[Maria-discuss] User feedback statistics
by Colin Charles 21 Jun '14

21 Jun '14

Hi, http://mariadb.org/feedback_plugin/ in question -- where do we find out information about storage engines in use? List of loaded plugins? So far I see: http://mariadb.org/feedback_plugin/stats/features/ - which has some information but clearly not all information Can we also get access to all the information like if people are using the threadpool or not? I know that information is generated and we're receiving it, but we're just not exposing it (I mean I see this from SELECT * FROM information_schema.feedback;) Its also a good way to see if users are using something like the PERFORMANCE_SCHEMA Let me know how one can access this information (and even better how this can be exposed in the web interface) cheers, -colin -- Colin Charles, Chief Evangelist, SkySQL - The MariaDB Company blog: http://bytebot.net/blog/| t: +6-012-204-3201 | Skype: colincharles

[Maria-discuss] New MariaDB book: Building a Web Application with PHP and MariaDB
by Daniel Bartholomew 18 Jun '14

18 Jun '14

I just received an email from Packt about a new MariaDB book they've just published, Building a Web Application with PHP and MariaDB: A Reference Guide, by Sai Srinivas Sriparasa. If you're interested, check it out: http://www.packtpub.com/building-a-web-application-with-php-and-mariadb/book I was not aware that this book was in the works, so it was a nice surprise! I'm going to pick up a copy, give it a look through, and write up a review on my personal blog. It's been a looong time since I've done anything with PHP (over ten years), so I won't have a lot to say about that part of the content, but I'm reasonably current with MariaDB. ;-) Thanks. -- Daniel Bartholomew, MariaDB Release Manager MariaDB | http://mariadb.com

[Maria-discuss] Easy way to see different users@hosts connected to all databases?
by Tanstaafl 18 Jun '14

18 Jun '14

Is there a simple command I can issue to see a list of the current users@hosts connected to all of the databases of a running mariadb server? I'm trying to troubleshoot a problem where an update from 5.5.30 to 5.5.37 recently caused all of the connections from my groupware host to start coming from a different hostname, and so were being denied. I need to be able to see if changes that I make change the hostname being used. Thanks, Charles

[Maria-discuss] New Question: Does Mariadb has a comparison with PostgreSQL ?
by AskMonty KB 18 Jun '14

18 Jun '14

Hello, A new question has been asked in "MariaDB Documentation" by mayuraviraj: -------------------------------- PostgreSQL maintain a page which compare it with MySQL (https://wiki.postgresql.org/wiki/Why_PostgreSQL_Instead_of_MySQL:_Comparing…) Why not mariadb maintain a such information ? It will be very valuable for DBAs and developers ? Also I think it will help mariadb to evolve in certain new areas with the light of PostgreSQL. -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/does-mariadb-has-a-comparison-with-postgresql/

+ Torben, Dan Hello, DirectFS name has been deprecated and the new name for the Flash aware filesystem from Fusion-io is NVMFS (NonVolatile Memory FileSystem).

[Maria-discuss] Mariadb 10.0.11 "ERROR 2013 (HY000): Lost connection to MySQL server during query". Help fixing?

Guys, i'm with a "newbie" question I need to swap a primary key value, for example: create table test ( id int not null default 0, other varchar(255) not null default '', primary key(id) ); insert into test (1,'a'); insert into test (2,'b'); now i want that (2,'b') becomes (1,'b') and (1,'a') becomes (2,'a') the point is, how to do this, with only one UPDATE without duplicate column id value? and without delete values? -- Roberto Spadim

[Maria-discuss] MariaDB encryption

Hi there, I read this blog post http://monty-says.blogspot.com/2014/05/for-your-eyes-only-or-adding-better.… and wanted to inform you that we at Google has developed on-disk/block-level encryption for Innodb, aria (as used by temporary tables), binlogs and temp-files. The code is not yet published, but we expect it to be within a few weeks or so. We (of course?) think that it would be better if you instead of developing new code spent the time testing/reviewing ours. I'm happy to answer questions on the topic, and will let you know once we've published it. /Jonas ps.

