TruffleRuby - GraalVM Community Edition 22.1.0

on GitHub

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 component can be added to GraalVM using the gu utility.
More information is available on the website: http://www.graalvm.org/ruby/

Compatibility:

• Implement Pathname#{empty?, glob} (#2559, @bjfish)
• Fixed Rational('') to raise error like MRI (#2566, @aardvark179).
• Freeze instances of Range but not subclasses, like CRuby (#2570, @MattAlp).

• Implement 'rb_str_buf_append' (@bjfish).
• Add patch for digest so that TruffleRuby implementation is not overridden (@bjfish).
• Handle encoding conversion errors when reading directory entries (@aardvark179).
• Follow symlinks when processing */ directory glob patterns. (#2589, @aardvark179).
• Set @gem_prelude_index variable on the default load paths (#2586 , @bjfish)
• Do not call IO#flush dynamically from IO#close (#2594, @gogainda).
• Implement rb_str_new_static for C extensions that use it (@aardvark179).
• Rewrote ArrayEachIteratorNode and re-introduced each specs for MRI parity when mutating arrays whilst iterating, rather than crashing (#2587, @MattAlp)
• Update String#rindex to only accept Regexp or objects convertable to String as the first parameter (#2608, @bjfish).
• Update String#<< to require one argument (#2609, @bjfish).
• Update String#split to raise TypeError when false is given (#2606, @bjfish).
• Update String#lstrip! to remove leading null characters (#2607, @bjfish).
• Update File.utime to return the number of file names in the arguments (#2616, @bjfish).
• Update Dir.foreach to accept an encoding parameter (#2627, @bjfish).
• Update IO.readlines to ignore negative limit parameters (#2625 , @bjfish).
• Update Math.sqrt to raise a Math::DomainError for negative numbers (#2621, @bjfish).
• Update Enumerable#inject to raise an ArgumentError if no block or symbol are given (#2626, @bjfish).
• Fix Marshal.dump to raise an error when an object has singleton methods (@bjfish).

Performance:

• Increase dispatch limit for string library to handle mutable, immutable and non-strings (@aardvark179)
• Switch to Arrays.mismatch() in string comparison for better performance (@aardvark179).
• Removed extra array allocations for method calls in the interpreter to improve warmup performance (@aardvark179).
• Optimize Dir[] by sorting entries as they are found and grouping syscalls (#2092, @aardvark179).
• Reduce memory footprint by tracking VALUEs created during C extension init separately (@aardvark179).
• Rewrote ArrayEachIteratorNode to optimize performance for a constant-sized array and reduce specializations to 1 general case (#2587, @MattAlp)
• Reduce conversion of VALUEs to native handle during common operations in C extensions (@aardvark179).
• Improved performance of regex boolean matches (e.g., Regexp#match?) by avoiding match data allocation in TRegex (#2588, @nirvdrum).
• Remove overhead when getting using RDATA_PTR (@aardvark179).
• Additional copy operations have been reduced when performing IO (#2536, @aardvark179).

Changes:

• Foreign exceptions are no longer translated to RuntimeError but instead remain as foreign exceptions, see the documentation for how to rescue them (@eregon).
