There are various email synchronization programs like offlineimap or mbsync, which have some inherent limitations:
- mbsync does not support IMAP IDLE
- offlineimap does not yet support Python 3, proper IDLE and threading support would need a complete rewrite
Features
- support only IMAP, no POP3
- IMAP IDLE support is a must, especially:
- reconnection of dropped IDLE connections
- support IDLE for all IMAP folders
- be able to synchronize IMAP <-> Maildir at first, IMAP <-> IMAP would be nice to have
- bullet-proof cryptography, especially with respect to certificate validation and resistance to downgrade attacks (preferably make the TLS version configurable)
- use inotify API to support immediate synchronization back to the server if a message changes locally
- as simple configuration as possible with good defaults
nice to have:
- incorporate an API for external tagging tools like notmuch to synchronize tags if the remote supports it
- GMail support
Implementation
Preferably in Rust, using the imap crate as the core.
Scope
Try to create a MVP, especially flesh out proper testing and learn enough about the problem.

Mail client with mailing list workflow support in Rust by acervesato
Description
To create a mail user interface using Rust programming language, supporting mailing list patches workflow. I know, aerc is already there, but I would like to create something simpler, without integrated protocols. Just a plain user interface that is using some crates to read and create emails which are fetched and sent via external tools.
I already know Rust, but not the async support, which is needed in this case in order to handle events inside the mail folder and to send notifications.
Goals
- simple user interface in the style of
aerc, with some vim keybindings for motions and search - automatic run of external tools (like
mbsync) for checking emails - automatic run commands for notifications
- apply patch set from ML
- tree-sitter support with styles

Looking at Rust if it could be an interesting programming language by jsmeix
Get some basic understanding of Rust security related features from a general point of view.
This Hack Week project is not to learn Rust to become a Rust programmer. This might happen later but it is not the goal of this Hack Week project.
The goal of this Hack Week project is to evaluate if Rust could be an interesting programming language.
An interesting programming language must make it easier to write code that is correct and stays correct when over time others maintain and enhance it than the opposite.
Exploring Rust's potential: from basics to security by sferracci
Description
This project aims to conduct a focused investigation and practical application of the Rust programming language, with a specific emphasis on its security model. A key component will be identifying and understanding the most common vulnerabilities that can be found in Rust code.
Goals
Achieve a beginner/intermediate level of proficiency in writing Rust code. This will be measured by trying to solve LeetCode problems focusing on common data structures and algorithms. Study Rust vulnerabilities and learning best practices to avoid them.

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:
- Analyze & Identify: Dive into the
SUSE/rmtRuby codebase to identify and map out the exact critical path for server registration (e.g., controllers, services, database interactions). - Develop in Rust: Implement a functionally equivalent version of this registration logic in Rust.
- 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-sysormagnus. - 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. - 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.
