[Maria-discuss] MariaDB Compile Size
by Tom Jay 21 May '18

21 May '18

Hello, Has anyone got any idea how to reduce the MariaDB install size, when compiling from source? I've had multiple attempts, all with different options such as 'WITHOUT_EXAMPLE_STORAGE_ENGINE=1' and 'FEATURE_SET:STRING=large', for example, but with no effect. The installation size is usually around 2.1 GB, whereas the official Arch package, which also compiles from source, is about 231.78 MB. The official Arch build script is here [https://git.archlinux.org/svntogit/packages.git/tree/trunk/PKGBUILD?h=packa…] and the only difference I can notice is that they delete a lot of stuff afterwards. Is there any reference for stuff that can be deleted after MariaDB has been installed? Thanks.

Hello, I realize that in general replication from a newer master to an older slave is typically not recommended. This said, does anyone have an experience replicating from MariaDB 10.2 to MySQL 5.6? The compatibility matrix found here: https://mariadb.com/kb/en/library/mariadb-vs-mysql-compatibility/ Seems to be missing data on this type of setup. Thanks, Mike

[Maria-discuss] Backing up a single database with mariabackup?
by Kevin Poitra 01 Mar '18

01 Mar '18

I've been working on redoing our database backup routines, and have looked into mariabackup as mysqldump doesn't cut it anymore given the size of our schemas. We have multiple schemas that need to be backed up - they all vary in size, and they also vary in backup frequency (some need to be backed up on a six hour period, others can go a day in between backups). On top of that, our database consists of two database servers, running in a master-slave configuration. To start, I ran this command against one of our schemas: mariabackup --backup --user root --password <pass> --databases db1 That generated a copy of the 'db1' schema's data files, along with some files used by MariaDB itself (aria_log, ib_buffer_pool, ib_logfile, ibdata, so on). This works perfectly - we can create separate backups of each of our schemas. Restoring seems to be another story however. After '--prepare'ing the backup and issuing the mariabackup --copy-back command, it complains that the data directory must be empty. If I have separated backups, would it be possible for me to restore those schemas under one database (or rather, one MariaDB instance)? To be even clearer, if I've made backups of schemas 'db1', 'db2', and 'db3', I don't seem to be able to restore them all under the same database instance - is there something I'm not understanding?

To support automatic key rotation every key additionally might have different versions. XtraDB and InnoDB can automatically re-encrypt the data from an older to a newer version of the same key. But how different keys are stored and rotated depends on the key management solution that you choose. but for this plugin file_key_management This plugin does not support key rotation — all keys always have the version 1. So I understand that I can't rotate the keys similar to what the AWS plugin provides. But if I need to change the key at any time, either just its encrypted form /etc/mariadb/keys.enc &/or the 'master' /etc/mariadb/keys.txt What's the procedure to re-key all the encrypted tables? Do I need to (1) stop the server (2) manually decrypt each table with its old key (3) reencrypt each table with the new key (4) restart the server ? True also for having used multiple keys for global/default, temp tables, and per-table? Is there any tool/procedure that automates that? I suppose that the AWS plugin takes care of that automated-rotation. Is there another non-commercial/open-source plugin with similar rotation capability?

[Maria-discuss] JSON column type
by Brent Clark 22 Feb '18

22 Feb '18

Good day Guys I have a client that is looking for JSON support, or better 'JSON column type'. He is asking for MySQL/5.7.8 (Currently on MySQL 5.6). And his comment is : "/This is so that we can use the JSON column type introduced in this version." We don't use MySQL, well we shipping away to MariaDB. The question I would like to ask is. Based on reading : https://mariadb.com/resources/blog/best-both-worlds-relational-json Is it fair to say, the clients needs are met? If anyone has any comment or further thought on this matter or any tips to share it would gratefully be appreciated. Regards and many thanks. Brent Clark

