Description
The next dev meeting¶
Date: 2021/11/18 13:00-17:00 (JST)
Place/Sign-up/Agenda/Log: https://github.com/ruby/dev-meeting-log/blob/master/DevelopersMeeting20211118Japan.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.
- It is recommended to add a comment by 2021/11/15. We hold a preparatory meeting to create an agenda a few days before the dev-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. We appreciate it if you could write a short summary and update from a previous discussion.

Updated by shugo (Shugo Maeda) almost 3 years ago
- [Feature #12737] Module#defined_refinements (shugo)
- It's good to have for debugging purposes. Users can see refinements defined in a module in irb etc. without reading code.
- [Feature #14332] Module.used_refinements to list refinement modules (shugo)
- It's good to have for debugging purposes. Users can see all activated refinements in a given scope.
Updated by shugo (Shugo Maeda) almost 3 years ago
- [Bug #18270] Refinement#{extend_object,append_features,prepend_features} should be removed
- Refinements are different from normal modules, so it's potentially dangerous to use refinements as mixins.
- Why not deprecate them in Ruby 3.1, and remove them in Ruby 3.2.

- [Feature #16252] Hash#partition should return hashes (dan0042)
- More consistent with
select
/reject
- More in line with existing usage (most people seem to convert the results to hashes)
- More efficient than arrays of arrays
- Mostly compatible
- More consistent with
Updated by Eregon (Benoit Daloze) almost 3 years ago
- [Misc #18285] NoMethodError#message uses a lot of CPU/is really expensive to call (eregon)
- OK to do https://bugs.ruby-lang.org/issues/18285#note-11 and no longer call custom #inspect for NoMethodError?
- Same for NameError?
- [Bug #18243] Ractor.make_shareable does not freeze the receiver of a Proc but allows accessing ivars of it (eregon)
- How about this approach to fix it https://bugs.ruby-lang.org/issues/18243#note-9?
- I think passing a Proc with a non-shareable
self
to a Ractor is highly confusing semantically and in practice, and it's prone to bugs.

- [Feature #18287] Support nil value for sort in Dir.glob (eregon)

Updated by jeremyevans0 (Jeremy Evans) almost 3 years ago
- [Feature #6210] load should provide a way to specify the top-level module (jeremyevans0)
- This is fairly easy to implement in a backwards compatible manner, and seems useful.
- Are we OK adding this feature? If so, is the pull request acceptable?
- [Feature #11256] anonymous block forwarding (jeremyevans0)
- This was accepted by @matz (Yukihiro Matsumoto) four years ago, but never committed.
- I've created a new working version based on patches from @nobu (Nobuyoshi Nakada) and @mame (Yusuke Endoh).
- There should be no backwards compatibility issues, as the proposed syntax is currently invalid.
- Is it OK to add this feature? If so, is the pull request acceptable?
- [Feature #11689] Add methods allow us to get visibility from Method and UnboundMethod object. (jeremyevans0)
- As requested by @matz (Yukihiro Matsumoto), I put together a patch for #public?, #private?, and #protected?.
- Do we want to use this approach, or do we want to reconsider the #visibility method that returns a symbol?
- If we want to use this approach, is the pull request acceptable?
- [Feature #12495] Make "private" return the arguments again, for chaining (jeremyevans0)
- This seems useful, and the backwards compatible issues are quite small.
- Are we OK adding this feature? If so, is the pull request acceptable?
- [Feature #16663] Add block or filtered forms of Kernel#caller to allow early bail-out (jeremyevans0)
- Currently it is not possible to generate a partial backtrace without knowing how many frames you need up front.
- This feature allows the production of partial backtraces without that knowledge.
- For example, you can use it to return the only the first frame that meets some criteria.
- There shouldn't be any backwards compatibility issues, as caller/caller_locations does not currently use a block.
- Are we OK adding this feature? If so, is the pull request acceptable?

Updated by duerst (Martin Dürst) almost 3 years ago
- [Feature #18336] How to deal with Trojan Source vulnerability
- For [A], Bidi characters, I think "wait and see" may be the right decision, but it should be explicit.
- [Feature #18337] Ruby allows zero-width characters in identifiers
- Suggest to use https://www.unicode.org/reports/tr31/, to catch up with other languages.

Warning: Please read the instruction carefully. You must briefly write what you want us to discuss as a comment. It is ideal if we can start discussing without reading the ticket itself.

[Feature #18339] GVL instrumentation API
- I'd like 3 new internal tracepoints:
RUBY_INTERNAL_EVENT_GVL_ACQUIRE_ENTER
,RUBY_INTERNAL_EVENT_GVL_ACQUIRE_EXIT
,RUBY_INTERNAL_EVENT_GVL_RELEASE
- It would be also very useful if the number of waiting thread was part of the hook arguments.
- It would allow to instrument the GVL which is a key metric for threaded environments, and to tune concurrency in applications.
- Is the feature acceptable?
- Any performance concerns when no hook is registered?
