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.
- http://pari.math.u-bordeaux.fr/cgi-bin/bugreport.cgi?bug=1192 (#10767)
We will do this by updating to PARI version 2.4.4.BETA, which is equal to svn revision 13169.
See also #9343, #10430 (previous PARI upgrades). See also #10247 (Sage 4.6 has PARI problems on Cygwin). We need to fix also lcalc: #11321.
Spkg: http://boxen.math.washington.edu/home/jdemeyer/spkg/pari-2.4.4.p0.spkg
Apply 11130_sagelib.patch and trac_11130-doctest-poly.patch and 11130_sagelib32.patch.

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).
comment:24 Changed 10 years ago by

- 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.

In sage/rings/number_field/number_field.py
, there is a test which fails only when -long
is not used.

New patch fixes the long time issue (by setting a random seed explicitly). I will test on a Mac OS X 10.4 32-bit PPC system.

... which gave several more failures:
sage -t devel/sage-main/sage/rings/number_field/number_field.py # 1 doctests failed sage -t devel/sage-main/sage/schemes/elliptic_curves/ell_number_field.py # 2 doctests failed sage -t devel/sage-main/sage/schemes/elliptic_curves/ell_rational_field.py # 1 doctests failed sage -t devel/sage-main/sage/rings/number_field/number_field_element.pyx # 1 doctests failed sage -t devel/sage-main/sage/rings/polynomial/polynomial_quotient_ring.py # 3 doctests failed sage -t devel/sage-main/sage/rings/integer.pyx # 1 doctests failed
Details:
sage -t "devel/sage-main/sage/rings/number_field/number_field.py" ********************************************************************** File "/home/john/sage-4.7.alpha5/devel/sage-main/sage/rings/number_field/number_field.py", line 3616: sage: L.factor(a + 1) Expected: (Fractional ideal (1/2*a*b + a + 1/2)) * (Fractional ideal (-1/2*b - 1/2*a + 1)) Got: (Fractional ideal (-1/2*a*b - a - 1/2)) * (Fractional ideal (1/2*b + 1/2*a - 1))
is trivial,
sage -t "devel/sage-main/sage/rings/number_field/number_field_element.pyx" ********************************************************************** File "/home/john/sage-4.7.alpha5/devel/sage-main/sage/rings/number_field/number_field_element.pyx", line 1142: sage: t = (2*a + b)._rnfisnorm(L); t[1] Expected: (b - 2)*a + 2*b - 3 Got: (-4*b - 5)*a + 5*b + 6
needs looking at,
sage -t "devel/sage-main/sage/rings/polynomial/polynomial_quotient_ring.py"
are just like the ones I fixed before on the other machine, and
sage -t "devel/sage-main/sage/rings/integer.pyx" ********************************************************************** File "/home/john/sage-4.7.alpha5/devel/sage-main/sage/rings/integer.pyx", line 4389: sage: 7._bnfisnorm(CyclotomicField(7)) Expected: (-zeta7 + 1, 1) Got: (-zeta7^5 + zeta7^4, 1)
is also trivial (multiplying by a power of zeta does not change the norm!).
That's all I have time for today, so I hope things look similar on the other 32-bit system being tested.
comment:36 Changed 10 years ago by
- Description modified (diff)
I have added a new patch (which affects 4 files in sage/rings) after which all doctests pass on both 32- and 64-bit, apart from the simon-related ones.
That means that it is time to check #11005 on top of all this.

A reasonable assumption, but...for a while now I have used Sage's Pari and NTL builds rather than building them myself independently, so I cannot yet confirm. (However, eclib's use of Pari is minimal, it's only for integer factorization.)
I am also preparing a new version of eclib, so I will combine these two tasks, though I don't have any time for this this week.

I built Sage completely from scratch with the new PARI and lcalc packages, everything works. All tests pass except for the ones related to simon_two_descent.

So is the "Needs work" just because this ticket is dependent on #11005? I am planning to look now at the doctest failures relating to the Simon scripts and fix them, so that this ticket can then be closed, and the additional work needed on #11005 can depend on this.
