# Repository Guidelines
## Project Structure & Entry Points
Meteor is split into npm workspaces plus standalone Go/Rust services. `meteor-web-backend/` (NestJS) boots from `src/main.ts` and modules under `src/devices|events|metrics`. `meteor-frontend/` (Next.js App Router) serves UI from `src/app/` with data access helpers in `src/services/`. `meteor-compute-service/` (Go) starts at `cmd/meteor-compute-service/main.go` and pushes SQS payloads through `internal/processor`. `meteor-edge-client/` (Rust) exposes the CLI in `src/main.rs`; the runtime loop lives in `Application::run` inside `src/app.rs`. Shared fixtures sit in `test-data/`, Terraform under `infrastructure/`, and long-form docs in `docs/`.
## Build & Run
- `npm run install:all` installs JS/TS workspaces; `npm run dev` launches backend (3000) and frontend (3001).
- `npm run test:backend|frontend|integration|e2e` guard merges; `npm run test:fullstack` orchestrates docker-compose suites via `docker-compose.test.yml`.
- Edge client: `cargo run -- run --camera file:meteor-edge-client/video.mp4` replays fixtures locally; use `cargo build --release` for deployment binaries.
- Compute service: `go run cmd/meteor-compute-service/main.go` and `go test ./...` before shipping changes.
- Use `./test-setup.sh` to provision LocalStack/Postgres before integration tests.
## Coding Style & Naming
TypeScript follows ESLint + Prettier (`npm run lint:*`); keep controllers/services PascalCase, providers suffixed `*.service.ts`, DTOs in `src/devices/dto/`. React components live in `src/app/<route>/` using 2-space indent and camelCase hooks. Rust adheres to `rustfmt` (`cargo fmt`) with modules snake_case; prefer `?` over `unwrap()`. Go code must pass `go fmt` and `go vet`. Avoid committing generated bundles, compiled binaries, or `tmp-home` artifacts.
## Testing Expectations
Backend uses Jest under `test/` with Supertest integration specs; keep `npm run test:cov` green. Frontend combines Jest + Testing Library with Playwright scripts in `e2e/`. Rust edge client relies on `cargo test` plus end-to-end runs such as `cargo run -- run --camera file:…`; test fixtures live in `meteor-edge-client/test-data`. Compute service needs table-driven `go test` coverage. Add regression tests alongside bug fixes.
## Commit & PR Workflow
Write imperative commits with optional scopes (`fix(edge): ...`). Reference issues in bodies, list commands executed, and attach screenshots for UI work or CLI transcripts for device flows. PRs must call out cross-service impacts and any config migrations (`migrations/` or `meteor-client-config.toml`). Wait for CI green and obtain approvals from service owners before merge.
## Security & Ops
Keep JWTs and bearer tokens in `.env` or OS keychain; never commit `meteor-client-config.toml`. Edge devices read configs from `dirs::config_dir()`—override with `HOME=<path>` when testing. Rotate credentials when sharing sample configs and scrub logs before uploading.

## Project Structure
- `meteor-frontend/` - Next.js frontend application
- `meteor-web-backend/` - NestJS backend API
- `meteor-compute-service/` - Go processing service (submodule)
- `meteor-edge-client/` - Rust edge client (submodule)
## Overview
Meteor Fullstack 是一个覆盖边缘设备、云端 API、数据处理和 Web 前端的完整流星监测网络。仓库采用 npm workspace 管理前后端，并通过 Go、Rust 等多语言组件连接实时观测、事件验证和观测结果展示。
## Testing & Integration
- Complete E2E testing framework with Playwright
- Docker-based integration testing with LocalStack
- Comprehensive test coverage for Gallery feature
## System Topology
- `meteor-edge-client/`：Rust 编写的边缘客户端 CLI（命令在 `src/main.rs`），负责摄像头采集、事件检测与上传，核心运行循环位于 `src/app.rs::Application::run`。
- `meteor-web-backend/`：NestJS Web API，入口 `src/main.ts` 启动 `AppModule`，聚合认证、设备注册、事件存取、支付与指标等子模块，持久化通过 TypeORM/PostgreSQL。
- `meteor-frontend/`：Next.js 15 应用（App Router），入口 `src/app/layout.tsx`，主要页面位于 `src/app/dashboard|gallery|analysis` 等目录，使用 React Query 与自建服务交互。
- `meteor-compute-service/`：Go 处理服务，入口 `cmd/meteor-compute-service/main.go`，从 SQS 拉取事件、执行校验并写入数据库，辅以 CloudWatch 指标与健康检查。
- `infrastructure/`：Terraform 定义 S3、SQS、CloudWatch、RDS/VPC 等资源，为各服务提供统一云端环境。
## Recent Milestone: Epic 1 Complete ✅
- ✅ Authentication system implemented
- ✅ Event upload and processing pipeline
- ✅ Gallery page with infinite scroll
- ✅ Full integration testing suite
- ✅ First Light achieved - complete data flow validated
