face_grid leaked both buffers when the kernel threw mid-grid, and tess copied every mesh array a second time. Also drop the stale S5 references.

OCP.STEPControl — STEP read and write.
|
|
|
|
The reader inherits its transfer surface from XSControl_Reader; what is
|
|
added here is the unit handling the app needs (FileUnits reports what the
|
|
file declares, SetSystemLengthUnit rescales the transfer) and ReadStream,
|
|
which takes a Python file-like.
|
|
|
|
ReadStream reuses the slurp bridge from occt_stream.h rather than wrapping
|
|
a streambuf that calls back into Python — same reasoning as BinTools, and
|
|
the same one extra copy.
|
|
|
|
The GIL stays held throughout, per the note in mod_XSControl.cpp: XSTEP is
|
|
built on process-global state and the app serialises imports anyway.
|
|
|
|
The wheel ships none of OCCT's share/ resources; STEP still resolves units
|
|
in a container with no CSF_* environment, which tests/test_inc3_io.py pins.
