The from_md5 and to_md5 fields were a nice extra safety, which would avoid trying to apply deltas on corrupted package files. However, they are not strictly necessary, since xdelta should be able to detect that on its own. The main problem is that it is impossible to compute these informations from the delta only. So repo-add would not be able to compute the delta entry based on just the delta file. Signed-off-by: Xavier Chantry <shiningxc@gmail.com> Signed-off-by: Dan McGee <dan@archlinux.org>
