[sage-devel] Fwd: [NumPy] #1525: Numpy is ignoring CFLAGS, which makes a 64-bit build difficult

2010-06-28 Thread Dr. David Kirkby

A two-year old Sage ticket added 64-bit OS X support for Numpy.

http://trac.sagemath.org/sage_trac/ticket/3186

But the method used was a bit brain-dead. A script with a hard-coded path to gcc 
was used, which had the -m64 flag. That was then copied and used as compiler.


I've removed that file gcc_fake, but created a similar one dynamically, so the 
path of gcc does not have to be /usr/bin/gcc. The package is here


http://boxen.math.washington.edu/home/kirkby/patches/numpy-1.3.0.p4.spkg
awaiting review
http://trac.sagemath.org/sage_trac/ticket/8086

But this is really a hack, so the issue has now been reported upstream to the 
Numpy developers via their bug-tracking system. Hopefully they can fix it so 
CFLAGS gets inherited properly.

 I am trying to get Numpy to build as a 64-bit executable, as part of a
 64-bit port of Sage to !OpenSolaris. But despite adding the compiler
 option -m64 (which generates 64-bit objects) to CFLAGS, Numpy ignores this
 so GCC generates an error.

 The same issue has been known in Sage for a long time affecting OS X
 systems where building 32-bit objects is the default, so one needed the
 -m64 compiler flag to generate the 64-bit code.

 {{{
  wrong ELF class: ELFCLASS64
 }}}

 which is typical of when a program is expecting to find a 32-bit object,
 but finds a 64-bit one.

[sage-devel] Anyone want to help port Sage to Solaris/OpenSolairs 64-bit ??

2010-06-28 Thread Dr. David Kirkby
Following Roberts huge effort to get a lot of .spkg updates into 
sage-4.5.0.alpha0, a 64-bit build of Sage on both Solaris 10 SPARC and 
OpenSolaris x64 does not look to be a distant dream any more. I think it will be 
close race between a Cygwin port and 64-bit Solaris or OpenSolaris port.


There are still however 5 or 6 problems with a Solaris build, so any help would 
be appreciated.


One or two problems might be specific to Solaris 10 SPARC or specific to 
OpenSolaris x64, but most of the problems appear on all 64-bit versions of Solaris.


There are two ways to attack this port.

1) Install OpenSolaris, which is a free download, as a virtual machine. One 
problem with this can be that if your BIOS on your PC is crippled, you can only 
install 32-bit operating systems as virtual machines. This is the case with my 
Sony Vaio.



2) Use 't2' and build Sage on there in 64-bit mode. Now the parallel building of 
packages is working, building on 't2' is nowhere near the pain it used to be, 
though it is still not exactly fast.


The only changes for those used to building Sage on t2 are

$ export SAGE64=yes
$ export 
SAGE_FORTRAN_LIB=/usr/local/gcc-4.4.1-sun-linker/lib/sparcv9/libgfortran.so


There's a list of the issues on a 'metaticket'

http://trac.sagemath.org/sage_trac/ticket/9026

Most of the issues are resolved in sage-4.5.0.alpha0. The few remaining are:

1) Pynac - http://trac.sagemath.org/sage_trac/ticket/9026
Awaiting review.
http://boxen.math.washington.edu/home/kirkby/patches/pynac-0.2.0.p4.spkg

2) Libfpll
http://trac.sagemath.org/sage_trac/ticket/7864
awaiting review
http://boxen.math.washington.edu/home/kirkby/patches/libfplll-3.0.12.p1.spkg

3) Numpy
http://trac.sagemath.org/sage_trac/ticket/8086
awaiting review
http://boxen.math.washington.edu/home/kirkby/patches/numpy-1.3.0.p4.spkg

4) R.
http://trac.sagemath.org/sage_trac/ticket/9040
This is potentially problematic, as R does not apparently build with gcc on x86 
versions of Solaris, though it does with Sun Studio


I'm hoping to get the help of Dennis Clarke of Blastwave on this one. We don't 
really want to make have two compilers a prerequisite for building Sage.


But since R is only called via the command line, and not a library, we can just 
forget R for a minute.


5) Maxima
http://trac.sagemath.org/sage_trac/ticket/9099

6) Sage library.
This patch (awaiting review) allows c_lib to build
http://trac.sagemath.org/sage_trac/ticket/9097

but then things go wrong and I can't work out where the compiler flags are 
coming from. Can someone take a look at this, and tell me what's up


http://groups.google.co.uk/group/sage-devel/browse_thread/thread/14155a7f42d4df7a#


7) Scipy installs, but I'm very suspicious it is not a full 64-bit install.
http://trac.sagemath.org/sage_trac/ticket/9100
This is because some of the object files created are 32-bit, though the final 
build is fully 64-bit. Something is wrong there.


