Description

The next dev meeting

Date: 2020/08/26 13:00-17:00
Place/Sign-up/Agenda/Log: https://github.com/ruby/dev-meeting-log/blob/master/DevelopersMeeting20200826Japan.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.
  • Comment deadline: 2020/08/19 (one week before the 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.

Please note that it may not be possible to go though all topics that are raised in this agenda because we will discuss 2.8/3.0 release schedule. (Perhaps, we will prioritize the topics related to 2.8/3.0, such as Ractor.) Thanks.

Updated by marcandre (Marc-Andre Lafortune) 2 months ago

  • [Feature #16989] Sets need ♥️, aka the "Set Program" (marcandre)
    • Bring Set into core
    • Insure interoperability with Array (e.g so array & set works and is efficient)
    • Shorthand syntax for static frozen sets of string/symbols (e.g. %ws{hello world})

Updated by jeremyevans0 (Jeremy Evans) 2 months ago

  • [Feature #17055] Allow suppressing uninitialized instance variable and method redefined verbose mode warnings (jeremyevans0)
    • This keeps the default behavior the same as before, but allows opt-in to supress the warnings.
    • This allows for high-performance code (uninitialized instance variables) and safe code (redefining methods without removing in multi-thread environments) to work without issuing warnings in verbose mode.
    • Is it OK to commit the patch?

Updated by Eregon (Benoit Daloze) about 2 months ago

  • [Feature #14844] Future of RubyVM::AST? (eregon)
    • Other Ruby implementations need to be able to implement it too given more and more gems use it. Where do we move it?
  • [Feature #15752] A dedicated module for experimental features (eregon)
    • Create ExperimentalFeatures and move things there or RubyVM exists on all Ruby implementations? Please choose.

Updated by Dan0042 (Daniel DeLorme) about 2 months ago

  • [Bug #17017] Range#max & Range#minmax incorrectly use Float end as max (dan0042)
    • (1..3.1).max has resulted in 3.1 since ruby 1.9 and has now been "fixed" to return 3. Matz, please confirm?

Updated by byroot (Jean Boussier) about 2 months ago

  • [Feature #17103] Add a :since option to ObjectSpace.dump_all (byroot)
    • On large heap, dump_all can take over a minute and generate huge (6+GiB) files.
    • since: 42, means only objects matching generation && generation >= 42 would be dumped.
    • Sometimes you are only interested in objects allocated past a certain point, this make that use case much faster and efficient.

Updated by Eregon (Benoit Daloze) about 2 months ago

  • [Feature #17104] Do not freeze interpolated strings when using frozen-string-literal (eregon)
    • It seems many people agree there is no point to freeze interpolated strings.
    • Interpolated strings are not "simple literals" (just like 1 + 2 is not a literal) and they involve mutation anyway, it seems of very little value to freeze, and it's inconvenient.
    • bughit (bug hit): The reasons are, it will reduce allocations, be more logical, less surprising and produce simpler code (when a mutable string is needed and you don't want extra allocations)

Updated by byroot (Jean Boussier) about 2 months ago

  • [Feature #13381] Expose rb_fstring and its family to C extensions
    • It's only missing a decision on the names. Could this be discussed again?

Updated by Eregon (Benoit Daloze) about 2 months ago

  • [Bug #17105] A single return can return to two different places in a proc inside a lambda inside a method (eregon)
    • Is current implementation correct? Should it not be a LocalJumpError if the surrounding lambda is no longer on stack?

Updated by znz (Kazuhiro NISHIYAMA) about 1 month ago

  • [Feature #17125] Remove Thread.exclusive (znz)
    • Thread.exclusive is deprecated since 2.3.

Updated by mame (Yusuke Endoh) about 1 month ago

  • [Feature #17122] Add category to Warning#warn (mame)
    • I'd like to hear opinions from the committers

Updated by mrkn (Kenta Murata) about 1 month ago

  • [Feature #14723] python's buffer protocol clone (mrkn)
    • I renamed buffer to memory_view.
      • This name is already used in Python for the Python object wrapper of PyBuffer.
    • I've added tests for some functions and a simple memory view implementation of a String for testing these functions.

Updated by mrkn (Kenta Murata) about 1 month ago

  • [Feature #16812] Allow slicing arrays with ArithmeticSequence (mrkn)

    • I found the wrong test case, so the implementation was also in wrong state. The proposed patch has been fixed.
    • There are opposing opinions in the following case:
    [0,1,2,3,4,5][(6..0)%-2] #=> [5, 3, 1]
    
    # or
    
    [0,1,2,3,4,5][(6..0)%-2] #=> [4, 2, 0]
    
    • Python follows the former.
    >>> [0, 1, 2, 3, 4, 5][6::-2]
    [5, 3, 1]