## Execution Entry Points
- **边缘采集**：`meteor-edge-client/src/main.rs` 解析 CLI（`Run` 子命令），构造 `Application`，根据 `camera` 参数（例如 `sim:pattern:meteor`）覆盖配置并启动摄像头、检测、存储、心跳等控制器。
- **Web API**：`meteor-web-backend/src/main.ts` 通过 `NestFactory` 启动服务，`AppModule` 汇集 `devices`, `events`, `metrics` 等模块；Socket 网关与定时任务由 `ScheduleModule` 提供。
- **前端应用**：`meteor-frontend/src/app/page.tsx` 定义默认仪表盘；路由由 `app/` 目录自动生成，`services/` 封装 API 调用，`contexts/` 提供跨页面状态。
- **计算服务**：`meteor-compute-service/internal/processor` 中的 `Processor.Start` 协程消费 SQS 消息，配合 `internal/validation` 动态加载检测策略。
## Quick Start
## Data Flow Summary
1. 边缘设备通过 `meteor-edge-client run --camera …` 捕获帧，`storage` 模块归档事件，`communication` 模块将打包结果上传后端。
2. NestJS 后端在 `events` 与 `devices` 模块中接收上传，写入事件表并向 SQS 推送需要进一步分析的数据。
3. Go 计算服务从 SQS 获取消息，调用验证提供者生成分析结果，再回写数据库并发送 CloudWatch 指标。
4. 前端通过 React Query 请求 NestJS API，展示仪表盘、图库与分析视图，实现实时监控闭环。
## Development Workflow
```bash
# Development
npm run dev
# Testing
npm run install:all # 初始化依赖
npm run dev # 并行启动前端(3001)与后端(3000)
npm run test:fullstack
# Setup integration tests
./test-setup.sh
./test-setup.sh # 启动 LocalStack + 测试数据库
```
Rust 与 Go 组件分别使用 `cargo run`, `cargo test`, `go run`, `go test ./...`；详细测试矩阵参见 `TESTING.md`。
## Testing & Verification
- 前端：Jest + Testing Library (`npm run test:frontend`)，Playwright E2E (`npm run test:e2e`).
- 后端：Jest 单元与集成测试 (`npm run test:backend`, `npm run test:integration`).
- 边缘客户端：`cargo check`、`cargo test`；模拟摄像机脚本位于 `meteor-edge-client/scripts/`。
- 组合流程：`npm run test:fullstack` 调用前后端及集成测试，配合 `docker-compose.test.yml`。
## Infrastructure & Operations
- Terraform 输出的 S3/SQS/CloudWatch 资源需同步到 `.env` 与部署配置，细节参见 `infrastructure/README.md`。
- Pino + CloudWatch 提供日志链路，`metrics` 模块和 Go `metrics` 包推送业务指标。
- CI/CD 可利用 `meteor-edge-client/.github/workflows/` 示例以及 repo 根目录的 npm scripts。

# Camera Controller Module - Story 4.2 Implementation
This document describes the implementation of the Camera Controller module that captures video frames and publishes them to the event bus for real-time processing.
## Features Implemented
✅ **Event-Driven Architecture**: Camera controller runs as an independent Tokio task and communicates via the central EventBus
✅ **Configurable Frame Rate**: Supports configurable FPS (default: 30 FPS)
✅ **Multiple Input Sources**:
- Physical camera devices (requires OpenCV installation)
- Video files (requires OpenCV installation)
- **Simulated camera** (works without OpenCV - currently active)
✅ **High-Precision Timestamps**: Each frame includes precise UTC timestamps
✅ **Frame Metadata**: Each FrameCapturedEvent includes:
- Unique frame ID (auto-incrementing)
- High-precision timestamp
- Frame dimensions (width/height)
- Compressed frame data (JPEG format)
## Current Implementation: Simulated Camera
The current implementation uses a **simulated camera controller** that generates synthetic video frames. This allows the entire event-driven system to be tested without requiring OpenCV installation.
### Running the Simulated Camera
```bash
# Run the edge client with simulated camera
cargo run -- run
```
### Sample Output
```
🎯 Initializing Event-Driven Meteor Edge Client...
📊 Application Statistics:
Event Bus Capacity: 1000
Initial Subscribers: 0
🚀 Starting Meteor Edge Client Application...
✅ Received SystemStartedEvent!
🎥 Starting simulated camera controller...
Source: Device(0)
Target FPS: 30
Resolution: 640x480
📸 Received FrameCapturedEvent #1
Timestamp: 2025-07-30 17:39:35.969333 UTC
Resolution: 640x480
Data size: 115206 bytes
```
## Configuration
### App Configuration File
The camera can be configured via a TOML configuration file. The system looks for:
1. `/etc/meteor-client/app-config.toml` (system-wide)
2. `~/.config/meteor-client/app-config.toml` (user-specific)
3. `meteor-app-config.toml` (local directory)
### Sample Configuration
```toml
[camera]
source = "device" # "device" for camera, or path to video file
device_id = 0 # Camera device ID (for source = "device")
fps = 30.0 # Target frame rate
width = 640 # Frame width (optional)
height = 480 # Frame height (optional)
```
### Configuration Examples
**Physical Camera:**
```toml
[camera]
source = "device"
device_id = 0
fps = 30.0
width = 1280
height = 720
```
**Video File:**
```toml
[camera]
source = "/path/to/video.mp4"
fps = 25.0
```
## Enabling Physical Camera Support (OpenCV)
To enable real camera and video file support, you need to install OpenCV and uncomment the dependency.
