There is a couple of libraries available for asynchronous and non-blocking processing of HTTP requests (in Java) that can be used to avoid having threads waiting for responses in request intensive applications, for example:

The goal of this project is to get familiar with those libraries and integrate one of them with an existing HTTP client library eventually allowing for more performant and scalable applications.

The status after Hackweek 0x10 is that there is two big patches (pull requested) to bring the library more close to a 1.0.0 release:

  1. Major API cleanup
  2. Async and non-blocking HTTP backend

We could now take it from here and actually make the 1.0.0 release happening as well as an integration with Uyuni/SUSE Manager!

Looking for hackers with the skills:

    pudc - A PID 1 process that barks to the internet by mssola

    Description

    As a fun exercise in order to dig deeper into the Linux kernel, its interfaces, the RISC-V architecture, and all the dragons in between; I'm building a blog site cooked like this:

    • The backend is written in a mixture of C and RISC-V assembly.
    • The backend is actually PID1 (for real, not within a container).
    • We poll and parse incoming HTTP requests ourselves.
    • The frontend is a mere HTML page with htmx.

    The project is meant to be Linux-specific, so I'm going to use io_uring, pidfs, namespaces, and Linux-specific features in order to drive all of this.

    I'm open for suggestions and so on, but this is meant to be a solo project, as this is more of a learning exercise for me than anything else.

    Goals

    • Have a better understanding of different Linux features from user space down to the kernel internals.
    • Most importantly: have fun.

    Testing and adding GNU/Linux distributions on Uyuni by juliogonzalezgil

    Join the Gitter channel! https://gitter.im/uyuni-project/hackweek

    Uyuni is a configuration and infrastructure management tool that saves you time and headaches when you have to manage and update tens, hundreds or even thousands of machines. It also manages configuration, can run audits, build image containers, monitor and much more!

    Currently there are a few distributions that are completely untested on Uyuni or SUSE Manager (AFAIK) or just not tested since a long time, and could be interesting knowing how hard would be working with them and, if possible, fix whatever is broken.

    For newcomers, the easiest distributions are those based on DEB or RPM packages. Distributions with other package formats are doable, but will require adapting the Python and Java code to be able to sync and analyze such packages (and if salt does not support those packages, it will need changes as well). So if you want a distribution with other packages, make sure you are comfortable handling such changes.

    No developer experience? No worries! We had non-developers contributors in the past, and we are ready to help as long as you are willing to learn. If you don't want to code at all, you can also help us preparing the documentation after someone else has the initial code ready, or you could also help with testing :-)

    The idea is testing Salt (including bootstrapping with bootstrap script) and Salt-ssh clients

    To consider that a distribution has basic support, we should cover at least (points 3-6 are to be tested for both salt minions and salt ssh minions):

    1. Reposync (this will require using spacewalk-common-channels and adding channels to the .ini file)
    2. Onboarding (salt minion from UI, salt minion from bootstrap scritp, and salt-ssh minion) (this will probably require adding OS to the bootstrap repository creator)
    3. Package management (install, remove, update...)
    4. Patching
    5. Applying any basic salt state (including a formula)
    6. Salt remote commands
    7. Bonus point: Java part for product identification, and monitoring enablement
    8. Bonus point: sumaform enablement (https://github.com/uyuni-project/sumaform)
    9. Bonus point: Documentation (https://github.com/uyuni-project/uyuni-docs)
    10. Bonus point: testsuite enablement (https://github.com/uyuni-project/uyuni/tree/master/testsuite)

    If something is breaking: we can try to fix it, but the main idea is research how supported it is right now. Beyond that it's up to each project member how much to hack :-)

    • If you don't have knowledge about some of the steps: ask the team
    • If you still don't know what to do: switch to another distribution and keep testing.

    This card is for EVERYONE, not just developers. Seriously! We had people from other teams helping that were not developers, and added support for Debian and new SUSE Linux Enterprise and openSUSE Leap versions :-)

    RMT.rs: High-Performance Registration Path for RMT using Rust by gbasso

    Description

    The SUSE Repository Mirroring Tool (RMT) is a critical component for managing software updates and subscriptions, especially for our Public Cloud Team (PCT). In a cloud environment, hundreds or even thousands of new SUSE instances (VPS/EC2) can be provisioned simultaneously. Each new instance attempts to register against an RMT server, creating a "thundering herd" scenario.