[Maria-discuss] New Question: Spider storage engine condition pushdown
by AskMonty KB 04 Jun '14

04 Jun '14

Hello, A new question has been asked in "Spider" by lokeshkumar-p-417: -------------------------------- Hi, We are using Spider storage engine for sharding with MariaDB. MariaDB version - 10.0.10 Spider version - 3.2 Platform - CentOs 6.5 Problem: ---------------- We have a simple scenario, where we have a table with Spider storage engine, which is list partitioned based on a column. Each partition is pointing to a shard. Whenever a query is fired from the Master database with a WHERE clause, the WHERE condition is not being pushed to the shard, instead all the data from shard is being transferred to the DB where Spider storage engine is present. I came to know that this issue has been fixed in the Spider storage engine, and also I verified the MariaDB 10.0.9-spider-3.2 source code and it has cond_push and cond_pop functions. Please let me know how else can I enable this condition pushdown.

[Maria-discuss] Does the Cassandra storage engine support CQL3 created tables?
by Mohammed Guller 03 Jun '14

03 Jun '14

I am able to access a Cassandra column family created with COMPACT storage directive from MariaDB (v10.0.10). However, it does not seem to recognize regular CFs created using CQL3. I am not sure whether I am missing some configuration step in the Cassandra storage engine or it still does not support regular CQL3 CFs. Has anyone able to make Cassandra SE work with regular CQL3 CFs?

[Maria-discuss] Are queries queued when locking a table?
by Jimmy Thrasibule 28 May '14

28 May '14

Hello, Some backup tools make use of table locking to ensure data consistency during the operation. I'm wondering about what happens to the incoming queries for the table being locked. Obviously, the request will be pending until the table is unlocked but this way some timeout value may be reached. Another option could be to accept and queue all requests and replay them once the table is unlocked. So can you tell me how MariaDB is handling such situation. Is the second option (asynchronous request), can be activated within MariaDB? Best, Jimmy

[Maria-discuss] Role template
by Jimmy Thrasibule 26 May '14

26 May '14

Hi, Roles [1] have been introduced with MariaDB 10.0.5. This feature is very interesting to group and standardize grants in one place. However roles are static, meaning that it is not possible to create a template to apply later on another database. I'm looking for something similar to a stored procedure: CREATE ROLE r1(db); GRANT ALL PRIVILEGES ON $(db).* TO r1; Here, the role takes a parameter we can use to make privileges a bit more dynamic. We can then apply this role on a dedicated database like: GRANT r1(mydb) TO 'myuser'@'localhost'; Can this already be done or do you think that's a feature that could come?

Normally, Spider sends "set sql_log_off" command to remote server after connecting, and this command needs SUPER privilege. For fixing this error, please perform one of the followings. - add SUPER privilege to user for Spider table on remote MySQL 5.5 server. - set Spider options "spider_internal_sql_log_off = 0" and "spider_remote_sql_log_off = 0" in configuration file.

[Maria-discuss] query result inconsistency between MariaDB 10.0.x and Oracle MySQL 5.1.x
by Charles Cazabon 23 May '14

