[ruby-core:100260] [Ruby master Misc#17200] DevelopersMeeting20201026Japan

Issue #17200 has been updated by jeremyevans0 (Jeremy Evans).


* [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` if `to_r`  is not defined?
  * If so, is the patch acceptable?
* [Bug #11808] Different behavior between Enumerable#grep and Array#grep (jeremyevans0)
  * Is the current behavior bug or expected?
  * @nobu 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?

# The next dev meeting

**Date: 2020/10/26 13:00-17:00**
Place/Sign-up/Agenda/Log: *TBD*

- 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:

```

  * 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](https://gist.github.com/mame/b0390509ce1491b43610b9ebb665eb86).  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.
