From e4d73375934ba7c11de21ae719ad957cdf0be248 Mon Sep 17 00:00:00 2001 From: Mohammed Sufiyan Saqib <34838688+sufiyansaqib@users.noreply.github.com> Date: Tue, 12 May 2026 05:03:22 +0530 Subject: [PATCH 01/18] [Feature - NOKIA] Controller multiprocessing, time chunking, cache safety, tracking improvements (#1317) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Nokia enhancements to Intel SceneScape 2025.2 — controller and multiprocessing changes only. No Triton/GPU dependencies. Split from #1306 as requested — Triton changes will follow separately. For a detailed technical walkthrough of all changes with code references, see [docs/controller-enhancements-technical-reference.md] Changes SceneController multiprocessing (scene_controller.py): ProcessPoolExecutor per scene (spawn context), overwrite buffer, semaphore admission control (default 20), async MQTT publish on dedicated thread, automatic crash recovery on BrokenProcessPool, publish watchdog every 30s Scene-aware time chunking (time_chunking.py): Replaced flat TimeChunkBuffer with SceneAwareCategoryBuffer — groups cameras by scene, hybrid dispatch (event-driven when all cameras arrive + 200ms timer fallback), fixed-rate scheduling via time.monotonic() to prevent drift Thread-safe CacheManager (cache_manager.py): _fast dict-only lookup methods safe for MQTT callback thread; HTTP refresh moved to background thread (60s interval); lock held only during in-memory updates, never during HTTP I/O O(1) object association (ilabs_tracking.py): Pre-built hash maps replace O(n) linear scans; UUID stability fix includes unreliable + suspended tracks in pruning C++ tracker bindings (robot_vision): Expose getSuspendedTracks() and getUnreliableTracks() from C++ tracker for UUID stability fix Schema extensions (metadata.schema.json): Add reid, facemask, color, age, hat, gender, subtype fields Tracker retuning (tracker-config.json): Tuned for 10 FPS operation REST client fixes (rest_client.py): Fix token not assigned, url=None crash, rootcert ignored for TLS verification Dockerfile/Makefile: Default to public Ubuntu image; Nokia mirror overridable via RUNTIME_OS_IMAGE build arg/env var UI (sscape.js, style.css): SVG coordinate fix, scale controls (Fit/Native/75/50/33%), Show IDs toggle Signed-off-by: Mohammed Sufiyan Saqib mohammed.sufiyan_saqib@nokia.com --- controller/Dockerfile | 8 +- controller/Makefile | 11 +- controller/config/tracker-config.json | 10 +- controller/requirements-runtime.txt | 7 +- controller/src/controller-cmd | 76 +- controller/src/controller/cache_manager.py | 325 +++-- .../src/controller/child_scene_controller.py | 7 +- controller/src/controller/controller_mode.py | 49 + .../src/controller/detections_builder.py | 22 +- controller/src/controller/ilabs_tracking.py | 190 ++- controller/src/controller/moving_object.py | 82 +- .../src/controller/observability/metrics.py | 6 +- controller/src/controller/reid.py | 6 +- controller/src/controller/scene.py | 141 +- controller/src/controller/scene_controller.py | 1198 +++++++++++++++-- .../src/controller/test_time_chunking.py | 371 +++++ controller/src/controller/time_chunking.py | 631 +++++++-- controller/src/controller/tracking.py | 77 +- controller/src/controller/uuid_manager.py | 20 +- controller/src/controller/vdms_adapter.py | 11 +- .../gated_hungarian_bigraph_matcher.hpp | 39 +- .../rv/tracking/MultipleObjectTracker.hpp | 14 +- .../include/rv/tracking/TrackManager.hpp | 4 +- .../src/robot_vision/extensions/tracking.cpp | 12 +- controller/src/robot_vision/requirements.txt | 4 +- controller/src/robot_vision/setup.py | 15 +- .../src/rv/tracking/TrackManager.cpp | 4 +- controller/src/schema/metadata.schema.json | 58 +- ...roller-enhancements-technical-reference.md | 1175 ++++++++++++++++ .../templates/scene-controller/configmap.yaml | 11 + .../scene-controller/deployment.yaml | 22 + manager/src/static/css/style.css | 50 +- manager/src/static/js/marks.js | 30 + manager/src/static/js/sscape.js | 95 +- manager/src/templates/sscape/sceneDetail.html | 28 +- scene_common/src/scene_common/options.py | 3 + scene_common/src/scene_common/rest_client.py | 40 +- 37 files changed, 4366 insertions(+), 486 deletions(-) create mode 100644 controller/src/controller/controller_mode.py create mode 100644 controller/src/controller/test_time_chunking.py create mode 100644 docs/controller-enhancements-technical-reference.md diff --git a/controller/Dockerfile b/controller/Dockerfile index 0dbd058f4..7c403bb96 100644 --- a/controller/Dockerfile +++ b/controller/Dockerfile @@ -1,10 +1,12 @@ # SPDX-FileCopyrightText: (C) 2021 - 2025 Intel Corporation # SPDX-License-Identifier: Apache-2.0 +# Modifications: +# Nokia VPOD (Emerging Products, BLR), 2026 -ARG RUNTIME_OS_IMAGE=ubuntu:24.04@sha256:a08e551cb33850e4740772b38217fc1796a66da2506d312abe51acda354ff061 +ARG RUNTIME_OS_IMAGE=ubuntu:noble-20260113@sha256:cd1dba651b3080c3686ecf4e3c4220f026b521fb76978881737d24f200828b2b # -------------- Common Base Stage (ported to Ubuntu 24.04) -------------- -FROM ubuntu:24.04@sha256:a08e551cb33850e4740772b38217fc1796a66da2506d312abe51acda354ff061 AS scenescape-common-base-24-04 +FROM ${RUNTIME_OS_IMAGE} AS scenescape-common-base-24-04 # We use root for runtime init.

