About

This is my attempt at creating a version control similar to git and is still currently in development, created from scratch in C++. Features functionalities like status, commit, push and log.
NOTE: This will work only on Linux and Unix systems and does not support Windows for now. This uses the C++17 standard.

Demo:

Getting Started

Clone the repository

https://github.com/shadyskies/vcs_from_scratch.git

Prerequisites

Sqlite3, g++-9 should be installed.

Installing

Build the main file.

g++ -std=c++17 client.cpp file.cpp -lsqlite3 -o file.out

And on the remote server.

g++ -std=c++17 server.cpp -o server.out

Change the host IP in server.cpp to match server IP.

Usage

Run commands as you normally would with git.

./file.out < status / commit <message> / push(requires server to be running) / log >

Run the server(Tested on docker container)

./server.out 

TODO :

• figure out database
• figure out files diff
• diff code for remote vs local
• test in docker
• garbage values in end of file (check bytes written)
• diff bw server and client
• listen for incoming connections after one client closes
• add commit hash
• where does HEAD for local point wrt remote?
• multiple clients? (data inconsistency)
• package code

Future Scopes :

• Branching
• Revert Commit
• Cherry Pick
