[Maria-discuss] explain for insert/update/delete
by MARK CALLAGHAN 11 Jul '25

11 Jul '25

Does MariaDB have any plans to support explain for insert/update/delete/replace/CTAS? There have been feature requests open for a very long time on official MySQL without any progress. I have had a few problems in production from 'bad' delete statements that had a very different plan than the select statement with the same where clause. The only way to check for a bad plan today is to use SHOW INNODB STATUS to determine whether the statement locks all rows in a table. http://bugs.mysql.com/bug.php?id=14745 http://bugs.mysql.com/bug.php?id=35355 -- Mark Callaghan mdcallag(a)gmail.com

[Maria-discuss] GRANT PROXY access denied with proxied User
by Fabian Jucker 04 Nov '16

04 Nov '16

Hi, At our enterprise we have a DBA-User proxied with "GRANT PROXY ON 'dba'@'%' TO ''@'%'" and backed by pam module (roughly according to [1]) to login from our ldap-accounts. When logging in via pam into the DBA-Role I'm unable to grant the proxy privileges to other users. Following [2] (MySQL docs, because the MariaDB docs are lacking any further information about this) I already tried to "GRANT PROXY ON 'dba'@'%' TO ''@'%' WITH GRANT OPTION" and "GRANT PROXY ON ''@'' TO 'dba'@'%' WITH GRANT OPTION" (as [2] is ambiguous about if the "proxied_user" or the "proxy_user" should have the "WITH GRANT OPTION"), but neither the first grant nor the second one showed any effect. When I grant the proxy privilege with grant option to a local user, this user is able to grant the proxy privileges to other users. So my question is, if it's not possible to grant proxy privileges while one's logged in with a proxy user? Thanks in advance, Fabian References: [1]: https://mariadb.com/blog/configuring-pam-authentication-and-user-mapping-ma… [2]: https://dev.mysql.com/doc/refman/5.5/en/proxy-users.html

[Maria-discuss] InnoDB plugin maturity
by Ian Gilfillan 01 Sep '16

01 Sep '16

If you look at the list of plugin maturities, say with: SELECT plugin_name,plugin_version,plugin_maturity FROM information_schema.plugins ORDER BY plugin_name; I notice that in 10.1, InnoDB/XtraDB is listed as Gamma (changed from Beta in 10.1.13), while in 10.0, with the same version of XtraDB, it's listed as Stable. What's the basis of the distinction between the two, especially since 10.1 itself is a stable release? It seems strange to have InnoDB listed as the same maturity as Spider :)

[Maria-discuss] Don't replicate procedures in the mysql database
by Игорь Пашев 31 Aug '16

31 Aug '16

Hi all, I'm using multi-source replication with "white list" options only: foo.replicate_wild_do_table = foo.% foo.replicate_ignore_table = foo.beep foo.replicate_ignore_table = foo.tmp The masters are writing row-based binary logs as is (no filtering at masters). This works almost as expected: only the `foo` database gets updates, the mentioned tables are ignored. The `mysql` database does not get updates, even when I run GRANT / REVOKE on the masters quite often. But when I create a procedure on the master it get propagated to the slave: When I execute `CREATE PROCEDURE mysql.bar` on the master, this procedure appears on the slave. How could I avoid that? Did I miss some options? Is this a bug?

Re: [Maria-discuss] Don't replicate procedures in the mysql database

You should keep those procedures in a different database, not mysql. Then you can avoid replication with replication filters: https://mariadb.com/kb/en/mariadb/selectively-skipping-replication-of-binlo… But first, be sure you understand what happens when you call the procedure on the master.

