[ruby-core:119074] [Ruby master Bug#20716] Different instance_method behavior in Ruby 2.7 and Ruby 3.x

Issue #20716 has been reported by natton (Tien Truong). ---------------------------------------- Bug #20716: Different instance_method behavior in Ruby 2.7 and Ruby 3.x https://bugs.ruby-lang.org/issues/20716 * Author: natton (Tien Truong) * Status: Open * ruby -v: 3.3.1 * Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- Hi, I am working on upgrading our project from 2.7 to 3.x and found a breaking change in `instance_method` behavior. Here is the code snippet ``` module A def test(*args) super end end module B def test(a) puts a end end B.prepend(A) a = lambda do puts 'lambda' end class C include B end B.instance_method(:test).bind(C.new).call(1) # Ruby 2.7: 1 # Ruby 3.0: 1 # Ruby 3.1: 1 B.module_exec do define_method(:test, a) end B.instance_method(:test).bind(C.new).call # Ruby 2.7: lambda # Ruby 3.0: wrong number of arguments (given 0, expected 1) (ArgumentError) # Ruby 3.1: wrong number of arguments (given 0, expected 1) (ArgumentError) ``` I don't know if this is a bug or a correct intention. My specs: - Ruby manager: rbenv - Tested on - ruby 2.7.4p191 (2021-07-07 revision a21a3b7d23) [x86_64-linux] - ruby 3.0.7p220 (2024-04-23 revision 724a071175) [x86_64-linux] - ruby 3.1.4p223 (2023-03-30 revision 957bb7cb81) [x86_64-linux] - ruby 3.2.3 (2024-01-18 revision 52bb2ac0a6) [x86_64-linux] - ruby 3.3.1 (2024-04-23 revision c56cd86388) [x86_64-linux] -- https://bugs.ruby-lang.org/

[ruby-core:119257] [Ruby master Bug#20755] IO::Buffer#transfer transfers mutable reference to String's memory but not lock ownership

Issue #20755 has been reported by hanazuki (Kasumi Hanazuki). ---------------------------------------- Bug #20755: IO::Buffer#transfer transfers mutable reference to String's memory but not lock ownership https://bugs.ruby-lang.org/issues/20755 * Author: hanazuki (Kasumi Hanazuki) * Status: Open * ruby -v: ruby 3.4.0dev (2024-09-18T02:16:22Z master 4797b0704a) +PRISM [x86_64-linux] * Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- `IO::Buffer.for` with a block yields a mutable IO::Buffer that shares underlying memory with a mutable String. While the block is executed, the String instance is temporarily locked and cannot be modified or frozen. If you call `#transfer` on the yielded IO::Buffer in the block, however, a mutable IO::Buffer can be escaped from the `.for` method. Through this IO::Buffer instance, you can modify the underlying String memory even after the String instance is frozen. ```irb irb(main):001> str = +'a' => "a" irb(main):002> buf = IO::Buffer.for(str) {|b| b.transfer } => #<IO::Buffer 0x00007f244d1ede98+1 EXTERNAL SLICE> ... irb(main):003> str.freeze => "a" irb(main):004> buf.set_string('b') => 1 irb(main):005> str => "b" ``` -- https://bugs.ruby-lang.org/
