From a2ca1d53300b980c586b466e56a9c92619dae14a Mon Sep 17 00:00:00 2001 From: Russ Cox Date: Thu, 29 Oct 2020 14:17:47 -0400 Subject: [PATCH] all: update to use os.ReadFile, os.WriteFile, os.CreateTemp, os.MkdirTemp As part of #42026, these helpers from io/ioutil were moved to os. (ioutil.TempFile and TempDir became os.CreateTemp and MkdirTemp.) Update the Go tree to use the preferred names. As usual, code compiled with the Go 1.4 bootstrap toolchain and code vendored from other sources is excluded. ReadDir changes are in a separate CL, because they are not a simple search and replace. For #42026.
