Ruby 3.2 support

[eregon]

We are working on Ruby 3.2 support for the next release (23.1).

Any help is appreciated whether it is:

• implementing one of the Ruby 3.2 changes in TruffleRuby, and ensuring it is tested in specs or MRI tests and otherwise add specs. If adding specs please leave a comment here to mention you are working on adding these specs to avoid conflicts & duplicated work.
• adding specs for Ruby 3.2 changes, which is best done in ruby/spec directly, see https://github.com/ruby/spec/issues/1016

To make it easier to find good getting-started issues, I annotated items with easy, medium and hard. There is also pure ruby for changes which should only affect Ruby code and not require any change to Java sources or any Java knowledge. If there is no pure ruby then some Java code is involved, but it should still be fairly straightforward if easy or medium. hard typically requires more knowledge about TruffleRuby implementation details. [import] means this needs the import of Ruby 3.2 sources to happen first.

If you'd like to start on some task please mention it here or edit the description directly for committers (to avoid duplicated work).

Currently RUBY_VERSION is still 3.1.x. So to work on 3.2 changes, follow this documentation.

Full list of changes for Ruby 3.2.0

NOTE: https://rubyreferences.github.io/rubychanges/3.2.html gives more details for many features and changes.

From https://github.com/ruby/ruby/blob/master/doc/NEWS/NEWS-3.2.0.md:

This document is a list of user-visible feature changes since the 3.1.0 release, except for bug fixes.

Note that each entry is kept to a minimum, see links for details.

Language changes

• [x] [parser, YARP] Anonymous rest and keyword rest arguments can now be passed as arguments, instead of just used in method parameters. [Feature #18351]

  def foo(*)
    bar(*)
  end
  def baz(**)
    quux(**)
  end
  

• [x] [medium, java] A proc that accepts a single positional argument and keywords will no longer autosplat. [Bug #18633]

  proc{|a, **k| a}.call([1, 2])
  # Ruby 3.1 and before
  # => 1
  # Ruby 3.2 and after
  # => [1, 2]
  

• [ ] [medium, java] (@andrykonchin) Constant assignment evaluation order for constants set on explicit objects has been made consistent with single attribute assignment evaluation order. With this code:

  foo::BAR = baz
  

  foo is now called before baz. Similarly, for multiple assignments to constants, left-to-right evaluation order is used. With this code:

  foo1::BAR1, foo2::BAR2 = baz1, baz2
  

  The following evaluation order is now used:

  1. foo1
  2. foo2
  3. baz1
  4. baz2

  [Bug #15928]

• [x] [parser, YARP, need to implement Find pattern in translator] "Find pattern" is no longer experimental. [Feature #18585]

• [x] @eregon Methods taking a rest parameter (like *args) and wishing to delegate keyword arguments through foo(*args) must now be marked with ruby2_keywords (if not already the case). In other words, all methods wishing to delegate keyword arguments through *args must now be marked with ruby2_keywords, with no exception. This will make it easier to transition to other ways of delegation once a library can require Ruby 3+. Previously, the ruby2_keywords flag was kept if the receiving method took *args, but this was a bug and an inconsistency. A good technique to find the potentially-missing ruby2_keywords is to run the test suite, for where it fails find the last method which must receive keyword arguments, use puts nil, caller, nil there, and check each method/block on the call chain which must delegate keywords is correctly marked as ruby2_keywords. [Bug #18625] [Bug #16466]

  def target(**kw)
  end
  
  # Accidentally worked without ruby2_keywords in Ruby 2.7-3.1, ruby2_keywords
  # needed in 3.2+. Just like (*args, **kwargs) or (...) would be needed on
  # both #foo and #bar when migrating away from ruby2_keywords.
  ruby2_keywords def bar(*args)
    target(*args)
  end
  
  ruby2_keywords def foo(*args)
    bar(*args)
  end
  
  foo(k: 1)
  

Core classes updates

Note: We're only listing outstanding class updates.

