Description (last modified by )
We need to add bugfixes for
- http://pari.math.u-bordeaux.fr/cgi-bin/bugreport.cgi?bug=1147 (#9334)
- http://pari.math.u-bordeaux.fr/cgi-bin/bugreport.cgi?bug=1153 (#10195)
- http://pari.math.u-bordeaux.fr/cgi-bin/bugreport.cgi?bug=1184 (related to #9937)
- http://pari.math.u-bordeaux.fr/cgi-bin/bugreport.cgi?bug=1185 (PARI bug discovered by a Sage doctest)
- http://pari.math.u-bordeaux.fr/cgi-bin/bugreport.cgi?bug=1186 (PARI performance regression discovered by a Sage doctest)
- http://pari.math.u-bordeaux.fr/cgi-bin/bugreport.cgi?bug=1187 (PARI bug discovered by a Sage doctest)
- http://pari.math.u-bordeaux.fr/cgi-bin/bugreport.cgi?bug=1188 (PARI bug discovered by a Sage doctest)
- #10240 (pari-2.4.3.svn-12577.p9 incorrectly checks for the shared library on Cygwin). We simply use the spkg patch from that ticket.
However, since adding more and more patches to PARI is becoming unmaintainable, we simply should move to a more recent svn revision instead of revision 12623 (pari-2.4.3). We plan to update to svn revision 13153.
See also #9343, #10430 (previous PARI upgrades).
See also #10247 (Sage 4.6 has PARI problems on Cygwin).
Preliminary spkg: http://boxen.math.washington.edu/home/jdemeyer/spkg/pari-2.4.4.svn13153.p0.spkg
All doctest failures related to simon_two_descent will be fixed in #11005 and should be ignored for this ticket.

After (1) Building a fresh 4.7.alpha5 from scratch, (2) installing the spkg lined here with "sage -f", (3) applying the patch here to the sage library and (4) running "sage -b", I find that the Sage build will not start up properly:
ImportError Traceback (most recent call last) ... /home/jec/sage-4.7.alpha5.11130/local/lib/python2.6/site-packages/sage/misc/functional.py in <module>() 36 37 ---> 38 from sage.rings.complex_double import CDF 39 from sage.rings.real_double import RDF, RealDoubleElement 40 /home/jec/sage-4.7.alpha5.11130/local/bin/gen.pxd in init sage.rings.complex_double (sage/rings/complex_double.c:15178)() ImportError: /home/jec/sage-4.7.alpha5.11130/local/lib/python2.6/site-packages/sage/libs/pari/gen.so: undefined symbol: defaultOut Error importing ipy_profile_sage - perhaps you should run %upgrade? WARNING: Loading of ipy_profile_sage failed.
so I cannot test anything.
Did I do something wrong?

Replying to cremona:
I am currently testing this. To avoid duplication of effort, I'll fix things I find in the elliptic_curves directory only.
Sounds good, I will look at everything else.
comment:23 Changed 10 years ago by
I added a patch which fixes the doctest failures in sage/rings/polynomial/polynomial_quotient_ring.py . In all cases the new output was equivalent to the old.
There are now just some failures in sage/schemes/elliptic_curves/ell_rational_field.py (2 doctests failed) and sage/schemes/elliptic_curves/ell_number_field.py (1 doctests failed).

- Reviewers set to John Cremona
- Status changed from needs_work to needs_review
ell_rational_field.py: only one failure, looks completely trivial but will be left until #11005 to be fixed.
ell_number_field.py: one failure, even more trivial: the final output is exactly the same as it was but the verbose output is a little different, so this can be easily cleaned up at #11005.
As far as I am concerned this needs *no more work* on this ticket, but I'll delay marking it positive review until the same is possible at #11005. Still, it certainly gets "needs review" on that basis.

This patch should also be tested on various systems first, PARI is known to produce different results on 32-bit and 64-bit systems.

Good point. I can test it on my 32-bit laptop.
