[Bug 2095581] Re: [MIR] libsass-python

[James Page]

This feels like it was a lesser of two evils type decision - pyscss was
the previous Sass compiler which has not had any updates since 2022:

  https://github.com/Kronuz/pyScss/commits/master/

libsass and libsass-python have more recent commits (mainly maintenance
stuff):

  https://github.com/sass/libsass/commits/master/
  https://github.com/sass/libsass-python/commits/main/

Given alternatives are not in archive and potential have much different
security postures this feels like a modest improvement in terms of
security risk exposure from the current status quo of pyscss.

Title:
  [MIR] libsass-python

Status in libsass-python package in Ubuntu:
  New

Bug description:
  Switch in horizon from pyscss and associate django plugin to libsass-
  python and the native library it wraps.

  https://review.opendev.org/c/openstack/requirements/+/934220

  https://opendev.org/openstack/horizon/commit/283219ab5ef4344e3808cd61b4cc0821886acffb
  https://opendev.org/openstack/horizon/commit/283219ab5ef4344e3808cd61b4cc0821886acffb

  
  libsass-python MIR

  [Availability]
  The package libsaas-python is already in Ubuntu universe.
  The package libsaas-python builds for the architectures it is designed to work on.
  It currently builds and works for architectures: amd64, arm64, armhf, ppc64el, riscv64, s390x
  Link to package https://launchpad.net/ubuntu/+source/libsass-python

  [Rationale]
  The package libsass-python is required in Ubuntu main because Horizon has switched from pyscss to libsass-python and the native library it wraps.
  The package libsass-python will generally be useful for a large part of our user base.
  The package libsass-python is a new runtime dependency of package OpenStack Horizon that we already support.

  There is no other/better way to solve this that is already in main or
  should go universe->main instead of this.

  The binary package libsass-python needs to be in main as it is a new
  dependency for OpenStack Horizon which is switching away from the
  previously used django_pyscss.

  The package libsass-python is required in Ubuntu main no later than
  February 20, 2025 due to feature freeze.

  [Security]
  No CVEs/security issues in this software in the past

  no executables in `/sbin` and `/usr/sbin`
  Package does not install services, timers or recurring jobs
  Packages does not open privileged ports (ports < 1024).

  [Quality assurance - maintenance]
  TODO: - The package is maintained well in Debian/Ubuntu/Upstream and does not have too many, long-term & critical, open bugs.
  The package does not deal with exotic hardware we cannot support.

  [Quality assurance - testing]
  The package runs a test suite on build time, if it fails it makes the build fail, link to build log (https://launchpadlibrarian.net/758454081/buildlog_ubuntu-plucky-amd64.libsass-python_0.23.0-0.1build1_BUILDING.txt.gz)

  build time.
