unversioned upstream source

[Patrice Dumas]

Hello,

I am seeking advice, or even better guidelines on the issue of unversionned 
upstream source.

There is a dispute which may be seen here:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=197488

The upstream tarball is unversioned, I would like to add the timestamp to
the tarball name to avoid having different tarballs with the same name, in 
case upstream wants to do a newer release without modifying the tarball name.
This leads to:

%define stamp 19981218

Source0:        uread-%{stamp}.tar.gz
# unversioned upstream source, downloaded with wget -N
# renamed to uread-YYYYMMDD.tar.gz
#Source0:        http://www.engineers.auckland.ac.nz/~snor007/src/uread.tar.gz


Jochen objects to that, saying that the Source should be downloadable, like
Source0:        http://www.engineers.auckland.ac.nz/~snor007/src/uread.tar.gz

What do you think about that issue? What do you think is best practice
and why?
