"""Test bitcoind with different proxy configuration.
|
||
|
|
|
||
|
|
Test plan:
|
||
|
|
- Start bitcoind's with different proxy configurations
|
||
|
|
- Use addnode to initiate connections
|
||
|
|
- Verify that proxies are connected to, and the right connection command is given
|
||
|
|
- Proxy configurations to test on bitcoind side:
|
||
|
|
- `-proxy` (proxy everything)
|
||
|
|
- `-onion` (proxy just onions)
|
||
|
|
- `-proxyrandomize` Circuit randomization
|
||
|
|
- Proxy configurations to test on proxy side,
|
||
|
|
- support no authentication (other proxy)
|
||
|
|
- support no authentication + user/pass authentication (Tor)
|
||
|
|
- proxy on IPv6
|
||
|
|
|
||
|
|
- Create various proxies (as threads)
|
||
|
|
- Create nodes that connect to them
|
||
|
|
- Manipulate the peer connections using addnode (onetry) and observe effects
|
||
|
|
- Test the getpeerinfo `network` field for the peer
|
||
|
|
|
||
|
|
addnode connect to IPv4
|
||
|
|
addnode connect to IPv6
|
||
|
|
addnode connect to onion
|
||
|
|
addnode connect to generic DNS name
|
||
|
|
|
||
|
|
- Test getnetworkinfo for each node
