Date: 2017/02/22 (Wed) Time: 14:00- 19:00 (JST) Place: Money Forward inc. Headquarter Sign-up: https://ruby.connpass.com/event/51744/ Attendees: Yukihiro Matsumoto (Matz), Nobuyoshi Nakada, Shyouhei Urabe, Kenta Murata, Akira Matsuda, Akira Tanaka, Yui Naruse, Hiroshi Shibata, Martin Dürst Language: mostly Japanese (sorry for non native Japanese speakers)

Please add your favorite ticket numbers you want to ask to discuss.

  • NOTE
    • 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 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 is scheduled according to when/where we can reserve Matz’s time.

Agenda

  • NOTE: Write at least “ticket number/title/link” and your name (see example below). Explain details on the ticket. If you cannot attend the meeting, we appreciate a short summary because we can understand it more easily (long discussion is difficult to read, especially in a non-native language). Your motivation is also welcome.

About 2.5 timeframe

Log

Date: 2017/02/22 (Wed) Time: 14:00- 19:00 (JST) Place: Money Forward inc. Headquarter Sign-up: https://ruby.connpass.com/event/47745/ log edit: https://docs.google.com/document/d/1fZPbRMn2zjVAflvLz1IFWs3Kdijnm2Um4uNLammqURE/edit log: TBD Next meeting 3/13 at MoneyForward HQ

About 2.5 timeframe https://bugs.ruby-lang.org/projects/ruby-trunk/wiki/ReleaseEngineering25 合宿 project going on no fixed dates yet. hsbt: I will negotiate with ruby association. Current status of Ruby 2.4 Mentainer not fixed yet. naruse: no progress. hsbt: I’ll nudge shugo. matz: 2.1 security maintenance will last until March

Carry-over from previous meeting(s) [Feature #9992] Access Modifiers (Internal Interfaces) matz: the internal visibility is visible from where? nobu: not obvious? shyouhei: there seems to be a looong discussion. matz: seems the OP defines a namespace is a toplevel. matz: not feeling nice to me. [Feature #12968] Allow default value via block for Integer(), Float() and Rational() akr: Integer(string, exception: false) || 0 naruse: that is #12732. matz: seems a bit long? akira: there already are exception: false usages. matz: OK to have either one of them. shyouhei: I’ll comment on #12968 referring #12732. performance? [Feature #12995] Conditional expression taking a receiver outside the condition matz: this is impossible. [Feature #12996] Optimize Range#=== akr: is this compatible? mrkn: seems like that. nobu: breaks old brhaviour if you redefine Range#include? akr: I think that’s acceptable, given you want to subclass a Range. matz: OK then. [Feature #10912] Add method(s) to IPAddr for determining whether an address is link local assign knu. [Bug #13005] Inline rescue is inconsistent when rescuing NoMethodError Martin: I thought rescue keyword was less priotiry. matz: thinking of x = y rescue z, exception is much more likely to happen inside of y, not in x. so rescue should save y. [Feature #13026] Public singleton methods matz: not immediately against it but I want to know the use-case. [Bug #13024] Confusing error message matching a non-ASCII string with ASCII-regex akr: I wrote the message. matz: is it a matter of error message? Martin: delete the “to” word. matz: how about “binary regexp match against…” [Feature #13009] Implement fetch for Thread.current ko1: no objection matz: ditto, ko1: what about ENV? nobu: ENV also has this one. [Feature #13045] Passing a Hash with String keys as keyword arguments matz: this request is NG but I understand the needs of conversion. Make it a new feature request. [Feature #9846] Regexp#to_regexp ko1: is there other method that has #to_regexp? mrkn: Object has. akr: what. ko1: no one prepares to_regexp? akr: conversion nowadays are done by try_convert, no? matz: try_convert was introduced to mean interfaces to C library. nobu: the proposed patch is NG ko1: there will be no to_r? [Feature #13047] Use String literal instead of String#+ for multiline pretty-printing of multiline strings akr: is that more readable? [Feature #8661] Add option to print backstrace in reverse order(stack frames first & error last) akr: why not just do this? matz: I like the idea but… breaks something? shyouhei: if you want to try this, do so today. ko1: either make it customizable, or change the VM. naruse: I don’t like the idea. SEGV output (which is in reverse-order) is hard to read. naruse: also when you log the output it is natural to list in the current order. continue discussion. [Feature #13077] [PATCH] introduce String#fstring method ko1: I don’t want the name fstring. matz: -@ seems OK. [Feature #13083] {String|Symbol}#match{?} with nil returns falsy as Regexp#match{?} matz: it seems #match should raise instead. [Feature #12508] Integer#mod_pow matz: OK. go ahead. [Misc #13072] Current state of date standard library naruse: This ticket is great. It summarizes the current situation quite accurately. akr: we don’t want to merge Date with Time. shyouhei: independent from the future of Date, we are going to separate Date._parse. Right? [Feature #13097] Deprecate Socket.gethostbyaddr and Socket.gethostbyname akr: I think we should implement gethostbyaddr on top of getaddrinfo. From attendees [Bug #13225] [DOC] expand docs for Date shifting hsbt: I want him to be a committer. matz: OK. nobu: I have seen no problem on his past patches. [Feature #13156] In-tree copy of ruby/spec duerst: this way you can commit ruby and spec at once. shyouhei: neutral. duerst: +. it is easier than separate repo ko1: somewhat -. github has more user base. naruse: several reasons to object: 2.3 left unchanged. mspec lacks some feature. CF [ruby-core:79088] I don’t think we are going to maintain both test-all and test-rubyspec. We are either going to switch to rubyspec, or to remain test-all. And I don’t think we are going to abondon test-all. nobu: somewhat negative. akr: I’d like to propose more use of test-all. test-all tends to have tests for new features. I think it’s easier to use it than to change core people. [Feature #13133] TracePoint: Add event type for constant access hsbt: I want ko1 to look at it. ko1: this will introduce other trace hooks. ko1: trace overhead is OK when enabled but is a problem when not traced at all. Current implementation has overhead when on such situation. akr: regeneration of binary is needed to reroute that I think. [Feature #13197] Gemify fileutils https://bugs.ruby-lang.org/issues/13197#note-4 hsbt: there already are gems named “fileutils” or “dbm”… rubygems.org blocked these namespaces from future additions, but they are there already. pathname depends on fileutils. [Feature #13240, Feature #13241] Change Unicode property implementation / Method(s) to access Unicode properties (duerst) Martin: currently we can know if a string contains, say, Hiragana, but there is no way to say what script the given string is. akr: onigumo issue should be reported to their repo. Martin: that was not what we did for unicode-aware cases akr: if this feature is merged to onigumo then it’s OK. But if they reject, we should not introduce our own modified version of onigumo. naruse: I want to use this feature shyouhei: but who others? akr: do we plan to have the whole Unicode property DB? If so, should that be a part of onigumo? naruse: including the entire set of Unicode DB in the ruby.tar.gz sounds too big.
