Description

The next dev meeting

Date: 2024/11/07 13:00-17:00 (JST)
Log: https://github.com/ruby/dev-meeting-log/blob/master/2024/DevMeeting-2024-11-07.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 2024/11/04. 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 #20794] Expose information about the currently running GC Module (@eightbitraptor (Matt V-H))
    • This adds a dynamic component to RUBY_DESCRIPTION, when a modular GC is loaded. Is this acceptable?
    • This adds a method GC.active_gc_name
      • Is the name OK?
      • Are the semantics OK? (nil unless a GC module is actively being used).

  • [Feature #20860] Merge Optional Experimental Feature MMTk into Ruby
    • We are proposing to merge MMTk into the ruby/mmtk repository, which will be mirrored into ruby/ruby.
    • This implementation uses the GC API (introduced in [Feature #20470]).
    • Supports the NoGC and mark-sweep algorithms.
    • We do not ever anticipate replacing Ruby's default GC with MMTk but instead offer it as an alternative implementation.
    • We have our roadmap proposed in the ticket, which includes supporting generations, improving parallelism, and support moving, faster algorithms such as Immix.

  • [Feature #20818] Allow passing a block to Hash#store to update current value (furunkel)
    • currently, to update a value in a hash we have to call #[] followed by #[]=
      • this calls #hash twice (on key), and requires two lookups; this also happens for shortcuts such as h[k] += c
    • the problem could be solved by introducing a block form for Hash#store (Hash#update is already taken)
      • the block is called with the current value or the default value if the key does not exist; return value = new value
      • inverse of Hash#fetch, which also can take block
    • h[k] = some_method(h[k]) could be written as h.store(k) { some_method(_1) }, more efficient and more elegant in some cases (e.g., if k is complex, no repetition)
    • exists in other languages: e.g., Map#computeIfAbsent|Present (Java) or and_modify (Rust)
    • existing implementation: GH PR#11956

  • [Feature #20770] (Re)Introduce pipe operator (AlexandreMagro)
    • Initially proposed as syntactic sugar for .then, and later refined after discussion to work as a statement separator (like ;) with a variable carrying the LHS expression result to the RHS in #note-34.
    • This approach aligns with how pipes work in other languages, adapted for Ruby.
    • Improves readability by transforming p(q(r)) into a more natural r |> q |> p, matching how we think.

Do you mean r |> q(_) |> p(_)?

Updated by ioquatix (Samuel Williams) 16 days ago · Edited

  • [Bug #20863] zlib.c calls rb_str_set_len and rb_str_modify_expand(and others) without holding the GVL (ioquatix)
  • [Feature #20877] Introduce (public) debug assertion for holding the GVL (ioquatix)
    • Is the PR (https://github.com/ruby/ruby/pull/11975 - ignore the changes to zlib.c) to introduce these checks internally acceptable?
    • Can we add more checks to other functions in CRuby?
    • Can we introduce a public macro so that other native extensions can also implement this check?
      • Can we agree on a name for this macro and any related public functions?
  • [Feature #20876] Introduce Fiber::Scheduler#blocking_operation_wait to avoid stalling the event loop (ioquatix)
    • Is the proposed scheduler hook acceptable?
  • [Feature #20864] Allow Kernel#warn to accept **options and pass these to Warning.warn (ioquatix)
    • Is such an interface acceptable?
    • If we introduce the updated interface, do we need to provide C function too?

Updated by byroot (Jean Boussier) 15 days ago

  • [Bug #20869] IO buffer handling is inconsistent when seeking (byroot)
    • The ticket show multiple weirdness around IO#ungetbyte / IO#ungetc and #IO#seek.
    • This is very clearly a bug, but what the right behavior should be isn't very clear. Clarification would be welcome.
