2025-06-03[ruby/stringio] Support `Ractor#value`Hiroshi SHIBATA
(https://github.com/ruby/stringio/pull/134) from https://bugs.ruby-lang.org/issues/21262 We need to alias `Ractor#value` to `Ractor#take` for old versions of Ruby. --------- https://github.com/ruby/stringio/commit/9954dabd80 Co-authored-by: Koichi Sasada <ko1@atdot.net> Co-authored-by: Sutou Kouhei <kou@clear-code.com>
2025-05-31`Ractor::Port`Koichi Sasada
* Added `Ractor::Port` * `Ractor::Port#receive` (support multi-threads) * `Rcator::Port#close` * `Ractor::Port#closed?` * Added some methods * `Ractor#join` * `Ractor#value` * `Ractor#monitor` * `Ractor#unmonitor` * Removed some methods * `Ractor#take` * `Ractor.yield` * Change the spec * `Racotr.select` You can wait for multiple sequences of messages with `Ractor::Port`. ```ruby ports = 3.times.map{ Ractor::Port.new } ports.map.with_index do |port, ri| Ractor.new port,ri do |port, ri| 3.times{|i| port << "r#{ri}-#{i}"} end end p ports.each{|port| pp 3.times.map{port.receive}} ``` In this example, we use 3 ports, and 3 Ractors send messages to them respectively. We can receive a series of messages from each port. You can use `Ractor#value` to get the last value of a Ractor's block: ```ruby result = Ractor.new do heavy_task() end.value ``` You can wait for the termination of a Ractor with `Ractor#join` like this: ```ruby Ractor.new do some_task() end.join ``` `#value` and `#join` are similar to `Thread#value` and `Thread#join`. To implement `#join`, `Ractor#monitor` (and `Ractor#unmonitor`) is introduced. This commit changes `Ractor.select()` method. It now only accepts ports or Ractors, and returns when a port receives a message or a Ractor terminates. We removes `Ractor.yield` and `Ractor#take` because: * `Ractor::Port` supports most of similar use cases in a simpler manner. * Removing them significantly simplifies the code. We also change the internal thread scheduler code (thread_pthread.c): * During barrier synchronization, we keep the `ractor_sched` lock to avoid deadlocks. This lock is released by `rb_ractor_sched_barrier_end()` which is called at the end of operations that require the barrier. * fix potential deadlock issues by checking interrupts just before setting UBF. https://bugs.ruby-lang.org/issues/21262 Notes: Merged: https://github.com/ruby/ruby/pull/13445
2025-05-13[ruby/stringio] Do not issue warning when calling set_encoding if string is ↵Jeremy Evans
chilled StringIO does not warn for unchilled unfrozen string or for frozen string, so it should not warn for chilled string. https://github.com/ruby/stringio/commit/4ac33b8c70

2025-02-20[ruby/stringio] Make sure shared buffer is copied on mutationAaron Patterson
(https://github.com/ruby/stringio/pull/117) We need to ensure shared buffers are made independent on mutation. Otherwise we could end up mutating unrelated string buffers. --------- https://github.com/ruby/stringio/commit/5101cfb030 Co-authored-by: Aaron Patterson <tenderlove@ruby-lang.org> Co-authored-by: Alan Wu <XrXr@users.noreply.github.com> Co-authored-by: Aaron Patterson <aaron.patterson@gmail.com> Co-authored-by: Sutou Kouhei <kou@cozmixng.org>

[Feature #20205] Followup: https://github.com/ruby/stringio/pull/94 They no longer need to be special cases. If StringIO end up mutating a chilled string, a warning will be emitted. https://github.com/ruby/stringio/commit/dc62d65449

2024-01-18[ruby/stringio] Fix ascii_only? flag in strio_writetomoya ishida
(https://github.com/ruby/stringio/pull/77) Followup of #79 `rb_str_resize()` was changed by https://github.com/ruby/ruby/commit/b0b9f7201acab05c2a3ad92c3043a1f01df3e17f . ```c rb_str_resize(string, shorter) // clear ENC_CODERANGE in some case rb_str_resize(string, longer) // does not clear ENC_CODERANGE anymore ``` ```c // rb_str_resize in string.c if (slen > len && ENC_CODERANGE(str) != ENC_CODERANGE_7BIT) { ENC_CODERANGE_CLEAR(str); } ``` I think this change is based on an assumption that appending null bytes will not change flag `ascii_only?`. `strio_extend()` will make the string longer if needed, and update the flags correctly for appending null bytes. Before `memmove()`, we need to `rb_str_modify()` because updated flags are not updated for `memmove()`. https://github.com/ruby/stringio/commit/b31a538576

(https://github.com/ruby/stringio/pull/67) Fix: https://github.com/ruby/stringio/issues/66 If length is 0, IO#pread don't even try to read the IO, it simply return the buffer untouched if there is one or a new empty buffer otherwise. It also doesn't validate the offset when length is 0. cc @jdelStrother @kou https://github.com/ruby/stringio/commit/37e9279337 Co-authored-by: Jean Boussier <jean.boussier@gmail.com>

2022-05-30[ruby/stringio] Fix handling of chomp with paragraph separatorJeremy Evans
Try to mirror IO behavior, where chomp takes out the entire paragraph separators between entries, but does not chomp a single line separator at the end of the string. Partially Fixes [Bug #18768] https://github.com/ruby/stringio/commit/a83ddbb7f0
2022-05-30[ruby/stringio] Ignore chomp keyword for nil separatorJeremy Evans
nil separator means no separator at all, so nothing should be chomped. Partial fix for Ruby [Bug #18770] https://github.com/ruby/stringio/commit/feaa2ec631
2022-05-30[ruby/stringio] Fix each with multiple character string and chompJeremy Evans
Previously, this could result in an infinite loop. Always update the e pointer in this case, setting w when chomping so the chomped data is not included in the output. Fixes [Bug #18769] https://github.com/ruby/stringio/commit/4bf64d5130
