结论：按 LinuxCNC src/emc/rs274ngc/interp_base.cc 的 dlopen/dlsym/dlerror 调用点，补强 WASM dlfcn shim 与 interp_base probe，确认浏览器安全探针中动态加载保持不可用；不扩展 smoke 解析。

LinuxCNC WASM shims source map
This map records the source basis for the C++ sources in the
CMake linuxcnc_wasm_safe_probe_shims set. It is a build/source-link guard
only; it must not add CNC behavior and must not expand the temporary smoke parser.
Generated Coverage
| Output | Count | Source coverage role |
|---|---|---|
CMake linuxcnc_wasm_safe_probe_shims sources |
11 | Browser-safe LinuxCNC adaptation shims linked into WASM source probes. |
Shim Map
| Shim | LinuxCNC source basis | Boundary |
|---|---|---|
core/wasm_shims/dlfcn.cc |
src/emc/rs274ngc/interp_base.cc |
Satisfies native dlopen symbols for browser-safe probes while keeping dynamic loading unavailable. |
core/wasm_shims/emc_status_shim.cc |
src/emc/sai/dummyemcstat.cc |
Provides the source-backed emcStatus singleton shape without task/NML startup. |
core/wasm_shims/gettext_shim.cc |
src/emc/rs274ngc/interp_internal.hh |
Preserves LinuxCNC diagnostic call sites without browser gettext catalogs. |
core/wasm_shims/linuxcnc_runtime_shim.cc |
src/emc/rs274ngc/gcodemodule.cc, src/emc/task/emctaskmain.cc, src/emc/task/taskclass.cc, src/emc/rs274ngc/interp_namedparams.cc, src/hal/hal_lib.c, src/emc/rs274ngc/rs274ngc_pre.cc |
Keeps preview/task, builtin Python module, HAL lookup, and wordexp() edges compile-safe. |
core/wasm_shims/nml_status_shim.cc |
src/libnml/nml/nmlmsg.cc, src/libnml/nml/stat_msg.cc |
Provides NML status constructors needed by source-linked EMC status objects. |
core/wasm_shims/python_c_api_shim.cc |
src/emc/rs274ngc/interp_python.cc, src/emc/rs274ngc/interp_namedparams.cc, src/emc/rs274ngc/gcodemodule.cc, src/emc/pythonplugin/python_plugin.cc |
Satisfies Python C API symbols while Python/Boost.Python remap paths remain tracked blockers. |
core/wasm_shims/rcs_print_shim.cc |
src/libnml/rcs/rcs_print.cc |
Provides LinuxCNC RCS print diagnostics used by NML validation. |
core/wasm_shims/rtapi_compat.cc |
src/rtapi/uspace_common.h, src/rtapi/rtapi.h |
Provides userspace RTAPI formatting declarations used by RS274/NML code. |
core/wasm_shims/tooldata/tooldata_mmap_backend.cc |
src/emc/tooldata/tooldata_mmap.cc |
Replaces native mmap storage with an in-memory WASM-safe backend for probes. |
core/wasm_shims/tooldata/tooldata_runtime_stubs.cc |
src/emc/tooldata/tooldata_nml.cc, src/emc/tooldata/tooldata_db.cc |
Satisfies NML and external tool database entry points without native services, preserving inactive-DB return values. |
core/wasm_shims/pythonplugin/python_plugin.cc |
src/emc/pythonplugin/python_plugin.cc, src/emc/pythonplugin/python_plugin.hh |
Keeps LinuxCNC PythonPlugin API and negative-status short-circuit behavior available while Python execution is disabled for browser-safe probes. |
Boundaries
- The CMake
linuxcnc_wasm_safe_probe_shimsset andlist-linuxcnc-wasm-safe-shims.shmust stay synchronized. - Each shim source must keep a nearby
LinuxCNC source basis:comment naming the LinuxCNC source it adapts. - Every LinuxCNC source named above must remain tracked in the RS274/WASM manifest as
core,header, ormetadata. - These shims are browser-safe LinuxCNC adaptations for source-link probes; they are not new interpreter behavior.
Checks
Run:
./check-linuxcnc-wasm-shims-source-map.sh
./test-linuxcnc-wasm-cmake-safe-probe.sh
./test-native.sh
./test-linuxcnc-source-link.sh
check-linuxcnc-wasm-shims-source-map.sh keeps this document, the CMake shim
set, list-linuxcnc-wasm-safe-shims.sh, LinuxCNC source anchors, and the
RS274/WASM manifest synchronized.
