I was investigating issues I am having with Whisper support. I've enabled Whisper on a custom test network and inserted traces into Whisper handler implementation (Network<T> and NetworkProtocolHandler for Network<T>) and I noticed that the handler was never invoked. After further research on this matter, I found out that AttachedProtocol's register function does nothing: https://github.com/paritytech/parity/blob/master/sync/src/api.rs#L172 but there was an implementation originally: 99075ad#diff-5212acb6bcea60e9804ba7b50f6fe6ec and it did the actual expected logic of registering the protocol in the NetworkService. However, as of 16d84f8#diff-5212acb6bcea60e9804ba7b50f6fe6ec ("finished removing ipc") this implementation is gone and only the no-op function is left. Which leads me to a conclusion that in fact Whisper's handler never gets registered in the service and therefore two nodes won't communicate using it. Solution: Resurrect original non-empty `AttachedProtocols.register` implementation Resolves openethereum#7566

I was investigating issues I am having with Whisper support. I've enabled Whisper on a custom test network and inserted traces into Whisper handler implementation (
Network<T>andNetworkProtocolHandler for Network<T>) and I noticed that the handler was never invoked.After further research on this matter, I found out that

Is there something I am missing and this is how it is supposed to be or was that implementation of
AttachedProtocol.registerremoved in error? Is there something else I should look at to have a complete picture?The text was updated successfully, but these errors were encountered:
