rpmdiff reports changed size but unchanged checksum

[pavlix]

Maybe I just misunderstood something but how can rpmdiff report difference in size and not difference in checksum for so many files?

$ rpmdiff -i T /var/tmp/build-root/standard-x86_64/home/abuild/rpmbuild/RPMS/x86_64/coreutils-8.25-0.x86_64.rpm binaries/coreutils-8.25-4.1.x86_64.rpm 
removed     PROVIDES coreutils(x86-64) = 8.25-0
added       PROVIDES coreutils(x86-64) = 8.25-4.1

I don't know offhand, nor could I manage to reproduce in a quick test. If you have the rpms for which this happens somewhere available for download, I can have a closer look.

[dirkmueller]

So these are directories, right? I've seen that on some.filesystems already as they report not the normal blocksize for disk usage

[pavlix]

@scop Given the information from @dirkmueller I guess I don't need to upload them...

@dirkmueller Does it mean the RPMs store the size of directories even though it's of zero significance? Should that be changed or should rpmdiff just ignore it?

[pavlix]

Another question is whether it shoudln't at least mark directories so that you know what types of objects it compares.
