[ruby-core:120873] [Ruby master Bug#21111] RbConfig::CONFIG['CXX'] quietly set to "false" when Ruby cannot build C++ programs

Issue #21111 has been reported by stanhu (Stan Hu). ---------------------------------------- Bug #21111: RbConfig::CONFIG['CXX'] quietly set to "false" when Ruby cannot build C++ programs https://bugs.ruby-lang.org/issues/21111 * Author: stanhu (Stan Hu) * Status: Open * ruby -v: ruby 3.4.1 (2024-12-25 revision 48d4efcb85) +YJIT +PRISM [arm64-darwin24] * Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN ---------------------------------------- As reported in https://gitlab.com/gitlab-org/gitlab-development-kit/-/issues/2222 and https://trac.macports.org/ticket/70750, we've had numerous macOS users experience problems with compiling Ruby C++ extensions after upgrading to XCode 16. Users have had to fix their XCode setups and reinstall Ruby when this happens. It turns out that when Ruby can't build a CXX program, it essentially sets CXX to the `false` string. From https://github.com/ruby/ruby/blob/7317f96727725ca37ddb06011918deb841de371c/…: ``` AS_IF([test -n "${rb_there_is_in_fact_no_gplusplus_but_autoconf_is_cheating_us}"], [ AC_MSG_NOTICE([Test skipped due to lack of a C++ compiler.]) ], [test -n "${CXX}"], [ RUBY_WERROR_FLAG([ AC_MSG_CHECKING([whether CXXFLAGS is valid]) AC_LANG_PUSH(C++) AC_COMPILE_IFELSE([AC_LANG_PROGRAM([[@%:@include <cstdio>]], [[]])], [AC_MSG_RESULT(yes)],[ AC_MSG_RESULT(no) # The message mentions CXXFLAGS, but CPPFLAGS might also affects. AC_MSG_WARN([something wrong with CXXFLAGS="$CXXFLAGS"]) CXX=false ``` This causes C++ extensions, such as `unf_ext`, to fail while attempting to compile native extensions. There are no error messages because `false` is executed, so users only see: ``` Installing unf_ext 0.0.8.2 with native extensions Gem::Ext::BuildError: ERROR: Failed to build gem native extension. current directory: /Users/myuser/.rvm/gems/ruby-3.3.7/gems/unf_ext-0.0.8.2/ext/unf_ext /Users/kerrizor/.rvm/rubies/ruby-3.3.7/bin/ruby extconf.rb checking for -lstdc++... yes creating Makefile current directory: /Users/myuser/.rvm/gems/ruby-3.3.7/gems/unf_ext-0.0.8.2/ext/unf_ext make DESTDIR\= sitearchdir\=./.gem.20250203-69237-u2oi17 sitelibdir\=./.gem.20250203-69237-u2oi17 clean current directory: /Users/myuser/.rvm/gems/ruby-3.3.7/gems/unf_ext-0.0.8.2/ext/unf_ext make DESTDIR\= sitearchdir\=./.gem.20250203-69237-u2oi17 sitelibdir\=./.gem.20250203-69237-u2oi17 compiling unf.cc make: *** [unf.o] Error 1 ``` `unf_ext` only checks whether `RbConfig::CONFIG['CXX']` is defined, not that it is `false`: https://github.com/knu/ruby-unf_ext/blob/c72a36d0a5ea9fe3950611b0f289fc68a2…. Questions: 1. Should CXX just be set to `nil`? Or should all C++ extensions be expected to check for `false`? The latter seems surprising to me. 2. Should there be a way to fail the Ruby build if a valid C++ compiler is not found? -- https://bugs.ruby-lang.org/

[ruby-core:122892] [Ruby Bug#21525] Inconsistent execution order for methods with constant blocks

