[sage-devel] jupyterlab on sage 10.2

[Jan Groenewald]

Hi

sage 10.2 on Debian 12, and
sage -i jupyterlab

sage --notebook=jupyterlab

launches, and the logo displays and animates, and then stops. I can't get
further. Any ideas?

This was working in sage 10.1.

Regards,
Jan

Is this (repeated printing of "you need to sudo apt install") able to be
fixed? It trips up many of our students as well.

Thank you for editing that!

The wiki page is titled gitl**b but the content is about github only, not
gitlab:

* How would a gitlab workflow work better or worse than github? Especially
the CI/Actions. Even if the preferred workflow is possible to implement in
either platform, their preferred philosophy will impact future features.

 I don't know how accurate the below articles are, but found them

https://www.zdnet.com/article/github-vs-gitlab-the-key-differences/
https://www.incredibuild.com/blog/gitlab-vs-github-comparison (Flow and CI
sections)
https://radixweb.com/blog/github-vs-gitlab#difference
I can't tell which workflow is better for sagemath. Remember feature parity
betweenm them will also change every few months!

Also see what they say about themselves/each other:
https://about.gitlab.com/devops-tools/github-vs-gitlab/
https://resources.github.com/devops/tools/compare/
"""

Also the point that GL offers free private repos... if that is
necessary/useful.

Is someone able to update the wiki with equivalent guide-to-new-workflow
for gitlab so they can be compared? Is that necessary or not?

Jan

Re: [sage-devel] Re: Trac no longer seems to push to sagetrac-mirror

[Jan Groenewald]

Hi

Does someone know whether it is safe to run this manually, as the git user,
on the trac server, to test pushing?

root@trac:/srv/git/repositories/sage.git# cat
broken_hooks_02-sagetracmirror
#!/usr/bin/env bash
git push --mirror sagetracmirror

I am not comfortable with the trac/git side of things on the server (only
with the postfix/certbot/ubuntu packaging stuff).

Regards,
Jan

The current version is 1.1.6. the packaged version for the new server is
1,.2, It seems even numbers are stable but the next and latest packaged
version on debian/ubuntu is 1.5.3; 1.5+ is python3.

Trac upgrade guide is 1.0 -> 1.2 -> 1.4
https://trac.edgewall.org/wiki/TracUpgrade

Maybe the OS package upgrades support 1.2 -> 1.5.3.

I am going to look at 1.1.6 -> 1.2 packaged version on a trac-test copy of
the VM but I must say the gitolite error put me off a bit, even if it is
just disabling sshkeys.py for a bit. Then Frederic found other problems in
ticket_branch.py/pygit2.

Jan

Re: [sage-devel] Trac SSH key change

[Jan Groenewald]

For what it is worth, this seems to be when/why the host keys changed:

root@trac:~# grep -B1 \ google-compute-engine$ /var/log/apt/history.log
Start-Date: 2022-08-28  *11:13:16*
Commandline: apt install google-compute-engine
root@trac:~# journalctl |grep Instance\ ID
Aug 28 *11:13:18* trac google_guest_agent[30286]: Instance ID changed,
running first-boot actions
root@trac:~# ls -l /etc/ssh/ssh_host_ecdsa_key*
-rw--- 1 root root 227 Aug 28 *11:13* /etc/ssh/ssh_host_ecdsa_key
-rw-r--r-- 1 root root 171 Aug 28 11:13 /etc/ssh/ssh_host_ecdsa_key.pub

I installed google-compute-engine after the OS upgrade because:
root@trac:~# apt-cache show google-compute-engine|grep Replace
Replaces: gce-cloud-config, gce-compute-image-packages (<< 20191115),
gce-daemon, gce-startup-scripts

(Wasn't expecting a host key change though, my apologies)

Jan

Re: [sage-devel] Re: 32768

[Jan Groenewald]

Hi

I was interested in African universities and supporting 32 bit until about
2-3 years ago.

It is less than 1% of (science) students' laptops now, in my experience.
And all institutional machines are 64bit.

Regards,
Jan

Why did SageMath say this? Was it checking for runtime libffi or headers?

