ATGardner / read-write-lock.spec.ts
Last active October 13, 2024 13:16
this is a simple Node.js TypeScript implementation of a read-write-lock using a queue, without the need for any mutex or other synchronization mechanism.
import { setTimeout } from 'node:timers/promises'
import { ReadWriteLock, ReadWriteQueueLock } from './read-write-lock'
describe('ReadWriteQueueLock', () => {
// copied test code from https://eli.thegreenplace.net/2019/implementing-reader-writer-locks/
// console.logs are useful for understanding what happens when, and making sure the lock works as expected
async function reader(lock: ReadWriteLock, id: number, data: number[]) {
await setTimeout(Math.random() * 100)
console.log(`reader ${id} locking`)

A script to convert all personal GitHub repos' default branch from 'master' to 'main'
#! /bin/bash
# The script requires jq (https://stedolan.github.io/jq/) and gh-cli (https://cli.github.com/) > 0.10
# It assumes the current user is already logged into their GitHub account, and that they have SSH access set up
# with `gh config set git_protocol ssh`
#
# The script goes over all (up to 100) personal, non-archived, non-forked repositories, that currently has 'master' as
# their default branch and replaces it with NEW_DEFAULT (defined as 'main', but can be easily changed)
#
# It clones a new local repo from each one, creates a NEW_DEFAULT branch in it, pushes it, and also sets it as the
