Issue #20062 has been reported by osyo (manga osyo). ---------------------------------------- Bug #20062: Numbered parameters are broken in Ruby 3.3-dev https://bugs.ruby-lang.org/issues/20062 * Author: osyo (manga osyo) * Status: Open * Priority: Normal * ruby -v: ruby 3.3.0dev (2023-12-13T13:16:11Z master f390c51b15) [x86_64-linux] * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- Define Numbered parameters and a method in one block and then reference Numbered parameters in another block, you will get a SyntaxError in Ruby 3.3. This is not a problem in Ruby 3.2. ```ruby 'a'.tap do p _1 def f1; end end 'a'.tap do p _1 end __END__ output: Ruby 3.2.2 => "a" "a" Ruby 3.3.0dev(2023-12-13T13:16:11Z master f390c51b15) => /path/to/test.rb: /path/to/test.rb:8: numbered parameter is already used in (SyntaxError) /path/to/test.rb:2: outer block here ``` I noticed this while checking the operation of https://bugs.ruby-lang.org/issues/18966. I haven't checked, but https://bugs.ruby-lang.org/issues/19619 may be related. -- https://bugs.ruby-lang.org/

[ruby-core:111306] [Ruby master Feature#19236] Allow to create hashes with a specific capacity from Ruby
by byroot (Jean Boussier) 06 Jul '24

Issue #19236 has been reported by byroot (Jean Boussier). ---------------------------------------- Feature #19236: Allow to create hashes with a specific capacity from Ruby https://bugs.ruby-lang.org/issues/19236 * Author: byroot (Jean Boussier) * Status: Open * Priority: Normal * Target version: 3.3 ---------------------------------------- Followup on [Feature #18683] which added a C-API for this purpose. Various protocol parsers such as Redis `RESP3` or `msgpack`, have to create hashes, and they know the size in advance. For efficiency, it would be preferable if they could directly allocate a Hash of the necessary size, so that large hashes wouldn't cause many re-alloccations and re-hash. `String` and `Array` both already offer similar APIs: ```ruby String.new(capacity: XXX) Array.new(XX) / rb_ary_new_capa(long) ``` However there's no such public API for Hashes in Ruby land. ### Proposal I think `Hash` should have a way to create a new hash with a `capacity` parameter. The logical signature of `Hash.new(capacity: 1000)` was deemed too incompatible in [Feature #18683]. @Eregon proposed to add `Hash.create(capacity: 1000)`. -- https://bugs.ruby-lang.org/

[ruby-core:115595] [Ruby master Bug#20043] `defined?` checks for method existence but only sometimes
by tenderlovemaking (Aaron Patterson) 06 Jun '24

Issue #20043 has been reported by tenderlovemaking (Aaron Patterson). ---------------------------------------- Bug #20043: `defined?` checks for method existence but only sometimes https://bugs.ruby-lang.org/issues/20043 * Author: tenderlovemaking (Aaron Patterson) * Status: Open * Priority: Normal * ruby -v: ruby 3.3.0dev (2023-12-05T21:25:34Z master 56eccb350b) [arm64-darwin23] * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- When an expression is passed to `defined?`, it will _sometimes_ check if a method in a sub-expression is defined and sometimes it won't. For example: ``` $ ./miniruby -e'p defined?(a)' nil $ ./miniruby -e'p defined?([a])' nil ``` In the above case, Ruby will check whether or not the method `a` is defined, and it returns `nil`. However, if you use a splat, it will not check: ``` $ ./miniruby -e'p defined?([*a])' "expression" ``` The same thing seems to happen with method parameters: ``` $ ./miniruby -e'p defined?(itself)' "method" $ ./miniruby -e'p defined?(itself(a))' nil $ ./miniruby -e'p defined?(itself(*a))' "method" ``` Oddly, `defined?` will check contents of arrays, but _won't_ check contents of hashes: ``` $ ./miniruby -e'p defined?([[[[a]]]])' nil $ ./miniruby -e'p defined?({ a => a })' "expression" ``` I think all of the cases that refer to `a` should check whether or not `a` is defined regardless of splats or hashes. -- https://bugs.ruby-lang.org/

