The next dev meeting

Date: 2024/12/12 13:00-17:00 (JST)
Log: TBD

• Dev meeting IS NOT a decision-making place. All decisions should be done at the bug tracker.
• Dev meeting is a place we can ask Matz, nobu, nurse and other developers directly.
• Matz is a very busy person. Take this opportunity to ask him. If you can not attend, other attendees can ask instead of you (if attendees can understand your issue).
• We will write a record of the discussion in the file or to each ticket in English.
• All activities are best-effort (keep in mind that most of us are volunteer developers).
• The date, time and place of the meeting are scheduled according to when/where we can reserve Matz's time.
• DO NOT discuss then on this ticket, please.

Call for agenda items

If you have a ticket that you want matz and committers to discuss, please post it into this ticket in the following format:

* [Ticket ref] Ticket title (your name)
  * Comment (A summary of the ticket, why you put this ticket here, what point should be discussed, etc.)

Example:

* [Feature #14609] `Kernel#p` without args shows the receiver (ko1)
  * I feel this feature is very useful and some people say :+1: so let discuss this feature.

• It is recommended to add a comment by 2024/12/09. We hold a preparatory meeting to create an agenda a few days before the dev-meeting.
• The format is strict. We'll use this script to automatically create an markdown-style agenda. We may ignore a comment that does not follow the format.
• Your comment is mandatory. We cannot read all discussion of the ticket in a limited time. We appreciate it if you could write a short summary and update from a previous discussion.

[byroot (Jean Boussier)]

• [Feature #20878] A new C API to create a String by adopting a pointer (byroot)
  • Would be useful for many extensions.
  • Allow to efficiently work with a raw, malloced buffer, and then turn it into a Ruby string without copying it.
  • The pointer is adopted as soon as the function is called, if the function fails the pointer is freed immediately.
  • Proposed implementation: https://github.com/ruby/ruby/pull/12143
  • Current name is rb_enc_str_adopt, but rb_enc_str_move could be make sense too.

[tenderlovemaking (Aaron Patterson)]

• [Feature #20861] Add an environment variable so we can change the thread quantum
  • It maintains the default quantum but allows applications to experiment with different quantums
  • Lower quantums can help improve performance for applications with mixed IO / CPU workloads
  • The best quantum depends on the application load, so having a configuration option would be nice
  • We discussed at RubyConf and the feature seems fine but the name maybe not good enough. What is an appropriate name?