[Maria-discuss] mysqld_safe

I did an update on my package manager and it seems that mysqld_safe was removed from the system, and I have that integrated into my openrc init system. Has it stopped being supported? ruben -- So many immigrant groups have swept through our town that Brooklyn, like Atlantis, reaches mythological proportions in the mind of the world - RI Safir 1998 http://www.mrbrklyn.com DRM is THEFT - We are the STAKEHOLDERS - RI Safir 2002 http://www.nylxs.com - Leadership Development in Free Software http://www2.mrbrklyn.com/resources - Unpublished Archive http://www.coinhangout.com - coins! http://www.brooklyn-living.com Being so tracked is for FARM ANIMALS and and extermination camps, but incompatible with living as a free human being. -RI Safir 2013

Yes, I guess. It'll be consistent with what we do with the server. Of course, if you also have a solution how to reduce the number of packages, that'd be perfect :) Hmm, how about that? We rename the following packages to remove "-10.1" at the end. mariadb-connect-engine-10.1 mariadb-oqgraph-engine-10.1 mariadb-cracklib-password-check-10.1 mariadb-gssapi-server-10.1 mariadb-gssapi-client-10.1 mariadb-backup-10.1 This way the server package will specify the version (either "mariadb-server-10.1" for 10.1 or "mariadb-server" for the latest) and everything else will follow. Looks logical and doesn't increase the number of packages (!!!). But I need to try whether it'll actually work in Debian :) Regards, Sergei Chief Architect MariaDB and security(a)mariadb.org

I am not sure this is a good idea. Having a meta-package for the server and not one for mariabackup may seem inconsistent, but users are different. A lot of people just want MariaDB and don't (need to) care about versions. Maybe they barely know SQL and just want to run a simple script. For backups, it's different. If you need mariabackup you manage a MariaDB instance, and you need to care about versions.

My message was just a suggestion, to have a "meta-package" for Debian repository, like we have a meta-package "mariadb-server" that points to "mariadb-server-10.2" (for example, if you installed 10.2 repository).

Hi, Benjamin! First: please send questions like this to maria-discuss(a)lists.launchpad.net it's a public mailing list dedicated to MariaDB. I am subscribed, so I'll see you mail there, and you may be sure I will, because it won't be accidentally catched by my spam filter, or sorted out in some obscure folder. Furthermore other subscribers will see your question and could reply if I will be not available (e.g. I could be travelling). Thank you.

It is intentional, to protect the integrity of the history. SQL Standard, as far as I know, does not provide any way of falsifying the history of system versioned tables. There is another feature in the standard: application-time period tables, in there one can provide arbitrary values for start and end timestamps. But MariaDB 10.3 doesn't support application-time period tables. As for backups, yes, I agree, it's a problem. Binary backups will preserve the history just fine, but mysqldump backups will not, they'll reset the history. > 2. What is supposed to be done in 2038 when NOW() will surpass the ROW > END column?

We don't have any solution specific to system versioned tables. I could *guess* that closer to that date TIMESTAMP width will be increased and, perhaps, there will be some migration procedure in mysql_uprade. There are no specific plans yet.

[Maria-discuss] [MARIADB 5.5] Profiling truncated
by Fabien CLERC 12 Feb '18

12 Feb '18

Hello, I'm trying to profile a very long query in production (MariaDB 5.5) using "set session profiling = 1" but when I run the command "show profile for query 1", there is only the only 100 last steps of the query. It's the same checking in "INFORMATION_SCHEMA.PROFILING" I understand the parameter "profiling_history_size" is the maximum number of queries and not the maximum steps stored fora query. => How can I change the number of steps available in the result of the profiling ?

[Maria-discuss] Clarification about have_ssl and have_openssl variables
by Peter Laursen 11 Feb '18

