Description
The next dev meeting¶
Date: 2022/08/18 13:00-17:00 (JST)
Log: https://github.com/ruby/dev-meeting-log/blob/master/DevMeeting-2022-08-18.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 record of the discussion in the 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 of the meeting 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 2022/08/15. 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 zverok (Victor Shepelev) about 2 years ago
- [Feature #18368]
Range#step
semantics for non-Numeric
ranges (zverok)- Proposal to reimplement
(a..b).step(c)
via+
, or provide another method with this behavior - More clarifications provided & answers to the questions after last dev.meeting
- Proposal to reimplement
- [Bug #18580]
Range#include?
inconsistency for beginless String ranges- "This was discussed during the February 2022 developer meeting, and @matz (Yukihiro Matsumoto) said he needs more time to consider it."
- [Feature #17330]
Object#non
(zverok)- Proposal to introduce generic "nullify if unacceptable" API (zverok)
- more explanations and examples provided
- [Feature #16122]
Struct::Value
: simple immutable value object (zverok)- The ticket is in weird state. It has "Status: Feedback", but generic state "CLOSED", but I don't see any notice of HOW it was closed?.. Is it RedMine glitch?.. I don't see an option to reopen it.
- The latest comment from Matz seems to lean towards accepting proposal, the only culprit is a name: "Struct::Value seems acceptable to him, but he wanted to seek a better name. Devs suggested Tuple, NamedTuple, and Record, but none of them seemed to fit for him."
- Can we somehow move forward with this?
- [Feature #18934] Introduce method results memoization API in the core (zverok)
- New ticket, proposing and justifying simple
memoized def method_without_args
- New ticket, proposing and justifying simple
Updated by byroot (Jean Boussier) about 2 years ago
- [Feature #18944] Add
SizedQueue#push(timeout:)
(byroot)- Matz said this should be required separately.
- When implementing
Queue#pop(timeout:)
it was very evident this was needed. - Spec is return
self
on success,nil
on timeout, likepop
. - Useful to periodically do heartbeat, drop messages, etc when waiting to push on a queue.\
- [Feature #18885] End of boot advisory API (byroot)
- e.g. something like
RubyVM.prepare
, orRubyVM.ready
. - Would allow applications to notify the VM that they're done loading and about to process user input.
- Could be used by the VM to enable some optimizations, such as precomputing constant caches, etc.
- Particularly useful for forking server, but not only.
- e.g. something like
Updated by jeremyevans0 (Jeremy Evans) about 2 years ago
- [Bug #18955] Kernel#sprintf - %c ignores a non-ASCII character's encoding (jeremyevans0)
- Do we want the %c format specifier to transcode a string argument to the format string's encoding before taking the first character?
- [Bug #18958] Kernel#sprintf doesn't apply format sequence in some encodings (jeremyevans0)
- Should we raise an ArgumentError when the format string is in an incompatible encoding?
- The encodings listed in the issue are not the same as those that are not
ascii_compatible?
. - If we do want to raise an exception for this, do we want a new encoding flag for this, or a hardcoded list of incompatible encodings?
- [Bug #18797] Third argument to Regexp.new is a bit broken (jeremyevans0)
- Do we want to deprecate passing a third argument to Regexp.new?
- [Bug #18767] IO.foreach hangs up when passes limit=0 (jeremyevans0)
- Is the current infinite loop in this case expected, or should it raise an ArgumentError as IO.readlines does?
Updated by Eregon (Benoit Daloze) about 2 years ago
- [Feature #18949] Deprecate and remove replicate and dummy encodings (eregon)
- I will try to attend the dev meeting. Would it be possible to discuss this towards the end of the meeting, 16 JST (= 9am CEST) my preference, or if better 15 JST (= 8am CEST)?
- There are multiple things to decide, see https://bugs.ruby-lang.org/issues/18949#To-Decide
-
- (
Encoding#replicate
andrb_define_dummy_encoding()
) is most important (for complexity & performance) and given the extremely low usage it seems safe to deprecate and then remove
- (
-
- Handling the dummy UTF-16 and UTF-32 encodings, seems used very rarely but harder to assess. It causes significant performance overhead. Discussion e.g. in https://bugs.ruby-lang.org/issues/18949#note-23
-
- Multiple devs want to keep (other) existing dummy encodings based on usages, so let's keep them for now. Maybe we could make them non-dummy or only available for transcoding in the future.

[Feature #18408] Allow pattern match to set non-local variables
- That would make, in particular,
42 => @a
possible- This addition seems natural after we added non-local vars support for pinning
- It also "restores" the original rightward assignment functionality
- Here is a PR attached: https://github.com/ruby/ruby/pull/5426

Updated by Eregon (Benoit Daloze) about 2 years ago
- [Bug #18729] Method#owner and UnboundMethod#owner are incorrect after using Module#public/protected/private (eregon)
- Also [Bug #18435] and [Bug #18751], they are all the same issue basically.
- Let's attempt to stop hiding ZSUPER methods, this was never tried and I think would cause little incompatibilities. OK to try this?
- The semantic model after that change will finally make sense for users and Ruby implementers, instance_methods reflects the method table, owner means in which module's method table the method is.
- Also this will mean ZSUPER methods are just an internal implementation detail on CRuby, other Ruby impls are free to use something else like shallow-copy (like alias_method does) but instance_methods/owner/etc will be the same for the user.
- The hiding is actually "exposing" ZSUPER methods to Ruby users because other Ruby implementations don't use ZSUPER methods and don't hide the visibility-created methods.

We could not finish all the agenda in time. We will continue on 25th.
Updated by Eregon (Benoit Daloze) about 2 years ago
- [Feature #18798]
UnboundMethod#==
with inherited classes (eregon)- OK to change UnboundMethod#== to check if same method definition (and ignore from which class instance_method was used on)?
- If not, OK to add
{Method,UnboundMethod}#same_definition?(other)
?
