Update Singular spkg
People: Simon, Burcin, Martin
working on prerelease of Sage-4.7.2.alph3 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: 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
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.
build refactored Singular: http://github.com/Singular2/singular2.github.com/wiki/New-TODOs
run test suite with debug version of Singular which dumps stack traces on error. (kernel/cntrl.cc should be modified to define DEBUG_STOP instead of INTERACTIVE)
list of test results (temporarily)
- Monday morning: 595 failing tests
- Tuesday morning: 543 failing tests
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)
Plural interface
People: Burcin, Simon, Alexander (offsite)
Rebase the patch at #4539 plural wrapper to 11068 implementation of one and two sided ideals of noncommutative rings
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
- libpolys has better function field arithmetic now, we should wrap that in Sage.
This is also relevant #9054 create a class for basic function field arithmetic
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:
http://trac.sagemath.org/sage_trac/ticket/11850 choose the random elements of the ideals.
.hilbert_series(), .hilbert_function() methods of ideals http://trac.sagemath.org/sage_trac/ticket/11855.
add .saturation(), .blow_up_ideal() methods in the multivariate polynomial ideal class
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?)
#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
