Complete Implementation Plan for Onyx Phase 1

Milestone 2: Transparent Versioning and onx save ✓ COMPLETED

Filesystem Daemon Implementation

21. ✓ Create daemon structure (internal/daemon/daemon.go)

    • Implemented Daemon struct with repo, watcher, ticker, debounce, and shutdown channels
    • Added configuration support with Config struct
    • Implemented Start(), Stop(), and IsRunning() methods
    • Includes main event loop with proper goroutine management

22. ✓ Implement filesystem watching (internal/daemon/watcher.go)

    • Initialized fsnotify watcher
    • Added repository root to watch list with recursive directory walking
    • Implemented recursive subdirectory watching
    • Filtered out .git, .onx, and other ignored directories
    • Implemented debouncing (500ms default, configurable)

23. ✓ Implement snapshot algorithm (internal/daemon/snapshot.go)

    • Implemented CreateSnapshot() with full workflow:
      1. Read current workspace pointer from .onx/workspace
      2. Create tree from working directory state
      3. Create ephemeral commit with auto-generated message
      4. Update refs/onyx/workspaces/current reference
      5. Update .onx/workspace pointer with latest state
    • Added workspace state serialization/deserialization

24. ✓ Create daemon entry point (cmd/onxd/main.go)

    • Implemented command-line interface with cobra
    • Parse command line flags (repo path, interval, debounce)
    • Initialize daemon with configuration
    • Set up signal handlers (SIGTERM, SIGINT) for graceful shutdown
    • Run main loop with PID file management

25. ✓ Implement daemon control (internal/commands/daemon.go)

    • onx daemon start - Start background daemon with process detachment
    • onx daemon stop - Stop daemon gracefully using SIGTERM
    • onx daemon status - Check daemon status via PID file
    • PID file management in .onx/daemon.pid
    • Process lifecycle management with proper signal handling

onx save Command

26. ✓ Implement save command (internal/commands/save.go)

    • Implemented Save() with complete workflow:
      1. Read current ephemeral commit from refs/onyx/workspaces/current
      2. Create new commit with user-provided message
      3. Determine next branch number based on workstream commit count
      4. Create branch ref (refs/onyx/workstreams/{name}/commit-{n})
      5. Update workstreams.json with new commit metadata
      6. Log to oplog via transaction support
    • Integrated with existing workstream model
    • Added transaction support for undo capability

27. ✓ Add message validation

    • Require non-empty message (enforced by cobra flag)
    • Validate message length (max 72 chars for title)
    • Support multi-line messages with -m flag
    • Proper error messages for validation failures

Implementation Summary

All components of Milestone 2 have been successfully implemented:

• Daemon: Full filesystem monitoring with fsnotify, debouncing, and automatic snapshots
• Save Command: Complete integration with workstreams and oplog
• Infrastructure: PID file management, signal handling, transaction support
• Testing: All existing tests pass, binaries build successfully

The implementation provides a solid foundation for transparent versioning in Onyx.
