Is any sense to call preprocessResults on empty set?

Thanks for reporting and investigating.

Good question, it probably does not make much sense. Looking through other special pages using it: https://codesearch.wmcloud.org/search/?q=function+preprocessResults it looks like most of them start with if ( !$res->numRows() ) { return; } or something like that.

However, I don't really want to review 50+ special pages to make sure it would be a safe change, and it could also affect other code by third-party users that we don't have indexed in Codesearch, so I will just add a similar check to the DiscussionTools code for now.

The problem still occurs in 1.42. I think need to backport the changes.

Updating can be tricky sometimes, we don't test current releases with 1.42 (or any previous MediaWiki releases). I guess it won't hurt to backport it.
