The next dev meeting

Date: 2021/09/16 13:00-17:00
Place/Sign-up/Agenda/Log: https://github.com/ruby/dev-meeting-log/blob/master/DevelopersMeeting20210916Japan.md

• 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 log about the discussion to a 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 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 2021/09/13. 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.

• Related to Misc #14770: [META] DevelopersMeeting added

[zverok (Victor Shepelev)]

• [Feature #18136] take_while_after (or take_upto)
  • I have proposed it once a long time ago, but those examples were convoluted; now I came with clearer ones and explanations of the usefulness.
  • I am ready to work on the PR, if accepted.

[kou (Kouhei Sutou)]

• [Feature #18143] Add a new method to change GC.stress only in the given block such as GC.with_stress(flag) {...} (kou)
  • This feature is generally useful for debugging GC related problems and writing tests for them.
  • We don't need to implement the same feature multiple times if GC provides the feature by default.

[shyouhei (Shyouhei Urabe)]

• Ruby 2.6.8's fileutils is out of sync of its gem https://github.com/ruby/fileutils/issues/59 (@shyouhei (Shyouhei Urabe))
  • @headius (Charles Nutter) found this glitch. It seems to be due to https://bugs.ruby-lang.org/issues/16979.
  • Given the diff is a bug fix, should the gem also be fixed?

[byroot (Jean Boussier)]

• [Feature #18148] Marshal.load freeze option
  • Useful to deserialize static data that is meant to stay in memory.
  • Useful for in-memory caches.
  • JSON,Psych and MessagePack all added a similar option in the last couple years.
• [Bug #18141] Marshal load with proc yield strings before they are fully initialized
  • UTF-8 strings are yielded as ASCII-8BIT because their encoding isn't set yet.
  • If the proc freeze the string, Marshal.load raises a FrozenError

[hsbt (Hiroshi SHIBATA)]

• How about these proposals? Does anyone have an objections for them?
  • [Feature #17297]: Feature: Introduce Pathname.mktmpdir
  • [Feature #17296]: Feature: Pathname#chmod use FileUtils.chmod instead of File
  • [Feature #17294]: Feature: Allow method chaining with Pathname#mkpath Pathname#rmtree
  • [Feature #17295]: Feature: Create a directory and file with Pathname#touch

[hsbt (Hiroshi SHIBATA)]

• Organization level funding configuration for Ruby account of GitHub
  • https://efcl.info/2021/09/04/github-meta-repository/
  • to Matz: How about this?

[duerst (Martin Dürst)]

• [Feature #18159] Integrate functionality of dead_end gem into Ruby (duerst)
  • It would be very helpful for beginners

[jeremyevans0 (Jeremy Evans)]

• [Bug #15027] When Struct#each method is overriden Struct#select and Struct#to_a use wrong collections (jeremyevans0)
  • Do we want methods like Struct#select to internally call #each (at least if #each is overridden)? (I'm against making such a change)
• [Bug #11182] Refinement with alias causes strange behavior (jeremyevans0)
  • I think the current behavior of alias is expected and is not a bug. Can this be closed?
• [Bug #17568] Thread.handle_interrupt is per-Thread but should probably be per-Fiber (jeremyevans0)
  • Do we want to make Thread.handle_interrupt a per-Fiber setting?
  • Seems confusing to me to do so, considering it's a method defined on Thread.
• [Bug #17429] Prohibit include/prepend in refinement modules (jeremyevans0)
  • @shugo (Shugo Maeda) has a patch to deprecate Refinement prepend/include, and add Refinement#import.
  • Is it OK to merge @shugo's patch?
• [Bug #17048] Calling initialize_copy on live modules leads to crashes (jeremyevans0)
  • It's still possible to hang the interpreter by calling Module#initialize_copy directly.
  • Do we want to make changes in this area, or is OK to accept the current behavior and close this issue?

Please create a ticket. Alternatively, you can propose another good way to create an agenda markdown automatically.
