Description Keith Rollin 2020-05-05 22:17:31 PDT 
In Bug 205295, NetworkResourceLoader logging was improved, with one of the changes being that the PID of parent process that invoked the Network process was logged at the start of NetworkResourceLoader::start(). However, there was an execution path that skipped calling start() (NetworkConnectionToWebProcess::scheduleResourceLoad -> NetworkResourceLoader ::startWithServiceWorker -> serviceWorkerDidNotHandle -> restartNetworkLoad -> startNetworkLoad), and so the the logging would not show the parent PID. This logging is needed for diagnostic purposes, so tweak the logging a little bit more in order to ensure we emit it. In this change, logging is added to various loading-related NetworkConnectionToWebProcess entry points (not just scheduleResourceLoad) in order to (a) ensure we emit the logging we want and (b) to give a clearer picture of what operations are being invoked in the Network process.
