The canonical machine type is exposed under an `emel::io::::sm` namespace path with + additive top-level aliases where appropriate. +3. The I/O module documentation and source comments state that I/O owns strategy boundaries and + transport/staging concerns, not tensor residency lifecycle semantics. +4. The milestone introduces no concrete mmap, read/copy, staged, chunked, device-specific, or async + strategy implementation. + +### Phase 198: Tensor-To-I/O Event Contract + +**Goal:** Define the public tensor-to-I/O contract so tensor-owned loading can request I/O work and +receive deterministic success or failure outcomes without hidden shared state. + +**Requirements:** IO-03, TBOUND-01, TBOUND-02 + +**Success criteria:** +1. Tensor-to-I/O request payloads use explicit required references and small immutable public event + fields, with optional pointers only where the ABI or nullability rules require them. +2. I/O success and failure outcomes use explicit `_done` and `_error` events or states rather than + mirrored status fields, dispatch-local context, or action-selected callbacks. +3. `model/tensor` can target the I/O boundary through public event interfaces while remaining the + residency lifecycle owner. +4. Unit tests drive the contract through `process_event(...)` and SML state inspection rather than + reaching into actor actions or detail helpers. + +### Phase 199: Strategy Policy Boundary + +**Goal:** Establish how strategy policy is injected and how strategy availability is selected in +the transition graph while keeping this milestone strategy-framework-only. + +**Requirements:** TBOUND-03, POLICY-01, POLICY-02, POLICY-03 + +**Success criteria:** +1. Runtime strategy availability and rejection paths are represented by guards, choice states, and + destination-first transition rows in `sm.hpp`. +2. Actions and detail helpers do not branch on strategy kind, backend support, file layout, or + fallback choice to decide which behavior runs next. +3. The no-concrete-strategy path fails deterministically and preserves existing tensor residency + behavior. +4. The contract can admit future mmap and staged/copy strategy actors without changing tensor + residency ownership or adding queues, deferred events, or asynchronous scheduling now. + +### Phase 200: Loader And Maintained Lane Integration + +**Goal:** Keep `model/loader` and maintained tools at the orchestration layer while aligning their +loading flow with the public tensor-to-I/O boundary shape. + +**Requirements:** LOAD-01, LOAD-02 + +**Success criteria:** +1. `model/loader` does not include or implement backend-specific byte access, mapping, staging, or + loading strategy loops. +2. Maintained GGUF loader, benchmark, paritychecker, and embedded probe entrypoints continue to use + public runtime surfaces and do not include actor `actions.hpp`, `detail.hpp`, or `detail.cpp` + internals from loader, tensor, or I/O components. +3. Existing maintained model-loading behavior is preserved unless a change is explicitly documented + as boundary-only and covered by tests. +4. Scoped quality gates for changed loader/tensor/I/O/tool files pass. + +### Phase 201: Guardrails, Docs, And Closeout Proof + +**Goal:** Lock the new ownership split with tests, source checks, docs, and closeout evidence. + +**Requirements:** VAL-01, VAL-02, VAL-03 + +**Success criteria:** +1. Tests cover supported tensor-to-I/O boundary behavior and representative deterministic failure + handling through public event interfaces. +2. Domain/source guardrails fail if concrete mmap/read/copy/staged strategy behavior lands in this + milestone, if `model/loader` regains low-level strategy logic, or if tensor residency ownership + moves outside `model/tensor`. +3. Public docs and planning artifacts truthfully describe `model/tensor` as the residency owner, + `emel/io` as the loading strategy boundary owner, and concrete strategy implementations as + follow-on work. +4. `scripts/check_domain_boundaries.sh` and the changed-file scoped quality gate pass before + milestone closeout. + +## Requirement Coverage + +| Requirement | Phase | Status | +|-------------|-------|--------| +| IO-01 | Phase 197 | Complete | +| IO-02 | Phase 197 | Complete | +| IO-03 | Phase 198 | Complete | +| TBOUND-01 | Phase 198 | Complete | +| TBOUND-02 | Phase 198 | Complete | +| TBOUND-03 | Phase 199 | Complete | +| POLICY-01 | Phase 199 | Complete | +| POLICY-02 | Phase 199 | Complete | +| POLICY-03 | Phase 199 | Complete | +| LOAD-01 | Phase 200 | Complete | +| LOAD-02 | Phase 200 | Complete | +| VAL-01 | Phase 201 | Complete | +| VAL-02 | Phase 201 | Complete | +| VAL-03 | Phase 201 | Complete | + +**Coverage:** 14/14 requirements mapped; 14 complete, 0 unmapped. + +## Next Up + +Milestone implementation and validation are complete.

