sage-4.0.2 release timeline
Nick Alexander
Craig Citro and I (Nick Alexander) are your humble release managers
for this iteration, sage-4.0.2.
The plan is to cut a release candidate Friday, June 12, probably
evening PST. The release itself will be Saturday, June 13. Hopefully
Minh will update the release notes and Harald the website shortly
afterward.
We are going to try to merge all the code on trac that currently has a
positive review. However, there are a significant number of patches
needing review; now is the time to campaign for reviews. Please email
reviewers ASAP! You can also add them to the cc field on trac,
possibly using the list on the front page of trac (http://trac.sagemath.org/sage_trac/
) to help map names to trac usernames. If you can't think of a
suitable reviewer for one of your patches, Craig and I will try to
assist.
We intend to upgrade the following software:
* Singular
* Scipy
* Numpy
* mpir
There was some talk about merging the categories code of the sage-
combinat group. Since much of this code is still under review, that
won't happen this iteration. Sorry! Hopefully a push can be made to
get this in for sage-4.1.

This is a relatively minor release but fixes some issues on Cygwin
which sage-cygwin currently patches, adds Tom Boothby's code for fast
perfect power testing, my one line factor program and Tom's heuristic
for a faster factoring routine for numbers less that one limb, etc.
I've also added the F_mpz module, which was specifically requested by
Fredrick Johansson, though it is only documented in the F_mpz.h file
at this stage, not the main pdf file and I have not added an F_mpz_cmp
function or the other functions Fredrick requested as yet.
I've valgrinded all the changed code and tested the release on 32 and
64 bit machines, including Cygwin.
This is not a critical update for Sage, but does supply features some
people have been waiting for, including fast factorisation of unsigned
longs. I also fixed the issues that David Harvey noted in the makefile
and fmpz.c which Sage currently patches.

If you google onelinefactor.pdf you'll get it.

Here it is:
sage: factor(n)
:)
On a more serious note, this sounds like a good candidate for 4.0.2
as well.

You should know that the webpage release date is incorrect.

Why are the files F_mpz_mat* no longer present? sage was applying
patches that built some kind of NTL interface that (still) depends on
those files. With those patches, modified, I can't build this, partly
because
...
NTL-interface.cpp:41:23: error: F_mpz_mat.h: No such file or directory
In file included from NTL-interface.cpp:43:

make: *** [NTL-interface.o] Error 1
Even a vanilla untar and make fails, presumably due to not picking up
GMP and NTL headers. There's a flint-env file that hardcodes various
relevant settings to /home/wbhart and /home/was, am I expected to
source that? A README or INSTALL file -- even if it's very brief --
would be nice.

of reference to those files. They aren't used.

unpatched. These files shouldn't be there, so I removed any reference
to them from NTL-interface.cpp, etc.
Let me know if there are any further issues with this.

The introduced -fopenmp command in LIBS makes this fail at runtime on
sage.math. Remove that command and it works fine. openmp is not used
anywhere, can this go?
It would be really nice if there was a make target that built the
library with the NTL interface included, or a separate NTL target that
built a separate additional NTL library and the tests. Then you would
remember to test the NTL interface and sage wouldn't have to patch the
makefile. Is that doable?
