Issue #19407 has been reported by luke-gru (Luke Gruber). ---------------------------------------- Bug #19407: 2 threads taking from current ractor will hang forever https://bugs.ruby-lang.org/issues/19407 * Author: luke-gru (Luke Gruber) * Status: Open * Priority: Normal * Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- In the current implementation of Ractors, it's possible to `take` from the current ractor. This could be useful when co-ordinating threads: ```ruby t = Thread.new do obj = Ractor.current.take p obj # do some work with obj end t0 = Thread.new do obj = Ractor.current.take p obj # do some work with obj end Ractor.yield :go ``` However it hangs forever: ```ruby t = Thread.new do obj = Ractor.current.take p obj end t0 = Thread.new do obj = Ractor.current.take p obj end sleep 0.5 ``` Should "self-take" be disabled, or was it designed to allow it but this is just a bug? -- https://bugs.ruby-lang.org/

Issue #20013 has been reported by jaruga (Jun Aruga). ---------------------------------------- Misc #20013: Travis CI status https://bugs.ruby-lang.org/issues/20013 * Author: jaruga (Jun Aruga) * Status: Open * Priority: Normal ---------------------------------------- I would like to use this ticket to manage our activities to report Travis CI status. Because there is Travis CI status page provided by Travis CI. However, even when the page shows ok, I actually see infra issues. https://www.traviscistatus.com/ I would share my activities and report the Travis CI status on the ticket. The ticket's status is not closed until we stop using Travis CI. The easiest option to fix the Travis infra issue is to email Travis CI support `support _AT_ travis-ci.com`. You can check [this ruby/ruby Travis CI wiki page](https://github.com/ruby/ruby/wiki/CI-Servers#travis-ci) for details. -- https://bugs.ruby-lang.org/

[ruby-core:121136] [Ruby master Bug#21151] IO and StringIO raise FrozenError even for read-only methods
by headius (Charles Nutter) 11 Aug '25

11 Aug '25

Issue #21151 has been reported by headius (Charles Nutter). ---------------------------------------- Bug #21151: IO and StringIO raise FrozenError even for read-only methods https://bugs.ruby-lang.org/issues/21151 * Author: headius (Charles Nutter) * Status: Open * Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN ---------------------------------------- Problem -------- While fixing a small [regression](https://github.com/ruby/stringio/issues/119) from my recent StringIO [fixes](https://github.com/ruby/stringio/issues/116) I discovered that a large number of read-only methods will fail if the StringIO is frozen. A few examples: ``` $ ruby -rstringio -e 's = StringIO.new; p s.lineno; s.freeze; p s.lineno' 0 -e:1:in 'StringIO#lineno': can't modify frozen StringIO: #<StringIO:0x0000000103711ea8> (FrozenError) from -e:1:in '<main>' $ ruby -rstringio -e 's = StringIO.new; p s.closed?; s.freeze; p s.closed?' false -e:1:in 'StringIO#closed?': can't modify frozen StringIO: #<StringIO:0x00000001008c1e68> (FrozenError) from -e:1:in '<main>' $ ruby -rstringio -e 's = StringIO.new; p s.eof?; s.freeze; p s.eof?' true -e:1:in 'StringIO#eof?': can't modify frozen StringIO: #<StringIO:0x000000011c171e80> (FrozenError) from -e:1:in '<main>' $ ruby -rstringio -e 's = StringIO.new; p s.pos; s.freeze; p s.pos' 0 -e:1:in 'StringIO#pos': can't modify frozen StringIO: #<StringIO:0x0000000105551df0> (FrozenError) from -e:1:in '<main>' ``` @kou pointed out that IO also raises for at least `lineno` and suggested I re-open the issue here. I still believe these read-only operations should be allowed on frozen IO or StringIO. Cause in StringIO ----------------- This is because the `StringIO` macro calls `get_strio` which calls `rb_io_taint_check` which calls `rb_check_frozen`. The `StringIO` macro is used in almost every method to access the rb_stringio_t data structure. A list of methods I believe should be operable when the StringIO is frozen (in stringio.c definition order): * string (returns underlying String but does not mutate anything) * lineno * pos * closed?/closed_read?/closed_write? * eof/eof? * sync * pid (a dummy method but it writes nothing) * fileno (dummy) * pread (by definition does not modify state) * isatty/tty? * size/length * external_encoding * internal_encoding In addition, `initialize_copy` probably should not require the original StringIO to be writable: ``` $ ruby -rstringio -e 's = StringIO.new("foo"); s.freeze; p s.dup' -e:1:in 'StringIO#initialize_copy': can't modify frozen StringIO: #<StringIO:0x0000000102eb1df8> (FrozenError) from -e:1:in 'Kernel#initialize_dup' from -e:1:in 'Kernel#dup' from -e:1:in '<main>' ``` The data from the original StringIO is unmodified by `initialize_copy`, other than the reference-counting `ptr->count` (which should not be subject to frozen checks). Cause in IO ----------- The `GetOpenFile` macro calls `RB_IO_POINTER` macro which calls `rb_io_taint_check` which calls `rb_check_frozen`. Methods in IO that should work on a frozen IO include any of the above StringIO that currently raise. For example `lineno` uses `GetOpenFile`, but `fileno` does not and does not raise. There's clearly some inconsistency here we can clean up. Origin ------ I believe most of the StringIO cases are caused by this change from 2011 that added frozen checks to StringIO (the class and the macro): https://github.com/ruby/ruby/commit/d8d9bac5c8b071135e50ad3f21c8a9b6a9c06e54 In IO, this behavior dates way back to 2000 by @matz himself: https://github.com/ruby/ruby/commit/087c83d7ceed6893afff93066937fb570ae4a115 Notes ----- I have started to fix the StringIO cases for JRuby in https://github.com/ruby/stringio/pull/122. I could probably fix the C version of StringIO as well, but I'm a little more unsure about how to fix IO. -- https://bugs.ruby-lang.org/