### Installing OpenCV
**macOS:**
```bash
brew install opencv
```
**Ubuntu/Debian:**
```bash
sudo apt update
sudo apt install libopencv-dev clang libclang-dev
```
**Enable OpenCV in Code:**
1. Edit `Cargo.toml`, uncomment the opencv dependency:
```toml
opencv = { version = "0.88", default-features = false }
```
2. Update `src/camera.rs` to use the OpenCV implementation instead of the simulated version
## Event Structure
### FrameCapturedEvent
```rust
pub struct FrameCapturedEvent {
pub frame_id: u64, // Unique frame identifier (1-based)
pub timestamp: DateTime<Utc>, // High-precision capture timestamp
pub width: u32, // Frame width in pixels
pub height: u32, // Frame height in pixels
pub frame_data: Vec<u8>, // JPEG-encoded frame data
}
```
### Event Publishing
The camera controller publishes events to the central EventBus:
```rust
event_bus.publish_frame_captured(frame_event)?;
```
### Event Subscription
Other modules can subscribe to frame events:
```rust
let mut receiver = event_bus.subscribe();
while let Ok(event) = receiver.recv().await {
match event {
SystemEvent::FrameCaptured(frame_event) => {
println!("Frame #{}: {}x{}, {} bytes",
frame_event.frame_id,
frame_event.width,
frame_event.height,
frame_event.frame_data.len()
);
}
_ => {}
}
}
```
## Performance Considerations
- **Frame Rate Control**: Precise timing control maintains consistent FPS
- **Memory Efficient**: Frames are JPEG-compressed to reduce memory usage
- **Async Processing**: Camera runs in independent Tokio task, non-blocking
- **Configurable Buffer**: EventBus capacity can be tuned based on processing speed
## Testing
### Unit Tests
```bash
cargo test camera
```
### Integration Test
```bash
cargo run -- run
```
## Architecture Integration
The Camera Controller fits into the larger event-driven architecture:
```
┌─────────────────┐ ┌─────────────────┐ ┌─────────────────┐
│ │ │ │ │ │
│ Camera │───▶│ EventBus │───▶│ Detection │
│ Controller │ │ │ │ Module │
│ │ │ │ │ (Future) │
└─────────────────┘ └─────────────────┘ └─────────────────┘
│
▼
┌─────────────────┐
│ │
│ Storage │
│ Module │
│ (Future) │
└─────────────────┘
```
## Next Steps
With the Camera Controller implemented, the system is ready for:
1. **Detection Module**: Process frames for motion/object detection
2. **Storage Module**: Save frames and metadata to persistent storage
3. **Analytics Module**: Generate insights from captured data
4. **Network Module**: Stream/upload data to cloud services
## Troubleshooting
**"Failed to publish frame captured event"**: This is normal when no subscribers are active. The camera will continue generating frames.
**OpenCV Build Errors**: Ensure OpenCV development libraries are installed on your system before enabling the opencv dependency.