11 Feb '18

MySQL documentation states https://dev.mysql.com/doc/refman/5.7/en/server-system-variables.html#sysvar… simply states "This variable is an alias for have_ssl.". I checked with a few Oracle/MySQL installations that the two variables have identical values. But this is not the case on MariaDB (I checked my local Windows installs of 10.1 and 10.2). have_openssl is NO - have_ssl is YES|DISABLED. We believe that this is the reason for a newly reported problem to us: SSL-connections is not possibe to MariaDB on Amazon RDS. We verified the problem with a fresh RDS instance with MariaDB 10.2 and running with SSL enabled. The 3 different 'mysql' CLI's give results: *MariaDB 10.2.6 version:* - without ssl, gives 'Access denied error' - with ssl, it gives Error No. 2026: SSl Connection error: Certificate signature check failed *using MySQL 5.7.x version:* it connects to the server irrespective of the ssl parameter passed or not (but we don't know if SSL is actually used. It may silently connect without SSL if SSL is not possible) *MariaDB 10.1.22 version:* without ssl: it gives 'Access denied error' with ssl (Works as expected) Any thoughts on this? What can we do? We are affected as we use MariaDB Connector/C 2.33 currently -- Peter -- Webyog

[Maria-discuss] Triangular FKs - Cascade delete leaves DB in state with broken referential integrity
by Oliver Schonrock 05 Feb '18

05 Feb '18

I have come across a very strange symptom with triangular FKs (see below) where a cascade delete of the central (member) record leaves the DB in a state with broken referential integrity. The FK structure is a little bit demanding and somewhat "triangular/circular", but has been in operation in our application for many years without problems. After recent upgrade from 10.1 to 10.2.12, we promptly got broken FKs. (I have not yet retested with 10.1). How to reproduce: (example reduced to the bare essentials with 3 tables with 1 record each). SET FOREIGN_KEY_CHECKS=0; CREATE TABLE member ( id int(11) NOT NULL AUTO_INCREMENT, default_address_id int(11) DEFAULT NULL, default_card_id int(11) DEFAULT NULL, PRIMARY KEY (id), KEY member_FI_2 (default_address_id), KEY member_FI_3 (default_card_id), CONSTRAINT member_FK_2 FOREIGN KEY (default_address_id) REFERENCES address (id) ON DELETE SET NULL ON UPDATE CASCADE, CONSTRAINT member_FK_3 FOREIGN KEY (default_card_id) REFERENCES payment_method (id) ON DELETE SET NULL ON UPDATE CASCADE ) ENGINE=InnoDB; INSERT INTO member VALUES (1,2,3); CREATE TABLE address ( id int(11) NOT NULL AUTO_INCREMENT, member_id int(11) NOT NULL, PRIMARY KEY (id), KEY address_FI_1 (member_id), CONSTRAINT address_FK_1 FOREIGN KEY (member_id) REFERENCES member (id) ON DELETE CASCADE ON UPDATE CASCADE ) ENGINE=InnoDB; INSERT INTO address VALUES (2,1); CREATE TABLE payment_method ( id int(11) NOT NULL AUTO_INCREMENT, member_id int(11) NOT NULL, cardholder_address_id int(11) DEFAULT NULL, PRIMARY KEY (id), KEY payment_method_FI_1 (member_id), KEY payment_method_FI_2 (cardholder_address_id), CONSTRAINT payment_method_FK_1 FOREIGN KEY (member_id) REFERENCES member (id) ON DELETE CASCADE ON UPDATE CASCADE, CONSTRAINT payment_method_FK_2 FOREIGN KEY (cardholder_address_id) REFERENCES address (id) ON DELETE SET NULL ON UPDATE CASCADE ) ENGINE=InnoDB; INSERT INTO payment_method VALUES (3,1,2); SET FOREIGN_KEY_CHECKS=1; SELECT * FROM member; +----+--------------------+-----------------+ | id | default_address_id | default_card_id | +----+--------------------+-----------------+ | 1 | 2 | 3 | +----+--------------------+-----------------+ SELECT * FROM address; +----+-----------+ | id | member_id | +----+-----------+ | 2 | 1 | +----+-----------+ SELECT * FROM payment_method; +----+-----------+-----------------------+ | id | member_id | cardholder_address_id | +----+-----------+-----------------------+ | 3 | 1 | 2 | +----+-----------+-----------------------+ DELETE FROM member WHERE id = 1; SELECT * FROM member; [ empty ] SELECT * FROM address; [ empty ] SELECT * FROM payment_method; +----+-----------+-----------------------+ | id | member_id | cardholder_address_id | +----+-----------+-----------------------+ | 3 | 1 | NULL | +----+-----------+-----------------------+ ------------ DB is now in an inconsistent state: payment_method.member_id=1 references a non-existent member record.

