Comment(by jhpalmieri):
It would be great to have this in Sage!
I'm seeing some problems with the patch. First, it doesn't apply cleanly
to Sage 4.7.alpha1. I haven't tried applying to 4.6.2. I rebased it by
hand.
Second, the change
{{{
#!diff
- block_name, block_length, _ =
re.split(length_pattern,block)
+ block_name, block_length, _ = re.split(pattern,
block.strip())
}}}
in term_order.py is problematic, because "pattern" is not defined
anywhere. Replacing it by "length_pattern" seems to work.
Third, in multipolynomial_ideal.py, {{{_groebner_basis_libsingular}}} is
being called with keywords "deg_bound" and "mult_bound", but it doesn't
accept those keywords as valid arguments. Should we add {{{*args,
**kwds}}} to the argument list? Or should those keywords be dealt with
explicitly? I tried adding generic {{{*args}}} and {{{**kwds}}}, but
doctesting on that file segfaults.
When I doctest the whole Sage library after making these changes, I get
the following failures:
{{{
The following tests failed:
sage -t -long -force_lib

}}}
On one machine, I also had this failure:
{{{
sage -t -long -force_lib
devel/sage/sage/rings/polynomial/multi_polynomial.pyx # Killed/crashed
}}}
