%description
spectrum is a Python library providing tools to estimate power spectral
densities (periodogram, multitapers/DPSS, parametric AR/ARMA methods,
correlograms, windowing functions and more).

# spectrum's setup.py wrongly installs an empty top-level "cpp" package
# (the C-extension source dir). Drop it — it pollutes site-packages and is
# not used at runtime (the extension is spectrum.mydpss).

%changelog
* Mon Sep 28 2026 Morgan Hough <morgan.hough@gmail.com> - 0.10.0-2
- Rebuild for f45's current numpy/Python 3.15. The previous build's compiled
  extensions SIGSEGV on f45 inside their own module init, found by importing
  every compiled module one subprocess each (spectrum.mydpss). Same class as
  python-surfa 0.6.3-3 and python-vispy 0.16.2-2 today: a numpy/Cython ABI
  change moves no soname, so rpm dependencies are satisfied and the package
  fails only at load. Nothing we gate on can see it -- %check ran at BUILD time
  and passed, and the environment moved afterwards.
- Note the top-level import is NOT enough to detect this: `import spectrum` returns 0
  because the package __init__ never loads the extension. Only importing the
  submodule that owns the .so trips it, which is why an earlier top-level-only
  sweep of mine missed this package entirely.
* Mon Jun 15 2026 Morgan Hough <morgan.hough@gmail.com> - 0.10.0-1
- Initial package (pyfix dependency chain, via easydev).
