General:
- Message encapsulation is temporary until integration with whisper
Incoming message handling:
- Implements a dispatcher for registering handler functions to pss topics
- Handlers can be any sort of function, and can send/receive on p2p.MsgReadWriter
- Actual p2p.Protocol handling now as pluggable convenience function
Sending and routing:
- Added temporary cache solution based on message hash digest
- Send and forward split up as separate methods
- Send is now payload agnostic (p2p.Protocol replies massaged in p2p.MsgWriter)
Tests:
- TestPssRandom...
Sends PSS between randomly selected nodes in different population magnitudes
- TestPssFullLinearEcho
A->B->C->B->A ping/pong over pss, where A and C are running pss
- TestPssFullRandom50Pct
10 nodes where 5 are running pss, 5 sends to/from random nodes
(messages currently get stuck in kad. routing, discarded by cache block)
- Protocoltester tests status unknown
