await-generator's Introduction

About Me

Rust: Almost all my serious personal projects are written in Rust.
Type-driven: I adopt type-driven development. I tend to express most code concepts with the type system. For example, I use newtype pattern extensively for basic numeric types, and assertions about types are expressed in wrapper types.
Plaintext only: I avoid working with files that cannot be managed by Git. This means I avoid committing images (unless they won't be modified or in SVG) into a repo, and I don't like producing multimedia.
- For documents, I use Markdown and LaTeX and generate the PDF on CI.
- For graphs, I use GraphViz and compile the image on CI.
Vim: My primary IDE is NeoVim + coc.nvim. On mobile, I develop with Vim over SSH. My setup is updated here.
Linux: My personal computer runs on Ubuntu. I use Bash as the default shell. My setup is here.
Other preferences:
- Scripting languages: Bash, Python and NodeJS.
- JVM language: Kotlin.
- Deployment: Docker on Alpine Linux image.

Personal blog

I have started jotting down some weird opinions from me in the wiki of this personal repo.

Highlighted projects

I have started a lot of open-source projects for personal interest, but many are incomplete because of lack of time and financial support. Incomplete projects are marked as ⏳.

Some of these projects were not created or maintained by me, but I included them here as I have contributed a substantial amount of code to them.

General-purpose libraries

await-generator, a PHP library that enables async/await pattern
portrait, a Rust proc-macro framework to write trait-aware proc-macro attributes such as impl-by-delegation.
dirmod, a Rust macro to smartly detect modules to include
rwlock-promise, a JavaScript library that implements mutually-exclusive and shared-exclusive locks with a Promise API
thisrc, a PHP extension that observes the refcount of the $this object without inducing side effects
xylem, a Rust framework for statetul type conversion (a post-deserialize processing stage).

I have also created numerous tiny macros and libraries in Rust, but those generally have very ad-hoc purposes and are not known to have any other users. Examples include serde-iter, count-write, xias, qualify-derive, etc.

Programming language analysis

enclavlow, my final year project that performs Java flow analysis to verify SGX data security.

Cloud native

Kelemetry, an observability tool to provide global control plane tracing for Kubernetes.
KubeAdmiral, a multi-cluster orchestrator and scheduler for Kubernetes.
KubeZoo, a lightweight multi-tenancy solution for Kubernetes.

Game development

PocketMine-MP, a reverse-engineered Minecraft server software.
- PocketMine-MP has a huge ecosystem of plugins, and most of my work in earlier years were related to developing tools and cohesion of the ecosystem, such as dependency management, build tools and common-dependency APIs.
- PocketMine-MP is an ancient project started in 2012. Some of my contributions include introducing modern tools and paradigms to the project.
- ⏳ libglocal-idea-plugin, an intellij plugin for editing libglocal language files
⏳ Traffloat, a 3D web game written in Rust.
⏳ dynec, an ECS library that focuses on type safety and optimized for specific scenarios.

Systems programming

include-flate, a Rust macro for attaching constants as deflated strings in the executable.
phar.rs, a Rust library for the PHAR (PHp ARchive) format. Also includes a WASM app and a CLI command for phar manipulation.
signed-vimrc, a vim plugin that loads PGP-signed .vimrc files in cwd
⏳ pathetique, an object-oriented abstraction of OS paths in PHP

Robotics

I was a member of the HKU Robocon Team.

Web development

⏳ octorest, generated Rust bindings for the GitHub API (can adapt to other OpenAPI implementations too)
⏳ webcord, a webapp + discord bot that mirrors a discord chat

Android development

AndTransfer, a simple Android app that shares files to any transfer.sh server.
Mentamatics, an app to train mental arithmetic calculation
MySQLClientCompact, a small MySQL browser.

