From 7d53cef0cf7fa0f6c1e44614bbf1a3b739cbcee7 Mon Sep 17 00:00:00 2001 From: Oleksandr Bezdieniezhnykh Date: Wed, 20 May 2026 17:30:26 +0300 Subject: [PATCH] [AZ-701] HTTP replay API service (FastAPI + magic-byte upload validation) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit New replay_api component: FastAPI service wrapping the offline gps-denied-replay pipeline. POST tlog+video (multipart) → either sync 200 with result/map/report URLs, or async 202 + job id with /jobs/{id} polling. Magic-byte validation, bearer auth, in-memory JobRegistry with concurrency + queue caps (429 on overflow). Helper accuracy_report.py promoted from tests/ to src/ because the API needs the Markdown report writer at runtime; all AZ-699 imports re-pointed. OpenAPI spec exported to docs. 18/18 unit tests pass (AC-1 sync, AC-2 async, AC-3 state machine, AC-5 auth, AC-6 health, AC-8 concurrency, AC-9 magic-byte). Full unit suite: 2251 pass, 86 skip, 1 pre-existing C12 cold-start flake (unchanged). mypy --strict clean on the new surface.

Earlier draft used a separate registry-assigned id and tried to "release-then-resubmit"; that path deleted the dir holding the uploads. Fixed by adding the optional `job_id` parameter. +- **`from __future__ import annotations` deliberately dropped in `app.py`**: FastAPI 0.119 + Pydantic v2 resolve route-parameter annotations at decoration time. Forward-ref strings break `Annotated[UploadFile, File()]`. The rest of the `replay_api` package keeps the future-annotations import. The reason is captured in the `app.py` module docstring. +- **Pydantic v2 `Annotated` syntax**: every route parameter uses `Annotated[T, File()/Form()/Header()]` rather than the legacy `T = File(...)` form. Older form raised `PydanticUserError: 'UploadFile' is not fully defined`. +- **Magic-byte validation is mandatory, not advisory**: matches AC-9 wording ("Wrong magic bytes → 400"). Anything that's not MAVLink v1/v2 (`\xfe` / `\xfd` first byte) is rejected as tlog; anything without `ftyp` in bytes 4-12 is rejected as video. No `application/x-mavlink` content-type sniffing. +- **State is in-memory only**: matches "no persistent state across restarts" invariant in the contract. Operators wanting durability can layer it externally (or move to AZ-702 follow-on). Documented in the contract. + +### Known Limitations + +- `SubprocessReplayRunner` returns `result.stdout`/`stderr` only when the subprocess fails; success path discards them. Operators wanting a per-job audit log will need a follow-on. +- No request body streaming — `python-multipart` buffers each part. The 2 GB hard limit guards memory. +- No rate limiting beyond the concurrency/queue caps. A reverse proxy is the right place for that. +- E2E test against the real Derkachi flight artefacts is intentionally NOT in scope here (per the testing-environment rule: e2e runs on Jetson only and AZ-699's `test_derkachi_real_tlog.py` already exercises the underlying pipeline). diff --git a/_docs/03_implementation/batch_102_cycle2_report.md b/_docs/03_implementation/batch_102_cycle2_report.md new file mode 100644 index 0000000..c2f4238 --- /dev/null +++ b/_docs/03_implementation/batch_102_cycle2_report.md @@ -0,0 +1,146 @@ +# Batch 102 — Cycle 2 — AZ-701 + +**Date**: 2026-05-20 +**Tasks**: AZ-701 (HTTP replay API service). +**Story points**: 5. +**Jira status**: AZ-701 → `In Testing`. + +## What shipped + +A new operator-side `replay_api` component — a FastAPI service that +wraps the offline `gps-denied-replay` pipeline behind HTTP.
