hi. i browse into alpm code, and just find that repo-add adds lines like that to a deltas file $fromver $tover $deltasize $deltafile $deltamd5 but _alpm_delta_parse (in delta.c) which is used in be_files.c, expect the same line to be $oldfile $oldmd5 $newfile $newmd5 $deltafile $deltamd5 $deltasize is it because this delta stuff is not finished yet ? or i am simply completly wrong ?? by the way, i am trying to create a bsd db4 back-end for alpm. i have written convert.c, rewritten repo.add.py.in, pmdb.py. i have to rewrite be_files.c yet, the big part. what do you, the dev, think of that ? i know that almost every one was against such a thing some time ago, and might still do. i do it mostly as an exercise but it would be nice if it is used. cheers