[ruby-core:111789] [Ruby master Feature#19333] Setting (Fiber Local|Thread Local|Fiber Storage) to nil should delete value in order to avoid memory leaks.
by ioquatix (Samuel Williams) 07 Aug '25

Issue #19333 has been reported by ioquatix (Samuel Williams). ---------------------------------------- Feature #19333: Setting (Fiber Local|Thread Local|Fiber Storage) to nil should delete value in order to avoid memory leaks. https://bugs.ruby-lang.org/issues/19333 * Author: ioquatix (Samuel Williams) * Status: Open * Priority: Normal ---------------------------------------- As it stands, Fiber Locals, Thread Locals and Fiber Storage have no way of deleting key-value associations. ```ruby 100.times do |i| name = :"variable-#{i}" Thread.current[name] = 10 end ``` Because of this, dynamically generated associations can leak over time. This is worse for things like Threads that might be pooled (or maybe an argument against user-space pooling). In any case, having a way to delete those associations would allow application code to at least delete the associations when they no longer make sense. I propose that assigning `nil` to "locals" or "storage" should effectively delete them. e.g. ```ruby 100.times do |i| name = :"variable-#{i}" Thread.current[name] = 10 Thread.current[name] = nil # delete association end ``` A more invasive alternative would be to define new interfaces like `Thread::Local`, `Fiber::Local` and `Fiber::Storage::Local` (or something) which correctly clean up on GC. -- https://bugs.ruby-lang.org/

[ruby-core:122817] [Ruby Bug#21517] Behaviour of StringIO#readpartial with multibyte differs from IO#readpartial

Issue #21517 has been reported by herwin (Herwin W). ---------------------------------------- Bug #21517: Behaviour of StringIO#readpartial with multibyte differs from IO#readpartial https://bugs.ruby-lang.org/issues/21517 * Author: herwin (Herwin W) * Status: Open * ruby -v: ruby 3.4.5 (2025-07-16 revision 20cda200d3) +PRISM [x86_64-linux] (+ others) * Backport: 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN ---------------------------------------- The specs for `IO#readpartial` have the following test (https://github.com/ruby/spec/blob/ed254bae321221f5cd24280beb37e5bddaff6bb6/…) ```ruby before :each do @rd, @wr = IO.pipe @rd.binmode @wr.binmode end it "reads after ungetc with multibyte characters in the buffer" do @wr.write("∂φ/∂x = gaîté") c = @rd.getc @rd.ungetc(c) @rd.readpartial(3).should == "\xE2\x88\x82" @rd.readpartial(3).should == "\xCF\x86/" end ``` This behaviour is different in `StringIO#readpartial`. If I add this as a spec: ```ruby it "reads after ungetc with multibyte characters in the buffer" do @string = StringIO.new(+"∂φ/∂x = gaîté") c = @string.getc @string.ungetc(c) @string.readpartial(3).should == "\xE2\x88\x82" @string.readpartial(3).should == "\xCF\x86/" end ``` it fails with every supported Ruby version, and even with 3.5-dev of today, with the message `Expected "\xE2\x88\x82" == "∂"` The `getc` + `ungetc` can be removed, but this does not change the behaviour. -- https://bugs.ruby-lang.org/

[ruby-core:122892] [Ruby Bug#21525] Inconsistent execution order for methods with constant blocks
by joel＠drapper.me (Joel Drapper) 01 Aug '25

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/

Following is my observation: There are 24 threads and all are doing the thread local memory cleanup as part of garbage collection process. Thread 23 especially is reporting sigsegv during the GC process. Thread 1 is SIGABORT due to the corruption at Thread 23 root [ / ]# ruby --version ruby 2.7.3p183 (2021-04-05 revision 6847ee089d) [x86_64-linux] root [ / ]# gem --version 3.1.6 -- https://bugs.ruby-lang.org/
