unknown variable 'innodb_support_xa=1' would you funny guys consider things like deperectaion warnings in previous releases or at least offer an option to change all these fucking "i don't know a option because it was removed or you did not compile something in and hence i refuse to start the server" to warnings?

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.

That we do if you specify the loose_ prefix to the options. With best regards, Marko Mäkelä Lead Developer InnoDB MariaDB Corporation

The way i understand Marko's sentence the deprecation warning was in 10.2 and only 10.2, since you skipped over directly to 10.3 it's to late for the warning the variable is goen

You are right that a warning should be issued for deprecated variables if any value was specified in the configuration file or by a command line option. Unfortunately, I am not aware how a storage engine could distinguish the compile-time default value from a user-specified identical value. That is why InnoDB did not issue the deprecation warning for you. Maybe you can submit a fix that would address this deficiency?

sadly i am not a C/C++ delevoper but i would expect it to be as simple as two simple *global* lists $known_options = ['innodb_support_xa', 'performance-schema=0', ...] $deprecated_options ['innodb_support_xa', ....] -DPLUGIN_PARTITION=NO, -DPLUGIN_PERFSCHEMA=NO where broken in multiple point releases the past years and everytime one decided "well, then disable that build option and use the config option to disable it" leaded later in "oh fuck, now the the build was fixed it no longer starts because of the now unknown option" a simple lookup in "known_options" and react with a generic warning that this option is not supported in the current build instead refuse to start and refuse only when a total unknownm option appears would have safed a lot of headache

I thought that we could've changed the default to, say, 2. Then both 1 and 0 would mean that the value was specificed explicitly. Or something like that. Regards, Sergei VP of MariaDB Server Engineering and security@mariadb.org

"-DPLUGIN_PERFSCHEMA=NO" is the same as "performance-schema=0" is doing the same while "performance-schema=0" on a binary with the built with the first one prevents mysqld from start when i *explicit disable* some bloatware crap it's missing exitence is not a hard error that is idiotic, the same for partitioning and so on any fucking option from the documentation must not trigger hard errors when it exists in a config file, no matter what - period

for a service which simply refuses to restart because of some unkown option as result of a different build option it's *mandatory* not just nice, especially when build-options are known to randomly break between bugfix releases

Note, that his use case is an option that was explicitly set to its default value in my.cnf, and in 10.3 was removed in the server (so the default value became hard-coded behavior and not configurable anymore). That is, the option had no consequences, if it had, if it was set to a non-default value, he'd get a warning in 10.2. And removal of an option in 10.3 did not change InnoDB behavior for him, the only effect was that the option stopped being recognized by the server and the server refused to start.

Hi Sergei, Yes i got this, but still, i largely prefer mysql/maria to not start so i know something is wrong, to bloating to code for handling potentially not built / removed options. In this case maybe to deprecated should have been handled better yes but hey, that doesn't justify this tone. I have lost many more hour with lost sleep and data corruption with maria recently but i did not insult anyone ... Nor when i hit my head trying to counter some performance degradation since the jump to maria in some inefficient query parsing. In any case that's your software so

Marko, I believe we can expect these kinds of deprecation with people upgrading from Debian Stretch to Buster.

Yes, it is possible. That Debian bug was special in that the options used to be part of the Debian-shipped configuration file. The user who reported the bug had edited the configuration file that was shipped with the older version, so the Debian upgrade would notice a conflict and ask the user what to do. Apparently the user chose to preserve the original configuration (with the modifications), and as a result, MariaDB Server 10.3 would fail to start up. I addressed this by adding back these as string parameters, and issuing a deprecation warning whenever any value is specified. Marko -- Marko Mäkelä, Lead Developer InnoDB MariaDB Corporation

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). Regards, Sergei VP of MariaDB Server Engineering and security@mariadb.org

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