23 May '14

Greetings, I recently upgraded the db server behind an application from MySQL 5.1.73 (as shipped in Ubuntu 10.04 "Lucid") to MariaDB 10.0.11 (from the MariaDB repo). A colleague of mine found an inconsistency between the results produced by the two servers for a given query. What we don't know is, is this a bug (I gather Maria is aiming at 100% compatibility), or is this somehow due to the query relying on unspecified behaviour (that the two db servers are therefore free to optimize differently)? The query is: SELECT t1.id, t2.album_id FROM t1 LEFT OUTER JOIN t2 ON t1.data_id = t2.id AND t1.event_type IN (1002, 1001, 1000) WHERE t1.event_type IN (1000, 1001, 1002, 1200, 1201, 1202, 1203) GROUP BY t1.id ORDER BY t1.id DESC LIMIT 0, 20; The MariaDB result looks like this: +-----+----------+ | id | album_id | +-----+----------+ | 623 | NULL | | 622 | NULL | | 621 | NULL | | 620 | NULL | | 619 | NULL | | 618 | NULL | | 617 | NULL | | 616 | NULL | | 615 | NULL | | 614 | NULL | | 613 | NULL | | 612 | 194 | | 611 | NULL | | 610 | NULL | | 609 | NULL | | 608 | 193 | | 607 | NULL | | 606 | NULL | | 605 | NULL | | 604 | NULL | +-----+----------+ And the Oracle MySQL result looks like this: +-----+----------+ | id | album_id | +-----+----------+ | 623 | NULL | | 622 | NULL | | 621 | NULL | | 620 | NULL | | 619 | NULL | | 618 | NULL | | 617 | NULL | | 616 | 196 |<-- different | 615 | NULL | | 614 | NULL | | 613 | NULL | | 612 | 194 | | 611 | 194 |<-- different | 610 | NULL | | 609 | NULL | | 608 | 193 | | 607 | 193 |<-- different | 606 | NULL | | 605 | NULL | | 604 | NULL | +-----+----------+ My colleague pointed out that if you EXPLAIN the queries, you can see that the two databases are interpreting the query differently -- see the "Extra" column. I can't paste the explain output here without using very long lines, so I've pastebinned it: http://pastebin.com/n2sbH0kY My colleague has made the data from these tables available here: https://dl.dropboxusercontent.com/u/7755033/fatdrop/test_case_data.sql We've found workarounds for this, but we're really wondering if we've found a problem (either in MariaDB-MySQL consistency, or in the query, or ... ?). Any assistance appreciated.

[Maria-discuss] Rollback from 10 to 5.5 with WHM

Hi, I installed MariadB 10 but was seeing poor performance and query times, so I rolled back to Mysql and saw better results. I wanted to rollback to Mariadb 5.5 but when going through the steps at http://blog.cpanel.net/mysql-mariadb/ and having the 5.5 repo in my Yum repos lists, it still tries to install MariaDB 10. Does anyone know why or how I can install 5.5 on WHM after installing and removing 10? Cheers Dan

[Maria-discuss] Merging FusionIO changes to 10.0.12

Hi all, MariaDB has worked actively with Fusion-io, and we did release some improvements in a preview release a little over a month ago: https://blog.mariadb.org/significant-performance-boost-with-new-mariadb-pag… This was originally planned to be included into 10.0.10, but when we released the GA, we thought that the feature was not tested thoroughly. Now the code has proven stable we are thinking of merging this into 10.0.12. Yes, we know its already a GA, but this feature will be turned off by default, and the code is safely encapsulated. If you are not using Fusion-io or do not turn it on, there is no effect to you. To check, the changes are in the XtraDB and InnoDB that we ship (storage/xtradb & storage/innobase). Naturally, for those using Fusion-io devices, the benefits are clear - you will see significant improvements in speed and you will increase the lifetime of your cards.

[Maria-discuss] Help with history tables

Hi guys I have an doubt about design I have a history table: CREATE TABLE HISTORY( CHANNEL INT NOT NUL DEFAULT 0, HISTORY_DATE DECIMAL(22,6) NOT NULL DEFAULT '0' COMMENT 'UNIX TIME', VALUE DECIMAL (22,6) NOT NULL DEFAULT 0, PRIMARY KEY (CHANNEL,HISTORY_DATE) ) my question is... i need a history of only 50000 rows for each channel what's the best method to allow a good history without many deletes, analyse tables, and others stuffs to allow a good table/disk usage? i was considering a counter, for example, after 1000 inserts, run a SELECT COUNT(*) FROM HISTORY WHERE CHANNEL={channel_id} get this number of rows, if it's > 50000 run: DELETE FROM HISTORY WHERE CHANNEL={channel_id} ORDER BY HISTORY_DATE ASC LIMIT (number_of_rows - 50000) any other idea? maybe a 'batch' operation? i was think about something like (don't work, just a idea) DELETE FROM HISTORY WHERE CHANNEL IN (channel numbers) AND xxxxx? LIMIT 50000 GROUP BY CHANNEL i don't know anything to group by channel id and delete rows using only one sql command , any idea? thanks guys! -- Roberto Spadim SPAEmpresarial Eng.

