[Maria-discuss] [question] password input length
by Michal Schorm 16 May '18

16 May '18

Hello everyone, 1) I found out, that passwords longer than 79 characters aren't accepted via password prompt. Is that expected? Morie info and reproducer in RH bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1566179 -- 2) Another password length cap at 213 characters can be found when using sha256_password authentification plugin. Is that expected too? Morie info and reproducer in RH bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1566219 -- 3) Different theme: why aren't tests for mariadb-connector-odbc, that can be found on GitHub, packged to the source tarball ? -- Michal Schorm Associate Software Engineer Core Services - Databases Team Red Hat

[Maria-discuss] MDEV-15765 BETWEEN not working in certain cases
by Michael Caplan 08 Apr '18

08 Apr '18

Hello, I've just stalled a rollout to production of 10.2.14 because of this what I think is rather huge SQL break (https://jira.mariadb.org/browse/MDEV-15765) Anyone else holding 10.2.14 from production? Anyone running 10.2.14 in production? Trying to get some additional perspective on this issue. Thanks, Mike

[Maria-discuss] Replication New to Old
by Michael Caplan 08 Apr '18

08 Apr '18

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
