News

We are pleased to announce the release of Ruby 3.3.0-preview3. Ruby 3.3 adds a new parser named Prism, uses Lrama as a parser generator, adds a new pure-Ruby JIT compiler named RJIT, and many performance improvements especially YJIT.

Prism

• Introduced the Prism parser as a default gem
  • Prism is a portable, error tolerant, and maintainable recursive descent parser for the Ruby language
• Prism is production ready and actively maintained, you can use it in place of Ripper
  • There is extensive documentation on how to use Prism
  • Prism is both a C library that will be used internally by CRuby and a Ruby gem that can be used by any tooling which needs to parse Ruby code
  • Notable methods in the Prism API are:
    • Prism.parse(source) which returns the AST as part of a ParseResult
    • Prism.dump(source, filepath) which returns the serialized AST as a String
    • Prism.parse_comments(source) which returns the comments
• You can make pull requests or issues directly on the Prism repository if you are interested in contributing

Use Lrama instead of Bison

• Replace Bison with Lrama LALR parser generator Feature #19637
  • If you have interest, please see The future vision of Ruby Parser
  • Lrama internal parser is replaced with LR parser generated by Racc for maintainability
  • Parameterizing Rules (?, *, +) are supported, it will be used in Ruby parse.y

RJIT

• Introduced a pure-Ruby JIT compiler RJIT and replaced MJIT.
  • RJIT supports only x86-64 architecture on Unix platforms.
  • Unlike MJIT, it doesn’t require a C compiler at runtime.
• RJIT exists only for experimental purposes.
  • You should keep using YJIT in production.
• If you are interested in developing JIT for Ruby, please check out k0kubun’s presentation on Day 3 of RubyKaigi.

YJIT

• Major performance improvements over 3.2
  • Support for splat and rest arguments has been improved.
  • Registers are allocated for stack operations of the virtual machine.
  • More calls with optional arguments are compiled.
  • Exception handlers are also compiled.
  • Instance variables no longer exit to the interpreter
    with megamorphic object shapes.
  • Unsupported call types no longer exit to the interpreter.
  • Integer#!=, String#!=, Kernel#block_given?, Kernel#is_a?,
    Kernel#instance_of?, Module#=== are specially optimized.
  • Now more than 3x faster than the interpreter on optcarrot!
• Significantly improved memory usage over 3.2
  • Metadata for compiled code uses a lot less memory.
  • Generate more compact code on ARM64
• Compilation speed is now slightly faster than 3.2.
• Add RubyVM::YJIT.enable that can enable YJIT at run-time
  • You can start YJIT without modifying command-line arguments or environment variables.
  • This can also be used to enable YJIT only once your application is
    done booting. --yjit-disable can be used if you want to use other
    YJIT options while disabling YJIT at boot.
• Option to disable code GC and treat --yjit-exec-mem-size as a hard limit
  • Can produce better copy-on-write behavior on servers using unicorn and forking
• ratio_in_yjit stat produced by --yjit-stats is now avaiable in release builds,
  a special stats or dev build is no longer required to access most stats.
• Exit tracing option now supports sampling
  • --trace-exits-sample-rate=N
• --yjit-perf is added to facilitate profiling with Linux perf.
• More thorough testing and multiple bug fixes

M:N thread scheduler

• M:N thread scheduler was introduced. [Feature #19842]
  • M Ruby threads are managed by N native threads (OS threads) so the thread creation and management cost are reduced.
  • It can break C-extension compatibility so that M:N thread scheduler is disabled on the main Ractor by default.
    • RUBY_MN_THREADS=1 environment variable enables M:N threads on the main Ractor.
    • M:N threads are enabled on non-main Ractors.
  • RUBY_MAX_CPU=n environment variable sets maximum number of N (maximum number of native threads). The default value is 8.
    • Since only one Ruby thread per Ractor can run at the same time, the number of native threads will be used, which is the smaller of the number specified in RUBY_MAX_CPU and the number of running Ractors. So that single Ractor applications (most of applications) will use 1 native thread.
    • To support blocking operations, more than N native threads can be used.

