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

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/

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/

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

by kddnewton (Kevin Newton) 13 Mar '25

Issue #20340 has been reported by kddnewton (Kevin Newton). ---------------------------------------- Bug #20340: Ractor comments not applying to constant targets https://bugs.ruby-lang.org/issues/20340 * Author: kddnewton (Kevin Newton) * Status: Open * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- In this example: ```ruby C, = { foo: bar } ``` You get: ``` == disasm: #<ISeq:<main>@test.rb:1 (1,0)-(1,17)> 0000 putobject :foo ( 1)[Li] 0002 putself 0003 opt_send_without_block <calldata!mid:bar, argc:0, FCALL|VCALL|ARGS_SIMPLE> 0005 newhash 2 0007 dup 0008 expandarray 1, 0 0011 putspecialobject 3 0013 setconstant :C 0015 leave ``` But there's no difference from: ```ruby # shareable_constant_value: literal C, = { foo: bar } ``` I would have expected: ``` == disasm: #<ISeq:<main>@test.rb:1 (1,0)-(2,16)> 0000 putobject RubyVM::FrozenCore ( 2)[Li] 0002 putobject :foo 0004 putobject RubyVM::FrozenCore 0006 putself 0007 opt_send_without_block <calldata!mid:bar, argc:0, FCALL|VCALL|ARGS_SIMPLE> 0009 putobject "C" 0011 opt_send_without_block <calldata!mid:ensure_shareable, argc:2, ARGS_SIMPLE> 0013 newhash 2 0015 opt_send_without_block <calldata!mid:make_shareable, argc:1, ARGS_SIMPLE> 0017 dup 0018 expandarray 1, 0 0021 putspecialobject 3 0023 setconstant :C 0025 leave ``` Is this omission intentional? For context, I'm building this in prism and I need to know if I should explicitly disable this behavior. -- https://bugs.ruby-lang.org/

[ruby-core:120611] [Ruby master Bug#21026] `def __FILE__.a; end` should be a syntax error
by Earlopain (Earlopain _) 13 Mar '25

13 Mar '25

Issue #21026 has been reported by Earlopain (Earlopain _). ---------------------------------------- Bug #21026: `def __FILE__.a; end` should be a syntax error https://bugs.ruby-lang.org/issues/21026 * Author: Earlopain (Earlopain _) * Status: Open * ruby -v: ruby 3.4.1 (2024-12-25 revision 48d4efcb85) +PRISM [x86_64-linux] * Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN ---------------------------------------- Constants like `__FILE__`, `__LINE__` and `__ENCODING__` are literals and as such you shouldn't be able to defined singleton methods on them. 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/

Issue #21016 has been reported by nobu (Nobuyoshi Nakada). ---------------------------------------- Bug #21016: What should massign with `shareable_constant_value: experimental_everything` freeze? https://bugs.ruby-lang.org/issues/21016 * Author: nobu (Nobuyoshi Nakada) * Status: Open * Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN ---------------------------------------- Derived from #21010. Even with prism: ```ruby # shareable_constant_value: experimental_everything A, = "" p A.frozen? #=> false ``` This `A` should be frozen? Furthermore: ```ruby # shareable_constant_value: experimental_everything A, a = "A", "a" p A.frozen? #=> false p a.frozen? #=> false ``` Should only `A` be frozen but not `a`? Or massign including a constant can freeze everything? -- https://bugs.ruby-lang.org/
