This revises the new P2P `Transport` interface and does some preliminary code cleanups and simplifications. The major change here is to add `Connection.Handshake()` for performing node handshakes (once the stream transport API is implemented, this can be done entirely independent of the transport). This moves most of the handshaking logic into the `Router`, such as prevention of head-of-line blocking, validation of peer's `NodeInfo`, controlling timeouts, and so on. This significantly simplifies transports, completely removes the need for internal goroutines, and shares common logic across all transports. This also allows varying the handshake `NodeInfo` across peers, e.g. to vary `ListenAddr`. Similarly, connection filtering is also moved into the switch/router so that it can be shared between transports.
Tendermint Tests
The unit tests (ie. the go test s) can be run with make test.
The integration tests can be run with make test_integrations.
Running the integrations test will build a docker container with local version of tendermint and run the following tests in docker containers:
- go tests, with --race
- includes test coverage
- app tests
- kvstore app over socket
- counter app over socket
- counter app over grpc
- persistence tests
- crash tendermint at each of many predefined points, restart, and ensure it syncs properly with the app
