Comment:

 trac1912 is ready for review.

 The change is small and should be straightforward.

 Proposed changelog entry:

 {{{
 443.?   [bug]           jinmei
         libdatasrc: fixed ZoneFinder for database-based data sources so
         that it handles type DS query correctly, i.e., treating it as
         authoritative data even on a delegation point.
         (Trac #1912, git TBD)
 }}}
