[ruby-core:118961] [Ruby master Misc#20660] DevMeeting-2024-09-05

Issue #20660 has been updated by byroot (Jean Boussier).


* [Feature #20594] A new String method to append bytes while preserving encoding (byroot)
  * Continuation from previous meeting
  * Alan proposed the method to be named `append_as_bytes`, to be variadic and accept both String and Integer (so like the original proposal).
  * For integer the behavior would be the same as `setbyte`, so mask `0x80`.
  * Early [implementation prototype show a ~13% gain on our benchmark](https://github.com/Shopify/protoboeuf/pull/116#issuecomment-2309750217).

* [Feature #20684] Add optimized instructions for frozen literal Hash and Array (byroot)
  * Allow to avoid having to define `EMPTY_HASH = {}.freeze` or `EMPTY_ARRAY.freeze` constant in hotspots (see code samples in the issue).
  * Also give some minor gains when defining frozen constants.
  * Not a big optimization, but a very small patch and help usability.

# The next dev meeting

**Date: 2024/09/05 13:00-17:00** (JST)
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 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 2024/09/02. 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](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. We appreciate it if you could write a short summary and update from a previous discussion.