    We have observed that the current RMT server, written in Ruby, faces performance issues under this high-concurrency registration load. This can lead to request overhead, slow registration times, and outright registration failures, delaying the readiness of new cloud instances.

    This Hackweek project aims to explore a solution by re-implementing the performance-critical registration path in Rust. The goal is to leverage Rust's high performance, memory safety, and first-class concurrency handling to create an alternative registration endpoint that is fast, reliable, and can gracefully manage massive, simultaneous request spikes.

    The new Rust module will be integrated into the existing RMT Ruby application, allowing us to directly compare the performance of both implementations.

    Goals

    The primary objective is to build and benchmark a high-performance Rust-based alternative for the RMT server registration endpoint.

    Key goals for the week:

    1. Analyze & Identify: Dive into the SUSE/rmt Ruby codebase to identify and map out the exact critical path for server registration (e.g., controllers, services, database interactions).
    2. Develop in Rust: Implement a functionally equivalent version of this registration logic in Rust.
    3. Integrate: Explore and implement a method for Ruby/Rust integration to "hot-wire" the new Rust module into the RMT application. This may involve using FFI, or libraries like rb-sys or magnus.
    4. Benchmark: Create a benchmarking script (e.g., using k6, ab, or a custom tool) that simulates the high-concurrency registration load from thousands of clients.
    5. Compare & Present: Conduct a comparative performance analysis (requests per second, latency, success/error rates, CPU/memory usage) between the original Ruby path and the new Rust path. The deliverable will be this data and a summary of the findings.

    dynticks-testing: analyse perf / trace-cmd output and aggregate data by m.crivellari

    Description

    dynticks-testing is a project started years ago by Frederic Weisbecker. One of the feature is to check the actual configuration (isolcpus, irqaffinity etc etc) and give feedback on it.

    An important goal of this tool is to parse the output of trace-cmd / perf and provide more readable data, showing the duration of every events grouped by PID (showing also the CPU number, if the tasks has been migrated etc).

    An example of data captured on my laptop (incomplete!!):

              -0     [005] dN.2. 20310.270699: sched_wakeup:         WaylandProxy:46380 [120] CPU:005

    Set Uyuni to manage edge clusters at scale by RDiasMateus

    Description

    Prepare a Poc on how to use MLM to manage edge clusters. Those cluster are normally equal across each location, and we have a large number of them.

    The goal is to produce a set of sets/best practices/scripts to help users manage this kind of setup.

    Goals

    step 1: Manual set-up

    Goal: Have a running application in k3s and be able to update it using System Update Controler (SUC)

    • Deploy Micro 6.2 machine
    • Deploy k3s - single node

      • https://docs.k3s.io/quick-start
    • Build/find a simple web application (static page)

      • Build/find a helmchart to deploy the application
    • Deploy the application on the k3s cluster

    • Install App updates through helm update

    • Install OS updates using MLM

    step 2: Automate day 1

    Goal: Trigger the application deployment and update from MLM

    • Salt states For application (with static data)
      • Deploy the application helmchart, if not present
      • install app updates through helmchart parameters
    • Link it to GIT
      • Define how to link the state to the machines (based in some pillar data? Using configuration channels by importing the state? Naming convention?)
      • Use git update to trigger helmchart app update
    • Recurrent state applying configuration channel?

    step 3: Multi-node cluster

    Goal: Use SUC to update a multi-node cluster.

    • Create a multi-node cluster
    • Deploy application
      • call the helm update/install only on control plane?
    • Install App updates through helm update
    • Prepare a SUC for OS update (k3s also? How?)
      • https://github.com/rancher/system-upgrade-controller
      • https://documentation.suse.com/cloudnative/k3s/latest/en/upgrades/automated.html

    Enhance setup wizard for Uyuni by PSuarezHernandez

    Description

    This project wants to enhance the intial setup on Uyuni after its installation, so it's easier for a user to start using with it.

    Uyuni currently uses "uyuni-tools" (mgradm) as the installation entrypoint, to trigger the installation of Uyuni in the given host, but does not really perform an initial setup, for instance:

    • user creation
    • adding products / channels
    • generating bootstrap repos
    • create activation keys

    Ansible to Salt integration by vizhestkov

    Description

    We already have initial integration of Ansible in Salt with the possibility to run playbooks from the salt-master on the salt-minion used as an Ansible Control node.

    In this project I want to check if it possible to make Ansible working on the transport of Salt. Basically run playbooks with Ansible through existing established Salt (ZeroMQ) transport and not using ssh at all.