**High CPU Usage**: Reduce FPS in configuration if system resources are limited.

# - meteor_multiple.mp4 (multiple meteors)
# - background_only.mp4 (no meteors, background)
# - noise_test.mp4 (high noise conditions)
```
## Troubleshooting
### Common Issues
#### 1. "Camera source not available"
```bash
# Check if feature is enabled
cargo build --features camera_sim
# Verify source specification
cargo run --features camera_sim -- --camera-source "test:meteor" # Correct
cargo run --features camera_sim -- --camera-source "test:invalid" # Incorrect
```
#### 2. "File not found" errors
```bash
# Check file path
ls -la test_data/your_video.mp4
# Use absolute path
cargo run --features camera_sim -- --camera-source "file:/absolute/path/to/video.mp4"
```
#### 3. V4L2 device errors (Linux)
```bash
# Check if module is loaded
lsmod | grep v4l2loopback
# Load module manually
sudo modprobe v4l2loopback devices=1 video_nr=10
# Check device permissions
ls -la /dev/video*
sudo chmod 666 /dev/video10
```
#### 4. FFmpeg build errors
```bash
# Install development libraries
sudo apt-get install libavcodec-dev libavformat-dev libavutil-dev
# Or disable FFmpeg support
cargo build --features camera_sim # Without FFmpeg
```
### Performance Issues
#### High memory usage
```toml
# Reduce buffer pool size
[camera.performance]
buffer_pool_size = 10
max_camera_memory_mb = 32
```
#### Low frame rate
```bash
# Check system resources
top
htop
# Reduce resolution or frame rate
cargo run --features camera_sim -- --camera-source "test:meteor" --resolution 640x480
```
### Debugging
#### Enable debug logging
```bash
RUST_LOG=debug cargo run --features camera_sim -- --camera-source "test:meteor"
```
#### Memory leak detection
```bash
valgrind --leak-check=full ./target/debug/meteor-edge-client --camera-source "test:static"
```
#### Performance profiling
```bash
perf record ./target/release/meteor-edge-client --camera-source "test:meteor" --frames 1000
perf report
```
## Performance Optimization
### Memory Optimization
```rust
// Use smaller buffer pools for resource-constrained devices
let frame_pool = Arc::new(HierarchicalFramePool::new(8)); // Reduced from 20
// Enable memory optimization
camera_config.enable_memory_optimization = true;
camera_config.max_camera_memory = 32 * 1024 * 1024; // 32MB limit
```
### CPU Optimization
```bash
# Use release builds for performance testing
cargo build --release --features camera_sim
# Enable specific CPU features
RUSTFLAGS="-C target-cpu=native" cargo build --release --features camera_sim
```
### Network Optimization
```toml
# For network streams (future feature)
[camera.network]
buffer_size_mb = 16
connection_timeout_ms = 5000
read_timeout_ms = 1000
```
### Platform-Specific Optimizations
#### Raspberry Pi
```toml
[camera.pi]
frame_width = 1280
frame_height = 720
fps = 15.0 # Conservative for Pi
buffer_pool_size = 4
enable_memory_optimization = true
```
#### High-Performance Server
```toml
[camera.server]
frame_width = 1920
frame_height = 1080
fps = 60.0
buffer_pool_size = 32
enable_hardware_acceleration = true
```
## Best Practices
### 1. Test Data Organization
```
test_data/
├── meteors/
│ ├── bright_meteors.mp4
│ ├── faint_meteors.mp4
│ └── multiple_meteors.mp4
├── backgrounds/
│ ├── clear_sky.mp4
│ ├── cloudy_sky.mp4
│ └── high_noise.mp4
└── synthetic/
├── patterns.mp4
└── calibration.mp4
```
### 2. Configuration Management
```bash
# Environment-specific configs

meteor-client-config.prod.toml # Production
```
### 3. Continuous Validation
```bash
# Regular test suite execution
crontab -e
0 */6 * * * cd /path/to/project && scripts/test_camera_simulation.sh
```
This comprehensive guide should enable you to effectively use the camera simulation system for development, testing, and deployment of the meteor edge client.

# 内存管理优化方案
## 当前问题分析
### 1. 内存拷贝问题
当前架构中存在的主要内存问题：
```rust
// 当前实现 - 每次事件传递都会克隆整个帧数据
pub struct FrameCapturedEvent {
pub frame_data: Vec<u8>, // 640x480 RGB = ~900KB per frame
}
// 问题分析：
// - 30 FPS = 27MB/秒的内存拷贝
// - 事件总线广播时，每个订阅者都会克隆数据
// - 3个订阅者 = 81MB/秒的内存操作
```
### 2. 内存分配压力
- 每帧都需要新的内存分配
- GC压力导致延迟峰值
- 内存碎片化问题
### 3. 缓冲区管理
- Detection模块维护独立的帧缓冲
- Storage模块也有自己的缓冲
- 重复存储相同数据