Fiber

• [ ] [medium, java] Introduce Fiber.[] and Fiber.[]= for inheritable fiber storage. Introduce Fiber#storage and Fiber#storage= (experimental) for getting and resetting the current storage. Introduce Fiber.new(storage:) for setting the storage when creating a fiber. [Feature #19078]

  Existing Thread and Fiber local variables can be tricky to use. Thread-local variables are shared between all fibers, making it hard to isolate, while Fiber-local variables can be hard to share. It is often desirable to define unit of execution ("execution context") such that some state is shared between all fibers and threads created in that context. This is what Fiber storage provides.

  def log(message)
    puts "#{Fiber[:request_id]}: #{message}"
  end
  
  def handle_requests
    while request = read_request
      Fiber.schedule do
        Fiber[:request_id] = SecureRandom.uuid
  
        request.messages.each do |message|
          Fiber.schedule do
            log("Handling #{message}") # Log includes inherited request_id.
          end
        end
      end
    end
  end
  

  You should generally consider Fiber storage for any state which you want to be shared implicitly between all fibers and threads created in a given context, e.g. a connection pool, a request id, a logger level, environment variables, configuration, etc.

Fiber::Scheduler

• [ ] [needs other fiber scheduler parts first] Introduce Fiber::Scheduler#io_select for non-blocking IO.select. [Feature #19060]

IO

• [x] [hard, java] Introduce IO#timeout= and IO#timeout which can cause IO::TimeoutError to be raised if a blocking operation exceeds the specified timeout. [Feature #18630]

  STDIN.timeout = 1
  STDIN.read # => Blocking operation timed out! (IO::TimeoutError)
  

• [x] @moste00 [easy, pure ruby] Introduce IO.new(..., path:) and promote File#path to IO#path. [Feature #19036]

Class

• [x] [easy, java] Class#attached_object, which returns the object for which the receiver is the singleton class. Raises TypeError if the receiver is not a singleton class. [Feature #12084]

  class Foo; end
  
  Foo.singleton_class.attached_object        #=> Foo
  Foo.new.singleton_class.attached_object    #=> #<Foo:0x000000010491a370>
  Foo.attached_object                        #=> TypeError: `Foo' is not a singleton class
  nil.singleton_class.attached_object        #=> TypeError: `NilClass' is not a singleton class
  

Data

• [x] @moste00 [medium, pure ruby] New core class to represent simple immutable value object. The class is similar to Struct and partially shares an implementation, but has more lean and strict API. [Feature #16122]

  Measure = Data.define(:amount, :unit)
  distance = Measure.new(100, 'km')            #=> #<data Measure amount=100, unit="km">
  weight = Measure.new(amount: 50, unit: 'kg') #=> #<data Measure amount=50, unit="kg">
  weight.with(amount: 40)                      #=> #<data Measure amount=40, unit="kg">
  weight.amount                                #=> 50
  weight.amount = 40                           #=> NoMethodError: undefined method `amount='
  

Encoding

• [x] [easy, pure ruby] Encoding#replicate has been deprecated and will be removed in 3.3. [Feature #18949]
• [ ] [easy, java, might already be the case] The dummy Encoding::UTF_16 and Encoding::UTF_32 encodings no longer try to dynamically guess the endian based on a byte order mark. Use Encoding::UTF_16BE/UTF_16LE and Encoding::UTF_32BE/UTF_32LE instead. This change speeds up getting the encoding of a String. [Feature #18949]
• [x] [medium, java] Limit maximum encoding set size by 256. If exceeding maximum size, EncodingError will be raised. [Feature #18949]

Enumerator

• [x] [easy, pure ruby] Enumerator.product has been added. Enumerator::Product is the implementation. [Feature #18685]

Exception

• [x] [easy, some ruby, some java] Exception#detailed_message has been added. The default error printer calls this method on the Exception object instead of #message. [Feature #18564]

Hash

• [x] Hash#shift now always returns nil if the hash is empty, instead of returning the default value or calling the default proc. [Bug #16908]

Integer

• [x] @nirvdrum [easy, java] Integer#ceildiv has been added. [Feature #18809]

Kernel

• [ ] [easy, java] Kernel#binding raises RuntimeError if called from a non-Ruby frame (such as a method defined in C). [Bug #18487]

MatchData

• [x] @rwstauner [easy, java] MatchData#byteoffset has been added. [Feature #13110]
• [x] @rwstauner [easy, pure ruby] MatchData#deconstruct has been added. [Feature #18821]
• [x] @rwstauner [easy, pure ruby] MatchData#deconstruct_keys has been added. [Feature #18821]

Module

• [x] [already done, just need to untag specs/tests] Module.used_refinements has been added. [Feature #14332]
• [x] [easy, java] Module#refinements has been added. [Feature #12737]
• [x] [medium, java] Module#const_added has been added. [Feature #17881]
• [x] [easy, java] Module#undefined_instance_methods has been added. [Feature #12655]

