Sage Days 23.5 Coding Sprint Projects
Singular Parallel Build
Trac #9497: Fix the Singular spkg so it can take advantage of building in parallel
Doctest the Free Algebra Quotient code
The file SAGE_ROOT/devel/sage/sage/algebras/free_algebra_quotient.py has no doctests. Get it to 100% coverage. The point of this is that it is related to wrapping something like letterplace.
== Letterplace ==
Do a very basic wrapping of letterplace for Sage. Use this to replace some of the lame old code in the SAGE_ROOT/devel/sage/sage/algebras/ directory.
error: out of memory
Trac #5313. Patch singular so that when it runs out of memory the error message says "singular" in it. Moreover, replace the exit(1) or whatever by something that can be trapped via _sig_on/_sig_off.
Relative number field arithmetic
- Arithmetic in relative numbers fields is sometimes very slow. This could be done using multivariate polynomial ring quotients via libsingular, which would be extremely fast in some cases. There is some cleverness that I do *not* know how to do for inverting elements -- hence it would be good to do this here with singular people around.
Stuff that isn't clearly Singular related
Make an @fork decorator
Simon King mentioned that sometimes his code crashes/leaks/etc. So make it so one can do:
@fork
def f(x,y,z,...):
...and then f gets computed in a blocking forked process, and the result is returned via pickling. This is 100% to thwart mem leaks, segfaults, and guaranteed timeout possibility. This could be basically just a light wrapper around @parallel(1). Also, make a global flag to turn this off, so @fork does nothing.
Sage Nagbot could Doctest some tickets
The Sage Nagbot could be made able to run doctests for a ticket, say in the one obvious case where there is precisely one patch attached to the ticket, and it is set to "needs review". The nagbot code is here.
