The postinst of Mroong install is, and the postrm uninstalls it
correctly. There is however no code that would on a
postinst/preinst/upgrade scenario reinstall the plugin if the path has
changed (eg. as it does on in MariaDB 10.3 when the soname path
updates from libmariadb18 to libmaridb19).


*********************************************************************************
mariadb-10.3/debian$ cat mariadb-plugin-mroonga.postinst
#!/bin/sh

set -e

# Install Mroonga
# No user or password parameter is required with new MariaDB that
# has unix socket authentication support by default.
mysql < /usr/share/mysql/mroonga/install.sql || true
# Always exit with success instead of leaving dpkg in a broken state

Just out of curiosity, what is the best way to detect
soname path updates in maintainer script?
If there is a similar package which treats this kind of issue, I want to know.

Hello!

I don't know, unfortunately.

You can try if you find any examples via
https://codesearch.debian.net/ or discuss it on debian-devel@ mailing
list or on IRC. If your questions are MariaDB-specific you can ask
help on the MariaDB developers mailing list or Zulip chat.

Current status:

- mariadb-plugin-mroonga.postinst does the install
- mariadb-plugin-mroonga.prerm does the uninstalls
- both seem to run on upgrades


The current problem is that on upgrades mariadb-plugin-mroonga.prerm
runs at a time when the mysqld is not running, and thus fails. Since
there is no real need to unstall on an upgrade this does not matter,
but looks ugly:
