Misc #19475
Updated by k0kubun (Takashi Kokubun) about 1 year ago
I'd like to propose Matthew Valentine-House (@eightbitraptor) as a committer. He has been [an active contributor to Ruby](https://github.com/ruby/ruby/pulls?q=author%3Aeightbitraptor) in the following areas:
* **Variable Width Allocation** - He worked on the VWA (RVARGC) project to increase performance by improving the spatial locality of objects [https://bugs.ruby-lang.org/issues/17816](https://bugs.ruby-lang.org/issues/17816)
* **Compaction movement refactor** - He re-worked the GC's compaction algorithm to facilitate object movement between the size pools to ensure VWA uses memory efficiently: [https://bugs.ruby-lang.org/issues/18619](https://bugs.ruby-lang.org/issues/18619) (He spoke about this at [Ruby Kaigi 2022 in 津](https://rubykaigi.org/2022/presentations/eightbitraptor.html#day2))
* **LLDB refactor & Developer experience** - He is also passionate about the developer experience of working on the Ruby codebase. He has been refactoring the LLDB helpers to give them some more structure and make debugging Ruby easier: [https://github.com/ruby/ruby/pull/6129](https://github.com/ruby/ruby/pull/6129)
He's really passionate about making Ruby's GC better. He wants to implement novel GC algorithms and techniques in CRuby, and I want to make it easier for him to push changes required for it. In particular, he's been working on integrating the [MMTk project](https://www.mmtk.io/) into Ruby (They're producing nightly builds [here](https://github.com/shopify/ruby-mmtk-builder)).
This is a proposal from @tenderlovemaking and myself. If approved, we'll help him onboard as a Ruby committer. I already heard that @matz and @mame are in favor of the idea, but let me formally propose this here.
