[Debian-science-sagemath] Required tasks for sage in stretch

[Tobias Hansen]

Hi,

I'm a bit worried that we might not achieve the goal to get sage into
stretch, if we don't focus on the essential tasks.[1] If we do not get
all of the following things done in the next 3 or 4 weeks, there will
simply be no sage in stretch.

* gap/libgap - Jerome, do you have a plan to resolve this?

* maxima - even updating sage to maxima 5.38.1 is hard (see [2]) and
then there is the gcl vs ecl issue. I begin to think the only way to
solve this in time is to have our own package of maxima 5.35.1 with ecl
and fasl library.

* ecl - the one fix I applied does not migrate to testing due to a
deadlocked situation with libatomic-ops (unfixable (?) RC bug). Maybe
this can be resolved by asking for removals of libatomic-ops packages
for the failing architectures from testing. Since the RC bug is also in
testing, the package should then migrate, right?

* planarity - We need have to figure out how to use the new version
packaged in Debian.

* cython - We need to fix RC bug #833288 for testing migration and make
sure cython 0.25 gets packaged.

* pyzmq - RC bugs need to be fixed for testing migration.

* linbox - I might need to close RC bugs by disabling tests.

* sagenb - Is someone taking care of this? What's the status?

* jupyter-sphinx-theme - Jerome, can this be uploaded?

* jupyter-notebook - Gordon, can this be uploaded?

* ipywidgets, widgetsnbextension, thebe - ? (Are these essential?)

* sagemath - fix doctests, disable doctests we can't fix, revise
patches, polish packaging, etc.


[1] I really hope noone gets offended by this, but singular 4.0.3-p5 and
pynac 0.7 are not on this list. We should probably also stop worrying
about jmol. It would be a pity if we can't get sage into stretch because
we get carried away doing other things.