Do you perhaps need to sudo apt install libffi-dev?
It is listed as a dependency here:
https://doc.sagemath.org/html/en/installation/source.html

(also see https://bugzilla.redhat.com/show_bug.cgi?id=837102 from 2012)

Re: [sage-devel] Sage on Windows

[Jan Groenewald]

Correct output will follow when she figures out how to run coreinfo -- it
just opens a terminal and closes quickly.
That is not the right output.

Yes, though our students who start sage by clicking an icon, will never
read the warning in the terminal. Would be nice if the warning showed in
Jupyter as well.

Or maybe keep fixing the permissions unless an enviroment variable is set,
e..g SAGE_ALLOW_INSECURE_DOTSAGE.

[sage-devel] sage 8.9 crash on older CPU

[Jan Groenewald]

Hi

I have compiled sage 8.9 on a KVM used as a master image for a computer lab.
The CPU is presented as model name  : Intel Xeon E3-12xx v2 (Ivy Bridge)

Imaging is using systemimager based on rsync.

On the newer lab machines with Intel(R) Core(TM) i5-3470 CPU @ 3.20GHz
the sage copied to the lab machines works fine.

On the older lab machines with Intel(R) Core(TM)2 Duo CPU E8400  @
3.00GHz
there is a crash as attached.

Is there a flag I can set at compile time to compile for the older CPUs by
disabling use of some instruction not available on the older CPUs, which is
what I suspect is happening?

Regards,
Jan

Re: [sage-devel] Re: embedding sage in c or c++

Hi

I missed the rest of this thread, but...

Use

./sage --python

where the ./ indicates the sage command is in that folder you are located
in.

For convenience, you can make sage an alias with

echo '/home/abc/Downloads/SageMath/sage' | tee -a /home/abc/.bashrc ;
source /home/abc/.bashrc

You can then just type sage in any folder.

Regards,
Jan

Re: [sage-devel] GNU/Linux debian sid/testing: "Error building Sage" 8.3 from git

Testing is usually about 10-20 days behind unstable ("sid").

Testing will also become the new stable, so uses "buster" already.
If your sources.list has "buster", you will become stable; if it has
"testing" you will continue ahead of buster once it becomes stable.

In any case testing/sid is not something, but testing and sid are very
close.

Hi

Just a guess, but...
Try remove /Applications/sage-8.2/upstream/setuptools-38.2.4.zip and then
try build again.

Hi

This is possibly gcc 6.2 related: ​
https://mail.coreboot.org/pipermail/coreboot/2016-December/082739.html

And a possible solution is Build GMP --with-pic, (only) if GCC defaults to
-pie (preferred solution from reading the rest of above thread to the end).

Yes, must be the debian libgmp, it was not in a sage shell.

This will be configurable in future versions of jupyter (not the version on
debian stable) in ~/.jupyter via mathjax_config.

For now had to move aside the following file and instead create a symlink
/usr/share/javascript/mathjax/config/TeX-AMS_HTML-full.js to my preferred
config instead.

Jan

Yes, I completely removed ~/.mozilla, it still does not work to edit
/usr/lib/python2.7/dist-packages/notebook/templates/notebook.html.
Maybe {{mathjax_url}} is not set and so that if statement is never entered?

Anyway, this worked for now, it seems. I will deploy this:

cd /usr/share/javascript/mathjax/config
mv TeX-AMS_HTML-full.js{,.orig}
ln -s TeX-AMS_CHTML-full.js tex-AIMS_HTML-full.js

so I get a symlink to use Common HTML instead of HTML-CSS:

root@muizenberg:/usr/share/javascript/mathjax/config#ls -l
TeX-AMS_HTML-full.js
lrwxrwxrwx 1 root root 21 Sep 20 12:16 TeX-AMS_HTML-full.js ->
TeX-AMS_CHTML-full.js

Jan

Just like that previous poster (in docker), if inside my VM I do:

cd upstream; tar xf ecm*; cd ecm*; ./configure; make

then the build succeeds.

This persists with SAGE_FAT_BINARY=no and rerunning make as well.

This occurs inside a libvirt/qemu virtual machine.

When I build on the host OS, also Debian 9 it compiles OK.

[sage-devel] How to configure default mathjax rendering method in jupyter notebook

[Jan Groenewald]

Hi

I am running the debian 9 packaged sagemath-common and sagemath-jupyter.
This gives a jupyter notebook which can open sage-7.4 worksheets.

