Hi,
Here is the somewhat detailed plan for SAGE-1.8. See also
http://sage.math.washington.edu:9002/sage_trac/milestone/sage-1.8
I spent a lot fo time making the list of trac bugs below. These are all fairly
important usually intersting and important bugs that still persist in SAGE-1.6.
Help appreciated on any of them, though don't worry if you're clueless about
them. I plan to make more details about how to fix each when sage-1.7 is done.
== SAGE-1.8: Goal Date is Jan 19, 2007 ==
== Bug fixing ==
* Fix the fixable important SAGE bugs listed in trac (ones below not fixed
will be fixed for sage-1.9):
- trac #34 -- modular symbols bug
- trac #39 -- implement equality testing for ZZ[x,y,...] using M2 (or give
error message)
- trac #189 -- minor sage notebook formating bug
- trac #45 - ntl modulus reset correclty.
- trac #130 - problem with multiline history recall in IPython
- trac #149 -- failure in E.sha_an()
- trac #151 -- clisp.run's left running -- it's still happening though
many cases have been fixed.
SOLVE this frickin' zombie problem somehow once for all...
- trac #168 -- Plot bounds ignored when frame=True
- trac #177 -- pari interface -- new arithmetic model
- trac #185 -- implement backoff when queuing for notebook updates.
- trac #188 -- Python's builtin round function is funny since it always
coerces to float
- trac #32 -- missing coercion of polynomials between different bases
functionality
- trac #35 -- load "adosfile.sage" breaks
- trac #63 -- in safari notebook, tab key inserts tab AND moves to
beginning of cell
- trac #96 -- time command doesn't work in .sage files !?
- trac #154 -- gfan changes broke interface slightly.
- trac #156 -- freeze of gfan (actually singular -- not gfan's fault)
- trac #181 -- recursive load and symbol??
- trac #148 -- links in saved notebook worksheets
== Code ==
* Symbolic calculus package (bobby m. etc): update
* p-adic (David Roe): update
* Integrate in code from Ling Long et al for congruence subgroups
* Pyrex: interval arithmetic ring (volunteers?)
* Pyrex: generic polynomial ring elements
* Pyrex: generic power series over arbitrary ring
* Pyrex: generic laurent series over arbitrary ring
* Optimize matrix algebra over QQ, GF(p), ZZ (Stein, Bradshaw, Ifti B)
- matrix permanents
- multimodular algorithms
- more optimizations for special rings (e.g., copy, etc.)
- use ssmod as an example to motivate this
- In the file matrix/docs.py is a list of base rings where specialized
matrix classes should be implemented. More specialized vector space and free
module classes also need to be implemented in SageX.
* Improve modular symbols and modular forms. Some algorithms haven't been
completely implemented. (Some do things I never implemented in MAGMA.)
- finish modular forms algorithms
- enable modular forms doctests and test and fix
- finish implementing modular symbols factorization in general
(eisenstein part is currently not fully implemented)
- computation of period mapping
- more testing, examples, etc., for modular symbos for GammaH
== Documentation ==
* SAGE Constructions (Stein, Kohel, Joyner): Update the constructions guide
to use "modern SAGE" constructions to solve the problems. No dirty tricks
except in a dirty tricks section.
