Issue #21381 has been reported by herwin (Herwin W). ---------------------------------------- Bug #21381: Different error messages when mixing `it` and `_1` in block for Prism and parse.y https://bugs.ruby-lang.org/issues/21381 * Author: herwin (Herwin W) * Status: Open * ruby -v: ruby 3.4.4 (2025-05-14 revision a38531fd3f) +PRISM [x86_64-linux] and ruby 3.4.4 (2025-05-14 revision a38531fd3f) [x86_64-linux] * Backport: 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN ---------------------------------------- ``` $ ruby -v -e 'proc { it + _1 }' ruby 3.4.4 (2025-05-14 revision a38531fd3f) +PRISM [x86_64-linux] -e: -e:1: syntax error found (SyntaxError) > 1 | proc { it + _1 } | ^~ numbered parameters are not allowed when 'it' is already used $ ruby -v --parser=parse.y -e 'proc { it + _1 }' ruby 3.4.4 (2025-05-14 revision a38531fd3f) [x86_64-linux] -e:1: 'it' is already used in -e:1: current block here proc { it + _1 } ruby: compile error (SyntaxError) ``` and the other way around: ``` $ ruby -v -e 'proc { _1 + it}' ruby 3.4.4 (2025-05-14 revision a38531fd3f) +PRISM [x86_64-linux] -e: -e:1: syntax error found (SyntaxError) > 1 | proc { _1 + it} | ^~ `it` is not allowed when a numbered parameter is already used $ ruby -v --parser=parse.y -e 'proc { _1 + it}' ruby 3.4.4 (2025-05-14 revision a38531fd3f) [x86_64-linux] -e:1: numbered parameter is already used in -e:1: current block here proc { _1 + it} ruby: compile error (SyntaxError) ``` It would expect the relevant part of messages to match. To be clear, I would consider this the relevant parts: ``` numbered parameters are not allowed when 'it' is already used 'it' is already used in ``` and ``` `it` is not allowed when a numbered parameter is already used numbered parameter is already used ``` -- https://bugs.ruby-lang.org/

Issue #21206 has been reported by shyouhei (Shyouhei Urabe). ---------------------------------------- Bug #21206: Segmentation fault on ISeq#to_binary https://bugs.ruby-lang.org/issues/21206 * Author: shyouhei (Shyouhei Urabe) * Status: Open * ruby -v: ruby 3.4.2 (2025-02-15 revision d2930f8e7a) +PRISM +GC [aarch64-linux-gnu] * Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN ---------------------------------------- Found this SEGV using bootsnap. This could well be architecture dependent because of ISeqs being so by nature.

[ruby-core:122184] [Ruby Misc#21350] Bundled gems lack online documentation
by osyoyu (Daisuke Aritomo) 04 Jun '25

Issue #21350 has been reported by osyoyu (Daisuke Aritomo). ---------------------------------------- Misc #21350: Bundled gems lack online documentation https://bugs.ruby-lang.org/issues/21350 * Author: osyoyu (Daisuke Aritomo) * Status: Open ---------------------------------------- Libraries which have been converted into bundled gems seem to have no online documentation. For example, `csv` had its documentation inside docs.ruby-lang.org up to Ruby 3.3: https://docs.ruby-lang.org/en/3.3/CSV.html but after it has turned into a bundled gem, there is no online documentation (try searching in https://docs.ruby-lang.org/en/3.4/) This is the case for all bundled gems, including major modules such as `Base64` (missing since 3.4 docs) and `Logger` (missing since master docs). Given that these libraries are still `require`able without any special installation, it would be nice to have their documentation on docs.ruby-lang.org (or somewhere online reachable from Google). -- https://bugs.ruby-lang.org/

[ruby-core:119645] [Ruby master Bug#20854] Some bundled gems are not installed starting with 007c75ce4c66243e41144c6977e5ccbf4ab71c93