LaTeX is rendering horribly by default: short ugly integral signs shorter
than the expression that follows, and broken square root signs, amongst
other.

It can be fixed by on each formula, each time you open the notebook, right
click, math settings. Math Renderer, change HTML-CSS to Common HTML or SVG.

How can this setting be made permanent? (For oneself or many users across a
campus.)

Mathjax is loaded from libjs-mathjax, a locally installed package, not from
the internet. However editing
/usr/share/javascript/mathjax.config/default./js does not help either:

0 root@jan-desktop:/usr/share/javascript/mathjax/config#grep input/TeX
default.js
  //  input/TeX
  jax: ["input/TeX", "output/SVG"], # default was output/HTML-CSS

Any idea?

Regards,
Jan

We'd like to see sagemath in debian in backports. A PPA in Ubuntu could
serve the same purpose.

More important, no more need for a monolithic binary repackage of sagemath
for Ubuntu. That was a temporary workaround to get automatic updates via
apt.
A new PPA should inherit from backports, not just the simple binary blob of
files repackage I did of the sagemath binary tarball release.

sagemath is now properly modularised in debian, and sage8.0 is in
experimental.

Jan

[Jan Groenewald]

Hi

Since sage is now in debian, the PPA is unlikely to be updated often, if at
all.
On a new ubuntu, sage is inherited from Debian. If someone is interested in
maintaining that feel free to contact me off-list.

Jan

Better to attach a (text format) log file or cut and paste relevant lines,
so readers don't have to open images.

Your one screenshot says "Temporary failure in name resolution" which
indicates a networking error on your side.
Maybe test with ping sagepad.org

Thanks. I've just uploaded 7.5.1 to https://launchpad.net/~aims/+

Note it is the sagemath-dev repo not the sagemath repo. Would you be

I am having a closer look at the debian packaging now. To have a smaller
package, we split out the src tree and so manually list files in the
debian/install file. This breaks almost every update.

Luckily sage (7.4) is in debian testing now, which will soon be stable.

Jan

In Africa we have connectivity and power issues, which requires a local
notebook.

Would jupyter be a possible replacement for sagenb if sagenb is
discontinued from active development?  Is it already on a stand-alone
sagemath install?

[sage-devel] Cannot run sage in postinst

[Jan Groenewald]

Hi

I'm preparing the PPA for sage 7.4. In the postinst script I run sage once
as root to set hardcoded paths (which may have been replaced by
replocate-once.py??).

It fails to run under apt or dpkg --configure with

/usr/lib/sagemath/local/lib/python2.7/site-packages/prompt_toolkit/terminal/vt100_input.pyc
in __init__(self=, fileno=0)
--> 409 self.attrs_before = termios.tcgetattr(fileno)
error: (25, 'Inappropriate ioctl for device')

But I can run sage in a terminal. Is it safe to remove 'running sage once
as root to set hardcoded paths' from the postinst?

Jan

Re: [sage-devel] Re: crash after compiling sagemanifolds sage 7.3 (ppa aims)

[Jan Groenewald]

Thanks, that was the second time. Third time also failed at 10 minutes
without buildlog.
launchpad does that sometimes but ususally 1 (or 2)  retries are enough.
4th retry is now showing a buildlog, and busy building, and is at 33
minutes, give it 30 more or so.

https://launchpad.net/~aims/+archive/ubuntu/sagemath-dev/+packages
<https://launchpad.net/%7Eaims/+archive/ubuntu/sagemath-dev/+packages>

Watch the build
https://launchpad.net/~aims/+archive/ubuntu/sagemath-dev/+build/10947743
which take s about an hour. If successful, publishing that in the PPA could
take anything
from 5 minute to 5 hours, depending on how busy launchpad is.

Please send me feedback before I copy to the stable PPA. I can't test that
this even opens the notebook now.

Regards,
Jan

Re: [sage-devel] Re: crash after compiling sagemanifolds sage 7.3 (ppa aims)

[Jan Groenewald]

Hi

Thanks, Eric. The PPA for 16.04 is indeed the 14.04 binary in the PPA
copied forward. Let me look at what (time) it takes to upload the proper
16.04 binary.

