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:122797] [Ruby Feature#21515] Add `&return` as sugar for `x=my_calculation; return x if x`
by nhorton (Noah Horton) 06 Aug '25

Issue #21515 has been reported by nhorton (Noah Horton). ---------------------------------------- Feature #21515: Add `&return` as sugar for `x=my_calculation; return x if x` https://bugs.ruby-lang.org/issues/21515 * Author: nhorton (Noah Horton) * Status: Open ---------------------------------------- Let me preface this by saying I have no marriage to the exact keyword name of `&return`. # Problem It is very common to have an early return in code where you get some initial value and return it if it is non-null. i.e. ``` return my_calculation(input_a, input_b) if my_calculation(input_a, input_b) ``` That form on its own is verbose and one where you need to look at it for a moment to confirm it is the same code on either side of the if. If `my_calculation` is non-trivial at all, it normally gets turned into something with a variable: ``` my_calc = my_calculation(input_a, input_b) return my_calc if my_calc ``` That is now two lines. The worse scenario, however, is if the user did not bother doing that and my_calculation turned out to be expensive (and they did not know it). # Proposal I propose a syntax of `&return my_calculation(input_a, input_b)` where it will evaluate the argument and return it as the result of the method if it is non-nil, otherwise it will continue on. # Alternatives ## Do Nothing There is no way to work around this with rolling your own methods. You can't make a `returnif` method or something yourself since you can't do a return in the caller's scope. ## Different Name The best other name I saw were permutations of `returnif`. The biggest issue I see is the similarity of the following two statements: ``` return if foo returnif foo ``` Those are obviously very, very different statements, but are somewhat similar. However, things like this are common, and the code is still quite distinct on those, so I think it is acceptable. Ultimately, this feels so similar to the safe navigator that using `&` in this context feels appropriate. Thank you all for your consideration. -- https://bugs.ruby-lang.org/

[ruby-core:122910] [Ruby Bug#21530] Is IO#eof? supposed to always block and read?
by tenderlovemaking (Aaron Patterson) 05 Aug '25

Issue #21530 has been reported by tenderlovemaking (Aaron Patterson). ---------------------------------------- Bug #21530: Is IO#eof? supposed to always block and read? https://bugs.ruby-lang.org/issues/21530 * Author: tenderlovemaking (Aaron Patterson) * Status: Open * Backport: 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN ---------------------------------------- I'm not sure whether or not this is expected behavior, but it seems like eof? blocks when called on $stdin. For example: ```ruby if (str = $stdin.gets) $stderr.puts "read #{str}" end if $stdin.eof? # this call waits for input $stderr.puts "stdin is eof" end ``` I think this is kind of odd behavior because if you input a string but _do not_ input a newline, then hit ^D twice, `$stdin` should be at EOF, but `eof?` will block and wait for input. If you hit ^D a third time, $stdin will be EOF, but if you input a different character it will not be EOF. Compare this C program: ```c #include <stdio.h> #include <stdlib.h> #define BUF_SIZE 4096 int main(int argc, char *argv[]) { char buf[BUF_SIZE]; if (fgets(buf, BUF_SIZE, stdin)) { fprintf(stderr, "read %s\n", buf); } if (feof(stdin)) { // Does not block fprintf(stderr, "stdin is EOF\n"); } } ``` If you hit ^D twice with this C program, `feof` will return true for `stdin`. I would have expected the Ruby program and the C program to behave similarly, but they don't. Is this expected? The documentation indeed says that `eof?` will read, but shouldn't the IO be at EOF after the second ^D? Thank you. -- 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

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/

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/
