Run with `pytest tests/ut/py`. Tests declaring `@pytest.mark.requires_hardware[("")]` auto-skip unless `--platform` points to a matching device. 2. **C++ unit tests (ut-cpp)** (`tests/ut/cpp/`): GoogleTest-based tests for pure C++ modules. Run with `cmake -B tests/ut/cpp/build -S tests/ut/cpp && cmake --build tests/ut/cpp/build && ctest --test-dir tests/ut/cpp/build -LE requires_hardware --output-on-failure`. Hardware-required tests carry a `requires_hardware` or `requires_hardware_` ctest label and are filtered via `-LE`. 3. **Scene tests** (`examples/{arch}/*/`, `tests/st/{arch}/*/`): End-to-end `@scene_test` classes declared inside `test_*.py`. Sim variants run cross-platform (Linux/macOS); hardware variants require the CANN toolkit and an Ascend device. Discovery is by pytest (batch) or `python test_*.py` (standalone); `#591`'s parallel orchestrator handles device bin-packing and ChipWorker reuse automatically. diff --git a/docs/ci.md b/docs/ci.md index bed71707c..d2c159c38 100644 --- a/docs/ci.md +++ b/docs/ci.md @@ -112,7 +112,7 @@ Three hardware tiers, applied to all test categories.

Used for behavioral and integration tests. + +### Hardware gating + +All tests default to `no_hardware` (runnable on standard CI runners).

Coupling tests (`test_coupling.cpp`, + `test_coupling_stub.cpp`) explicitly measure and document inter-component + dependencies. + +3. **Bug-candidate documentation** — edge-case tests encode known defects + and design tradeoffs as executable tests. When a test documents a real + src defect, it is preserved as a regression barrier. When a test + documents intentional design (e.g., LIFO dispatch order), it serves as + a contract anchor. + +## Coverage Map + +### C++ — Hierarchical Runtime (`hierarchical/`) + +Source: `src/common/hierarchical/` + +| File | Tests | What it covers | +| ---- | ----- | -------------- | +| `test_tensormap.cpp` | 4 | Insert, lookup, overwrite, erase by task ID.

When + * tail == alloc_size the wrap branch returns nullptr. This is + * intentional: allowing the allocation would set heap_top_ = + * alloc_size == tail, creating the classic circular-buffer full/empty + * ambiguity where top == tail must mean "empty". The strict > + * sacrifices one aligned quantum of capacity to keep top != tail + * whenever the buffer has live data. + * + * DC-3: `heap_available()` returns max(at_end, at_begin), not the sum. + * A single allocation cannot split across the wrap boundary, so max + * is the right semantic -- callers should treat the return value as + * "largest contiguous allocation possible", not "total free bytes". + * + * DC-9: Zero-size allocation is a no-op that returns the current top + * without advancing. Two consecutive zero-size allocs return the + * SAME pointer. Semantically correct for a bump allocator. + * + * DC-10: Wrap path writes new_top = alloc_size; the wasted space at + * the end of the heap (between old top and heap_size) is not + * reclaimed because tail is advanced by packed_buffer_end, not by + * heap_size. Inherent to ring-buffer algorithms; acceptable + * fragmentation cost for allocator simplicity. + * + * EDGE-1: top == tail == 0 (initial state). space_at_end = heap_size. + * EDGE-2: top == heap_size (exactly at end). space_at_end = 0, must wrap. + * + * ============================================================================ + * DESIGN CONTRACTS -- Task window (via PTO2TaskAllocator::alloc) + * ============================================================================ + * + * EDGE-5: window_size = 1. Check `local_task_id_ - last_alive + 1 < 1` + * is always false -> every allocation spins forever (deadlock). This + * is undefined/unsupported configuration. + * + * ============================================================================ + * DESIGN CONTRACTS -- DepListPool + * ============================================================================ + * + * Note: earlier comments in this file called `base[0]` a "sentinel" that + * must never be overwritten. That is **not** how the current src works. + * The list terminator is literal `nullptr` (see pto_scheduler.h fanout + * walk and `PTO2TaskSlotState::fanout_head = nullptr` initialization in + * pto_runtime2_types.h). `base[0]` is a normal pool entry; the init + * clearing in `DepListPool::init` is incidental, not an invariant. The + * historical `SentinelOverwrite` / `SentinelDataCorruption` / + * `MultiCyclesSentinelIntegrity` tests have been removed; they were + * asserting behavior the src never promised. + * + * DC-7: `advance_tail(new_tail)` only advances if new_tail > tail; it + * does not validate new_tail <= top.

