From 1fc9cc0d0e1dfafb8d29dba8d01f09587d870026 Mon Sep 17 00:00:00 2001 From: Olivier Robin Date: Thu, 18 Apr 2019 18:06:31 +0200 Subject: [Breakpad iOS] Add a callback on report upload completion. This CL adds a result callback on report upload completion. On failure, Breakpad deletes the configuration file and does retry to upload a report. Using this callback, the client will be able to log some metrics and to act on upload failure.
