method => [with patch, needs work] make
polynomial truncation cpdef method
* milestone: sage-3.2 => sage-3.2.1
Comment:
This patch causes the following doctest failures:
{{{
sage -t -long devel/sage/sage/schemes/elliptic_curves/padics.py #
1 doctests failed
sage -t -long devel/sage/sage/rings/power_series_ring_element.pyx
# 2 doctests failed

sage -t -long devel/sage/sage/crypto/lfsr.py # 5 doctests failed
}}}
The error seems to always be
