Working with GRASP Servers

GitRepublic provides minimal GRASP (Git Repository Announcement and Synchronization Protocol) interoperability for seamless compatibility with GRASP servers.

What is GRASP?

GRASP is a protocol specification for decentralized git hosting that combines git smart HTTP with Nostr relays. GRASP servers provide git repository hosting with Nostr-based announcements and state management.

GitRepublic GRASP Support

What We Support

  1. GRASP Server Detection

    • Automatically identifies GRASP servers from repository announcements
    • Uses GRASP-01 identification (clone URL pattern + matching relays tag)
    • Displays GRASP server status in clone URL reachability

  2. Clone URL Reachability

    • Tests and displays reachability status for all clone URLs
    • Shows which remotes (including GRASP servers) are accessible
    • Indicates server type (Git, GRASP)

  3. Multi-Remote Synchronization

    • When you push, automatically syncs to all remotes listed in announcement
    • Includes GRASP servers in sync operations
    • Handles sync failures gracefully

  4. Local Pull Command

    • Use gitrep pull-all --merge to fetch and merge from all remotes
    • Checks reachability first, only pulls from accessible remotes
    • Detects conflicts before merging (aborts unless --allow-conflicts)
    • Works with GRASP servers seamlessly

  5. Standard Git Operations

    • Full compatibility with GRASP servers for clone, push, pull
    • Uses standard git smart HTTP protocol
    • No special configuration needed

What We Don't Support (By Design)

  • Full GRASP-01 server compliance: We're not a full GRASP server
  • GRASP-02 proactive sync: No server-side hourly pulls (user-controlled via CLI)
  • GRASP-05 archive mode: Not implemented

Using GRASP Servers

Cloning from GRASP Servers

# Clone from a GRASP server (works just like any git server)
gitrep clone https://grasp.example.com/npub1.../repo.git

Pushing to Multiple Remotes

When your repository has both GitRepublic and GRASP servers in clone URLs:

# Push to your repo (automatically syncs to all remotes including GRASP)
gitrep push origin main

GitRepublic will:

  1. Push to the primary server
  2. Automatically sync to all other remotes (including GRASP servers)
  3. Handle sync failures gracefully

Pulling from Multiple Remotes

# Pull from all remotes including GRASP servers
gitrep pull-all --merge

This command:

  • Checks reachability of all remotes
  • Fetches from accessible remotes
  • Merges changes into your current branch
  • Detects conflicts before merging

Clone URL Reachability

View which remotes (including GRASP servers) are accessible:

  • Web Interface: Repository page shows reachability status
  • API: GET /api/repos/{npub}/{repo}/clone-urls/reachability
  • CLI: gitrep repos get <npub> <repo> shows reachability

GRASP Server Identification

GRASP servers are identified by:

  • Clone URL pattern matching GRASP conventions
  • Matching relays tag in repository announcement
  • Server response indicating GRASP support

GitRepublic automatically detects GRASP servers and displays them appropriately.

Best Practices

  1. Add GRASP servers to clone URLs: Include GRASP server URLs in your repository announcement
  2. Test reachability: Check that all remotes (including GRASP) are reachable
  3. Use pull-all: Regularly pull from all remotes to stay in sync
  4. Handle conflicts: Use --allow-conflicts if you need to proceed despite conflicts
