test_file's parametrize list was filtered with `sys.argv[1] in
os.path.basename(fn)`, reading the raw process argv instead of a
pytest-native option. Under a bare `pytest` invocation sys.argv[1] is
pytest's own first CLI token, never a match, so the 138-fixture EXPRESS
rule corpus in test/fixtures/rules collapses to an empty parametrize and
pytest reports it as a single skipped test rather than an error. Under
CI's actual invocation (pytest -p no:pytest-blender -n $NPROCS test ...)
sys.argv[1] is "-p", which happens to substring-match 47 of the 138
fixtures, so CI has been silently running a coincidental 34% slice of
the corpus with no signal anything was wrong.
Replaced the module-level list comprehension with a pytest_generate_tests
hook plus a --rule CLI option (added via a new test/conftest.py). This
runs the full corpus by default under any pytest invocation, still
allows filtering to one rule for local debugging via --rule, and no
longer collides with pytest's own argv.
Verified all 138 fixtures collect and pass under the fixed harness
(63 fail- fixtures each raise a violation, 75 pass- fixtures raise none).

create(timestamp=0) computed the FILE_NAME timestring with
`d.get("timestamp") or time.time()`, which treats 0 (a legitimate
epoch timestamp) as unset because 0 is falsy. The header ended up
with the current wall-clock time in FILE_NAME while IFCOWNERHISTORY
correctly stored CreationDate=0, an inconsistent pair of dates in
the same file. Switched to an explicit None check so an explicit
timestamp of 0 is honoured the same way any other explicit
timestamp is.

get_element_value could not reach the members of an IfcPhysicalComplexQuantity
(or IfcComplexProperty) by their natural path. util.element expands a complex
quantity into a dict whose nested members live under a "properties" sub-dict,
but the selector's dict navigation only looked at the top level, so
"Qto_Custom.Layer1.Width" returned None and IfcCsv exported nothing for it.
Only the internal "Qto_Custom.Layer1.properties.Width" path worked.
When a key is not a direct member of the value dict, descend into its
"properties" sub-dict so nested quantities/properties resolve with the
natural "Set.Complex.Nested" path. Direct keys still take priority, so the
explicit ".properties." path stays backward compatible and the regex branch
is untouched.
Verified: Qto_Custom.Layer1.Width -> 0.1 and Layer1.Height -> 2.5 (were
None), the sibling simple NetArea still resolves, the legacy .properties.
path still works, and IfcCsv now exports the nested value. test_selector.py:
38 passed (adds test_selecting_a_nested_complex_quantity).

When replacing a style on an item whose previous IfcStyledItem wraps its styles
in the deprecated IfcPresentationStyleAssignment, and the assignment is not
being reused (use_style_assignment is False, e.g. an IFC4 file authored by
AVEVA E3D), the else branch called remove_same_type_styles(style_assignment)
with style_assignment still None, raising
AttributeError: 'NoneType' object has no attribute 'Styles'. Operate on style_,
the assignment found in the current iteration, instead of the accumulator.
Verified red-green with a minimal IFC4 file using IfcPresentationStyleAssignment.

compare() recursed into list values passing the negated comparison through,
so != meant "at least one item differs" and both = and != matched the same
elements on any multi-valued property (e.g. an enumerated property with two
values selected). Strip the negation for the per-item comparison and negate
the aggregate instead, so != means "no item equals" and stays the complement
of =. The same applies to !*=.

Per aothms's review comment: this file's schema was already changed
independently on v0.8.0 since this branch was created, so this PR's own
edit conflicts with it. Reverting to the current upstream version of the
fixture; the bsdd.py rate-limiting fix is untouched.
replace_attribute() rewrites references inside aggregate attributes via
element.walk(), but never checked whether the replacement value was
already present elsewhere in the same aggregate. For an EXPRESS SET
(e.g. IfcProject.RepresentationContexts, IfcRelAggregates.RelatedObjects)
this can leave the same reference listed twice, which is invalid IFC.
LIST and BAG aggregates legitimately allow duplicates, so a blanket dedup
would be wrong; only SET-typed attributes are deduplicated, determined at
runtime from the schema declaration (IfcOpenShell#8706 review comment).
The SET/LIST/BAG check is cached per (schema, class, attribute index), and
the dedup pass itself only runs when a cheap linear pre-check finds the
replacement value already present in the aggregate, so the common case
(no duplicate produced) pays only that pre-check, not a hash-set rebuild.
Benchmarked against a 23MB (431k entities) and a 104MB (2.4M entities) IFC
model against a large SET attribute: worst case adds well under 1ms per
call; the realistic case (merging duplicate contexts, matching the PR
#8706 scenario) shows no measurable regression.
Fixes the root cause flagged in IfcOpenShell#8706 (Moult), obviating the
need for MergeDuplicateContexts' own manual aggregate-dedup pass for that
scenario.

