[ruby-core:121342] [Ruby master Bug#20340] Ractor comments not applying to constant targets

From: "kddnewton (Kevin Newton) via ruby-core" <ruby-core@...>
Date: 2025-03-13 13:50:03 UTC
List: ruby-core #121342
Issue #20340 has been updated by kddnewton (Kevin Newton).

Status changed from Open to Closed

Based on https://bugs.ruby-lang.org/issues/21016#note-4, I think this is the expected behavior.

----------------------------------------
Bug #20340: Ractor comments not applying to constant targets
https://bugs.ruby-lang.org/issues/20340#change-112314

* Author: kddnewton (Kevin Newton)
* Status: Closed
* Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN
----------------------------------------
In this example:

```ruby
C, = { foo: bar }
```

You get:

```
== disasm: #<ISeq:<main>@test.rb:1 (1,0)-(1,17)>
0000 putobject                              :foo                      (   1)[Li]
0002 putself
0003 opt_send_without_block                 <calldata!mid:bar, argc:0, FCALL|VCALL|ARGS_SIMPLE>
0005 newhash                                2
0007 dup
0008 expandarray                            1, 0
0011 putspecialobject                       3
0013 setconstant                            :C
0015 leave
```

But there's no difference from:

```ruby
# shareable_constant_value: literal
C, = { foo: bar }
```

I would have expected:

```
== disasm: #<ISeq:<main>@test.rb:1 (1,0)-(2,16)>
0000 putobject                              RubyVM::FrozenCore        (   2)[Li]
0002 putobject                              :foo
0004 putobject                              RubyVM::FrozenCore
0006 putself
0007 opt_send_without_block                 <calldata!mid:bar, argc:0, FCALL|VCALL|ARGS_SIMPLE>
0009 putobject                              "C"
0011 opt_send_without_block                 <calldata!mid:ensure_shareable, argc:2, ARGS_SIMPLE>
0013 newhash                                2
0015 opt_send_without_block                 <calldata!mid:make_shareable, argc:1, ARGS_SIMPLE>
0017 dup
0018 expandarray                            1, 0
0021 putspecialobject                       3
0023 setconstant                            :C
0025 leave
```

Is this omission intentional? For context, I'm building this in prism and I need to know if I should explicitly disable this behavior.