Doctests drive supported mmap behavior through `process_event(...)` and inspect SML states. + 2. Doctests cover representative unsupported, validation failure, and mapping failure outcomes + through public events. + 3. Guardrails fail if mmap logic leaks into `model/loader` or tensor residency ownership moves + out of `model/tensor`. + 4. Guardrails fail if staged read/copy, device-specific, cooperative async, model-family widening, + loader-owned byte access, or tool-only mmap scaffolds enter this milestone. +**Plans**: 01 — Validated 2026-05-04 (repair pass); changed-file scoped quality gate green end-to-end +with no override (`scripts/quality_gates.sh` exit 0 with +`EMEL_QUALITY_GATES_CHANGED_FILES="scripts/check_domain_boundaries.sh:tests/io/mmap/lifecycle_tests.cpp:snapshots/lint/clang_format.txt"`). +20/20 io mmap doctests / 1202 assertions pass under debug and zig release builds.

Public docs and generated architecture docs describe the mmap strategy path, ownership + boundaries, and deferred strategies truthfully. + 2. Lint snapshots, benchmark snapshots, benchmark outputs, and model artifacts are updated from + maintained commands when the implementation changes them. + 3.

Concrete validation predicates, mapping attempts, and descriptor publication remain + stubbed for Phases 205/206. +3. Treat `events::map_tensor` as the public trigger event with reference fields only. Internal + completion progresses via a `detail::map_tensor_runtime` carrier that bridges request and + response across internal phases without copying request payload into context. +4. Keep `context` empty/persistent-only (no dispatch-local fields, no `request_*`, `phase`, + `error`, `*_out` members). Optional same-RTC done/error callbacks are provided through + public callback set/clear events, not by storing dispatch-local pointers. +5. Add unexpected-event handling for every state via `sml::unexpected_event`. +6. Expose canonical alias `emel::io::mmap::sm`. Do NOT route `emel::io::sm` to mmap yet — that + becomes meaningful when tensor integration lands in Phase 207. +7.

This is needed for the + unexpected-event test path, but a future tightening could private + the runtime overload behind a friend-only seam if direct dispatch + becomes a real concern. Not a Phase 205 issue and not a rule + violation today (`detail::map_tensor_runtime` lives in the + `detail::` namespace which is the established + non-public marker repo-wide). + +2. `effect_mark_unsupported_file/offset/length/layout` collapse into + `error::unsupported_resource`. This is correct under PLAT-01 (one + "fail closed on unsupported file/resource shapes" category) but + loses per-precondition diagnostic granularity. If Phase 206 / ERR-01 + needs richer error categories for diagnostics, that work is the + right place to revisit. No action needed in Phase 205. + +3. `platform_mmap_unsupported{}(ev, ctx)` calls + `platform_mmap_supported{}(ev, ctx)` and negates. Functionally fine + and matches the established `_invalid` paired-guard convention from + io/loader. Consider also exposing a class-level `static constexpr + bool` for compile-time consumers in Phase 206; not needed for the + current `if constexpr` body in the guard itself. + +4. `events::map_tensor_done` and `events::map_tensor_error` carry a + `const event::map_tensor &request` back-pointer. This is allowed by + the optional-correlation rule in AGENTS (same-RTC handoff). When + Phase 206 wires the success path, double-check that no caller stores + either outcome event past dispatch return. + +5. Phase 204's transitional `EMEL_QUALITY_GATES_ALLOW_BENCH_REGRESSION=1` + was NOT consumed by Phase 205 (no benchmark-affecting changed files + this phase). The Phase 204 carry-forward is still owed at Phase 210 + closeout. + +## Status + +Clean.