[ruby-core:115334] [Ruby master Feature#19998] Emit deprecation warnings when the old (non-Typed) Data_XXX API is used
by byroot (Jean Boussier) 06 Jun '24

06 Jun '24

Issue #19998 has been reported by byroot (Jean Boussier). ---------------------------------------- Feature #19998: Emit deprecation warnings when the old (non-Typed) Data_XXX API is used https://bugs.ruby-lang.org/issues/19998 * Author: byroot (Jean Boussier) * Status: Open * Priority: Normal ---------------------------------------- The replacement API was introduced in Ruby 1.9.2 (2010) [Feature #3064], and the old untyped data API was marked a deprecated in the documentation as of Ruby 2.3.0 (2015): https://github.com/ruby/ruby/commit/98544c372d948717de22afc86d162e411f1fb5f1 However, as of today, no deprecation warning of any sort is emitted when the API is used. Ultimately removing the old untyped API would allow to easily reclaim 8B on every `T_DATA` which could be used by the newly introduced embedded TypedData objects https://github.com/ruby/ruby/pull/7440 Was there any discussions about removing the old API at some point? Could we emit a warning when the API is used? Either verbose or non-verbose, to at least surface the issue to gem owners? This would help drive the effort to fix outdated gems, allowing to eventually remove this old API in the future. Looking at our big applications dependencies, there seem to be a small minority of gems still using the old API: - https://rubygems.org/gems/unf_ext - https://rubygems.org/gems/rotoscope - https://rubygems.org/gems/re2 - https://rubygems.org/gems/mysql2 Migrating them over doesn't seem too hard. -- https://bugs.ruby-lang.org/

[ruby-core:114038] [Ruby master Bug#19749] Confirm correct behaviour when attaching private method with `#define_method`
by itarato (Peter Arato) 06 Jun '24

Issue #19749 has been reported by itarato (Peter Arato). ---------------------------------------- Bug #19749: Confirm correct behaviour when attaching private method with `#define_method` https://bugs.ruby-lang.org/issues/19749 * Author: itarato (Peter Arato) * Status: Open * Priority: Normal * ruby -v: 3.3.0 * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- This issue is a special case of https://bugs.ruby-lang.org/issues/19745: Should dynamically added private methods via `.singleton_class.send(:define_method,...` be accessible publicly? See the following example? ```ruby private def bar; end foo = Object.new foo.singleton_class.send(:define_method, :bar, method(:bar)) foo.bar # No error. ``` The script above runs fine on latest Ruby 3.3. Is this correct to ignore the fact that the added method (method(:bar)) is private? This came up during a TruffleRuby investigation (https://github.com/oracle/truffleruby/issues/3134) where the result for the same script is: `private method 'bar' called for #<Object:0xc8> (NoMethodError)` -- https://bugs.ruby-lang.org/

[ruby-core:112538] [Ruby master Feature#19458] Expose HEREDOC identifier
by joelhawksley (Joel Hawksley) 04 Jun '24

Issue #19458 has been reported by joelhawksley (Joel Hawksley). ---------------------------------------- Feature #19458: Expose HEREDOC identifier https://bugs.ruby-lang.org/issues/19458 * Author: joelhawksley (Joel Hawksley) * Status: Open * Priority: Normal ---------------------------------------- I’d like to have access to the HEREDOC identifier. In the ViewComponent framework I help maintain, we added a method to declare a template as such: ```ruby class Component erb_template <<~ERB <h1>Hello, <%= @name %>!</h1> ERB end ``` I'd prefer to be able to write: ```ruby class Component template <<~ERB <h1>Hello, <%= @name %>!</h1> ERB end ``` And be able to see that the argument passed to `.template` was from a HEREDOC with an `ERB` identifier, which would allow me to use the correct template handler to compile the template. I could see this being implemented: 1) As a new property of String, such as `identifier` or `heredoc_identifier`. 2) By having HEREDOCs return a subclass of String that includes an `identifier` property. I'd be happy to work on implementing this change. -- https://bugs.ruby-lang.org/
