Update Singular to 3-1-3-3

[malb]

Singular spkg upgrade

Singular 3-1-2 fixes a critical bug, cf. #10902. There are more bugfixes in the newest stable release. We should update as soon as possible.

Sage libsingular upgrade

There are various issues where currRing is not correctly set. Some of these are triggered by refcounting the rings and freeing them when they are no longer needed, see the dependency ticket #11339.

Installation instructions

• Install: http://boxen.math.washington.edu/home/jdemeyer/spkg/singular-3-1-3-3.p1.spkg

• Apply the two dependency patches from Refcounting for Singular rings #11339

• Apply: attachment: 10903_flat.patch

Depends on #11339

Last time I tried libsingular from 3.1.2 didn't play well with sage (sage couldn't build). It is documented somewhere on sage-devel.

sorry for the double pasting the mouse is vintage.

Updating singular to at least 3-1-3 (if it's out...) will also help the ARM port, as it's one of the few packages which still give issues with 4.6.2.

Indeed 3-1-3 is out now. Already 3-1-2 adds a lot of functionality for polynomials over the integers which would be very helpful to have in Sage!

Trying to compile libsingular with this version and trying to link it to sage is on my TODO list. The singular 3-1-3 executable as called by the pexpect interface breaks a few doctest because normalization has been changed.

Just FYI, I'm cutting a p10 shortly with a very small fix for Cygwin in it (see #11550), so if someone if making this package, it would be great to base off that.

Replying to @SnarkBoojum:

Cf. #10810.

If someone touches the Singular spkg, please also add a patch for #11645 in case it should then still be necessary. (I've submitted one upstream, see http://www.singular.uni-kl.de:8002/trac/ticket/352#comment:15).

FWIW, the Singular spkg from #11550 will probably become a p12, since #11663 meanwhile provides a p11 (which Karl-Dieter's will have to get rebased on again).

I'll then perhaps provide a p13 based on that fixing #11645. :)

Anyway, I guess upgrading Sage's Singular will be attempted during the Sage/Singular Days in Kaiserslautern at the end of September, so we have some time until then...
