There's no need for Debian to set config items to their
default. Left commented user, datadir and tmpdir as
these may want to be changed. lc-messages and skip-external-locks
are so infrequently set even listing them looks overly verbose.
socket left uncommented in [client-server] as various client
implementations may have different defaults compiled in.
- Include a link to the relevant KB article for more info
- Use spaced around the equal sign for better readability and so that
the examples are more aligned with the general style in the KB
- Load plugins with just the base name, the .so is optional and excess
- Remove unnecessary unused files
- Remove duplicate encryption configuration sample from sources and
re-use the identical file in RPM directory instead
- Clean away harmful "default-character-set = utf8mb4" from client config
as it is unnecassary (server enforces utf8mb4 anyway by default) and
could cause issues with mysqlbinlog and other tools (MDEV-22981).
- Update S3 plugin description to be long enough
- Remove trailing whitespace from support-files and Debian packaging.
- Clean away fixed Lintian issues
- Clean away temporary Salsa-CI fixes now that 10.5.4 is out and is fixed
- Apply wrap-and-sort -a -v
- Recommend max_allowed_packet=1G which is the same as the default client
value.
- Remove thread_concurrency removed in 10.5.
- Remove query cache, not recommended practice anymore.
- Remove binlog_*, should not recommend those too easily but rather require
the database administrator to read up on those themselves.
- Remove chroot setting, not relevant in modern container era.
- Show explicitly innodb_buffer_pool_size example as the most likely thing
a database administrator should change.
- Don't recommend rate limiting in slow log, logging once in a 1000
would not be optimal for the basic case, hence bad example.
- Install the example configs in /usr/share/mysql.
- Use correct path /run/ instead of /var/run/.
Split the big my.cnf into multiple smaller files with the same filenames
and contents as official Debian/Ubuntu packaging has.
The config contents stays the same apart from following additions
which the original MariaDB upstream configs had and probably needs
to be kept:
- lc-messages=en_US and skip-external-locking in server config
Configs the original MariaDB upstream had that are seemingly
unnecessary and thus removed:
- port=3306 removed from the client config
- log_warnings=2 removed from server config
Also adopt update-alternatives system using
mysql-common/configure-symlinks. This way it is aligned with
downstream Debian/Ubuntu packaging.
