What the Watch Daemon Does

监控守护进程的功能

The watch daemon:

Scans all source files in your project
Chunks code into segments (~512 tokens)
Generates embeddings via your configured provider
Stores vectors in your configured backend
Monitors for file changes in real-time
Updates the index when files change

监控守护进程会：

扫描项目中的所有源文件
拆分代码为片段（约512个tokens）
生成嵌入向量（通过你配置的提供商）
存储向量到你配置的后端
实时监控文件变更
文件变更时更新索引

Debounce Explained

防抖机制说明

When you save a file, editors often write multiple times quickly. Debouncing waits for changes to settle:

Value	Behavior
`100`	More responsive, more reindexing
`500`	Balanced (default)
`1000`	Less responsive, fewer reindexing

当你保存文件时，编辑器通常会快速多次写入。防抖机制会等待变更稳定后再处理：

数值	行为
`100`	响应更快，重新索引更频繁
`500`	平衡模式（默认）
`1000`	响应较慢，重新索引次数更少

Initial Indexing

初始索引

What Gets Indexed

索引范围

The daemon indexes files:

Matching supported extensions (.go, .js, .ts, .py, etc.)
Not in ignore patterns (node_modules, .git, etc.)
Respecting
```
.gitignore
```

守护进程会索引以下文件：

匹配支持的扩展名（.go、.js、.ts、.py等）
不在忽略规则内（node_modules、.git等）
遵循
```
.gitignore
```
配置

Indexing Progress

索引进度

Large codebases show progress:

Scanning files...
Found 10,245 files
Processing chunks...
████████████████░░░░░░░░░░░░░░░░ 50% (5,122/10,245)

大型代码库会显示进度：

正在扫描文件...
找到10,245个文件
正在处理代码片段...
████████████████░░░░░░░░░░░░░░░░ 50% (5,122/10,245)

Indexing Time Estimates

索引时间预估

Codebase	Files	Time (Ollama)	Time (OpenAI)
Small	100	~30s	~10s
Medium	1,000	~5min	~1min
Large	10,000	~30min	~5min

代码库规模	文件数	耗时（Ollama）	耗时（OpenAI）
小型	100	~30秒	~10秒
中型	1,000	~5分钟	~1分钟
大型	10,000	~30分钟	~5分钟

Real-Time Monitoring

实时监控

After initial indexing, the daemon watches for:

File creation
File modification
File deletion
File renames

初始索引完成后，守护进程会监控以下操作：

文件创建
文件修改
文件删除
文件重命名

File Change Detection

文件变更检测

Uses OS-native file watching:

macOS: FSEvents
Linux: inotify
Windows: ReadDirectoryChangesW

使用操作系统原生的文件监控机制：

macOS: FSEvents
Linux: inotify
Windows: ReadDirectoryChangesW

What Triggers Reindexing

触发重新索引的操作

Action	Result
Save existing file	Re-embed file chunks
Create new file	Index new chunks
Delete file	Remove from index
Rename file	Update path, keep vectors

操作	结果
保存现有文件	重新嵌入该文件的代码片段
创建新文件	索引新的代码片段
删除文件	从索引中移除
重命名文件	更新路径，保留向量数据

Troubleshooting

故障排查

Daemon Won't Start

守护进程无法启动

❌ Problem: "Another daemon is already running" ✅ Solution:

bash

grepai watch --stop
grepai watch --background

❌ Problem: "Config not found" ✅ Solution: Initialize first:

bash

grepai init
grepai watch

❌ Problem: "Embedder connection failed" ✅ Solution: Start your embedding provider:

bash

ollama serve  # For Ollama

❌ 问题： "Another daemon is already running"（已有另一个守护进程在运行） ✅ 解决方案：

bash

grepai watch --stop
grepai watch --background

❌ 问题： "Config not found"（未找到配置） ✅ 解决方案： 先初始化配置：

bash

grepai init
grepai watch

❌ 问题： "Embedder connection failed"（嵌入提供商连接失败） ✅ 解决方案： 启动你的嵌入提供商：

bash

ollama serve  # 针对Ollama

Indexing Issues

索引问题

❌ Problem: Files not being indexed ✅ Solution: Check ignore patterns in config, ensure file extension is supported

❌ Problem: Indexing very slow ✅ Solutions:

Use OpenAI for faster cloud embeddings
Add more ignore patterns
Increase chunking size

❌ Problem: Index seems outdated ✅ Solution: Clear and reindex:

bash

rm .grepai/index.gob
grepai watch

❌ 问题： 文件未被索引 ✅ 解决方案： 检查配置中的忽略规则，确保文件扩展名受支持

❌ 问题： 索引速度极慢 ✅ 解决方案：

使用OpenAI的云端嵌入服务以提高速度
添加更多忽略规则
增大代码片段拆分尺寸

❌ 问题： 索引内容过时 ✅ 解决方案： 清除并重新索引：

bash

rm .grepai/index.gob
grepai watch

File Watch Issues

文件监控问题

❌ Problem: Changes not detected ✅ Solutions:

Reduce debounce_ms

Check inotify limits (Linux):

bash

echo 65536 | sudo tee /proc/sys/fs/inotify/max_user_watches

❌ 问题： 变更未被检测到 ✅ 解决方案：

减小debounce_ms数值

检查inotify限制（Linux）：

bash

echo 65536 | sudo tee /proc/sys/fs/inotify/max_user_watches

Best Practices

最佳实践

Run in background: For continuous monitoring
Use workspace for monorepos: Better organization
Set up auto-start: launchd or systemd
Check logs periodically: Monitor for errors
Reindex after config changes: Especially after changing embedding model

后台运行： 用于持续监控
为单体仓库使用工作区： 更好的组织管理
配置开机自启： 使用launchd或systemd
定期查看日志： 监控错误情况
配置变更后重新索引： 尤其是在更改嵌入模型后

Status Check

状态检查

Regular health check:

bash

grepai status

Output:
