The #1124 fix (824c1fc280) named its pythoncode backref helper `_geometry_with_backref` with a leading underscore. validate_stub.py's get_function_node_name() skips any leading-underscore name (its only exception is `_is`), so the helper never gets added to the parsed `subnames` set. When get_names_tree_lines() later processes `geometry = property(_geometry_with_backref)`, find_method_by_name() can't find the backing function and the `assert (wrapped_function := find_method_by_name(arg))` at validate_stub.py:154 raises AssertionError instead of the expected clean stub/wrapper diff, crashing the CI `ci.yml` -> compile-and-test -> "Test ifcopenshell-python" step (`make test-parallel`) on every push since824c1fc280. Renaming to `geometry_with_backref_` (trailing underscore) matches the existing local convention in the same class bodies for backing- implementation helpers (calc_volume_, calc_surface_area_), which validate_stub.py's heuristic already handles correctly. Also add the six new SVG edge-classification settings-flag classes (SvgEmitFlushEdges, SvgRenderCreaseEdges, SvgRenderSharpEdges, SvgRidgeAngleMinDegrees, SvgUseEdgeClassification, SvgValleyAngleMinDegrees) to ifcopenshell_wrapper.pyi. These were added to the C++/SWIG side by the SVG edge classification commits but never synced to the stub, and validate_stub would report them as a stub/wrapper discrepancy once the crash above is fixed. Reproduced by building ifcopenshell against the exact CI-tested commit (c68e4a0eee) with SWIG 4.1.0 (matching ci.yml's pinned build-from-source version) and running validate_stub.py's actual logic against the generated ifcopenshell_wrapper.py: crashed identically to the CI log before this change, passed cleanly after. test/util/scripts/test_validate_stub.py::TestValidateStub::test_run passes against the rebuilt wrapper. Generated with the assistance of an AI coding tool.
IfcOpenShell
IfcOpenShell is an open source (LGPL) software library for working with Industry Foundation Classes (IFC). Complete parsing support is provided for IFC2x3 TC1, IFC4 Add2 TC1, IFC4x1, IFC4x2, and IFC4x3 Add2. Extensive geometric support is implemented for the IFC releases IFC2x3 TC1 and IFC4 Add2 TC1. Extending with support for arbitrary IFC schemas is possible at compile-time when using C++ and at run-time when using Python.
In addition to a C++ and Python API, IfcOpenShell comes with an ecosystem of tools, notably including IfcConvert (an application to convert IFC models to other formats), Bonsai (an add-on to Blender providing a graphical IFC authoring platform), and many other libraries, CLI apps, and more. Support is also provided for auxiliary standards such as BCF and IDS.
