attachment:trac_5133-multi_modular_tests.patch adds doctests and fixes some possible segfaults by reorganizing the memory allocations in sage.ext.multi_modular
. Changes introduced by the patch are:
- 100% coverage
- refactor memory management
- use random primes
- set upper/lower bounds for moduli on initialization

Review
- typo:
l_bound
->u_bound
in docstring - the string representation is quite unusual, not sure if that's desired.
isinstance(val, list)
should allow more typesisinstance(val, (list,tuple,GeneratorType))
- Why is it okay to use
proof=False
for random integers, because they are so small anyway? That should be added as a comment. __cmp__
wants you to return -1,0,1 and notTrue

Replying to malb:
- typo:
l_bound
->u_bound
in docstring
Fixed.
- the string representation is quite unusual, not sure if that's desired.
Changed it to:
sage: from sage.ext.multi_modular import MultiModularBasis_base sage: mm = MultiModularBasis_base([3, 5, 7]); mm MultiModularBasis with moduli [3, 5, 7]
isinstance(val, list)
should allow more typesisinstance(val, (list,tuple,GeneratorType))
Done.
- Why is it okay to use
proof=False
for random integers, because they are so small anyway? That should be added as a comment.
I'd forgotten that I put that in. Good catch. I removed that argument, so we use the global flag now.
__cmp__
wants you to return -1,0,1 and notTrue
orFalse
, cf. http://docs.python.org/reference/datamodel.html
Fixed. Who would compare these things anyway? :)
INPUT::
->INPUT:
, it doesn't get two : because the following block is not literal
Fixed.
- patch applies cleanly against 4.1
- doctest failures:
Doh! I only doctested the sage/matrix
directory. Apparently the only user of MultiModularBasis
, namely matrix_integer_dense.pyx
didn't have doctests for it. Now it does.

all tests pass, issues were addressed.

I got a hunk failure when applying trac_5133-multi_modular_tests-take2.patch
:

Here's the hunk that failed:
--- arith.py +++ arith.py @@ -915,6 +915,9 @@ the function uses a pseudo-primality test, which is much faster for really big numbers but does not provide a proof of primality. If None, uses the global default (see sage.structure.proof) + + - ``lbound`` - an integer >= 2 + lower bound for the chosen primes EXAMPLES::
This is because I previously applied the patches at #6529. The failure has been manually resolved so the docstring of random_prime
in sage/rings/arith.py
now reads:
Returns a random prime p between `lbound` and n (i.e. `lbound <= p <= n`). The returned prime is chosen uniformly at random from the set of prime numbers less than or equal to n. INPUT: - ``n`` - an integer >= 2. - ``proof`` - bool or None (default: None) If False, the function uses a pseudo-primality test, which is much faster for really big numbers but does not provide a proof of primality. If None, uses the global default (see :mod:`sage.structure.proof.proof`) - ``lbound`` - an integer >= 2 lower bound for the chosen primes
The patch trac_5133-take2-rebased.patch
is a rebase of trac_5133-multi_modular_tests-take2.patch
that depends on first applying the patches at #6529.

Oops... can I get someone to do a quick review of the rebased patch?

I changed the error message random_prime()
gives when lower_bound
is < n
.
Positive review for the rebased patch.

This will have to wait for Sage 4.1.1.alpha1. Apparently, I accidentally closed this as being merged in 4.1.1.alpha0.
