2021-12-02Lazily create singletons on instance_{exec,eval} (#5146)John Hawthorn
* Lazily create singletons on instance_{exec,eval} Previously when instance_exec or instance_eval was called on an object, that object would be given a singleton class so that method definitions inside the block would be added to the object rather than its class. This commit aims to improve performance by delaying the creation of the singleton class unless/until one is needed for method definition. Most of the time instance_eval is used without any method definition. This was implemented by adding a flag to the cref indicating that it represents a singleton of the object rather than a class itself. In this case CREF_CLASS returns the object's existing class, but in cases that we are defining a method (either via definemethod or VM_SPECIAL_OBJECT_CBASE which is used for undef and alias). This also happens to fix what I believe is a bug. Previously instance_eval behaved differently with regards to constant access for true/false/nil than for all other objects. I don't think this was intentional. String::Foo = "foo" "".instance_eval("Foo") # => "foo" Integer::Foo = "foo" 123.instance_eval("Foo") # => "foo" TrueClass::Foo = "foo" true.instance_eval("Foo") # NameError: uninitialized constant Foo This also slightly changes the error message when trying to define a method through instance_eval on an object which can't have a singleton class. Before: $ ruby -e '123.instance_eval { def foo; end }' -e:1:in `block in <main>': no class/module to add method (TypeError) After: $ ./ruby -e '123.instance_eval { def foo; end }' -e:1:in `block in <main>': can't define singleton (TypeError) IMO this error is a small improvement on the original and better matches the (both old and new) message when definging a method using `def self.` $ ruby -e '123.instance_eval{ def self.foo; end }' -e:1:in `block in <main>': can't define singleton (TypeError) Co-authored-by: Matthew Draper <matthew@trebex.net> * Remove "under" argument from yield_under * Move CREF_SINGLETON_SET into vm_cref_new * Simplify vm_get_const_base * Fix leaf VM_SPECIAL_OBJECT_CONST_BASE Co-authored-by: Matthew Draper <matthew@trebex.net> Notes: Merged-By: jhawthorn <john@hawthorn.email>

2020-01-03Make eval(code, binding) use (eval) as __FILE__ and 1 as __LINE__Jeremy Evans
This removes the warning that was added in 3802fb92ff8c83eed3e867db20f72c53932f542d, and switches the behavior so that the eval does not use the binding's __FILE__ and __LINE__ implicitly. Fixes [Bug #4352] Notes: Merged: https://github.com/ruby/ruby/pull/2816

2017-12-12Add FrozenError as a subclass of RuntimeErrorshyouhei
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.