Issue #20854 has been reported by jvreeland (Justin Vreeland). ---------------------------------------- Bug #20854: Some bundled gems are not installed starting with 007c75ce4c66243e41144c6977e5ccbf4ab71c93 https://bugs.ruby-lang.org/issues/20854 * Author: jvreeland (Justin Vreeland) * Status: Open * ruby -v: Building ruby from master * Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- I noticed in ruby 3.4.0 preview 2 that some bundled gems weren't being installed any more. I'm running in the same environment each time and bundled gems are installed fine with 3.3 or with the mentioned commit reverted. I bisected this from a version that did install the gems to 007c75ce4c66243e41144c6977e5ccbf4ab71c93 . The comment in that commit does indicate that it's mean to skip games if the gems are not found or can't be built but the final message is 'not found in bundled_gems'. I'm unsure if this is this is working as intended. When my build finishes I see the following line in the log: ``` installing bundled gem cache: /home/user/ruby/build/.rubies/bisect/lib/ruby/gems/3.4.0+0/cache skipped bundled gems: bigdecimal-3.1.8.gem not found in bundled_gems debug-1.9.2.gem not found in bundled_gems nkf-0.2.0.gem not found in bundled_gems/rac racc-1.8.1.gem not found in bundled_gems rbs-3.6.1.gem not found in bundled_gems syslog-0.1.2.gem not found in bundled_gems typeprof-0.30.0.gem not found in bundled_gems ``` I see racc in bundled gems and cached in downloads. I don't see any files named gem.build_complete or errors concerning gem building or missing C extensions in my build logs. Is there additional configure flags or dependencies I need to include the bundled gems in the upcoming 3.4.0 ruby release? I followed the instructions at: https://docs.ruby-lang.org/en/master/contributing/building_ruby_md.html to build: ``` git clean -dxf git checkout -f autoreconf -fi mkdir build pushd build ../configure --prefix=(pwd)/.rubies/bisect make -j(nproc) make install popd find build/.rubies/bisect -name 'racc' | grep . ``` -- https://bugs.ruby-lang.org/

[ruby-core:122235] [Ruby Feature#21361] Set execution file and line
by kddnewton (Kevin Newton) 03 Jun '25

Issue #21361 has been reported by kddnewton (Kevin Newton). ---------------------------------------- Feature #21361: Set execution file and line https://bugs.ruby-lang.org/issues/21361 * Author: kddnewton (Kevin Newton) * Status: Open ---------------------------------------- I'd like to be able to set the execution file and execution line for the purpose of generated Ruby code. My specific use case is the Ruby files that are templated in Prism, but I also believe it would be beneficial for ERB. The functionality I'm looking for effectively mirrors the `#line` macro in C. The goal would be for this to be entirely statically analyzable, so whatever syntax ends up being used would have to be required to be constant. A couple of options for this would be: * An entirely new syntax construct (`__SOURCE__ 5 "foo.erb"`) * Re-using existing syntax constructs (`__LINE__ = 5; __FILE__ = "foo.erb"`) * A magic comment (`# -*- source-line: 5; source-file: foo.erb -*-` or `# source: 5 foo.erb`) I don't particularly care which one is selected, it's just the end-result that I'm looking for that we can mark the source line and file within the generated code. -- https://bugs.ruby-lang.org/

[ruby-core:122042] [Ruby Bug#21330] Namespace: Class and Module frozen status is not namespace

Issue #21330 has been reported by byroot (Jean Boussier). ---------------------------------------- Bug #21330: Namespace: Class and Module frozen status is not namespace https://bugs.ruby-lang.org/issues/21330 * Author: byroot (Jean Boussier) * Status: Open * Backport: 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN ---------------------------------------- ```ruby File.write("/tmp/test.rb", <<~'RUBY') Hash.freeze RUBY ns = Namespace.new ns.require("/tmp/test.rb") class Hash def monkey_patch end end ``` Expected behavior: Since the monkey patch is in a different namespace, I'd expect it to not impact code that is running in another namespace. Actual behavior: ``` test.rb:9:in '<class:Hash>': can't modify frozen class: Hash (FrozenError) ``` The class is frozen globally, breaking code in other namespaces. Is this by design, or does that mean the frozen status need to be moved in the `classext_t` as well? cc @tagomoris -- https://bugs.ruby-lang.org/

[ruby-core:122350] [Ruby Feature#21387] Proposal to add Data#[]
by ybiquitous (Masafumi Koba) 02 Jun '25

