"""Test various net timeouts.
|
|
|
|
- Create three bitcoind nodes:
|
|
|
|
no_verack_node - we never send a verack in response to their version
|
|
no_version_node - we never send a version (only a ping)
|
|
no_send_node - we never send any P2P message.
|
|
|
|
- Start all three nodes
|
|
- Wait 1 second
|
|
- Assert that we're connected
|
|
- Send a ping to no_verack_node and no_version_node
|
|
- Wait 1 second
|
|
- Assert that we're still connected
|
|
- Send a ping to no_verack_node and no_version_node
|
|
- Wait 2 seconds
|
|
- Assert that we're no longer connected (timeout to receive version/verack is 3 seconds)
