Embedded arrays aren't moved correctly across ractors

Added by luke-gru (Luke Gruber) 2 months ago. Updated 12 days ago.

Target version:

[ruby-core:116666]

Description

ractor.send(ary, move: true) works incorrectly because if ary is embedded, the new moved object doesn't populate its own embedded space, it uses the MovedObject's embedded space.

example:

r = Ractor.new {
  inner_ary = receive
  values = {}
  values[:equal] = (inner_ary == ["",{},2,3,4,5,6])
  values[:string] = inner_ary.to_s
  values
}
ary = [String.new,Hash.new,2,3,4,5,6]
r.send(ary, move: true)
r_values = r.take
p r_values[:equal]
p r_values[:string]

# => false
# => "[\"\", {}, 2, 2.0, 21747991570, String, 3]"
