Many new features and >> improvements are included for the increasingly diverse and expanding >> demands for Ruby. With this major update from Ruby 2.5 in Fedora 29 to >> Ruby 2.6 in Fedora 30, Fedora becomes the superior Ruby development >> platform. >> >> == Owner == >> * Name: [[User:vondruch| Vít Ondruch]], [[User:pvalena| Pavel Valena]] >> * Email: vondruch@xxxxxxxxxx, pvalena@xxxxxxxxxx >> >> == Detailed Description == >> Ruby 2.6 is upstream's new major release of Ruby. Many new features >> and improvements are included. >> >> === JIT === >> >> Ruby 2.6 introduces an initial implementation of JIT (Just-in-time) compiler. >> >> JIT compiler aims to improve performance of any Ruby program >> execution. Unlike ordinary JIT compilers for other languages, Ruby’s >> JIT compiler does JIT compilation in a unique way, which prints C code >> to a disk and spawns common C compiler process to generate native >> code. >> >> The main purpose of this JIT release is to provide a chance to check >> if it works for your platform and to find out security risks before >> the 2.6 release. JIT compiler is supported when Ruby is built by GCC, >> Clang, or Microsoft VC++, which needs to be available on runtime. >> Otherwise you can’t use it for now. >> >> As of Ruby 2.6.0 preview3, we achieved 1.7x faster performance than >> Ruby 2.5 on CPU-intensive non-trivial benchmark workload called >> Optcarrot. The performance on memory-intensive workload like Rails >> application are going to be improved as well. >> >> === RubyVM::AST [Experimental] === >> >> Ruby 2.6 introduces `RubyVM::AST` module. >> >> This module has `parse` method which parses a given ruby code of >> string and returns AST (Abstract Syntax Tree) nodes, and `parse_file` >> method which parses a given ruby code file and returns AST nodes. >> `RubyVM::AST::Node` class is also introduced. You can get location >> information and children nodes from `Node` objects. This feature is >> experimental. Compatibility of the structure of AST nodes are not >> guaranteed. >> >> === New Features === >> >> * Add a new alias `then` to `Kernel#yield_self`. >> * Add `Random.bytes`. >> * Add `Binding#source_location`. This method returns the source >> location of binding, a 2-element array of __FILE__ and __LINE__. >> * Add `:exception` option to let `Kernel.#system` raise error instead >> of returning `false`. >> * Add a new alias then to `Kernel#yield_self`. >> * `else` without `rescue` now causes a syntax error. [EXPERIMENTAL] >> * Constant names may start with a non-ASCII capital letter. >> * An endless range, (1..), is introduced. It works as it has no end. >> >> === Performance improvements === >> >> * Speedup `Proc#call` because we don’t need to care about $SAFE any >> more. With `lc_fizzbuzz` benchmark it makes x1.4 speed improvement. >> * Speedup `block.call` where block is passed block parameter. Ruby 2.6 >> improves the performance of passed block calling. There can observed >> 2.6x improvement with micro-benchmarks. >> * Transient Heap (theap) is introduced. theap is managed heap for >> short-living memory objects which are pointed by specific classes. For >> example, making small and short-living Hash object is x2 faster. With >> rdoc benchmark, 6-7% performance improvement is observed. >> >> === Other notable changes since 2.5 === >> >> * `$SAFE` is a process global state and we can set `0` again. >> * Passing `safe_level` to `ERB.new` is deprecated. `trim_mode` and >> `eoutvar` arguments are changed to keyword arguments. >> * Merged RubyGems 3.0.0.beta2. >> * Merge Bundler as default gem. >> >> == Benefit to Fedora == >> >> With a latest release, Ruby language is supporting the newest language >> features, which enables even faster and easier development of Ruby >> applications. >> >> == Scope == >> * Proposal owners: >> ** Finish packaging of Ruby 2.6.
