TruffleRuby is a high-performance implementation of the Ruby programming language.
TruffleRuby aims to be fully compatible with the standard implementation of Ruby, MRI.
The Ruby language support can be added to GraalVM using the gu utility.
More information is available on the GraalVM website: https://www.graalvm.org/ruby/

Changelog

21.1.0

New features:

  • Access to local variables of the interactive Binding via language bindings is now supported: context.getBindings("ruby").putMember("my_var", 42); (#2030).
  • VALUEs in C extensions now expose the Ruby object when viewed in the debugger, as long as they have not been converted to native values.
  • Signal handlers can now be run without triggering multi-threading.
  • Fibers no longer trigger Truffle multi-threading.

Bug fixes:

  • Range#to_a wasn't working for long ranges (#2198, @tomstuart and @LillianZ).
  • Show the interleaved host and guest stacktrace for host exceptions (#2226).
  • Fix the label of the first location reported by Thread#backtrace_locations (#2229).
  • Fix Thread.handle_interrupt to defer non-pure interrupts until the end of the handle_interrupt block (#2219).
  • Clear and restore errinfo on entry and normal return from methods in C extensions (#2227).
  • Fix extra whitespace in squiggly heredoc with escaped newline (#2238, @wildmaples and @norswap).
  • Fix handling of signals with --single-threaded (#2265).
  • Fix Enumerator::Lazy#{chunk_while, slice_before, slice_after, slice_when} to return instances of Enumerator::Lazy (#2273).
  • Fix Truffle::Interop.source_location to return unavailable source sections for modules instead of null (#2257).
  • Fix usage of Thread.handle_interrupt in MonitorMixin#mon_synchronize.
  • Fixed TruffleRuby.synchronized to handle guest safepoints (#2277).
  • Fix control flow bug when assigning constants using ||= (#1489).
  • Fix Kernel#raise argument handling for hashes (#2298).
  • Set errinfo when rb_protect captures a Ruby exception (#2245).
  • Fixed handling of multiple optional arguments and keywords when passed a positional Hash (#2302).

Compatibility:

  • Prepend the GraalVM LLVM Toolchain to PATH when installing gems (#1974, #1088, #1343, #1400, #1947, #1931, #1588).
  • Installing the nokogiri gem now defaults to use the vendored libxml2 and libxslt, similar to CRuby, which means the corresponding system packages are no longer needed (#62).
  • Implemented $LOAD_PATH.resolve_feature_path.
  • Add Pathname#/ alias to Pathname#+ (#2178).
  • Fixed issue with large Integers in Math.log (#2184).
  • Updated Regexp.last_match to support Symbol and String parameter (#2179).
  • Added support for numbered block parameters (_1 etc).
  • Fixed String#upto issue with non-ascii strings (#2183).
  • Implemented partial support for pattern matching (#2186).
  • Make File.extname return '.' if the path ends with one (#2192, @tomstuart).
  • Include fractional seconds in Time#inspect output (#2194, @tomstuart).
  • Add support for Integer#[Range] and Integer#[start, length] (#2182, @gogainda).
  • Allow private calls with self as an explicit receiver (#2196, @wildmaples).
  • Fixed :perm parameter for File.write.
  • Implemented Time#floor and #ceil (#2201, @wildmaples).
  • Allow Range#include? and #member? with Time (#2202, @wildmaples).
  • Implemented Comparable#clamp(Range) (#2200, @wildmaples).
  • Added a Array#minmax to override Enumerable#minmax (#2199, @wildmaples).
  • Implemented chomp parameter for IO.{readlines, foreach} (#2205).
  • Implemented the Debug Inspector C API.
  • Added beginless range support for Range#{new, bsearch, count, each, equal_value, first, inspect, max, min, size, cover?, include?, ===}.
  • Added beginless range support for Array#{[], []=, slice, slice!, to_a, fill, values_at} (#2155, @LillianZ).
  • Added beginless range support for String#{byteslice, slice, slice!} and Symbol#slice (#2211, @LillianZ).
  • Added beginless range support for Kernel#{caller, caller_locations} and Thread#backtrace_locations (#2211, @LillianZ).
  • Make rand work with exclusive range with Float (#1506, @gogainda)
  • Fixed String#dump's formatting of escaped unicode characters (#2217, @meganniu).
  • Switched to the io-console C extension from C ruby for better performance and compatibility in irb.
  • Coerce the message to a String for BasicSocket#send (#2209, @HoneyryderChuck).
  • Support buffer argument for UDPSocket#recvfrom_nonblock (#2209, @HoneyryderChuck).
  • Fixed Integer#digits implementation to handle more bases (#2224, #2225).
  • Support the inherit parameter for Module#{private, protected, public}_method_defined?.
  • Implement Thread.pending_interrupt? and Thread#pending_interrupt? (#2219).
  • Implement rb_lastline_set (#2170).
  • Implemented Module#const_source_location (#2212, @tomstuart and @wildmaples).
  • Do not call File.exist? in Dir.glob as File.exist? is often mocked (#2236, @gogainda).
  • Coerce the inherit argument to a boolean in Module#const_defined? and Module#const_get (#2240).
  • Refinements take place at Object#method and Module#instance_method (#2004, @ssnickolay).
  • Add support for rb_scan_args_kw in C API (#2244, @LillianZ).
  • Update random implementation layout to be more compatible (#2234).
  • Set RbConfig::CONFIG['LIBPATHFLAG'/'RPATHFLAG'] like MRI to let $LIBPATH changes in extconf.rb work.
  • Access to path and mode via rb_io_t from C has been changed to improve compatibility for io-console.
  • Implemented the Time.at in: parameter.
  • Implemented Kernel#raise cause parameter.
  • Improved compatibility of Signal.trap and Kernel#trap (#2287, @chrisseaton).
  • Implemented GC.stat(:total_allocated_objects) as 0 (#2292, @chrisseaton).
  • ObjectSpace::WeakMap now supports immediate and frozen values as both keys and values (#2267).
  • Call divmod when coercion to Float fails for #sleep (#2289, @LillianZ).

Performance:

  • Multi-Tier compilation is now enabled by default, which improves warmup significantly.
  • Improve the performance of checks for recursion (#2189, @LillianZ).
  • Improve random number generation performance by avoiding synchronization (#2190, @ivoanjo).
  • We now create a single call target per block by default instead of two.
  • Some uses of class variables are now much better optimized (#2259, @chrisseaton).
  • Several methods that need the caller frame are now always inlined in their caller, which speeds up the interpreter and reduces footprint.
  • Pasting code in IRB should be reasonably fast, by updating to irb 1.3.3 and reline 0.2.3 (#2233).

Changes:

  • Standalone builds of TruffleRuby are now based on JDK11 (they used JDK8 previously). There should be no user-visible changes. Similarly, JDK11 is now used by default in development instead of JDK8.
  • The deprecated Truffle::System.synchronized has been removed.
  • Java.synchronized has been removed, it did not work on host objects.
