# ♻️ Rsync

> A pure TypeScript implementation of the [rsync algorithm](https://www.andrew.cmu.edu/course/15-749/READINGS/required/cas/tridgell96.pdf)

## Installation

```sh
npm install @dldc/rsync
```

## Usage

```ts
import { prepare, diff, apply } from '@dldc/rsync';

const checksum = prepare(destFile); // you can specify block size as second argument (default: 1024)
// send checksum to source
const patches = diff(sourceFile, checksum);
// send patches to dest
const syncedFile = apply(destFile, patches);
```

## Performance

This package was not designed to be fast. Since it's implemented fully in TypeScript, it's not as fast as the C implementation of rsync.
I tried to use the best practices to make it less slow but I did not benchmark it 🤷.

## Dependencies 🪶

This package has a single dependency [@dldc/erreur](https://github.com/dldc-packages/erreur) to define custom errors.

An input argument to this GitHub Action is being exported as an environment variable. If a user of this action passes untrusted input, it could be used in an insecure manner by subsequent workflow steps.

What are GitHub Actions taint flows?

GitHub Actions: Input argument exported as environment variable

An input argument to this GitHub Action is being passed back as an output. If a user of this action passes untrusted input, it could be used in an insecure manner by consuming workflows.

GitHub Actions: Input argument passed back as output

An input argument to this GitHub Action flows into a dangerous sink (such as shell command execution). This could allow a malicious user to inject commands or exploit the action.

GitHub Actions: Input argument flows to dangerous sink

A GitHub context variable (such as issue title, PR description, or comment body) is being exported as an environment variable. These context values are user-controlled and could be exploited by subsequent workflow steps.

GitHub Actions: GitHub context variable exported as environment variable

A GitHub context variable (such as issue title, PR description, or comment body) is being passed back as an output. These context values are user-controlled and could be exploited by consuming workflows.

GitHub Actions: GitHub context variable passed back as output

A GitHub context variable (such as issue title, PR description, or comment body) flows into a dangerous sink (such as shell command execution). This is a critical security issue that could allow command injection or code execution attacks.

GitHub Actions: GitHub context variable flows to dangerous sink

An environment variable flows into a dangerous sink (such as shell command execution). If this environment variable comes from an untrusted source, it could be exploited to inject commands.