Issue #21525 has been reported by joel(a)drapper.me (Joel Drapper). ---------------------------------------- Bug #21525: Inconsistent execution order for methods with constant blocks https://bugs.ruby-lang.org/issues/21525 * Author: joel(a)drapper.me (Joel Drapper) * Status: Open * ruby -v: ruby 3.4.5 (2025-08-01 revision 07f7832cff) +PRISM [arm64-darwin24] * Backport: 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN ---------------------------------------- If you call a method and pass in a splat of an array with a block argument coerced from calling a method, Ruby maintains the expected execution order and the called method receives a copy of the array prior to modification. In this example, the output is `[1, 2, 3]` since the copy is made before the `bar` method can modify it. ```ruby ARRAY = [1, 2, 3] def bar ARRAY.pop -> {} end def example(*args, &) puts args end example(*ARRAY, &bar) ``` However, when passing a constant, the block coercion itself is able to modify the array. ```ruby ARRAY = [1, 2, 3] module Foo module Bar def self.to_proc ARRAY.pop -> {} end end end def example(*args, &) puts args end example(*ARRAY, &Foo::Bar) ``` Another way to trigger this is to define a `const_missing` method that modifies the array. ```ruby ARRAY = [1, 2, 3] module Foo def self.const_missing(name) ARRAY.pop -> {} end end def example(*args, &) puts args end example(*ARRAY, &Foo::Bar) ``` In both these cases, the output is `[1, 2]` instead of the expected `[1, 2, 3]`. -- https://bugs.ruby-lang.org/

[ruby-core:122343] [Ruby Misc#21385] Namespace: Suggesting a rename

Issue #21385 has been reported by fxn (Xavier Noria). ---------------------------------------- Misc #21385: Namespace: Suggesting a rename https://bugs.ruby-lang.org/issues/21385 * Author: fxn (Xavier Noria) * Status: Open ---------------------------------------- I'd like to suggest a rename of namespaces. The word "namespace" is already taken in Ruby. We say that classes and modules act as or represent. Constant paths nest them in practice. We say that it is a best practice that gems create their own namespace, etc. If the feature goes ahead with this name, the above sentences, well-established in the Ruby community, will start to sound confusing, because that meaning of "namespace" stays. If you look at the index in Matz's book, "namespaces" is indexed in pages 248–250. Title of section 7.5.1 is "Modules as Namespaces". Besides, I have had a few experiences explaining the proposal to people, and quickly realizing they assume this is something like C++ namespaces or Java packages. Then, I have to undo that mental model and start all over saying "forget that mental model". Those are like our constant paths, only more simple and strict. I think it may also be confusing in this sense (though this could be OK if it wasn't for the previous point.) To be constructive: Some alternative names that I have thought about are "isolates", "shields", or "cells". ("sandboxes" is close, but may have security connotations you do not want to suggest.) -- https://bugs.ruby-lang.org/

[ruby-core:122842] [Ruby Feature#21518] Statistical helpers to `Enumerable`
by Amitleshed (Amit Leshed) 31 Jul '25

Issue #21518 has been reported by Amitleshed (Amit Leshed). ---------------------------------------- Feature #21518: Statistical helpers to `Enumerable` https://bugs.ruby-lang.org/issues/21518 * Author: Amitleshed (Amit Leshed) * Status: Open ---------------------------------------- **Summary** I'd like to add two statistical helpers to `Enumerable`: - `Enumerable#average` (arithmetic mean) - `Enumerable#median` Both are small, well-defined operations that many Rubyists re-implement in apps and gems. Providing them in core avoids repeated, ad-hoc code and aligns with `Enumerable#sum`, which Ruby already ships. **Motivation** - These are among the most common “roll-your-own” helpers for arrays/ranges of numbers. - They are conceptually simple, universally useful beyond web/Rails. - Similar to `sum`, they’re primitives for quick data analysis, ETL scripts, CLI tooling, etc. - Including them encourages consistent semantics (what to do with empty sets, mixed numerics, etc.). ## Proposed API & Semantics ```ruby Enumerable#average -> Float or nil Enumerable#median -> Numeric or nil ``` ```ruby [1, 2, 3, 4].average # => 2.5 (1..4).average # => 2.5 [].average # => nil [1, 3, 2].median # => 2 [1, 2, 3, 10].median # => 2.5 (1..6).median # => 3.5 [].median # => nil ``` Ruby implementation ```ruby module Enumerable def average count = 0 total = 0.0 each do |x| raise TypeError, "non-numeric value for average" unless x.is_a?(Numeric) total += x count += 1 end count.zero? ? nil : total / count end def median arr = to_a return nil if arr.empty? arr.each { |x| raise TypeError, "non-numeric value for median" unless x.is_a?(Numeric) } arr.sort! mid = arr.length / 2 arr.length.odd? ? arr[mid] : (arr[mid - 1] + arr[mid]) / 2.0 end end ``` **Upon approval I'm more than willing to implement spec and code in C.** -- https://bugs.ruby-lang.org/

