Hi Sergei! I was wondering the same! Justin's explanation is probably correct, but I think that various discussions in this list proven that a part of the community badly wants this feature. I wrote a unit tester in SQL some time ago (I know it may sound weird, but I needed it to test several things, from procedures to query time, and even metrics). It was insanely hard. I mean - I think I can write a unit tester in JavaScript or PHP or even BASH in a few hours, with all the features I want. But SQL is full of traps, so it took weeks (of course it was not my only task). Some of the features that have been discussed in this list could have been implemented as stored procedures. For example, extensions to KILL. It may not be the perfect solution but, well, it is not reasonable to expect that you implement every single need/idea I have during my work. If I could write general purpose stored procedures in any decent language, I would do it, and then would push them to GitHub. It seems that some people agree on this but... still nothing happens. Even PL/SQL parser seems to have higher priority than external languages! :( Is there anything we can do to convince the team?

[Maria-discuss] Community Involvement - GSoC Mentor Summit impressions
by Vicențiu Ciorbaru 07 Nov '16

07 Nov '16

Hi everyone! Since MariaDB has completed another Google Summer of Code program this year, with some great projects as well, the MariaDB Foundation was able to send 2 mentors to the summit in California this year. I was one of the people that had the privilege to go. There were a lot of talks there about community involvement and how to encourage people to contribute. I've picked the ideas that I've found to be most interesting and useful and have blogged [1] about them. I intend to try and apply some of them if possible. Since this is a community matter (albeit more GSoC related), it makes sense to ask for feedback from the community. I think some of the ideas are at least partly implemented but we can always do better. If you're interested, lets have a discussion on this.

[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] MYSQL_OPT_CONNECT_TIMEOUT default?
by Peter Laursen 03 Nov '16

03 Nov '16

MySQL docs page http://dev.mysql.com/doc/refman/5.7/en/mysql-options.html *MYSQL_OPT_CONNECT_TIMEOUT (argument type: unsigned int *)* *The connect timeout in seconds.* However I don't find it documented anywhere what the default (client-initiated) connect_timeout will become if not specified in mysql_options(). Or will the client never initiate a timeout in connection phase in such case? We are usng MariaDB C-conn 2.31 so the question here on this list is specifically for MariaDB connector. I didn't find it documented here either. But both MySql and MariaDB have probably inherited this from the old LGPL 3.x connector so this are probably the same in both. Asked a docs request here as well: http://bugs.mysql.com/bug.php?id=83600 --- Peter

[Maria-discuss] upgrading galera 10.0 -> 10.1 without writes downtime
by Federico Razzoli 02 Nov '16

02 Nov '16

Hello list I have to upgrade a cluster and I hoped I can do it safely without a downtime. In my understanding though it is not possible. In my specific case, the cluster is 10.0 and must be upgraded to 10.1. There is a "master" node. Steps are: 1. I upgrade all "slave" nodes 2. I change the "master" 3. I upgrade the old master The problem is that, between 2 and 3, old master is 10.0, and it replicates from 10.1. This is not supported, based on this page: https://mariadb.com/kb/en/mariadb/upgrading-mariadb-upgrading-from-mariadb-… "to prevent 10.1 propagating to 10.0, which is not supported" So my question is, is there a way to upgrade this cluster without writes downtime? Regards, Federico