In principle, I can continue to maintain and increase automation of this,
but time might become an issue. We have a customized Ubuntu called
aims-desktop that we redistribute, and first created the PPA for that. I
know it is used much more widely. For redistribution we contacted
Canonical's legal department after their IP policy was in the news, and
were told to redistribute modified copies we must 1) remove all Ubuntu
branding and rebuild *all*  So in future our incentive to spend time on
this might reduce.

Of course it is still not recommended to run sage -b as root and even less
so in the PPA. The PPA was always viewed as a temporary solution while
people are working on properly debianizing sage, a hard and multi-year
project, which will no doubt leave Debian/Ubuntu with a outdated sage.

Still we want to support knowledgable people doing this out of necessity
while sage-in-debian is not ready.

Regards,
Jan

[sage-devel] Fwd: SageMath packaging status update

[Jan Groenewald]

Might of interest to some here.  Please join the mailing list if you can
help.

-- Forwarded message --
From: Tobias Hansen <than...@debian.org>
Date: 10 August 2016 at 01:17
Subject: SageMath packaging status update
To: "debian-scie...@lists.debian.org" <debian-scie...@lists.debian.org>


Hi Debian Science,

I thought I'd give you an update about the packaging of SageMath in Debian.

Since the last update we have improved our methods quite a bit. We now
have a mini-dinstall (our own little APT repository) which allows us to
always have a set of packages available that makes it possible to build
SageMath. We have an up-to-date SageMath (7.3) that can be built using
Debian packages to fulfill most dependencies. One can run the test
suite, but we didn't create an installable package yet.

We are currently working on packaging the last small dependencies and
making the tests pass. Help is always welcome, it would be awesome if we
could manage to ship SageMath in Stretch. More details can be found on
the Wiki page [1].

Since today we also have our own mailing list to discuss issues
regarding SageMath packaging. [2]

Best,
Tobias

Yes, changes to sage's patching of files broke the part of the PPA.

Yes, we now plan to run relocation before rather than after creating
uploading to the PPA since I yesterday submitted a patch to give it a
destination folder as a command line argument. It was not possible before.
We will not need to move it again after that.

If you run sagemath-upstream-binary-full it is technically possible to run
sage manifolds. We had this deployed on campus last week. But you have to
reinstall it after every upgrade. It is bad because:

1) you should not compile as root. There is a past bug where compiling some
package would delete a system file [1]
<http://trac.sagemath.org/ticket/9551>. Malicious code could hose or
rootkit your system. We plan in future to have the sage tree owned by a
sagemath user, which will alleviate that (only) if people remember to
change to that user before customizing / adding optional packages and
rebuilding.

2) bad practice since dpkg (or your distro package manager) is supposed to
manage the system files, but it is technically possible.

It will not work with sagemath-upstream-binary (without -full) since the
SAGE_ROOT/src folder is missing and many files you need for rebuilding sage.

I will try to release a 7.0.1 (rather than waiting for 7.1) which also
fixes the smaller sagemath-upstream-binary in the PPAs. Note 7.0 is now in
the stable PPA for 14.04.

Jan

I'm under the impression almost all software works relocatable, and only
start off hardcoded due to time pressure, but then get fixed.
Is it difficult because of legacy code?

Does it matter for the PPA? Isn't that installed in a fixed location anyway?


Yes, changes to this it is what broke the PPA since 6.9. I didn't catch it
between dev and stable because I run the -full version.

My head explodes that sage patches binaries after compilation to fix
hardcoded paths.

If I google "hardcoded paths" then there are mainly results about how to
fix having hardcoded paths.
I don't know which parts of Sage or packages in Sage do not support
prefixes. It seems bizarre.
Are there just not enough people working on the build side of Sage? Does
most of the sub-packages not support
prefixes?

Jan

So it seems (with difficulty) Conda patches binaries as well:

http://conda.pydata.org/docs/building/meta-yaml.html#relocatable

To make them use relative paths...?

OK, so Sage is trying to make something you can install anywhere in the
homedir (like on a laptop for a single user) not a system-wide install via
a package manager (like in a computer lab with low personal disk space
quotas; or laptop users with inexperience with self-compile skills)? And
places like sagemathcloud or sage servers for multiple users all compile in
place?