    It could be a good solution for the end users to reuse Ansible playbooks or run Ansible modules they got used to with no effort of complex configuration with existing Salt (or Uyuni/SUSE Multi Linux Manager) infrastructure.

    Goals

    • [v] Prepare the testing environment with Salt and Ansible installed
    • [v] Discover Ansible codebase to figure out possible ways of integration
    • [v] Create Salt/Uyuni inventory module
    • [v] Make basic modules to work with no using separate ssh connection, but reusing existing Salt connection
    • [v] Test some most basic playbooks

      • https://docs.k3s.io/quick-start
    • Build/find a simple web application (static page)

      • Build/find a helmchart to deploy the application
    • Deploy the application on the k3s cluster

    • Install App updates through helm update

    • Install OS updates using MLM

    step 2: Automate day 1

    Goal: Trigger the application deployment and update from MLM

    • Salt states For application (with static data)
      • Deploy the application helmchart, if not present
      • install app updates through helmchart parameters
    • Link it to GIT
      • Define how to link the state to the machines (based in some pillar data? Using configuration channels by importing the state? Naming convention?)
      • Use git update to trigger helmchart app update
    • Recurrent state applying configuration channel?

    step 3: Multi-node cluster

    Goal: Use SUC to update a multi-node cluster.

    • Create a multi-node cluster
    • Deploy application
      • call the helm update/install only on control plane?
    • Install App updates through helm update
    • Prepare a SUC for OS update (k3s also? How?)
      • https://github.com/rancher/system-upgrade-controller
      • https://documentation.suse.com/cloudnative/k3s/latest/en/upgrades/automated.html
      • Update/deploy the SUC?
      • Update/deploy the SUC CRD with the update procedure


    Uyuni read-only replica by cbosdonnat

    Description

    For now, there is no possible HA setup for Uyuni. The idea is to explore setting up a read-only shadow instance of an Uyuni and make it as useful as possible.

    Possible things to look at:

    • live sync of the database, probably using the WAL. Some of the tables may have to be skipped or some features disabled on the RO instance (taskomatic, PXT sessions…)
    • Can we use a load balancer that routes read-only queries to either instance and the other to the RW one? For example, packages or PXE data can be served by both, the API GET requests too. The rest would be RW.

    Goals

    • Prepare a document explaining how to do it.
    • PR with the needed code changes to support it


    Flaky Tests AI Finder for Uyuni and MLM Test Suites by oscar-barrios

    Description

    Our current Grafana dashboards provide a great overview of test suite health, including a panel for "Top failed tests." However, identifying which of these failures are due to legitimate bugs versus intermittent "flaky tests" is a manual, time-consuming process. These flaky tests erode trust in our test suites and slow down development.

    This project aims to build a simple but powerful Python script that automates flaky test detection. The script will directly query our Prometheus instance for the historical data of each failed test, using the jenkins_build_test_case_failure_age metric. It will then format this data and send it to the Gemini API with a carefully crafted prompt, asking it to identify which tests show a flaky pattern.

    The final output will be a clean JSON list of the most probable flaky tests, which can then be used to populate a new "Top Flaky Tests" panel in our existing Grafana test suite dashboard.

    Goals

    By the end of Hack Week, we aim to have a single, working Python script that:

    1. Connects to Prometheus and executes a query to fetch detailed test failure history.
    2. Processes the raw data into a format suitable for the Gemini API.
    3. Successfully calls the Gemini API with the data and a clear prompt.
    4. Parses the AI's response to extract a simple list of flaky tests.
    5. Saves the list to a JSON file that can be displayed in Grafana.
    6. New panel in our Dashboard listing the Flaky tests

    Uyuni Health-check Grafana AI Troubleshooter by ygutierrez

    Description

    This project explores the feasibility of using the open-source Grafana LLM plugin to enhance the Uyuni Health-check tool with LLM capabilities. The idea is to integrate a chat-based "AI Troubleshooter" directly into existing dashboards, allowing users to ask natural-language questions about errors, anomalies, or performance issues.

    Goals

    • Investigate if and how the grafana-llm-app plug-in can be used within the Uyuni Health-check tool.
    • Investigate if this plug-in can be used to query LLMs for troubleshooting scenarios.
    • Evaluate support for local LLMs and external APIs through the plugin.
    • Evaluate if and how the Uyuni MCP server could be integrated as another source of information.