[Maria-discuss] When using the getGeneratedKeys() method the keys are returned, but in which order?
by Péter Éberhardt 26 Aug '16

26 Aug '16

Hi, I want to insert multiple records into a table using one statement like this through jdbc: INSERT INTO demo (name) VALUES ('Jeff'),('Jones'),('Agnes'),...,('Wolfgang'); Then I want to get the generated ids with the getGeneratedKeys() method and match them to the inserted records but how can I be sure the method gives the ids in the same order as I listed the records in the statement? I can't find any related information in the documentation just the fact the method gives back those ids. DDL: CREATE TABLE demo (id bigint primary key auto_increment , name text); If this information would put into the document also then I can go with my implementation on this way. Thanks, Peter

[Maria-discuss] New Question: Locking/deadlocking on temp tables?
by AskMonty KB 26 Aug '16

26 Aug '16

Hello, A new question has been asked in "MariaDB Knowledge Base" by WebtrendsData. Please answer it at http://mariadb.com/kb/en/lockingdeadlocking-on-temp-tables/ as the person asking the question may not be subscribed to the mailing list. -------------------------------- Hello - I am coming up to speed on MariaDB, I have a MS Sql Server and Hadoop background but we are starting to use MariaDB heavily. We have some queries that hit tables with mediumtext datatype columns. My understanding is these types of queries will always generate temp tables directly to disk (because of the text/blob types). I've confirmed our temp table engine is Aria. >From what I've read, in the mysql world, this situation would end up with a MyIsam table on disk, which does not have row locking, only table locking. I've tried looking for info on how Aria tables would handle this as I suspect we are getting deadlocks on these tables. Our application is reporting many database deadlocks, our entire database is all ExtraDB tables, yet SHOW ENGINE INNODB STATUS does not report any deadlocks, which leads me to think it is the temp tables. So I guess my question is, does the Aria engine do row locking? Is it possible to get a status similar to SHOW ENGINE INNODB STATUS? Please forgive me if this is painfully obvious or unclear (I'm still learning!), and thank you for your time. -Aaron -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/lockingdeadlocking-on-temp-tables/

Thanks for your armchair diagnosis, but I'm not "striking out" at anybody. I'm outraged by the behavior of MariaDB. I'm passionate about open source, since my whole life has been spent on it. I joined because the company is open source. What I found after I joined was a total lack of regard for it, and a lack of ethics. Would YOU knowingly ask a customer to install software with known vulnerabilities reported ten years ago? Would you ship open source that doesn't compile? Would you extort your current users of your product for bug fixes? If you answered yes to those questions then you don't have ethics either. --Justin Sent from my iPhone On Aug 25, 2016, at 1:15 AM, Jan Steinman <Jan(a)EcoReality.org> wrote: >> On 2016-08-24, at 06:22, Justin Swanhart <greenlion(a)gmail.com> wrote: >> >> I'm bipolar > > Seems more like Borderline to me.

[Maria-discuss] Backporting bug fixes to 1.0?
by Justin Swanhart 24 Aug '16

24 Aug '16

I have created a GitHub fork of MaxScale which does not include the 2.0 branch. The repository is called GPLScale. There is a big potential problem with this. Take for example the file server/core/utils.c, which now has a new license: https://github.com/mariadb-corporation/MaxScale/blob/2.0/server/core/utils.c This file WAS covered under GPL: https://github.com/mariadb-corporation/MaxScale/blob/cb3213af6382c380df9fc4… When there is a bugfix in 2.0 for server code that existed in 1.0, can that code be backported directly into GPLscale? a) util.c in 2.0 is clearly derivative of 1.0, and is therefore a derivative work of 1.0 and therefore still covered by GPL and b) there is a "violation" of GPL, because 1.0 GPL code is being linked against code covered by an incompatible license (other code in MaxScale). Almost all of the files in MaxScale 2.0 derive from 1.0 so this problem is not just in one file of course. The FSF says that the owner of the software can't legally violate the GPL they can morally violate the GPL. Will MariaDB commit to backporting all bugs in 1.0 code into the 1.0 branch?

Almost all of the files in MaxScale 2.0 derive from 1.0 so this problem is not just in one file of course. The FSF says that the owner of the software can't legally violate the GPL they can morally violate the GPL.

[Maria-discuss] New Question: How to use Maxscale for maximum reliability?