Fixes issue #3910's documentation gap. IsDefinedBy() returns
IfcRelDefinesByProperties relationship objects, not the property set
itself, and RelatingPropertyDefinition() must be used to reach the
IfcPropertySet or IfcElementQuantity. Properties can also come from an
element's type via IsTypedBy() -> RelatingType() -> HasPropertySets(),
a path that is easy to miss because it works differently. Adds a
worked, beginner-commented, compilable example covering both paths.

assign_cost_item_quantity skipped every IfcSpatialElement, which also
swallowed IfcSpace. Spaces are legitimate quantifiable objects, so their
Qto_SpaceBaseQuantities (for example GrossFloorArea) were never picked up
and count based cost items fell back to 0. Keep skipping spatial
containers (site, building, storey) but allow IfcSpace.

copy_cost_item appends the copy to the inverse relationships of the
original cost item, which for a root cost item includes the source
schedule's IfcRelAssignsToControl. copy_cost_schedule then assigned that
same cost item to the new schedule as well, so the copies showed up in
both schedules and deleting them from one removed them from the other.
Unassign the copy from the source schedule before assigning it to the
new one.

This reverts commit b61f809731.
This commit was probably using not updated build, currently latest build is e333c1c and can confirm that it has `logger_or_root` added and `delete_same_facet_edge_pairs` removed.
* Keep real cause in wrapper ImportError
When the compiled wrapper exists for the current interpreter but fails
to load (for example a glibc version mismatch, as on AWS Lambda in
issue 5927), the bare except rewrote the error into the misleading
"IfcOpenShell not built for '<platform>'" message. Environments such
as AWS Lambda or the Blender add-on dialog only surface the final
exception message, so the actual cause was invisible and undiagnosable.
Keep the "not built for" message only when no matching binary is
present, and otherwise include the original loader error, chaining the
cause in both branches.
This change was AI-generated.
Fixes#5927
* Simplify wrapper import failure to a single message
Per review feedback, drop the filesystem scan and the two message
variants. Always raise the classic "IfcOpenShell not built for
'<platform>'" message with the original exception appended in
parentheses, still chained as the cause. Environments that only show
the final exception message (AWS Lambda, the Blender add-on dialog)
now surface the real loader error, such as the glibc version mismatch
in issue 5927, without any extra logic.

Both files were merged unformatted and fail the Black formatter step
on every branch, keeping ci-lint red repo-wide.
Generated with the assistance of an AI coding tool.
The ci-lint workflow's ty steps fail on every branch because base
v0.8.0 has four diagnostics.
ty check (bonsai):
- root/operator.py: bpy.data.objects.get() can return None, so
UnlinkObject._execute could put None in its objects list and crash
on the first attribute access when an unknown object name is passed.
Handle the miss explicitly, which also satisfies the declared
list[bpy.types.Object] type.
- tool/sequence.py: ty does not narrow Literal types through
membership tests on list literals, so the assert_never() exhaustive
check was flagged. Use tuple literals, which ty narrows, keeping the
exhaustiveness check intact.
ty check (ios):
- draw.py: arrange_polygons was called through conditional argument
splats that let the same call site work against pre-April-2026
wrappers lacking arrange_polygon_settings and the logger parameter.
No runtime bug for current builds, but the dynamic splats cannot be
typed against the fixed 3-parameter signature. Drop the old-build
workaround and call the current signature directly, following the
precedent of 3d8115ebc5 which dropped similar old-build workarounds
in ifcopenshell.file. Verified against a current wrapper build that
the direct call arranges polygons and serializes to SVG, with and
without a logger.
- Optimise.py: igraph is an optional dependency with a guarded import
and a toposort fallback, but it was missing from the ios type-check
venv so ty could not resolve it. Add it to type-check-requirements
next to the toposort fallback that is already listed.
After this, poe ty-bonsai and poe ty-ios both pass cleanly.

