![]() ![]() If your code attempts to match a possibly inefficient Regexp against an untrusted input, an attacker may exploit it for efficient Denial of Service (so-called Regular expression DoS, or ReDoS). It is known that Regexp matching may take unexpectedly long. The default -yjit-call-threshold is changed to 30.The default -yjit-exec-mem-size is changed to 64 (MiB).Take advantage of finer-grained constant invalidation to invalidate less code when defining new constants.YJIT is now optimized to take advantage of object shapes. ![]() Simply run ruby with -yjit-stats to compute and dump stats (incurs some run-time overhead).Most of the statistics produced by RubyVM::ntime_stats are now available in release builds.RubyVM::ntime_stats returns Code GC metrics in addition toĮxisting inline_code_size and outlined_code_size keys:Ĭode_gc_count, live_page_count, freed_page_count, and freed_code_size.Introduce Code GC that frees all code pages when the memory consumptionīy JIT code reaches -yjit-exec-mem-size.Memory pages until actually utilized by JIT code. The RSS of a Ruby process is minimized because virtual memory pagesĪllocated by -yjit-exec-mem-size will not be mapped to physical Physical memory for JIT code is lazily allocated.Overall YJIT is 41% faster (geometric mean) than the Ruby interpreter on yjit-bench.The YJIT 3.2 release is faster than 3.1, and has about 1/3 as much memory overhead.Please reach out to the YJIT team should you run into any issues.In order to ensure that CRuby is built with YJIT, please install rustc >= 1.58.0.Building YJIT now requires Rust 1.58.0+.This release brings support for Apple M1/M2, AWS Graviton, Raspberry Pi 4 and more.YJIT now supports both x86-64 and arm64/aarch64 CPUs on Linux, MacOS, BSD and other UNIX platforms.Has been tested on production workloads for over a year and proven to be quite stable.An Update on WebAssembly/WASI Support in Ruby.Add WASI based WebAssembly support #5407.This makes distribution of Ruby apps a bit easier. In addition, we built a VFS on top of WASI so that we can easily pack Ruby apps into a single. So CRuby fills the gap by using Asyncify, which is a binary transformation technique to control execution in userland. Today’s WASI and WebAssembly itself is missing some features to implement Fiber, exception, and GC because it’s still evolving, and also for security reasons. Now you can try original CRuby in your web browser. An example use case is TryRuby playground’s CRuby support. This support encourages developers to utilize CRuby in a WebAssembly environment. It enables Ruby developers to write applications which run on such promised platforms. WebAssembly/WASI support in Ruby intends to leverage those projects. Though such applications need to communicate with operating systems, WebAssembly runs on a virtual machine which didn’t have a system interface. WASI (The WebAssembly System Interface) is designed for such use cases. But its objective - running programs efficiently with security on various environment - is long wanted not only for web but also by general applications. WebAssembly (Wasm) was originally introduced to run programs safely and fast in web browsers. Currently this port passes basic and bootstrap test suites not using the Thread API. This enables a CRuby binary to be available on a Web browser, a Serverless Edge environment, or other kinds of WebAssembly/WASI embedders. This is an initial port of WASI based WebAssembly support. Ruby 3.2 adds many features and performance improvements. We are pleased to announce the release of Ruby 3.2.0. ![]()
