07:02 AM Ruby Revision 2e5bf429 (git): Ractor: restrict class/module modification to the creator Ractor

Only the Ractor which created a class/module may modify it: define, remove or
undefine methods, alias, include/prepend, refine, define or remove constants,
register an autoload, and set the class's own instance variables. Reading is
unc... ko1 (Koichi Sasada)

07:02 AM Ruby Revision 6b9a29a1 (git): Ractor: bring class variables under the class owner

A class variable is shared across the inheritance chain and the class it is
stored in can migrate (cvar_overtaken), so the deciding Ractor is the owner of
the class the variable is actually stored in, not of the receiver it was looked
up... ko1 (Koichi Sasada)

07:02 AM Ruby Revision 3cb67a20 (git): Ractor: check unshareable leaks when copying a foreign class

Module#initialize_copy (Class#dup etc.) of a class/module created by another
Ractor makes a copy owned by the copying Ractor. Since an owner may read the
unshareable constant and instance variable values of its own classes, a raw
table ... ko1 (Koichi Sasada)

07:02 AM Ruby Revision f8485f7d (git): Ractor: make freeze and set_temporary_name owner-only

Requested by matz on [Feature #22226]: a non-owner freezing somebody else's
class is a hole, because it lets a third party make a class permanently
unmodifiable. Naming is the same kind of change to the class itself.

07:02 AM Ruby Revision b8e5bf55 (git): Ractor: check ownership on visibility changes

set_method_visibility only called rb_check_frozen, so public/private/protected
and module_function never met the ownership check, even though the proposal
lists visibility changes as owner-only. A non-owner Ractor could rewrite the
meth... ko1 (Koichi Sasada)

07:02 AM Ruby Revision f5a57659 (git): Ractor: move a singleton class's ownership with its object

A singleton class belongs to the owner of the object it is attached to, and
Ractor#send(move: true) hands that object over. Without this the receiver could
define singleton methods on a moved object only when its singleton class had not... ko1 (Koichi Sasada)

07:02 AM Ruby Revision f0bae5f7 (git): Update doc/language/ractor.md and bootstraptest for class/module ownership

Document the model: only the creator Ractor can modify a class/module,
singleton class ownership follows the attached object, classes of a terminated
Ractor become read-only, and the main-Ractor-only rules for class instance
variables, c... ko1 (Koichi Sasada)
