DevMeeting-2017-12-12

Date: 2017/12/12 (Tue) Time: 14:00- 18:00 (JST) Place: Speee Inc. Sign-up: https://ruby.connpass.com/event/73509/ log edit: https://docs.google.com/document/d/1XbUbch8_eTqh21FOwj9a_X-ZyJyCBjxkq8rWwfpf5BM/edit Attendees: (add your name here if you would like to participate) Martin Dürst Regrets: (add your name here if you often attend, but can’t attend this time) 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

Carry-over from previous meeting(s) From attendees The tickets below are old tickets whose status is open or assigned (and mame can somewhat understand) matz [Feature #11256] anonymous block forwarding Matz: it’s a good property to avoid naming variables. Also I personaly like it. However prompting such name-less programming might let people write cryptic codes. Matz: hmm… Made up my mind. Accepted. [Feature #4288] Allow invoking arbitrary method names with foo.”something” syntax Matz: use send. [Bug #4352] [patch] Fix eval(s, b) backtrace; make eval(s, b) consistent with eval(s) Matz: let’s try this in 2.6. [Bug #4443] odd evaluation order in a multiple assignment [Feature #4475] default variable name for parameter [Feature #4830] Provide Default Variables for Array#each and other iterators [Feature #4513] allow whitespace following EOL continuation backslash [Feature #4514] #deep_clone and #deep_dup for Objects [Feature #4521] NoMethodError#message may take very long to execute [Feature #4539] Array#zip_with [Feature #5044] #zip with block return mapped results [Feature #4541] Inconsistent Array.slice() [Feature #4592] Tempfileを直接保存したい [Feature #4780] String#split with a block [Feature #4818] Add method marshalable? [Feature #4824] Provide method Kernel#executed? [Feature #4907] enumerable#permutation and combination [Feature #4910] Classes as factories [Feature #4921] Remove intern.h [Feature #4938] Add Random.bytes [patch] [Feature #5007] Proc#call_under: Unifying instance_eval and instance_exec [Feature #5064] HTTP user-agent class [Feature #5120] String#split needs to be logical [Feature #5123] Alias Hash 1.9 as OrderedHash [Feature #5129] Create a core class “FileArray” and make “ARGF” its instance [Feature #5133] Array#unzip as an alias of Array#transpose [Bug #5179] Complex#rationalize and to_r with approximate zeros [Feature #5206] ruby -K should warn [Feature #14043] Introduce Process.last_status as an alias for $? Matz: OK. Ruby3.0 depretation warnings %? Already error backtick ()? Matz: I’d like to let people override backticks in 3 Naruse: migration will be add %x before … Sorah: People tend to wrongly use backtick. This is a side topic, but I’d like to remove both backtick and %x if we sunset current Or, disable interpolation for %x? Yui-knk: what to do for backtick heredocs? I.e. «End is replaced with self.send(:`, «”End”) which is clumsy -K Sorah: ko1? Naruse: why we have -K is ko1 complained for deletion before. Ko1: I no longer use it. Etc. Hsbt: $-something? Akr: we no longer need for instance $/, etc. $/ input record separator (default argument for “gets”) $\ output record separator (“print” prints it at last) $, default separator for Array#join and print $; default separator for String#split Akira: what about all other global variables? Matz: global variables are not going to fade out. Akira: class variables? Ruby3 Concurrent model (AutoFiber? Guild?) Matz: would like to hear about this topic from ko1. Maybe next meeting? nobu [Feature #2324] Dir instance methods for relative path [Bug #3618] inf-ruby prompt and tab completion [Feature #4924] mkmf have_header fails with C++ headers ko1 [Feature #2447] reduce GC pressure by symbol table without String instance [Feature #3187] Allow dynamic Fiber stack size [Feature #3731] Easier Embedding API for Ruby [Bug #4040] SystemStackError with Hash[*a] for Large a naruse [Feature #2567] Net::HTTP does not handle encoding correctly [Feature #2631] Allow IO#reopen to take a block [Bug #4173] TestProcess#test_wait_and_sigchild が、たまに失敗する akr [Feature #3608] Enhancing Pathname#each_child to be lazy [Feature #3848] Using http basic authentication for FTP with Open URI [Feature #4560] [PATCH] lib/net/protocol.rb: avoid exceptions in rbuf_fill knu [Feature #3953] TCPSocket / UDPSocket do not accept IPAddr objects. mame [Feature #4247] New features for Array#sample, Array#choice suke [Bug #4405] WIN32OLE & Threads incompatible kosaki [Feature #4464] [PATCH] add Fcntl::Flock object for easier use of POSIX file locks yugui [Feature #4831] Integer#prime_factors mrkn [Feature #4968] BigDecimal#sqrt は BigMath.sqrt へ移動すべき hsbt [Bug #5060] Executables in bin folder conflict with their gem versions. sorah [Feature #14141] Add a method to Exception for retrieving formatted exception for logging purpose (Exception#{formatted,display}) Nobu: direction? Sorah: depends on global tty Akr: eh… Mame: what about implementing #display first, then think about the name of method returning a String? Akr: I propose #long_message Akira: or #full_message Sorah: *_message sounds they don’t interact with TTYs. Matz: accept #full_message anyone [Feature #4017] [PATCH] CSV parsing speedup [Bug #4157] test_pty で、たまに出る Failure [Feature #4483] PStoreをデフォルトで複数のスレッドから扱えるようにしたい From non-attendees [Feature #14143] Thread.report_on_exception should be true by default. (eregon): Can we have the opinion of matz on this? Matz: Understand the needs but not for 2.5. For future versions, compatibility concerns should be considered. Ko1: I think we should make this default on ideally. We need a good transition path. No idea though. Akr: it sounds finding a transition path is not a practical story. Naruse: I’ll comment that it’s too late for 2.5. Matz: OK, let’s do it in RC1. To see what happens. [Feature #11816] Partial safe navigation operator (marcandre) Matz: I’ll respond. [Feature #14015] Enumerable & Hash yielding arity (marcandre) nobu: it’s due to we didn’t have rb_yield_values before. Nobu: Changing this can break existing codes. Maybe add warning? Matz: warning might be an option. Akr: this example uses lambda, which should be strict about parameter passing. I think exceptions are what it should behave. Matz: I understand there has inconsistency and error prone. Let me find the reason for status quo, as well as a solution. Ko1: is it OK we won’t fix this in 2.5? Matz: OK. https://bugs.ruby-lang.org/issues/12882 (jeremyevans) Matz: OK, accepted. Shyouhei: I’ll merge. Mame: isn’t jeremy a committer? Hsbt: no. Matz: but it might be a good time for him to be.

[#11925] (k0kubun)

K0kubun: made a patch Matz: understand the needs. Name? Shyouhei: is keyword_args: OK? Sorah: no other methods have this keyword Akira: the concept named keyword arguments are not exposed into Ruby’s world. Mame: if we split kwargs and argv, we don’t even need this method? Conclusion: No create! feature keyword_init: true

[#14162] (k0kubun)

Nobu: this is a bug. Will fix.

[#12275] (shyouhei)

Shyouhei: tadd wanted you guys to review the patch.

[#14142] (akira)

Matz: seems okay to me. Knu: this feature has a minor compatibility issue Nobu: I don’t think that cause any trouble.

[#14052] (akr)

Akr: naming? Nobu: what about use Array instead? Shyouhei: sample Akr: that’s NG because what is generated is different. Matz: with_chars sounds no good.