Ran the new sync_stub.py against a real local build: adds
context.delete_same_facet_edge_pairs (present on the compiled wrapper,
missing from the stub) and drops the module-level logger_or_root
(present in the stub, no longer exists on the wrapper at all).
Nothing else changes - no license header rewrite, no docstring loss,
none of the 14 hand-curated named-parameter constructor/function
signatures touched, unlike the wholesale regeneration this replaces.
Generated with the assistance of an AI coding tool.
generate_stub.py (this branch's earlier commit) regenerates
ifcopenshell_wrapper.pyi wholesale from the compiled wrapper: it
reliably fixes real drift, but it also discards everything that isn't
mechanically recoverable from the wrapper alone - the license header,
docstrings, and hand-curated named-parameter signatures for
SWIG-overloaded constructors/functions (SWIG itself always emits
generic `*args` for those, so a regenerator can't tell a deliberate
curation from real drift and just overwrites it).
sync_stub.py takes the smaller-blast-radius approach: it only adds
top-level symbols/class members that are genuinely missing, and only
removes ones that are genuinely gone, cross-checking against
validate_stub.py's own full canonicalisation (via the newly-exposed
get_names_tree()) so it never mistakes a property()/staticmethod()-
wrapped member for something absent just because its own narrower
parser skips that form. Anything that exists on both sides under the
same name but with a different signature - exactly where curation
lives - is left untouched and reported for a human to review instead
of guessed at.
Verified against a real local build: applying it to the current
ifcopenshell_wrapper.pyi produces a small, targeted diff (add one
missing method, drop one stale function) with the license header,
docstrings, and all 14 curated constructor/function signatures
preserved byte-for-byte, versus generate_stub.py's ~1000-line
wholesale rewrite for the same underlying fix.

set_shape_transparency() called AIS_InteractiveContext.SetTransparency(),
whose argument count is inconsistent across pythonocc-core versions
(reported as a TypeError in #1037). Set transparency directly on the AIS
object instead, the same stable pattern already used elsewhere in this
file (display_shape() calls ais.SetTransparency() directly, never through
the Context), then call Context.UpdateCurrentViewer() to refresh.
app.py's viewer used a "SetSelectionPriority(counter)"/"SelectionPriority()"
pair as an ad hoc unique key to map a displayed AIS object back to its IFC
product. On modern pythonocc-core this crashed with AttributeError because
.GetObject() (needed to unwrap the old handle-based API) no longer exists
on AIS objects (#1098, PR #1113 partially patched one of the two call
sites but left the one in HandleSelection unguarded).
Live pythonocc-core 7.9.3 testing showed the GetObject() guard alone is
not sufficient: SetSelectionPriority/SelectionPriority themselves have
been removed from AIS_InteractiveObject entirely in modern OCCT (only
AIS_Trihedron keeps a same-named but unrelated method for datum parts),
so gating the .GetObject() call with the existing USE_OCCT_HANDLE flag
would still crash the first time a shape is selected. Verified live that
AIS objects retain correct __eq__/__hash__ (matching the underlying OCCT
instance) across separate SWIG wrapper instances, so ais_to_product is
now keyed directly by the AIS object itself, removing the dependency on
the removed OCCT API and the GetObject()/handle distinction altogether.
Verified live against pythonocc-core 7.9.3 (conda-forge) using real
AIS_Shape objects obtained from ifcopenshell.geom.occ_utils.display_shape()
and a real IFC file: reproduced both the original TypeError (#1037) and
AttributeError (#1098), confirmed both fixes resolve them, and confirmed
the ais_to_product dict lookup round trips correctly through a real
Context.Select()/SelectedInteractive() call. Could not exercise the full
Qt-embedded viewer.finished()/HandleSelection() flow end to end because
this pythonocc-core build segfaults natively when creating a second GL
context inside a Qt widget on this macOS host, a pre-existing environment
issue unrelated to this diff (reproduces identically with unpatched code,
before any touched line executes).

