Package: libmariadb-dev
Version: 1:10.5.12-1+b1
Severity: normal
X-Debbugs-Cc: akira.m...@gmail.com

Dear Maintainer,

Since Debian 11 or Ubuntu 21.10, the command 'mariadb_config --plugin' returns '/usr/lib/arm-linux-gnueabihf/libmariadb3/plugin' which doesn't work. MariaDB server doesn't load the plugins installed in the directory. I
think it should be '/usr/lib/mysql/plugin/'.
The same issue occurs on x86_64 systems too.

It returned the correct directory on Debian 10 or Ubuntu 20.04 as far as I tried.

Thanks, Akira.

Hi Akira!

With Debian 10, the path is /usr/lib/x86_64-linux-gnu/mariadb19/plugin,
see bellow:
| ~$ podman run -it debian:10 bash -c "apt-get update && apt-get install -y libmariadb-dev && mariadb_config --plugin"
| ...
| /usr/lib/x86_64-linux-gnu/mariadb19/plugin
|
| ~$ podman run -it debian:11 bash -c "apt-get update && apt-get install -y libmariadb-dev && mariadb_config --plugin"
| ...
| /usr/lib/x86_64-linux-gnu/libmariadb3/plugin

You may be confusing with the mysql_config script? See also
https://jira.mariadb.org/browse/MDEV-13836.

The man page is quite clear about this behavior:
| NAME
| mysql_config - get compile options for compiling clients
|
| • --plugindir
|
| The default plugin directory path name, defined when configuring MariaDB.

Also, please note that /usr/lib/mysql/plugin/ does not exist if you only
install libmariadb-dev.

| ~$ podman run -it debian:11 bash -c "apt-get update && apt-get install -y libmariadb-dev && ls /usr/lib/mysql/plugin/"
| ...
| ls: cannot access '/usr/lib/mysql/plugin/': No such file or directory

If you think this is still problematic, please report it upstream
(jira.mariadb.org).

Thanks!

Hi!

Latest version of MariaDB in Debian unstable/testing/Bookworm is
10.11.2. You might want to consider testing it.

If you want to contribute in the open source way to fix this or any
other issue, see
https://salsa.debian.org/mariadb-team/mariadb-server/-/wikis/Contributing-to-MariaDB-packaging-in-Debian
on how to submit a Merge Request!

If you have time to help, please consider these (in order of importance):

1. Review current open MRs at
https://salsa.debian.org/mariadb-team/mariadb-server/-/merge_requests

2. Review items highlighted by Debian QA systems (Lintian, builds etc)
and submit a fix to improve the quality:
https://tracker.debian.org/pkg/mariadb

3. Review what testing we have at
https://salsa.debian.org/mariadb-team/mariadb-server/-/pipelines and
think about potential gaps - CI is very important as it is the only
way we can prevent regressions in a scalable way

4. Review/follow-up on existing bugs that currently need more
information: https://bugs.debian.org/cgi-bin/pkgreport.cgi?repeatmerged=no&src=mariadb&src=mariadb-10.6&src=mariadb-10.5&src=mariadb-10.3&src=mariadb-10.1

MariaDB and C++ skills are useful, but not required. For example
reviewing the NEWS for 10.11 requires no coding skills:
https://salsa.debian.org/mariadb-team/mariadb-server/-/merge_requests/37

My request for help from debian-devel in
https://lists.debian.org/debian-devel/2023/02/msg00272.html did not
get many responses, so the future of this package depends on how
active the users and people who previously reported bugs are in
participating in the maintenance of the package.