Proc

• [x] [easy, seems already be the case, need to untag specs] Proc#dup returns an instance of subclass. [Bug #17545]
• [x] [easy, java] Proc#parameters now accepts lambda keyword. [Feature #15357]

Process

• [x] Added RLIMIT_NPTS constant to FreeBSD platform

Regexp

• [x] The cache-based optimization is introduced. Many (but not all) Regexp matching is now in linear time, which will prevent regular expression denial of service (ReDoS) vulnerability. [Feature #19104]

• [ ] [medium, java] Regexp.linear_time? is introduced. [Feature #19194]

• [x] @rwstauner [easy, pure ruby] Regexp.new now supports passing the regexp flags not only as an Integer, but also as a String. Unknown flags raise ArgumentError. Otherwise, anything other than true, false, nil or Integer will be warned. [Feature #18788]

• [ ] [hard, java, would need changes in tregex backtracker] Regexp.timeout= has been added. Also, Regexp.new new supports timeout keyword. See [Feature #17837]

Refinement

• [x] [easy, java] Refinement#refined_class has been added. [Feature #12737]

Set

• [x] [easy, pure Ruby] Set is now available as a built-in class without the need for require "set". [Feature #16989] It is currently autoloaded via the Set constant or a call to Enumerable#to_set.

String

• [x] [easy, java] String#byteindex and String#byterindex have been added. [Feature #13110]
• [ ] [medium, depends on jcodings] Update Unicode to Version 15.0.0 and Emoji Version 15.0. [Feature #18639] (also applies to Regexp)
• [x] [medium, java] String#bytesplice has been added. [Feature #18598]
• [x] [easy, pure ruby] String#dedup has been added as an alias to String#-@. [Feature #18595]

Struct

• [x] @rwstauner [easy, pure ruby] A Struct class can also be initialized with keyword arguments without keyword_init: true on Struct.new [Feature #16806]

  Post = Struct.new(:id, :name)
  Post.new(1, "hello") #=> #<struct Post id=1, name="hello">
  # From Ruby 3.2, the following code also works without keyword_init: true.
  Post.new(id: 1, name: "hello") #=> #<struct Post id=1, name="hello">
  

Thread

• [x] [medium, java] Thread.each_caller_location is added. [Feature #16663]

Thread::Queue

• [x] [medium, java] Thread::Queue#pop(timeout: sec) is added. [Feature #18774]

Thread::SizedQueue

• [x] [medium, java] Thread::SizedQueue#pop(timeout: sec) is added. [Feature #18774]
• [x] [medium, java] Thread::SizedQueue#push(timeout: sec) is added. [Feature #18944]

Time

• [x] @rwstauner [easy, pure ruby] Time#deconstruct_keys is added, allowing to use Time instances in pattern-matching expressions [Feature #19071]

• [ ] [medium] Time.new now can parse a string like generated by Time#inspect and return a Time instance based on the given argument. [Feature #18033]

SyntaxError

• [ ] [easy, java] SyntaxError#path has been added. [Feature #19138]

TracePoint

• [x] TracePoint#binding now returns nil for c_call/c_return TracePoints. [Bug #18487]
• [ ] [medium, java, target_thread not yet implemented] TracePoint#enable target_thread keyword argument now defaults to the current thread if a block is given and target and target_line keyword arguments are not passed. [Bug #16889]

UnboundMethod

• [x] @rwstauner [easy, java] UnboundMethod#== returns true if the actual method is same. For example, String.instance_method(:object_id) == Array.instance_method(:object_id) returns true. [Feature #18798]

• [x] @rwstauner [easy, ruby+java] UnboundMethod#inspect does not show the receiver of instance_method. For example String.instance_method(:object_id).inspect returns "#<UnboundMethod: Kernel#object_id()>" (was "#<UnboundMethod: String(Kernel)#object_id()>").

