Issue #20919 has been reported by javanthropus (Jeremy Bopp). ---------------------------------------- Bug #20919: IO#seek does not clear the character buffer in some cases while transcoding https://bugs.ruby-lang.org/issues/20919 * Author: javanthropus (Jeremy Bopp) * Status: Open * ruby -v: ruby 3.4.0dev (2024-11-28T12:38:16Z master 3af1a04741) +PRISM [x86_64-linux] * Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- When transcoding characters, `IO#seek` only clears the internal character buffer if `IO#getc` is called first: ```ruby require 'tempfile' Tempfile.open(encoding: 'utf-8:utf-16le') do |f| f.write('0123456789') f.rewind f.ungetc('a'.encode('utf-16le')) # Character buffer WILL NOT be cleared f.seek(2, :SET) f.getc # => 'a'.encode('utf-16le'); should be '2'.encode('utf-16le') end Tempfile.open(encoding: 'utf-8:utf-16le') do |f| f.write('0123456789') f.rewind # Added a call to #getc here f.getc f.ungetc('a'.encode('utf-16le')) # Character buffer WILL be cleared now f.seek(2, :SET) f.getc # => '2'.encode('utf-16le') end ``` -- https://bugs.ruby-lang.org/

[ruby-core:116555] [Ruby master Feature#20233] pkg-config not working on MSVC

Issue #20233 has been reported by jmarrec (Julien Marrec). ---------------------------------------- Feature #20233: pkg-config not working on MSVC https://bugs.ruby-lang.org/issues/20233 * Author: jmarrec (Julien Marrec) * Status: Open * Priority: Normal ---------------------------------------- The PKG_CONFIG variable is not respected in win32/Makefile.sub Also, need to ideally use the `--msvc-syntax` flag (pkgconf 1.4.0, released 7 years ago, adds it). But mostly, I realized that the `try_ldflags` in `lib/mkmf.rb` actually passes these ldflags as the `opt` parameter to the `link_command` function, and not as `ldflags`. While the UNIX systems are forgiving, the MSVC compiler is not, and because the flags are passed before the `-link`, MSVC complains that it ignores it and therefore cannot find the requested library. -- https://bugs.ruby-lang.org/

[ruby-core:116666] [Ruby master Bug#20255] Embedded arrays aren't moved correctly across ractors

Issue #20255 has been reported by luke-gru (Luke Gruber). ---------------------------------------- Bug #20255: Embedded arrays aren't moved correctly across ractors https://bugs.ruby-lang.org/issues/20255 * Author: luke-gru (Luke Gruber) * Status: Open * Priority: Normal * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- `ractor.send(ary, move: true)` works incorrectly because if `ary` is embedded, the new moved object doesn't populate its own embedded space, it uses the MovedObject's embedded space. example: ```ruby r = Ractor.new { inner_ary = receive values = {} values[:equal] = (inner_ary == ["",{},2,3,4,5,6]) values[:string] = inner_ary.to_s values } ary = [String.new,Hash.new,2,3,4,5,6] r.send(ary, move: true) r_values = r.take p r_values[:equal] p r_values[:string] # => false # => "[\"\", {}, 2, 2.0, 21747991570, String, 3]" ``` -- https://bugs.ruby-lang.org/

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/

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/
