Package: debdelta
Version: 0.21
Severity: wishlist
Hello,
I tried using debdelta and think it is a very good idea. However,
besides many errors I got, I was surprised (negatively) by the size of
the deltas.
For example, the delta between kdelibs4c2a on i386, versions
3.5.7.dfsg.1-1 and 3.5.7.dfsg.1-2 which is 3 MB large, while the
package itself is 12 MB. I think this is quite much.
So I tried some possibilities of diffing (diffing the tar of
data.tar.gz, diffing files separately) and found out these come out
more or less the same. Also, I tried other diffing programs (xdelta,
bsdiff[1], edelta[1]) and bsdiff was a clear winner among those. In
the kdelibs4c2a example, the diff was only 600k.
What do you think about this? Would it be possible to change the
diffing algorithm?
Regards
Jiri Palecek
