Geth js commands coming through jail with a callback will now be executed truly asynchronously blocking jail only when an actual interaction with VM is performed.
Technically, it registers a new handler jeth.sendAsync which executes functions with callbacks asynchronously.
Changes include:
1. Send and SendAsync now use cell.VM instead of otto.Otto providing proper locking.
2. Unmarshalling in ExecuionPolicy.ExecuteWithClient is now done into var result interface{} instead of var result json.RawMessage because test case 0 of TestJailWhisper failed providing byte codes instead of 5.0.
3. Due to the asynchronous nature of web3 calls new weird timeouts in tests have been introduced. They may fail sometimes but I gave up trying to implement a more reliable and readable solution.
The goal of this PR is to make geth/api tests to finally pass from the beginning to the end. I tried to achieve it here by:
Removing calls to common.PanicAfter so that we know which tests fail the most,
Better sync of some tests using channels,
Small test improvements.
This PR refactors RPC subsystem for status-go:
cleans up two different RPC client implementations (RPCManager and rpc.Client)
creates new package under geth/rpc
moves routing logic into this package (rpc.(*router))
add tests for routing
cleans up NodeManager
Geth requests have been revised and if the upstream is enabled, only queries regarding working Ethereum protocol are routed to upstream.
Whisper, most web3 requests and various utility methods are still routed to the local node as well as requests for accounts.
Now all transactions in both cases are waiting for CompleteTransaction or DiscardTransaction to proceed independently from their destination: upstream of local
IMPORTANT: The known issue is that in case of configured UpstreamRPCServer transactions are sent immediately not waiting for CompleteTransaction or DiscardTransaction which brings inconsistency in behaviour and acts as a security breach.
* new UpstreamRPConfig in geth/params to provide upstream configuration
* conditional start of ethereum blockchain sequence based on NodeConfig.UpstreamConfig.Enabled flag state
