Comment (by SimonKing):
I only find two files in sage/rings/ where the string "._modulus" occurs:
polynomial_ring.py and polynomial_zz_pex.pyx:
{{{
devel/sage/sage/rings/polynomial/polynomial_zz_pex.pyx: c =
parent._modulus
devel/sage/sage/rings/polynomial/polynomial_zz_pex.pyx: d =
parent._modulus.ZZ_pE(list(x.polynomial()))
devel/sage/sage/rings/polynomial/polynomial_zz_pex.pyx: d =
parent._modulus.ZZ_pE(list(e_polynomial))
devel/sage/sage/rings/polynomial/polynomial_zz_pex.pyx: d =
self._parent._modulus.ZZ_pE(list(left.polynomial()))
devel/sage/sage/rings/polynomial/polynomial_zz_pex.pyx: _a =
self._parent._modulus.ZZ_pE(list(a.polynomial()))
devel/sage/sage/rings/polynomial/polynomial_zz_pex.pyx:
self._parent._modulus.restore()
devel/sage/sage/rings/polynomial/polynomial_zz_pex.pyx:
self._parent._modulus.restore()
devel/sage/sage/rings/polynomial/polynomial_zz_pex.pyx:
left._parent._modulus.restore()
devel/sage/sage/rings/polynomial/polynomial_zz_pex.pyx:
self._parent._modulus.restore()
devel/sage/sage/rings/polynomial/polynomial_ring.py:
self._modulus = ntl_ZZ_pEContext(ntl_ZZ_pX(list(base_ring.polynomial()),
p))
}}}
Hence, it should be easy to find out which of the few locations is
actually involved.
