`START` is set to `0` for "amd64" / "x64" and `1` in all other cases, effectively just skipping `GENERATORS[0]` in case when "amd64" or "x64" is present.
Which is now useless, since `GENERATORS[0]` doesn't exist anymore.
They were added awhile ago in 67666ed for overcoming some win32 issues, which is not around anymore.
And now `VS_HOST` is never set (and therefore `VS_TOOLSET_HOST` is always empty too) and likely to be never used.
CI was failing:
```
The system library `dbus-1` required by crate `libdbus-sys` was not found.
The file `dbus-1.pc` needs to be installed and the PKG_CONFIG_PATH environment variable must contain its parent directory.
The PKG_CONFIG_PATH environment variable is not set.
```
There was an error building a standalone ifcwrap when previously built IfcOpenShell had rocksdb - `_ifcopenshell_wrapper.cpython-314-x86_64-linux-gnu.so: undefined symbol: _ZTV17RocksDbSerializer`.
`IFOPSH_WITH_ROCKSDB` propagated to the build, requiring rocksdb symbols, but `WITH_ROCKSDB` wasn't set and `document_serializer_rdb` target wasn't provided.
Otherwise it will never be able to reach standalone ifcwrap build as in this case ifcopenshell is built first as a dependency without `BUILD_IFCPYTHON`.
When fixing warnings, noticed that was working a bit inproperly - `bnode` always end up being an empty list (because there's no `brick, A, REF.IFCReference` triple), so then passing empty list to `triples` resulted in selecting all nodes isntead of just the expected `bnode` (that's the behaviour `sqlachemy` was sending the warnings about - when empty lists unexpectedly selected everything).
`None, None` assumed by default.
Though this was introduced in Python 3.13, before 3.13 it only breaks if we'd do `typing.Generator[T]` (which is deprecated) -`collections.abc.Generator[T]` works fine, it seems it never had an arity check.
Raising `AttributeError` is definitely wasn't correct here, since it
might push the code to assume it's a wrong entity type. Returning some stub value like `None` also could suggest incorrect derived attribute
value, leading to unexpected behaviour. So adding an error, so it would
propagate and code would need to be adjusted not to rely on derived
attributes, if it actually interacts with sql/stream.
`test_unit` was asserting that derived attr will return `None`, though
it was actually raising `AttributeError`.
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'.
