Module: Datadog::Profiling::Ext::Forking::ProcessDaemonPatch

Defined in:
lib/datadog/profiling/ext/forking.rb

Overview

A call to Process.daemon ( rubyapi.org/3.1/o/process#method-c-daemon ) forks the current process and keeps executing code in the child process, killing off the parent, thus effectively replacing it.

This monkey patch makes the ‘Kernel#at_fork` mechanism defined above also work in this situation.
