Hello folks, most 3.4.2 binaries are up on sagemath.org and being mirrored out. From the usual suspects some are still missing, i.e. * Fedora Core 10 32 bit * Atom * RHEL 5.2/SLES 10 Itanium * OSX 10.4 Intel Most of the missing binaries will show up in the next 24 hours. We also have some new ones that are not regularly posted: * Solaris 10/x86 (two trivial failures for long doctests) * Solaris 10/sparc (two trivial failures for long doctests) * OSX 10.5 MacIntel 64 bit (passes all long doctests) Those three above have selected fixes from 4.0.a0 and all three binaries should work and pass all doctests out of the box once Sage 4.0 is out early next week.

On May 4, 2:16 am, chand sarat chandcsa...@gmail.com wrote: Dear All, Hi, It is a fact that for a number of scientific packages, Ubuntu does offer fairly outdated packages: 1. Current Sage package: 3.4.1 and the version offered by Ubuntu 9.04 is Sage 3.0.5. Help is on the way: Debian experimental should soon have Sage 4.0.x - see http://wiki.sagemath.org/debian/sage-4.0.x-in-experimental - that won't help Ubuntu 9.04, but I seriously doubt that either Debian or Ubuntu will ever ship the current stable Sage release. We provide binaries, but not debs for various Debian and Ubuntu releases. But I don't see them being integrated in any clean way into the system, i.e. if we provide Ubuntu deb packages they would install into /opt and not use anything from the system. 2. Current Maxima package: 5.18. and the version offered by Ubuntu 9.04 is Maxima 5.13. This isn't the problem of the Sage project and out of scope. 3. Current Texlive package: 2008 and the version offered by Ubuntu 9.04 is Texlive 2007. That is not our concern and has nothing to do with Sage. It seems to be that Canonical's key focus is to provide a set of up to date packages including office packages (openoffice.org), web browser (firefox) etc. while the up-tpdateness of scientific packages are more volunteer dependent. Well, complain to the Ubuntu people :) In the case of Maxima, Istvan Blahota (http://zeus.nyf.hu/~blahota/maxima/jaunty/) has compiled deb packages for Ubuntu 9.04 conforming to the the latest version of Maxima namely 5.18 for both i386 and amd64 architectures; moreover each of them has been compiled with both CLisp and SBCL. It would be great if someone from the Sage team can do the same for Ubuntu i.e. provide deb packages of the latest version of Sage for both i386 and amd64 architectures. I would suggest you complain in the Maxima group to have them take a stake into packaging current Maxima releases for Debian/Ubuntu. AFAIK the Maxima maintainer for Debian isn't exactly underworked, so I am sure he could use some help. Yours, C.

AFAIK the Maxima maintainer for Debian isn't exactly underworked, so I am sure he could use some help. Hello, not related to Sage, but if I remember correctly, newer Maxima is in Debian Sid (compiled with GCL). This Sid version is slower than 5.13 (with GCL also). Do you have any idea why that is and how much slowdown there is? What specifically is slower? Might this be due to the rather small RAM footprint of the server? The reason Sage did not upgrade to Maxima 5.17.x was due to various new problems that cropped up in that Maxima release. I am not sure how 5.18.x fares, but AFAIK the current ecl release has test suite failures due to disagreements about float behavior (according to the emails I read on the Maxima list), but my memory could be wrong here. In either case, if Maxima 5.18.1 does not pass its test suite with the current ecl release Sage will not upgrade. New version can be compiled and installed using checkinstall also from sources easily (tested on debian with cmuml and clisp - again much slower than maxima 5.13 - tested on a very small server with 125 MB RAM) You can install this Sid package also into Lenny. see alsohttp://packages.debian.org/cs/sid/i386/maxima Robert Cheers, Michael --~--~-~--~~~---~--~~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~--~~~~--~~--~--~---

It won't make much of a difference size wise and for debugging problems like this is is rather helpful since otherwise we are otherwise poking around in the dark.

This might exceed the length of the screen, so there might be another prompt to continue. Copy and paste the backtrace (I assume only the first 20 lines will be of interest, but to be safe take the whole first page). Then hit enter until you get a prompt again. enter disassemble $pc+32,$pc-32 at the gdb prompt and copy and paste the output.

[sage-support] Re: memory leak?
FYI: Simon's patch doesn't make any difference for the amount of memory used for sage: while p2^20: : p=next_prime(p) : g=FindGroupOrder(p,11) : In both cases about 2046MB more were used after the loop :(. Simon: Run init_mem=get_memory_usage() before you do anything, run the computation and then once you are done run get_memory_usage()-init_mem and compare the different to before the patch. I assume Alex's script he attached to the ticket does something similar. It might be a good idea to create some constant at the very end of all.py that sets the initial amount of memory used so it is trivially invokable because once you have hit a leak it is too late anyway :( Not that the patch will fix some other issues, but the picture seems to be more complex. I am sure we will get to the bottom of it :).

