There are 2 questions here: * Should we add support for MariaDB? And if so which versions. Just found that there’s an official docker image for it so it should be relatively easy to support MariaDB in our docker-based testing framework: https://hub.docker.com/_/mariadb/ (TestContainers also has a wrapper now for MariaDB: https://github.com/testcontainers/testcontainers-java/tree/master/modules/ma...). Note that the MariaDB versions don’t match the MySQL versions.
FTR, I’ve tried adding support for MariaDB and it’s currently not working, because of https://github.com/testcontainers/testcontainers-java/issues/949. But we could provide a PR to them with not so big efforts or using a GenericContainer (less nice).
Maybe I'm misunderstanding, but it looks like we're mixing XWiki's support of the MariaDB database itself with XWiki's test infrastructure's capability to support a MariaDB database container, which looks a bit off-topic to me. I get that we need it integrated in our tests to detect anomalies, but I don't really see it as an eliminatory criterion. Thanks, Eduard
Thanks -Vincent
* Should we drop support for MySQL?
Thanks -Vincent

Hello,
We are in a weird situation where we don't say we support MariaDB but "the latest MySQL version of stable Debian repository", which is currently... MariaDB [1]
So we need to update our strategy about this fact. I am currently setting up a server with debian 9 (stable) and I don't know if I should install MySQL from the Oracle repository our continue with the standard debian package (MariaDB).
On my side, I am not against aligning ourself to debian. Basically, all users installing XWiki with our Debian packages are using MariaDB for a year now [2], and we never encounter any problem so far.
Thanks,

Indeed mysql-server package (version 5.5.9999) leads to mariadb-server-10.1 in current stretch repository.
What is surprising is that this is not the case for sid which is more or less supposed to be the future. It's also not the case in Ubuntu which is doing the same thing as sid. On Mon, Nov 12, 2018 at 6:22 PM Eduard Moraru <enygma2002@gmail.com> wrote:
I am not up to date on the topic, but I would like to add the fact
that
Debian 9 ("stretch") has actually dropped MySQL and moved officially to MariaDB, forcefully migrating existing MySQL installed versions to MariaDB.
https://www.debian.org/releases/stable/amd64/release-notes/ch-whats-new.en.h...
The default mysql-server package now redirects to MariaDB instead.
If we are going to follow Debian's lead, we might want to at least
consider
this move.
Thanks, Eduard

FYI, I’ve now updated the page at
https://dev.xwiki.org/xwiki/bin/view/Community/DatabaseSupportStrategy
(but I can update/revert if need be).
