Using symlinks just for main libs/pluigins doesn't seems to resolve `$ORIGIN` for some reason - e.g. occt libraries appears to be missing. So symlinking everything, including the dependencies seems to be the way to create a dev environment.
Facet.filter() implementations broad-phase query with
ifc_file.by_type(), then check isinstance(elements, list) to decide
whether a previous facet already narrowed the candidate set. In
v0.9.0, file.by_type() returns a tuple instead of a list, so that
check silently failed and every facet after the first re-scanned the
whole model instead of the already-narrowed (possibly empty) set.
This let a prohibited Entity+Attribute applicability match instances
of the wrong class, e.g. an IfcSlab satisfying an "IFCWALL" Entity
facet's chain. Accept tuples too, matching how by_type() results are
actually returned now.
get_attribute_category() returns 3 for a derived attribute, but
sqlite_entity.__getattr__() only branched on FORWARD (1) and INVERSE
(2), so any derived attribute (e.g. IfcSIUnit.Dimensions) fell
through to the final AttributeError instead of returning None, which
is what SQLite-linked files are documented to do since derived
attributes are not computed for them. Mirrors the DERIVED handling
already present in entity_instance.py's __getattr__.
diff() looked up common elements with self.old.by_id(global_id) /
self.new.by_id(global_id), passing a GlobalId string into a method
that expects a STEP integer id. On v0.8.0 file.by_id() was a Python
wrapper that transparently dispatched strings to by_guid(), so the
bug was silent. v0.9.0's file class binds by_id directly to the
C++ instance_by_id(int), so it now raises
TypeError: in method 'file_by_id', argument 2 of type 'int'.
Runtime plugins are canonically named `ifcopenshell_<kind>_<name>` (decorated_basename() in src/plugin/plugin.cpp, and the OUTPUT_NAME properties of the plugin targets), but the archive collection filtered on the dotted `ifcopenshell.` prefix, which matches only the core shared libraries. Every load-by-name plugin was therefore silently dropped from every win64 / win-arm64 zip.
Accept both prefixes, and extend the geometry-writer exclusion to the underscore form so the per-schema writers keep their existing Python-package-only treatment.
Fixes#9301
* Honour IfcAxis2PlacementLinear Axis/RefDirection in the loft builder
make_loft() (src/ifcgeom/infra_sweep_helper.cpp), shared by
IfcSectionedSolidHorizontal and IfcSectionedSurface, mishandled a cross
section's IfcAxis2PlacementLinear in two ways:
1. A placement carrying Axis but no RefDirection was placed with a fixed
[e_y | e_z | e_x] world-axis permutation that ignored the directrix.
On any directrix not running along +X (e.g. a north-south road
pavement, or anywhere along a curve) the profile came out mis-oriented
or collapsed to a sliver.
2. When two adjacent CrossSectionPositions used direction vectors
inconsistently (a raked RefDirection at one, a plain Axis at the
other) make_loft() logged GEO 42, dropped the rotation for the whole
segment and squared every cap -- and in one configuration left the
sweep frame flipped, so OpenCASCADE failed to build the solid at all.
Now a small profile_basis() helper builds every cross section's frame the
same way: profile Y = Axis, profile normal = RefDirection, and -- when
RefDirection is absent -- profile normal = the directrix tangent, so the
section stays perpendicular to the path (buildingSMART IFC4.x-IF #147).
When the two bracketing placements ask for the same orientation the sweep
frame carries it, built against the curve. When they disagree the sweep
frame stays on the shared Axis (continuous with the neighbouring
consistent segments, so nothing flips) and each end's own authored
orientation is folded into its profile points via a change of basis, so
each end cap still lands exactly as authored while the body in between
keeps following the directrix. The all-equal and no-direction-vector
paths are unchanged.
The two mappings now also carry the raw RefDirection through on
cross_section, alongside the existing rotation matrix.
Adds C++ tests (a raked end logs no GEO 42; a directrix that does not run
along +X still lofts a full-size solid) and Python tests (uniform prism
raked at one end and square at the other; a north-south directrix keeps
its width; OffsetLateral/OffsetVertical are scaled by the model length
unit).
* Renames profile_rotations to profile_axis for consistency with profile_ref_directions
Adopt the reviewer's suggestion on #9396: instead of counting how many
skips each duplicate identity has earned, record which duplicate
identities have already built once. The first occurrence builds, the
rest are skipped. Distinct-identity loops that only become duplicates
after point mapping behave as before. Set semantics are also robust if
the helper is ever driven over the same shell twice, where a consumed
counter would under-build.
Port of #8772 to v0.9.0 (open_cascade_kernel::faceset_helper is the
renamed class, same logic). When an IfcConnectedFaceSet repeats the
same IfcFace, wires() still dropped every occurrence via duplicates_,
leaving a hole in the shell; this counts the redundant occurrences
and skips only those, keeping one copy of each repeated face.
ifcopenshell.geom.create_shape constructs a geometry kernel, converter and
mapping on every call and discards them afterwards. For hybrid kernels the
construction alone rescans the plugin directory per component, which #9417
addresses on the C++ side by caching the resolved component ids. This
prototypes the alternative aothms suggested in the #9417 review: reuse the
constructed kernel itself from Python.
The wrapper gains a geometry_kernel class holding the converter (and through
it the kernel, mapping and conversion caches) built once per
(geometry_library, file, settings) triple, with create_shape(instance[,
representation]) delegating to the same helper the free create_shape uses,
now split so both paths share one body. Python gains
ifcopenshell.geom.kernel(settings, file, geometry_library) mirroring the
iterator constructor signature. The binding is fixed at construction:
settings are copied the way converter already copies them, and a guard
rejects instances from a different file because the mapping is file-bound.