No exceptions cross any +actor or API boundary, no heap allocation occurs during dispatch, and +tensor residency ownership remains in `model/tensor`. + +## Changes + +| File | Change | +|------|--------| +| `src/emel/io/mmap/errors.hpp` | Extended error enum (`resource_exhausted`, `file_open_failed`, `mapping_failed`, `unmap_failed`, `internal_error`). Added slot pool constants `k_max_mappings`, `k_invalid_mapping_handle`, and the `EMEL_IO_MMAP_MAX_MAPPINGS` compile-time override. Default-flipped `EMEL_IO_MMAP_PLATFORM_SUPPORTED` to `1` on `__APPLE__`/`__linux__`/`__unix__`/`_WIN32`. | +| `src/emel/io/mmap/events.hpp` | Added `std::string_view file_path` to `event::map_tensor_request`, added `event::release_mapping`, extended `events::map_tensor_done` with `handle`, added `events::release_mapping_done`/`events::release_mapping_error`. | +| `src/emel/io/mmap/context.hpp` | Defined `slot` (in_use, base, mapped_bytes, os_resource, file_offset, requested_bytes) and a fixed-capacity actor-owned `context` with `std::array slots`, `std::array free_stack`, and `free_count`. Default constructor initialises the free-stack LIFO once. | +| `src/emel/io/mmap/detail.hpp` | Defined per-dispatch carriers `map_attempt_status` and `release_attempt_status`; updated `map_tensor_runtime` to reference `map_attempt_status`; added `release_mapping_runtime`. | +| `src/emel/io/mmap/guards.hpp` | Added guards: `file_path_non_empty`/`file_path_empty`, `slot_capacity_available`/`slot_pool_exhausted`, `file_open_succeeded`/`file_open_failed`, `mapping_succeeded`/`mapping_failed`, `done_callback_present`/`done_callback_absent`, `release_handle_in_range`/`release_handle_out_of_range`, `release_slot_in_use`/`release_slot_not_in_use`, `unmap_succeeded`/`unmap_failed`, and release-side callback presence guards. | +| `src/emel/io/mmap/actions.hpp` | Added inline mark/commit/release effect types and out-of-line declarations for OS-touching `effect_reserve_top_free_slot_then_attempt_open`, `effect_attempt_mapping`, `effect_close_open_resource_and_release_slot_on_mapping_failure`, and `effect_attempt_unmap`.

Added `process_event(const event::release_mapping&)` overload. | +| `tests/io/mmap/lifecycle_tests.cpp` | Updated existing Phase 205 cases to supply `file_path` so the original error categories are still reachable. Added Phase 206 cases covering mapped-descriptor success, file_open_failed (missing path), mapping_failed (mmap rejects directory fd), resource_exhausted (slot pool drained), release happy path with LIFO slot reuse, release out-of-range handle, release double-release, release without callback, success without done callback, and a boundary-source check that platform identifiers appear only in `actions.cpp`. | +| `CMakeLists.txt` | Added `src/emel/io/mmap/actions.cpp` to libemel sources. | +| `.planning/architecture/io_mmap.md`, `.planning/architecture/mermaid/io_mmap.mmd` | Regenerated by maintained `scripts/generate_docs.sh` to reflect the new transition graph. | + +## Out of Scope + +- Tensor-to-I/O integration with `model/tensor` (Phase 207). +- Public runtime/loader/benchmark/paritychecker mmap exposure (Phase 208). +- Doctest sweep covering tensor-driven flows and richer Win32-only paths (Phase 209). +- Public docs and snapshot publication beyond regenerating maintained outputs touched by this phase (Phase 210). +- Cooperative async, staged read/copy, device strategy implementations. + +## Notes + +- `event::map_tensor_request::file_path` is a `std::string_view`.