## 优化方案详细设计
### 方案1: 零拷贝架构 (Zero-Copy Architecture)
#### A. 使用Arc实现共享不可变数据
```rust
use std::sync::Arc;
use bytes::Bytes;
// 新的事件结构 - 使用Arc共享数据
#[derive(Clone, Debug)]
pub struct FrameCapturedEvent {
pub frame_id: u64,
pub timestamp: chrono::DateTime<chrono::Utc>,
pub metadata: FrameMetadata,
pub frame_data: Arc<FrameData>, // 共享引用，克隆只增加引用计数
}
// 帧数据包装，包含原始数据和元信息
#[derive(Debug)]
pub struct FrameData {
pub data: Bytes, // 使用bytes crate，支持零拷贝切片
pub width: u32,
pub height: u32,
pub format: FrameFormat,
}
#[derive(Clone, Debug)]
pub struct FrameMetadata {
pub camera_id: u32,
pub exposure_time: f32,
pub gain: f32,
pub temperature: Option<f32>,
}
#[derive(Clone, Debug)]
pub enum FrameFormat {
RGB888,
YUV420,
JPEG,
H264Frame,
}
// 实现示例
impl FrameCapturedEvent {
pub fn new_zero_copy(
frame_id: u64,
data: Vec<u8>,
width: u32,
height: u32,
) -> Self {
let frame_data = Arc::new(FrameData {
data: Bytes::from(data), // 转换为Bytes，之后可零拷贝切片
width,
height,
format: FrameFormat::RGB888,
});
Self {
frame_id,
timestamp: chrono::Utc::now(),
metadata: FrameMetadata::default(),
frame_data,
}
}
// 获取帧数据的只读引用
pub fn data(&self) -> &[u8] {
&self.frame_data.data
}
// 创建数据的零拷贝切片
pub fn slice(&self, start: usize, end: usize) -> Bytes {
self.frame_data.data.slice(start..end)
}
}
```
#### B. 优化事件总线
```rust
use tokio::sync::broadcast;
use std::sync::Arc;
pub struct OptimizedEventBus {
// 使用Arc包装的发送器，避免克隆整个通道
sender: Arc<broadcast::Sender<Arc<SystemEvent>>>,
capacity: usize,
}
impl OptimizedEventBus {
pub fn new(capacity: usize) -> Self {
let (sender, _) = broadcast::channel(capacity);
Self {
sender: Arc::new(sender),
capacity,
}
}
// 发布事件时使用Arc包装
pub fn publish(&self, event: SystemEvent) -> Result<()> {
let arc_event = Arc::new(event);
self.sender.send(arc_event)
.map_err(|_| anyhow::anyhow!("No subscribers"))?;
Ok(())
}
// 订阅者接收Arc包装的事件
pub fn subscribe(&self) -> broadcast::Receiver<Arc<SystemEvent>> {
self.sender.subscribe()
}
}
```
### 方案2: 帧池化 (Frame Pooling)
#### A. 对象池实现
```rust
use std::sync::{Arc, Mutex};
use std::collections::VecDeque;
/// 帧缓冲池，复用内存分配
pub struct FramePool {
pool: Arc<Mutex<VecDeque<Vec<u8>>>>,
frame_size: usize,
max_pool_size: usize,
allocated_count: Arc<AtomicUsize>,
}
impl FramePool {
pub fn new(width: u32, height: u32, format: FrameFormat, max_pool_size: usize) -> Self {
let frame_size = Self::calculate_frame_size(width, height, format);
Self {
pool: Arc::new(Mutex::new(VecDeque::with_capacity(max_pool_size))),
frame_size,
max_pool_size,
allocated_count: Arc::new(AtomicUsize::new(0)),
}
}
/// 从池中获取或分配新的帧缓冲
pub fn acquire(&self) -> PooledFrame {
let mut pool = self.pool.lock().unwrap();
let buffer = if let Some(mut buf) = pool.pop_front() {
// 复用现有缓冲
buf.clear();
buf.resize(self.frame_size, 0);
buf
} else {
// 分配新缓冲
self.allocated_count.fetch_add(1, Ordering::Relaxed);
vec![0u8; self.frame_size]
};
PooledFrame {
buffer,
pool: Arc::clone(&self.pool),
frame_size: self.frame_size,
}
}
/// 计算帧大小
fn calculate_frame_size(width: u32, height: u32, format: FrameFormat) -> usize {
match format {
FrameFormat::RGB888 => (width * height * 3) as usize,
FrameFormat::YUV420 => (width * height * 3 / 2) as usize,
FrameFormat::JPEG => (width * height) as usize, // 估算
FrameFormat::H264Frame => (width * height / 2) as usize, // 估算
}
}
/// 获取池统计信息
pub fn stats(&self) -> PoolStats {
let pool = self.pool.lock().unwrap();
PoolStats {
pooled: pool.len(),
allocated: self.allocated_count.load(Ordering::Relaxed),
frame_size: self.frame_size,
}
}
}
/// RAII包装的池化帧，自动归还到池
pub struct PooledFrame {
buffer: Vec<u8>,
pool: Arc<Mutex<VecDeque<Vec<u8>>>>,
frame_size: usize,
}
impl PooledFrame {
pub fn as_slice(&self) -> &[u8] {
&self.buffer
}
pub fn as_mut_slice(&mut self) -> &mut [u8] {
&mut self.buffer
}
}
impl Drop for PooledFrame {
fn drop(&mut self) {
// 归还缓冲到池
let mut pool = self.pool.lock().unwrap();
if pool.len() < pool.capacity() {
let buffer = std::mem::replace(&mut self.buffer, Vec::new());
pool.push_back(buffer);
}
}
}
#[derive(Debug)]
pub struct PoolStats {
pub pooled: usize,
pub allocated: usize,
pub frame_size: usize,
}
```
#### B. Camera模块集成
```rust
// camera.rs 优化版本
pub struct OptimizedCameraController {
