Description

The next dev meeting

Date: 2022/03/17 13:00-17:00 (JST)
Log: https://github.com/ruby/dev-meeting-log/blob/master/DevMeeting-2022-03-17.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 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 2022/03/14. 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.

  • [Feature #18598] Add String#bytesplice
    • I withdrew the proposal of String#bytesplice in #13110 because it may cause problems if the specified offset does not land on character boundary.
      But how about to raise IndexError in such cases?
# encoding: utf-8

s = "あいうえおかきくけこ"
s.bytesplice(9, 6, "xx")
p s #=> "あいうxxかきくけこ"
s.bytesplice(2, 3, "x") #=> offset 2 does not land on character boundary (IndexError)
s.bytesplice(3, 4, "x") #=> offset 7 does not land on character boundary (IndexError)

  • [Feature #18576] Rename ASCII-8BIT encoding to BINARY
    • The patch is ready.
    • I'd like to make the change for 3.2.0-preview1, so that we can get early feedback and if it's negative revert before final release.
    • Matz last statement is ambiguous, does it means OK for 3.2.0-preview1?
    • There's an open question on wether C API should alias *ascii8bit* functions too.

  • [Feature #18589] Finer-grained constant invalidation
    • We want to trade a very small memory increase for much better constant cache invalidation.
    • This will allow relying on more stable constant caches for better code specialization in JITs.
    • This can also help speed up initial boot times since caches are currently invalidated each time a class is created.
    • Because of APIs like Object#extend, ActiveRecord::Relation#extending, and autoload, constant caches get busted far more often than they should in production applications, and has a measurable impact on request speed.

  • [Feature #18615] Use -Werror=implicit-function-declaration by default for building C extensions (eregon)
    • OK to do it? It seems an obvious gain and will avoid many confusing errors which happen too late and instead make them clear and early.

Updated by znz (Kazuhiro NISHIYAMA) over 2 years ago

  • [Feature #18563] Add "graphemes" and "each_grapheme" aliases (znz)
    • Some languages already use graphemes.

  • [Feature #18566] Merge io-wait gem into core IO class. (byroot)
    • It's very small and any non-trivial IO code will require it.
    • Merge io-wait into io.c for Ruby 3.2
    • Remove io-wait as a dependency of all gems maintained by ruby-core (e.g. net-protocol).
    • Publish a new io-wait version that is simply an empty gem.
    • Add a lib/io/wait.rb stub, with eventually a verbose deprecation warning.
    • It was suggested to do the same with io-nonblock.

  • [Bug #18620] Not possible to partially curry lambda or proc's call method (jeremyevans0)
    • Should we make changes to allow this to work? It complicates the internals, and the benefits seem minimal.
    • If we do decide to make this change, I've prepared a patch, but the implementation is suboptimal.
  • [Feature #15357] Proc#parameters returns incomplete type information (jeremyevans0)
    • Last discussed at the March 2020 developer meeting, but no decision was made.
    • I still think it makes sense to consider a lambda keyword argument for Proc#parameters.
  • [Feature #12655] Accessing the method visibility (jeremyevans0)
    • This issue discusses many things that have been discussed previously in other issues.
    • I want to focus on one additional method: Module#undefined_instance_methods
    • We don't currently offer a way to see which methods are undefined in a module.
    • Is this worth adding? The use case I know of is it would allow significantly simpler implementation of the looksee gem.
  • [Bug #11063] Special singleton class should return true for singleton_class? test (jeremyevans0)
    • I don't think it is worth changing the existing behavior.
    • Can this be rejected?

  • [Bug #18632] Struct.new wrongly treats a positional Hash as keyword arguments (eregon)
    • Some C functions incorrectly treat a positional Hash as keyword arguments, e.g. Struct.new and Struct#initialize.
    • This is inconsistent with the separation of positional and keyword arguments in Ruby 3
    • Jeremy proposed to audit and fix them
  • [Bug #18625] ruby2_keywords does not unmark the hash if the receiving method has a *rest parameter (eregon)
    • This seems a clear inconsistency, and it hurts for 3 reasons:
    • Can cause issues when migrating to other forms of delegation
    • Makes the ruby2_keywords semantics confusing/inconsistent/more complex
    • May force other Ruby implementations to replicate this bug if not fixed
    • I believe we should fix it now. Fixing it later would cause issues when migrating to (*args, **kwargs) or (...).

Updated by Eregon (Benoit Daloze) over 2 years ago

  • [Bug #18633] proc { |a, **kw| a } autosplats and treats empty kwargs specially (eregon)
    • Intended or bug? Should we fix it?

I am in wrong time zone. if you have time, can you check these?

  • [Feature #18630] Introduce general IO#timeout and IO#timeout=for all (non-)blocking operations.
    • PR is functional. Can we merge it?
  • [Bug #18465] Make IO#write atomic.
    • When IO is set to sync mode, operations like puts should be atomic.
    • Reduce number of times lock is acquired and released per operation.
    • Improves consistency of output to sync IO when used by multiple threads.
    • PR is functional. Can we merge it?
