[ruby-core:116666] [Ruby master Bug#20255] Embedded arrays aren't moved correctly across ractors
by luke-gru (Luke Gruber) 07 Apr '25

Issue #20255 has been reported by luke-gru (Luke Gruber). ---------------------------------------- Bug #20255: Embedded arrays aren't moved correctly across ractors https://bugs.ruby-lang.org/issues/20255 * Author: luke-gru (Luke Gruber) * Status: Open * Priority: Normal * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- `ractor.send(ary, move: true)` works incorrectly because if `ary` is embedded, the new moved object doesn't populate its own embedded space, it uses the MovedObject's embedded space. example: ```ruby r = Ractor.new { inner_ary = receive values = {} values[:equal] = (inner_ary == ["",{},2,3,4,5,6]) values[:string] = inner_ary.to_s values } ary = [String.new,Hash.new,2,3,4,5,6] r.send(ary, move: true) r_values = r.take p r_values[:equal] p r_values[:string] # => false # => "[\"\", {}, 2, 2.0, 21747991570, String, 3]" ``` -- https://bugs.ruby-lang.org/

Issue #19765 has been reported by Ethan (Ethan -). ---------------------------------------- Bug #19765: Ractor.make_shareable ignores self of a proc created from a Method https://bugs.ruby-lang.org/issues/19765 * Author: Ethan (Ethan -) * Status: Open * Priority: Normal * ruby -v: ruby 3.3.0dev (2023-07-12T00:26:03Z master dfe782be17) [x86_64-darwin21] * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- An unshareable receiver of a Proc or a Method will cause make_shareable to error, but this does not happen with a proc from Method#to_proc: ```ruby str = "" a = str.instance_exec { proc { to_s } } Ractor.make_shareable a # => <internal:ractor>:820:in `make_shareable': Proc's self is not shareable: #<Proc:0x00000001064b62c8 (irb):1> (Ractor::IsolationError) b = str.instance_exec { method(:to_s) } Ractor.make_shareable b # => <internal:ractor>:820:in `make_shareable': can not make shareable object for #<Method: String#to_s()> (Ractor::Error) c = str.instance_exec { method(:to_s).to_proc } Ractor.make_shareable c c.call # => "" str[0] = "!" c.call # => "!" ``` Related, maybe: #19372 #19374 Tangential: why does Proc cause Ractor::IsolationError but Method causes Ractor::Error? -- https://bugs.ruby-lang.org/

[ruby-core:118823] [Ruby master Bug#20670] fork deadlocks in child process due to timer thread
by jhawthorn (John Hawthorn) 22 Mar '25

Issue #20670 has been reported by jhawthorn (John Hawthorn). ---------------------------------------- Bug #20670: fork deadlocks in child process due to timer thread https://bugs.ruby-lang.org/issues/20670 * Author: jhawthorn (John Hawthorn) * Status: Open * ruby -v: ruby 3.3.4 (2024-07-09 revision be1089c8ec) [x86_64-linux] * Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- We've been seeing an occasional failure in the Rails CI related to a test which forks and I managed to reduce it to the following reproduction. ``` ruby Thread.new do loop { sleep 0.0001 } end 1000.times do pid = fork{} Process.waitpid(pid) rescue Exception Process.kill(:KILL, pid) raise end ``` This hangs on Ruby 3.3 and HEAD (_fairly_ reliably), but completes always on Ruby 3.2 In a debugger it seems like the timer thread acquires `vm->ractor.sched.lock` in the parent process just as the process is forking. The child process then ends up stuck inside of `thread_sched_atfork` when trying to acquire the same lock. I've opened https://github.com/ruby/ruby/pull/11356 with a fix -- https://bugs.ruby-lang.org/

[ruby-core:114936] [Ruby master Feature#19908] Update to Unicode 15.1

Issue #19908 has been reported by nobu (Nobuyoshi Nakada). ---------------------------------------- Feature #19908: Update to Unicode 15.1 https://bugs.ruby-lang.org/issues/19908 * Author: nobu (Nobuyoshi Nakada) * Status: Assigned * Priority: Normal * Assignee: duerst (Martin Dürst) * Target version: 3.3 ---------------------------------------- The Unicode 15.1 is released. The current enc-unicode.rb seems to fail because of `Indic_Conjunct_break` properties with values. I'm not sure how these properties should be handled well. `/\p{InCB_Liner}/` or `/\p{InCB=Liner}/` as the comments in that file? https://github.com/nobu/ruby/tree/unicode-15.1 is the former. -- 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/
