Issue #22107 has been updated by himura467 (Akito Shitara). * [Feature #22186] Increase the embeddable size limit for substrings created by `str_subseq()` (himura467) * `str_subseq()` embeds a sharable middle substring only when it fits in the smallest RString slot (about 23 bytes), even though VWA supports embedded strings up to 1024 bytes. Sizing the allocation to the actual substring length via `STR_EMBEDDABLE_P()` / `str_alloc_embed()` improves fluentd by roughly 12% on ruby-bench. * The fluentd improvement observed in #19315#note-52 seems to be attributable to this change (it was included in that branch), not to `SHARABLE_MIDDLE_SUBSTRING` itself. This fix is self-contained, does not touch the `RSTRING_PTR()` null-termination contract, and seems worth landing independently of #19315. * Is this approach acceptable?

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 2026/07/06. 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. -- https://bugs.ruby-lang.org/
