[Maria-discuss] Drop user not replicating in 10.2.16/17 galera cluster with NO_AUTO_CREATE_USER in mysql_mode
by Vincent Hoffman-Kazlauskas 15 Aug '18

15 Aug '18

Hi all, not sure if this is expected or not. I am running a test cluster in preparation for upgrading from 10.0 to 10.2 and noticed that DROP user commands were not being propagated to other members of the galera cluster. The only user management changes of note I know of was the addition of NO_AUTO_CREATE_USER to sql_mode and indeed removing that from sql_mode appears to have resolved it. My question is, is that expected behavior and if so whats the modern way of removing mysql users from a mariadb galera cluster. If not is it worthy of a bug report? Thanks, Vince

[Maria-discuss] New testsuite option
by Michal Schorm 13 Aug '18

13 Aug '18

Hello, I take care of MariaDB in Fedora & RHEL. We run the testsuite there. Every time, in every build, with --big-test. Time to time it happens that some of the tests fail. For example during a rebuild. For such cases, I'd use a way to tell MTR what is a unstable test treshold, which means "how many tests can fail to still count the testsuite run as a success". Most likely, I'd use it with value from 1-5. Any larger group of failing tests needs to get my attention. Anyway I still could spare myself of the unstable tests. -- (Asking before filling any JIRA feature request) 1) Is there already some way to do that? 2) Do you find such feature usefull? 3) Any ideas how to call such option? --max-test-fail is already used -- Michal Schorm Associate Software Engineer Core Services - Databases Team Red Hat

[Maria-discuss] Copying database files
by Ling, Andy 13 Aug '18

I'm using MariaDB 10.2.13 on Windows 7. All tables are using the Aria engine. I am trying to initialise a slave database by copying the files between PCs, but when I try and use the copied files I get the error Table is from another system and must be zerofilled or repaired to be usable on this system Repairing the tables fixes this, but I'd rather not have to so that. I have tried various things suggested to stop this, but nothing seems to help. On the source server I have run aria_chk -zerofill on all the tables. Before copying the tables I run FLUSH TABLES <table list> FOR EXPORT, but I still get the error. What do I need to do to make this work? Thanks for any help.

[Maria-discuss] MariaDB Zulip
by Ian Gilfillan 04 Aug '18

04 Aug '18

A reminder that MariaDB is trialling Zulip, which provides both Slack-like and IRC-like functionality. Zulip is an open-source tool that can also provide native integrations with various other tools, including GitHub. At the moment the MariaDB Foundation has been using it internally for most communications, and there's not been much public activity, but we'd like to invite developers and others interested in MariaDB to come try it out as well. So far the responses from those using it have been positive. Visit it at https://mariadb.zulipchat.com.
