Cysignals not compatible with glibc >= 2.34 (fedora-35, ubuntu-impish)

[gh-kliem]

As reported on ​https://groups.google.com/g/sage-devel/c/Wz5Rhjnn4sU/m/rUd1PQbwAwAJ.

Cysignals is not compatible with glibc >= 2.34. Fedora 35 is using it and other systems will follow.

This is the cysignals issue: ​https://github.com/sagemath/cysignals/issues/150 and this is intended to solve it: ​https://github.com/sagemath/cysignals/pull/151.

I was able to build stable and develop branches with the proposed solutions. It seems to be some problems with giac, see ​https://trac.sagemath.org/ticket/32828#comment:11 for details.

I have problems with testing in develop with python3.10. Almost any test yields

in 9.4 with this packages (and also #32828 to be able to build) I get the following errors (I do not know if related with cysignals):

[gh-kliem]

Looks like a follow up on #30975 is needed.

[mkoeppe]

I would guess that this goes away with #32828.

[enriqueartal]

Replying to mkoeppe:

I would guess that this goes away with #32828.

I made the test in two situations. One was in the branch #32828, merged with develop, python3.10, and the corrected cysgnals package. The other one was 9.4 with the corrected cysignals package and also the packages pyzmq and setuptools of #32828 (if not, it is not possible to build in Fedora 35).

Summarizing, the stable build produced some failed tests (quite a number, actually) but most tests were successful. For the python3.10 build, no test passed but I could use it for my work. Actually #32828 is the branch where the tests are done, merged with develop

[gh-kliem]

I would say that cysignals is ready to be released.

I opened ​https://github.com/sagemath/cysignals/issues/157 for this. Not sure, how to proceed from here.

[mkoeppe]

@embray, @vdelecroix, please see ​https://github.com/sagemath/cysignals/issues/157#issuecomment-979756762, could you please give @kliem and perhaps other Sage developers access to the cysignals project on PyPI?

[dimpase]

I don't have access to SageMath pypi. Is it done using a token, or in some other way?

[mkoeppe]

Current "owners" of the project (embray, vdelecroix, jdemeyer) can invite other users to be maintainers or owners using the link ​https://pypi.org/manage/project/cysignals/collaboration/

[mkoeppe]

I have just sent out invitations to become owner of some of the PyPI projects that I created (​https://pypi.org/project/sage-conf/, ​https://pypi.org/project/sage-setup/, ​https://pypi.org/project/sage-docbuild/, ​https://pypi.org/project/sage-sws2rst/, ​https://pypi.org/project/sagemath-standard/) to a few people, in order to avoid similar bottlenecks in the future.

[mkoeppe]

Thanks, Vincent, I now have access.

[gh-kliem]

New commits:

​53cfadf

update cysignals to 1.11.0

[git]

Branch pushed to git repo; I updated commit sha1. New commits:

​5ed4717

update cysignals to 1.11.1

[gh-kliem]

Next time I'll hopefully remember to first try the tarball in sage.

[dimpase]

it affects sufficiently up to date Gentoo, as well.

[mkoeppe]

Fixes the build on fedora-35.

[gh-kliem]

Thank you.

[enriqueartal]

Thanks for your work!

[gh-mbombar]

Hi, I am trying to build sage on fedora-35. Cherry-picking the commits doesn't seem to be sufficient. More specifically if I cherry-pick, then while building sage, it tries to download cysignals-1.11.1 from the mirrors, but they don't have it, quite obviously.

What do I need to do to tell sage to use this fix ?

[enriqueartal]

./configure --without-system-python3 --enable-download-from-upstream-url and ./configure --enable-download-from-upstream-url worked for me on fedora-35. The git branch #30767 contains everything needed to build in fedora-35 (and some more tickets).

[gh-mbombar]

Ah yes indeed it works thanks. I didn't know about this option --enable-download-from-upstream-url.

[gh-kliem]

You can also just manually download the package by the url in checksums.ini into the folder upstream.

Thanks for verifying.

[cypari-2.1.2] Instead, the following commands setup all environment variables
[cypari-2.1.2] correctly and load a subshell for you to debug the error:
[cypari-2.1.2]   (cd '/var/lib/buildbot/slave/sage_git/build/local/var/lib/sage/venv-python3.9.7/var/tmp/sage/build/cypari-2.1.2' && '/var/lib/buildbot/slave/sage_git/build/sage' --buildsh)
[cypari-2.1.2] When you are done debugging, you can type "exit" to leave the subshell.

At the release of 10.3 they were merged into master, but not into 10.x.0. When I started with this release of cysignals, I wasn't aware of this mess.

Running tests in Fedora 35 on this branch merged with develop and #33013, most of the failures are gone. The timed out failure is also gone if applied directly.

[mkoeppe]

Tests on GH Actions look OK.