Stdlib updates

CGI

• [x] [import] CGI.escapeURIComponent and CGI.unescapeURIComponent are added. [Feature #18822]

Coverage

• [ ] [hard, java] Coverage.setup now accepts eval: true. By this, eval and related methods are able to generate code coverage. [Feature #19008]

• [x] [easy, pure ruby] Coverage.supported?(mode) enables detection of what coverage modes are supported. [Feature #19026]

Date

• [x] [easy, pure ruby] Added Date#deconstruct_keys and DateTime#deconstruct_keys same as [Feature #19071]

FileUtils

• [x] [import] Add FileUtils.ln_sr method and relative: option to FileUtils.ln_s. [Feature #18925]

IRB

• [x] [import] debug.gem integration commands have been added: debug, break, catch, next, delete, step, continue, finish, backtrace, info * They work even if you don't have gem "debug" in your Gemfile. * See also: What's new in Ruby 3.2's IRB?
• [x] [import] More Pry-like commands and features have been added. * edit and show_cmds (like Pry's help) are added. * ls takes -g or -G option to filter out outputs. * show_source is aliased from $ and accepts unquoted inputs. * whereami is aliased from @.

Net::Protocol

• [x] [import] Improve Net::BufferedIO performance. [GH-net-protocol-14]

Compatibility issues

• [x] [easy, pure ruby] String#to_c currently treat a sequence of underscores as an end of Complex string. [Bug #19087]

• [x] [easy, pure ruby] Now ENV.clone raises TypeError as well as ENV.dup [Bug #17767]

Removed constants

The following deprecated constants are removed.

• [x] [easy] Fixnum and Bignum [Feature #12005]
• [x] [easy, pure ruby] Random::DEFAULT [Feature #17351]
• [x] [easy, pure ruby] Struct::Group
• [x] [easy, pure ruby] Struct::Passwd

Removed methods

• [x] [easy, pure ruby] Dir.exists? [Feature #17391]
• [x] [easy, pure ruby] File.exists? [Feature #17391]
• [x] [easy] Kernel#=~ [Feature #15231]

Error printer

• [x] Ruby no longer escapes control characters and backslashes in an error message. [Feature #18367]

Constant lookup when defining a class/module

• [ ] [medium, java] When defining a class/module directly under the Object class by class/module statement, if there is already a class/module defined by Module#include with the same name, the statement was handled as "open class" in Ruby 3.1 or before. Since Ruby 3.2, a new class is defined instead. [Feature #18832]

Stdlib compatibility issues

• [x] Psych no longer bundles libyaml sources. And also Fiddle no longer bundles libffi sources. Users need to install the libyaml/libffi library themselves via the package manager like apt, yum, brew, etc.

  Psych and fiddle supported the static build with specific version of libyaml and libffi sources. You can build psych with libyaml-0.2.5 like this.

  $ ./configure --with-libyaml-source-dir=/path/to/libyaml-0.2.5
  

  And you can build fiddle with libffi-3.4.4 like this.

  $ ./configure --with-libffi-source-dir=/path/to/libffi-3.4.4
  

  [Feature #18571]

• [x] [import] Check cookie name/path/domain characters in CGI::Cookie. [CVE-2021-33621]

• [x] [import] URI.parse return empty string in host instead of nil. [sec-156615]

C API updates

Added C APIs

• [x] [easy, C, can just ignore the argument] VALUE rb_hash_new_capa(long capa) was added to created hashes with the desired capacity.
• [x] [won't do, CRuby/GIL specific] rb_internal_thread_add_event_hook and rb_internal_thread_add_event_hook were added to instrument threads scheduling. The following events are available:
  • RUBY_INTERNAL_THREAD_EVENT_STARTED
  • RUBY_INTERNAL_THREAD_EVENT_READY
  • RUBY_INTERNAL_THREAD_EVENT_RESUMED
  • RUBY_INTERNAL_THREAD_EVENT_SUSPENDED
  • RUBY_INTERNAL_THREAD_EVENT_EXITED
• [ ] [medium, C] rb_debug_inspector_current_depth and rb_debug_inspector_frame_depth are added for debuggers.

Removed C APIs

The following deprecated APIs are removed.

• [x] [easy] rb_cData variable.
• [x] [import] "taintedness" and "trustedness" functions. [Feature #16131]

Implementation improvements

• [ ] [probably already done, need to check specs/tests for it] Fixed several race conditions in Kernel#autoload. [Bug #18782]

[eregon]

The 3.2 import has been merged in https://github.com/oracle/truffleruby/commit/66ca27b87a196707d3822bac2aaca201bb1600d0, so now RUBY_VERSION is "3.2.2" and it's easier implement the rest of 3.2 features. Contributions welcome!

[AnuravModak]

is there anything left to do? I have joined Oracle recently as a fresher, so anything under easy tag would be convenient for me in java or in C. @eregon

[moste00]

Hey, I'm currently working on Feature #19036 !

Just a heads up because I can't edit the issue directly.

