- It would be nice to use and improve the independent Cython library
cypari developed by M.
Culler and N. Dunfield for Snappy. Have a look at
the [cypari src]((https://pypi.python.org/pypi/cypari) stuck at version
2.5.5 of pari!!
- The file “gen.pyx” (Cython side) can be automatically generated from
“pari.desc”, see Sage
ticket #17631
- (done) Implement error handling using [cb_pari_err_handle], see Sage ticket #14894
- Upgrade PARI! There is a huge difference between 2.7.X (stable
release) and the current 2.8.X (git master). Hence effort put for
versions 2.7.X will basically be useless for 2.8.X (see trac Sage ticket #16997)
- Talk about the patches
- Avoid copy from the pari stack. After each libpari function call in
Sage, there is a copy of the result and cleaning of the pari stack. It
should be possible to use pointer on the pari stack directly. It is not
clear how much we will win as the results are often small (needs
some design discussion)
- Join forces with other interface (i.e. gp, Julia)
