TruffleRuby - GraalVM Community Edition 19.3.0

Ruby is an experimental language in the GraalVM 19.3.0 release. More information is available on the GraalVM website. Changes in 19.3.0 (from the project changelog):

New features:

• Compilation of C extensions is now done with an internal LLVM toolchain producing both native code and bitcode. This means more C extensions should compile out of the box and this should resolve most linker-related issues.
• It is no longer necessary to install LLVM for installing C extensions on TruffleRuby.
• It is no longer necessary to install libc++ and libc++abi for installing C++ extensions on TruffleRuby.
• On macOS, it is no longer necessary to install the system headers package (#1417).
• License updated to EPL 2.0/GPL 2.0/LGPL 2.1 like recent JRuby.

Bug fixes:

• rb_undef_method now works for private methods (#1731, @cky).
• Fixed several issues when requiring C extensions concurrently (#1565, @eregon).
• self.method ||= value with a private method now works correctly (#1673, @pitr-ch).
• Fixed RegexpError: invalid multibyte escape for binary regexps with a non-binary String (#1433, @aardvark179).
• Arrays now report their methods to other languages for interopability (#1768).
• Installing sassc now works due to using the LLVM toolchain (#1753).
• Renamed Truffle::Interop.respond_to? to avoid conflict with Ruby's respond_to? (#1491).
• Warn only if $VERBOSE is true when a magic comment is ignored (#1757, @nirvdrum).
• Make C extensions use the same libssl as the one used for the openssl C extension (#1770).

Compatibility:

• GC.stat can now take an optional argument (#1716, @kirs).
• Kernel#load with wrap has been implemented (#1739, @chrisseaton).
• Implemented Kernel#spawn with :chdir (#1492).
• Implemented rb_str_drop_bytes, notably used by OpenSSL (#1740, @cky).
• Include executables of default gems, needed for rails new in Rails 6.
• Use compilation flags similar to MRI for C extension compilation.
• Warn for gem update --system as it is not fully supported yet and is often not needed.
• Pass -undefined dynamic_lookup to the linker on macOS like MRI.

Performance:

• Core methods are no longer always cloned, which reduces memory footprint and should improve warmup.
• Inline cache calls to rb_intern() with a constant name in C extensions.
• Improve allocation speed of native handles for C extensions.
• Improve the performance of NIL_P and INT2FIX in C extensions.
• Various fixes to improve Rack performance.
• Optimize String#gsub(String) by not creating a Regexp and using String#index instead.
• Fixed "FrameWithoutBoxing should not be materialized" compilation issue in TryNode.

TruffleRuby - GraalVM Community Edition 19.2.0

New features:

Changes:

• An interop read message sent to a Proc will no longer call the Proc.

Performance:

• Several String methods have been made faster by the usage of vector instructions
  when searching for a single-byte character in a String.
• Methods needing the caller frame are now better optimized.

TruffleRuby - GraalVM Community Edition 19.2.0-dev-b01

This is a preview release for 19.2 and we recommend testing it for all users.

TruffleRuby - GraalVM Community Edition 19.1.1

Ruby is an experimental language in the GraalVM 19.1.1 release. More information is available on the GraalVM website. Changes in 19.1.1:

• Updated to use GraalVM 19.1.1 release.

TruffleRuby - GraalVM Community Edition 19.1.0

Ruby is an experimental language in the GraalVM 19.1.0 release.

More information is available on the GraalVM website: http://www.graalvm.org/docs/reference-manual/languages/ruby/

Changes in 19.1.0:

Bug fixes:

• Sharing for thread-safety of objects is now triggered later as intended, e.g., when a second Thread is started.
• Fixed Array#to_h so it doesn't set a default value (#1698).
• Removed extra public methods on IO (#1702).
• Fixed Process.kill(signal, Process.pid) when the signal is trapped as :IGNORE (#1702).
• Fixed Addrinfo.new(String) to reliably find the address family (#1702).
• Fixed argument checks in BasicSocket#setsockopt (#1460).
• Fixed ObjectSpace.trace_object_allocations (#1456).
• Fixed BigDecimal#{clone,dup} so it now just returns the receiver, per Ruby 2.5+ semantics (#1680).
• Fixed creating BigDecimal instances from non-finite Float values (#1685).
• Fixed BigDecimal#inspect output for non-finite values (e.g, NaN or -Infinity) (#1683).
• Fixed BigDecimal#hash to return the same value for two BigDecimal objects that are equal (#1656).
• Added missing BigDecimal constant definitions (#1684).
• Implemented rb_eval_string_protect.
• Fixed rb_get_kwargs to correctly handle optional and rest arguments.
• Calling Kernel#raise with a raised exception will no longer set the cause of the exception to itself (#1682).
• Return a FFI::Function correctly for functions returning a callback.
• Convert to intuitive Ruby exceptions when INVOKE fails (#1690).
• Implemented FFI::Pointer#clear (#1687).
• Procs will now yield to the block in their declaration context even when called with a block argument (#1657).
• Fixed problems with calling POSIX methods if Symbol#[] is redefined (#1665).
• Fixed sharing of Array and Hash elements for thread-safety of objects (#1601).
• Fixed concurrent modifications of Gem::Specification::LOAD_CACHE (#1601).
• Fix TCPServer#accept to set #do_not_reverse_lookup correctly on the created TCPSocket.

Compatibility:

• Exceptions from coerce are no longer rescued, like MRI.
• Implemented Integer#{allbits?,anybits?,nobits?}.
• Integer#{ceil,floor,truncate} now accept a precision and Integer#round accepts a rounding mode.
• Added missing Enumerable#filter and Enumerator::Lazy#filter aliases to the respective select method (#1610).
• Implemented more Ripper methods as no-ops (#1694).
• Implemented rb_enc_sprintf (#1702).
• Implemented ENV#{filter,filter!} aliases for select and select!.
• Non-blocking StringIO and Socket APIs now support exception: false like MRI (#1702).
• Increased compatibility of BigDecimal.
• String#-@ now performs string deduplication (#1608).
• Hash#merge now preserves the key order from the original hash for merged values (#1650).
• Coerce values given to FFI::Pointer methods.
• FrozenError is now defined and is used for can't modify frozen object exceptions.
• StringIO is now available by default like in MRI, because it is required by RubyGems.

Changes:

• Interactive sources (like the GraalVM polyglot shell) now all share the same binding (#1695).
• Hash code calculation has been improved to reduce hash collisions for Hash and other cases.

Performance:

• eval(code, binding) for a fixed code containing blocks is now much faster. This improves the performance of rendering ERB templates containing loops.
• rb_str_cat has been changed to improve performance. THe C string is now concatentated without first being converted to a Ruby string or having its encoding checked. As a side effect the behaviour of rb_str_cat should now more closely match that of MRI.