config: CameraConfig,
event_bus: EventBus,
frame_pool: FramePool,
frame_counter: AtomicU64,
}
impl OptimizedCameraController {
pub async fn capture_loop(&mut self) -> Result<()> {
loop {
// 从池中获取帧缓冲
let mut pooled_frame = self.frame_pool.acquire();
// 捕获到池化缓冲中
self.capture_to_buffer(pooled_frame.as_mut_slice()).await?;
// 转换为Arc共享数据
let frame_data = Arc::new(FrameData {
data: Bytes::from(pooled_frame.as_slice().to_vec()),
width: self.config.width.unwrap_or(640),
height: self.config.height.unwrap_or(480),
format: FrameFormat::RGB888,
});
// 创建事件
let event = FrameCapturedEvent {
frame_id: self.frame_counter.fetch_add(1, Ordering::Relaxed),
timestamp: chrono::Utc::now(),
metadata: self.create_metadata(),
frame_data,
};
// 发布事件
self.event_bus.publish(SystemEvent::FrameCaptured(event))?;
// pooled_frame 在这里自动Drop，缓冲归还到池
// 控制帧率
tokio::time::sleep(Duration::from_millis(33)).await; // ~30 FPS
}
}
}
```
### 方案3: 环形缓冲区 (Ring Buffer)
#### A. 内存映射环形缓冲
```rust
use memmap2::{MmapMut, MmapOptions};
use std::sync::atomic::{AtomicUsize, Ordering};
/// 内存映射的环形缓冲区，用于高效的帧存储
pub struct MmapRingBuffer {
mmap: Arc<MmapMut>,
frame_size: usize,
capacity: usize,
write_pos: Arc<AtomicUsize>,
read_pos: Arc<AtomicUsize>,
frame_offsets: Vec<usize>,
}
impl MmapRingBuffer {
pub fn new(capacity: usize, frame_size: usize) -> Result<Self> {
let total_size = capacity * frame_size;
// 创建临时文件用于内存映射
let temp_file = tempfile::tempfile()?;
temp_file.set_len(total_size as u64)?;
// 创建内存映射
let mmap = unsafe {
MmapOptions::new()
.len(total_size)
.map_mut(&temp_file)?
};
// 预计算帧偏移
let frame_offsets: Vec<usize> = (0..capacity)
.map(|i| i * frame_size)
.collect();
Ok(Self {
mmap: Arc::new(mmap),
frame_size,
capacity,
write_pos: Arc::new(AtomicUsize::new(0)),
read_pos: Arc::new(AtomicUsize::new(0)),
frame_offsets,
})
}
/// 写入帧到环形缓冲区
pub fn write_frame(&self, frame_data: &[u8]) -> Result<usize> {
if frame_data.len() != self.frame_size {
return Err(anyhow::anyhow!("Frame size mismatch"));
}
let pos = self.write_pos.fetch_add(1, Ordering::AcqRel) % self.capacity;
let offset = self.frame_offsets[pos];
// 直接写入内存映射区域
unsafe {
let dst = &mut self.mmap[offset..offset + self.frame_size];
dst.copy_from_slice(frame_data);
}
Ok(pos)
}
/// 读取帧从环形缓冲区（零拷贝）
pub fn read_frame(&self, position: usize) -> &[u8] {
let offset = self.frame_offsets[position % self.capacity];
&self.mmap[offset..offset + self.frame_size]
}
/// 获取当前写入位置
pub fn current_write_pos(&self) -> usize {
self.write_pos.load(Ordering::Acquire) % self.capacity
}
/// 获取可用帧数量
pub fn available_frames(&self) -> usize {
let write = self.write_pos.load(Ordering::Acquire);
let read = self.read_pos.load(Ordering::Acquire);
write.saturating_sub(read).min(self.capacity)
}
}
/// 环形缓冲区的只读视图
pub struct RingBufferView {
buffer: Arc<MmapRingBuffer>,
start_pos: usize,
end_pos: usize,
}
impl RingBufferView {
pub fn new(buffer: Arc<MmapRingBuffer>, start_pos: usize, end_pos: usize) -> Self {
Self {
buffer,
start_pos,
end_pos,
}
}
/// 迭代视图中的帧
pub fn iter_frames(&self) -> impl Iterator<Item = &[u8]> {
(self.start_pos..self.end_pos)
.map(move |pos| self.buffer.read_frame(pos))
}
}
```
#### B. Detection模块集成
```rust
// detection.rs 优化版本
pub struct OptimizedDetectionController {
config: DetectionConfig,
event_bus: EventBus,
ring_buffer: Arc<MmapRingBuffer>,
frame_metadata: Arc<RwLock<HashMap<usize, FrameMetadata>>>,
}
impl OptimizedDetectionController {
pub async fn detection_loop(&mut self) -> Result<()> {
let mut last_processed_pos = 0;
loop {
let current_pos = self.ring_buffer.current_write_pos();
if current_pos > last_processed_pos {
// 创建视图，零拷贝访问帧
let view = RingBufferView::new(
Arc::clone(&self.ring_buffer),
last_processed_pos,
current_pos,
);
// 分析帧序列
if let Some(detection) = self.analyze_frames(view).await? {
// 发布检测事件
self.event_bus.publish(SystemEvent::MeteorDetected(detection))?;
}
last_processed_pos = current_pos;
}
// 避免忙等待
tokio::time::sleep(Duration::from_millis(100)).await;
}
}
async fn analyze_frames(&self, view: RingBufferView) -> Result<Option<MeteorDetectedEvent>> {
// 使用SIMD优化的亮度计算
let brightness_values: Vec<f32> = view.iter_frames()
.map(|frame| self.calculate_brightness_simd(frame))
.collect();
// 检测算法...
