Project Description

libfyaml is a modern alternative to libyaml that passes all current YAML 1.2 tests from the official YAML Test Suite, see the matrix.

It has a similar event based parser interface, so switching from libyaml to libfyaml shouldn't be hard.

Goal for this Hackweek

I already started packaging libfyaml here: https://build.opensuse.org/package/show/home:tinita:branches:devel:libraries:c_c++/libfyaml

But certain things are missing.

Goal: Get it ready and submit it to d:l:c and hopefully Factory.

    Create object oriented API for perl's YAML::XS module, with YAML 1.2 Support by tinita

    Description

    YAML::XS is a binding to libyaml and already quite old, but the most popular YAML module for perl. There are two main issues:

    • It uses global package variables to influence behaviour.
    • It didn't implement the loading of types like numbers and booleans according to the YAML spec (neither 1.1 nor 1.2).

    Goals

    Create a new interface which works object oriented. Currently YAML::XS exports a list of functions.

    • The new API will allow to create a YAML::XS object containing configuration influencing the behaviour of loading and dumping.
      • It keeps the libyaml parser and emitter structs in memory, so repeated calls can save the creation of those structs
    • It will by default implement the YAML 1.2 Core Schema, so it is compatible to other YAML processors in perl and in other languages
    • If I have time, I would like to add the merge << key feature as an option. We could then use it in openQA as a replacement for YAML::PP to be faster.

    I already created a proof of concept with a minimal functionality some weeks before this HackWeek.

    ESETv2 Emulator / interpreter by m.crivellari

    Description

    ESETv2 is an intriguing challenge developed by ESET, available on their website under the "Challenge" menu. The challenge involves an "assembly-like" language and a Python compiler that generates .evm binary files.

    This is an example using one of their samples (it prints N Fibonacci numbers):

    .dataSize 0
    .code
    
    loadConst 0, r1 # first
    loadConst 1, r2 # second
    
    loadConst 1, r14 # loop helper
    
    consoleRead r3
    
    loop:
        jumpEqual end, r3, r15
    
        add r1, r2, r4
        mov r2, r1
        mov r4, r2
    
        consoleWrite r1
    
        sub r3, r14, r3
        jump loop
    end:
    hlt
    

    This language also supports multi-threading. It includes instructions such as createThread to start a new thread, joinThread to wait until a thread completes, and lock/unlock to facilitate synchronization between threads.

    Goals

    • create a full interpreter able to run all the available samples provided by ESET.
    • improve / optimize memory (eg. using bitfields where needed as well as avoid unnecessary memory allocations)

    Resources

    Achivements

    Project still not complete. Added lock / unlock instruction implementation but further debug is needed; there is a bug somewhere. Actually the code it works for almost all the examples in the samples folder. 1 of them is not yet runnable (due to a missing "write" opcode implementation), another will cause the bug to show up; still not investigated, anyhow.


    Add a machine-readable output to dmidecode by jdelvare

    Description

    There have been repeated requests for a machine-friendly dmidecode output over the last decade. During Hack Week 19, 5 years ago, I prepared the code to support alternative output formats, but didn't have the time to go further. Last year, Jiri Hnidek from Red Hat Linux posted a proof-of-concept implementation to add JSON output support. This is a fairly large pull request which needs to be carefully reviewed and tested.

    Goals

    Review Jiri's work and provide constructive feedback. Merge the code if acceptable. Evaluate the costs and benefits of using a library such as json-c.


    FizzBuzz OS by mssola

    Project Description

    FizzBuzz OS (or just fbos) is an idea I've had in order to better grasp the fundamentals of the low level of a RISC-V machine. In practice, I'd like to build a small Operating System kernel that is able to launch three processes: one that simply prints "Fizz", another that prints "Buzz", and the third which prints "FizzBuzz". These processes are unaware of each other and it's up to the kernel to schedule them by using the timer interrupts as given on openSBI (fizz on % 3 seconds, buzz on % 5 seconds, and fizzbuzz on % 15 seconds).

    This kernel provides just one system call, write, which allows any program to pass the string to be written into stdout.

    This project is free software and you can find it here.

    Goal for this Hackweek

    • Better understand the RISC-V SBI interface.
    • Better understand RISC-V in privileged mode.
    • Have fun.

    Results

    The project was a resounding success add-emoji Lots of learning, and the initial target was met.


    FastFileCheck work by pstivanin

    Description

    FastFileCheck is a high-performance, multithreaded file integrity checker for Linux. Designed for speed and efficiency, it utilizes parallel processing and a lightweight database to quickly hash and verify large volumes of files, ensuring their integrity over time.

    https://github.com/paolostivanin/FastFileCheck

    Goals

    • Release v1.0.0

    Design overwiew:

    • Main thread (producer): traverses directories and feeds the queue (one thread is more than enough for most use cases)
    • Dedicated consumer thread: manages queue and distributes work to threadpool
    • Worker threads: compute hashes in parallel

    This separation of concerns is efficient because:

    • Directory traversal is I/O bound and works well in a single thread
    • Queue management is centralized, preventing race conditions
    • Hash computation is CPU-intensive and properly parallelized

    A CLI for Harvester by mohamed.belgaied

    [comment]: # Harvester does not officially come with a CLI tool, the user is supposed to interact with Harvester mostly through the UI [comment]: # Though it is theoretically possible to use kubectl to interact with Harvester, the manipulation of Kubevirt YAML objects is absolutely not user friendly. [comment]: # Inspired by tools like multipass from Canonical to easily and rapidly create one of multiple VMs, I began the development of Harvester CLI. Currently, it works but Harvester CLI needs some love to be up-to-date with Harvester v1.0.2 and needs some bug fixes and improvements as well.

    Project Description

    Harvester CLI is a command line interface tool written in Go, designed to simplify interfacing with a Harvester cluster as a user. It is especially useful for testing purposes as you can easily and rapidly create VMs in Harvester by providing a simple command such as: harvester vm create my-vm --count 5 to create 5 VMs named my-vm-01 to my-vm-05.

    asciicast

    Harvester CLI is functional but needs a number of improvements: up-to-date functionality with Harvester v1.0.2 (some minor issues right now), modifying the default behaviour to create an opensuse VM instead of an ubuntu VM, solve some bugs, etc.

    Github Repo for Harvester CLI: https://github.com/belgaied2/harvester-cli

    Done in previous Hackweeks

    • Create a Github actions pipeline to automatically integrate Harvester CLI to Homebrew repositories: DONE
    • Automatically package Harvester CLI for OpenSUSE / Redhat RPMs or DEBs: DONE

    Goal for this Hackweek

    The goal for this Hackweek is to bring Harvester CLI up-to-speed with latest Harvester versions (v1.3.X and v1.4.X), and improve the code quality as well as implement some simple features and bug fixes.

    Some nice additions might be: * Improve handling of namespaced objects * Add features, such as network management or Load Balancer creation ? * Add more unit tests and, why not, e2e tests * Improve CI * Improve the overall code quality * Test the program and create issues for it

    Issue list is here: https://github.com/belgaied2/harvester-cli/issues

    Resources

    The project is written in Go, and using client-go the Kubernetes Go Client libraries to communicate with the Harvester API (which is Kubernetes in fact). Welcome contributions are:

    • Testing it and creating issues
    • Documentation
    • Go code improvement

    Harvester CLI might be interesting to you if you want to learn more about:
