2024-09-25[ruby/prism] Type every node field and mark on-error-only types explicitlyBenoit Daloze

2024-05-13[ruby/prism] Autoload newlines and comment visitorsKevin Newton
Having the @newline instance variable in every node adds up, and since it is so rarely used, we only want to add it when necessary. Moving this into an autoloaded file and moving the instance variable out of the default initializers reduces allocated memory because the nodes are now smaller and some fit into the compact list. On my machine, I'm seeing about an 8% drop. https://github.com/ruby/prism/commit/eea92c07d2

2024-04-24[ruby/prism] Change inspect from recursive to a queueKevin Newton
We would previously cause a stack overflow if we parsed a file that was too deeply nested when we were calling inspect. Instead, we now use a queue of commands to do it linearly so we don't. https://github.com/ruby/prism/commit/0f21f5bfe1

2024-03-18[ruby/prism] Use `require_relative` in the Prism codebaseKoichi ITO
If there are many searches in the `$LOAD_PATH` in the user environment, require will perform unnecessary searches that are not needed. In contrast, `require_relative` is efficient because it uses a relative path. https://github.com/ruby/prism/commit/438ccc67bd

2024-03-04[ruby/prism] Use a more efficient StringIO on TruffleRubyBenoit Daloze
* The stdlib StringIO is synchronized and this occurs a high overhead. * This is about twice as fast on TruffleRuby but surprisingly it is slower on JRuby. I am not sure why but probably @ivar access and integer arithmetic is much slower than Java field access/arithmetic on JRuby. * On CRuby interpreter it is slower, which is expected as the GVL already protects StringIO. * So we enable this only on TruffleRuby to not slow down other Rubies. * PRISM_FFI_BACKEND=true ruby -v -Ilib -rprism -rbenchmark -e '300.times { p Benchmark.realtime { Dir.glob("lib/**/*.rb") { |f| Prism.parse_file(f) } } }' ruby 3.3.0: 0.215 => 0.251 (cext: 0.062) ruby 3.3.0 YJIT: 0.118 => 0.113 (cext: 0.053) truffleruby JVM: 0.101 => 0.054 jruby 9.4.6.0: 0.162 => 0.219 jruby 9.4.6.0 indy: 0.078 => 0.086 * For the record here are the numbers for using the String directly, without a StringIO-like object: ruby 3.3.0: 0.215 => 0.234 (cext: 0.062) ruby 3.3.0 YJIT: 0.118 => 0.111 (cext: 0.053) truffleruby native: 0.101 => 0.053 jruby 9.4.6.0: 0.162 => 0.195 jruby 9.4.6.0 indy: 0.078 => 0.082 As we can see, that extra object adds a non-trivial overhead on CRuby interpreter and JRuby. But we need to make it possible to use StringIO and SimpleStringIO interchangeably. https://github.com/ruby/prism/commit/938677cbd2
