Are you literally "adding to each .spkg file". If so,
make sure this is completely automatic. I.e., whenever anybody does
sage -pkg directory-version
the md5 file is created inside the resulting spkg. What are you
going to create the md5 hash of, by the way, given that the spkg
doesn't exist when you create the md5 hash to add to the spkg?
The alternative is that we have to have separate files
directory-version.spkg
and
directory-version.spkg.md5
and then whenever anybody ever wants to trade spkgs, they have
to copy around, get, etc. 2 separate files. That would be painful
in practice.
Just out of curiosity, shouldn't tar report if the file it is
unpacking is somehow corrupt? Why do we need md5 hashes at all
if the whole point is to determine whether or not a download of
a .tar.bz2 file (an spkg) was corrupted or not? Should we be
able to get that information from tar during the extract process,
or at least change how we make the tarball so that information
is available.
I really don't want to have to keep track of twice as many files
if it isn't absolutely necessary.