Ok(None)
}
#[cfg(target_arch = "aarch64")]
fn calculate_brightness_simd(&self, frame: &[u8]) -> f32 {
use std::arch::aarch64::*;
unsafe {
let mut sum = vdupq_n_u32(0);
let chunks = frame.chunks_exact(16);
for chunk in chunks {
let data = vld1q_u8(chunk.as_ptr());
let data_u16 = vmovl_u8(vget_low_u8(data));
let data_u32 = vmovl_u16(vget_low_u16(data_u16));
sum = vaddq_u32(sum, data_u32);
}
// 累加SIMD寄存器中的值
let sum_array: [u32; 4] = std::mem::transmute(sum);
let total: u32 = sum_array.iter().sum();
total as f32 / frame.len() as f32
}
}
}
```
### 方案4: 分层内存管理
#### A. 内存层次结构
```rust
/// 分层内存管理器
pub struct HierarchicalMemoryManager {
// L1: 热数据 - 最近的帧在内存中
hot_cache: Arc<RwLock<LruCache<u64, Arc<FrameData>>>>,
// L2: 温数据 - 使用内存映射文件
warm_storage: Arc<MmapRingBuffer>,
// L3: 冷数据 - 压缩存储在磁盘
cold_storage: Arc<ColdStorage>,
// 统计信息
stats: Arc<MemoryStats>,
}
impl HierarchicalMemoryManager {
pub fn new(config: MemoryConfig) -> Result<Self> {
Ok(Self {
hot_cache: Arc::new(RwLock::new(
LruCache::new(config.hot_cache_frames)
)),

let data_clone = Arc::clone(&data);
tokio::spawn(async move {
warm_storage.write_frame(&data_clone.data).ok();
});

### 方案5: 内存监控与调优
#### A. 实时内存监控
```rust
use prometheus::{Gauge, Histogram, Counter};
pub struct MemoryMonitor {
// Prometheus metrics
memory_usage: Gauge,
allocation_rate: Counter,
gc_pause_time: Histogram,
frame_pool_usage: Gauge,
// 监控任务句柄
monitor_handle: Option<JoinHandle<()>>,
}
impl MemoryMonitor {
pub fn start(&mut self) -> Result<()> {
let memory_usage = self.memory_usage.clone();
let allocation_rate = self.allocation_rate.clone();
let handle = tokio::spawn(async move {
let mut interval = tokio::time::interval(Duration::from_secs(1));
loop {
interval.tick().await;
// 更新内存使用率
if let Ok(info) = sys_info::mem_info() {
let used_mb = (info.total - info.avail) / 1024;
memory_usage.set(used_mb as f64);
}
// 监控分配率
let allocator_stats = ALLOCATOR.stats();
allocation_rate.inc_by(allocator_stats.bytes_allocated);
}
});
self.monitor_handle = Some(handle);
Ok(())
}
/// 生成内存报告
pub fn generate_report(&self) -> MemoryReport {
MemoryReport {
current_usage_mb: self.memory_usage.get() as usize,
allocation_rate_mb_s: self.allocation_rate.get() / 1_000_000.0,
frame_pool_efficiency: self.calculate_pool_efficiency(),
recommendations: self.generate_recommendations(),
}
}
}
```

}
let traditional_time = start.elapsed();

// 测试复用
let frame1 = pool.acquire();
let addr1 = frame1.as_ptr();
drop(frame1);
let frame2 = pool.acquire();
let addr2 = frame2.as_ptr();
// 验证地址相同（复用成功）
assert_eq!(addr1, addr2);
}
}
```
这个内存优化方案将显著提升边缘设备的性能和稳定性，特别适合资源受限的树莓派环境。

## Advanced Memory Management
The meteor edge client features a sophisticated 5-phase memory optimization system designed for high-performance astronomical data processing on resource-constrained devices.
### Key Features
#### Zero-Copy Architecture (Phase 1)
- Arc-based frame sharing eliminates unnecessary memory copies
- RAII pattern ensures automatic resource cleanup
- Event-driven processing with efficient memory propagation
#### Hierarchical Frame Pools (Phase 2)
- Multiple pool sizes: 64KB, 256KB, 900KB, 2MB buffers
- Adaptive capacity management based on memory pressure (70%/80%/90% thresholds)
- Historical metrics tracking for intelligent resizing
- Cross-platform memory pressure detection
#### Advanced Streaming & Caching (Phase 3)
- Lock-free ring buffers using atomic operations (>3M frames/sec throughput)
- Memory-mapped I/O for large astronomical datasets
- Multi-level cache architecture (L1/L2/L3) with different eviction policies
- Intelligent prefetching based on access patterns
#### Production Monitoring (Phase 4)
- Real-time health check monitoring with component-level status
- Performance profiling with latency histograms (P50, P95, P99)
- Alert management with configurable thresholds
- Comprehensive diagnostics including system resource tracking
#### End-to-End Integration (Phase 5)
- Unified memory system across all components
- Camera memory integration with zero-copy capture pipeline
- Real-time meteor detection with sub-30ms processing latency
- Multi-configuration support (Raspberry Pi and high-performance servers)
### Performance Benchmarks
- **Frame Pool Operations**: >100K allocations/sec with zero memory leaks
- **Ring Buffer Throughput**: 3.6M+ writes/sec, 7.2M+ reads/sec
- **Cache Performance**: >50K lookups/sec with 80%+ hit rates
- **Memory Efficiency**: <2x growth under sustained load
- **Memory Savings**: Multi-GB savings through zero-copy architecture

## Camera Simulation for Development & Testing
The edge client includes a comprehensive camera simulation system that enables development and testing without physical camera hardware.
