12793 Fix __cmp__ tests in sage/combinat/root_system/type_dual.py jdemeyer sage-combinat "The following tests were added to `sage/combinat/root_system/type_dual.py` by #6588:
{{{
def __cmp__(self, other):

EXAMPLES::
sage: B4 = CartanType(['B', 4])
sage: B4dual = CartanType(['B', 4]).dual()
sage: F4dual = CartanType(['F', 4]).dual()
sage: cmp(F4dual, F4dual)
0
sage: cmp(F4dual, B4dual)
1
sage: cmp(B4dual, F4dual)
-1
sage: cmp(B4dual, B4)
1
.. todo:: do we really need a cmp, or just eq?
""""""

But whether `cmp()` outputs 1 or -1 is essentially arbitrary. This must be fixed immediately." defect closed blocker sage-5.0 combinatorics fixed sage-5.0.beta12 Jeroen Demeyer Nicolas M. Thiéry N/A
