Meta-ticket: Remove support for outdated distros #32074

dimpase · 2021-06-28T12:34:04Z

In particular, CI is running tests on post-EOL distros.

Here we collect tickets in roughly chronological order that required special care for old platforms, as well as tickets that drop support for old platforms.

Sage 9.4:

Drop support for optional packages with system gcc 4.x on ubuntu-trusty, debian-jessie, linuxmint-17, centos-7 #31526 (Drop support for optional packages with system gcc 4.x on ubuntu-trusty, debian-jessie, linuxmint-17, centos-7)

Sage 9.5:

{ubuntu-trusty,linuxmint-17}-gcc_spkg: numpy, ntl, nauty, ... fail to build #32281: {ubuntu-trusty,linuxmint-17}-gcc_spkg: numpy, ntl, nauty, ... fail to build
sage-bootstrap-python: Prefer pythons that support ssl with SNI #32405 sage-bootstrap-python: Reject ancient pythons that do not support SNI

update and promote spkg primecount #25009 primecount required patching for ubuntu-trusty etc. and would require patching for debian-jessie
tox.ini, GH Actions: Update Linux platforms #32947 Drop support for debian-jessie - gcc 4.9; past EOL LTS, extended LTS (commercial, separate from Debian, till June 2022), see https://wiki.debian.org/DebianReleases).
GH Actions: Remove ubuntu-groovy #33068 GH Actions: Remove ubuntu-groovy

Sage 9.6:

no changes to supported platforms
tox / GH Actions: Add centos-7-devtoolset-gcc_{9,10,11} #32965: tox / GH Actions: Add fedora/centos variants using devtoolset
tox / GH Actions: Add ubuntu variants using ppa:ubuntu-toolchain-r #32966: tox / GH Actions: Add ubuntu variants using ppa:ubuntu-toolchain-r

Sage 9.7:

Drop support for GCC < 6.3 in Sage 9.7 #33316 Drop support for GCC < 6.3, motivated by stricter compiler requirements in numpy 1.22.x, scipy 1.8.x (Update numpy to 1.22.x, scipy 1.8.x, networkx 2.8.x #32423), linbox (Upgrade to givaro-4.2.0 fflas-ffpack-2.5.0 linbox-1.7.0 #32959), e-antic/Normaliz (Update Normaliz to 3.9.x, pynormaliz to 2.17, e-antic to 1.x, add optional package antic #31588):
- ubuntu-trusty 14.04 is long past "standard support", but EOL has been extended to Apr 2024. Replace by ubuntu-trusty-toolchain-gcc_9
- Likewise for ubuntu-xenial: replace by ubuntu-xenial-toolchain-gcc_9
- centos-7 has EOL June 2024, gcc 4.x. Replace by centos-7-devtoolset-gcc_11

Soft drop of support for Cygwin

Sage 9.8:

Reduce R to a dummy package, upgrade rpy2 to 3.4.5 #34268 Reduce R to a dummy package, upgrade rpy2 to 3.4.5 -- this drops support for R on ubuntu-trusty, ubuntu-xenial, ubuntu-bionic, debian-stretch, fedora-26.
Drop support for GCC < 8 in Sage 9.8 #34266 Drop support for GCC < 8, motivated by stricter compiler requirements in scipy 1.10.x, which needs C++ 17 language support and specifically GCC >= 8 - http://scipy.github.io/devdocs/dev/toolchain.html#compilers
- debian-stretch (EOL, GCC 6.3), fedora-{26,27,28} (GCC < 8): Drop
- ubuntu-bionic and linuxmint-19.x: Default gcc is gcc-7, but a gcc-8 package is available, providing /usr/bin/gcc-8 but not /usr/bin/gcc. Replace platform by ubuntu-bionic-gcc_8 (to be defined)
- opensuse-15.0: Default gcc is gcc7, but a package gcc8 is available, which provides /usr/bin/gcc-8 but not /usr/bin/gcc. Replace with opensuse-15.0-gcc_8
- opensuse-15.3, -15.4: Default gcc is gcc7, but packages gcc8, gcc9, gcc10, gcc11 are available. Replace platforms by opensuse-15.{3,4}-gcc_11

Sage 10.0:

No platforms dropped.
New platforms: Support GCC 13 (fedora-38) #35092

Sage 10.1:

Sage 10.2:

Drop support for GCC < 8.4, drop testing of debian-buster and fedora-29 #35810: NumPy 1.25.x needs GCC >= 8.4; this refers to but is stricter than the published SciPy toolchain roadmap (as of 2023-05-06).
- debian-buster (LTS until 2024-06) only has GCC 8.3: Drop. Replace tested platform debian-buster-i386 by debian-bullseye-i386.
- ubutu-bionic-gcc_8-python3.8 has GCC 8.4, so ok.
- opensuse-15.0-gcc_8 only has GCC 8.2.1: Drop.
- opensuse-15.1 and newer have gcc9, gcc10 packages or newer; check if we need to replace currently tested opensuse-15.3 by opensuse-15.3-gcc_10.
- linuxmint-19.1-gcc_8 has GCC 8.4, so OK.
- fedora-29 (long past EOL) only has GCC 8.3.1: Drop.
- centos-stream-8 has GCC 8.5, ok.