8) Linbox
http://trac.sagemath.org/sage_trac/ticket/9101
This is problematic on Solaris 10 SPARC, but works fine on OpenSolaris. As such, 
that can only be solved with the aid of 't2' or similar SPARC based system.


9) Singular
http://trac.sagemath.org/sage_trac/ticket/9033

I find the libsingular build will not complete, though the other bits in the 
Singular package do. One can just comment out the line that builds libsingular, 
though clearly that is not ideal.


For more detailed discussions, we should take this to sage-solaris, or drop me 
private emails, But I'd like to get a bit of feedback here. See who is willing 
to do what. I think any one of many people probably here probably know how to 
solve the issue with the Sage library.


http://groups.google.co.uk/group/sage-devel/browse_thread/thread/14155a7f42d4df7a#

Somehow it needs to be told to add the -m64 flag, but I don't know how.

   * OpenSolaris on SPARC processors.
   * OpenSolaris on x86 processors.
   * HP-UX on PA-RISC processors.

the default is to build 32-bit objects, but 64-bit objects can be created if
needed. This is usually done via adding the -m64 flag when compiling with GCC or
SunStudio, though the flag will be different with HP's compiler.

Numpy is used as part of Sage, but it would appear that adding -m64 to CFLAGS
will not work. A comment in the script used to build numpy shows:


First: Is Python built using -m64? If not, is there a reason that NumPy
in 64 bit and load it into 32 bit Python work? If Python is built with
-m64 I'd expect NumPy to pick it up automatically as it queries Python
for the build flags to use...


Yes, Python is built 64-bit, using the -m64 option.


# numpy's distutils is buggy and runs a conftest without
# taking CFLAGS into account. With 64 bit OSX this results
# in *boom*

it then goes on to copy a file called gcc_fake, which is basically a script
which gets renamed to gcc, but includes the -m64 flag.

We are using numpy-1.3.0.

Is this a known bug? If not, can I submit it to a bug database? Better still,
does anyone have a patch to resolve it - I hate the idea of making


Until somebody who really knows an answer chimes in;

AFAIK this is a "feature" in distutils itself, so it affects most Python
software. (Setting CFLAGS overwrites the necesarry CFLAGS settings, like
-fPIC and -fno-strict-aliasing, that is queried from Python). Try
setting "OPT" instead?

Dag Sverre


OPT has -m64 in it.

This is the bit that shows how Python is built on Solaris (uname=SunOS). SAGE64 
will be set to "yes" for a 64-bit build.


OPT="-g -O3 -m64 -Wall -Wstrict-prototypes"; export OPT
./configure $EXTRAFLAGS --prefix="$SAGE_LOCAL"  \
--enable-unicode=ucs4 --with-gcc="gcc -m64"


Many other parts of Sage seem to inherit the flags ok from Python, but not 
numpy.

It is not a Solaris specific issue, as the same issue results on OS X.

Thank you Mike. We don't have 'nosetests' as a part of Sage, but it should be 
possible to write a script which just executes the first two lines.


I'll add that to Sage so we can run the matplotlib test suite.

Is there such a test suite, and if so how does one invoke it?

Subject: William, Write a "Sagemath" Book for Packt Publishing!
To: wst...@gmail.com


Hi William,

I am an author recruiter at Packt Publishing (www.packtpub.com). We
publish computer-related books on a wide variety of IT topics.

We are planning to publish a new book on Sagemath. While trying to
look out for potential authors to write this book, I came across one
of your blog and website which shows your expertise in Sagemath. This
gives me an impression that you could be a potential author for this
book.

Details of the Book:

Title: Sagemath Beginners Guide
It is planned to be a 300 page book targeted at Scientists,
Mathematicians and Engineers who want a practical introduction to
Sage.

Prerequisite for readers: No knowledge of Sage is expected, basic
knowledge of other programming languages will be an advantage.

To give you an idea about the way things works at Packt:

- The editorial team at Packt works with the author through out the project.
- We pay a royalty of 16% and an advance against it.
- The marketing team at Packt ensures that the book is well promoted.
- In its ongoing commitment to OpenSource, Packt donates a percentage
of revenue generated by the book to the OpenSource project on which it
is based. We have donated more than 150 000 dollars to various
OpenSource projects since inception in 2004.

