NOTES

• 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

Next dev-meeting

About 2.7 timeframe

Check security tickets

Carry-over from previous meeting(s)

From Attendees

• [Feature #15554] warn/error passing a block to a method which never use a block (ko1)
  • I want to share the ticket and survey on some product.

From non-attendees

• [Feature #6470] Make attr_accessor return the list of generated method (eregon)
  • I think not all related issues were considered. There are use cases, both for private attr_* and other modifiers (e.g., volatile, atomic, tracing accesses, getter/setter decorators, etc).
• [Bug #14353] $SAFE should stay at least thread-local for compatibility (eregon)
  • I would like matz's opinion on this. It seems the compatibility risks and debugging problems is not worth making $SAFE global, unless there is a good reason to be global? Should there still be $SAFE checks at all, for e.g., tainted Strings?
• [Feature #5653] "I strongly discourage the use of autoload in any standard libraries" (eregon)
  • It would be useful to reach a decision for this. What does it gain, and at what cost for compatibility? Is there going to be a replacement?

Please comment your favorite ticket we need to discuss with the following format.

* [Ticket ref] Ticket title (your name)
  * your comment why you want to put this ticket here if you want to add.

Your comment is very important if you are no attendee because we can not ask why you want to discuss about it.

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 about this feature.

We don't guarantee to put tickets in agenda if the comment violate the format (because it is hard to copy&paste).

[aycabta (aycabta .)]

• [Feature #4475] default variable name for parameter (aycabta)
  • In #15483, matz said "I feel the expression ary.map(&(:to_i << :chr)) is far less readable than ary.map{|x|x.to_i.chr}.", and "And this can lead to the default block parameter like it."

[mame (Yusuke Endoh)]

• [Feature #11076] Enumerable method count_by
  • A new name "tally" is proposed. "Tally" is: | → || → ||| → |||| → ||||. Looks good to me. What do you think?

[kddnewton (Kevin Newton)]

• [Feature #14344] refine at class level (kddeisz)
  • Shorter refinement syntax proposed based on common use cases. Proposed either refine_class or using blocks for shorthand. What do you think?
• [Feature #14680] Adding +@ and -@ to hash and array (kddeisz)
  • Since we have -@ and +@ for strings and it's very useful I'd like to propose adding the same API to hash and array.

[ioquatix (Samuel Williams)]

• [Feature #15567] Allow ensure to match specific situations. (ioquatix)
  • Could we discuss whether this is a good idea or not?
• [Feature #15560] Add support for read/write offsets. (ioquatix)
  • Can we get consensus on whether we can add this?

[mrkn (Kenta Murata)]

• [Feature #15573] Permit zero step in Numeric#step and Range#step
  • I make this issue as a feature request because the behaviors exist at least since version 2.3. But I think it is a bug, so it should be resolved.

[hsbt (Hiroshi SHIBATA)]

• [Feature #15581] Split tool/* files to tool and script directories
  • What's a concern about this?

[bdewater (Bart de Water)]

• [Feature #10098] Timing-safe string comparison for OpenSSL::HMAC (bdewater)
  • The feature is done (the title is old, it will be implemented in String) but blocked on picking a mehod name. I would like to ask for opinions so this can move forward.