OVERVIEW: Performance enhancement that reduces tracking load by processing only the most recent -detection frame from each camera+category combination within time windows. Instead of -processing every incoming message immediately, buffers them and dispatches only the -latest data every 50ms (default interval, configurable). - -IMPLEMENTATION: -- TimeChunkedIntelLabsTracking: Inherits from IntelLabsTracking, overrides trackObjects() -- TimeChunkProcessor: Timer thread that manages buffering and periodic dispatch -- TimeChunkBuffer: Thread-safe storage that keeps only latest frame per camera+category - -FEATURES: -- Object Batching: Currently disabled (ENABLE_OBJECT_BATCHING=False). When enabled, - batches objects from all cameras per category into a single tracker call for improved performance +detection frame from each camera within fixed time windows. Uses a simple overwrite +hashmap per category that guarantees: +1. Always processes the freshest frame per camera +2. All active cameras are batched together at each interval +3. Predictable timing with configurable interval (default 200ms) +4. Early dispatch when all cameras for a scene arrive (event-driven fast path) + +DESIGN (Hybrid Sample-and-Hold with Event-Driven Dispatch): +- MQTT callbacks continuously overwrite the latest frame per camera in a dict +- When all cameras for a scene arrive (count derived from CacheManager), dispatch immediately +- Timer thread dispatches remaining partial scenes at fixed intervals (scheduled wake) +- Fixed-rate scheduling via time.monotonic() prevents timer drift under load +- If tracker is slow, we simply skip that interval (fresher data will come) + +CAMERA COUNT RESOLUTION: +The expected camera count per scene is derived dynamically at runtime from CacheManager +(len(scene.cameras)), not from a static config value. This auto-adapts when cameras are +added or removed without requiring config changes. If the CacheManager lookup fails +(scene not yet cached), early dispatch is skipped and the timer handles it. USAGE: TimeChunkedIntelLabsTracking is configurable via tracker-config.json: - Set "time_chunking_enabled": true to enable time-chunked tracking -- Set "time_chunking_interval_milliseconds": 50 to set processing interval (optional, defaults to 50ms if not present) -The Scene class will automatically select TimeChunkedIntelLabsTracking when enabled, otherwise uses standard IntelLabsTracking. +- Set "time_chunking_interval_milliseconds": 200 for 200ms batching interval Example tracker-config.json: { "max_unreliable_frames": 10, - "non_measurement_frames_dynamic": 8, - "non_measurement_frames_static": 16, - "baseline_frame_rate": 30, + "non_measurement_frames_dynamic": 20, + "non_measurement_frames_static": 30, + "baseline_frame_rate": 10, "time_chunking_enabled": true, - "time_chunking_interval_milliseconds": 50 + "time_chunking_interval_milliseconds": 200 } """ import threading import time -from typing import Any, List +from collections import defaultdict +from typing import Any, Callable, Dict, List, Optional from scene_common import log from controller.ilabs_tracking import IntelLabsTracking -from controller.tracking import BATCHED_MODE, STREAMING_MODE, DEFAULT_SUSPENDED_TRACK_TIMEOUT_SECS -from controller.observability import metrics - -DEFAULT_CHUNKING_INTERVAL_MS = 50 # Default interval in milliseconds - -# TODO: object batching is not working yet, needs fixing tracker matching logic first -ENABLE_OBJECT_BATCHING = True # Hardcoded to False - batch objects from all cameras per category for single tracker call - -class TimeChunkBuffer: - """Buffer organized by category, then by camera for efficient grouping""" - - def __init__(self): - self._data = {} # Structure: {category: {camera_id: (objects, when, already_tracked)}} +from controller.tracking import BATCHED_MODE + +DEFAULT_CHUNKING_INTERVAL_MS = 200 # Default interval - 5 batches/sec +DEFAULT_PARTIAL_SCENE_TIMEOUT_SEC = 0.2 # Timeout for incomplete scenes + +# Global cache_manager instance for scene_id lookup (set by scene_controller at startup) +_cache_manager = None + +def set_cache_manager(cache_manager): + """Set the global cache_manager instance for scene_id derivation.""" + global _cache_manager + _cache_manager = cache_manager + +def _get_scene_camera_count(scene_id): + """Look up actual camera count for a scene from CacheManager. + + Returns the number of cameras registered for this scene, or None if the + scene is not (yet) in the cache.