No + new file names beyond canonical bases. `detail.hpp` stays data-only + (per-dispatch carriers, slot record types). `errors.hpp`, + `guards.hpp`, `events.hpp`, `context.hpp`, `sm.hpp` follow the existing + header-only pattern. `EMEL_IO_MMAP_PLATFORM_SUPPORTED` flips to `1` + when the host is POSIX or `_WIN32`. +- **OS-call placement:** Per main constraint 6, an action performs the + already-selected OS attempt and records its raw result into the + per-dispatch runtime carrier.

No action chooses + behaviour, no detail helper chooses behaviour, no exception crosses an + actor boundary. The constraint + "ALWAYS keep actions bounded and non-blocking during dispatch" is + applied as bounded; one-shot loader-setup syscalls (`open`/`mmap`/ + `munmap`/`close`) are accepted under the same precedent that allows + one-time initialisation work outside hot inference paths.

The fd was never opened (open returned -1), + so no os_resource leak. +- **mapping failure**: reserve → open → map fails → close the + previously-opened os_resource → release reserved slot, mark + `mapping_failed`. fd is closed; slot is freed. +- **resource exhaustion**: reserve guarded by + `slot_capacity_available` (free_count > 0). When pool is drained, + `slot_pool_exhausted` routes to error decision; no slot is + consumed; no fd is opened. ✓ +- **release happy path**: handle_in_range → slot_in_use → + attempt_unmap (which snapshots base/bytes/os_resource from the + slot) → unmap succeeds → release_slot_after_unmap (clears slot + fields, pushes onto free_stack, sets ok=true) → publish done. + After return, `slot.in_use == false` and `free_count` is + incremented by 1. The next `map_tensor` dispatch reuses the + released slot index (verified by the LIFO reuse test). +- **release out-of-range**: handle >= k_max_mappings → invalid + handle. ctx.slots[handle] is never indexed because that index + predicate is gated behind handle_in_range. ✓ +- **release double**: first release marks slot in_use=false.

No double-unmap on the OS. ✓ +- **release while slot was never committed (e.g., a fabricated + handle)**: same as double-release — slot.in_use is false → routes + to invalid_handle. ✓ +- **unmap failure**: attempt_unmap reports unmap_ok=false → + effect_mark_unmap_failed_and_release_slot still releases the slot + bookkeeping (the actor never leaks a slot) and surfaces + `error::unmap_failed`. The OS resources may have leaked at the + syscall level, but that is reported deterministically and is the + best the actor can do without retry semantics. + +Edge-case math: + +- `effect_reserve_top_free_slot_then_attempt_open` decrements + `free_count` then indexes `free_stack[free_count]`. Reachable only + after the `slot_capacity_available` guard accepted + `free_count > 0`, so the indexed slot is well-defined. ✓ +- The `layout_supported` predicate from Phase 205 still guards size + against address-space wraparound before the platform attempt. ✓ +- `effect_release_reserved_slot_on_open_failure` and + `effect_close_open_resource_and_release_slot_on_mapping_failure` + push the slot back via + `ctx.free_stack[ctx.free_count] = ev.status.reserved_slot; + ctx.free_count += 1u;`. Reachable only after a prior reservation + decremented free_count, so the push slot index + (`free_count` post-pop) is the same index the pop returned — pure + LIFO. ✓ + +## Public Event Surface Contract Review + +- `event::map_tensor_request::file_path` (`std::string_view`) MUST + be backed by null-terminated storage that remains alive for the + duration of dispatch, because `actions.cpp` calls + `file_path.data()` for `open`/`CreateFileA`. The contract is + documented in `206-CONTEXT.md`, + `206-01-SUMMARY.md`, and `206-VERIFICATION.md`. Tests exercise it + via `std::string` storage whose `c_str()` is guaranteed + null-terminated. Phase 207 (model/tensor wiring) must respect this. +- `events::map_tensor_done.handle` is an opaque `uint32_t` slot + index. Callers must treat it as opaque and pass it back via + `event::release_mapping`. Out-of-range handles return + `error::invalid_request`. +- `event::release_mapping.handle` defaults to + `k_invalid_mapping_handle` so an explicit handle is required at + construction. +- `events::map_tensor_done` carries `const event::map_tensor &request` + and `events::map_tensor_error` carries the same back-pointer for + same-RTC correlation.

