Comment:
I can confirm that the doctest now passes on a 32-bit build of
sage-4.7.alpha1 on !OpenSolaris 06/2009 (Intel Xeon chip)
{{{
sage -t -long -force_lib
"devel/sage/sage/rings/number_field/number_field.py"
[48.8 s]
----------------------------------------------------------------------
All tests passed!
Total time for all tests: 48.8 seconds
}}}
Prior to adding the 3 patches to sage-4.7.alpha1, I got.
{{{
File "/export/home/drkirkby/sage-4.7.alpha1/devel/sage-
main/sage/rings/number_field/number_field.py", line 3035:
sage: K.selmer_group([K.ideal(2, -a+1), K.ideal(3, a+1), K.ideal(a)],
3)
Expected:
[2, a + 1, a]
Got:
[2, a + 1, -a]
}}}
I don't know enough about the maths to understand what the patch does, so
whilst it appears to fix the problems I see in sage-4.7.alpha1, I don't
feel I should give this a positive review - it needs a mathematician to
check it too.
