[ruby-core:122910] [Ruby Bug#21530] Is IO#eof? supposed to always block and read?

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
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/

[ruby-core:122883] [Ruby Bug#21522] Accessing outer locals via eval in a Ractor returns false
by tenderlovemaking (Aaron Patterson) 31 Jul '25

Issue #21522 has been reported by tenderlovemaking (Aaron Patterson). ---------------------------------------- Bug #21522: Accessing outer locals via eval in a Ractor returns false https://bugs.ruby-lang.org/issues/21522 * Author: tenderlovemaking (Aaron Patterson) * Status: Open * Assignee: ractor * ruby -v: ruby 3.5.0dev (2025-07-28T22:17:45Z master f1acf47ca2) +PRISM [arm64-darwin24] * Backport: 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN ---------------------------------------- Normally, if you try to access a local that's been defined outside the scope of the Ractor block, it'll raise an ArgumentError. However, if you try to access the local via `eval` it will return the value `false`. ```ruby foo = Object.new begin Ractor.new { p foo }.value rescue ArgumentError end Ractor.new { p eval("foo") # => false }.value ``` I'm not sure how we fix this, since my guess is that we zero the environment when copying, but I wanted to file the issue so we can track it. -- https://bugs.ruby-lang.org/

[ruby-core:122868] [Ruby Bug#21521] Don't require dummy makefile in `extconf.rb`
by ioquatix (Samuel Williams) 28 Jul '25

28 Jul '25

Issue #21521 has been reported by ioquatix (Samuel Williams). ---------------------------------------- Bug #21521: Don't require dummy makefile in `extconf.rb` https://bugs.ruby-lang.org/issues/21521 * Author: ioquatix (Samuel Williams) * Status: Open * Backport: 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN ---------------------------------------- On some platforms, no native extensions should be created. Due to limitations in `mkmf`, it is typical to create a dummy makefile that does nothing: https://github.com/search?q=File.write+Makefile+path%3A**%2Fextconf.rb&type… This seems like a bad pattern, I think it would be preferable to just do: ``` # extconf.rb return if build_not_required? require "mkmf" ... create_makefile ``` -- https://bugs.ruby-lang.org/

[ruby-core:120617] [Ruby master Feature#21028] Method for finding why an object isn't Ractor shareable
by tenderlovemaking (Aaron Patterson) 26 Jul '25

26 Jul '25

Issue #21028 has been reported by tenderlovemaking (Aaron Patterson). ---------------------------------------- Feature #21028: Method for finding why an object isn't Ractor shareable https://bugs.ruby-lang.org/issues/21028 * Author: tenderlovemaking (Aaron Patterson) * Status: Open ---------------------------------------- `Ractor.shareable?` is easy to use, but if it returns false I would like to be able to figure out what object is causing the data structure to _not_ be Ractor shareable. The context is that I'm trying to make some complex data structures in Rails deeply frozen. If they are deeply frozen they _should_ be Ractor shareable, but `Ractor.shareable?` is returning `false` and it's hard for me to figure out _why_. I would like a method that would either return all unshareable references, or a method that takes a block and unshareable references are yielded to the block. A method like `Ractor.unshareable_references?` or maybe `Ractor.shareable?(obj) { |not_shareable_obj| }` would be very helpful for discovering why an object is not shareable. Thanks! -- https://bugs.ruby-lang.org/