This is fine for current + POSIX targets; Phase 209 may want a more deterministic + sabotage harness for Windows coverage. + +2. **fd-limit considerations for the resource_exhausted test.** + The test maps the same file 256 times to drain the slot pool, + which consumes 256 fds simultaneously before releasing them. + On hosts whose `ulimit -n` is below ~270 the test would fail + prematurely with `file_open_failed` instead of + `resource_exhausted`. macOS and Linux defaults are typically + high enough; CI runners with tight rlimits should be checked. + A future tightening could compile-override + `EMEL_IO_MMAP_MAX_MAPPINGS` to a small value for the test + binary so the test costs only a few fds. + +3. **slot fields on the rollback paths.** When a slot is released + on the open-failure or mapping-failure path, only `in_use` is + reset; `base`, `mapped_bytes`, `os_resource`, + `file_offset`, `requested_bytes` keep their stale values until + the next `effect_commit_mapping` or `effect_release_slot_*` + overwrites them. This is correct because no consumer reads stale + slot fields before the next commit, but a defensive zeroing + would make the slot record easier to inspect during debugging. + Not a Phase 206 issue. + +4. **Outcome event back-pointers.** Both + `events::map_tensor_done` and `events::map_tensor_error` (and the + release variants) carry a `const event::*&` back-pointer for + same-RTC correlation. Phase 207 wiring through `model/tensor` + must not store either outcome event past the synchronous callback + return. + +5. **Phase 204 transitional bench-regression override.** Still + carry-forward; not consumed by Phase 206 (no benchmark-affecting + changed files this phase). Phase 210 owes the cleanup. + +## Status + +Clean. Phase 207 may proceed without rework of any Phase 206 io/mmap +artifact. diff --git a/.planning/milestones/v1.24-phases/206-mapped-descriptor-errors-and-lifetime/206-VALIDATION.md b/.planning/milestones/v1.24-phases/206-mapped-descriptor-errors-and-lifetime/206-VALIDATION.md new file mode 100644 index 00000000..4075f4e9 --- /dev/null +++ b/.planning/milestones/v1.24-phases/206-mapped-descriptor-errors-and-lifetime/206-VALIDATION.md @@ -0,0 +1,96 @@ +--- +phase: 206-mapped-descriptor-errors-and-lifetime +status: validated +requirements: + - MMAP-03 + - LIFE-01 + - ERR-01 +created: 2026-05-04T17:05:00Z +last_updated: 2026-05-04T17:25:00Z +--- + +# Phase 206 Validation + +## Commands Run + +| Command | Result | +|---------|--------| +| `cmake --build build/zig --target emel_tests_bin` | succeeded | +| `build/zig/emel_tests_bin --no-breaks --source-file=*tests/io/mmap/lifecycle_tests.cpp` | 18 cases / 672 assertions / 0 failures | +| `ctest --test-dir build/zig --output-on-failure` | 15/15 passed (lint_snapshot, generate_docs included) | +| `scripts/check_domain_boundaries.sh` | exit 0 | +| `scripts/lint_snapshot.sh` | exit 0 (after `clang-format -i` on new and modified mmap sources/tests) | +| `scripts/generate_docs.sh` | regenerated `.planning/architecture/io_mmap.md` and `.planning/architecture/mermaid/io_mmap.mmd` from the maintained docsgen path | +| `EMEL_QUALITY_GATES_CHANGED_FILES="" scripts/quality_gates.sh` | exit 0 (all lanes green, no override applied) | + +## Quality Gate Detail + +Per-lane outcome (`snapshots/quality_gates/timing.txt`, total 53s): + +- `domain_boundaries`: status 0 (2s). +- `legacy_sml_surface`: status 0 (1s). +- `build_with_zig`: status 0 (19s). +- `bench_snapshot`: status 0 (0s) — skipped, no benchmark-affecting + changed files.

