The third issue I se with sage-4.4.2-alpha0 is the following. I did
the usual " export SAGE_BINARY_BUILD=yes " (the PIL spkg does not
build for me without this additional environment variable, something
that is "accepted") and " export MAKE='make -j2' " (my machine has a
Core2Duo CPU, so there), an
The second problem occurs in a "long" only doctest, but probably
occurs now on any machine. From what I guess skipping through the
patches newly applied to sage-4.4.2.alpha0, I'd suspect " #8479:

On MacIntel OS X 10.4, building sage-4.4.2.alpha0 from scratch, the
build finishes, but I see three new issues. I'll describe them in
three different posts. (Note that with sage-4.4.1, on the same
machine, I had done a full "make testlong", which succeeded
flawlessly). The first on seems to be a tr
Hi,
I'm giving this tutorial on Sage:

at the Texas Advanced Computing Center's Scientific Software Day:

It's really amazing how arbitrary the possible choices of topics are
for a tutorial...

I have found some doctest failures that could take a while to resolve.
So getting this release out early should help with resolving them.
On Fedora 12, 64 bit all troubles seem far away!

Does feature freeze mean that patches adding lots of doctests will not
be included? I spent hours on
http://trac.sagemath.org/sage_trac/ticket/8799 after a request to work
on the worst offenders, but no-one has reviewed it yet. It is 99% in
the docstrings so would not be a hard job...

Hi folks,
The Sage 4.4.2 release cycle is now in feature freeze. We will only
resolve issues and doctest failures to stabilize the final release
candidate.

Hello Rogério,
You are right that I don't have the time to maintain sagemath -- I'd be
very happy to move to a team maintenance structure. I've copied several
folks who have expressed interest in updating the Sage packaging over the
last few weeks, who may help provide the initial team.

I'm using toric varieties for my research, mainly for Calabi-Yau
manifolds in string theory. So my goal for the toric varieties package
is to implement everything that is known ;-)
