# ArrayBox get/set -> Invalid arguments (plugin side)
|
|
|
|
Status: open
|
|
|
|
Summary
|
|
|
|
- Error messages observed during AOT/LLVM smoke that touches ArrayBox:
|
|
- "Plugin invoke error: ArrayBox.set -> Invalid arguments"
|
|
- "Plugin invoke error: ArrayBox.get -> Invalid arguments"
|
|
- VInvoke(MapBox) path is stable; issue is isolated to ArrayBox plugin invocation.
|
|
|
|
Environment
|
|
|
|
- LLVM 18 / inkwell 0.5.0 (llvm18-0)
|
|
- nyash-rust with Phase 11.2 lowering
|
|
- tools/llvm_smoke.sh (Array smoke is gated via NYASH_LLVM_ARRAY_SMOKE=1)
|
|
|
|
Repro
|
|
|
|
1) Enable array smoke explicitly:
|
|
- `NYASH_LLVM_ARRAY_SMOKE=1 ./tools/llvm_smoke.sh release`
|
|
2) Observe plugin-side errors for ArrayBox.get/set.
|
|
|
|
Expected
|
|
|
|
- Array get/set should be routed to NyRT safety shims (`nyash_array_get_h/set_h`) with handle + index/value semantics that match the core VM.
|
|
|
|
Observed
|
|
|
|
- Plugin path is taken for ArrayBox.get/set and the plugin rejects arguments as invalid.
|
|
|
|
Notes / Hypothesis
|
|
|
|
- LLVM lowering is intended to map ArrayBox.get/set to NyRT shims. The plugin path should not be engaged for array core operations.
|
|
- If by-name fallback occurs (NYASH_LLVM_ALLOW_BY_NAME=1), the array methods might route to plugin-by-name with i64-only ABI and mismatched TLV types (index/value encoding).
|
|
|
|
Plan
|
|
|
|
1) Confirm lowering branch for BoxCall(ArrayBox.get/set) always selects NyRT shims under LLVM, regardless of by-name flag.
|
|
2) If by-name fallback is unavoidable in current scenario, ensure integer index/value are encoded/tagged correctly (tag=3 for i64) and receiver is a handle.
|
|
3) Add a targeted smoke (OFF by default) that calls only `get/set/length` and prints deterministic result.
|
|
4) Optional: Add debug env `NYASH_PLUGIN_TLV_DUMP=1` to print decoded TLV for failing invokes to speed diagnosis.
|
|
|
|
Workarounds
|
|
|
|
- Keep `NYASH_LLVM_ARRAY_SMOKE=0` in CI until fixed.
