Hi Sebastian,
I was just wondering what was up with this ticket yesterday. If you think
this is eventually going to make it into FLINT itself, it may be better to
provide the C (or even a patched FLINT spkg). Otherwise, Cython is
preferable as many more people in the Sage community will be able and
willing to edit it.
Given the history of this ticket, I would be more comfortable with first a
very clean, straightforward implementation based on FLINT (without
avoiding allocation at all costs, the NULL denominator savings, etc.) and
get that fully vetted, refereed, and in. Hopefully that should be a
simpler task (i.e. less endless chasing down segfaults, random doctest
failures, and a much simpler referee process with a high confidence in the
correctness of the implementation). That should (I'd guess) already be a
significant performance improvement (right?). Once we've done that, then
we can go ahead and optimize things further.
