When testing changes for bug 636798, I noticed that binarytree.populate() always re-writes $PKGDIR/Packages if any MD5 digests are missing. The problem arises due to this code, where MD5 is part of the self._pkgindex_keys set: > if not self._pkgindex_keys.difference(d): > match = d > break The problem is easily corrected by running `emaint --fix binhost` to generate the missing MD5 digests, but the code should really be fixed to avoid the unnecessary re-writes.
