# Lua module validation
|
|
|
|
Local implementation checks, 2026-09-18. These results supplement, not replace,
|
|
the earlier MVP acceptance record. Toolchain: Linux x86-64, GCC 13.3, CMake 4.4.3,
|
|
Ninja 1.13.2; pinned Lua 5.4.9.
|
|
|
|
## Observed results
|
|
|
|
| Configuration | Result |
|
|
|---|---|
|
|
| Lua enabled, renderer/editor UI disabled | 20/20 CTest tests passed |
|
|
| Lua disabled, renderer/editor UI disabled | 18/18 CTest tests passed |
|
|
| AddressSanitizer + UndefinedBehaviorSanitizer, Lua suites | 3/3 tests passed |
|
|
| Renderer-linked native Player and SchemaExporter | Built successfully; CPU Lua CLI contracts passed |
|
|
| Lua-only project without project C++ files | Empty native adapter built; sample validated; exactly two Lua schemas exported |
|
|
| Native Editor and Editor UI library | Compiled and linked; Editor `--help` ran |
|
|
| Manual | MkDocs strict build passed |
|
|
|
|
The Lua tests exercise lifecycle ordering, per-instance fields/state, VM ownership,
|
|
stale/cross-world handles, deferred structural operations, native physics contacts,
|
|
`require`, invalid schemas, CPU/memory limits and the shipped example scene. Additional
|
|
safety cases cover deep/cyclic JSON, repeated-string/key expansion, structural queue
|
|
limits, protected metatables, repeated OOM and reclamation of a failing instance.
|
|
|
|
BuildService tests exercise source snapshots, fingerprints, changes during a build,
|
|
Lua-only projects, export contents/notices, and switching back to Lua-free games.
|
|
Their native build/export fixture is a stand-in, not a graphical Player execution.
|
|
|
|
## Reproduce the CPU suite
|
|
|
|
```sh
|
|
cmake -S . -B build/lua-check -G Ninja -DCMAKE_BUILD_TYPE=Debug \
|
|
-DFASET_ENABLE_LUA=ON -DFASET_BUILD_RENDERER=OFF -DFASET_BUILD_EDITOR=OFF
|
|
cmake --build build/lua-check --parallel
|
|
ctest --test-dir build/lua-check --output-on-failure
|
|
```
|
|
|
|
Use a separate build directory with `-DFASET_ENABLE_LUA=OFF` for the optional-module
|
|
check. For sanitizers, configure with `-DFASET_SANITIZERS=ON`, build the
|
|
`faset_lua_tests`, `faset_lua_safety_tests`, and `faset_schema_exporter` targets, then
|
|
run `ctest --test-dir <build> --output-on-failure -R '^lua_'`.
|
|
|
|
## Not verified in the September 18 run
|
|
|
|
- Windows compilation or execution of the new module.
|
|
- Graphical/window interaction and real-time Lua reload in a running rendered game.
|
|
`lua_player_reload` is provided as a GPU-labelled integration test for an equipped host.
|
|
- A complete real Release export launched on a separate machine.
|
|
- LeakSanitizer: this execution environment uses tracing incompatible with its
|
|
process inspection, so sanitizer runs used `ASAN_OPTIONS=detect_leaks=0` and
|
|
`UBSAN_OPTIONS=halt_on_error=1`. Address/undefined-behavior checks stayed enabled.
|
|
|
|
The renderer-linked CPU checks used the existing Vulkan loader, repo-pinned Vulkan
|
|
headers and cached Slang, with SDL X11/Wayland disabled. No system graphics packages
|
|
were installed. This proves linkage and CPU validation, not graphics compatibility.
|
|
|
|
## September 24 Release follow-up
|
|
|
|
The [Release execution record](lua-release-2026-09-24/README.md) closes the
|
|
Linux offscreen export gap above. At source commit `4331857`, a Release Editor
|
|
exported the checked-in Lua-only sample into a disposable Unicode-path project.
|
|
The package was relocated, the source project path was hidden, and its Player
|
|
validated and rendered 120 frames on an NVIDIA GeForce RTX 2080 Ti with driver
|
|
595.84 and Khronos validation enabled; zero validation errors were reported.
|
|
The package manifest has `lua_enabled: true`, declared Lua source and its license,
|
|
and no project C++ gameplay source. The five focused Release Lua/schema tests
|
|
passed. This verifies an offscreen run on Linux; a separate physical Windows GPU
|
|
and manual window interaction have not been tested by this record. Windows
|
|
SwiftShader execution is configured in CI and needs a passing run before it is
|
|
claimed as covered.