Jan

OK, I'll retract that, perhaps I was thinking of software "trees",
including all shared libs and so on.

But can I say most binaries should not have hard-coded paths patched just
after compilation?

Most developer and science software are compiled in place.

Nothing on my Debian, Ubuntu, Fedora, Redhat, etc. systems are compiled in
place.  The files are put there by a package manager.

I can't move a binary but I can move a package.

0 jan@kontiki:~$cp /usr/lib/firefox/firefox .; ./firefox # <-- one binary
without libs
Could not find the Mozilla runtime.
255 jan@kontiki:~$rm firefox
0 jan@kontiki:~$cp -R /usr/lib/firefox .; ./firefox/firefox # folder with
interdependent libraries and relative paths
0 jan@kontiki:~$# worked!
0 jan@kontiki:~$

Most software go ./configure --prefix=path; make; make install

and installs to elsewhere with known paths for shared libraries, or
relative paths for in-package libraries and you can move the tree.

Does sage not ever hope to get to that (despite me not knowing the build
process and non-trivial work involved in this?

The binary patching is a second option if you don't want hardcoded paths in
> the binary you download.


hardcoded absolutenot relative (to SAGE_ROOT) paths??

[sage-devel] Re: recent woes with relocation of SageMath installation directory

[Jan Groenewald]

full
sudo mv /etc/apt/sources.list.d/aims-sagemath-dev-trusty.list{,.disabled}

Notes:

The plan is (probably) for 7.1 is to move the relocate-once.py out of the
first run of sage during debian/postinst, and to do it in our autobuild.sh
before it runs dpkg-buildpackage to prepare the source package for upload
to the PPA. This way we can keep both the larger and smaller versions.

If you are going to do the unwise and unsupported thing of compiling
optional packages as root on dpkg-owned directory, you will need the -full
package. We plan to change the user owning the files so that even if we
break debsums we don't have to compile as root to customize a PPA install.

I have no idea where to start, but perhaps there should be a ticket to make
sage relocatable? Patching paths in binaries after compilation blows my
mind.

Jan

[sage-devel] Re: [sage-release] Re: recent woes with relocation of SageMath installation directory

Hi

Yes, that is the Ubuntu PPA. The installation is mostly working despite
that error message.
(We have it running on campus while courses are using sage for the last 3
weeks.)

I'm waiting to see a use case that warrants reverting, despite the lack of
confidence that this message inspires.

Re: [sage-devel] Re: Missing file in src/build/cythonized/sage/structure/list_clone.c

[Jan Groenewald]

Hi

Yes, I am getting some queries directly to me as well (as PPA maintainer).
The SAGE_ROOT/relocate-once.py is becoming less compatible with
dpkg-buildpackage, which wants to manage the files, and not have them
changed after installation.

We're thinking of a new simpler package, which contains the tarball, and
has a script to untar it.

We're still discussing the various options around this. Our criteria are:

1) prompts for updates in the distro package management system (gets our
alumni body to actually update)
2) ease of install. In fact we pre-install it for most of our users via a
Ubuntu derivative
3) save bandwidth and disk space (we'll have to drop the smaller version
now and include the  whole tarball with the SAGE_ROOT/src folder)
4) have a local to each laptop version (not a cloud server or campus
server) for situations with both bandwidth and electricity interruptions

So far this error does not inspire confidence, but this PPA 6.10 is
deployed on our campus where people are using sage in teaching and I have
not had to revert to 6.9.

Regards,
Jan

[sage-devel] Missing file in src/build/cythonized/sage/structure/list_clone.c

Hi

The sagemath-upstream-binary in the PPA which excludes most of the src
folder, gives this error on startup:


Rewriting paths for your new installation directory

This might take a few minutes but only has to be done once.

(I get this from sagemath-upstream-binary-full which includes the src
folder)

Funny thing is, basic operations ad plotting work fine, whereas I thought
if relocate-once.py failed sage would not be able to find any of it's
libraries and just crash.

Yes, I'm sure, we get that traceback during running sage once as root in
the postinst script.
Then agani whenever starting sage.

I do NOT get that when I have sagemath-upstream-binary-full installed
(which includes the src folder).