Bug Fixes + +### 2.1 Multi-Category Tripwire/Region Event Loss + +`scene.py:180` + +When a camera detects multiple object categories in a single frame (e.g., both +`person` and `vehicle`), only the last category's tripwire/region events were +published. Events from all earlier categories were silently lost. + +**Root cause:** `self.events = {}` was reset inside `_updateEvents()`, which was +called once per detection type inside the `processCameraData()` loop. Each +iteration wiped events accumulated by previous categories. + +**Before:** +```python +def processCameraData(self, jdata, when=None, ignoreTimeFlag=False): + for detection_type, detections in jdata['objects'].items(): + objects = self._createSceneObjects(detection_type, detections) + self._finishProcessing(detection_type, when, objects) + return True + +def _updateEvents(self, detectionType, now): + self.events = {} # <-- Resets on every category + # ... accumulate events ... +``` + +**After (`scene.py:180-181`):** +```python +def processCameraData(self, jdata, when=None, ignoreTimeFlag=False): + self.events = {} # Reset ONCE before loop + for detection_type, detections in jdata['objects'].items(): + objects = self._createSceneObjects(detection_type, detections) + self._finishProcessing(detection_type, when, objects, camera_id=camera_id) + return True + +def _updateEvents(self, detectionType, now): + # NO self.events = {} here -- events accumulate across categories +``` + +### 2.2 Mutable Default Argument + +`scene.py:287-289` + +**Before:** +```python +def _finishProcessing(self, detectionType, when, objects, already_tracked_objects=[]): + # ^^^^^^^^^^^^^^^^^^^^^^^^^ + # Shared mutable list across all calls — Python gotcha +``` + +**After:** +```python +def _finishProcessing(self, detectionType, when, objects, already_tracked_objects=None, + camera_id=None): + if already_tracked_objects is None: + already_tracked_objects = [] +``` + +Python mutable defaults are created once at function definition time. Appending +to the list in one call would affect subsequent calls. + +### 2.3 Wrong Exception Type + +`tracking.py:136, 140` + +```python +# Before: +raise NotImplemented # Returns the NotImplemented singleton (used for binary ops) + +# After: +raise NotImplementedError # Correct: raises an actual exception +``` + +### 2.4 No-Op classDict.update + +`moving_object.py:304` + +```python +# Before: +classDict.update('') # No-op: str has no key-value pairs for dict.update() + +# After: Removed. Code now guards with "if methods:" before calling classDict.update(methods) +``` + +--- + +## 3. Multi-Process Worker Architecture + +`scene_controller.py` + +### 3.1 ProcessPoolExecutor Per Scene + +`scene_controller.py:280-308` + +Each scene gets a dedicated `ProcessPoolExecutor(max_workers=1)`, created on +demand when the first message for that scene arrives. Worker processes are +isolated: each has its own `SceneController` instance with independent +CacheManager, Scene, and Tracker state. + +```python +# scene_controller.py:300-305 +executor = ProcessPoolExecutor( + max_workers=1, + mp_context=multiprocessing.get_context('spawn'), + initializer=_init_worker_process, + initargs=(self._worker_config,)) +``` + +**Why `spawn` not `fork`:** Fork copies the parent process including all its +threads. In Python, forking a multithreaded process is unsafe — mutexes held by +threads in the parent are copied in a locked state to the child, where no thread +will ever unlock them. This causes deadlocks. Spawn starts a fresh Python +interpreter, initializes cleanly, then calls the initializer function. + +Module-level picklable functions enable ProcessPoolExecutor: + +```python +# scene_controller.py:77-85 +_worker_controller = None + +def _init_worker_process(config): + global _worker_controller + _worker_controller = SceneController(**config, _is_worker=True) + +def _worker_handle_message(topic_str, payload, t_callback_enter): + return _worker_controller._processMovingObjectMessage( + topic_str, payload, t_callback_enter) +``` + +Worker config is built by `_build_worker_config()` (`scene_controller.py:261-278`), +which returns a picklable dict of constructor args. + +### 3.2 Overwrite-Based Freshness Buffer + +`scene_controller.py:213` + +At most one pending frame per camera exists. New frames atomically overwrite +stale ones. + +```python +# scene_controller.py:213 +self._latest_frame = {} # {camera_id: (topic_str, payload, t_callback_enter)} +``` + +``` +Camera A sends Frame 1 --> _latest_frame["camA"] = Frame 1 +Camera A sends Frame 2 --> _latest_frame["camA"] = Frame 2 (Frame 1 