[eregon]

@moste00 noted. @AnuravModak I'd say just pick an easy one and mention it here.

[AnuravModak]

So, i am choosing [Feature #12084], is it open for resolving, like i am little confused how to check whether it is opened or not? like i followed the link and gone through the discussion that was not very conclusive Basically, I didn't find any merge or closed tag for this feature in this page so I chose this one, can somebody help here??

[eregon]

I edited the issue description to mark you for that item. Feel free to ask questions on Slack (either public GraalVM Slack or the Oracle one).

[moste00]

I'm taking Feature #16122, the one about the new Data class.

[sarvo123]

hii , can i work on this Feature Feature #16989

[eregon]

@sarvo123 Sure, feel free to open a PR for it.

[sempervictus]

I'm taking Feature #16122, the one about the new Data class.

Any luck with this? Seems folks are starting to actually use it in production code.

[moste00]

@sempervictus Hey !

I have some basic skeleton in place, basically you can create classes and instances and ask instances for members but not much else. I got held up the last couple of weeks but I plan to finish it and make a PR in the next 2 weeks, fingers crossed.

[sempervictus]

Thanks @moste00 - OpenProject decided to go all in on the 3.2 syntax and i'm having to roll back their Data.define stuff (mildly redundant IMO, but i've been around since green threads were cool and people used continuations, the language has seen worse). If you have a branch somewhere i'm happy to test it - we maintain our own packaging for this stuff on a fork of Arch

[sempervictus]

There's a core syntax change missing from the description from what i can tell. Seems MRI now allows assignment in the def line:

def method_name(arg) = call_something_else(arg)

which has to get rewritten to

def method_name(arg)
  call_something_else(arg)
end

to prevent crashes on TruffleRuby

[sempervictus]

Case statements using pattern matches are also not handled correctly by TruffleRuby in 3.2 mode:

    case /Storages::(?'provider_name'.*)Storage/.match(provider_type)
    in provider_name:
      provider_name.downcase
    else
      raise ArgumentError,

produces syntax error, unexpected keyword_in:

[eregon]

@moste00 Could you open a draft PR with what you have? Data should be pretty easy to add. Most of the effort might be adding specs but there are already some.

@sempervictus

There's a core syntax change missing from the description from what i can tell. Seems MRI now allows assignment in the def line:

That will be fixed by the new parser, you can follow https://github.com/oracle/truffleruby/issues/3117 for that. There is good progress there, it should be done by the next release.

Case statements using pattern matches are also not handled correctly by TruffleRuby in 3.2 mode

TruffleRuby supports the array pattern matching by using the --pattern-matching flag, but not the hash pattern matching yet. Hence the flag to consider it all not implemented to avoid surprises. We'll need https://github.com/oracle/truffleruby/issues/3117 and then implementing hash pattern matching to address that.

[moste00]

@eregon @sempervictus Sorry for being late, PR here https://github.com/oracle/truffleruby/pull/3341.

[eregon]

Data is supported now on truffleruby-head/dev.

[andrykonchin]

I am working on A proc that accepts a single positional argument and keywords will no longer autosplat. [Bug #18633]

[andrykonchin]

I am working on Anonymous rest and keyword rest arguments can now be passed as arguments, instead of just used in method parameters. [Feature #18351]

[andrykonchin]

I am working on Constant assignment evaluation order for constants set on explicit objects has been made consistent with single attribute assignment evaluation order

[andrykonchin]

I am working on Class#attached_object

[andrykonchin]

Working on removing deprecated methods.

[andrykonchin]

Working on removing deprecated constants.

[rwstauner]

I'll look at 19071, Time#deconstruct_keys. It seems like we have {Date,DateTime}#deconstruct_keys from date_core.c

[rwstauner]

looking at 18788 Regexp.new now supports passing the regexp flags as a string.

[andrykonchin]

Working on Set is now available as a built-in class without the need for require "set". [Feature #16989]

[rwstauner]

👋 Manef from Shopify, Wanted to confirm if the following : [easy, pure ruby] Encoding#replicate has been deprecated and will be removed in 3.3. [[Feature #18949](https://bugs.ruby-lang.org/issues/18949)] On the CRuby side it seems to be targeted for 3.3 : https://bugs.ruby-lang.org/issues/18949

Is still targeting 3.2 ? Ty !

@manefz It's deprecated in 3.2 and removed in 3.3. So this item is to deprecate it, that is emit the same warning as CRuby 3.2 does when using that method.