Note however that running just a loop where the polynomial ring is created does benefit from the change in Simon's patch: doing it for p up to 2^17, this used to eat up 272MB, and after the patch it's only taking 10MB. Cool, that matches with my experience, so it is part of the solution to get the initial problem fixed. I did experience the same phenomenon that Michael is describing when running loops where elliptic curves (or even just plane curves) are created. The patch seems to have no effect on those loops. Yep. I would not be surprised if Simon's patch just exposes the next problem - oh well, fixing leaks is an eternal game of whack-a-mole ;). I am all in favor on adding some looping tests that measure memory consumption and that would fail if repeated runs start to leak memory (again) once they are fixed.

Gonzalo had the exact same problem about GAP not starting up when he was playing around with a Debian chroot env and it turned out that he needed to mount devpts. According to the output above that (pseudo) filesystem is not mounted, so before trying anything else I would recommend to mount it. The kernel might or might not support it out of the box (since it is a Debian kernel it should). devpts should be mounted by udev it seems per default, but check out http://linux.derkeiler.com/Newsgroups/comp.os.linux.setup/2005-03/0473.html on how to mount it. If this turns out to the cause it seems well worth an entry in the FAQ as well as README.txt since this is a rather obscure problem. Even adding a check in Sage somewhere to verify that the devpts is mounted on startup of Sage might be worth it. william Cheers, Michael --~--~-~--~~~---~--~~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~--~~~~--~~--~--~---

Any recent clisp source release is incredibly easy to miscompile and we are building it with -O0 with any compiler to maximize our chances to make it work. But no clisp release since 2.41 has ever even build on the build farm or SkyNet, much less various OSX releases or Solaris (at least not with anything beyond gcc 4.x). That is the reason we are switching and numerous other projects have prevented me from doing the clisp - ecl switch, but finally its time has come since that is the only way to support Solaris properly. cs Cheers, Michael --~--~-~--~~~---~--~~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~--~~~~--~~--~--~---

It will also not use the readline-off mode we hacked into clisp 2.47, but if you never saw any Maxima hangs it should not matter to you too. You must also force a rebuild of the Maxima.spkg (via ./sage -f ../maxima- x.y.z.spkg after rebuilding clisp to make it use that version of clisp you just build without trouble). Note that the above change will likely be overwritten by updated Maxima and ecl.spkgs in Sage 4.0, but not 3.4.2.

When I returned home this evening the process and the whole system seemed to be frozen as if by memory overload.

So I can't even say that the compilation literally crashed or froze, only that I am a little too stupid to let it do it's job. Actually it just takes a while to build LinBox and its Sage extension if you have little, i.e. less than 300 or so MB memory available.

If so, this would be really cool. If not, any plans to have this feature in the future in sage? It would be like running a applet inside the browser in a way. Yes, but without proper input filtering, etc, this would be a rather insecure setup. I am sure that such input filtering could be added for standard types, i.e. integers, rationals and so on as well as strings, but AFAIK no one has written any code in that direction yet.

But, in the directory I have a dmg file and one subdirectory sage-3.4-i386-Darwin, which just looks like another copy of SAGE_ROOT. I don't see any clickable Mac OS X app anywhere, including in the disk image from the dmg file. What am I missing? I believe there were some bugs/kinks in the clickable app, so we still aren't making it by default when one does sage -bdist. William Run SAGE_APP_BUNDLE=yes; export SAGE_APP_BUNDLE before -bdisting and there App bundle will be created. As William mentioned due to bugs this is not done per default at the moment.

There is a G4 notebook in the Sage lab in Seattle, but it only has 256 MB RAM, so building Sage on it takes forever. If we could upgrade the memory it would be useful enough to build 10.4 PPC G4 binaries. - kcrisman Cheers, Michael --~--~-~--~~~---~--~~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~--~~~~--~~--~--~---

Since Sage has a complete Python installation in it (accessible through sage -python), I have been able to install the few Python packages I needed directly into Sage (e.g., PyCUDA) by using sage -python instead of python in the installation instructions and explicitly giving the Sage root directory. If you give the names of the packages you're looking to use with Sage, I (or we) can try it on my machine. If you want to install packages into Sage's Python run ./sage -sh before using the 'normal' install mechanism to install the python package, i.e. python setup.py install will then install into Sage's python. In theory you should be able to set PYTHONPATH and pull in packages from another Python install, but in some cases this causes trouble when you have different API releases or a python build with different options, etc. In general it is possible of you know what you are doing, but there are plenty if problems you might run into.

To be precise, I get the following type of complaint: 'You cannot copy some of these items to the destination because their names are the same as the names of items on the destination, except for the case of some characters.' The item it is referring to is in local/bin, namely singular vs. Singular vs. Singular-3-0-4 vs. TSingular. I don't tend to use Singular too much, so I'm tempted to just delete the file it's complaining about (singular, lower-case, whose total content is #!/ bin/sh Singular-3-0-4 $*), but this seems very odd to me; I've never seen a Mac complain about this sort of capitalization thing before. I wouldn't delete anything like that. It will likely break something for the Sage - Singular interface. Any ideas?