No mirrored status +fields, no callback-selected outcomes, no dispatch-local data in +`action::context`. + +## Changes + +| File | Change | +|------|--------| +| `src/emel/model/tensor/errors.hpp` | Added `io_mmap_unsupported`, `io_mmap_failed`, `tensor_already_resident`, `tensor_unmapped` error categories. | +| `src/emel/model/tensor/events.hpp` | Added `event::request_mapped_load`, `event::release_mapped_load`, and outcome events (`request_mapped_load_done`, `request_mapped_load_error`, `release_mapped_load_done`, `release_mapped_load_error`). Added `mmap_resident` lifecycle value. The release event carries `(tensor_id, mapping_handle)` so the actor never has to scan or store handle state. | +| `src/emel/model/tensor/context.hpp` | Added a non-owning `emel::io::mmap::sm *io_mmap = nullptr` to the existing `action::context` aggregate. No new persistent state. | +| `src/emel/model/tensor/detail.hpp` | Added per-dispatch `request_mapped_load_status` and `release_mapped_load_status` carriers plus matching `request_mapped_load_runtime` and `release_mapped_load_runtime` internal events. No helpers, no scans. | +| `src/emel/model/tensor/guards.hpp` | Added pure single-field guards for the request and release chains: io_mmap presence, request validity, file_path non-empty, byte_size > 0, tensor lifecycle vs. `resident`/`mmap_resident`, io_mmap success/failure flags, and (release-side) `mapping_handle != k_invalid_mapping_handle && lifecycle == mmap_resident`. Composite guards for the `[io_mmap_present + request_valid + tensor_unbound]` decision are explicit named structs (not `&&` expressions) and call sub-guards directly without scanning storage. | +| `src/emel/model/tensor/actions.hpp` | Added inline mark/commit effects, a single OS-touching dispatch effect per surface (`effect_attempt_request_mapped_load_dispatch`, `effect_attempt_release_mapped_load_dispatch`), publish/record effects, and file-static `mapped_load_callbacks::on_io_mmap_*` trampolines that capture io/mmap outcome into the per-dispatch tensor status. The dispatch effect performs exactly one already-selected `ctx.io_mmap->process_event(...)` call. The commit effect just sets `lifecycle` and clears/sets buffer fields. No runtime `if`/`switch`/scan inside any new effect. | +| `src/emel/model/tensor/sm.hpp` | Added `request_mapped_load` and `release_mapped_load` chains: each event has a decision-state chain (validate → dispatch → commit/error → publish-or-record-callback) with explicit guards and per-state `unexpected_event` handlers returning to `ready`. Added a `process_event(const event::request_mapped_load&)` overload, a `process_event(const event::release_mapped_load&)` overload, an `explicit sm(emel::io::mmap::sm*)` constructor (so callers can inject the io/mmap dispatcher without referencing the `action::` namespace), and a private `make_context_with_io_mmap` helper. `using base_type::base_type;` inherits the existing default + context constructors. | +| `tests/model/tensor/lifecycle_tests.cpp` | Added 8 new doctest cases covering request happy path, request without io_mmap, request file_open_failed surfacing, request rejected as already resident, release happy path with eviction + capture_tensor_state verification, release rejected with no prior mapping, release rejected when io_mmap absent, request rejected with empty file_path. Tests use the public `sm(io_mmap*)` constructor; no `emel::model::tensor::action::`/`detail::`/`guard::` reach-through. | +| `.planning/architecture/model_tensor.md`, `.planning/architecture/mermaid/model_tensor.mmd` | Regenerated by maintained `scripts/generate_docs.sh` to reflect the new transition graph. | + +No `CMakeLists.txt` change.

The release event + carries `(tensor_id, mapping_handle)`. The caller obtained the + handle from `events::request_mapped_load_done.mapping_handle` and + passes it back when releasing. Tensor only checks + `lifecycle == mmap_resident` plus a non-invalid handle on the public + event before dispatching. +- **No runtime branching in actions.** Every behaviour decision is in + a guard. Effects only mark per-dispatch status, perform an + already-selected OS call (the cross-actor `process_event(...)`), + publish/record outcomes, or update tensor lifecycle/buffer fields. +- **No detail-helper output drives routing.** `detail.hpp` contains + data carriers only. Guards inline their own per-tensor field + reads. Actions use `ev.request.mapping_handle` directly. +- **Context discipline.** `action::context` holds persistent + actor-owned state (`tensor_storage` from prior phases) plus the + injected `io_mmap` dispatcher pointer. No request, output, status, + phase, or step fields in context. +- **Tensor lifecycle expansion.** The existing enum gained a + `mmap_resident` value to distinguish io/mmap-loaded tensors from + caller-buffer-bound (`resident`) ones. The + `request_mapped_load_tensor_already_resident` guard rejects either + state so a tensor can't be double-loaded. +- **Phase 204 transitional bench-regression override.** NOT consumed. + Phase 207 ran without `EMEL_QUALITY_GATES_ALLOW_BENCH_REGRESSION=1`; + the `bench_snapshot` lane reported status 0.

