Hi Jah,

I beileve I've fixed this now. Could you please try again?

Thanks,
Hi Patrick,

I believe you have, nice work!  I've tested it and get no errors and
print_debug() is working again.

Would you please apply the attached patch to http.lua, because I messed-up.
Previously there was this in a loop to read from a buffer:

    status, line = buffer()
    if (not status or line == "") then break end

and I sent a patch to make it:

    line = buffer()
    if not line then break end

which should have been:

    line = buffer()
    if (not line or line == "") then break end

otherwise an empty string doesn't get detected as a break between an
http header and the body and it reads the entire response into the
header table.  Whoops.

Cheers,

jah
