returned "service does not exist" (and indeed it did not appear in Windows "services management" interface). I copied the /datadir, uninstalle , did a fresh install of 10.0.16d (choosing the option not to upgrade any existing server) and copied the old /datadir back. Now Maria 10.0(.16) works again. But now I see that the 'maria55' service is also gone from the system. Files are intact. I can repeat the exercise I did with 10.0 of course or install service again from commandline. Not a big problem, but very annoying and waste of time. MariaDB 10.1 installaton is not affected. 5 diiferent Oracle/MySQL servers (from 5.0 to 5.7) also are not. I need all those instances for application testing. Questions: * Has somebody else experienced this? * Has somebody replaced @wlad as maintainer of Windows installers? @wlad was the only person who ever was able to write reasonable MySQL/MariaDB installers. So I would regret that. It is perfectly legal on Windows to have multiple MariaDB servers simultaneously running as Windows services. They won't conflict as long as service name, port, basedir and datadir are all different. What happens with one should not affect another. I the installer does not respect this, it is a bug. -- Peter -- Webyog

[Maria-discuss] Giving up on dynamic columns
by Tom Worster 02 Mar '15

02 Mar '15

I discovered this showstopper on Friday while working with real data in development of a new app. I managed to narrow it down today and filed the bug report. https://mariadb.atlassian.net/browse/MDEV-7650 Looks like Maria saves an illegally formatted dyncol string if a dynamic column is longer than 64kB and is not alphabetically last by name among the dynamic column in the blob. Tbh, even is this were fixed tomorrow so I could proceed with my work, I'm not sure I would use dyncols. My confidence in the feature has been shaken. It's a pity because the Active Record ORM extension I wrote was working. Tom

[Maria-discuss] myisam_use_mmap unstable in MariaDB 10.0.x
by Reindl Harald 01 Mar '15

01 Mar '15

historical: http://lists.mysql.com/mysql/226361 after it turned out to be stable in 2013/2014 upgrade to MariaDB 10.0.17 yesterday and the logs started with "table corrupt", "table not closed properly" and so on for tables which where not only read this time not with 'mysqld got signal 11' but "only" corrupted MyISAM files and after disable 'myisam_use_mmap' all is clean and stable over hours BTW a 'repair table' don't delete the TMM file leading in a 'optimize table' later failing until you delete the file manually from disk __________________________________________________________________ this configuration is unchanged for years and so my only conclusion is that Oracle managed to kill the feature again, this is also confirmed for Percona Server 5.6 where even queries fail confirmed from another sysadmin which found out that playing with my settings leaded to problems while here MariaDB 5.5.x was in use and hence no troubles - given that 'myisam_use_mmap' is borked at MariaDB 10.x and Percona 5.6 it's likely a backport from MySQL 5.6 delay-key-write = ALL concurrent_insert = 2 open-files-limit = 750000 myisam-recover-options = "FORCE" myisam_use_mmap = 0 wait_timeout = 300 interactive_timeout = 300 max_allowed_packet = 200M max_connections = 500 max_tmp_tables = 150 max_connect_errors = 250 max_delayed_threads = 32 flush_time = 0 query_cache_limit = 256K query_cache_min_res_unit = 1K query_cache_size = 1280M query_cache_type = 1 table_cache = 10000 table_definition_cache = 10000 thread_cache_size = 400 tmp_table_size = 256M max_heap_table_size = 256M key_buffer_size = 256M sort_buffer_size = 256K myisam_sort_buffer_size = 15M join_buffer_size = 1M preload_buffer_size = 128K read_buffer_size = 128K read_rnd_buffer_size = 128K

[Maria-discuss] warning from binary tarball file installation.

I am installing mariadb-10.0.15 on Fedora 20 from a binary tarball file. After several changes on .my.cnf file, I minimized the installation warning to three.