Discord bots

The Discord bots I write follow minimalistic approach and rarely have sophisticated framework.

bthint, a bot that tries to extract syntactically correct code from chat messages
boredphoton, a minimalistic bot for alerting spam raids
orbs.bot, a fan project that reverse engineers the API of the webgame orbs.it and mirrors live games
⏳ blob-mirror, a bot mirroring GitHub markdown files to Discord.
⏳ webcord, a webapp + discord bot that mirrors a discord chat

Workflows are referencing vulnerable actions

Hello, there!

As part of the university research we are currently doing regarding the security of Github Actions, we noticed that one or many of the workflows that are part of this repository are referencing vulnerable versions of the third-party actions. As part of a disclosure process, we decided to open issues to notify GitHub Community.

Please note that there are could be some false positives in our methodology, thus not all of the open issues could be valid. If that is the case, please let us know, so that we can improve on our approach. You can contact me directly using an email: ikoishy [at] ncsu.edu

Thanks in advance

The workflow ci.yml is referencing action shivammathur/setup-php using references v1. However this reference is missing the commit 7163319 which may contain fix to the vulnerability.
The workflow ci.yml is referencing action shivammathur/setup-php using references v1. However this reference is missing the commit 7163319 which may contain fix to the vulnerability.
The workflow ci.yml is referencing action shivammathur/setup-php using references v1. However this reference is missing the commit 7163319 which may contain fix to the vulnerability.

The vulnerability fix that is missing by actions' versions could be related to:
(1) CVE fix
(2) upgrade of vulnerable dependency
(3) fix to secret leak and others.
Please consider updating the reference to the action.

If you end up updating the reference, please let us know. We need the stats for the paper :-)

Improve documentation

The current README is more like a guide than a documentation, and is not useful as reference if users understand a bit concept of what is attempted here. A rewrite of documentation and reference is recommended.

Ideally, there should be 3 separate articles:

Rationale of await-generator: What it is intended to do and what not
Step-by-step tutorial to transform callback style into await-generator style
Technical reference of what each yielded value does and returns

Undefined variable $name

SOFe\AwaitGenerator\AwaitException: "Unhandled async exception: Undefined variable $name" (EXCEPTION) in "/root/virions/await-generator_dev-130.phar/src/SOFe/AwaitGenerator/Await" at line 587

Channels

Unbuffered channels

class Channel<T> {
    public static function new(): array{ChannelSender<T>, ChannelReceiver<T>};
}
class ChannelSender<T> {
    public function send(T $value): Generator<void>;
}
class ChannelReceiver<T> {
    public function receive(): Generator<T>;
}

send suspends until receive is called, and receive suspends until send is called. No buffering is involved.

Buffered channels

Buffering does not affect receive logic. This can be created by wrapping ChannelSender:

class BufferedChannelSender<T> {
    public function __construct(private ChannelSender<T> $sender) {}

    public function send(T $value): void {
        Await::g2c($this->sender->send($value));
    }
}

send does not suspend. It simply spawns a background coroutine that calls send().

How to Await::ALL/Await::RACE multiple generators?

Cannot create ReflectionGenerator based on a terminated Generator

https://crash.pmmp.io/view/4142523

Cancellable interface

I don't know if "cancel" is a good term; I am not even sure if cancellation is a correct thing to do in a promise framework, where promise is just a state machine (unlike Rust futures, where you need to await a future to actually execute it).

Design

function read_line_await(LineBufReader $reader) {
    $resolve = yield Await::RESOLVE;
    $isCancelled = yield Await::IS_CANCEL;
    $reader->shiftLineCallback(function($line) use($isCancelled, $resolve) {
        if($isCancelled()) {
            $reader->unshiftLine($line);
        } else {
            $resolve($line);
        }
    });
}

When we Await::race multiple generators, the losing generators are set to be cancelled

Concerns

Coroutines are not necessarily cancellatoin-aware. They need to explicitly indicate what they do when they are cancelled (in particular, stateful promises need to reset the states they changed), which is a usability issue.

Parse Generator<mixed, mixed, mixed, T> docs and validate the type of return value

A little enhancement to help to debug and prevent unexpected behaviour. Although PHPStorm can already warn users.
