Koichi Sasada 2f50936cb9 Ractor.make_shareable(obj) ... Introduce new method Ractor.make_shareable(obj) which tries to make obj shareable object. Protocol is here. (1) If obj is shareable, it is shareable. (2) If obj is not a shareable object and if obj can be shareable object if it is frozen, then freeze obj. If obj has reachable objects (rs), do rs.each{|o| Ractor.make_shareable(o)} recursively (recursion is not Ruby-level, but C-level). (3) Otherwise, raise Ractor::Error. Now T_DATA is not a shareable object even if the object is frozen. If the method finished without error, given obj is marked as a sharable object. To allow makng a shareable frozen T_DATA object, then set `RUBY_TYPED_FROZEN_SHAREABLE` as type->flags. On default, this flag is not set. It means user defined T_DATA objects are not allowed to become shareable objects when it is frozen. You can make any object shareable by setting FL_SHAREABLE flag, so if you know that the T_DATA object is shareable (== thread-safe), set this flag, at creation time for example. `Ractor` object is one example, which is not a frozen, but a shareable object.		2020-10-21 07:59:24 +09:00
