* Add instance_methods to class generated by DelegateClassMasataka Pocke Kuwabara2020-07-091-0/+34
| | | | | Also, make DelegateClass.instance_method fallback to superclass. Fixes [Bug #16982]
* Fix SimpleDelegator respond_to? regressionJean Boussier2020-02-031-0/+14
| | | | | | | | | 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?`.
* delegate.rb: fixed keyword arguments in DelegateClassNobuyoshi Nakada2020-01-301-0/+8
| | | | | `Delegator.delegating_block` should delegate keyword arguments separately. [ruby-core:96949]
* Call initialize_clone with freeze: false if clone called with freeze: falseJeremy Evans2020-01-031-0/+15
| | | | | | | | | | | | | | | | | | | 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]

(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
* Support delegates for BasicObjectJeremy Evans2019-10-101-0/+8
| | | | | | | | | 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]
* Add Module#ruby2_keywords for passing keywords through regular argument splatsJeremy Evans2019-09-251-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* Fix visibility of some methods when using DelegateClassJeremy Evans2019-05-301-0/+31
| | | | | | | | | | | | | | | | 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]
* Allow DelegateClass() to module_eval given blockJeremy Evans2019-05-301-0/+7
| | | | | | | | | | 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]
* delegate.rb: don't look for methods on KernelÉtienne Barrié2019-05-131-0/+7
| | | | | | | | | 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
* Add FrozenError as a subclass of RuntimeErrorshyouhei2017-12-121-2/+2
| | | | | | | | | | | | | | 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.
