I've added pickling support to PPL, this is now part of this ticket.
comment:4 Changed 9 years ago by
- Dependencies set to #12159
Through the triangulation of polytopes, this depends on #12159
comment:5 Changed 9 years ago by
Volker, I'll try to review this this week if I can. If I forget feel free to ping me about it.
comment:6 Changed 9 years ago by
I'm having trouble applying your patches, it looks like this also depends on #11429.
comment:7 Changed 9 years ago by
- Dependencies changed from #12159 to #12159, #11429
Yes, that one needs to be reviewed as well.

I have the following patches applied on top of sage-4.8.alpha6 without problems:
[vbraun@volker-laptop-two hg]$ hg qseries trac_11429_native_enumeration_of_lattice_polytope_points.patch trac_11429_cythonize_lattice_points.patch trac_11429_fix_doctests.patch trac_12159_separate_triangulation_file.patch trac_12159_placing_triangulation.patch trac_12159_normal_cone.patch trac_11634_refactor_polyhedron.patch trac_11634_pickling_for_PPL.patch trac_11634_ppl_backend.patch
The patches might not apply cleanly older sage versions.
comment:10 Changed 9 years ago by
Thanks; I was working with an unoffical sage-4.8.rc1, I will switch to 4.8.alpha6 and try again in case that is the problem.
comment:11 follow-up: ↓ 12 Changed 9 years ago by
OK, I got it working now. Clearly PPL is much faster on some of my test examples, wow.

Replying to mhampton:

Oh yeah, working with toric varieties got much better once most basic operations were switched to PPL!
I am also the offending reviewer on #11429, dropping off the radar half-way. Will try to remedy it shortly, without forgetting #11599.

For sage-5.0.beta1, the numerial noise fix from #9958 changes one line of polyhedra.py, which causes trac_11634_refactor_polyhedron.patch to fail to apply.
5866c5866 < 0.8 --- > 0.8000...
comment:15 Changed 9 years ago by
- Status changed from needs_review to needs_info
I'm a little confused by the above numerical noise issue. After changing so that the patch would apply, the doctest failed. If I switch it to
sage: filled_poly.axes_width() 0.8...
then it works. I'm not sure if the "0.800..." makes sense on some other system or not.
Apart from that I think this all looks good. There is one other doctest failure in integral_points.pyx resulting from the Python switch to 2.7, line 688 needs to be changed to
OverflowError: Python int too large to convert to C long
instead of
OverflowError: long int too large to convert to int
With those changes I would be happy to give a positive review.
I haven't looked at #11429 and #12159 by themselves, but it would be nice to get this ticket into sage-5.0. I don't have a lot of time in the coming weeks but if Andrey can't review those I would try to check them out too.
comment:16 Changed 9 years ago by
I already fixed the OverflowError
error message in #11429. What output do you get for
filled_poly.axes_width()
the doctest works for me with 0.8
.
comment:17 Changed 9 years ago by
PS: #11429 is already reviewed ;-)
comment:18 Changed 9 years ago by
comment:19 Changed 9 years ago by
The way I understad it, #9958 changes the float printing to do the fuzzy zero automatically so its no longer necessary to add ellipsis.
comment:20 Changed 9 years ago by
OK, I guess its fine to change it back to a 0.8 then.
comment:21 Changed 9 years ago by
- Status changed from needs_info to needs_review
Updated patch for sage-5.0.beta4. I'm switching this back to "needs review" unless you think I haven't given enough info yet ;-)

I couldn't get the patchbot to apply the three patches. Also, there seems to now be a consensus that code lines with trailing whitespace are a Bad Thing. So I've done a single qfolded patch which is equivalent to Volker's three patches but with all trailing whitespace removed.
Apply trac_11634-folded.patch

Thanks David, that made things simpler for me to look at. Volker, my apologies for taking so long on reviewing this. I think this should be a great addition to sage-5.0.

Is it because some new stuff merged in alpha8 uses old polyhedra code and was not converted?

Question (likely dumb): could the behavior at this ask.sagemath question be related to this change (or #14175)? Thanks!