Hi gerry, You asked why TokuDB and SphinxSE isn't in stock MariaDB that you get from Ubuntu 14.04, and I shall attempt to answer that for you (Ubuntu packages are inherited from upstream Debian fwiw) From /etc/lsb-release: DISTRIB_DESCRIPTION="Ubuntu 14.04 LTS" select version() gives: 5.5.37-MariaDB-0ubuntu0.14.04.1 When I do show engines; I see Sphinx: | SPHINX | YES | Sphinx storage engine | NO | NO | NO | You can verify it exists in /usr/lib/mysql/plugin. By default, there are 11 "engines" listed If you follow https://mariadb.com/kb/en/how-to-enable-tokudb-in-mariadb/ you may be disappointed not to see TokuDB (since it appeared in 5.5.33 - simple answer is that its disabled, just like oqgraph See commit: http://anonscm.debian.org/gitweb/?p=pkg-mysql/mariadb-5.5.git;a=commit;h=68… You can however continue to get TokuDB from our mariadb repositories, using the repository config tool HTH cheers, -colin -- Colin Charles, Chief Evangelist, SkySQL - The MariaDB Company blog: http://bytebot.net/blog/| t: +6-012-204-3201 | Skype: colincharles

[Maria-discuss] SELinux policy for MariaDB/Galera?
by Franz Schwartau 14 May '14

14 May '14

Hi! I'm looking for a SELinux policy for MariaDB/Galera. I'd like to use MariaDB/Galera with enforcing targeted SELinux. I googled a lot. No real solution showed up. The most helpful page was https://groups.google.com/forum/#!topic/percona-discussion/beyXK3U0ySo/disc… which solves part of the problem. Currently I try to allow SST via rsync. /usr/bin/wsrep_sst_rsync executes ps and netstat producing a lot of AVC denials, e. g. ---- time->Wed May 14 10:30:23 2014 type=SYSCALL msg=audit(1400056223.334:70): arch=c000003e syscall=4 success=yes exit=0 a0=17081b0 a1=7f9811231ca0 a2=7f9811231ca0 a3=17081b6 items=0 ppid=1678 pid=1704 auid=4294967295 uid=497 gid=498 euid=497 suid=497 fsuid=497 egid=498 sgid=498 fsgid=498 tty=(none) ses =4294967295 comm="ps" exe="/bin/ps" subj=system_u:system_r:mysqld_t:s0 key=(null) type=AVC msg=audit(1400056223.334:70): avc: denied { getattr } for pid=1704 comm="ps" path="/proc/844" dev=proc ino=10578 scontext=system_u:system_r:mysqld_t:s0 tcontext=system_u:system_r:initrc_t:s0 tclass=dir ---- time->Wed May 14 10:30:23 2014 type=SYSCALL msg=audit(1400056223.337:75): arch=c000003e syscall=2 success=yes exit=12 a0=7f9811231840 a1=0 a2=0 a3=0 items=0 ppid=1678 pid=1704 auid=4294967295 uid=497 gid=498 euid=497 suid=497 fsuid=497 egid=498 sgid=498 fsgid=498 tty=(none) ses=4294967295 comm="ps" exe="/bin/ps" subj=system_u:system_r:mysqld_t:s0 key=(null) type=AVC msg=audit(1400056223.337:75): avc: denied { open } for pid=1704 comm="ps" name="stat" dev=proc ino=12305 scontext=system_u:system_r:mysqld_t:s0 tcontext=system_u:system_r:restorecond_t:s0 tclass=file type=AVC msg=audit(1400056223.337:75): avc: denied { read } for pid=1704 comm="ps" name="stat" dev=proc ino=12305 scontext=system_u:system_r:mysqld_t:s0 tcontext=system_u:system_r:restorecond_t:s0 tclass=file type=AVC msg=audit(1400056223.337:75): avc: denied { search } for pid=1704 comm="ps" name="1230" dev=proc ino=12150 scontext=system_u:system_r:mysqld_t:s0 tcontext=system_u:system_r:restorecond_t:s0 tclass=dir audit2allow doesn't help in this case. The target domain isn't "fixed". It depends on the processes running. "netstat -lnpt" executed by /usr/bin/wsrep_sst_rsync has the problem. How could I write a SELinux policy to allow access for ps and netstat? Is there an "official" policy? Even RHEL 7 hasn't support for Galera (but improves the mysql policy for MariaDB a bit). Best regards Franz

