Description
The next dev meeting¶
Date: 2022/02/17 13:00-17:00 (JST)
Log: https://github.com/ruby/dev-meeting-log/blob/master/DevMeeting-2022-02-17.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 2022/02/14. 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.

- [Feature #13110] Byte-based operations for String
- Are there any objections to introduce byteindex, byterindex and byteoffset? (not bytesplice)
- Should the method names be
byte_index
,byte_rindex
, andbyte_offset
?

- [Feature #18249] The ABI version of dev builds of CRuby does not correspond to the ABI
- ABI checking for development Ruby.
- Calculates the MD5 hash of header files during compilation of Ruby, stores this MD5 in native extensions, and compares the values when loading the binary.
- Prevents incompatible binaries from being loaded, which can cause bugs, crashes, or other incorrect behavior.
- Summary of motivation here: https://bugs.ruby-lang.org/issues/18249#note-15

- [Feature #18498] Introduce a public
WeakKeysMap
that compares by equality (byroot)- Ruby's current weak reference constructs are not very usable.
- The most useful weak collection that is offered by most platform is
WeakKeysMap
- The keys would be weak references, but the values would be strong references
- It would use equality semantic, just like a regular Hash

- [Feature #18568] Explore lazy RubyGems boot to reduce need for --disable-gems
- With more and more default gems, RubyGems has become a major part of Ruby's startup time.
- On CRuby, the base boot time is reduced by 80% using
--disable-gems
. - Several ruby-core members would like to remove
--disable-gems
but others and some users need it for fast command line tools. - It seems like it is time to eliminate the overhead of booting RubyGems and default gemspecs.

[Feature #18566] Merge io-wait
gem into core IO
class. (byroot)
- It's very small and any non-trivial IO code will require it.
- Merge io-wait into io.c for Ruby 3.2
- Remove io-wait as a dependency of all gems maintained by ruby-core (e.g. net-protocol).
- Publish a new io-wait version that is simply an empty gem.
- Add a
lib/io/wait.rb
stub, with eventually a deprecation warning. - @normalperson (Eric Wong) suggest to do the same with
io-nonblock
.

Please just keep lib/io/wait.rb stub empty indefinitely. No
need for deprecation warning, just a no-op is fine and don't
cause pain for existing users. I don't want to hurt:
- users who aren't coders
- users who lack permissions to change code
- codebases which need to support both old/ancient Rubies + new ones
I'm looking at system-wide implications from distro-installed Rubies;
not from a webapp+bundler perspective.

Actually, Benoit suggested io-nonblock. I suggested going beyond that :)

- [Bug #18487] Kernel#binding behaves differently depending on implementation language of items on the stack (jeremyevans0)
- Is it OK to limit Kernel#binding to only look at the preceding frame, instead of the closest Ruby-level frame?
- If so, is the patch acceptable?
- [Bug #16663] Add block or filtered forms of Kernel#caller to allow early bail-out (jeremyevans0)
- Since the last developer meeting, a prototype has been created.
- Is the behavior of the prototype acceptable?
- Incorrect usage with
to_enum
raisesStopIteration
instead of crashing. Is that acceptable?
- [Bug #14103] Regexp absense operator has no chance to
^C
(jeremyevans0)- One possible way around this is checking for interrupts and potentially yield to another thread every N times during backtracking.
- I submitted a pull request to do that (N = 1000), and it fixes the example given.
- Is such an approach acceptable? If so, is the patch acceptable?
- One issue not addressed by the patch is the modification of the string being searched by another thread during regexp evaluation (potentially causing a crash), but I'm not sure whether that is possible.

- [Feature #18339] GVL instrumentation API
- The goal is to be able to measure GVL contention and tell users if they use too many threads for their workload.
- It would allow to instrument the GVL which is a key metric for threaded environments, and to tune concurrency in applications.
- I implemented a (posix only for now) draft: https://github.com/ruby/ruby/pull/5500.
- The overhead when no hook is registered is just a single unprotected boolean check, so close to zero.
-
rb_gvl_hook_t * rb_gvl_event_new(rb_gvl_callback callback, rb_event_flag_t event)
to register a hook. -
bool rb_gvl_event_delete(rb_gvl_hook_t * hook)
to unregister it. - Is the general idea acceptable?
- Any API change before I try to implement the Windows version?

- [Feature #12962] Adding "friend" method visibility
- Allow libraries with Object Oriented internals to call "not public" methods
- Useful when "protected" is too restricted, but the method shouldn't be "public"
- Refinements can't help because they are lexically scoped
- It's easier to add method visibility than to move all code around
Updated by zverok (Victor Shepelev) over 2 years ago
- [Bug #18580]
Range#include?
inconsistency for beginless String ranges (zverok)-
(...'z').include?('ww')
works for strings, due to historical reasons - there is no semantical justification for it, and it is confusing for users

- [Feature #18576] Rename
ASCII-8BIT
encoding toBINARY
- The
ASCII-8BIT
name is very confusing for beginners. - Even for people who know what it is, it can easily be misread as
US-ASCII
- It has been aliased as
BINARY
for a very long time, and in the vast majority of the case it's a better description. - I expect the backward compatibility problems to be very minimal (limited to
Encoding#name
).

- [Feature #18589] Finer-grained constant invalidation (Kevin Newton)
- We want to trade a very small memory increase for much better constant cache invalidation.
- This will allow relying on more stable constant caches for better code specialization in JITs.
- This can also help speed up initial boot times since caches are currently invalidated each time a class is created.
