[sage-support] Re: Sage on openSUSE 11.2
Hi, 2009/12/4 Nicolás Sirolli nmsiro...@gmail.com: Hello. I'm sorry to bother you (I'm not even certain if it's you I should be writing for this). Are you planning to upload an openSUSE rpm for the 11.2 version soon? Thanks in advance, Nicolás. We currently distribute binaries for openSUSE 11.1 because that version of openSUSE is the version that we have on the build farm. To distribute binaries for openSUSE 11.2 or any newer versions of openSUSE would require an upgrade of the relevant build machines on the build farm. I notice that openSUSE 11.2 was released on November 12th, 2009, which makes it rather new. It would be some time, say, another version or two of Sage, before the build farm is upgraded to contain openSUSE 11.2. There has been reports of problems building Sage on openSUSE 11.2. I think this is in part due to incompatible libreadline libraries. Sage distributes its own libreadline, but openSUSE's version of libreadline has been causing lots of problems for us. Now that openSUSE 11.2 is out, I'm not surprised that the libreadline problem has resurfaced for that version. Many people including myself don't have access to a machine running openSUSE 11.2 so we can't fix the problems with build failures on openSUSE 11.2. Like most open source projects, the Sage project often lacks relevant resources to fix bugs, implement enhancements, and getting Sage to build on as many platforms and CPU architectures as possible. -- Regards Minh Van Nguyen -- 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 URL: http://www.sagemath.org

I have uploaded an updated readline package [1]. Here are the steps to build Sage 4.2.1 with this updated package: 1. Download a source tarball of Sage 4.2.1. Disregard this step if you have already downloaded this tarball. 2. Uncompress the tarball to a directory you have read and write permissions, e.g. your home directory. 3. Remove the readline package that comes with Sage 4.2.1. You can work through this step as follows. Say SAGE_ROOT is the root directory of the uncompressed Sage tarball. From a bash shell, do: cd SAGE_ROOT/spkg/standard rm -f readline-6.0.spkg 4. Download the updated readline package from this sage.math [1] directory. Then copy it over to the directory SAGE_ROOT/spkg/standard. 5. cd to SAGE_ROOT and issue make. This should start Sage's build process to compile Sage with the newer readline package. I make no guarantees that this updated package would work for you because I don't have access to any openSUSE 11.2 machine in order to test. However, please report any problems that you encounter while building Sage with this newer readline package.

[sage-support] losing confidence in Sage notebooks
I have created a pretty large number of worksheets over the last year for courses in pattern recognition and image processing. Unfortunately, I keep having problems with sage versioning. For example, I had renamed worksheets to have a more consistent naming structure, but many of the new names actually have reverted suddenly. Within individual worksheets, I find that sometimes there are remnants of output left from previous expressions that have been deleted. I've also had problems with the notebook seemingly getting out of sync and text randomly appearing or disappearing occasionally. This is with up-to-date versions of Sage running on the latest Ubuntu 9.10, and recent versions of Firefox. I'm kind of losing trust in the Sage notebook and the Sage server. It seems like my notebooks are always at risk. I've dealt with buggy software before, but what's so frustrating about Sage is that there is nothing I can really do to back things up or version them. Even downloading all the notebooks as a zip file fails with some frequency and takes forever even if it works, and now I can't even upload the manual backups I created. Is there any light at the end of the tunnel? Are there any new facilities on the horizon for versioning and copying notebooks? One thing that would help a great deal is if notebooks were actually stored in a Mercurial repository and versioned using Mercurial. That way, I could pull/backup copies directly, synchronize Sage installations, and have a much more reliable record of the history of the collection of notebooks.

Is there any light at the end of the tunnel? I think so. The notebook was recently split out of the Sage library, which may have introduced new bugs, but is probably going to be worked on a lot more this next month as well. Throughout most of its history the notebook has been relatively stable (for me at least). Are there any new facilities on the horizon for versioning and copying notebooks? The notebook used to save snapshots very often, with the downside that the worksheet directories got huge. There's definitely the demand to put that in in some form or another. Other bugs may have been introduced with the switch of the notebook to a separate spkg rather than as part of the library itself.

That way, I could pull/backup copies directly, synchronize Sage installations, and have a much more reliable record of the history of the collection of notebooks.