[sage-devel] Re: update of sagemath ppa

[Jan Groenewald]

Hi Wilfried

We are busy working on it; due to some filename and layout changes in sage
this has been delayed a bit.

We have a dev PPA where we test sage (and it currently contains a broken
sage!).
https://launchpad.net/~aims/+archive/ubuntu/sagemath-dev/+packages

I expect to have a working sage in the dev PPA by the end of the week, and
to deploy it in our computer labs for 2-3 days before copying to the stable
PPA.
I might let you know when I have a working sage in the dev PPA. If you
enable both the stable and unstable PPA, you can get updates, and revert to
a working version with, for example

sudo apt-get install sagemath-upstream-binary=6.9 # will of course use some
bandwidth.

(or if you run sagemath-upstream-binary-full then add the -full; the -full
has the German documentation; the smaller package is missing most of the
src folder except the en and fr documentation; the -full adds all other
files back).

Hmm, I seem to have uploaded a version that works, (to dev PPA) though if
you have minimal and full installed you have to install full first. So I
will try a bit more to fix that.

Regards,
Jan

Re: [sage-devel] Re: sagemath 6.9 Ubuntu PPA: Error typesetting mathematics

[Jan Groenewald]

A new install from the PPA will work. It is unfortunately some upgrades
since 6.6 that don't. Maybe we can add a sage-fix-mathjax.sh script. Or do
it in postinst. I think we did for a while.

[sage-devel] Re: sagemath 6.9 Ubuntu PPA: Error typesetting mathematics

[Jan Groenewald]

Hi

This might be a leftover error from a previous versio nwhen mathjax moved.
Please try

sudo -i
cd
/usr/lib/sagemath/local/lib/python2.7/site-packages/sagenb-0.11.4-py2.7.egg/sagenb/data/
rm -rf mathjax
ln -s ../../../../../../share/mathjax/

Or inspect first whether that symlink is there already?

If it is actually a PPA error (I doubt it, I think we fixed in 6.6) we will
look at uploading a fix.

Regards,
Jan

Re: [sage-devel] SSL

[Jan Groenewald]

Hi

I cannot figure out why the buildslave binary cannot import ssl when
Thierry's binary and from-source-build can import ssl:

1 jan@muizenberg:/srv/sysadm/t$echo import ssl | ./sage-6.8/sage -q
#from-source
sage: sage:

sage:

0 jan@muizenberg:/srv/sysadm/t$

This is why the PPA package cannot import ssl, it is based on the
buildslave binary.

Any ideas?

From-Source is worst, same as the binaries: needs sage -pip install
pyopenssl, but even that look ssuccessful and then the notebook still does
not see it!

Not out of the box. But with pyopenssl. This is from your binary:

[sage-devel] SSL

[Jan Groenewald]

Hi

I'm not sure. Can we move this thread to sage-devel and ask there?

This was more about getting at least a working PPA out. I will follow on
sage-devel though.

Basic question: What does it take to enable SSL? Do those commands work on
1) source build
2) binary (LTS)
3) PPA

Regards,
Jan

Hi William,

Please add me too.

We'd be happy to help with what we already do: buildslaves for
Debian/Ubuntu, PPA autobuild, perhaps some of this can be migrated onto
those servers. We're most comfortable working on Debian/Ubuntu with LXC.

We're getting quite comfortable on Ubuntu or Debian running LXC containers.
We're in progress of replacing backup scripts with backuppc, and we're
interested
to move to ansible (or another) as soon as we have time. If everyone else
here is more of a
mathematician / programmer than sysadm, then yes, 13 years ago I moved from
math
to sysadm, and that is our focus.

I must confess our availability is not good at all, and a main goal for us
would be to move
buildslaves and PPA autobuild LXC containers (and their backups) from our
Hetzner.de
to some of these machines, to free up CPU for our institution. Our total
hardware is less
than you are talking about here. We'd be more than happy to continue to
maintain and to
document those, and over time might become more available for other tasks,
and we're
certainly interested in following. It would be a doable task to make
available containers
for anyone who wanted to maintain a container buildslave for any other
Linux distro.
Perhaps one host could be dedicated for that?

We'd also be very interested in learning from any implemented cluster
architecture, configuration
management, and have some very minimal use of ansible.

Regards,
Jan
