omnilock

A zero dependency locker.

How does it work?

This locker uses TCP connections to keep track of locks. This way, a lock is freed as soon as the locking process ends (some way or another) or it's unlocked explicitly.

Protocol

1. Open a TCP connection to the omnilock server
2. Send a lock command through the established connection (e.g. lock my_lock)
3. Read the response, it may be either success, failed or error: something went wrong
4. Do your things on the client side
5. Either unlock the lock explicitly: unlock my_lock or just let the process exit so the OS closes the connection

Note: All commands and responses end with \n (newline).

Usage as docker image

Start the server with:

docker run --rm -it -p 7194:7194 ghcr.io/nitwhiz/omnilock:latest

And connect to it via port 7194.
