%global _description %{expand:
trame-rca (Remote Controlled Area) streams rendered images and frames
from a Python server to a browser-side viewport over WebSocket.
trame-slicer uses it to push 2D/3D slice views and DICOM renderings
to the web client without copying full meshes over the wire.}

# The trame namespace dirs (trame/, trame/ui/, trame/modules/, trame/widgets/) are
# shared by several trame distributions, and every wheel ships its own copy of the
# pkgutil marker __init__.py. The .py files are byte-identical so rpm tolerates the
# duplicates -- but their .pyc embeds the SOURCE MTIME, which differs per build, so
# the bytecode collides at install time:
#   file .../trame/ui/__pycache__/__init__.cpython-314.pyc conflicts between
#   attempted installs of python3-trame-... and python3-trame-client-...
# Since Python 3.3 these work as PEP 420 implicit namespace packages with no marker
# at all, so drop it everywhere. Verified: with all four removed, trame.ui becomes a
# _NamespacePath and trame.ui.vuetify3 / trame.widgets.vuetify3 / trame.modules.www
# still resolve across packages. The grep guard makes sure a real __init__.py with
# actual code is never deleted.

%changelog
* Fri Aug 22 2026 Morgan Hough <morgan.hough@gmail.com> - 2.7.0-2
- Drop the pkgutil namespace markers for trame/{,ui,modules,widgets} and rely on
  PEP 420 implicit namespace packages. Every trame wheel ships its own identical
  copy; rpm tolerates the duplicate .py (byte-identical) but the .pyc embeds the
  source mtime, which differs per build, so installing two trame packages together
  failed with __pycache__/__init__.cpython-314.pyc file conflicts.

* Sat Jul 18 2026 Morgan Hough <morgan.hough@gmail.com> - 2.7.0-1
- Update to 2.7.0

* Sat Jun 27 2026 Morgan Hough <morgan.hough@gmail.com> - 2.4.3-2
- Rebuild against Python 3.15 (rawhide). Release bump so the py3.15 build
  supersedes the lingering same-NVR py3.14 RPM in the COPR repo.

* Thu May 28 2026 Morgan Hough <morgan.hough@gmail.com> - 2.4.3-1
- Initial package for the trame-slicer dependency chain.