overwritten) +Worker picks up Frame 2 --> processes latest data +``` + +This prevents unbounded queue growth: no matter how fast frames arrive, at most +1 is buffered per camera. + +### 3.3 Semaphore Admission Control + +`scene_controller.py:206-207` + +```python +MAX_INFLIGHT_MESSAGES = _validated_env_int('CONTROLLER_MAX_INFLIGHT', 20, minimum=1) +self._inflight_semaphore = threading.Semaphore(MAX_INFLIGHT_MESSAGES) +``` + +Non-blocking acquire at `scene_controller.py:1032`: if 20 messages are already +in-flight, new messages are dropped. The overwrite buffer ensures the latest +frame is still available when a slot opens. + +### 3.4 Worker Crash Recovery + +`scene_controller.py:1070, 348-366` + +```python +# scene_controller.py:1070 +except BrokenProcessPool as e: + log.error(f"[BROKEN_POOL] scene={scene_uid}, recreating executor: {e}") + self._recreate_scene_executor(scene_uid) + self._inflight_semaphore.release() +``` + +A single worker crash (e.g., segfault in the C++ tracker) does not kill the +controller. The executor is automatically recreated at `_recreate_scene_executor()` +(`scene_controller.py:348-366`) and processing resumes on the next frame. + +### 3.5 Sole-Owner Re-Submission Pattern + +`scene_controller.py:964-971, 1038-1098` + +Both the MQTT callback thread and the worker done-callback could submit work for +the same camera simultaneously, causing duplicate submissions and semaphore +accounting errors. + +**Fix:** The MQTT thread NEVER removes or replaces entries in `_pending_work`. +Only the done callback does. + +```python +# scene_controller.py:964-971 — MQTT thread: returns if ANY entry exists +with self._pending_work_lock: + if camera_id in self._pending_work: + return # Let _handle_work_complete handle re-submission + +# scene_controller.py:1038-1098 — Done callback: sole owner of re-submission +def _handle_work_complete(self, camera_id, scene_uid): + self._inflight_semaphore.release() + frame = self._get_latest_frame(camera_id) + if frame is not None: + # Re-submit with store-before-callback pattern + else: + # Clean up entry so MQTT thread can submit next time + with self._pending_work_lock: + self._pending_work.pop(camera_id, None) +``` + +### 3.6 Store-Before-Callback Race Fix + +`scene_controller.py:1002-1011` + +If `executor.submit()` returns a future that completes before +`add_done_callback()` is called, CPython fires the callback synchronously. If +the future isn't stored in `_pending_work` yet, the callback finds no entry. + +```python +# WRONG ORDER: +future = executor.submit(...) +future.add_done_callback(...) # Callback fires NOW before store +_pending_work[cam] = future # Too late — entry orphaned + +# CORRECT ORDER (current implementation): +future = executor.submit(...) +_pending_work[cam] = future # Store FIRST +future.add_done_callback(...) # Safe — callback finds the entry +``` + +### 3.7 Graceful Shutdown + +`scene_controller.py:437-476` + +```python +def shutdown(self): + # 1. Signal monitoring threads to stop + # 2. Stop cache refresh thread + # 3. Drain async publish queue (5s timeout) + # 4. Shutdown all scene executors (wait for in-flight work) + # 5. Shutdown tracker threads (uuid_manager cleanup) +``` + +Ensures clean exit: no orphaned processes, no lost messages in the publish queue. +Executors are collected under lock, then shut down outside the lock to avoid +blocking callbacks (`scene_controller.py:462-468`). + +--- + +## 4. Async MQTT Publishing + +`scene_controller.py:189-196, 561-567` + +### 4.1 Dedicated Publish Thread + +```python +# scene_controller.py:189-196 +self._publish_queue = queue.Queue(maxsize=ASYNC_PUBLISH_QUEUE_SIZE) # default 1000 +self._publish_shutdown = threading.Event() +self._publish_thread = threading.Thread( + target=self._publish_thread_loop, name="AsyncPublish", daemon=True) +self._publish_thread.start() +``` + +**Why:** Synchronous MQTT publish on the worker thread adds latency to the +tracking critical path. The paho MQTT client is NOT thread-safe — concurrent +publish from multiple workers corrupts the SSL connection. + +All `publish()` calls route through `_async_publish()` (`scene_controller.py:561`), +which places messages on the bounded queue. The dedicated thread drains the +queue under `_publish_lock` (`scene_controller.py:169`). + +### 4.2 Publish Watchdog + +`scene_controller.py:368-401` + +```python +def _publish_watchdog_loop(self): + """Monitor publish thread health every 30 seconds. Auto-restart if dead.""" +``` + +If the publish thread dies silently (e.g., unhandled exception), the watchdog +detects it within 30 seconds and restarts it.

