From c17bbb966a6e6891115f29f814d801e3ff4ee977 Mon Sep 17 00:00:00 2001 From: Fredy Wijaya Date: Wed, 4 Sep 2024 23:49:57 -0500 Subject: [PATCH] mobile: Stop the DNS cache when the network is unavailable (#35922) This PR fixes an issue on Android when the network was unavailable, Envoy Mobile would always refresh the DNS cache causing spurious DNS errors. This PR fixes the issue by cancelling the pending DNS queries and stopping the DNS refresh and timeout timers when the network is unavailable. As a result, this requires adding a new `DnsCache::stop` function. The `InternalEngine` API has also been updated by introducing `onDefaultNetworkAvailable`, `onDefaultNetworkChanged` and `onDefaultNetworkUnavailable` callbacks instead of using `setPreferredNetwork`, a method that has been incorrectly used for on network changed callback. By having these new callbacks, we now have a fine-grained control to refresh and stop the DNS caches. The `AndroidNetworkMonitor` has been reimplemented to use [ConnectivityManager.Network](https://developer.android.com/reference/android/net/ConnectivityManager.NetworkCallback) instead of the deprecated API and more tests has also been added.