Please answer it at http://mariadb.com/kb/en/how-to-use-maxscale-for-maximum-reliability/ as the person asking the question may not be subscribed to the mailing list. -------------------------------- I'm trying to use Maxscale in front of a Galera cluster. Performance is not an issue. The reason I'm using it is so that I can take down a node for maintenance and upgrades without downtime. But I'm not sure how to achieve this. When I run m my tests I get failures. I suspect that the problem occurs when Maxscale writes to one node and then immidiately tries to read that data from another node. -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/how-to-use-maxscale-for-maximum-reliability/

[Maria-discuss] maxscale 2.0 bug fixes
by Federico Razzoli 18 Aug '16

18 Aug '16

Hi all I see that MaxScale 2.0 will not be open source until 2009.01.01. I have some questions. 1) I expect next releases to fix bugs, including critical and security bugs. When will these versions be open source? 2) At some point MaxScale 2.0 will be open and 3.0 will be released but not open. When a software exists in both an open and a closed source, I expect the open form to be low-quality. This applies to all examples I can think of. I will feel a bit better if you could explain why you will maintain 2.0 for a reasonable number of years. 3) From my understanding part of MariaDB code belongs to Oracle, thus cannot be closed-sourced by you. But what about connectors and some storage engines? Do you plan to change their license? Thanks in advance for your answers. Federico

Re: [Maria-discuss] maxscale 2.0 bug fixes
by Federico Razzoli 17 Aug '16

17 Aug '16

Hi Kaj Yes you did answer all my questions. Thanks for that. I disagree about point 2, precisely the "reasonable number of years" a server software should be supported. Even if a software is very old (say MySQL 5.0 for example) it is very possible that new security holes are found. That's why customers using servers/versions which reached their EOL should definitely upgrade to a more recent version. (yes there are exceptions, but I'm talking about the general case) Let's get back to your example: on 2019.01.02 MaxScale 3.0 could be out and GA. Should we expect the typical user to be ready to upgrade? Based on my experience, definitely not. They need time to decode, plan, test, etc. The possibility that 2.0 will be discontinued (or almost discontinued) immediately after the Change Date is scary, and your answer doesn't provide any guarantees that this won't happen. So, as much as I appreciate your honest answers, and as much as I like the software itself, I am seriously concerned. And also, let me add that I don't like to use a software that is not (yet) open source. I totally understand the problems explained by Monty in his blog post, but I don't like the solution you've found. However I am glad to hear that you don't have plans to do the same changes to connectors and storage engines. If I may give an advice, maybe the Foundation should officially "protect" that software to dissipate any doubt.

MaxScale 2.0 will by then have gone through a list of bug fix releases. I don't expect there to be many bugs left in the MaxScale 2.0 code on 2019-01-02. In a way, what I am saying is that the period until the Change Date is already "a reasonable number of years". What the *exact* situation is on 2019-01-02 depends on how many new releases we will have by then. At any rate, we want to grow the user base of MaxScale. We are interested in large-scale adoption. There won't be much adoption if we don't fix bugs for a "reasonable number of years". All in all, on 2019-01-02, MaxScale 2.0 will be bug-wise of high quality and the only reason to use 2.1 (or 3.0 or whatever) instead of 2.0 will be the added functionality on top of what 2.0 has. So MariaDB Corporation has a high motivation to add desirable functionality. 3) From my understanding part of MariaDB code belongs to Oracle, thus cannot be closed-sourced by you. But what about connectors and some storage engines? Do you plan to change their license? 3. Correct, MariaDB Server cannot be closed sourced by us.

[Maria-discuss] Regarding Automatic fail-over - Maxscale
by Karthick Subramanian 16 Aug '16

16 Aug '16

Hi All, Can anyone help me to figure out this. I am planning to use Binlogrouter for replication (single master and single slave topology). I read from google forums for maxscale that with binlog router, it'snot possible to use automatic failover. Did anyone try this. >From google forum ( https://groups.google.com/forum/#!msg/maxscale/DnFT4eb0BbQ/cHQ3TLEfBAAJ;con… ) "With the 1.3.0 version of MaxScale, the binlogrouter accepts STOP SLAVE, START SLAVE and CHANGE MASTER TO ... commands. These can be used to change the master server but automating this process with the repmgr is not currently possible. Since the binlogrouter supports the normal slave management commands, using something like MHA could be possible: https://code.google.com/p/mysql-master-ha/ " Could anyone help me to understand whether I can use binlog router along with automatic failover feature using maxscale. I have read this blog using shell script we can achieve, but not sure whether with binlog router, it ll work?