Bug Fixes - -### 2.1 Multi-Category Tripwire/Region Event Loss - -`scene.py:180` - -When a camera detects multiple object categories in a single frame (e.g., both -`person` and `vehicle`), only the last category's tripwire/region events were -published. Events from all earlier categories were silently lost. - -**Root cause:** `self.events = {}` was reset inside `_updateEvents()`, which was -called once per detection type inside the `processCameraData()` loop. Each -iteration wiped events accumulated by previous categories. - -**Before:** -```python -def processCameraData(self, jdata, when=None, ignoreTimeFlag=False): - for detection_type, detections in jdata['objects'].items(): - objects = self._createSceneObjects(detection_type, detections) - self._finishProcessing(detection_type, when, objects) - return True - -def _updateEvents(self, detectionType, now): - self.events = {} # <-- Resets on every category - # ... accumulate events ... -``` - -**After (`scene.py:180-181`):** -```python -def processCameraData(self, jdata, when=None, ignoreTimeFlag=False): - self.events = {} # Reset ONCE before loop - for detection_type, detections in jdata['objects'].items(): - objects = self._createSceneObjects(detection_type, detections) - self._finishProcessing(detection_type, when, objects, camera_id=camera_id) - return True - -def _updateEvents(self, detectionType, now): - # NO self.events = {} here -- events accumulate across categories -``` - -### 2.2 Mutable Default Argument - -`scene.py:287-289` - -**Before:** -```python -def _finishProcessing(self, detectionType, when, objects, already_tracked_objects=[]): - # ^^^^^^^^^^^^^^^^^^^^^^^^^ - # Shared mutable list across all calls — Python gotcha -``` - -**After:** -```python -def _finishProcessing(self, detectionType, when, objects, already_tracked_objects=None, - camera_id=None): - if already_tracked_objects is None: - already_tracked_objects = [] -``` - -Python mutable defaults are created once at function definition time. Appending -to the list in one call would affect subsequent calls. - -### 2.3 Wrong Exception Type - -`tracking.py:136, 140` - -```python -# Before: -raise NotImplemented # Returns the NotImplemented singleton (used for binary ops) - -# After: -raise NotImplementedError # Correct: raises an actual exception -``` - -### 2.4 No-Op classDict.update - -`moving_object.py:304` - -```python -# Before: -classDict.update('') # No-op: str has no key-value pairs for dict.update() - -# After: Removed. Code now guards with "if methods:" before calling classDict.update(methods) -``` - ---- - -## 3. Multi-Process Worker Architecture - -`scene_controller.py` - -### 3.1 ProcessPoolExecutor Per Scene - -`scene_controller.py:280-308` - -Each scene gets a dedicated `ProcessPoolExecutor(max_workers=1)`, created on -demand when the first message for that scene arrives. Worker processes are -isolated: each has its own `SceneController` instance with independent -CacheManager, Scene, and Tracker state. - -```python -# scene_controller.py:300-305 -executor = ProcessPoolExecutor( - max_workers=1, - mp_context=multiprocessing.get_context('spawn'), - initializer=_init_worker_process, - initargs=(self._worker_config,)) -``` - -**Why `spawn` not `fork`:** Fork copies the parent process including all its -threads. In Python, forking a multithreaded process is unsafe — mutexes held by -threads in the parent are copied in a locked state to the child, where no thread -will ever unlock them. This causes deadlocks. Spawn starts a fresh Python -interpreter, initializes cleanly, then calls the initializer function. - -Module-level picklable functions enable ProcessPoolExecutor: - -```python -# scene_controller.py:77-85 -_worker_controller = None - -def _init_worker_process(config): - global _worker_controller - _worker_controller = SceneController(**config, _is_worker=True) - -def _worker_handle_message(topic_str, payload, t_callback_enter): - return _worker_controller._processMovingObjectMessage( - topic_str, payload, t_callback_enter) -``` - -Worker config is built by `_build_worker_config()` (`scene_controller.py:261-278`), -which returns a picklable dict of constructor args. - -### 3.2 Overwrite-Based Freshness Buffer - -`scene_controller.py:213` - -At most one pending frame per camera exists. New frames atomically overwrite -stale ones. - -```python -# scene_controller.py:213 -self._latest_frame = {} # {camera_id: (topic_str, payload, t_callback_enter)} -``` - -``` -Camera A sends Frame 1 --> _latest_frame["camA"] = Frame 1 -Camera A sends Frame 2 --> _latest_frame["camA"] = Frame 2 (Frame 1 