Sage 10.5

CI: Remove centos-7 #38380 (EOL 2024-06)

Sage 10.x:

Drop support for system Python on debian-bullseye (end of standard support 2024-08), ubuntu-focal (end of standard support 2025-04) - build/pkgs/python3 3.13.0rc1, require Python >= 3.10, numpy 2.1.1, scipy 1.14.1, pillow 10.4.0, cffi 1.17.0, networkx 3.3, sphinx 8, ipython 8.26 #37006
Use and require C++17 instead of C++11 (in distro + sagelib) #37906
sage-bootstrap: Drop support for Python 2, < 3.5; port sagemath-environment to Python >= 3.5 #35858

gentoo-python3.7 is outdated too since Michał Górny disabled python3.7 in Gentoo several weeks ago :(

comment:6

I don't know anything about the build system, so maybe this is noise, but regarding the problem with __builtin_smull_overflow at #31694 and #31585 ...

I think __builtin_smull_overflow was introduced in gcc 5 and clang 3.4, so I thought it was safe to use. (I think avoiding it would make the code both more complicated and less efficient.)

In the link to the debian jessie run, I see "Unpacking gcc-4.9 (4.9.2-10+deb8u2)" and "Unpacking g++-4.9 (4.9.2-10+deb8u2)". If this means it is using gcc 4.9, then that would explain the problem. I thought support for gcc 4.9 was dropped in #31526, which means we should not be worrying about this, but I guess I hadn't read it carefully, because it seems to only allow optional packages to drop support for 4.x. Is the problem with ubuntu trusty also from using gcc 4.x?

I don't think I should have much of a say, but I am certainly +1 on dropping support for gcc 4.x entirely. That is a really old compiler.

comment:7

What about Mac OS? I've seen a claim that Apple officially supports the three most recent versions of the OS — currently 10.14, 10.15, and 11 — and (for example) Mac OS 10.11 became unsupported in August 2018, 10.12 in November 2019, 10.13 in November 2020. I don't know what impact dropping support for 10.11 would have on Sage, but I think I saw a recent post in sage-devel or sage-support from someone struggling to install Sage on this OS.

https://docs.github.com/en/actions/using-github-hosted-runners/about-github-hosted-runners only has Catalina and Big Sur. So these systems are the only ones that are systematically tested.

These are also the only versions that we claim to support (for building Sage from source) in https://wiki.sagemath.org/ReleaseTours/sage-9.3#Availability_of_Sage_9.3_and_installation_help

Without infrastructure for testing, I would be reluctant to make any claims regarding support for older OS releases.

Travis CI does support a wider range of macOS releases, keyed to XCode versions - https://docs.travis-ci.com/user/reference/osx/#macos-version, going back to OS X 10.11. I used to have a workflow on Travis CI to run some superficial tests on a built binary distribution on older macOS versions (see #31133). But there seemed to be little interest in this at the time, and I have not updated these scripts.

Marc Culler appears to be testing his new binary distribution on some older macOS versions.

comment:9

I think Apple is supporting 3 macOS releases, including the current, 11. This makes everything older than macOS 10.14 obsolete.

Reorganized the ticket description.

### 📚 Description In preparation for important package upgrades, we remove support for Python v3.8. (Almost) all occurrences of "Python 3.8" are removed from the codebase. There are still some comments left that essentially say that in newer versions things can be simplified, but I didn't touch those and leave them for follow-up PRs. This will help with: - PRs that require Python 3.9 or above, such as sagemath#34973 and sagemath#35188. - Upgrades of Python packages that have dropped support for Python 3.8 because they follow NEP 29 and have already released a new major version that drops support according to the NEP 29 schedule. - NetworkX 3.2 (expected 2023-??; version 3.1 was released 2023-04, see sagemath#35671) - sagemath#34816 - sagemath#35703 - See also sagemath#32074.

We also remove `linuxmint-19.3-gcc_8-python3.8` and change `fedora-30-python3.8` to `fedora-30` (which builds python from spkg), to prevent a merge conflict with sagemath#35404 We also add `debian-trixie` (= current testing).   ### 📝 Checklist  - [x] The title is concise, informative, and self-explanatory. - [ ] The description explains in detail what this PR is about. - [x] I have linked a relevant issue or discussion. - [ ] I have created tests covering the changes. - [ ] I have updated the documentation accordingly. ### ⌛ Dependencies   URL: sagemath#35810 Reported by: Matthias Köppe Reviewer(s): Dima Pasechnik

…tu-xenial`    On `centos-7`, still supported until June 2024, we have to use sage- bootstrap-python = python2. Support for Python 2 was broken accidentally in sagemath#36393, see https://gith ub.com/sagemath/sage/actions/runs/6520548150/job/17767608828#step:10:192 7 Fixed here, as tested with `tox -e docker-centos-7-devtoolset- gcc_11-standard -- config.status`.

Update (Apr 2024): - ubuntu-trusty reaches EOL, we drop it. Also remove some past-EOL OpenSUSE Leap; see sagemath#32074 - also reducing the list of systems tested with `--enable-system-site- packages` because there is no interest in doing the porting work - updating the default platform (used by the incremental build workflows) from `ubuntu-focal` to `ubuntu-jammy`.  ### 📝 Checklist     - [x] The title is concise, informative, and self-explanatory. - [x] The description explains in detail what this PR is about. - [x] I have linked a relevant issue or discussion. - [ ] I have created tests covering the changes. - [ ] I have updated the documentation accordingly. ### ⌛ Dependencies   URL: sagemath#37351 Reported by: Matthias Köppe Reviewer(s): Julian Rüth, Kwankyu Lee, Matthias Köppe, Michael Orlitzky, Tobias Diez
