MyGitServer is a simplified local Git server implementation using Go that replicates essential Git features like initializing repositories, branching, committing, merging, and conflict resolution. It focuses on core version control operations without external services or authentication. The system stores its data in the ".mygitserver" directory and simulates Git's behavior for tracking branches, commits, and file states. The server is optimized using Go’s concurrency mechanisms, like goroutines and mutexes, ensuring high performance and scalability. Features include branching, interactive rebasing, and conflict resolution, with clear user prompts and manual conflict handling. Future enhancements could include tagging and remote repository integration.
