Description
The next dev meeting¶
Date: 2020/10/26 13:00-17:00
Place/Sign-up/Agenda/Log: https://github.com/ruby/dev-meeting-log/blob/master/DevelopersMeeting20201026Japan.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: 2020/10/19 (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.

- [Feature #17016] Enumerable#scan_left (parker)
- This is a proposal to add a method to enumerable that accumulates the results of injecting an operation over the enumerable. There is interest in adding this method, but concern about the name. I think that
#accumulate
is a good name. - Should we add this method?
- Is the name
#accumulate
acceptable?

- Improves hashing algorithm
Updated by jeremyevans0 (Jeremy Evans) about 4 years ago
- [Bug #14012] NameError is raised when use class variables in Refinements (jeremyevans0)
- Refinement methods cannot reference class variables of the classes/modules they refine.
- Is this a bug or expected behavior?
- If a bug, how should class variable lookup work in refinement methods?
- [Bug #13768] SIGCHLD and Thread dead-lock problem (jeremyevans0)
- You can end up with thread deadlock even when a signal handler could result in breaking the deadlock.
- I don't think this is a bug, otherwise we would have to skip deadlock detection for all custom signal handlers.
- Do we want add a feature such as
Thread.ignore_deadlock = true
so that we can support this approach?
- [Bug #12485] Kernel.Rational raises TypeError though given denominator returns 1 by to_int (jeremyevans0)
- Do we want Kernel#Rational to fallback to checking for
to_int
ifto_r
is not defined? - If so, is the patch acceptable?
- Do we want Kernel#Rational to fallback to checking for
- [Bug #11808] Different behavior between Enumerable#grep and Array#grep (jeremyevans0)
- Is the current behavior bug or expected?
- @nobu (Nobuyoshi Nakada) has a patch allowing regexp global variables to be available in blocks passed to Enumerable#grep.
- If current behavior is a bug, do we want to use @nobu's patch?
- [Bug #11202] No warning when a link to an original method body was removed (jeremyevans0)
- I don't think this is a bug. Do we want to add a warning in this case?
Updated by jeremyevans0 (Jeremy Evans) about 4 years ago
- [Feature #17143] Improve support for warning categories (jeremyevans0)
- Based on feedback at last month's developer meeting, I'm now proposing adding only two new categories:
:uninitialized_ivar
and:redefine
. - I have a pull request that adds support for those two categories and adds the
:deprecated
category to additional warnings, it is OK?

Updated by Glass_saga (Masaki Matsushita) about 4 years ago
- [Feature #17187] Add connect_timeout to TCPSocket (glass)
- Could I merge it?
Updated by aycabta (aycabta .) about 4 years ago
- [Feature #16746] Endless method definition
- The following was discussed at DevelopersMeeting20200514Japan
Conclusion:
- matz: Let me have some time to consider this issue
def foo() =
ordef foo() :
def foo(n) = n => @x
def foo=bar
may break compatibility (def foo= bar; bar; end
); So, no-arugment mark()
is mandatory. But I may reconsider
- [Feature #15921] R-assign (rightward-assignment) operator
- The following was discussed at DevelopersMeeting20200514Japan
Conclusion:
- matz: The motivation is still valid even after pipeline operator is gave up. It is still useful for a long method chain.
- matz: I think an experiment with commit is needed and works. I will explain.
Updated by ktsj (Kazuki Tsujimoto) about 4 years ago
- [Feature #17260] Promote pattern matching to official feature
- I'd like to remove single line pattern matching and experimental warnings.
Updated by Eregon (Benoit Daloze) about 4 years ago
- [Feature #17259] Kernel#warn should ignore <internal: entries (eregon)
- Currently,
warn('message', uplevel: n)
can show<internal:kernel>:90: warning: message
instead ofcalling_file.rb:42: warning: message
. - https://github.com/ruby/ruby/pull/3647 fixes it, OK to merge?
- Also, RubyGems redefines Kernel#warn for skipping RubyGems' require. That redefinition caused various incompatibilities. If we ignore
<internal:
, no need to redefine Kernel#warn (I'll make a PR to RubyGems).
- Currently,
Updated by marcandre (Marc-Andre Lafortune) about 4 years ago
- [Feature #17171] Have
private
affect constants and singleton methods definitions too (marcandre)- Privacy is important for gems in particular.
private_constant
is verbose to use. - The constants and methods affected would have special flag "legacy public"
- Ruby 3.0: warn (verbose only) on first access to "legacy public"
- Ruby 3.1: warn (always) on first access to "legacy public"
- Ruby 3.2: "legacy public" becomes private
- Privacy is important for gems in particular.
Updated by tenderlovemaking (Aaron Patterson) about 4 years ago
-
[Feature #17176] GC.auto_compact / GC.auto_compact=(flag) (tenderlove)
- Currently compaction is a manual process, eventually I want to make it automatic
- This feature lets users "opt in" to automatic compaction so we can test extensions
- Reference updating logic remains the same so "heap integrity" should be the same
Updated by marcandre (Marc-Andre Lafortune) about 4 years ago
- [Feature #17265] Have common ancestor
Bool
forTrueClass
andFalseClass