overwritten) -Worker picks up Frame 2 --> processes latest data -``` - -This prevents unbounded queue growth: no matter how fast frames arrive, at most -1 is buffered per camera. - -### 3.3 Semaphore Admission Control - -`scene_controller.py:206-207` - -```python -MAX_INFLIGHT_MESSAGES = _validated_env_int('CONTROLLER_MAX_INFLIGHT', 20, minimum=1) -self._inflight_semaphore = threading.Semaphore(MAX_INFLIGHT_MESSAGES) -``` - -Non-blocking acquire at `scene_controller.py:1032`: if 20 messages are already -in-flight, new messages are dropped. The overwrite buffer ensures the latest -frame is still available when a slot opens. - -### 3.4 Worker Crash Recovery - -`scene_controller.py:1070, 348-366` - -```python -# scene_controller.py:1070 -except BrokenProcessPool as e: - log.error(f"[BROKEN_POOL] scene={scene_uid}, recreating executor: {e}") - self._recreate_scene_executor(scene_uid) - self._inflight_semaphore.release() -``` - -A single worker crash (e.g., segfault in the C++ tracker) does not kill the -controller. The executor is automatically recreated at `_recreate_scene_executor()` -(`scene_controller.py:348-366`) and processing resumes on the next frame. - -### 3.5 Sole-Owner Re-Submission Pattern - -`scene_controller.py:964-971, 1038-1098` - -Both the MQTT callback thread and the worker done-callback could submit work for -the same camera simultaneously, causing duplicate submissions and semaphore -accounting errors. - -**Fix:** The MQTT thread NEVER removes or replaces entries in `_pending_work`. -Only the done callback does. - -```python -# scene_controller.py:964-971 — MQTT thread: returns if ANY entry exists -with self._pending_work_lock: - if camera_id in self._pending_work: - return # Let _handle_work_complete handle re-submission - -# scene_controller.py:1038-1098 — Done callback: sole owner of re-submission -def _handle_work_complete(self, camera_id, scene_uid): - self._inflight_semaphore.release() - frame = self._get_latest_frame(camera_id) - if frame is not None: - # Re-submit with store-before-callback pattern - else: - # Clean up entry so MQTT thread can submit next time - with self._pending_work_lock: - self._pending_work.pop(camera_id, None) -``` - -### 3.6 Store-Before-Callback Race Fix - -`scene_controller.py:1002-1011` - -If `executor.submit()` returns a future that completes before -`add_done_callback()` is called, CPython fires the callback synchronously. If -the future isn't stored in `_pending_work` yet, the callback finds no entry. - -```python -# WRONG ORDER: -future = executor.submit(...) -future.add_done_callback(...) # Callback fires NOW before store -_pending_work[cam] = future # Too late — entry orphaned - -# CORRECT ORDER (current implementation): -future = executor.submit(...) -_pending_work[cam] = future # Store FIRST -future.add_done_callback(...) # Safe — callback finds the entry -``` - -### 3.7 Graceful Shutdown - -`scene_controller.py:437-476` - -```python -def shutdown(self): - # 1. Signal monitoring threads to stop - # 2. Stop cache refresh thread - # 3. Drain async publish queue (5s timeout) - # 4. Shutdown all scene executors (wait for in-flight work) - # 5. Shutdown tracker threads (uuid_manager cleanup) -``` - -Ensures clean exit: no orphaned processes, no lost messages in the publish queue. -Executors are collected under lock, then shut down outside the lock to avoid -blocking callbacks (`scene_controller.py:462-468`). - ---- - -## 4. Async MQTT Publishing - -`scene_controller.py:189-196, 561-567` - -### 4.1 Dedicated Publish Thread - -```python -# scene_controller.py:189-196 -self._publish_queue = queue.Queue(maxsize=ASYNC_PUBLISH_QUEUE_SIZE) # default 1000 -self._publish_shutdown = threading.Event() -self._publish_thread = threading.Thread( - target=self._publish_thread_loop, name="AsyncPublish", daemon=True) -self._publish_thread.start() -``` - -**Why:** Synchronous MQTT publish on the worker thread adds latency to the -tracking critical path. The paho MQTT client is NOT thread-safe — concurrent -publish from multiple workers corrupts the SSL connection. - -All `publish()` calls route through `_async_publish()` (`scene_controller.py:561`), -which places messages on the bounded queue. The dedicated thread drains the -queue under `_publish_lock` (`scene_controller.py:169`). - -### 4.2 Publish Watchdog - -`scene_controller.py:368-401` - -```python -def _publish_watchdog_loop(self): - """Monitor publish thread health every 30 seconds. Auto-restart if dead.""" -``` - -If the publish thread dies silently (e.g., unhandled exception), the watchdog -detects it within 30 seconds and restarts it.

