Overview

require inside a non-main Ractor works on Ruby 4.0 by proxying the call to the main Ractor; but that serializes every Ractor through a single lock, and it means load-time side effects run mid-request. autoload is the same hazard in disguise: the require fires whenever the constant happens to be resolved first, possibly inside a Ractor.

Instance Method Details

#visit_begin_node(node) ⇒ Object

A require under a rescue is conditional by construction (optional dependencies, tzinfo's tzinfo-data); hoisting it to an unguarded top-level require breaks every installation without the feature.
