"""
|
|
Test that transaction announcements are only queued for peers that have
|
|
successfully completed the version handshake.
|
|
|
|
Topology:
|
|
|
|
tx_originator ----> node[0] <---- spy
|
|
|
|
We test that a transaction sent by tx_originator is only relayed to spy
|
|
if it was received after spy's version handshake completed.
|
|
|
|
1. Fully connect tx_originator
|
|
2. Connect spy (no version handshake)
|
|
3. tx_originator sends tx1
|
|
4. spy completes the version handshake
|
|
5. tx_originator sends tx2
|
|
6. We check that only tx2 is announced on the spy interface