[Maria-discuss] libaio dependency?
by Benjamin Jaton 12 May '14

12 May '14

Hi, I downloaded this archive: mariadb-10.0.10-linux-x86_64.tar.gz I use the simple my.conf from the documentation but all the commands fail, saying that they need libaio. *$ ./scripts/mysql_install_db --defaults-file=./my.conf Installing MariaDB/MySQL system tables in '(...)/var' ..../bin/mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directoryInstallation of system tables failed! Examine the logs in (...)/var for more information.* I think this used to be a bug in 5.5.23 ( https://mariadb.atlassian.net/browse/MDEV-302 ), can it be in 10.0.10 as well? Thanks, Ben

[Maria-discuss] MariaDB 10.0.10 - InnoDB confusion?
by Charles Cazabon 08 May '14

08 May '14

Greetings, I'm not sure if I'm doing something particularly stupid, but I'm having difficulty using InnoDB (the XtraDB version) with MariaDB v.10.0.10. The engine shows as disabled in my configuration for reasons I'm unclear on. I'm using a mirror of the apt repository (from http://mariadb.org/mariadb/repositories/) on Ubuntu 14.04 server, running on x86_64. The currently installed version is 10.0.10+maria-1~trusty . My configuration includes changing the default table type: # defaults to innodb default_storage_engine = aria That works as expected. However, when I create a table specifying `ENGINE=InnoDB`, the table is actually created as an Aria table, and a warning is logged: > show warnings; +---------+------+---------------------------------+ | Level | Code | Message | +---------+------+---------------------------------+ | Warning | 1286 | Unknown storage engine 'InnoDB' | +---------+------+---------------------------------+ Sure enough, the InnoDB engine shows as not supported: > show engines; [...] | InnoDB | NO | Percona-XtraDB, Supports transactions.... | I haven't done anything specifically to disable XtraDB/InnoDB support. Looking through the documentation, knowledge basse, and mailing list archives hasn't turned up anything related. The only thing I found was this, in the documentation for the ignore_builtin_innodb variable: ignore_builtin_innodb Description: In older versions of MariaDB, setting this to 1 resulted in the built in InnoDB storage engine to be ignored. In MariaDB 5.5, InnoDB is the default and is always present, so this variable is ignored and setting it results in a warning. In MariaDB 10.0.x, this variable currently needs to be set. I'm not sure exactly what it means by saying it "needs to be set" with this version of MariaDB (doc bug?). If I add `ignore_builtin_innodb = 1` to my configuration, then the server refuses to start, complaining about unrecognized configuration options in the config, basically anything to do with innodb (innodb_file_per_table, innodb_checksum_algorithm, etc). Am I missing something? Is there a way to use Aria as the default table type while still allowing the use of XtraDB-provided InnoDB tables as well? Any assistance appreciated.
