[ruby-core:112248] [Ruby master Bug#19409] Object's shape is reset after a ractor move

Issue #19409 has been updated by hsbt (Hiroshi SHIBATA). Status changed from Open to Assigned Assignee set to ko1 (Koichi Sasada) ---------------------------------------- Bug #19409: Object's shape is reset after a ractor move https://bugs.ruby-lang.org/issues/19409#change-101675 * Author: luke-gru (Luke Gruber) * Status: Assigned * Priority: Normal * Assignee: ko1 (Koichi Sasada) * Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- I believe an object should have the same shape after being moved from 1 ractor to another. ```ruby class Obj attr_accessor :a, :b, :c, :d def initialize @a = 1 @b = 2 @c = 3 end end r = Ractor.new do obj = receive #p RubyVM::Shape.of(obj) obj.d = 4 p obj.a, obj.b, obj.c, obj.d # gets wrong values due to object shape id being reset on object end obj = Obj.new #p RubyVM::Shape.of(obj) r.send(obj, move: true) r.take ``` -- https://bugs.ruby-lang.org/
