From ef0eb3b01b66fbbc97908667a3dd1e02d710cbb7 Mon Sep 17 00:00:00 2001 From: Tao Bao Date: Mon, 14 Nov 2016 21:29:52 -0800 Subject: updater: Fix the wrong return value for package_extract_file(). 'bool success = ExtractEntryToFile()' gives opposite result. Fix the issue and add testcases. Change the one-argument version of package_extract_file() to explicitly abort for non-existent zip entry. Note that this is NOT changing the behavior. Prior to this CL, it aborts from Evaluate() function, by giving a general cause code. Now it returns kPackageExtractFileFailure. BUg: 32903624 Test: recovery_component_test works.