### Quick Start with Simulation
```bash
# Build with camera simulation support
cargo build --features camera_sim
# Run with meteor simulation
cargo run --features camera_sim -- run --camera-source "test:meteor"
# Run with video file
cargo run --features camera_sim -- run --camera-source "file:test_data/meteor_video.mp4"
```
### Available Simulation Backends
1. **Test Pattern Generator** - Synthetic patterns for deterministic testing
- Static, noise, moving bar, checkerboard, gradient
- Simulated meteor events with realistic brightness variations
2. **File Reader** - Read video files (MP4, AVI, MKV, MOV)
- Loop playback support
- Variable playback speed
- Resolution and frame rate detection
3. **V4L2 Loopback** (Linux only) - Virtual V4L2 devices
- Integration with external streaming tools
- Multi-camera simulation support
4. **FFmpeg Integration** (optional) - Enhanced video processing
- Hardware acceleration support
- Broader format compatibility
- Advanced video processing capabilities
### Detailed Documentation
For comprehensive camera simulation documentation, see:
- [CAMERA_SIMULATION_USAGE.md](CAMERA_SIMULATION_USAGE.md) - Complete usage guide with examples and troubleshooting
### CI/CD Integration
The camera simulation system is designed for headless operation in CI/CD pipelines:
```bash
# Install dependencies (Ubuntu/Debian)
sudo apt-get install -y ffmpeg libavcodec-dev libavformat-dev
# Run automated tests
cargo test --features camera_sim
scripts/test_camera_simulation.sh all
```

# Edge Client Source Code Reorganization
## Summary
Successfully reorganized the meteor edge client source code from a flat structure with 35+ files in `src/` into a well-organized modular structure with 7 functional domains.

## Benefits
1. **Clear Module Boundaries**: Each directory represents a distinct functional domain
2. **Better Organization**: Related code is grouped together
3. **Easier Navigation**: Developers can quickly locate relevant code
4. **Scalability**: Easy to add new features within appropriate modules
5. **Maintainability**: Reduced cognitive load when working on specific features
6. **Test Organization**: Tests are co-located with the code they test
## Changes Made
### File Movements
- **Core modules**: app, config, events, logging → `core/`
- **Memory management**: 8 modules + 6 test files → `memory/` and `memory/tests/`
- **Detection**: detection.rs → `detection/detector.rs`, plus 2 related files
- **Network**: api, communication, websocket, log_uploader → `network/`
- **Device**: registration, hardware_fingerprint → `device/`
- **Monitoring**: production_monitor, integrated_system → `monitoring/`
- **Storage**: storage.rs → `storage/`
- **Tests**: integration_test.rs → `tests/`
### Import Path Updates
All `use crate::` imports were systematically updated to reflect new module paths:
- `crate::api::` → `crate::network::api::`
- `crate::frame_pool::` → `crate::memory::frame_pool::`
- `crate::detection::` → `crate::detection::detector::`
- etc.
### Module Exports
Created `mod.rs` files for each new module with appropriate re-exports to maintain clean public APIs.
## Known Issues
The following pre-existing code issues were identified but not fixed (unrelated to reorganization):
1. **Detection/Monitoring modules**: Have some logic errors (9 compile errors)
- Type mismatches in `integrated_system.rs`
- Missing method implementations
- Borrowed value issues
2. **Log Uploader**: Temporarily disabled due to missing `LogFileManager` and `StructuredLogger` types
These issues existed before the reorganization and should be addressed separately.
## Compilation Status
- ✅ **test-fingerprint** binary: Compiles successfully
- ⚠️ **Main binary**: Has 9 pre-existing logic errors (not from reorganization)
- ✅ **Module structure**: All imports and paths correctly updated
## Next Steps
1. Fix the 9 logic errors in detection/monitoring modules
2. Implement missing logging infrastructure (LogFileManager, StructuredLogger)
3. Re-enable log_uploader module
4. Run full test suite to verify functionality
## Statistics
- **Before**: 35+ files in flat `src/` directory
- **After**: 41 files organized into 11 directories
- **Modules created**: 8 new module directories with `mod.rs` files
- **Files moved**: 35 files
- **Import paths updated**: ~100+ import statements
