Description Kamil Páral 2009-10-12 17:07:33 UTC 
Description of problem:
When packages are not the same, rpmdiff prints differences, every difference on a single line. No line is empty.

When packages are the same (at least from rpmdiff's perspective), rpmdiff prints single empty line.

That's is not correct, in my opinion. It should not print anything in the second case. When there is some line printed, I expect something to be there.

As a matter of fact, my script, which I am building on top of rpmdiff, is crashing exactly because of this issue.

Version-Release number of selected component (if applicable):
rpmlint-0.91-1.fc12.noarch

How reproducible:
always

Steps to Reproduce:
1. $ rpmdiff package.rpm package.rpm
Comment 1 Ville Skyttä 2009-10-13 19:04:01 UTC 
Fixed upstream, but I suggest making your script more robust against unexpected input.  http://rpmlint.zarb.org/cgi-bin/trac.cgi/changeset/1664
