Ruby 3.1.0 with Psych 4 forces YAML.safe_load and throws Psych::DisallowedClass #247

Closed doits closed 2 years ago

doits commented 2 years ago

Describe the bug

Just a heads up for Ruby 3.1: It ships with Psych 4 by default and uses YAML.safe_load even with YAML.load, see https://bugs.ruby-lang.org/issues/17866 and https://github.com/ruby/psych/blob/75ab76e7888df143012afb1cb6b89ccca28a4451/lib/psych.rb#L369-L377.

You get this error for example:

/lib/ruby/3.1.0/psych/class_loader.rb:99:in `find': Tried to load unspecified class: Range (Psych::DisallowedClass)

To Reproduce Steps to reproduce the behavior:

Install ruby 3.1.0 with Psych 4
['ALB'].localize('en').sort

Environment Ruby 3.1.0 with Psych 4.0.3

Possible solutions

Refactor all YAML data to be simpler and not to use special classes?
Use YAML.safe_load and manually allow whatever classes are needed (so it works on new and old rubies)
Force the use of Psych 3 while working to support 4, maybe it can be added as an explicit dependency of the gem?

Hey there @doits, thanks for letting me know about this. I've worked up a fix and released it as v6.11.0 😄