Could you please let me know if you find it interesting to write this book?

Regards,
Mary.

[sage-devel] question about _sig_on _sig_off in cython code

2010-06-28 Thread luisfe
Hi,

I have found an unhandled SIGFPE in number_field_element_quadratic as
explained in ticket http://trac.sagemath.org/sage_trac/ticket/9357

Basically, sage does not check if a quadratic algebraic number is zero
when trying to invert it.

I added a trivial patch that checks if the zero element is being
inverted to rise a ZeroDivisionError. However, the error message
before the crash suggests that the compiled code is not properly
wrapped with _sig_on _sig_off.

In this example even if one adds this wrapper the zero check is
advisable, since _sing_on would rise a RuntimeError instead a
ZeroDivisionError, so it seems that the zero check is enough in this
case. On the other hand would the _sig_on stuff made the code more
robust? What is the way to proceed in this cases?

Thanks,

Luis

[sage-devel] Sage 4.4.4 doctest failure on Mac PPC

2010-06-28 Thread kcrisman
I know there are not tons of PPC users still on these lists, but I
wanted to ask whether they had seen something weird when testing sage/
interfaces/maxima.py.  Namely, there is a guaranteed timeout (even
with SAGE_TIMEOUT=1)!  Previously I traced this to the functions
which create the tab-completion list for maxima.[tab], and I have no
reason to believe this isn't still the problem.

Georg, anyone with access to the Skynet PPC computer (varro?)... any
ideas?  Have you seen this?

2010-06-28 Thread Bill Hart
Even if it is a form letter, I don't think Packt is a scam of any
kind.

They appear to be a real publisher. They focus on IT titles. They do
have staff (usually hired from India, but with "impeccable" English)
who work with the author over a series of revisions and through peer
review, typesetting, indexing, etc...

I don't recall seeing any of their publications. But I checked and
some of them get very good reviews online (good authors I guess).

As with all such things, beware you are dealing with the real people
and not some phoney. I see the links in the form letter don't direct
to the websites they say they do, but instead go via google. Not sure
what's up with that

Maybe it's a form of "click-through" that somehow makes money for someone.  
It's the new economy, all over again.

2010-06-28 Thread Bill Hart
I don't think it is a click-through.

I think this publisher is for real and actually does quite a good job.

Apart from the fact that the cover illustrations have nothing at all
to do with the content, their books seem well-written. They publish a
lot of titles and they offer them much cheaper if you buy them as E-
books. They ship lots of places if you want a physical copy. They also
offer a single chapter from each book for evaluation before you
purchase.

They also do seem to add value to the publication after the author is
done with it.

It is definitely publication on a budget, but their prices seem to
reflect that, and Sage does seem to be something they would definitely
want to publish a book on. If I was an expert Sage user, had more
time, etc, etc. I'd definitely take this seriously.

Bill.

[sage-devel] Re: Multivariate polynomial multiplication

2010-06-28 Thread Bill Hart
I implemented the algorithm for multivariate poly multn. But it is in
flint2, which won't be suitable for inclusion in Sage for some months
(probably the end of the year).

In the mean time, Sage uses Pari or Singular for multivariate poly
multn, if I recall. There's not really anything you can do via flint,
yet. But those options work in the mean time.

Hooking Sage up to use my implementation, even if I pulled it out of
flint2 temporarily, would still be quite some work. At the moment
*all* that is implemented is multiplication. It could be done, but
would require someone quite determined, expert and with quite some
time on their hands.

For the record, any url posted on google groups always redirects
through google when you click on it. Wiliam posted a plain-text

I definitely would not.  In my opinion, the are only two reasonable
options for publishing Sage-related books:

   1. Use an open license and self publish through, e.g., Lulu.The
Sage community can do the hard editing work better than most
publishers.  (Here's I'm talking mainly about Minh Nguyen.)   I think
you'll earn as much money as you would get from Packt, but you get
100% of the profits instead of 18%, so end buyers pay far less (and
get more -- due to the open license).

   2. Publish with a very high quality reputable publisher, e.g.,
Springer, O'Reilly, AMS, Cambridge, Oxford.  They understand the math
world and can advertise.   And they also are starting to understand
"freeness"  Case in point:  http://wstein.org/ent/

Despite the title of #9346, I think that could potentially screw up on any

[sage-devel] rpy2 can try to write outside SAGE_ROOT

2010-06-28 Thread Dr. David Kirkby

I noticed this error message


creating /usr/lib/python2.4/site-packages/rpy2
error: could not create '/usr/lib/python2.4/site-packages/rpy2': Permission 
denied

whilst trying to build R. (See more below if you wish).