[Maria-discuss] Known limitation with TokuDB in Read Free Replication & parallel replication ?
by jocelyn fournier 10 Aug '16

10 Aug '16

Hi, After upgrading from TokuDB Enterprise with MariaDB 5.5 to MariaDB 10.1.14, I tried to enable the parallel replication (parallel_mode=optimistic, slave_parallel_threads=4) on a GTID enabled RFR slave, but it leads to random failures. (both master & slave are running 10.1.14) E.g : Could not execute Update_rows_v1 event on table sc_2.sc_param_index; Can't find record in 'sc_param_index', Error_code: 1032; handler error HA_ERR_KEY_NOT_FOUND; the event's master log mysql-bin.008418, end_log_pos 217608066 If I issue a start slave (with sql_slave_skip_counter=0) : Could not execute Update_rows_v1 event on table sc_2.sc_log_cron; Can't find record in 'sc_log_cron', Error_code: 1032; handler error HA_ERR_KEY_NOT_FOUND; the event's master log mysql-bin.008418, end_log_pos 218275984 If I put back slave_parallel_threads to 0, the slave keeps replicating happily without any issue.

[Maria-discuss] New Question: 2 node replication failover/recovery
by AskMonty KB 03 Aug '16

Hello, A new question has been asked in "MariaDB Community" by greg_brownell_g. Please answer it at http://mariadb.com/kb/en/2-node-replication-failoverrecovery/ as the person asking the question may not be subscribed to the mailing list. -------------------------------- Is there a way to automate the following: 1. 2 node system set up as master-master replication 2. node 1, master 1 fails. 3. node 2 master 2 is now the active instance. Up to here, all works well. Replication is fast enough. We detect failure and code now uses master 2 on node 2. The problem is sync'ing master 1 when the node 1 restarts, perhaps 5 minutes later. Requirement is: 1. node 2 master 2 continues to run without interruption 2. node 1 master 1 must sync as quickly as possible with node 2 master 2 3. this must be done without human intervention (using scripts, programs, whatever) Thanks. -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/2-node-replication-failoverrecovery/

[Maria-discuss] Orphaned TokuDB tables
by Rich Prohaska 02 Aug '16

02 Aug '16

Hello All, Sometimes, TokuDB gets left in a state where it thinks that parts of a table exist (as observed in TokuDB's file map), but not all of the underlying files (the TokuDB data files and/or the frm file) exist. This probably occurs due to the interaction between the non-transactional DDL that MySQL/MariaDB uses to create or drop tables, and the transactional TokuDB engine underneath. There is some bug there. So, what can one do to remove broken TokuDB file maps? There is an internal fractal tree called the tokudb.directory that names high level data names to an underlying file that the data is stored in. The tokudb_file_map information schema dumps out the contents of this tree. The key to this tree is the high level data name (called a dname). In TokuDB, this data name consists of the database name, the table name, and the index name. There is also a tree for the table (called status) that contains table wide metadata. I added the tokudb_delete_dnames_from_directory tool to the https://github.com/prohaska7/mariadb-server/tree/fix-tokudb-filemap branch. This standalone tool can be used to delete dnames from the tokudb.directory. Standalone means that MariaDB must have been previously shutdown cleanly (which puts the tokudb recovery logs in a nice clean state so that the tool does not have to run crash recovery). The input to the tool is the MariaDB data directory with nice and clean tokudb recovery logs along with a sequence of dname's. The tool transactionally deletes rows from the tokudb.directory fractal tree, which updates the recovery logs. Building the tool requires a MariaDB build environment a simple compile sequence something like this: gcc -g -o tokudb_delete_dnames_from_directory tokudb_delete_dnames_from_directory.cc -I$TFT/buildheader -L$TFT/src -ltokufractaltree Running the tool looks something like this: Get the dnames of interest from the tokudb_file_map. In this case, they are ./test/s-main and ./test/s-status. shutdown MariaDB ./tokudb_delete_dnames_from_directory ~/projects/mariadb-server-install/data ./test/s-main ./test/s-status
