2020-07-30Extract version number from the sourceNobuyoshi Nakada
"requiring version.rb" strategy has some issues. - cannot work when cross-compiling - often introduces wrong namespace - must know the superclasses - costs at each runtime than at build-time etc. Notes: Merged: https://github.com/ruby/ruby/pull/3375
2020-07-09Add instance_methods to class generated by DelegateClassMasataka Pocke Kuwabara
Also, make DelegateClass.instance_method fallback to superclass. Fixes [Bug #16982] Notes: Merged: https://github.com/ruby/ruby/pull/3221 Merged-By: jeremyevans <code@jeremyevans.net>
2020-06-25Add require to Delegator examplesRichard Schneeman
In Ruby 2.7.1 SimpeDelegator cannot be used without requiring `delegate` this PR adds the require to the first example for each class so that devs don't have to hunt for what require to use. Notes: Merged: https://github.com/ruby/ruby/pull/3254
2020-03-22Support obj.clone(freeze: true) for freezing cloneJeremy Evans
This freezes the clone even if the receiver is not frozen. It is only for consistency with freeze: false not freezing the clone even if the receiver is frozen. Because Object#clone is now partially implemented in Ruby and not fully implemented in C, freeze: nil must be supported to provide the default behavior of only freezing the clone if the receiver is frozen. This requires modifying delegate and set, to set freeze: nil instead of freeze: true as the keyword parameter for initialize_clone. Those are the two libraries in stdlib that override initialize_clone. Implements [Feature #16175] Notes: Merged: https://github.com/ruby/ruby/pull/2969
2020-02-03Fix SimpleDelegator respond_to? regressionJean Boussier
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?`. Notes: Merged: https://github.com/ruby/ruby/pull/2875
2020-01-30delegate.rb: fixed keyword arguments in DelegateClassNobuyoshi Nakada
`Delegator.delegating_block` should delegate keyword arguments separately. [ruby-core:96949] Notes: Merged: https://github.com/ruby/ruby/pull/2852
2020-01-03Call initialize_clone with freeze: false if clone called with freeze: falseJeremy Evans
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] Notes: Merged: https://github.com/ruby/ruby/pull/2816
2019-11-18Deprecate taint/trust and related methods, and make the methods no-opsJeremy Evans
This removes the related tests, and puts the related specs behind version guards. This affects all code in lib, including some libraries that may want to support older versions of Ruby. Notes: Merged: https://github.com/ruby/ruby/pull/2476
2019-10-10Support delegates for BasicObjectJeremy Evans
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] Notes: Merged: https://github.com/ruby/ruby/pull/2546
2019-09-25Add Module#ruby2_keywords for passing keywords through regular argument splatsJeremy Evans
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. Notes: Merged: https://github.com/ruby/ruby/pull/2477
2019-06-02delegate.rb: markup method namesNobuyoshi Nakada
2019-05-30Fix visibility of some methods when using DelegateClassJeremy Evans
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]
2019-05-30Allow DelegateClass() to module_eval given blockJeremy Evans
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]
2019-05-13delegate.rb: don't look for methods on KernelÉtienne Barrié
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
2019-05-10Fix missing `\A`Kazuhiro NISHIYAMA
2017-12-12Add uplevel keyword to Kernel#warn and use itshyouhei
If uplevel keyword is given, the warning message is prepended with caller file and line information and the string "warning: ". The use of the uplevel keyword makes Kernel#warn format output similar to how rb_warn formats output. This patch modifies net/ftp and net/imap to use Kernel#warn instead of $stderr.puts or $stderr.printf, since they are used for printing warnings. This makes lib/cgi/core and tempfile use $stderr.puts instead of warn for debug logging, since they are used for debug printing and not for warning. This does not modify bundler, rubygems, or rdoc, as those are maintained outside of ruby and probably wish to remain backwards compatible with older ruby versions. rb_warn_m code is originally from nobu, but I've changed it so that it only includes the path and lineno from uplevel (not the method), and also prepends the string "warning: ", to make it more similar to rb_warn.
