From a2679f55b5b14092db88fab3799f06e6b68e439e Mon Sep 17 00:00:00 2001 From: David Kalnischkies Date: Tue, 7 Apr 2015 14:34:04 +0200 Subject: properly handle expected filesize in https The worker expects that the methods tell him when they start or finish downloading a file. Various information pieces are passed along in this report including the (expected) filesize. https is using a "global" struct for reporting which made it 'reuse' incorrect values in some cases like a non-existent InRelease fallbacking to Release{,.gpg} resulting in an incorrect size-mismatch warning scaring and desensitizing users as well as being subject to a race between the write_data and progress callbacks generating incorrect progress reporting and potentially the same error message. Other branches as well as the bugreports contain 'better' fixes making the struct local and other sensible changes, but are larger as a result, so in this version we opted for short diff with minimal effect above else instead.