Other Notable New Features

Language

Performance improvements

• defined?(@ivar) is optimized with Object Shapes.
• Name resolution such as Socket.getaddrinfo can now be interrupted (in environments where pthreads are available). Feature #19965
  • For this purpose, a pthread is now created whenever calling getaddrinfo or getnameinfo. This incurs some overhead in name resolution (about 2.5x in our experiments). We do not expect the name resolution overhead to be a problem for most applications, but if you observe such, or if you see unexpected affects that you believe are due to this change, please report them.
• Environment variable RUBY_GC_HEAP_REMEMBERED_WB_UNPROTECTED_OBJECTS_LIMIT_RATIO has been added. Feature #19571
• Children of old objects are no longer immedately promoted to the old generation in the garbage collector. Feature #19678
• Support for weak references has been added to the garbage collector. Feature #19783

Other notable changes since 3.2

IRB

IRB has received several enhancements, including but not limited to:

• Advanced irb:rdbg integration that provides an equivalent debugging experience to pry-byebug (doc).
• Pager support for ls, show_source and show_cmds commands.
• More accurate and helpful information provided by the ls and show_source commands.
• Experimental autocompletion using type analysis (doc).
• It is now possible to change the font color and font style in the completion dialog by a newly introduced class Reline::Face (doc)

In addition, IRB has also undergone extensive refactoring and received dozens of bug fixes to facilitate easier future enhancements.

I wrapped my head around instance_eval recently, so I wrote up a short article illustrating how it’s used in Rails’ route config.

Guinevere Piazera Larsen sent us the CfP for the upcoming Debuggers and Analysis Tools at FOSDEM 2024!:

We are excited to announce that the call for proposals is now open for the Debuggers and Analysis Tools developer room at the upcoming FOSDEM 2024, to be hosted on Saturday, February 3rd 2024 in Brussels, Belgium.

This devroom is a collaborative effort and is organized by dedicated people from projects such as GDB, SystemTap, Valgrind, GNU poke, Elfutils, binutils, Libabigail, and the like.

Important Dates:

   1st December 2023    Submission deadline

   8th December 2023    Acceptance notifications

   15th December 2023   Final Schedule announcement

   3rd February 2024    Conference dates

## CFP Introduction

This devroom is geared towards authors, users and enthusiasts of Free Software programs involved with debugging and analyzing ELF programs using all the binary information available (including DWARF data).

The goal of the devroom is for developers to get in touch with each other and with users of their tools, have interesting and hopefully productive discussions, and finally what is most important: to have fun.

The format of the expected presentations will cover a range that

includes:

    * Talks oriented towards developers of these projects

    * Presentation / Introductory Workshops for users of these programs

    * Activities oriented towards collaboration & standardization between these programs

All presentation slots are 25 minutes, with 15 minutes recommended for presentations, and 10 minutes for Q&A. This way we can have 8 slots and bio breaks, covering many topics!

### What is FOSDEM?

*FOSDEM is a free event for software developers to meet, share ideas and collaborate.*

Every year, thousands of developers of free and open source software from all over the world gather at the event in Brussels.

FOSDEM 2024 will take place on Saturday 3 and Sunday 4 February 2024.

It will be an in-person event at the *ULB Solbosch Campus, Brussels, Belgium, Europe.* If you aren’t there, you can watch the live streams from the main tracks and developer rooms.

### Important stuff:

– FOSDEM is free to attend. There is no registration.

– [FOSDEM website](https://fosdem.org/)

– [FOSDEM code of conduct](https://fosdem.org/2024/practical/conduct/)

– [FOSDEM Schedule](https://fosdem.org/2024/schedule/)

### Desirable topics:

In this devroom, we’re interested in any projects that directly reads binary files and analyses or manipulates them directly. Some projects and tools that fit the devroom are:

– GDB

– LLDB

– Ghidra

– Valgrind

– Dyninst

– GNU poke

– Binutils

– SystemTap

– Elfutils

– Libabigail

– Radare2

And any other debugging or binary analysis tool or framework

projects that might be of interest to Free Software enthusiasts.

### Topic overlap

There are over 50 developer rooms this year, and multiple main tracks, so there may be overlap with some other events.

If the topic would fit more than one devroom, you are free to choose which to submit to, but we encourage you to consider the focus of the talk, and see which devroom is best matched.

The year was 1983. Microsoft was slowly becoming a well-known tech company in the PC space. Two years before, in 1981, Its MS-DOS operating system would be installed in the first IBM PC. It launched its first-word processing program, Word, earlier in 1983, along with its first Microsoft Mouse product. It even made Mac and PC hardware expansion cards. However, 40 years ago today, on November 10, 1983 at a press event in New York City, Microsoft first revealed its plans to launch an all-new graphical user interface-based PC operating system. The company called the OS Windows. If you’ve ever used Windows 1.0 – either because you’re old and remember it as new, or in a VM – you’ll know just how limited and useless Windows 1.0 really was. Still, it set the stage for one of the most successful tech products of all time, and few products in tech can boast about being on the market for four decades. That being said, I’m not exactly sad Windows seems to be in its twilight years.
