Bray" Date: Thu, 16 Jun 2016 15:06:09 +0000 Subject: [PATCH 297/788] Update some patches so that *all* patches to spkgs are applied with 'patch -p1' from the root of the upstream source. There were only a handful of oddballs in this regard: * cddlib * gfan * pygments (In the case of pygments the patches were formatted correctly, but were being applied *before* `cd src/` instead of after.) --- build/pkgs/cddlib/package-version.txt | 2 +- .../pkgs/cddlib/patches/lib-src-gmp_Makefile.am.patch | 6 +++--- .../pkgs/cddlib/patches/lib-src-gmp_Makefile.in.patch | 6 +++---

My simple modiifications increase the speed of the inversion by a large factor if the denominator of the number field element is large. Moreover, in fact this modification makes NTL fail less often(!) and the examples in Trac #20693 in fact don't run into the NTLError anymore now. --- src/sage/libs/ntl/ZZX.pxd | 2 +- src/sage/modular/hecke/module.py | 12 ++++++ .../number_field/number_field_element.pxd | 2 +- .../number_field/number_field_element.pyx | 38 +++++++++++++++---- 4 files changed, 45 insertions(+), 9 deletions(-) diff --git a/src/sage/libs/ntl/ZZX.pxd b/src/sage/libs/ntl/ZZX.pxd index 9d83a7d2f10..63283d0f1dd 100644 --- a/src/sage/libs/ntl/ZZX.pxd +++ b/src/sage/libs/ntl/ZZX.pxd @@ -35,7 +35,7 @@ cdef extern from "sage/libs/ntl/ntlwrap.cpp": void ZZX_div_ZZ "div"( ZZX_c x, ZZX_c a, ZZ_c b) long ZZX_deg "deg"( ZZX_c x ) void ZZX_rem "rem"(ZZX_c r, ZZX_c a, ZZX_c b) - void ZZX_XGCD "XGCD"(ZZ_c r, ZZX_c s, ZZX_c t, ZZX_c a, ZZX_c b, long deterministic) + void ZZX_XGCD "XGCD"(ZZ_c r, ZZX_c s, ZZX_c t, ZZX_c a, ZZX_c b, long deterministic) except + void ZZX_content "content"(ZZ_c d, ZZX_c f) void ZZX_factor "factor"(ZZ_c c, vec_pair_ZZX_long_c factors, ZZX_c f, long verbose, long bnd) diff --git a/src/sage/modular/hecke/module.py b/src/sage/modular/hecke/module.py index f28c3d1aece..02d0e433728 100644 --- a/src/sage/modular/hecke/module.py +++ b/src/sage/modular/hecke/module.py @@ -1123,6 +1123,18 @@ def dual_eigenvector(self, names='alpha', lift=True, nz=None): sage: ModularSymbols(14).cuspidal_subspace().simple_factors()[1].dual_eigenvector() (0, 1, 0, 0, 0) + + We check that :trac:`20693` is fixed + :: + + sage: M=ModularSymbols(DirichletGroup(23).gen()**2,6,sign=1) + sage: A=M.cuspidal_subspace().new_subspace().decomposition()[0] + sage: v = A.dual_eigenvector() # long time (about 2:45min on a 2014 MacBook Pro) + sage: v[1].trace() # long time + -6916377304966118028840154319744623313289720847089107292253549548960207679321409496876643/2275702878094574968149055169963412278190068684049608491395136083103585448350159960807 + + + """ # TODO -- optimize by computing the answer for i not None in terms # of the answer for a given i if known !! diff --git a/src/sage/rings/number_field/number_field_element.pxd b/src/sage/rings/number_field/number_field_element.pxd index 8b27454cc51..0971b7aaa6a 100644 --- a/src/sage/rings/number_field/number_field_element.pxd +++ b/src/sage/rings/number_field/number_field_element.pxd @@ -26,7 +26,7 @@ cdef class NumberFieldElement(FieldElement): cdef void _ntl_coeff_as_mpz(self, mpz_t z, long i) cdef void _ntl_denom_as_mpz(self, mpz_t z) - cdef void _invert_c_(self, ZZX_c *num, ZZ_c *den) + cdef void _invert_c_(self, ZZX_c *num, ZZ_c *den) except * cdef void _reduce_c_(self) cpdef ModuleElement _add_(self, ModuleElement right) cpdef ModuleElement _sub_(self, ModuleElement right) diff --git a/src/sage/rings/number_field/number_field_element.pyx b/src/sage/rings/number_field/number_field_element.pyx index 15bb506f108..23711f9f2b7 100644 --- a/src/sage/rings/number_field/number_field_element.pyx +++ b/src/sage/rings/number_field/number_field_element.pyx @@ -40,8 +40,10 @@ from sage.libs.gmp.mpz cimport * from sage.libs.gmp.mpq cimport * from sage.libs.mpfi cimport mpfi_t, mpfi_init, mpfi_set, mpfi_clear, mpfi_div_z, mpfi_init2, mpfi_get_prec, mpfi_set_prec from sage.libs.mpfr cimport mpfr_less_p, mpfr_greater_p, mpfr_greaterequal_p +from sage.libs.ntl.error import NTLError from cpython.object cimport Py_EQ, Py_NE, Py_LT, Py_GT, Py_LE, Py_GE from sage.structure.sage_object cimport rich_to_bool +from sage.all import cputime import sage.rings.infinity import sage.rings.polynomial.polynomial_element @@ -2258,14 +2260,14 @@ cdef class NumberFieldElement(FieldElement): """ return long(self.polynomial()) - cdef void _invert_c_(self, ZZX_c *num, ZZ_c *den): + cdef void _invert_c_(self, ZZX_c *num, ZZ_c *den) except *: """ Computes the numerator and denominator of the multiplicative inverse of this element.
