Issue #11117 has been reported by Jakub Jirutka.
----------------------------------------
Bug #11117: When you refine String with to_regexp, then it breaks Regexp.try_convert even when the refinement is not used
https://bugs.ruby-lang.org/issues/11117
* Author: Jakub Jirutka
* Status: Open
* Priority: High
* Assignee:
* ruby -v: 2.2.2p95
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN, 2.2: UNKNOWN
----------------------------------------
I’ve run into a very strange bug with refinements. Let me show you:
~~~ruby
module Ref
refine String do
def to_regexp
end
end
end
Regexp.try_convert('foo')
# or Regexp.union('foo', 'bar')
~~~
~~~
bug.rb:8:in `try_convert': undefined method `to_regexp' for "foo":String (NoMethodError)
from test.rb:8:in `<main>'
~~~
Note that the refinement is not used (_using_), only declared, and yet it has affected behaviour of the refined class! This problem occurs only when the method is named `to_string`. It seems that there’s some serious scoping issue with refinements.
I’ve reproduced this issue on MRI 2.2.2p95, 2.1.5p273, and 2.0.0p598.
