Issue #21092 has been reported by jeremyd2019 (Jeremy Drake). ---------------------------------------- Bug #21092: error building ruby 3.4.1 on cygwin https://bugs.ruby-lang.org/issues/21092 * Author: jeremyd2019 (Jeremy Drake) * Status: Open * Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN ---------------------------------------- While building from the release tarball ruby-3.4.1.tar.xz (also confirmed in snapshot-master.tar.gz from Jan 27, 2025), I get the following error: ../ruby-3.4.1/ext/extmk.rb:279:in 'Array#-': no implicit conversion of nil into Array (TypeError) from ../ruby-3.4.1/ext/extmk.rb:279:in 'Object#extmake' from ../ruby-3.4.1/ext/extmk.rb:659:in 'block in <main>' from ../ruby-3.4.1/ext/extmk.rb:653:in 'Array#each' from ../ruby-3.4.1/ext/extmk.rb:653:in '<main>' I have tracked this down to happening when an ext writes a dummy makefile. In this case, that ext is .bundle/gems/syslog-0.2.0. See https://github.com/ruby/syslog/pull/16 for fixing why it is writing a dummy makefile to begin with, but still, it seems like extmk.rb should handle this case gracefully rather than breaking the build. -- https://bugs.ruby-lang.org/

[ruby-core:120459] [Ruby master Bug#20996] Embed Failure

Issue #20996 has been reported by cfis (Charlie Savage). ---------------------------------------- Bug #20996: Embed Failure https://bugs.ruby-lang.org/issues/20996 * Author: cfis (Charlie Savage) * Status: Open * ruby -v: ruby 3.4.1 (2024-12-25 revision 48d4efcb85) +PRISM * Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN ---------------------------------------- Rice embeds Ruby in order to run its tests. This code has worked across multiple Ruby versions (current tests are 3.1, 3.2, 3.3 and 3.4 but previously tests were run on 3.0 and 2.x). However, it fails on 3.4 in different ways on different operating systems. The code is here - https://github.com/ruby-rice/rice/blob/master/test/embed_ruby.cpp#L10. ``` c int argc = 0; char* argv = nullptr; char** pArgv = &argv; // ruby_sysinit(&argc, &pArgv); ruby_init(); ruby_init_loadpath(); #if RUBY_API_VERSION_MAJOR == 3 && RUBY_API_VERSION_MINOR >= 1 // Force the prelude / builtins const char* opts[] = { "ruby", "-e;" }; ruby_options(2, (char**)opts); #endif ``` The test suite is here: https://github.com/ruby-rice/rice/actions/runs/12534403540/job/35007888873 With Ruby 3.4 on Fedora this fails with the following stack trace: ```c libruby.so.3.4!str_gsub(int

It already doesn't seem to actually do anything: ```rb def __FILE__.a end __FILE__.a #=> undefined method 'a' for an instance of String (NoMethodError) ``` Wrapping it in brackets correctly reports a syntax error: ```rb code.rb:1: syntax error found (SyntaxError) > 1 | def (__FILE__).a | ^~~~~~~~ cannot define singleton method for literals 2 | end ``` The behavior is consistent between prism and parse.y `__ENCODING__` is frozen and so will result in a runtime error. Same for `__LINE__`, and also `__FILE__` with frozen string literals. -- https://bugs.ruby-lang.org/

[ruby-core:115512] [Ruby master Bug#20025] Parsing identifiers/constants is case-folding dependent
by kddnewton (Kevin Newton) 13 Mar '25

13 Mar '25

Issue #20025 has been reported by kddnewton (Kevin Newton). ---------------------------------------- Bug #20025: Parsing identifiers/constants is case-folding dependent https://bugs.ruby-lang.org/issues/20025 * Author: kddnewton (Kevin Newton) * Status: Open * Priority: Normal * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- When CRuby parses identifiers, it is encoding-dependent. Once the identifier is found, it determines if it starts with a uppercase or lowercase codepoint. This determines if the identifier is a constant or not. The function is charge of this is `rb_sym_constant_char_p`. For non-unicode encodings where the leading byte has the top-bit set, this relies on onigmo's `mbc_case_fold` to determine if it is a constant or not (as opposed to `is_code_ctype`). This works for almost every single codepoint in every encoding, but has one very weird edge case. In the Windows-1253 encoding for the 0xB5 byte, it's the micro sign. The micro sign, when case folded, becomes the uppercase mu character, and then the lowercase mu character, or 0xEC. This means that even though 0xB5 reports itself as being a lowercase codepoint, it gets parsed as a constant. This example might make this more clear: ``` ruby class Context < BasicObject def method_missing(name, *) = :identifier def self.const_missing(name) = :constant end encoding = Encoding::Windows_1253 character = 0xB5.chr(encoding) source = "# encoding: #{encoding.name}\n#{character}\n" result = Context.new.instance_eval(source) puts "#{encoding.name} encoding of 0x#{character.ord.to_s(16).upcase}" puts " [[:alpha:]] => #{character.match?(/[[:alpha:]]/)}" puts " [[:alnum:]] => #{character.match?(/[[:alnum:]]/)}" puts " [[:upper:]] => #{character.match?(/[[:upper:]]/)}" puts " [[:lower:]] => #{character.match?(/[[:lower:]]/)}" puts " parsed as #{result}" ``` this results in the output of: ``` Windows-1253 encoding of 0xB5 [[:alpha:]] => true [[:alnum:]] => true [[:upper:]] => false [[:lower:]] => true parsed as constant ``` To be clear, I don't think the case-folding is incorrect here (and @duerst confirms that it is correct). I believe instead that it is incorrect to use case-folding here to determine if a codepoint is uppercase or not. Note that this only impacts this one codepoint in this one encoding, so I don't believe this is actually a large-scale problem. But I found it surprising, and think we should change it. -- https://bugs.ruby-lang.org/
