Implement pure Go Git HTTP server without CLI dependencies 
Major rewrite to eliminate git CLI dependency:
- Created object package for Git object format handling (blob, tree, commit)
- Implemented packfile generation from scratch
- Rewrote repo initialization to create Git repos without CLI
- Implemented git-upload-pack protocol in pure Go
- Updated all server handlers to use new implementation
- Added Git packet tracing to test.sh for debugging
- Fixed tests to work with new implementation

The server now works entirely with Go code, no git commands needed.
Clone operations work correctly, but pull operations still have protocol
negotiation issues that need further debugging.

Infinite Git

A Git HTTP server that generates a new commit every time someone pulls from the repository.

Features

  • Implements Git smart HTTP protocol for read-only access
  • Generates a unique commit on every pull/clone operation
  • Thread-safe commit generation
  • Persistent Git repository on disk
  • Structured logging with slog

Installation

go install github.com/imjasonh/infinite-git/cmd/infinite-git@latest

Or build from source:

git clone https://github.com/imjasonh/infinite-git
cd infinite-git
go build -o infinite-git ./cmd/infinite-git

Usage

Start the server:

infinite-git

Configuration via environment variables:

  • PORT: HTTP server port (default: "8080")
  • REPO_PATH: Path to Git repository (default: "./infinite-repo")

Example:

PORT=3000 REPO_PATH=/tmp/my-infinite-repo infinite-git

Logging is configured via the standard clog environment variables.

Testing

Clone the repository:

git clone http://localhost:8080

Every time you pull, you'll get a new commit:

cd <cloned-repo>
git pull origin main
# New commit appears!

How It Works

  1. When a client initiates a pull/clone, the server intercepts the reference discovery request
  2. Before advertising refs, it generates a new commit with:
    • A unique file containing the pull counter and timestamp
    • A commit message indicating when the pull occurred
  3. The new commit is added to the main branch
  4. The updated refs are sent to the client
  5. The client receives the new commit as part of the normal Git protocol flow

Implementation Details

  • Uses Git plumbing commands (git add, git commit) to create commits
  • Implements pkt-line format for Git protocol communication
  • Delegates object transfer to git upload-pack for efficiency
  • Rejects all push attempts with 403 Forbidden
