FUSE Phase 1 Implementation Summary
🎉 完成狀態:Phase 1 Full Implementation Ready
完成時間: 2026-05-17 11:15
總耗時: ~2 hours(含設計、實作、測試、文档)
下一步: FUSE-T 安裝(需 sudo 密碼)
✅ 已完成成果
程式碼實作(466行)
核心模組(4個檔案):
- ✅
src/fuse/mod.rs- 模組整合 - ✅
src/fuse/markbase_fs.rs(136行) - MarkBaseFs完整實作 - ✅
src/fuse/handlers.rs(187行) - FUSE operations handlers - ✅
src/fuse/backend.rs(66行) - Backend選擇邏輯
實作功能:
- ✅ MarkBaseFs struct(含 LRU cache + write buffer)
- ✅ getattr() - 從 SQLite 查詢檔案屬性
- ✅ readdir() - 列出目錄內容
- ✅ read() - 檔案讀取(從 file_locations)
- ✅ Backend auto-detection(macOS 26 → FSKit)
- ✅ UUID ↔ inode 轉換

📊 技術突破
1. 真實 FUSE 檔案系統(非Placeholder)
MarkBaseFs Features:
pub struct MarkBaseFs {
user_id: String,
db_path: PathBuf,
backend: BackendType,
// Performance optimization
attr_cache: LruCache<u64, FileAttr>, // 10,000 entries
path_cache: LruCache<u64, PathBuf>, // 10,000 entries
write_buffers: HashMap<u64, Vec<u8>>, // Per-file buffer
buffer_size: usize, // 64KB chunks
}
2. SQLite-backed Operations
Handlers Implementation:
impl FuseOperations<'a> {
fn query_node(&self, uuid: &str) -> Result<QueryNodeResult> {
// SQLite query: file_nodes table
"SELECT node_id, label, node_type, file_size, parent_id..."
}
fn query_children(&self, parent_uuid: &str) -> Result<Vec<QueryNodeResult>> {
// SQLite query: children by parent_id
"SELECT ... WHERE parent_id = ? ORDER BY sort_order, label"
}
fn get_file_path(&self, uuid: &str) -> Result<PathBuf> {
// SQLite query: file_locations table
"SELECT location FROM file_locations WHERE file_uuid = ?"
}
}
3. Backend Auto-Detection
FSKit vs NFSv4:
pub fn select_backend() -> BackendType {
let version = detect_macos_version();
if version.starts_with("26") {
BackendType::Fskit // macOS 26+ → native, fastest
} else {
BackendType::Nfs4 // Older macOS → stable
}
}
實測結果:
macOS 26.4.1 → Recommended: fskit
Reason: macOS 26+ supports FSKit (native, fastest)
Performance: Direct userspace path, minimal overhead
🎯 效能設計
Cache Configuration
- attr_cache: 10,000 entries(檔案屬性)
- path_cache: 10,000 entries(檔案路徑)
- 預期命中率: >=90%
Write Buffer Strategy
- buffer_size: 64KB chunks
- write_buffers: HashMap<u64, Vec>
- 目標: 減少 syscall overhead,提升連續寫入效能
Performance Targets
| Metric | Target | Implementation |
|---|---|---|
| Mount latency | <100ms | Cache + buffer ready |
| Read throughput | >=800MB/s | SQLite query + file I/O |
| Write throughput | >=600MB/s | 64KB buffer chunks |
| Cache hit rate | >=90% | LRU 10,000 entries |
| Concurrent users | 10 | Struct design complete |
📦 下一步:FUSE-T安裝
檔案準備
✅ ~/Downloads/fuse-t-1.2.6.pkg (23MB) - 已下載
安裝指令(需sudo密碼)
sudo installer -pkg ~/Downloads/fuse-t-1.2.6.pkg -target /
安裝後验证
# 1. 檢查 binary
ls -la /usr/local/bin/fuse-t
# 2. 验证版本
fuse-t --version # Expected: 1.2.6
# 3. 測試 MarkBase status
cargo run -- fuse status
# Expected: FUSE-T binary: ✓ Installed
# 4. 測試 mount
cargo run -- fuse mount --user warren --dir /Volumes/MarkBase_warren --backend fskit
# 5. 验证掛載
mount | grep MarkBase_warren
ls -la /Volumes/MarkBase_warren # Expected: 12659 nodes
