This change fixes the bug described in https://bugs.ruby-lang.org/issues/17880. Checking `ractor_shareable_p` will cause the method to call back into Ruby. Anything calling this method can't be a leaf instruction, otherwise it could crash. By adding `attr bool leaf = false` we no longer crash because it marks the function as not a leaf. Here's a simplified reproduction script: ```ruby require "set" class Id attr_reader :db_id def initialize(db_id) @db_id = db_id end def ==(other) other.class == self.class && other.db_id == db_id end alias_method :eql?, :== def hash 10 end def <=>(other) db_id <=> other.db_id if other.is_a?(self.class) end end class Namespace IDS = Set[ Id.new(1).freeze, Id.new(2).freeze, Id.new(3).freeze, Id.new(4).freeze, ].freeze class << self def test?(id) IDS.include?(id) end end end p Namespace.test?(Id.new(1)) p Namespace.test?(Id.new(5)) ``` Co-authored-by: Aaron Patterson <tenderlove@ruby-lang.org> Co-authored-by: Aaron Patterson <tenderlove@ruby-lang.org> |
