Comment:
With #12808, #12875 and #12877 applied on top of sage-5.1.notebook, all
doctests pass. But when adding the patch from here, there are two
problems:
{{{
sage -t -force_lib "devel/sage/sage/libs/singular/ring.pyx"
sage -t -force_lib
"devel/sage/sage/rings/polynomial/multi_polynomial_libsingular.pyx"
}}}
Namely:
{{{
sage -t -force_lib "devel/sage/sage/libs/singular/ring.pyx"
**********************************************************************
File
"/mnt/local/king/SAGE/experiment/notebook/sage-5.1.notebook/devel/sage/sage/libs/singular/ring.pyx",
line 469:
sage: ring_ptr in ring_refcount_dict
Expected:
False
Got:
True
**********************************************************************
}}}
and
{{{
sage -t -force_lib
"devel/sage/sage/rings/polynomial/multi_polynomial_libsingular.pyx"
**********************************************************************
File
"/mnt/local/king/SAGE/experiment/notebook/sage-5.1.notebook/devel/sage/sage/rings/polynomial/multi_polynomial_libsingular.pyx",
line 418:
sage: len(ring_refcount_dict) == n
Expected:
True
Got:
False
**********************************************************************
}}}
So, apparently it is only a single problem.
