# siphash24 -- SipHash-1-3 and SipHash-2-4 for Python, a C extension over the
# c-util c-siphash library. New to Fedora. Packaged because python-pytools
# >= 2025.1.6 requires it, and pyopencl 2025.2.6 (stock Fedora) cannot import
# without that pytools (Bugzilla 2432626), which leaves babelbrain with no
# OpenCL compute device.
#
# Upstream's meson build takes the two c-util libraries as wrap-git
# subprojects, i.e. it clones them at build time. Copr builds have no network,
# and Fedora wants sources in the SRPM anyway, so the pinned revisions are
# Source1/Source2 and are unpacked into subprojects/ under the directory names
# the .wrap files declare; meson then uses the directories and never fetches.
# Both libraries are static-linked into the extension, hence bundled().

* Sun Oct 11 2026 Morgan Hough <morgan.hough@gmail.com> - 1.9-1
- Initial package. Needed by python-pytools >= 2025.1.6, which pyopencl
  2025.2.6 needs to import at all (Bugzilla 2432626); babelbrain's OpenCL
  backend is behind that. The c-siphash and c-stdaux meson subprojects are
  shipped as pinned sources instead of being cloned at build time.