The important thing is that it tried to write to directories where the system 
python (/usr/lib) is installed, rather than in the Sage area. If someone tries 
to build Sage as root (and plenty of people are either blissfully unaware of the 
risks, or chose to ignore them), though could end up really screwing their 
system up.


Since I do not  build Sage as root, I just got the error message:

This is a very similar issue to that reported here

http://trac.sagemath.org/sage_trac/ticket/9209

Basically, bits in Sage often "pick up" things like python from outside the Sage 
directory tree, and act on them rather than their own version.

It's not a "PPC specific" issue; I do see this every now and then on
my MacIntel running OS X 10.4.11, so I suspect it's some
incompatibility of the sometimes rather rude way Sage interfaces with
Maxima (via pexpect, using Ctrl-C from time to time) on the one hand,
and on the other hand some system peculiarity/deficiency of OS X 10.4
Tiger. Or maybe the OS X 10.4 system itself is absolutely fine, but
more vulnerable than all the other systems to some "race condition-
like" bug still lurking somewhere in the way Sage incorporates
Maxima.

I remember that once Michael Abshoff had created some mechanism to
make the Sage/Maxima interface (i.e. the pexpect interface in general)
produce verbose output into some log files (via setting an enironment
variable?), but I didn't get around to do any testing in that
direction, and then Michael left the Sage project. And I don't think
it's a problem with the general pexpect interface --- although going
this way might be the only way to go, starting to hunt down the bug.

Georg

Come on William, how can you possibly hold Springer up as the model of
"openness". Where is the tex file? Where is the OSI license text?

Last time I published a paper with Springer, they sent me 50 free
electronic copies of my own damned paper with DRM on them and asked if
I wanted to buy 50 more electronic copies! Every time I publish an
article in a Springer Journal I have to sign a damned copyright
assignment form *and physically fax it to them*. This is bloody
inconvenient. I'm sure Springer is changing, and I am sure their book
publishing division is completely different to their journal
publication section. But really

The whole point of Packt's model is they pay the author a royalty
advance up-front, regardless of the success of the book, then make a
donation to the Open Source project involved (I'm sure it's pretty
small). That possibly gives an author a chance to actually sit down
and write a book that they otherwise wouldn't write. They also add
value to the book by offering publisher expertise throughout the
process, unlikely to be present amongst a bunch of computer
scientists. They *specialise* in Open Source topics, and many very
decent Open Source projects have chosen to publish with them. And
Lulu?

And Packt are reputable. They get reviews on Slashdot, just the same
as O'Reilly.

Bill.

P.S: I don't give a toss whether anyone publishes a Sage book through
Packt or not. This isn't about "religion", though I admit, I don't
"get" Open Source publishing completely. Were we building a community
of publishers, I might, because then it would make sense to say that
we felt we had the expertise to do it better than professional
companies charging exorbitant fees to do the same thing, and keeping
information proprietary.

Yep, google chrome has sucked for me for the past few months. Crashes

To contrast them to Packt well, OK, I can download your Springer
book without paying for it. I suppose it is conceivable Packt wouldn't
allow this, if asked.

On one point, I will agree with you. Packt are not a mathematical
publisher, They focus on IT only. Springer is a specialist in
mathematical publishing. No doubt they also have a *lot* more money to
advertise your book than Packt.

OK. I agree, I was over the top a bit.

I removed my follow up to this, FWIW. I see you mean at least the

The promised binaries are up at
http://boxen.math.washington.edu/home/iandrus/

sage-4.4.4-i386-Darwin.dmg 
has the "old" application--the one that you can make with sage -bdist

sage-deluxe-4.4.4-i386-Darwin.dmg
has the "new" application--it should be nicer, but more experimental.  
Please read the README and give me any feedback you have.

I would have put them both on the same disk image if I could figure out a safe 
way to share SAGE_ROOT without duplicating the data.

Yes, I believe so too, however, the latest version of gcc 4.5.0 causes a

[sage-devel] moinmoin wiki deleting pages

2010-06-28 Thread William Stein
Hi,

Does anybody have a clue why users accidentally randomly delete
Moinmoin pages all the time?  This is constantly happening to people
at Sage Days 22, with all kinds of browsers, networks, etc.

This is very weird.  I couldn't find anything via a fast web search.

We should either upgrade the wiki and see if that fixes the problem,
or move the wiki out of a virtual machine, or failing all that, switch
to media wiki.  Any thoughts?
