Nope, I don't see this happening until I a) valgrind the new doctests b) build it on Cygwin, Solaris, Linux/Itanium and G4/G5 on OSX 10.4 and 10.5 and have all doctests pass and the doctests pass. ghmm has taught me that just because it mostly works and there is only a couple allegedly easy bugs to fix a patch like that can still hold up a release for an extended amount of time (2 weeks in 3.1.2 in my guesstimation). And those bugs in ghmm on Itanium are still not fixed, but we did disable doctests globally in those two files in order to make the doctests pass. 3.1.3 is supposed to be out soon, i.e. before the SD 10 coding sprint, and I am not willing to take the risk of pynac's integration bundle. > Thanks, > > Jason Cheers, Michael --~--~-~--~~~---~--~~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~--~~~~--~~--~--~---

Yep, it is certainly the highest priority ticket for 3.2 and 3.1.3 has
unfortunately delayed longer than planned. I plan to do 3.1.3.rc0
tonight and unless something major happens it should be very close to
final. Then we can open 3.2 during the coding sprint at SD 10 here at
Loria.

The issue right now with the notebook on Solaris is that the key generation takes forever due to sucky entropy caused by RANDMAX issues. I can fix that, but I want to make sure that I do not open a gaping security issue.

I think that issue is easy to fix (RAND_MAX related probably), but the even shorter way to profile here is either using VTune (which is proprietary) or Systemtap (which is free).

"which readline" shows nothing! Well, your likely have to install the readline development package from your package manager. You can also likely copy the readline headers from Sage into /usr/include and then R should compile, but that is not very clean.

Yes, for the convert command this should be used. Once we do that this should also stop the annoying "convert not found" crap printed when doctesting. That still does not resolve the issue for Emacs that is launched due to hg executing EDITOR. > William Cheers, Michael --~--~-~--~~~---~--~~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~--~~~~--~~--~--~---

The solution is: * create a convert script in $SAGE_LOCAL/bin * set DYLD_LIBRARY_PATH to SAGE_ORIG_DYLD_LIBRARY_PATH * call convert with an absolute path (use "which convert" from outside Sage) and pass on all parameters (i.e. /use/local/foo/convert "$@") We should probably do that automatically on OSX for convert, emacs and the other usual suspects.

Hi, the VMware application of Sage on Windows stores the worksheets just like the native OSX and Linux versions in $HOME/.sage. Unfortunately it is not possible yet to do a one step download and re-upload of all worksheets, but that is an open issue to be fixed in the future. So you can either down and upload them one by one (tedious for obvious reasons) or use a tool like WinSCP to log into the running VMware seesion and copy the .sage directory from the old to the new image. Let us know if you have any more trouble.

If you get the patch applied and so on do the following: export SAGE_PEXPECT_LOG=yes, then start sage from that console, do some examples that break. Then check out $DOT_SAGE/pexpect_logs/ (that is usually $HOME/.sage/pexpect_logs/) and send us the logs. That will likely allow us to pinpoint what is going wrong. If you do not want to or cannot do the patching just wait for 3.1.3 and it will have everything build in.

The output from top as is is useless since there is no information to gain. One would at least need PPID and the command line option used to start the python jobs.

Yes, any account on a Notebook server hands the user a shell, so you
either trust them or you secure the server itself.

There are a couple possibilities:
a) a chroot jail
b) a VMWare image (or some other kind of virtualization)
c) SELinux, potentially in combination with (a)
None of the above is simple and securing a server so that it runs with
SELinux is difficult. There is no documentation on how to do this yet.
I would favor (b), frequent backups of the Sage notebook data and some
intrusion detection system in the notebook in addition to keeping
kernel and all the other components current to avoid break ins. Since
you are running a VMware image it is easily resettable and the
likelyhood of breaking out of the VMWare image is relatively small. So
should you have somebody break into your box it is much easier to
reset an image than the server. If you come up with something we would
definitely like to hear about it.

Thanks. Numpy is complaining about a missing math module, but I think that is more likely caused by the libpng.dylib disaster than anything else. I just checked the python.spkg and we are running "make install" with parallel make, which I would guess is not a good idea :) The ticket for that issue is #4174 and there should be an spkg shortly. > Justin > Cheers, Michael > -- > Justin C.