Issue #21387 has been reported by ybiquitous (Masafumi Koba). ---------------------------------------- Feature #21387: Proposal to add Data#[] https://bugs.ruby-lang.org/issues/21387 * Author: ybiquitous (Masafumi Koba) * Status: Open ---------------------------------------- ## Proposal I propose to add a new instance method `#[]` to the `Data` class, similar to [`Struct#[]`](https://docs.ruby-lang.org/en/3.4/Struct.html#method-i-5B-5D). If writing the method signature in RBS, it would be like this: ```ruby class Data def []: (name: String | Symbol) -> untyped end ``` Requirements: - `Data#[]` accepts a member name as a `Symbol` or `String`, e.g., `data[:id] == data["id"]`. - `Data#[]` returns a value associated with the given `name`, e.g., `data[:id] == data.id`. - `Data#[]` raises `NameError` if the given `name` is not one of the members, e.g., `data[:invalid]`. Note: Please assume that `data = Data.define(:id).new(id: 100)` is given in the examples above. ## Motivation In Active Support Core Extensions of Rails, I found a use case that `Data#[]` would be helpful with `Enumerable#pluck`. Please look at this example: ```ruby # data_test.rb require "bundler/inline" gemfile do source "https://rubygems.org" gem "activesupport", "8.0.2" end require "active_support/core_ext/enumerable" StructPerson = Struct.new(:name, :age) DataPerson = Data.define(:name, :age) struct_people = [ StructPerson.new("Bob", 25), ] puts "Struct:" puts "=> #{struct_people.pluck(:name)}" data_people = [ DataPerson.new("Charlie", 35), ] puts "Data:" begin puts "=> #{data_people.pluck(:name)}" rescue => e puts e.detailed_message(syntax_suggest: true) end ``` Running this script outputs below: ```shell $ ruby data_test.rb Struct: => ["Bob"] Data: undefined method '[]' for an instance of DataPerson (NoMethodError) map { |element| element[key] } ^^^^^ ``` Note: This output resulted on `ruby 3.4.4 (2025-05-14 revision a38531fd3f) +PRISM [arm64-darwin24]`. The error reason is that the `Enumerable#pluck` extension expects all the elements in the array to respond to `[]`. See also the `pluck` code here: https://github.com/rails/rails/blob/v8.0.2/activesupport/lib/active_support… If `Data#[]` was implemented as follows, ```ruby # data_patch.rb class Data def [](name) unless members.include?(name.to_sym) raise NameError, "no member '#{name}' in data" end public_send(name) end end ``` The script is successful: ```shell $ ruby -r ./data_patch.rb data_test.rb Struct: => ["Bob"] Data: => ["Charlie"] ``` Ref: - https://guides.rubyonrails.org/v8.0.2/active_support_core_extensions.html#p… - https://api.rubyonrails.org/v8.0.2/classes/Enumerable.html#method-i-pluck Although `Enumerable#pluck` is just an example, I guess that there would be other cases where `Data` objects should respond to `[]`. ## Reasoning From the long discussion in #16122 that introduced `Data`, I understand that `Data#[]` was rejected in #16122#note-28 because `[]` was like `Enumerable`. I also agree with rejecting `Data#each` since `Data` is not an `Enumerable`, but `[]` seems acceptable to me. Reasons: - `[]` is sometimes used for non-container objects, such as [`ActiveRecord::AttributeMethods#[]`](https://api.rubyonrails.org/v8.0.2/classes/ActiveRecord/AttributeMethods.html#method-i-5B-5D). - Considering `Data#to_h` is provided, it seems reasonable that we could access a `Data` member's value through `[]`. - From the similarity between `Struct` and `Data`, some people might expect `Hash`-like accessing via `[]`. - Unless `[]` is provided, we have to call `public_send` or convert to a hash via `to_h` when we want to get member values with names. It'd be inefficient and easy to make mistakes. Let me show an example: ```ruby Person = Data.define(:name, :age) charlie = Person.new("Charlie", 35) member_names_from_user_input = ["age", "hash"] # "hash" is a malicious input. # Using #public_send member_names_from_user_input.map { charlie.public_send(it) } #=> [35, -1363726049241242821] # Using #to_h and Hash#fetch with string keys member_names_from_user_input.map { charlie.to_h.fetch(it) } #=> key not found: "age" (KeyError) # Using #to_h and Hash#fetch with symbol keys member_names_from_user_input.map { charlie.to_h.fetch(it.to_sym) } #=> key not found: :hash (KeyError) # Using #[] member_names_from_user_input.map { charlie[it] } #=> no member 'hash' in data (NameError) ``` The last example is most elegant for the same goal. That's why I propose to add `Data#[]`. However, there might be downsides that I have overlooked, so I'd appreciate it if you could let me know. Thanks. -- https://bugs.ruby-lang.org/
