Hmmz, i didn't forgot to attach it so it got stripped somewhere
in the way, anyway here it is:
http://vdev.datamax.bg/tmp/portsaddsha256.sh
--- portsaddsha256.sh begins here ---
#!/bin/sh -e
portsdir=${1:-/usr/ports}
distfilesdir=${2:-$portsdir/distfiles}
get_distinfos()
{
find $1 -maxdepth 3 -mindepth 3 -name distinfo
}
extract_archives()
{
# get all archives that have MD5 sum
# ones that do not have MD5 sum do not deserve SHA256 sum
for archive in `cat $1 |sed -nE 's/^MD5 \(([^)]+)\) = [0-9a-f]{32}$/\1/p'` ; do
# output only archives that do not already have SHA256 sum
if [ -z "`grep '^SHA256 ($archive)' $1`" ] ; then
echo $archive
fi
done
}
cd $distfilesdir
for distinfo in `get_distinfos $portsdir`; do
for archive in `extract_archives $distinfo` ; do
if [ -r $distfilesdir/$archive ] ; then
sha256 $archive >> $distinfo
fi
done
done
# EOF
--- portsaddsha256.sh ends here ---
See Kris's statement about `make makesum', that's why I choose
`sha256 foo.tar.gz >> distinfo'
>>It *SURELY* does not do anything else than adding the sha256 sum<<

My thought is that this (or similar) script be run on a machine where
all the distfiles are available, mine is about 5% of all :)
Anyway if it does not happen in a week or so I will send-pr it.