On PGSuper_Import_Model.ifc (322 products, single-threaded, arm64 Linux),
hybrid-cgal-simple-opencascade drops from 71.97 ms/call with per-call
create_shape to 23.35 ms/call through the reused kernel, matching the
iterator (22.74 ms/call) without needing the #9417 cache; plain opencascade
is unaffected (23.30 vs 22.28 ms/call).
Constructing a hybrid kernel (e.g. hybrid-cgal-simple-opencascade) ran
find_kernel_match once per component on every construction. Each call
creates a plugin manager, walks the plugin search paths and loads every
geometry_kernel_* module from disk before matching the component name.
Named kernels only pay this once because they are registered in the
static registry after the first load, but a hybrid name is never
registered, so every iterator or create_shape construction repeated the
full scan (measured 28-100 ms per component on the reference model,
~70 ms extra per create_shape call; far worse on platforms where
library loading is expensive).
Cache the resolved component backend ids per hybrid name. The first
construction still performs the full discovery and registers the
matched modules; subsequent constructions build the components straight
from the registry without touching the disk.
`BOOST_VERSION_UNDERSCORE` unused since 2e35b07
`OCE_LOCATION` is dead since it was introduced 72d8b5377 (and was a dead variable in build-all.sh too)
`curl`, `wget` - replaced with `urlretrieve back in 51cf52c38
Moved `BOOST_LOCATION` next to its `build_dependency`, so it will have a harder time getting lost.
Follow-up to cb08191. The comma-separated pset value was resolved by
tool.Ifc.resolve_uri() as a single path before add_stylesheet() split it,
so normpath collapsed the whole string down to the last entry.
Split the value into paths first, then resolve each one, and concatenate
the stylesheets in listed order into a single <style> element.

Example error coming from Linux build (`build_rocky` is bringing ISU dev libs transitively through pango/cairo):
```
./BonsaiViewer: error while loading shared libraries: libicudata.so.67: cannot open shared object file: No such file or directory
```
As it installs everything to `lib`, making it hard to filter things that are needed just for Python wrapper (e.g. skipping qt libs). Anyway we deploy everything ourselves manually in `package-zip-archives`.
set_attribute_value_py turned every Python None into blank{}, so
createIfcSIUnit(None, ...) stored a null in the derived Dimensions slot.
The STEP output still shows "*" and the Python accessor still resolves
the value, but validate() reads the raw slot and reports "Attribute is
derived in subtype" for every such instance. 0.8.5 accepted the same
call and kept the derived marker. Mirror populate_derived_() and store
derived{} when the target slot is derived.
get_special_type_for_prop() reached the declaration through
entity.wrapped_data, which v0.9.0 removed when entity instances started
inheriting from the wrapper type directly. Ten ci-bonsai-daily tests
fail on it (quantification, pset editing, templated quantities). Use the
declaration property the way entity_instance.is_entity() itself does.
v0.9.0 already carries the ifcopenshell::file rename this harness was
originally adapted for, but moved Logger into the ifcopenshell namespace
too (logger::root() -> ifcopenshell::logger::root()) and never had a
BUILD_ONLY_COMMON_SCHEMAS cmake option - schema selection there has always
been via the SCHEMA_VERSIONS list. Verified with -fsyntax-only against the
system-installed v0.9.0 headers.
Logger::SetOutput was never called by the harness, so every parse
warning/error (e.g. "Overwriting instance with name #N") was silently
discarded. This directly cost time root-causing a leak: grepping stdout
for an expected warning found nothing, looking like it ruled out a
hypothesis that was actually correct, because the message was just never
printed anywhere.
Only enable it when the binary is given an explicit file argument
(single-input repro, e.g. `-runs=1 <file>`), not during a real campaign
against a corpus directory, where logging on every execution would
dominate the runtime. Verified with -fsyntax-only against this branch's
headers (a real CMake build of ifcviewer-wgpu wasn't attempted, same as
the harness's prior namespace-rename commit).
Generated with the assistance of an AI coding tool.

ifcviewer-wgpu renamed IfcParse::IfcFile to ifcopenshell::file (header
moved to ifcparse/file.h) and Base::toString to Base::to_string. Update
the harness and README to match; verified with a syntax-only compile
against this branch's headers.
Construction of IfcFile already tokenizes, type-checks, and resolves
every attribute of every instance, so toString() isn't what makes
tokenizer/argument bugs reachable.
A coverage-guided libFuzzer harness (src/ifcfuzz/ifcparse_fuzzer.cpp) that
constructs IfcFile directly from in-memory input and calls toString() on
every parsed instance to force full lazy attribute evaluation, rather than
only observing IfcConvert's exit code from a fuzzed subprocess.
Gated behind a new BUILD_FUZZERS option (OFF by default) so it has no
effect on existing builds; enabling it requires a Clang toolchain built
with -fsanitize=fuzzer. -fsanitize=fuzzer itself stays scoped to the one
new target rather than going into the global compiler flags, since it
supplies its own main() and would otherwise break every other target
including CMake's own compiler checks.
Already found and fixed three real bugs this way: two null-pointer
dereferences (in header parsing and reference resolution) and a leak of
IfcSpfLexer on early return/exception during file scanning.
See src/ifcfuzz/README.md for build and usage instructions.
