In 2.6, SimpleDelegator would always use the target `respond_to?`
In 2.7.0 it doesn't if the target does not inherit from Object.
This breaks compatibility for delegated objects that inherit
from BasicObject and redefine `respond_to?`.
This makes it possible to initialize_clone to correctly not freeze
internal state if the freeze: false keyword is passed to clone.
If clone is called with freeze: true or no keyword, do not pass
a second argument to initialize_clone to keep backwards
compatibility.
This makes it so that external libraries that override
initialize_clone but do not support the freeze keyword will fail
with ArgumentError if passing freeze: false to clone. I think that
is better than the current behavior, which succeeds but results in
an unfrozen object with frozen internals.
Fix related issues in set and delegate in stdlib.
Fixes [Bug #14266]
(old)
test.rb:4: warning: The last argument is used as the keyword parameter
test.rb:1: warning: for `foo' defined here; maybe ** should be added to the call?
(new)
test.rb:4: warning: The last argument is used as keyword parameters; maybe ** should be added to the call
test.rb:1: warning: The called method `foo' is defined here
For BasicObject, bind the Kernel respond_to? instance method to the
object and call it instead of calling the method directly.
Also, use bind_call(recv, ...) for better performance.
Fixes [Bug #16127]
This approach uses a flag bit on the final hash object in the regular splat,
as opposed to a previous approach that used a VM frame flag. The hash flag
approach is less invasive, and handles some cases that the VM frame flag
approach does not, such as saving the argument splat array and splatting it
later:
ruby2_keywords def foo(*args)
@args = args
bar
end
def bar
baz(*@args)
end
def baz(*args, **kw)
[args, kw]
end
foo(a:1) #=> [[], {a: 1}]
foo({a: 1}, **{}) #=> [[{a: 1}], {}]
foo({a: 1}) #=> 2.7: [[], {a: 1}] # and warning
foo({a: 1}) #=> 3.0: [[{a: 1}], {}]
It doesn't handle some cases that the VM frame flag handles, such as when
the final hash object is replaced using Hash#merge, but those cases are
probably less common and are unlikely to properly support keyword
argument separation.
Use ruby2_keywords to handle argument delegation in the delegate library.
Public instance methods added to a delegated class after the
creation of the delegate class were not returned by the
public_instance_methods class method of the delegate class.
Protected instance methods in the delegated class when the
delegate class is created were returned by the public_methods
instance method of the delegate class.
Patch mostly from Kenichi Kamiya <kachick1@gmail.com> in
GitHub pull request 926. Minor changes to get it to apply,
and to fix tests after applying by me.
Fixes [Bug #11512]
Methods that return classes often module_eval the given block
(e.g. Class.new and Struct.new). This allows DelegateClass to
work similarly. This makes it easier to use DelegateClass
directly without subclassing, so as not to create an unnecessary
subclass.
Implements [Feature #15842]
Instead, look for instance methods of Kernel.
Otherwise, instance methods of Module (which are methods of Kernel
itself) are mistakenly believed to exist, and it fails when calling
Kernel.instance_method().
Closes: https://github.com/ruby/ruby/pull/1422
FrozenError will be used instead of RuntimeError for exceptions
raised when there is an attempt to modify a frozen object. The
reason for this change is to differentiate exceptions related
to frozen objects from generic exceptions such as those generated
by Kernel#raise without an exception class.
