I've removed the comprehensive approach for HelpCommandDistTest to be working for the product. It'd bring a lot of maintenance difficulties. You can check out what'd be necessary to make it work here: mabartos@0246380

[vmuzikar]

I think we should have some test coverage to check GELF is not present in the help. But I agree adding more approved help txts is a bit cumbersome.

Maybe we could create some CheckGelfRemoved test that would just assert the string gelf is not present in help?

[mabartos]

@vmuzikar That should be sufficient. I manually tested for GELF enabled/disabled and it works as expected.

Is it ok for you?

We'll also need to update the docs to exclude GELF on -Dproduct.

[ahus1]

@mabartos - the logging guide mentions GELF explicitly, so I assume it needs to be changed as well (either in this PR, or another PR).

[mabartos]

@ahus1 Yes, I'm on it.

[mabartos]

After a discussion with @pedroigor, the property persisting during the build time is not a blocker for this PR.

Documentation stuff works as expected; I've tried it with product doc.

@vmuzikar Could you please check it? (Sorry, I've already squashed all commits, but no big changes were provided since the last time)

[pedroigor]

@mabartos Sure. We can do it as a follow-up.

[vmuzikar]

@mabartos Thanks for the update! Can you please create an issue for the follow-up?

[mabartos]

Created follow-up general task related to the static initialization : #22799
