== Review PolyBoRi 0.8.0 patch ==

'''People''': Martin, Alexander (offsite)

 * [[http://trac.sagemath.org/sage_trac/ticket/11575|#11575]]

Martin reviewed it mathematically. The patch was rebased to 4.7.2alpha3, the spkg got the improved sse2-flags detection from 0.8.1.
(Final) tests are running currently.

Sage/Singular Days Projects

Update Singular spkg

People: Simon, Burcin, Martin

working on prerelease of Sage-4.7.2.alpha3 dated Sept 19, 2012 md5sum: ad021855ae07ecdd1cdcc7b973c9cdba

  • #10903 update Singular

  • #10810 Singular doesn't build on ARM

  • #11769 Singular doesn't build on Ubuntu Oneiric

  • #10902 factorization of multivariate polynomials

Update the Singular interface to work with libpolys

People: Volker, Burcin, Oleksandr

  • There were many changes to libSingular as part of the refactoring effort. The Sage interface needs to be adapted to these. This should be a matter of renaming the functions that are called in Sage and adding the current ring as an argument (modulo bugs in libpolys).
  • create spkg for refactored Singular
  • search/replace calls to libSingular in the Sage library to get the interface to compile & link

Fix the building of spielwiese Singular (libpolys)

People: Volker, Oleksandr

  • parallel building make -j used to fail because of generated sources (e.g. feOpt.inc)

  • make install should install everything needed for make distcheck

  • tests run via make check should be able to find resources (e.g. gftables) - cleate symlink or set Singular environment variables?

Refactored Singular should pass it's test suite

People: Burcin, Oleksandr, Hans, Volker

Bug hunt through Singular kernel code. An adventure no hacker can resist.

Compiler warnings

People:

There are lots of compiler warnings...

Plural/SCA

People: Oleksandr

  • Bug hunt at PLURAL/SCA kernel code: (left) std etc...

Try out some dynamic modules

People: Oleksandr

  • Try building & using dynamic modules

Blackbox objects

People: Oleksandr

  • Try building & using blackbox objects, e.g. coefficient domain as a wrapper for coeffs

Interface to Singular's modules

People: Hiep, Burcin, Simon

  • This shouldn't be so hard since libSingular uses the same type for polynomials and module elements

Review Simon's letterplace patches

People: Simon, Burcin, Alexander (offsite)

  • #7797

  • #11115 make cached methods faster - dependency of #7797 (Volker)

Plural interface

People: Burcin, Simon, Alexander (offsite)

Exponent overflow

People: Simon

  • Working on the Plural interface, we found that Sage does not raise an overflow error when it should. Example: With P.<x,y>=QQ[], y^2^30 returns a correct result; in P.<x,y,z>=QQ[], an overflow occurs, but instead of raising an error, y^2^30 returns zero.

Use libpolys for function field arithmetic

People: Burcin

FLINT integration in Singular

People: Fredrik, MartinL, Christian

  • Add missing utility and conversion functions to FLINT
  • Use FLINT in Singular
  • Benchmark against NTL version

Beginner tickets

People: Hiep, Burcin to practice preparing and submitting patches, for people new to the Sage development process:

Fast containers for objects and morphisms of a category

People: Simon

  • See #10667 Morphisms and Objects of Categories

Improve/Review citation library

People: Niels, Burcin, (and somebody else?)

#3317 bitbucket

  • #11851 #11852 split off pybtex package to a separate ticket (submit as an optional package first)

  • Add more examples of citations
  • add sage's citation

  • Open a ticket for matplotlib not to include an extra version of pyparsing.

Fix reference counting of Singular rings

People: Volker, Burcin, Martin

Review PolyBoRi 0.8.0 patch

People: Martin, Alexander (offsite)

Martin reviewed it mathematically. The patch was rebased to 4.7.2alpha3, the spkg got the improved sse2-flags detection from 0.8.1. (Final) tests are running currently.