I am playing with libpng-1.2.32 since that is the latest release and
also has a boatload of security updates since the lowly 1.2.22 that we
ship. Hopefully this will resolve the symbol missing issues. I am
testing 3.1.3.alpha0 on OSX 10.5 to see if I can hit any of those
problems.

IIRC surf does depend on some Java binary code shipped with Singular
and we have removed it. I am also pretty sure surf is broken when used
via the notebook server.

Check your home directory for any file with an accent or Umlaut and you likely found the culprit you need to rename. This has been open on the clisp end forever and has never been fixed.

To do so edit $SAGE_ROOT/local/ lib/python2.5/config/Makefile and change # Compiler options OPT=-DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes to # Compiler options OPT=-DNDEBUG -g -fwrapv -O0 -Wall -Wstrict-prototypes Maybe that will help. Then do a "sage -ba" to rebuild the whole Sage library If that still does not help you can also build Python with "-O0", but we can do that later.

Sage 3.1.2 will have the fixes so we no longer end up using Apple's
IOKit. This caused a bunch of issues with libpng.dylib similar to the
above. There is an spkg for libjpeg, but it is not merged yet. Once
that is merged the above problem will go away.

Nope, it isn't. I have a bunch of fixes to build Sage with gcc 4.4.CVS, but since that compiler is at Stage 3 they will not be in 3.1.2.

You need a little wrapper script or clisp as well as clisp.bin like #!/bin/sh "$SAGE_ROOT/local/bin/clisp.bin" -B "$SAGE_ROOT/local/lib/clisp-2.46" "$@" and adjust the path and binary name for your install. You can also change the maxima.spkg to use clisp instead of clisp.bin as a binary name. > Any thoughts how to fix this problem would be highly > appreciated. Below are the last 50 lines of install.log: In so many words: clisp sucks and we will hopefully switch to ecl in the next (3.2) release.

And building the GNU Ada compiler from sources is a giant pain unless you have the GNU Ada compiler to bootstrap. I did build some phcpack binaries for x86-64 Linux and it has a tendency to segfault when run on say Debian if the binary was build on a FC8 box and vice versa. I mainly wanted an Itanium binary, but cross compiling the ada toolchain was just plainly not worth it for it. So in conclusion: great code if you can use a binary that works, if you need to build from sources it plainly sucks. The lesson learned here is not to use exotic languages since the (alleged) benefit from using Ada is far outweight by the fact that the practicality of building the code :) > William Stein Cheers, Michael > Associate Professor of Mathematics > University of Washingtonhttp://wstein.org --~--~-~--~~~---~--~~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~--~~~~--~~--~--~---

No one for 64 bits in sight yet since we plan to fix a couple bugs first before switching over to optionally 64 bit on Solaris. Once 32 bits work I expect very little trouble for the 64 bit port.

In case of the vandalism you suggested Sage had something to do with: * 193.53.87.109 is from an Indian IP space * 78.157.143.233 is from a Latvian IP space and I doubt anybody needs Sage to write a Spam bot in Python - if it even were written in Python.

Sun's gcc version as well as the one from Blastwave are pretty bad IMHO to build Sage. The main issue is that they are usually build to use Sun's ld and as and many packages in Sage detect gld and gas and/ or have GNUisms, so things tend to blow up. Sun's build of the GNU binutils is also quite buggy and those bugs prevent Sage from building. > If anyone has built Sage on Solaris, can they advise what compiler > version, as well as any other information which might be useful. I build my own custom toolchain (at least gcc, binutils and gmake) to build Sage. But even that custom build chain does not build Sage out of the box; I have about 10 fixes I need to merge back into Sage to get close for it to work in 32 bit mode on Solaris 10 out of the box for now. The medium term plan is to have a custom toolchain for Sage on Solaris build out of the box before Sage since the system compilers on Solaris will always give trouble.

Bingo, pbuild is broken in Sage 3.0.4. Please apply the patch from
http://trac.sagemath.org/sage_trac/ticket/3614
to $SAGE_ROOT/data/extcode, i.e. download the patch, i.e.
wget
http://trac.sagemath.org/sage_trac/attachment/ticket/3614/trac_3614.patch?format=raw
then run
hg import trac_3614.patch?format=raw
in $SAGE_ROOT/data/extcode
After restart the build with "make" and everything should finish from
there.

