Comment(by ddrake):
For testing, naturally you need to start by applying
attachment:trac_329_sage_scripts.patch.
To create a .spkg with checksum information: take any existing .spkg file,
and use the sage-add-integrity-check-to-spkg script:
{{{
sage-add-integrity-check-to-spkg foo.spkg
}}}
You needn't run that in a "Sage shell"; it only uses ordinary system-wide
utilities. That will add the checksum information into the .spkg file.
To test that the checksum information works, try installing
http://sage.math.washington.edu/home/drake/trac329/pexpect-99.0.spkg which
has correct checksum information. Then try
http://sage.math.washington.edu/home/drake/trac329/pexpect-100.0.spkg
which doesn't. (You'll see that I just put the word "bad" into the correct
checksum.)
Hopefully the suspicious version numbers prevent anyone from actually
using those .spkg files (although they install a perfectly working version
of pexpect).
The installation should work for the "99" spkg and fail for "100" spkg.
Look for "Verifying integrity of ...pexpect-99.0.spkg..." lines.