[Maria-discuss] Aurora 'rds.amazonaws.com' string detection
by Evan Burke 31 Jan '18

31 Jan '18

Hi, I recently resolved an issue with an application using the MariaDB JDBC driver being unable to connect to an Amazon Aurora MySQL-compatible database (single instance, not cluster). This turned out to be caused by using 'dblink.[examplehostname].com' for my Aurora connection string, rather than the ...rds.amazonaws.com string checked for in UrlParser.java - https://github.com/MariaDB/mariadb-connector-j/blob/386819936ffad08d0ac2134… I see the code comment indicating that there are problems with detecting Aurora via other methods, as well as compatibility issues preventing the ability to connect to Aurora without a special case, so to some extent I can understand the decision to use hostname or haMode detection. But I wanted to point out that this approach comes with downsides - particularly when it is not documented anywhere that I can see. We had to review the code itself on Github in order to identify the solution, and that's a problem. While I don't expect my experience to be the same as most users, I can't be the only one using an alternate hostname or an IP address to connect, or the only one making the reasonable assumption that the driver is hostname-agnostic. The other consideration - which I am admittedly making somewhat naively - is that the MySQL JDBC driver is able to connect to this Aurora instance without any problems, regardless of hostname. From the perspective of an end user who doesn't care too much about implementation details, I'm probably going to prefer the option that doesn't exhibit unexpected behavior. In any case - despite the frustrating experience I had - I am grateful to everyone who's contributed to the MariaDB project, and I hope my feedback is helpful. -Evan

[Maria-discuss] Fwd: mysql_insert_id() for INSERT...SELECT statement
by Yuki . 30 Jan '18

30 Jan '18

Hi, I made a post at https://stackoverflow.com/questions/48306962/mysql- insert-id-for-insert-select-statement, but have not received any helpful answer, may be you could help me. I am using MaridDB but I read MySQL documentation because it has much more elaborated documentation than the same page for MariaDB. I am doing similar INSERT...SELECT query to this INSERT INTO table (value1, value2) SELECT 'stuff for value1', 'stuff for value2' FROM DUAL WHERE NOT EXISTS (SELECT * FROM table WHERE value1='stuff for value1' AND value2='stuff for value2') LIMIT 1 , where table has auto-genrated id. And I would like to know if it was inserted or not, of course. I assume the way to do that is to use `mysql_insert_id()`. It returns 0 if no insertions happen and 1 if insertions happen. Looking more details [here]( https://dev.mysql.com/doc/refman/5.7/en/mysql-insert-id.html) > If an INSERT ... SELECT statement is executed, and **NO** automatically > generated value is successfully inserted, mysql_insert_id() **RETURNS** > the ID of the last inserted row. What does it return if no auto-generated ID was successfully inserted? Is this a doc typo? So far I did testing in C and `mysql_insert_id()` returns always 0 if insertion did not happen even if the last insertion succeeded and `mysql_insert_id()` returned non-zero result. A paragraphs in the same manual, mentioned above, confirms this behavior by saying: > mysql_insert_id() returns 0 if the previous statement does not use an AUTO_INCREMENT value. .... > > The value of mysql_insert_id() is affected only by statements issued within the current client connection. It is not affected by statements issued by other clients. > > The LAST_INSERT_ID() SQL function will contain the value of the first automatically generated value that was successfully inserted. LAST_INSERT_ID() is not reset between statements because the value of that function is maintained in the server. .... And that feels kind of logical otherwise `INSERT...SELECT` would be useless in many cases, if you cannot know within the code if your insertion worked or not. But it totally contradicts to the statement above. Did anyone have experience with this? >From MariaDB manual, also suggests that the value should be zero in case of insertion did not happen: > The mysql_insert_id() function returns the ID generated by a query on > a table with a column having the AUTO_INCREMENT attribute or the value > for the last usage of LAST_INSERT_ID(expr). If the last query wasn't > an INSERT or UPDATE statement or if the modified table does not have a > column with the AUTO_INCREMENT attribute and LAST_INSERT_ID was not > used, this function will return zero. Does `mysql_insert_id()` of MariaDB returns 0 for `INSERT...SELECT` if an insertion did not happen, or it might return some other non-zero value? Do you think it is a typo at MySQL documentation? Best, Yuki

