Project Description
For a few months, openSUSE community has the ability to host the openSUSE rpm repositories on a commercial CDN and it is in a slowly rolling out phase. There are however remaining potential bottlenecks and optimisation opportunities. My goal for this hack week is to investigate them and make reasonable progress on resolving them.
Topics that are in scope and being investigated:
- Switch of repository metadata from gzip to the more modern (faster to decompress, smaller sizes) zstd
- investigate zypper ref performance overheads
- Understand Zsync and ZChunk and benchmark for tradeoffs
- Leverage the CDN for delivering repository metadata and a mirrorlist so that the roundtrips to download.o.org can be reduced for users outside europe.
- Investigate performance of HTTP/3 to see if it would benefit us
Goal for this Hackweek
Focus on openSUSE Tumbleweed

It turns out that createrepo_c was already preparing the switch to Zstd and Zchunk, so the bulk of the work has been to fix various places in the Open Build Service and product building logic to handle that. The submissions are planned to go live on Nov 13th.
This provides overall a 10-30% reduction in download size for repository data and removes a few hundred ms in decompression time.

@mlschroe made a patch to libsolv that removes ~ 500ms from the parsing time for the tumbleweed repositories: https://github.com/openSUSE/libsolv/commit/23cbed3219bd07b5c3fa1ed8a6f2fa6c478c0fdb

I've spend several days on profiling and tuning zchunk support for the tumbleweed usecase (updating from tumbleweed snapshots) and made some upstream contributions to createrepo_c and zchunk to allow for these tunings.

@mlschroe worked on reviving zsync support in libzypp's default multicurl implementation

I've submitted necessary changes to enable curl with http/3 support. However this requires either switching to gnutls (which the security team doesn't like) or include the quictls patches for openssl. submitted the latter and waiting for maintainer review.

Create openSUSE images for Arm/RISC-V boards by avicenzi
Project Description
Create openSUSE images (or test generic EFI images) for Arm and/or RISC-V boards that are not yet supported.
Goal for this Hackweek
Create bootable images of Tumbleweed for SBCs that currently have no images available or are untested.
Consider generic EFI images where possible, as some boards can hold a bootloader.
Document in the openSUSE Wiki how to flash and use the image for a given board.
Boards that I have around and there are no images:
- Rock 3B
- Nano PC T3 Plus
- Lichee RV D1
- StartFive VisionFive (has some image needs testing)

A CLI for Harvester by mohamed.belgaied
Harvester does not officially come with a CLI tool, the user is supposed to interact with Harvester mostly through the UI. Though it is theoretically possible to use kubectl to interact with Harvester, the manipulation of Kubevirt YAML objects is absolutely not user friendly. 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.
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