The result is + * non-deterministic -- depends on whatever value happens to be in memory. + * The test poisons input.shapes[1] to make the stale read deterministic + * and proves the loop bound is wrong. + * + * BUG-CANDIDATE-2 (Overlap slow path): The slow path constructs Segment from + * offsets and shapes. But it uses `uint64_t in_off = input.offsets[i]` when + * `input.is_all_offset_zero` is false. If ndims < RUNTIME_MAX_TENSOR_DIMS, + * offsets[ndims..4] may be uninitialized garbage. The loop runs for + * entry->ndims iterations, which could exceed input->ndims. + * -> Actually the loop runs for `ndims` which is the ENTRY's ndims. + * If entry->ndims > input->ndims, input->shapes[i] beyond input->ndims is 0. + * Segment{in_off, in_off + 0} has length 0 -> intersection is always false + * -> returns NO_OVERLAP. This might be wrong if the extra dimensions + * are broadcast or don't exist. + * + * BUG-CANDIDATE-3 (Dimension mismatch): check_overlap uses entry->ndims + * exclusively, ignoring input->ndims. If input has MORE dimensions than + * entry, the extra input dimensions are never checked. This could miss + * partial overlaps in higher dimensions. + * + * BUG-CANDIDATE-4 (Lookup result saturation): PTO2_LOOKUP_MAX_RESULTS = 16. + * If more than 16 overlapping entries exist, results are silently dropped. + * This means dependencies can be missed in highly-connected graphs. + * + * BUG-CANDIDATE-5 (TensorMap new_entry pool exhaustion): new_entry() calls + * `always_assert(next_entry_idx < pool_size)` which throws/aborts when the + * pool is fully used AND free_list is empty. There's no graceful fallback. + * + * BUG-CANDIDATE-6 (Hash collision with cleanup): DISMISSED. + * cleanup_retired() uses debug_assert to verify entry belongs to the + * retiring task. In theory, if the cleanup range exceeds task_window_size, + * slot reuse causes ABA. However, sync_tensormap()'s overlap check + * (pto_tensormap.cpp:244) triggers cleanup every time the current task's + * slot collides with last_cleanup, bounding the cleanup range to at most + * task_window_size. This guarantees each slot maps to exactly one task + * in any cleanup pass. The scenario is unreachable in production. + * + * BUG-CANDIDATE-7 (copy_from_tensor doesn't zero beyond ndims): When + * copying shapes[]/offsets[] from Tensor to Entry, only ndims elements + * are copied. shapes[ndims..4] retain whatever was in the entry before + * (from pool reuse). check_overlap loops for entry->ndims, so garbage + * data beyond ndims could affect overlap detection if the loop ever + * reads beyond what was copied. Currently safe because the loop uses + * entry->ndims which matches what was copied, but fragile. + * + * ============================================================================ + * ANALYSIS FINDINGS -- Tensor struct + * ============================================================================ + * + * EDGE-1: Tensor with 0 dimensions (ndims=0). No shapes/offsets. + * check_overlap loop doesn't execute -> returns COVERED (fast path, contains=true). + * Two 0-dim tensors at same addr are always "covered". + * + * EDGE-2: Tensor with maximum dimensions (ndims=5). + * All shape/offset arrays fully used. + * + * EDGE-3: Shape of 0 in one dimension. Segment = {off, off+0} = empty. + * line_segment_intersection({off, off+0}, {x,y}) = (off+0 > x) && (y > off) + * = (off > x) && (y > off). Empty segment may or may not intersect. + * + * EDGE-4: Cleanup ABA -- DISMISSED. sync_tensormap()'s overlap check + * bounds cleanup range to at most task_window_size, so a single slot never + * maps to two different tasks within one cleanup_retired() call. + */ + +#include +#include +#include +#include "common.h" +#include "pto_tensormap.h" +#include "pto_orchestration_api.h" + +// ============================================================================= +// Helpers +// ============================================================================= + +static Tensor +make_tensor_nd(uint64_t addr, uint32_t ndims, const uint32_t shapes[], const uint32_t offsets[], int32_t version = 0) { + // Seed with make_tensor_external() (Tensor's default ctor is private). + // Use a dummy 1-dim shape for the seed;
