From 98f875eee713096b03728c5d7424be503d4dc4c1 Mon Sep 17 00:00:00 2001 From: Tao Bao Date: Mon, 7 May 2018 15:03:30 -0700 Subject: [PATCH] updater: Fix an issue when resuming an update. We cannot skip "new" commands while resuming an update with last_command_file, because they read in the data sequentially from the package. Bug: 69858743 Test: Interrupt an update that has new commands. Check the update log.
