From 5e535014dd7961fbf812abeaa27f3339775031f1 Mon Sep 17 00:00:00 2001 From: Tao Bao Date: Thu, 16 Mar 2017 17:37:38 -0700 Subject: Drop the dependency on 'ui' in verify_file(). verify_file() has a dependency on the global variable of 'ui' for posting the verification progress, which requires the users of libverifier to provide a UI instance. This CL adds an optional argument to verify_file() so that it can post the progress through the provided callback function. As a result, we can drop the MockUI class in verifier_test.cpp. Test: recovery_component_test passes. Test: verify_file() posts progress update when installing an OTA.
