That's simply searching if this attribute (the one with keyname) exists 
for the solvable in question.  If it returns here it means for that 
solvable this attribute doesn't exist.

You should look at the metadata (use dumpsolv on the solv file in 
/var/cache/zypp/solv/$REPO/solv for the repository in question).  For 
diskusage it needs to have the "solvable:diskusage" attributes (that's per 
directory, if you need that per mount-point you need to call some helper 
functions, e.g. pool_calc_duchanges) or simply "solvable:installsize" 
(that's the overall installed size of the package), for that no 
post-processing is required.


Ciao,
Michael.
