[tor-dev] Rust rewrite help

[Ivan Mandura]

Hello,

My name is Ivan and I would like to help out with Rust rewrite.

I'm a huge fan of both Rust and TOR. Recently, I spent some time in China
and it made me realize the importance of a project like TOR.

Have experience with low-level code, being in DB industry for a few years
now.

Any pointers would be of huge help :)

Thanks,
Ivan

Hi Ivan,

Here are our getting started documents:
https://gitweb.torproject.org/tor.git/tree/doc/HACKING/GettingStartedRust.md
https://gitweb.torproject.org/tor.git/tree/doc/HACKING/GettingStarted.md

Our goal is to gradually add interchangeable Rust crates to Tor,
so that they can be used as alternatives to the corresponding C code.

You might find torguts helpful to understand Tor's current structure:
https://gitweb.torproject.org/user/nickm/torguts.git/tree/

Other Core Tor developers know much more about Rust than I do.
They can tell you if there is anywhere we are focusing on right now.

You can start by building Tor with Rust, and making sure the unit tests pass.
We use "make check" to run a bunch of tests.

Will start reading docs. If somebody has something simple to start with
please send it my way.

If you want to modify existing code, this one looks easy:

Wrap types in protover.rs
https://trac.torproject.org/projects/tor/ticket/24030


If you like FFI from Rust to C, here are some options:

Wrap our sha2 interface in Rust which implements the appropriate traits
https://trac.torproject.org/projects/tor/ticket/24659

Wrap our PRNG interface(s) in Rust with appropriate traits
https://trac.torproject.org/projects/tor/ticket/24660


If you like testing, and FFI from C to Rust, and want to get involved
with our C-based unit tests - try these after your first patch?

Test all rust functions' behavior when called from C with bad UTF8
https://trac.torproject.org/projects/tor/ticket/24029

consdiff implementation in Rust
https://trac.torproject.org/projects/tor/ticket/24609
(Most people's repositories are on git.torproject.org.)


And here are all the Rust tickets:

https://trac.torproject.org/projects/tor/query?status=accepted&status=assigned&status=merge_ready&status=needs_information&status=needs_review&status=needs_revision&status=new&status=reopened&keywords=~rust&col=id&col=summary&col=status&col=type&col=priority&col=milestone&col=component&order=priority
