* lite2: add Start method There are few reasons to do that: 1) separation of state and dynamics (some users will want to delay starting the light client; does not matter we should not allow them to create a light client object) 2) less important, but some users might not need autoUpdateRoutine and removeNoLongerTrustedHeadersRoutine routines * lite2: wait till routines are finished in Stop because they are started in Start, it feels more natural to wait for them to finish in Stop. * lite2: add TrustedValidatorSet func * refactor cleanup code * changed restore header and val function to handle negative height * reverted restoreTrustedHeaderAndNextVals() functionality Co-authored-by: Anton Kaliaev <anton.kalyaev@gmail.com>

# Tendermint P2P Tests
These scripts facilitate setting up and testing a local testnet using docker containers.
Setup your own local testnet as follows.
For consistency, we assume all commands are run from the Tendermint repository root.
First, build the docker image:
```
docker build -t tendermint_tester -f ./test/docker/Dockerfile .
```
Now create the docker network:
```
docker network create --driver bridge --subnet 172.57.0.0/16 my_testnet
```
This gives us a new network with IP addresses in the rage `172.57.0.0 - 172.57.255.255`.
Peers on the network can have any IP address in this range.
For our four node network, let's pick `172.57.0.101 - 172.57.0.104`.
Since we use Tendermint's default listening port of 26656, our list of seed nodes will look like:
```
172.57.0.101:26656,172.57.0.102:26656,172.57.0.103:26656,172.57.0.104:26656
```
Now we can start up the peers. We already have config files setup in `test/p2p/data/`.
Let's use a for-loop to start our peers:
```
for i in $(seq 1 4); do
docker run -d \
--net=my_testnet\
--ip="172.57.0.$((100 + $i))" \
--name local_testnet_$i \
--entrypoint tendermint \
-e TMHOME=/go/src/github.com/tendermint/tendermint/test/p2p/data/mach$((i-1)) \
tendermint_tester node --p2p.persistent_peers 172.57.0.101:26656,172.57.0.102:26656,172.57.0.103:26656,172.57.0.104:26656 --proxy_app=kvstore
done
```
If you now run `docker ps`, you'll see your containers!
We can confirm they are making blocks by checking the `/status` message using `curl` and `jq` to pretty print the output json:
```
curl 172.57.0.101:26657/status | jq .
```
## IPv6 tests
IPv6 tests require a Docker daemon with IPv6 enabled, by setting the following in `daemon.json`:
```json
{
"ipv6": true,
"fixed-cidr-v6": "2001:db8:1::/64"
}
```
In Docker for Mac, this is done via Preferences → Docker Engine.
Once set, run IPv6 tests via `make test_p2p_ipv6`.
