Warren	65cd68cad4	Implement incremental save for WebDAV versioning ... Changes: 1. Added dirty flag to WebDavVersioning to track unsaved changes 2. Modified create_version() to only mark dirty=true instead of immediate save_index() 3. Added flush() method to save dirty index periodically 4. Added background thread in server.rs to flush every 60 seconds 5. Async index loading on startup (spawn thread to avoid blocking OPTIONS/PROPFIND) Expected performance: - PUT operations: still fast (dirty flag only, no save_index() blocking) - Index persistence: flush every 60 seconds (or on shutdown) - OPTIONS/PROPFIND: no blocking (async index loading) Test results: - PUT (31B): 0.053s (53ms) ✅ - Index loading: async thread started ✅ - Flush thread: started but blocked by launchd auto-restart ⚠️ Next: Test flush thread in production environment (without launchd)	2026-06-30 05:29:09 +08:00
Warren	86984295bf	Fix WebDAV PUT timeout: disable versioning for user WebDAV ... Root cause: save_index() serializes entire 31KB db to JSON and writes to disk for every PUT operation (synchronous blocking call). Fix: Disabled versioning for user WebDAV by changing line 2547 from Some(versioning.clone()) to None. Performance improvement: - Before: 2+ minutes timeout - After: 10-27 milliseconds - Speedup: 12000x faster Tested: 31B, 100KB, 1MB files all upload successfully in <30ms	2026-06-30 04:56:37 +08:00

Warren	0f77983483	Implement NFS Support stub (Phase 11 P0 #3) ... NFS Support Features: - nfs_server.rs: NFSv3 server stub - nfs_server CLI tool: Port 2049, export directory - nfsserve crate dependency (v0.11.0) Implementation Status: - NfsVfsServer: Placeholder implementation - NfsConfig: Configuration struct - CLI: nfs-server command with --port, --root, --share-name Technical Details: - nfsserve crate provides NFSFileSystem trait - NFSFileSystem requires 14 async methods - Current implementation is stub (pending API study) Build: ✅ markbase-core + nfs feature Tests: 495 markbase-core (without nfs feature) Note: Full NFS server implementation requires studying nfsserve crate API (expected time: 2-3 days for 500 lines)	2026-06-24 05:42:15 +08:00
Warren	d76a200560	Add incremental backup support (Phase 8) ... BackupScheduler Enhancement: - Added incremental: bool field to BackupScheduleConfig - Default: incremental=true (enabled by default) - copy_incremental_to_snapshot() method - file_changed() detection (size + mtime comparison) - Hardlink unchanged files to base snapshot (ZFS-style) Incremental Backup Algorithm: 1. If incremental=true and previous snapshot exists: - Compare file size and mtime with base snapshot - If unchanged: create hardlink to base (zero disk usage) - If changed: copy and compress (new content) 2. If incremental=false or no previous snapshot: - Full copy (traditional backup) Storage Savings: - Unchanged files: hardlink (0 extra disk space) - Changed files: copy + compress (minimal overhead) - Similar to ZFS snapshot mechanism BackupConfigResponse Updated: - Added incremental field - Added compress field (GUI: dropdown select) Backup.vue Updated: - Incremental switch with explanation text - Compression dropdown (None/LZ4/ZSTD) - Default values loaded from backend REST API Test: curl /api/v2/backup/config {incremental:true,compress:zstd,...} Build: 495 tests pass	2026-06-24 04:20:33 +08:00
Warren	2d8e9049b0	Add compression support to backup workflow ...

Warren	55caeabd94	Add root parameter to backup/snapshot REST API ...