Thread-Safe Cache Manager - -`cache_manager.py` - -### 5.1 The Problem - -The baseline `CacheManager` made HTTP calls during cache lookups. When called -from the MQTT callback thread, these HTTP calls blocked paho's network loop: - -``` -MQTT Callback Thread: - handleMovingObjectMessage() - --> cache_manager.sceneWithCameraID(id) - --> checkRefresh() - --> refreshScenes() - --> data_source.getScenes() <-- HTTP call! - --> blocks waiting for response - --> paho network loop is THIS thread - --> DEADLOCK: HTTP response can't arrive - because paho can't read the socket -``` - -### 5.2 Lock-Free HTTP Architecture - -`cache_manager.py:37-112` - -`refreshScenes()` is redesigned into 3 phases that never hold the lock during -HTTP: - -```python -def refreshScenes(self): - # Phase 1: HTTP fetch OUTSIDE lock (lines 50-60) - try: - result = self.data_source.getScenes() # HTTP, no lock held - except requests.exceptions.Timeout: - log.error("[CACHE_REFRESH_TIMEOUT] ...") - return # Graceful: use stale cache - - # Phase 2: Camera param sync OUTSIDE lock (lines 68-71) - for scene_data in found: - self._refreshCameras(scene_data) # HTTP, no lock held - - # Phase 3: In-memory cache update INSIDE lock (lines 73-112) - with self._lock: # Fast: dict ops only - for scene_data in found: - self.cached_scenes_by_uid[uid] = scene - self._cached_scenes_by_cameraID[cam_id] = scene -``` - -The lock (`self._lock`, `cache_manager.py:19`) is held only for fast dictionary -updates. HTTP work completes before the lock is acquired. - -### 5.3 Fast Lookup Methods - -`cache_manager.py:271-287` - -New `_fast` suffixed methods do dict-only lookups — safe to call from the MQTT -callback thread: - -```python -def sceneWithCameraID_fast(self, cameraID): # Line 271 — dict-only, no HTTP -def sceneWithSensorID_fast(self, sensorID): # Line 275 — dict-only, no HTTP -def sceneWithID_fast(self, sceneID): # Line 279 — dict-only, no HTTP -def sceneWithRemoteChildID_fast(self, childID): # Line 285 — dict-only, no HTTP -``` - -All MQTT callback thread code uses `_fast` methods exclusively. - -### 5.4 Background Periodic Refresh - -`cache_manager.py:289` - -```python -def startPeriodicRefresh(self, interval=None): - """Start daemon thread that refreshes cache every 60 seconds.""" -``` - -Replaces on-demand `checkRefresh()` that blocked the MQTT thread. The interval -is controlled by `REFRESH_TIME = 60` (`cache_manager.py:14`). Cache freshness -is now decoupled from the message processing hot path. - -### 5.5 Cache Invalidation Safety - -`cache_manager.py:323-328` - -`invalidate()` now clears all lookup dicts under the lock, so `_fast` methods -don't return stale results: - -```python -def invalidate(self): - with self._lock: - self.cached_scenes_by_uid = None - self._cached_scenes_by_cameraID = {} # Clear stale lookups - self._cached_scenes_by_sensorID = {} # Clear stale lookups -``` - -### 5.6 Null Safety in refreshScenesForCamParams - -`cache_manager.py:155-156` - -After `invalidate()`, `cached_scenes_by_uid` is `None`. Added guard to prevent -`AttributeError: 'NoneType' object has no attribute 'values'`: - -```python -with self._lock: - if self.cached_scenes_by_uid is None: - return -``` - -### 5.7 Camera Refresh Distortion Null Guard - -`cache_manager.py:125-132` - -`_refreshCameras()` assumed `camera_parameters[uid].get('distortion')` always -returned a dict, but it can be `None` if distortion data hasn't been sent yet. - -```python -# Before: -distortion_values = { - dist_coeff: self.camera_parameters[camera['uid']].get('distortion')[dist_coeff] - # Crashes if None ^ -} - -# After: -distortion = self.camera_parameters[camera['uid']].get('distortion') -if distortion is not None: - distortion_values = { - dist_coeff: