dozens of failures in magma optional test suite on skynet (eno) with sage-4.3

[williamstein]

I ran the magma optional test suite on skynet (eno):

./sage -t --only_optional=magma devel/sage/sage > magma.out&

And the failures are:

        sage -t --only_optional=magma "devel/sage/sage/rings/polynomial/pbori.pyx"
        sage -t --only_optional=magma "devel/sage/sage/rings/polynomial/multi_polynomial_ring_generic.pyx"
        sage -t --only_optional=magma "devel/sage/sage/rings/polynomial/term_order.py"
        sage -t --only_optional=magma "devel/sage/sage/rings/polynomial/multi_polynomial_ideal.py"
        sage -t --only_optional=magma "devel/sage/sage/crypto/mq/mpolynomialsystem.py"
        sage -t --only_optional=magma "devel/sage/sage/schemes/hyperelliptic_curves/hyperelliptic_g2_generic.py"
        sage -t --only_optional=magma "devel/sage/sage/symbolic/expression.pyx"
Total time for all tests: 364.0 seconds

this is the output of running the test suite, showing the actual failures.

I tested again using the new magma V2.16-7 with sage-4.3.5.

[wstein@eno sage-4.3.5]$ magma
Magma V2.16-7     Tue Apr  6 2010 11:14:18 on eno      [Seed = 3125460604]
Type ? for help.  Type <Ctrl>-D to quit.

There are now even more failures. I've attached a new test log created using the following on eno:

./sage -tp 10 -only_optional=magma devel/sage/sage

[williamstein]

it got much worse!

Attachment: magma-sage-4.3.5.out.gz

Attachment: trac_7870.patch.gz

This fixes all the doctest issues on eno with magma V2.16-7

I am testing this now with magma V2.16-1 and will report back. It will not be a clean result, since I already saw

    sage: magma(f)                         # optional - magma

Got:
    sin(log(x) + cos(x^2))
