sage-4.3

[William Stein]

Hi,

Merry Christmas! I have released sage-4.3, which is a massive
release with 230 tickets closed, which you can see listed here:

http://trac.sagemath.org/sage_trac/query?status=closed&group=component&max=230&order=priority&col=id&col=summary&col=owner&col=type&col=priority&col=component&col=work_issues&milestone=sage-4.3

You can download the source code here:

http://sage.math.washington.edu/sage/src/

You should be able to upgrade with

sage -upgrade http://sagemath.org/packages/

I'm posting binaries for many systems (except Windows) here right now
(this will take some hours to finish):

http://sage.math.washington.edu/home/wstein/binaries

(Note that I found an OS X 10.5 build machine -- in Mike Rubinstein's
office :-) -- so this time we don't have to worry about that.)

Please use one of the mirrors for faster downloading.
these are already in sync:

hi, i just want to tell you that the website is now set to 4.3. here
are a couple of things:

* the network is still slow, so syncing the mirrors will take days.

* i tried to build it on my intel n270 netbook, but R didn't respect
the sage_fortran variables and it's the same problem as in earlier
versions. setting env variables worked with 4.2.1 though... maybe
someone else has more luck?

* there are now 4 lzma compressed archives for ubuntu 9.10 and fedora
12. both distributions depend on lzma (resp. xz which is compatible)
because they started to use it for compressing deb and rpm archives.
that's why lzma support is a hard dependency and therefore i gave it a
try. let's hope nobody is confused, readme+download guide is updated.

* i copied 18 binaries, just windows and atom n270 missing i think.

* minh told me that he is working on the sphinx-pdf problem that
occurs when building mip.rst .. once this is resolved he will take
care of the documentation.

[Rob Beezer]

Passed all tests (-t -long) on Kubuntu 9.10 on 64-bit Core Duo.

Thanks for the Christmas present! Nothing quite like shopping on
Christmas Eve.

thx!

What I also forgot in the list above, the changelog is (once again)
missing ...

I feel like mhansen had posted the script he uses to generate (most)
of the information for them on a Trac ticket, but I can't remember
which one it was. Minh, can you take this one?

- kcrisman

[kcrisman]

All worked well on MacIntel 10.5, but for the fact that it never
*formally* finished the build and returned to a prompt:

To install gap, gp, singular, etc., scripts
in a standard bin directory, start sage and
type something like
sage: install_scripts('/usr/local/bin')
at the Sage command prompt.

Sage build/upgrade complete!

... and then I didn't get a prompt. So I had to manually do this:

^Cmake: *** [all] Error 130

I don't know if anyone else has encountered this.

[Mike Hansen]

Here is the info for Sage 4.3. I've attached the little (rough)
script that generates this. It is called like
"./generate_release_notes.py sage-4.3"

Thanks, that is super helpful for the future!

Is it possible to add a thing on Trac on "merged in" to opt for Sage
or SageNB? That would assist in making this more accurate and easy to
do in the long run, as well as provide more detail for those looking
in the future to see what is going on in Sage vs. SageNB development.
Just a thought.

To Minh:

If possible, make sure to continue finding out what tickets under
"other tickets" below are really SageNB tickets and report them in a
separate category from other "other" tickets, and give reasons why
those other "other" tickets were closed - I feel this is important to
document other than on Trac alone.

Probably the latter is the best idea, and it would be good for release
managers to remind the SageNB package administrators to do this :) I
think something separate at this point would make a higher hurdle for
Sage people to also contribute to SageNB. Not to mention annoying in
various other ways, I'm sure.

My second try worked. I started fresh and set the variables right from
the beginning. Just two doctests (plot and ell_rational_field) had
timeouts. So, we have an atom build, too.

Yippee!

What an exquisite Christmas gift for the Sage-Combinat team :-)
We are glad not to have to worry about this pile of patches anymore!

Cheers,
Nicolas

PS: Minh, let me know if you need help for the category/combinat part
of the release tour

I am probably the original culprit for that one :-) Could someone
please fix it? Thanks!

Thanks!

Maybe at some point we should have a separation "main author(s)" /
"contributor(s)", but that's good for now.

I haven't seen these reported:

$ \time ./sage -tp 16 devel/sage
...
The following tests failed:

sage -t devel/sage/sage/symbolic/expression.pyx # 6 doctests failed
sage -t devel/sage/sage/numerical/optimize.py # 6 doctests failed
sage -t devel/sage/sage/interfaces/r.py # 3 doctests failed
----------------------------------------------------------------------
Total time for all tests: 458.2 seconds

(detailed errors below)

This is a new machine with 2 * quad core xeon (nehalem) and plenty of ram.

I'm also getting ocasional errors (in random files) which claim:

"""
A mysterious error (perhaps a memory error?) occurred, which may have
crashed doctest.
"""

Is there any other explanation of this rather than a memory error? (dammit!)
