- split PubKeyMsg into PubKeyRequest / PubKeyResponse like other msgs
- NewRemoteSignerClient sends a pubkey request (once), return this err
OnStart()
- NewRemoteSignerClient returns an error if retrieving the pubkey fails
- remove GetAddress from PrivValidator interface
- GetPublicKey doesn't err but returns memoized public key from init
- fix tests
Ref: #2563
I added IPC as an unencrypted alternative to SocketPV.
Besides I fixed the following aspects of SocketPV:
Added locking since we are operating on a single socket
The connection deadline is extended every time a successful packet exchange happens; otherwise the connection would always die permanently x seconds after the connection was established.
Added a ping/heartbeat mechanism to keep the connection alive; native TCP keepalives do not work in this use-case
* Extend the SecureConn socket to extend its deadline
* Add locking & ping/heartbeat packets to SocketPV
* Implement IPC PV and abstract socket signing
* Refactored IPC and SocketPV
* Implement @melekes comments
* Fixes to rebase
