Accessing ENV from Ractor raises IsolationError
ruby 3.0.0p0 (2020-12-25 revision 95aff21468) [x86_64-linux]
Accessing ENV variables from a Ractor will raise Ractor::IsolationError, as the Hash is non-shareable.
How to reproduce¶
ractor = Ractor.new do ENV['PATH'] end ractor.take
Expectation and result¶
Ractor raises Ractor::IsolationError for ENV
Expect to be able to access ENV variables from Ractors without raising an error.
`block in <main>': can not access non-shareable objects in constant Object::ENV by non-main Ractor. (Ractor::IsolationError)
Attempting to create a shareable copy of ENV currently fails:
Ractor.make_shareable(ENV, copy: true) # TypeError: cannot freeze ENV # from <internal:ractor>:812:in `freeze'
- If ENV is a mutable hash, make a Ractor-compatible copy of ENV isolated to that Ractor.

ENV should be shareable.
It is in my task list, but not high priority.