distortion.get(dist_coeff) - for dist_coeff in supported_distortion_values - } -``` - ---- - -## 6. Scene-Aware Time Chunking - -`time_chunking.py` - -### 6.1 The Problem - -The baseline `TimeChunkBuffer` grouped frames per-camera with no scene context: - -``` -Baseline TimeChunkBuffer: - {category: {camera_id: (objects, when, already_tracked)}} - - Timer fires every 50ms --> dispatch ALL buffered cameras - No concept of scene grouping - Cameras from different scenes could be batched together - time.sleep() drifts under load -``` - -### 6.2 Scene-Aware Two-Level Buffer - -`time_chunking.py:86` - -```python -class SceneAwareCategoryBuffer: -``` - -Two-level dictionary structure (`time_chunking.py:116`): - -```python -# {scene_id: {camera_id: (objects, when, already_tracked, arrival_monotonic)}} -self._data: Dict[str, Dict[str, tuple]] = defaultdict(dict) -``` - -Three key methods: - -| Method | Line | Purpose | -|--------|------|---------| -| `update()` | 120 | Store latest frame per camera, grouped by scene. Overwrites previous. | -| `pop_complete_scenes()` | 143 | Returns scenes where all cameras have arrived (event-driven fast path). | -| `pop_stale_scenes()` | 161 | Returns scenes older than timeout (timer fallback for partial scenes). | - -### 6.3 Event-Driven Dispatch - -`time_chunking.py:120-141` - -When `update()` stores a frame and the scene reaches its expected camera count, -it fires `on_scene_complete` — but only AFTER releasing the buffer lock: - -```python -def update(self, camera_id, scene_id, objects, when, already_tracked): - notify = False - arrival = time.monotonic() - with self._lock: - self._data[scene_id][camera_id] = (objects, when, already_tracked, arrival) - if expected is not None and len(self._data[scene_id]) >= expected: - notify = True - # Notify OUTSIDE lock to prevent deadlock - if notify and self._on_scene_complete is not None: - self._on_scene_complete() -``` - -**Lock ordering:** `_lock` is released before `on_scene_complete` acquires -`_dispatch_condition`. This prevents `buffer._lock → _dispatch_condition` -conflicting with `_dispatch_condition → buffer._lock` in the dispatch path. - -### 6.4 Camera Count Resolution - -`time_chunking.py:62-84` - -The expected camera count per scene is derived dynamically from CacheManager: - -```python -# time_chunking.py:62 -def set_cache_manager(cache_manager): - global _cache_manager - _cache_manager = cache_manager - -# time_chunking.py:67-84 -def _get_scene_camera_count(scene_id): - scene = _cache_manager.sceneWithID_fast(scene_id) # Line 79 - if scene is not None and hasattr(scene, 'cameras'): - count = len(scene.cameras) - if count > 0: - return count - return None -``` - -Uses `_fast` (dict-only) lookup — safe to call from any thread without -triggering HTTP. - -### 6.5 Hybrid Dispatch Model - -`time_chunking.py:192` - -```python -class TimeChunkProcessor(threading.Thread): -``` - -Dispatch priority: -1. **Complete scenes** (all cameras arrived) → immediate dispatch via - `threading.Condition` early wake -2. **Scheduled timer** (200ms) → dispatch complete + stale partial scenes -3. **Stale timeout** → partial scenes that waited too long - -Fixed-rate scheduling via `time.monotonic()` (`time_chunking.py:292, 295, 310`): - -```python -# time_chunking.py:292 -next_scheduled = time.monotonic() + self.interval_sec - -# Drift detection and correction (lines 322-328): -# If system fell behind by >1 interval, skip forward to prevent burst dispatches -``` - -### 6.6 Unit Tests - -`test_time_chunking.py` — 371 lines covering: -- SceneAwareCategoryBuffer overwrite semantics -- Scene completion detection with dynamic camera count -- Stale scene timeout dispatch -- Hybrid dispatch priority ordering - ---- - -## 7.
