Request for help to make mariadb-10.3 in Debian reproducible

[Otto Kekäläinen]

Hello!

The MariaDB server itself and most of it's additional components are
already reproducible and we are very close to the whole source package
build reproducibly.

For the last remaining issues I now need to request help.

Latest results from
https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/mariadb-10.3.html
show issues with:
- mariadb-plugin-mroonga
- mariadb-plugin-rocksdb
- mariadb-plugin-tokudb

For RocksDB there is a potential fix
(https://github.com/facebook/rocksdb/issues/6276, WIP at
https://salsa.debian.org/mariadb-team/mariadb-10.3/commits/bugfix/reproducibility).

For Mroonga I nor the upstream developers have no clue yet of the root cause:
https://github.com/mroonga/mroonga/issues/298

TokuDB upstream is almost dead, so there hasn't been any discussions
with them and the plugin fails in many ways in diffoscope, so I am
also considering to drop the whole plugin from some future release of
mariadb-10.3 or mariadb-10.4. It should be fixed however is somebody
figures out what how to do it.

I would be very glad if somebody wants to help out. Either by advice
or other input to the issues or maybe even with a patch, since
presenting a proven real solution is always the best argument :)

I promise to quickly review and merge if somebody sends in patches at
https://salsa.debian.org/mariadb-team/mariadb-10.3/

PS. If you can help, and attend FOSDEM, I promise to return the favor as beer :)

PPS. Thanks for help with galera-3 in September, both galera-3 and
galera-4 has been building reproducible ever since :)
