From a typical tinderbox log: 19:08:26 INFO - [Parent 3208] WARNING: NS_ENSURE_SUCCESS(rv, false) failed with result 0x80004005: file /builds/slave/try-lx-d-000000000000000000000/build/src/netwerk/protocol/http/HttpBaseChannel.cpp, line 1952 19:08:26 INFO - [Parent 3208] WARNING: NS_ENSURE_SUCCESS(rv, rv) failed with result 0x80004005: file /builds/slave/try-lx-d-000000000000000000000/build/src/dom/workers/ServiceWorkerManager.cpp, line 2370 repeated a bajillion times. The problem is that ServiceWorkerManager::GetDocumentRegistration will return NS_ERROR_FAILURE if the hashtable lookup returns "no entry". This (common case!) situation will lead to an immediate warning in ServiceWorkerManager::IsControlled (the second warning above) and then propagate up the tree to other consumers, leading to more warnings.
I agree, but I'm not that familiar with SWM. Nikhil, can you look at silencing these?
