unknown variable 'innodb_support_xa=1'

would you funny guys consider things like deperectaion warnings in previous releases

A deprecation warning was added in the MariaDB Server 10.2.2, well before it was Generally Available. That said, maybe there is a nontrivial amount of users who skipped the 10.2 release and upgraded straight from 10.1 to 10.3.

come on and show me!

Here, warnings as added in 10.2.2:

https://github.com/MariaDB/server/blob/mariadb-10.2.2/storage/innobase/handl...

But you're still right, you did not see them.

The warning (if I read the sources correctly), was issued when innodb_support_xa was changed run-time or when MariaDB was started with innodb_support_xa=0. For the initial innodb_support_xa=1 there was no warning (because 1 was the default value for innodb_support_xa)

smart admins prefer fixed configurations in case some sloppy commit or minor update changes the default well, and that's a problem given that you refuse to start the server just because you don't understand a random config option and so no matter how much tests one is running the matrix of available and potentially silent disappearing options means "good luck when you update" not only when you update, also when because of a changed or broken cmake optionsthe binary of the old version supported something which the new don't and the attitude of MariaDB adding new features to existing GA releases or randomly break compile options between minor versions make that a very uncomfortable world to live for admins just don't refuse to start the service becaus eof such things it's as simple as compile a list of all known and previous known options and isssue only a warning instead of a fatal error if they are not supported with the current build no matter why innodb_support_xa=1 == deperaction warning innodb_support_xb=1 == you recently added soemthing with a typo
