TracePoint.allow_reentry

# File tmp/rubies/ruby-3.1.3/trace_point.rb, line 150
def self.allow_reentry
  Primitive.tracepoint_allow_reentry
end

In general, while a TracePoint callback is running, other registered callbacks are not called to avoid confusion by reentrance. This method allows the reentrance in a given block. This method should be used carefully, otherwise the callback can be easily called infinitely.

If this method is called when the reentrance is already allowed, it raises a RuntimeError.

Ruby version changes

3.1
- TracePoint.allow_reentry is added to allow reenter while TracePoint callback. [Feature #15912]