[Maria-discuss] Default privileges for anon. user.
by dE 26 Feb '15

26 Feb '15

Hi! I've realized that by default MariaDB allow full access to a database for anon. users. $ mysql --user asdfasdf test MariaDB [test]> insert into test (sr) values (1); Query OK, 1 row affected (0.12 sec) I tried to revoke but -- Revoke all on test.test from ''@''; ERROR 1141 (42000): There is no such grant defined for user '' on host '%' Is there anyway to disallow all types of access to anon. users?

[Maria-discuss] questions from a new user
by Peter Boston 25 Feb '15

25 Feb '15

I am new to use mariadb on linux machine. I am using Fedora 20 and I have downloaded the mariadb 10.0.15 tar.gz file and its instruction. I removed the existing mariadb from my Fedora 20. I have installed the mariadb on my machine by following the official instruction. It seems successful (without error) but I cannot start it as expected. I also have few other basic questions. Some background information here: this database will be accessed by a local application. This local application may be running under a general user account, user1. I installed it in /var/local as a root user. Questions: 1. How to uninstall it completely? I want to try again to see if I did anything wrong before. 2. Because it will be accessed by a local application and the local application will be running by a general user, user1, should I install it with user1? 3. Basically I am confused with these three users: user1, mysql and root. "user1" will be used to run the application and login the machine. "mysql" will be used to connect the mariadb. "root" will be used to install mariadb into /usr/local. Who will start the mariadb? It will be "root", I guess. But if "root" starts the service, "user1" and "mysql" don't have problem to access its resources? 4. If I don't want to install it as root, can I still install it under the /usr/local directory? 5. I renamed the my-large.cnf to .my.cnf and uncomment the InnoDB table section. Is this only change I need to make if I want to use InnoDB? should I disable the myisam? how? 6. where should I put the .my.cnf file? put into the home directory of the user who starts the mariadb or the user who logon the system if they are different? 7. there is a my.cnf file from the Fedora 20 installation, when I start mariadb without the "--defaults-file=~/.my.cnf" option, I will get the following error from the log: [ERROR] mysqld: Can't create/write to file '/var/run/mysqld/mysqld.pid' (Errcode: 2 "No such file or directory") I have to manually create the mysqld folder inside the /var/run folder each time after reboot. how to avoid this? 8. After started with that "old" my.cnf, I try to stop the mariadb but cannot because I cannot find its service name: [user1@dev2 mysql]$ ./bin/mysqladmin -u root -p status Enter password: Uptime: 685 Threads: 1 Questions: 3 Slow queries: 0 Opens: 0 Flush tables: 1 Open tables: 62 Queries per second avg: 0.004 [user1@dev2 mysql]$ sudo systemctl status mariadb.service mariadb.service Loaded: not-found (Reason: No such file or directory) Active: inactive (dead) [user1@dev2 mysql]$ sudo systemctl status mysql.service mysql.service Loaded: not-found (Reason: No such file or directory) Active: inactive (dead) [user1@dev2 mysql]$ sudo systemctl status mysqld.service mysqld.service Loaded: not-found (Reason: No such file or directory) Active: inactive (dead) how stop it? 9. if I start mariadb with the renamed my-large.cnf ([root@dev2 mysql]# ./bin/mysqld_safe --defaults-file=~/.my.cnf --user=mysql), I got the following error: 150225 0:09:28 [ERROR] Can't open the mysql.plugin table.

[Maria-discuss] SHOW GRANTS: MySQL vs. MariaDB
by Felipe Gasper 24 Feb '15

24 Feb '15

Hi all, We have custom logic in place that “suspends” a MySQL user by: - reversing the password hash - replacing the leading “*” with “-” In other words (pseudo-code): my $hash = SELECT password FROM mysql.user WHERE user = 'theuser'; $hash = $hash.replace(/^\*/,"").reverse(); UPDATE mysql.user SET password = "-$hash" WHERE user = 'theuser'; I have noticed that MySQL’s SHOW GRANTS reports these “suspended” password hashes with the leading dash “fixed” to a leading asterisk. MariaDB 10, though, has SHOW GRANTS report the literal contents of mysql.user. Is this behavior by design in MariaDB 10? Is it behavior that we can depend on moving forward? -FG