We upgraded clisp in 3.0.4 and so far we did not test on Linux PPC. But we will be upgrading to ecls in August, depending on Maxima merging the ecl branch into Maxime 5.16.x.

Thanks. I found the problem, but so far I am still in the dark for the
cause since this is one of those things which cannot happen, but
apparently it does in your case:
My 3.0.4 build:
gcc -fno-strict-aliasing -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-
prototypes -fPIC -I/scratch/mabshoff/release-cycle/sage-3.0.4-vg/local/
lib/python2.5/site-packages/numpy/core/include/numpy -I/scrat
ch/mabshoff/release-cycle/sage-3.0.4-vg/local//include -I/scratch/
mabshoff/release-cycle/sage-3.0.4-vg/local//include/csage -I/scratch/
mabshoff/release-cycle/sage-3.0.4-vg/devel//sage/sage/ext -I/
scratch/mabshoff/release-cycle/sage-3.0.4-vg/local/include/python2.5 -
c sage/finance/time_series.c -o build/temp.linux-x86_64-2.5/sage/
finance/time_series.o -w -w
Your build of the time_series extension:
gcc -g -c -fPIC -O3 -fwrapv -fno-strict-aliasing devel/sage/sage/
finance/time_series.c -DNDEBUG -I/var/abs/local/sage/src/sage-3.0.4/
local/include -I/var/abs/local/sage/src/sage-3.0.4/local/incl
ude/csage -I/var/abs/local/sage/src/sage-3.0.4/devel/sage/sage/ext -
I/var/abs/local/sage/src/sage-3.0.4/local/include/python2.5 -o /var/
abs/local/sage/src/sage-3.0.4/devel/sage/build/temp/sage/
finance/time_series.o
Notice the missing numpy include. The build options for the
time_series extension are in $SAGE_ROOT/devel/sage/setup.py:
time_series = Extension('sage.finance.time_series',['sage/finance/
time_series.pyx'],
include_dirs=debian_include_dirs + [SAGE_ROOT
+'/local/lib/python2.5/site-packages/numpy/core/include/numpy'])
Can you check what exactly it says there? This seems to be a new
install, but did you build in a new directory or over an old version
of Sage?
What does "hg status" in $SAGE_ROOT/devel/sage say? You might have to
"source local/bin/sage-env" from $SAGE_ROOT to have hg in $PATH.

Hi Thierry, it is generally *not* recommended to install all or even many optional/ experimental spkgs unless you need them. In detail to your list: polymake: tracked at http://trac.sagemath.org/sage_trac/ticket/3640 - I will fix this today once and for all. dvipng: install from the distribution. The dependencies are insane to build this from source and it should be deleted to moved to experimental. jmol-11.5.2-src-v2: this is the source version of a binary spkg already installed. No need to install it. hermes: *never* even heard of it, too lazy to google it now :). fricas: It is a known problem that the current FriCAS.spkg builds with gcl since our clisp is either compiled with the wrong options or broken. We have a ticket for that somewhere. But I would recommend you build the latest FriCAS release (which is more current than the spkg anyway). As long as it is in $PATH Sage should be able to pick it up. I would also suggest we move the FriCAS.spkg to experimental until the lisp issues are sorted out. We will start shipping ecl with the August Maxima release (5.16.x) assuming the ecl branch gets merged. Cheers, Michael > > -- > > Thierry Dumont. Institut Camille Jordan -- Mathematiques-- > Univ.

[sage-support] Re: Sage 3.0.4 Fails with "ImportError"
Hi Robert, I looked at your build log you send me off list and lcalc failed to build. I suspect it is due to some CFLAG option we set, namely using "- static-libgcc". According to the log this was added a while back, but I see no reason to add it at all. Can you take the spkg at http://sage.math.washington.edu/home/mabshoff/lcalc-20080205.p2.spkg and put it into $SAGE_ROOT/spkg/standard and run "make" again from $SAGE_ROOT since you did not finish building Sage.

The goal is to specify say some finite element and then have logic to produce C or Fortran code that can be dumped to file and then copy and pasted into someones C or Fortran code without the need to depend on Sage.
