TruffleRuby - GraalVM Community Edition 1.0 RC5

TruffleRuby is high performance implementation of the Ruby programming language, compatible with MRI 2.4.4.

TruffleRuby is progressing fast but is currently probably not ready for you to try running your full Ruby application on. However it is ready for experimentation and curious end-users to try on their gems and smaller applications.

TruffleRuby runs Rails, and passes the majority of the Rails test suite. But it is missing support for Nokogiri and ActiveRecord database drivers which makes it not practical to run real Rails applications at the moment.

The Ruby language components can be installed in GraalVM using the gu utility.

Release Notes

New features:

• It is no longer needed to add LLVM (/usr/local/opt/llvm@4/bin) to PATH on macOS.
• Improve error message when LLVM, clang or opt is missing.
• Automatically find LLVM and libssl with MacPorts on macOS (#1386).
• --log.ruby.level= can be used to set the log level from any launcher.
• Add documentation about installing with Ruby managers/installers and how to
  run TruffleRuby in CI such as TravisCI (#1062, #1070).
• String#unpack1 has been implemented.

Bug fixes:

• Allow any name for constants with rb_const_get()/rb_const_set() (#1380).
• Fix defined? with an autoload constant to not raise but return nil if the autoload fails (#1377).
• Binary Ruby Strings can now only be converted to Java Strings if they only
  contain US-ASCII characters. Otherwise, they would produce garbled Java Strings (#1376).
• #autoload now correctly calls main.require(path) dynamically.
• Hide internal file from user-level backtraces (#1375).
• Show caller information in warnings from the core library (#1375).
• #require and #require_relative should keep symlinks in $" and __FILE__ (#1383).
• Random seeds now always come directly from /dev/urandom for MRI compatibility.
• SIGINFO, SIGEMT and SIGPWR are now defined (#1382).
• Optional and operator assignment expressions now return the value
  assigned, not the value returned by an assignment method (#1391).
• WeakRef.new will now return the correct type of object, even if WeakRef is subclassed (#1391).
• Resolving constants in prepended modules failed, this has now been fixed (#1391).
• Send and Symbol#to_proc now take account of refinements at their call sites (#1391).
• Better warning when the timezone cannot be found on WSL (#1393).
• Allow special encoding names in String#force_encoding and raise an exception on bad encoding names (#1397).
• Fix Socket.getifaddrs which would wrongly return an empty array (#1375).
• Binding now remembers the file and line at which it was created for #eval.
  This is notably used by pry's binding.pry.
• Resolve symlinks in GEM_HOME and GEM_PATH to avoid related problems (#1383).
• Refactor and fix #autoload so other threads see the constant defined while
  the autoload is in progress (#1332).
• Strings backed by NativeRopes now make a copy of the rope when duped.
• String#unpack now taints return strings if the format was tainted, and
  now does not taint the return array if the format was tainted.
• Lots of fixes to Array#pack and String#unpack tainting, and a better
  implementation of P and p.
• Array literals could evaluate an element twice under some circumstances.

Performance:

• Optimize required and optional keyword arguments.
• rb_enc_to_index is now faster by eliminating an expensive look-up.

Changes:

• -Xlog= now needs log level names to be upper case.
• -Dtruffleruby.log and TRUFFLERUBY_LOG have been removed -
  use -Dpolyglot.log.ruby.level.
• The log format, handlers, etc are now managed by the Truffle logging system.
• The custom log levels PERFORMANCE and PATCH have been removed.

TruffleRuby - GraalVM Community Edition 1.0 RC4

RC4 only updates the functionality of Graal JavaScript.
Therefore, RC4 does not update the functionality of the Ruby component compared to RC3.
Ruby users only need to update to RC4 if they want to use Ruby from GraalVM 1.0.0 RC4.

TruffleRuby - GraalVM Community Edition 1.0 RC3

TruffleRuby is high performance implementation of the Ruby programming language, compatible with MRI 2.4.4.

TruffleRuby is progressing fast but is currently probably not ready for you to try running your full Ruby application on. However it is ready for experimentation and curious end-users to try on their gems and smaller applications.

TruffleRuby runs Rails, and passes the majority of the Rails test suite. But it is missing support for Nokogiri and ActiveRecord database drivers which makes it not practical to run real Rails applications at the moment.

The Ruby language components can be installed in GraalVM using the gu utility.

Release Notes

• is_a? can be called on foreign objects.
• Qnil/Qtrue/Qfalse/Qundef can now be used as initial value for global variables in C extensions.
• SIGPIPE is correctly caught on SubstrateVM, and the corresponding write() raises Errno::EPIPE when the read end of a pipe or socket is closed (#1375).
• Use the magic encoding comment for determining the source encoding when using eval() (#1376).
• Faster stat()-related calls, by returning the relevant field directly and avoiding extra allocations.
• rb_str_new()/rb_str_new_cstr() are much faster by avoiding extra copying and allocations.
• String#{sub,sub!} are faster in the common case of an empty replacement string.
• Improved reading from IO with a delimiter (e.g., IO#each), improves e.g. iterating through lines in a File.
• Use the byte[] of the given Ruby String when calling eval() directly for parsing.
• More details in https://github.com/oracle/truffleruby/blob/master/CHANGELOG.md

Release Notes

• TruffleRuby is now compatible with Ruby 2.4.4.
• object.class on a Java Class object will give you an object on which you can call instance methods, rather than static methods which is what you get by default.
• Java.import name imports Java classes as top-level constants.
• Coercion of foreign numbers to Ruby numbers now works.
• to_s works on all foreign objects and calls the Java toString.
• to_str will try to UNBOX and then re-try to_str, in order to provoke the unboxing of foreign strings.
• More details in https://github.com/oracle/truffleruby/blob/master/CHANGELOG.md