[Maria-discuss] Replication set up to ignore Delete statements
by Furlong, John 25 Jan '18

25 Jan '18

I am new to MariaDB and am wondering if it's possible to set up replication to only replicate INSERTS & UPDATES? Can Deletes be ignored? The purpose is to keep the primary DB small and the secondary DB would be a data warehouse. Does --binlog-format=STATEMENT mean all writes? I've been reading the documention but haven't been able to find a definitive answer. If Delete statements are executed by a different user is it possible to ignore them that way such as through the CURRENT_USER()<https://mariadb.com/kb/en/current_user/> function? Thanks. John

[Maria-discuss] ALTER TABLE ENIGNE=InnoDB performance
by Conor Murphy 25 Jan '18

25 Jan '18

Hi, We're looking at changing an existing database from MyISAM to InnoDB. The existing system is using MariaDB 5.5.56 on RHEL 7.4 The plan is to - create a replication slave on the same host - use ALTER TABLE .. ENGINE=InnoDB on the slave, with 4 ALTERs running concurrently - replace the master with the "coverted" slave Doing this with a small database (~ 3.5GB) works okay with the largest table taking ~ 7 minutes to convert. However, while trying to figure out how to replicate from the new master, we found that we need "FLUSH TABLES .. FOR EXPORT" which isn't available in MariaDB 5.5. So we updated to MariaDB 10.2.12 and started again. Now when we run the "ALTER TABLE .. ENIGNE=InnoDB", it takes hours from the ALTERs to complete and we're getting the following log entries 2018-01-09 12:36:03 140132036818688 [ERROR] InnoDB: Cannot save table statistics for table `statsdb`.`#sql-6d1a_12#P#P20160101` /* Partition `P20160101` */: Lock wait timeout 2018-01-09 12:36:54 140132036515584 [ERROR] InnoDB: Cannot save table statistics for table `statsdb`.`#sql-6d1a_13#P#P20160101` /* Partition `P20160101` */: Lock wait timeout 2018-01-09 12:37:45 140132036818688 [ERROR] InnoDB: Cannot save table statistics for table `statsdb`.`#sql-6d1a_12#P#P20160601` /* Partition `P20160601` */: Lock wait timeout 2018-01-09 12:38:36 140132036818688 [ERROR] InnoDB: Cannot save table statistics for table `statsdb`.`#sql-6d1a_12#P#P20160701` /* Partition `P20160701` */: Lock wait timeout 2018-01-09 12:39:27 140132037728000 [ERROR] InnoDB: Cannot save table statistics for table `statsdb`.`#sql-6d1a_11#P#P20160701` /* Partition `P20160701` */: Lock wait timeout ...

[Maria-discuss] MariaDB 10.3.4 consumes extremely much CPU on Windows.
by Peter Laursen 21 Jan '18

21 Jan '18

On a 4-core (4 physical, 8 logical cores), 3.5 Ghz box, MariaDB 10.3.4 consumes typically 35-40% of available CPU even when completely idle according to Task Manager. Please see image. I cannot tell if previous 10.3 versions also did, as I don't have 10.3 running constantly in the backgorund. I just observed this now. This does not happen with MariaDB 10.1, MariaDB 10.2, MySQL 5.6, MySQL 5.7 and MySQL 8.0 (all those I have starting with Windows on this box), where the CPU-load is neglible unless the server is "doing real work". As a result, the CPU clock frequency is always highest possible 3.5 Ghz (this CPU model is a 4th generation Intel with the option to scale down CPU frequency to around 40-50% of max. when there is no need for more) when MariaDB 10.3.4 is running. -- Peter -- Webyog

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
