From 1efe0ebc5973ec8a06b881c087dae2183898504b Mon Sep 17 00:00:00 2001 From: Dean Deng Date: Wed, 13 Jan 2021 15:10:03 -0800 Subject: Switch uses of os.Getenv that check for empty string to os.LookupEnv. Whether the variable was found is already returned by syscall.Getenv. os.Getenv drops this value while os.Lookupenv passes it along.