create_shape() returns a Python-owned Element (SWIG_POINTER_OWN in the
boost::variant out typemap). Its .geometry property calls Element::geometry(),
which returns a reference into the element's boost::shared_ptr<Representation>
_geometry member. SWIG wraps that reference as a non-owning pointer, so the
returned Triangulation/BRep/Serialization proxy does not keep the element alive.
When a caller keeps only .geometry (e.g. create_shape(s, e).geometry) and drops
the parent element, Python garbage-collects the element, destroying its
shared_ptr and freeing the underlying representation. Subsequent reads of
verts/faces then return freed memory: empty or implausible float/int garbage,
non-deterministically depending on GC and allocator timing. This is silent data
corruption, not a crash, and has bitten users since 2020.
Fix: in the TriangulationElement/SerializedElement/BRepElement pythoncode, wrap
the geometry getter so the returned geometry stores a backreference to its
owning element (result._parent = self). This makes the parent's lifetime at
least as long as the geometry's, automatically and transparently, so no caller
has to remember to hold the element. This is aothms's suggested backreference,
applied generically in the binding rather than left as a workaround.
Reproduced deterministically (washBasin fixture): before, verts len 0 vs 133500
across repeated GC-pressure runs; after, 133500 every run for all three element
types. test_create_shape passes; no regressions.
Note: tree.select_ray()'s ray_intersection_result (2024 follow-up in #1124) is a
separate ownership mechanism (std::vector element reference + std::array member
pointer) and is left as follow-up scope.

Two related bugs in read_from_stream's reference-resolution
loop, both reachable from malformed input:
- has_attribute_value<IfcBaseClass*> only checks the stored
slot's type, not that it's non-null (e.g. an explicit $
value), so the following get_attribute_value() call could
return null and inst->declaration() crashed on it.
- byid_[ref] default-inserts (and returns) a null pointer
when the owning instance id isn't present, which was then
dereferenced unconditionally via ->data().
Added regression tests using the two minimized crash inputs
that found these.

`values` dictionary was missing and variables were never collected to it, so `FormulaEvaluator(values)` was always resulting in missing variable error.
The fixture declared FILE_SCHEMA(('IFC2X3')) but used
IFCPROPERTYSETDEFINITIONSET(...), a defined type that only exists in
IFC4+ (confirmed absent from the generated Ifc2x3-schema.cpp/
Ifc2x3-definitions.h, present in the IFC4 equivalents). The file's own
FILE_NAME record ('Column_4x3.ifc') suggests it was originally
exported as IFC4X3 and the schema tag was later miscopied to IFC2X3.
Traced with an instrumented parser build: on encountering the
unrecognized keyword, declaration_by_name() correctly throws
"Entity with name 'IFCPROPERTYSETDEFINITIONSET' not found in schema
'IFC2X3'", caught by the existing IfcException handler in
in_memory_file_storage::load(). The parser then falls back to parsing
the trailing (#136,#138) as a plain nested SET rather than the typed
value, so RelatingPropertyDefinition ends up as a bare tuple instead
of an IfcPropertySetDefinitionSet-wrapped value with .is_a(). This is
correct, expected behavior for content that doesn't match its
declared schema - not a parser bug. Fixing the header to IFC4 (which
does declare the type) resolves test_stream, test_file, and test_rocks
in test_streaming_rocksdb_and_simpletyperefs.py.

The class-pairing validation added in 10ee5aef4f rejects any type
assignment whose class isn't in the buildingSMART implementer
agreement map. That map only covers physical product occurrence/type
pairs (IfcWallType -> IfcWall, etc); IfcTypeProcess and IfcTypeResource
subtypes such as IfcTaskType, IfcProcedureType and the resource types
have no entry, so previously-valid assignments like
IfcTaskType -> IfcTask were rejected with "allowed occurrence
classes: <none>".
These classes still follow the schema's universal Type-suffix naming
convention, so derive the pairing the same way the existing
ApplicableOccurrence fallback does: strip "Type" from the relating
type's class name and accept it only if the schema actually declares
that entity. This can only add pairings implied by the type's own
class name, so it cannot loosen the existing rejection of genuine
mismatches (e.g. IfcWallType -> IfcWindow).

Add svg-use-edge-classification (default off, preserving today's
linework), svg-render-crease-edges, and svg-render-sharp-edges
settings, gating the existing 5-class classification feature so it
can be disabled entirely (falling back to the pre-classification
whole-shape output) or have individual classes suppressed.
Also fixes a bug uncovered while wiring this into Bonsai: ready(),
where geometry_settings() actually gets read into the serializer,
was only ever invoked explicitly by IfcConvert's CLI driver and
isn't exposed to Python. Every Svg* setting -- including the three
from previous rounds -- silently stayed at its hardcoded constructor
default when the serializer was constructed directly through the
Python bindings, as Bonsai does. Fixed by calling ready() from
SvgSerializer's own constructor, safe since it only reads
geometry_settings() with no other side effects, and settings are
always finalized before construction in every call path.
