From 006e78cecbdd70f40a14a1485cd6a24b6fab2ee1 Mon Sep 17 00:00:00 2001 From: Joyee Cheung Date: Sun, 10 Feb 2019 17:58:41 +0800 Subject: [PATCH] process: refactor lib/internal/bootstrap/node.js - Use `deprecate` from `internal/util` instead of from `util` - Split `setupGlobalVariables()` into `setupGlobalProxy()` and `setupBuffer()`, and move out manipulation of the process object.