Issue #21522 has been reported by tenderlovemaking (Aaron Patterson). ---------------------------------------- Bug #21522: Accessing outer locals via eval in a Ractor returns false https://bugs.ruby-lang.org/issues/21522 * Author: tenderlovemaking (Aaron Patterson) * Status: Open * Assignee: ractor * ruby -v: ruby 3.5.0dev (2025-07-28T22:17:45Z master f1acf47ca2) +PRISM [arm64-darwin24] * Backport: 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN ---------------------------------------- Normally, if you try to access a local that's been defined outside the scope of the Ractor block, it'll raise an ArgumentError. However, if you try to access the local via `eval` it will return the value `false`. ```ruby foo = Object.new begin Ractor.new { p foo }.value rescue ArgumentError end Ractor.new { p eval("foo") # => false }.value ``` I'm not sure how we fix this, since my guess is that we zero the environment when copying, but I wanted to file the issue so we can track it. -- https://bugs.ruby-lang.org/

[ruby-core:122847] [Ruby Feature#21520] Feature Proposal: Enumerator::Lazy#peek
by nuzair46 (Nuzair Rasheed) 30 Jul '25

30 Jul '25

Issue #21520 has been reported by nuzair46 (Nuzair Rasheed). ---------------------------------------- Feature #21520: Feature Proposal: Enumerator::Lazy#peek https://bugs.ruby-lang.org/issues/21520 * Author: nuzair46 (Nuzair Rasheed) * Status: Open ---------------------------------------- # Abstract Add a #peek method to Enumerator::Lazy that allows observing each element in a lazy enumeration pipeline without modifying or consuming the stream. # Background Ruby provides Enumerator::Lazy for efficient lazy stream processing. However, unlike languages such as Java, it lacks a clean way to inspect intermediate elements during lazy evaluation. Currently, developers must misuse .map for side effects, example: ```rb (1..).lazy.map { |x| puts x; x }.select(&:even?).first(3) ``` This is semantically incorrect and confusing, since .map implies transformation, not observation. # Proposal Introduce Enumerator::Lazy#peek, which yields each item to a block and returns the item unmodified, similar to Object#tap, but in a lazy stream: ```rb (1..).lazy .peek { |x| puts "saw: #{x}" } .select(&:even?) .first(3) ``` This would be equivalent to: ```rb lazy.map { |x| block.call(x); x } ``` but with improved semantic clarity. # Use cases • Debugging lazy enumerators without breaking the chain • Logging or instrumentation in pipelines • Educational / demo use for showing lazy evaluation step-by-step • Cleaner replacement for map { puts x; x } hacks Example: ```rb data = (1..).lazy .peek { |x| puts "got #{x}" } .select(&:even?) .first(5) ``` result: ```rb got 1 got 2 got 3 got 4 got 5 ``` And return [2, 4, 6, 8, 10] # Discussion #peek is a minimal, non-breaking addition that improves clarity and idiomatic usage of Enumerator::Lazy. It avoids abusing .map for observation and is familiar to developers from other languages. #peek is also not needed for other enumerators where .tap or .each can do the job. It mirrors Java’s .stream().peek(...) and makes Ruby’s lazy enumeration more expressive and readable. # See also • [Java Stream.peek](https://docs.oracle.com/javase/8/docs/api/java/util/stream/Str… I would be glad to work on this and make a PR. Thank you. -- https://bugs.ruby-lang.org/