reject legacy evict of mmap-resident tensors Closes PR #83 P1 review threads: - PRRT_kwDORRHzJs5_hhbx (src/emel/io/mmap/actions.hpp:209-225): on unmap failure the OS mapping/file descriptor may still be live, so effect_mark_unmap_failed_and_release_slot must keep the slot owned (in_use/base/mapped_bytes/os_resource intact) and not push the handle back onto free_stack. The caller can then retry release and a later map_tensor cannot reuse the slot while the prior mapping leaks. - PRRT_kwDORRHzJs5_hhby (src/emel/model/tensor/guards.hpp): the legacy evict_tensor path nulled tensor pointers without releasing the mmap mapping, leaking the slot and OS mapping. evict_tensor_request_valid now rejects mmap_resident lifecycle so the legacy evict routes to errored. Mapped tensors must be released through release_mapped_load. Failing unit coverage added first per AGENTS.md: - tests/io/mmap/lifecycle_tests.cpp 'io mmap unmap failure keeps mapping slot owned for retry' drives effect_mark_unmap_failed_and_release_slot against a constructed live-slot context and asserts in_use stays true, base/bytes/os_resource preserved, and the handle does not appear in free_stack. - tests/model/tensor/lifecycle_tests.cpp 'model_tensor_evict_tensor_rejects_mmap_resident_tensors' brings a tensor to mmap_resident via request_mapped_load, dispatches legacy evict_tensor, asserts CHECK_FALSE on the dispatch and invalid_request error_out, confirms lifecycle/buffer/handle survive, and proves the proper release_mapped_load path still works after the rejected evict. snapshots/lint/clang_format.txt baseline refreshed via maintained scripts/lint_snapshot.sh --update to register the now-clang-formatted tests/io/mmap/lifecycle_tests.cpp (single-line addition). --- snapshots/lint/clang_format.txt | 1 + src/emel/io/mmap/actions.hpp | 18 +++---- src/emel/model/tensor/guards.hpp | 15 ++++-- tests/io/mmap/lifecycle_tests.cpp | 63 ++++++++++++++++++++++++ tests/model/tensor/lifecycle_tests.cpp | 68 ++++++++++++++++++++++++++ 5 files changed, 151 insertions(+), 14 deletions(-) diff --git a/snapshots/lint/clang_format.txt b/snapshots/lint/clang_format.txt index be9b3a3b..ce8029d7 100644 --- a/snapshots/lint/clang_format.txt +++ b/snapshots/lint/clang_format.txt @@ -574,6 +574,7 @@ tests/graph/processor/processor_tests.cpp tests/graph/tensor/lifecycle_tests.cpp tests/graph/wrapper_visibility_tests.cpp tests/io/loader/lifecycle_tests.cpp +tests/io/mmap/lifecycle_tests.cpp tests/kernel/aarch64_tests.cpp tests/kernel/lifecycle_tests.cpp tests/kernel/test_helpers.hpp diff --git a/src/emel/io/mmap/actions.hpp b/src/emel/io/mmap/actions.hpp index 25a11404..933570e0 100644 --- a/src/emel/io/mmap/actions.hpp +++ b/src/emel/io/mmap/actions.hpp @@ -207,18 +207,14 @@ struct effect_release_slot_after_unmap { }; struct effect_mark_unmap_failed_and_release_slot { + // When platform_unmap fails, the OS mapping (and its file handle) may still + // be live.
